Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - -[This is the first released version of the Lesser GPL. It also counts - as the successor of the GNU Library Public License, version 2, hence - the version number 2.1.] - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -Licenses are intended to guarantee your freedom to share and change -free software--to make sure the software is free for all its users. - - This license, the Lesser General Public License, applies to some -specially designated software packages--typically libraries--of the -Free Software Foundation and other authors who decide to use it. You -can use it too, but we suggest you first think carefully about whether -this license or the ordinary General Public License is the better -strategy to use in any particular case, based on the explanations below. - - When we speak of free software, we are referring to freedom of use, -not price. Our General Public Licenses are designed to make sure that -you have the freedom to distribute copies of free software (and charge -for this service if you wish); that you receive source code or can get -it if you want it; that you can change the software and use pieces of -it in new free programs; and that you are informed that you can do -these things. - - To protect your rights, we need to make restrictions that forbid -distributors to deny you these rights or to ask you to surrender these -rights. These restrictions translate to certain responsibilities for -you if you distribute copies of the library or if you modify it. - - For example, if you distribute copies of the library, whether gratis -or for a fee, you must give the recipients all the rights that we gave -you. You must make sure that they, too, receive or can get the source -code. If you link other code with the library, you must provide -complete object files to the recipients, so that they can relink them -with the library after making changes to the library and recompiling -it. And you must show them these terms so they know their rights. - - We protect your rights with a two-step method: (1) we copyright the -library, and (2) we offer you this license, which gives you legal -permission to copy, distribute and/or modify the library. - - To protect each distributor, we want to make it very clear that -there is no warranty for the free library. Also, if the library is -modified by someone else and passed on, the recipients should know -that what they have is not the original version, so that the original -author's reputation will not be affected by problems that might be -introduced by others. - - Finally, software patents pose a constant threat to the existence of -any free program. We wish to make sure that a company cannot -effectively restrict the users of a free program by obtaining a -restrictive license from a patent holder. Therefore, we insist that -any patent license obtained for a version of the library must be -consistent with the full freedom of use specified in this license. - - Most GNU software, including some libraries, is covered by the -ordinary GNU General Public License. This license, the GNU Lesser -General Public License, applies to certain designated libraries, and -is quite different from the ordinary General Public License. We use -this license for certain libraries in order to permit linking those -libraries into non-free programs. - - When a program is linked with a library, whether statically or using -a shared library, the combination of the two is legally speaking a -combined work, a derivative of the original library. The ordinary -General Public License therefore permits such linking only if the -entire combination fits its criteria of freedom. The Lesser General -Public License permits more lax criteria for linking other code with -the library. - - We call this license the "Lesser" General Public License because it -does Less to protect the user's freedom than the ordinary General -Public License. It also provides other free software developers Less -of an advantage over competing non-free programs. These disadvantages -are the reason we use the ordinary General Public License for many -libraries. However, the Lesser license provides advantages in certain -special circumstances. - - For example, on rare occasions, there may be a special need to -encourage the widest possible use of a certain library, so that it becomes -a de-facto standard. To achieve this, non-free programs must be -allowed to use the library. A more frequent case is that a free -library does the same job as widely used non-free libraries. In this -case, there is little to gain by limiting the free library to free -software only, so we use the Lesser General Public License. - - In other cases, permission to use a particular library in non-free -programs enables a greater number of people to use a large body of -free software. For example, permission to use the GNU C Library in -non-free programs enables many more people to use the whole GNU -operating system, as well as its variant, the GNU/Linux operating -system. - - Although the Lesser General Public License is Less protective of the -users' freedom, it does ensure that the user of a program that is -linked with the Library has the freedom and the wherewithal to run -that program using a modified version of the Library. - - The precise terms and conditions for copying, distribution and -modification follow. Pay close attention to the difference between a -"work based on the library" and a "work that uses the library". The -former contains code derived from the library, whereas the latter must -be combined with the library in order to run. - - GNU LESSER GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License Agreement applies to any software library or other -program which contains a notice placed by the copyright holder or -other authorized party saying it may be distributed under the terms of -this Lesser General Public License (also called "this License"). -Each licensee is addressed as "you". - - A "library" means a collection of software functions and/or data -prepared so as to be conveniently linked with application programs -(which use some of those functions and data) to form executables. - - The "Library", below, refers to any such software library or work -which has been distributed under these terms. A "work based on the -Library" means either the Library or any derivative work under -copyright law: that is to say, a work containing the Library or a -portion of it, either verbatim or with modifications and/or translated -straightforwardly into another language. (Hereinafter, translation is -included without limitation in the term "modification".) - - "Source code" for a work means the preferred form of the work for -making modifications to it. For a library, complete source code means -all the source code for all modules it contains, plus any associated -interface definition files, plus the scripts used to control compilation -and installation of the library. - - Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running a program using the Library is not restricted, and output from -such a program is covered only if its contents constitute a work based -on the Library (independent of the use of the Library in a tool for -writing it). Whether that is true depends on what the Library does -and what the program that uses the Library does. - - 1. You may copy and distribute verbatim copies of the Library's -complete source code as you receive it, in any medium, provided that -you conspicuously and appropriately publish on each copy an -appropriate copyright notice and disclaimer of warranty; keep intact -all the notices that refer to this License and to the absence of any -warranty; and distribute a copy of this License along with the -Library. - - You may charge a fee for the physical act of transferring a copy, -and you may at your option offer warranty protection in exchange for a -fee. - - 2. You may modify your copy or copies of the Library or any portion -of it, thus forming a work based on the Library, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) The modified work must itself be a software library. - - b) You must cause the files modified to carry prominent notices - stating that you changed the files and the date of any change. - - c) You must cause the whole of the work to be licensed at no - charge to all third parties under the terms of this License. - - d) If a facility in the modified Library refers to a function or a - table of data to be supplied by an application program that uses - the facility, other than as an argument passed when the facility - is invoked, then you must make a good faith effort to ensure that, - in the event an application does not supply such function or - table, the facility still operates, and performs whatever part of - its purpose remains meaningful. - - (For example, a function in a library to compute square roots has - a purpose that is entirely well-defined independent of the - application. Therefore, Subsection 2d requires that any - application-supplied function or table used by this function must - be optional: if the application does not supply it, the square - root function must still compute square roots.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Library, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Library, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote -it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Library. - -In addition, mere aggregation of another work not based on the Library -with the Library (or with a work based on the Library) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may opt to apply the terms of the ordinary GNU General Public -License instead of this License to a given copy of the Library. To do -this, you must alter all the notices that refer to this License, so -that they refer to the ordinary GNU General Public License, version 2, -instead of to this License. (If a newer version than version 2 of the -ordinary GNU General Public License has appeared, then you can specify -that version instead if you wish.) Do not make any other change in -these notices. - - Once this change is made in a given copy, it is irreversible for -that copy, so the ordinary GNU General Public License applies to all -subsequent copies and derivative works made from that copy. - - This option is useful when you wish to copy part of the code of -the Library into a program that is not a library. - - 4. You may copy and distribute the Library (or a portion or -derivative of it, under Section 2) in object code or executable form -under the terms of Sections 1 and 2 above provided that you accompany -it with the complete corresponding machine-readable source code, which -must be distributed under the terms of Sections 1 and 2 above on a -medium customarily used for software interchange. - - If distribution of object code is made by offering access to copy -from a designated place, then offering equivalent access to copy the -source code from the same place satisfies the requirement to -distribute the source code, even though third parties are not -compelled to copy the source along with the object code. - - 5. A program that contains no derivative of any portion of the -Library, but is designed to work with the Library by being compiled or -linked with it, is called a "work that uses the Library". Such a -work, in isolation, is not a derivative work of the Library, and -therefore falls outside the scope of this License. - - However, linking a "work that uses the Library" with the Library -creates an executable that is a derivative of the Library (because it -contains portions of the Library), rather than a "work that uses the -library". The executable is therefore covered by this License. -Section 6 states terms for distribution of such executables. - - When a "work that uses the Library" uses material from a header file -that is part of the Library, the object code for the work may be a -derivative work of the Library even though the source code is not. -Whether this is true is especially significant if the work can be -linked without the Library, or if the work is itself a library. The -threshold for this to be true is not precisely defined by law. - - If such an object file uses only numerical parameters, data -structure layouts and accessors, and small macros and small inline -functions (ten lines or less in length), then the use of the object -file is unrestricted, regardless of whether it is legally a derivative -work. (Executables containing this object code plus portions of the -Library will still fall under Section 6.) - - Otherwise, if the work is a derivative of the Library, you may -distribute the object code for the work under the terms of Section 6. -Any executables containing that work also fall under Section 6, -whether or not they are linked directly with the Library itself. - - 6. As an exception to the Sections above, you may also combine or -link a "work that uses the Library" with the Library to produce a -work containing portions of the Library, and distribute that work -under terms of your choice, provided that the terms permit -modification of the work for the customer's own use and reverse -engineering for debugging such modifications. - - You must give prominent notice with each copy of the work that the -Library is used in it and that the Library and its use are covered by -this License. You must supply a copy of this License. If the work -during execution displays copyright notices, you must include the -copyright notice for the Library among them, as well as a reference -directing the user to the copy of this License. Also, you must do one -of these things: - - a) Accompany the work with the complete corresponding - machine-readable source code for the Library including whatever - changes were used in the work (which must be distributed under - Sections 1 and 2 above); and, if the work is an executable linked - with the Library, with the complete machine-readable "work that - uses the Library", as object code and/or source code, so that the - user can modify the Library and then relink to produce a modified - executable containing the modified Library. (It is understood - that the user who changes the contents of definitions files in the - Library will not necessarily be able to recompile the application - to use the modified definitions.) - - b) Use a suitable shared library mechanism for linking with the - Library. A suitable mechanism is one that (1) uses at run time a - copy of the library already present on the user's computer system, - rather than copying library functions into the executable, and (2) - will operate properly with a modified version of the library, if - the user installs one, as long as the modified version is - interface-compatible with the version that the work was made with. - - c) Accompany the work with a written offer, valid for at - least three years, to give the same user the materials - specified in Subsection 6a, above, for a charge no more - than the cost of performing this distribution. - - d) If distribution of the work is made by offering access to copy - from a designated place, offer equivalent access to copy the above - specified materials from the same place. - - e) Verify that the user has already received a copy of these - materials or that you have already sent this user a copy. - - For an executable, the required form of the "work that uses the -Library" must include any data and utility programs needed for -reproducing the executable from it. However, as a special exception, -the materials to be distributed need not include anything that is -normally distributed (in either source or binary form) with the major -components (compiler, kernel, and so on) of the operating system on -which the executable runs, unless that component itself accompanies -the executable. - - It may happen that this requirement contradicts the license -restrictions of other proprietary libraries that do not normally -accompany the operating system. Such a contradiction means you cannot -use both them and the Library together in an executable that you -distribute. - - 7. You may place library facilities that are a work based on the -Library side-by-side in a single library together with other library -facilities not covered by this License, and distribute such a combined -library, provided that the separate distribution of the work based on -the Library and of the other library facilities is otherwise -permitted, and provided that you do these two things: - - a) Accompany the combined library with a copy of the same work - based on the Library, uncombined with any other library - facilities. This must be distributed under the terms of the - Sections above. - - b) Give prominent notice with the combined library of the fact - that part of it is a work based on the Library, and explaining - where to find the accompanying uncombined form of the same work. - - 8. You may not copy, modify, sublicense, link with, or distribute -the Library except as expressly provided under this License. Any -attempt otherwise to copy, modify, sublicense, link with, or -distribute the Library is void, and will automatically terminate your -rights under this License. However, parties who have received copies, -or rights, from you under this License will not have their licenses -terminated so long as such parties remain in full compliance. - - 9. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Library or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Library (or any work based on the -Library), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Library or works based on it. - - 10. Each time you redistribute the Library (or any work based on the -Library), the recipient automatically receives a license from the -original licensor to copy, distribute, link with or modify the Library -subject to these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties with -this License. - - 11. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Library at all. For example, if a patent -license would not permit royalty-free redistribution of the Library by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Library. - -If any portion of this section is held invalid or unenforceable under any -particular circumstance, the balance of the section is intended to apply, -and the section as a whole is intended to apply in other circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 12. If the distribution and/or use of the Library is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Library under this License may add -an explicit geographical distribution limitation excluding those countries, -so that distribution is permitted only in or among countries not thus -excluded. In such case, this License incorporates the limitation as if -written in the body of this License. - - 13. The Free Software Foundation may publish revised and/or new -versions of the Lesser General Public License from time to time. -Such new versions will be similar in spirit to the present version, -but may differ in detail to address new problems or concerns. - -Each version is given a distinguishing version number. If the Library -specifies a version number of this License which applies to it and -"any later version", you have the option of following the terms and -conditions either of that version or of any later version published by -the Free Software Foundation. If the Library does not specify a -license version number, you may choose any version ever published by -the Free Software Foundation. - - 14. If you wish to incorporate parts of the Library into other free -programs whose distribution conditions are incompatible with these, -write to the author to ask for permission. For software which is -copyrighted by the Free Software Foundation, write to the Free -Software Foundation; we sometimes make exceptions for this. Our -decision will be guided by the two goals of preserving the free status -of all derivatives of our free software and of promoting the sharing -and reuse of software generally. - - NO WARRANTY - - 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO -WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. -EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR -OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY -KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE -IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE -LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME -THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN -WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY -AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU -FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR -CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE -LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING -RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A -FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF -SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH -DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Libraries - - If you develop a new library, and you want it to be of the greatest -possible use to the public, we recommend making it free software that -everyone can redistribute and change. You can do so by permitting -redistribution under these terms (or, alternatively, under the terms of the -ordinary General Public License). - - To apply these terms, attach the following notices to the library. It is -safest to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least the -"copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This library is free software; you can redistribute it and/or - modify it under the terms of the GNU Lesser General Public - License as published by the Free Software Foundation; either - version 2.1 of the License, or (at your option) any later version. - - This library is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Optionally, type `make check' to run any self-tests that come with - the package. - - 4. Type `make install' to install the programs and any data files and - documentation. - - 5. You can remove the program binaries and object files from the - source code directory by typing `make clean'. To also remove the - files that `configure' created (so you can compile the package for - a different kind of computer), type `make distclean'. There is - also a `make maintainer-clean' target, but that is intended mainly - for the package's developers. If you use it, you may have to get - all sorts of other programs in order to regenerate files that came - with the distribution. - -Compilers and Options -===================== - - Some systems require unusual options for compilation or linking that -the `configure' script does not know about. Run `./configure --help' -for details on some of the pertinent environment variables. - - You can give `configure' initial values for configuration parameters -by setting variables in the command line or in the environment. Here -is an example: - - ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix - - *Note Defining Variables::, for more details. - -Compiling For Multiple Architectures -==================================== - - You can compile the package for more than one kind of computer at the -same time, by placing the object files for each architecture in their -own directory. To do this, you must use a version of `make' that -supports the `VPATH' variable, such as GNU `make'. `cd' to the -directory where you want the object files and executables to go and run -the `configure' script. `configure' automatically checks for the -source code in the directory that `configure' is in and in `..'. - - If you have to use a `make' that does not support the `VPATH' -variable, you have to compile the package for one architecture at a -time in the source code directory. After you have installed the -package for one architecture, use `make distclean' before reconfiguring -for another architecture. - -Installation Names -================== - - By default, `make install' will install the package's files in -`/usr/local/bin', `/usr/local/man', etc. You can specify an -installation prefix other than `/usr/local' by giving `configure' the -option `--prefix=PATH'. - - You can specify separate installation prefixes for -architecture-specific files and architecture-independent files. If you -give `configure' the option `--exec-prefix=PATH', the package will use -PATH as the prefix for installing programs and libraries. -Documentation and other data files will still use the regular prefix. - - In addition, if you use an unusual directory layout you can give -options like `--bindir=PATH' to specify different values for particular -kinds of files. Run `configure --help' for a list of the directories -you can set and what kinds of files go in them. - - If the package supports it, you can cause programs to be installed -with an extra prefix or suffix on their names by giving `configure' the -option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. - -Optional Features -================= - - Some packages pay attention to `--enable-FEATURE' options to -`configure', where FEATURE indicates an optional part of the package. -They may also pay attention to `--with-PACKAGE' options, where PACKAGE -is something like `gnu-as' or `x' (for the X Window System). The -`README' should mention any `--enable-' and `--with-' options that the -package recognizes. - - For packages that use the X Window System, `configure' can usually -find the X include and library files automatically, but if it doesn't, -you can use the `configure' options `--x-includes=DIR' and -`--x-libraries=DIR' to specify their locations. - -Specifying the System Type -========================== - - There may be some features `configure' cannot figure out -automatically, but needs to determine by the type of machine the package -will run on. Usually, assuming the package is built to be run on the -_same_ architectures, `configure' can figure that out, but if it prints -a message saying it cannot guess the machine type, give it the -`--build=TYPE' option. TYPE can either be a short name for the system -type, such as `sun4', or a canonical name which has the form: - - CPU-COMPANY-SYSTEM - -where SYSTEM can have one of these forms: - - OS KERNEL-OS - - See the file `config.sub' for the possible values of each field. If -`config.sub' isn't included in this package, then this package doesn't -need to know the machine type. - - If you are _building_ compiler tools for cross-compiling, you should -use the `--target=TYPE' option to select the type of system they will -produce code for. - - If you want to _use_ a cross compiler, that generates code for a -platform different from the build platform, you should specify the -"host" platform (i.e., that on which the generated programs will -eventually be run) with `--host=TYPE'. - -Sharing Defaults -================ - - If you want to set default values for `configure' scripts to share, -you can create a site shell script called `config.site' that gives -default values for variables like `CC', `cache_file', and `prefix'. -`configure' looks for `PREFIX/share/config.site' if it exists, then -`PREFIX/etc/config.site' if it exists. Or, you can set the -`CONFIG_SITE' environment variable to the location of the site script. -A warning: not all `configure' scripts look for a site script. - -Defining Variables -================== - - Variables not defined in a site shell script can be set in the -environment passed to `configure'. However, some packages may run -configure again during the build, and the customized values of these -variables may be lost. In order to avoid this problem, you should set -them in the `configure' command line, using `VAR=value'. For example: - - ./configure CC=/usr/local2/bin/gcc - -will cause the specified gcc to be used as the C compiler (unless it is -overridden in the site shell script). - -`configure' Invocation -====================== - - `configure' recognizes the following options to control how it -operates. - -`--help' -`-h' - Print a summary of the options to `configure', and exit. - -`--version' -`-V' - Print the version of Autoconf used to generate the `configure' - script, and exit. - -`--cache-file=FILE' - Enable the cache: use and save the results of the tests in FILE, - traditionally `config.cache'. FILE defaults to `/dev/null' to - disable caching. - -`--config-cache' -`-C' - Alias for `--cache-file=config.cache'. - -`--quiet' -`--silent' -`-q' - Do not print messages saying which checks are being made. To - suppress all normal output, redirect it to `/dev/null' (any error - messages will still be shown). - -`--srcdir=DIR' - Look for the package's source code in directory DIR. Usually - `configure' can determine that directory automatically. - -`configure' also accepts some other, not widely useful, options. Run -`configure --help' for more details. - diff --git a/Makefile b/Makefile deleted file mode 100644 index bcfa89dd23..0000000000 --- a/Makefile +++ /dev/null @@ -1,27 +0,0 @@ -makefiles = \ - local.mk \ - src/boost/format/local.mk \ - src/libutil/local.mk \ - src/libstore/local.mk \ - src/libmain/local.mk \ - src/libexpr/local.mk \ - src/nix-hash/local.mk \ - src/nix-store/local.mk \ - src/nix-instantiate/local.mk \ - src/nix-env/local.mk \ - src/nix-daemon/local.mk \ - src/download-via-ssh/local.mk \ - src/nix-log2xml/local.mk \ - src/bsdiff-4.3/local.mk \ - perl/local.mk \ - scripts/local.mk \ - corepkgs/local.mk \ - misc/emacs/local.mk \ - doc/manual/local.mk \ - tests/local.mk - -GLOBAL_CXXFLAGS += -std=c++0x - -include Makefile.config - -include mk/lib.mk diff --git a/Makefile.config.in b/Makefile.config.in deleted file mode 100644 index 0937483322..0000000000 --- a/Makefile.config.in +++ /dev/null @@ -1,34 +0,0 @@ -BDW_GC_LIBS = @BDW_GC_LIBS@ -CC = @CC@ -CFLAGS = @CFLAGS@ -CXX = @CXX@ -CXXFLAGS = @CXXFLAGS@ -HAVE_OPENSSL = @HAVE_OPENSSL@ -OPENSSL_LIBS = @OPENSSL_LIBS@ -PACKAGE_NAME = @PACKAGE_NAME@ -PACKAGE_VERSION = @PACKAGE_VERSION@ -bash = @bash@ -bindir = @bindir@ -bsddiff_compat_include = @bsddiff_compat_include@ -datadir = @datadir@ -datarootdir = @datarootdir@ -dblatex = @dblatex@ -docbookrng = @docbookrng@ -docbookxsl = @docbookxsl@ -docdir = @docdir@ -exec_prefix = @exec_prefix@ -includedir = @includedir@ -libdir = @libdir@ -libexecdir = @libexecdir@ -localstatedir = @localstatedir@ -mandir = @mandir@ -perl = @perl@ -perlbindings = @perlbindings@ -perllibdir = @perllibdir@ -pkglibdir = $(libdir)/$(PACKAGE_NAME) -prefix = @prefix@ -storedir = @storedir@ -sysconfdir = @sysconfdir@ -w3m = @w3m@ -xmllint = @xmllint@ -xsltproc = @xsltproc@ diff --git a/README b/README deleted file mode 100644 index 35a1f6cc08..0000000000 --- a/README +++ /dev/null @@ -1,10 +0,0 @@ -Nix is a purely functional package manager.

The - hash algorithm specified by type must - be one of "md5", "sha1" or - "sha256". - - - - - builtins.head - list - - Return the first element of a list; abort - evaluation if the argument isn’t a list or is an empty list. You - can test whether a list is empty by comparing it with - []. - - - - - import - path - - Load, parse and return the Nix expression in the - file path. If path - is a directory, the file default.nix - in that directory is loaded. Evaluation aborts if the - file doesn’t exist or contains an incorrect Nix expression. - import implements Nix’s module system: you - can put any Nix expression (such as a set or a function) in a - separate file, and use it from Nix expressions in other - files. - - A Nix expression loaded by import must - not contain any free variables (identifiers - that are not defined in the Nix expression itself and are not - built-in). Therefore, it cannot refer to variables that are in - scope at the call site. For instance, if you have a calling - expression - - -rec { - x = 123; - y = import ./foo.nix; -} - - then the following foo.nix will give an - error: - - -x + 456 - - since x is not in scope in - foo.nix. If you want x - to be available in foo.nix, you should pass - it as a function argument: - - -rec { - x = 123; - y = import ./foo.nix x; -} - - and - - -x: x + 456 - - (The function argument doesn’t have to be called - x in foo.nix; any name - would work.) - - - - - builtins.intersectAttrs - e1 e2 - - Return a set consisting of the attributes in the - set e2 that also exist in the set - e1. - - - - - builtins.isAttrs - e - - Return true if - e evaluates to a set, and - false otherwise. - - - - - builtins.isList - e - - Return true if - e evaluates to a list, and - false otherwise. - - - - - builtins.isFunction - e - - Return true if - e evaluates to a function, and - false otherwise. - - - - - builtins.isString - e - - Return true if - e evaluates to a string, and - false otherwise. - - - - - builtins.isInt - e - - Return true if - e evaluates to an int, and - false otherwise. - - - - - builtins.isBool - e - - Return true if - e evaluates to a bool, and - false otherwise. - - - - - isNull - e - - Return true if - e evaluates to null, - and false otherwise. - - This function is deprecated; - just write e == null instead. - - - - - - - builtins.length - e - - Return the length of the list - e. - - - - - builtins.lessThan - e1 e2 - - Return true if the integer - e1 is less than the integer - e2, and false - otherwise.

Each element of the list should be - a set consisting of a string-valued attribute - name specifying the name of the attribute, and - an attribute value specifying its value. - Example: - - -builtins.listToAttrs - [ { name = "foo"; value = 123; } - { name = "bar"; value = 456; } - ] - - - evaluates to - - -{ foo = 123; bar = 456; } - - - - - - - map - f list - - Apply the function f to - each element in the list list. For - example, - - -map (x: "foo" + x) [ "bar" "bla" "abc" ] - - evaluates to [ "foobar" "foobla" "fooabc" - ]. - - - - - builtins.mul - e1 e2 - - Return the product of the integers - e1 and - e2. - - - - - builtins.parseDrvName - s - - Split the string s into - a package name and version. The package name is everything up to - but not including the first dash followed by a digit, and the - version is everything following that dash. The result is returned - in a set { name, version }. Thus, - builtins.parseDrvName "nix-0.12pre12876" - returns { name = "nix"; version = "0.12pre12876"; - }. - - - - - builtins.pathExists - path - - Return true if the path - path exists, and - false otherwise. One application of this - function is to conditionally include a Nix expression containing - user configuration: - - -let - fileName = builtins.getEnv "CONFIG_FILE"; - config = - if fileName != "" && builtins.pathExists (builtins.toPath fileName) - then import (builtins.toPath fileName) - else { someSetting = false; }; # default configuration -in config.someSetting - - (Note that CONFIG_FILE must be an absolute path for - this to work.) - - - - - - - - builtins.readFile - path - - Return the contents of the file - path as a string. - - - - - removeAttrs - set list - - Remove the attributes listed in - list from - set. The attributes don’t have to - exist in set. For instance, - - -removeAttrs { x = 1; y = 2; z = 3; } [ "a" "x" "z" ] - - evaluates to { y = 2; }. - - - - - builtins.stringLength - e - - Return the length of the string - e. If e is - not a string, evaluation is aborted. - - - - - builtins.sub - e1 e2 - - Return the difference between the integers - e1 and - e2. - - - - - builtins.substring - start len - s - - Return the substring of - s from character position - start (zero-based) up to but not - including start + len. If - start is greater than the length of the - string, an empty string is returned, and if start + - len lies beyond the end of the string, only the - substring up to the end of the string is returned. - start must be - non-negative. - - - - - builtins.tail - list - - Return the second to last elements of a list; - abort evaluation if the argument isn’t a list or is an empty - list. - - - - - throw - s - - Throw an error message - s. This usually aborts Nix expression - evaluation, but in nix-env -qa and other - commands that try to evaluate a set of derivations to get - information about those derivations, a derivation that throws an - error is silently skipped (which is not the case for - abort). - - - - - builtins.toFile - name s - - Store the string s in a - file in the Nix store and return its path. The file has suffix - name. This file can be used as an - input to derivations. One application is to write builders - “inline”. For instance, the following Nix expression combines - and into one file: - - -{ stdenv, fetchurl, perl }: - -stdenv.mkDerivation { - name = "hello-2.1.1"; - - builder = builtins.toFile "builder.sh" " - source $stdenv/setup - - PATH=$perl/bin:$PATH - - tar xvfz $src - cd hello-* - ./configure --prefix=$out - make - make install - "; - - src = fetchurl { - url = http://nix.cs.uu.nl/dist/tarballs/hello-2.1.1.tar.gz; - md5 = "70c9ccf9fac07f762c24f2df2290784d"; - }; - inherit perl; -} - - - - It is even possible for one file to refer to another, e.g., - - - builder = let - configFile = builtins.toFile "foo.conf" " - # This is some dummy configuration file. - ... - "; - in builtins.toFile "builder.sh" " - source $stdenv/setup - ... - cp ${configFile} $out/etc/foo.conf - "; - - Note that ${configFile} is an antiquotation - (see ), so the result of the - expression configFile (i.e., a path like - /nix/store/m7p7jfny445k...-foo.conf) will be - spliced into the resulting string. - - It is however not allowed to have files - mutually referring to each other, like so: - - -let - foo = builtins.toFile "foo" "...${bar}..."; - bar = builtins.toFile "bar" "...${foo}..."; -in foo - - This is not allowed because it would cause a cyclic dependency in - the computation of the cryptographic hashes for - foo and bar. - - - - - builtins.toJSON e - - Return a string containing a JSON representation - of e. Strings, integers, booleans, - nulls and lists are mapped to their JSON equivalents. Sets - (except derivations) are represented as objects. Derivations are - translated to a JSON string containing the derivation’s output - path. Paths are copied to the store and represented as a JSON - string of the resulting store path. - - - - builtins.toPath s - - Convert the string value - s into a path value. The string - s must represent an absolute path - (i.e., must start with /). The path need not - exist. The resulting path is canonicalised, e.g., - builtins.toPath "//foo/xyzzy/../bar/" returns - /foo/bar. - - - - - toString e - - Convert the expression - e to a string. - e can be a string (in which case - toString is a no-op) or a path (e.g., - toString /foo/bar yields - "/foo/bar". - - - - - builtins.toXML e - - Return a string containing an XML representation - of e. The main application for - toXML is to communicate information with the - builder in a more structured format than plain environment - variables. - - - - shows an example where this is - the case. The builder is supposed to generate the configuration - file for a Jetty - servlet container. A servlet container contains a number - of servlets (*.war files) each exported under - a specific URI prefix. So the servlet configuration is a list of - sets containing the path and - war of the servlet (). This kind of information is - difficult to communicate with the normal method of passing - information through an environment variable, which just - concatenates everything together into a string (which might just - work in this case, but wouldn’t work if fields are optional or - contain lists themselves). Instead the Nix expression is - converted to an XML representation with - toXML, which is unambiguous and can easily be - processed with the appropriate tools. For instance, in the - example an XSLT stylesheet () is applied to it () to - generate the XML configuration file for the Jetty server. The XML - representation produced from by toXML is shown in . - - Note that uses the toFile built-in to write the - builder and the stylesheet “inline” in the Nix expression. The - path of the stylesheet is spliced into the builder at - xsltproc ${stylesheet} - .... - - Passing information to a builder - using <function>toXML</function> - - $out/server-conf.xml]]> - - - - - - - - - - - - - "; - - servlets = builtins.toXML []]> - - - - XML representation produced by - <function>toXML</function> - - - - - - - - - - - - - - - - - - - - - -]]> - - - - - - - - - builtins.trace - e1 e2 - - Evaluate e1 and print its - abstract syntax representation on standard error.

These can be regular files, but also entire directory - trees. Store objects can be sources (objects copied from outside of - the store), derivation outputs (objects produced by running a build - action), or derivations (files describing a build - action). - - - - -substitute - - A substitute is a command invocation stored in the - Nix database that describes how to build a store object, bypassing - normal the build mechanism (i.e., derivations). Typically, the - substitute builds the store object by downloading a pre-built - version of the store object from some server. - - - - -purity - - The assumption that equal Nix derivations when run - always produce the same output. This cannot be guaranteed in - general (e.g., a builder can rely on external inputs such as the - network or the system time) but the Nix model assumes - it. - - - - -Nix expression - - A high-level description of software packages and - compositions thereof.

For instance, - if the store object at path P contains a - reference to path Q, then Q is - in the closure of P.

Supported platforms - -Nix is currently supported on the following platforms: - - - - Linux (particularly on x86, x86_64, and - PowerPC). - - Mac OS X. - - FreeBSD (only tested on Intel). - - - - - - - -Nix is pretty portable, so it should work on most other Unix -platforms as well. - -
- - -
Installing a binary distribution - -The easiest way to install Nix is to use a binary package. -Binary packages of the latest stable release are available for Fedora, -Debian, Ubuntu, Mac OS X and various other systems from the Nix homepage. -You can also get builds of the latest development release from our -continuous -build system. - -For Fedora, RPM packages are available. These can be installed -or upgraded using rpm -U. For example, - - -$ rpm -U nix-1.0-1.i386.rpm - - - -For Debian and Ubuntu, you can download a Deb package and -install it like this: - - -$ dpkg -i nix_1.0-1_amd64.deb - - - -For other platforms, including Mac OS X (Darwin), FreeBSD and -other Linux distributions, you can download a binary tarball. It -contains Nix and all its dependencies. You should unpack it somewhere -(e.g. in /tmp), and then run the script named -install inside the binary tarball: - - -alice$ cd /tmp -alice$ tar xfj nix-1.1-x86_64-darwin.tar.bz2 -alice$ cd nix-1.1-x86_64-darwin -alice$ ./install - - -You should run this under your usual user account, -not as root. The script will invoke -sudo to create /nix if it -doesn’t already exist. If you don’t have sudo, you -should manually create /nix first as root: - - -$ mkdir /nix -$ chown alice /nix - - - - -Nix can be uninstalled using rpm -e nix or -dpkg -r nix on RPM- and Dpkg-based systems, -respectively. After this you should manually remove the Nix store and -other auxiliary data, if desired: - - -$ rm -rf /nix - - - -
- - -
Installing Nix from source - -If no binary package is available, you can download and compile -a source distribution. - -
Prerequisites - - - - GNU Make. - - A fairly recent version of GCC/G++. Version 2.95 - and higher should work. Clang will also work. - - Perl 5.8 or higher. - - pkg-config to locate - dependencies. If your distribution does not provide it, you can get - it from . - - The bzip2 compressor program and the - libbz2 library. Thus you must have bzip2 - installed, including development headers and libraries. If your - distribution does not provide these, you can obtain bzip2 from . - - The SQLite embedded database library, version 3.6.19 - or higher. If your distribution does not provide it, please install - it from . - - The Perl DBI and DBD::SQLite libraries, which are - available from CPAN if your - distribution does not provide them. - - The Boehm - garbage collector to reduce the evaluator’s memory - consumption (optional). To enable it, install - pkgconfig and the Boehm garbage collector, and - pass the flag to - configure. - - The xmllint and - xsltproc programs to build this manual and the - man-pages. These are part of the libxml2 and - libxslt packages, respectively. You also need - the DocBook - XSL stylesheets and optionally the DocBook 5.0 RELAX NG - schemas. Note that these are only required if you modify the - manual sources or when you are building from the Git - repository. - - Recent versions of Bison and Flex to build the - parser. (This is because Nix needs GLR support in Bison and - reentrancy support in Flex.) For Bison, you need version 2.6, which - can be obtained from the GNU FTP - server. For Flex, you need version 2.5.35, which is - available on SourceForge. - Slightly older versions may also work, but ancient versions like the - ubiquitous 2.5.4a won't. Note that these are only required if you - modify the parser or when you are building from the Git - repository. - - - -
- - -
Obtaining a source distribution - -The source tarball of the most recent stable release can be -downloaded from the Nix homepage. -You can also grab the most -recent development release. - -Alternatively, the most recent sources of Nix can be obtained -from its Git -repository. For example, the following command will check out -the latest revision into a directory called -nix: - - -$ git clone https://github.com/NixOS/nix - -Likewise, specific releases can be obtained from the tags of the -repository. - -
- - -
Building Nix from source - -After unpacking or checking out the Nix sources, issue the -following commands: - - -$ ./configure options... -$ make -$ make install - -Nix requires GNU Make so you may need to invoke -gmake instead. - -When building from the Git repository, these should be preceded -by the command: - - -$ ./bootstrap.sh - - - -The installation path can be specified by passing the - to -configure. The default installation directory is -/usr/local. You can change this to any location -you like. You must have write permission to the -prefix path. - -Nix keeps its store (the place where -packages are stored) in /nix/store by default. -This can be changed using -. - -It is best not to change the Nix -store from its default, since doing so makes it impossible to use -pre-built binaries from the standard Nixpkgs channels — that is, all -packages will need to be built from source. - -Nix keeps state (such as its database and log files) in -/nix/var by default. This can be changed using -. - -If you want to rebuild the documentation, pass the full path to -the DocBook RELAX NG schemas and to the DocBook XSL stylesheets using -the - -and - -options. - -

Security - -Nix has two basic security models. First, it can be used in -“single-user mode”, which is similar to what most other package -management tools do: there is a single user (typically root) who performs all package -management operations. All other users can then use the installed -packages, but they cannot perform package management operations -themselves. - -Alternatively, you can configure Nix in “multi-user mode”. In -this model, all users can perform package management operations — for -instance, every user can install software without requiring root -privileges. Nix ensures that this is secure. For instance, it’s not -possible for one user to overwrite a package used by another user with -a Trojan horse. - - -
Single-user mode - -In single-user mode, all Nix operations that access the database -in prefix/var/nix/db -or modify the Nix store in -prefix/store must be -performed under the user ID that owns those directories. This is -typically root. (If you -install from RPM packages, that’s in fact the default ownership.) -However, on single-user machines, it is often convenient to -chown those directories to your normal user account -so that you don’t have to su to root all the time. - -
- - -
Multi-user mode - -To allow a Nix store to be shared safely among multiple users, -it is important that users are not able to run builders that modify -the Nix store or database in arbitrary ways, or that interfere with -builds started by other users. If they could do so, they could -install a Trojan horse in some package and compromise the accounts of -other users. - -To prevent this, the Nix store and database are owned by some -privileged user (usually root) and builders are -executed under special user accounts (usually named -nixbld1, nixbld2, etc.). When a -unprivileged user runs a Nix command, actions that operate on the Nix -store (such as builds) are forwarded to a Nix -daemon running under the owner of the Nix store/database -that performs the operation. - -Multi-user mode has one important limitation: only -root can run nix-pull to register the availability -of pre-built binaries. However, those registrations are shared by all -users, so they still get the benefit from nix-pulls -done by root. - - -
Setting up the build users - -The build users are the special UIDs under -which builds are performed. They should all be members of the -build users group (usually called -nixbld). This group should have no other members. -The build users should not be members of any other group. - -Here is a typical /etc/group definition of -the build users group with 10 build users: - - -nixbld:!:30000:nixbld1,nixbld2,nixbld3,nixbld4,nixbld5,nixbld6,nixbld7,nixbld8,nixbld9,nixbld10 - - -In this example the nixbld group has UID 30000, but -of course it can be anything that doesn’t collide with an existing -group. - -Here is the corresponding part of -/etc/passwd: - - -nixbld1:x:30001:65534:Nix build user 1:/var/empty:/noshell -nixbld2:x:30002:65534:Nix build user 2:/var/empty:/noshell -nixbld3:x:30003:65534:Nix build user 3:/var/empty:/noshell -... -nixbld10:x:30010:65534:Nix build user 10:/var/empty:/noshell - - -The home directory of the build users should not exist or should be an -empty directory to which they do not have write access. - -The build users should have write access to the Nix store, but -they should not have the right to delete files. Thus the Nix store’s -group should be the build users group, and it should have the sticky -bit turned on (like /tmp): - - -$ chown root.nixbld /nix/store -$ chmod 1775 /nix/store - - - - -Finally, you should tell Nix to use the build users by -specifying the build users group in the build-users-group -option in the Nix configuration -file (usually /etc/nix/nix.conf): - - -build-users-group = nixbld - - - - -
- - -
Running the daemon - -The Nix daemon should be -started as follows (as root): - - -$ nix-daemon - -You’ll want to put that line somewhere in your system’s boot -scripts. - -To let unprivileged users use the daemon, they should set the -NIX_REMOTE environment -variable to daemon. So you should put a -line like - - -export NIX_REMOTE=daemon - -into the users’ login scripts. - -
- - -
Restricting access - -To limit which users can perform Nix operations, you can use the -permissions on the directory -/nix/var/nix/daemon-socket. For instance, if you -want to restrict the use of Nix to the members of a group called -nix-users, do - - -$ chgrp nix-users /nix/var/nix/daemon-socket -$ chmod ug=rwx,o= /nix/var/nix/daemon-socket - - -This way, users who are not in the nix-users group -cannot connect to the Unix domain socket -/nix/var/nix/daemon-socket/socket, so they cannot -perform Nix operations. - -
- - -
- - -
- - -
Using Nix - -To use Nix, some environment variables should be set. In -particular, PATH should contain the directories -prefix/bin and -~/.nix-profile/bin. The first directory contains -the Nix tools themselves, while ~/.nix-profile is -a symbolic link to the current user environment -(an automatically generated package consisting of symlinks to -installed packages). The simplest way to set the required environment -variables is to include the file -prefix/etc/profile.d/nix.sh -in your ~/.profile (or similar), like this: - - -source prefix/etc/profile.d/nix.sh - -

About Nix - -Nix is a purely functional package manager. -This means that it treats packages like values in purely functional -programming languages such as Haskell — they are built by functions -that don’t have side-effects, and they never change after they have -been built. Nix stores packages in the Nix -store, usually the directory -/nix/store, where each package has its own unique -subdirectory such as - - -/nix/store/nlc4z5y1hm8w9s8vm6m1f5hy962xjmp5-firefox-12.0 - - -where nlc4z5… is a unique identifier for the -package that captures all its dependencies (it’s a cryptographic hash -of the package’s build dependency graph). This enables many powerful -features. - - -Multiple versions - -You can have multiple versions or variants of a package -installed at the same time. This is especially important when -different applications have dependencies on different versions of the -same package — it prevents the “DLL hell”. Because of the hashing -scheme, different versions of a package end up in different paths in -the Nix store, so they don’t interfere with each other. - -An important consequence is that operations like upgrading or -uninstalling an application cannot break other applications, since -these operations never “destructively” update or delete files that are -used by other packages. - - - - -Complete dependencies - -Nix helps you make sure that package dependency specifications -are complete. In general, when you’re making a package for a package -management system like RPM, you have to specify for each package what -its dependencies are, but there are no guarantees that this -specification is complete. If you forget a dependency, then the -package will build and work correctly on your -machine if you have the dependency installed, but not on the end -user's machine if it's not there. - -Since Nix on the other hand doesn’t install packages in “global” -locations like /usr/bin but in package-specific -directories, the risk of incomplete dependencies is greatly reduced. -This is because tools such as compilers don’t search in per-packages -directories such as -/nix/store/5lbfaxb722zp…-openssl-0.9.8d/include, -so if a package builds correctly on your system, this is because you -specified the dependency explicitly. - -Runtime dependencies are found by scanning binaries for the hash -parts of Nix store paths (such as r8vvq9kq…). This -sounds risky, but it works extremely well. - - - - -Multi-user support - -Nix has multi-user support. This means that non-privileged -users can securely install software. Each user can have a different -profile, a set of packages in the Nix store that -appear in the user’s PATH. If a user installs a -package that another user has already installed previously, the -package won’t be built or downloaded a second time. At the same time, -it is not possible for one user to inject a Trojan horse into a -package that might be used by another user. - - - - - - -Atomic upgrades and rollbacks - -Since package management operations never overwrite packages in -the Nix store but just add new versions in different paths, they are -atomic. So during a package upgrade, there is no -time window in which the package has some files from the old version -and some files from the new version — which would be bad because a -program might well crash if it’s started during that period. - -And since package aren’t overwritten, the old versions are still -there after an upgrade. This means that you can roll -back to the old version: - - -$ nix-env --upgrade some-packages -$ nix-env --rollback - - - - - -Garbage collection - -When you uninstall a package like this… - - -$ nix-env --uninstall firefox - - -the package isn’t deleted from the system right away (after all, you -might want to do a rollback, or it might be in the profiles of other -users). Instead, unused packages can be deleted safely by running the -garbage collector: - - -$ nix-collect-garbage - - -This deletes all packages that aren’t in use by any user profile or by -a currently running program. - - - - -Functional package language - -Packages are built from Nix expressions, -which is a simple functional language. A Nix expression describes -everything that goes into a package build action (a “derivation”): -other packages, sources, the build script, environment variables for -the build script, etc. Nix tries very hard to ensure that Nix -expressions are deterministic: building a Nix -expression twice should yield the same result. - -Because it’s a functional language, it’s easy to support -building variants of a package: turn the Nix expression into a -function and call it any number of times with the appropriate -arguments. Due to the hashing scheme, variants don’t conflict with -each other in the Nix store. - - - - -Transparent source/binary deployment - -Nix expressions generally describe how to build a package from -source, so an installation action like - - -$ nix-env --install firefox - - -could cause quite a bit of build activity, as not -only Firefox but also all its dependencies (all the way up to the C -library and the compiler) would have to built, at least if they are -not already in the Nix store. This is a source deployment -model. For most users, building from source is not very -pleasant as it takes far too long. However, Nix can automatically -skip building from source and download a pre-built binary instead if -it knows about it. Nix channels provide Nix -expressions along with pre-built binaries. - - - - - - -Binary patching - -In addition to downloading binaries automatically if they’re -available, Nix can download binary deltas that patch an existing -package in the Nix store into a new version.

This is -done by treating all the static bits of a service (such as software -packages, configuration files, control scripts, static web pages, -etc.) as “packages” that can be built by Nix expressions. As a -result, all the features above apply to services as well: for -instance, you can roll back a web server configuration if a -configuration change turns out to be undesirable, you can easily have -multiple instances of a service (e.g., a test and production server), -and because the whole service is built in a purely functional way from -a Nix expression, it is repeatable so you can easily reproduce the -service on another machine. - - - - - - -Portability - -Nix should run on most Unix systems, including Linux, FreeBSD and -Mac OS X. - - - - -NixOS - -NixOS is a Linux distribution based on Nix. It uses Nix not -just for package management but also to manage the system -configuration (e.g., to build configuration files in -/etc). This means, among other things, that it’s -possible to easily roll back the entire configuration of the system to -an earlier state. Also, users can install software without root -privileges.

About us - -Nix was originally developed at the Department of Information and -Computing Sciences, Utrecht University by the TraCE -project (2003-2008). The project was funded by the Software -Engineering Research Program Jacquard to improve the -support for variability in software systems. Further funding was -provided by the NIRICT LaQuSo Build Farm project. Development is -currently supported by LogicBlox. - -

More information - -Some background information on Nix can be found in a number of -papers. The ICSE 2004 paper Imposing -a Memory Management Discipline on Software Deployment -discusses the hashing mechanism used to ensure reliable dependency -identification and non-interference between different versions and -variants of packages. The LISA 2004 paper Nix: -A Safe and Policy-Free System for Software Deployment -gives a more general discussion of Nix from a system-administration -perspective. The CBSE 2005 paper Efficient -Upgrading in a Purely Functional Component Deployment Model - is about transparent patch deployment in Nix. The SCM-12 -paper -Service Configuration Management shows how services (e.g., -web servers) can be deployed and managed through Nix. An overview of -NixOS is given in the JFP article NixOS: -A Purely Functional Linux Distribution. The Nix homepage -has an up-to-date -list of Nix-related papers. - -Nix is the subject of Eelco Dolstra’s PhD thesis The -Purely Functional Software Deployment Model, which -contains most of the papers listed above. - -Nix has a homepage at . - -

To just -unconditionally replace Subversion with whatever version is in the Nix -expressions, use -i instead of --u; -i will remove -whatever version is already installed. - -You can also upgrade all packages for which there are newer -versions: - - -$ nix-env -f nixpkgs-version -u '*' - - - -Sometimes it’s useful to be able to ask what -nix-env would do, without actually doing it. For -instance, to find out what packages would be upgraded by -nix-env -u '*', you can do - - -$ nix-env ... -u '*' --dry-run -(dry run; not doing anything) -upgrading `libxslt-1.1.0' to `libxslt-1.1.10' -upgrading `graphviz-1.10' to `graphviz-1.12' -upgrading `coreutils-5.0' to `coreutils-5.2.1' - - - -
- - -
Profiles - -Profiles and user environments are Nix’s mechanism for -implementing the ability to allow different users to have different -configurations, and to do atomic upgrades and rollbacks. To -understand how they work, it’s useful to know a bit about how Nix -works. In Nix, packages are stored in unique locations in the -Nix store (typically, -/nix/store). For instance, a particular version -of the Subversion package might be stored in a directory -/nix/store/dpmvp969yhdqs7lm2r1a3gng7pyq6vy4-subversion-1.1.3/, -while another version might be stored in -/nix/store/5mq2jcn36ldlmh93yj1n8s9c95pj7c5s-subversion-1.1.2. -The long strings prefixed to the directory names are cryptographic -hashes160-bit truncations of SHA-256 hashes encoded in -a base-32 notation, to be precise. of -all inputs involved in building the package — -sources, dependencies, compiler flags, and so on. So if two -packages differ in any way, they end up in different locations in -the file system, so they don’t interfere with each other. shows a part of a typical Nix -store. - -
User environments - - - - - -
- -Of course, you wouldn’t want to type - - -$ /nix/store/dpmvp969yhdq...-subversion-1.1.3/bin/svn - -every time you want to run Subversion. Of course we could set up the -PATH environment variable to include the -bin directory of every package we want to use, -but this is not very convenient since changing PATH -doesn’t take effect for already existing processes. The solution Nix -uses is to create directory trees of symlinks to -activated packages. These are called -user environments and they are packages -themselves (though automatically generated by -nix-env), so they too reside in the Nix store. For -instance, in the user -environment /nix/store/0c1p5z4kda11...-user-env -contains a symlink to just Subversion 1.1.2 (arrows in the figure -indicate symlinks). This would be what we would obtain if we had done - - -$ nix-env -i subversion - -on a set of Nix expressions that contained Subversion 1.1.2. - -This doesn’t in itself solve the problem, of course; you -wouldn’t want to type -/nix/store/0c1p5z4kda11...-user-env/bin/svn -either. That’s why there are symlinks outside of the store that point -to the user environments in the store; for instance, the symlinks -default-42-link and -default-43-link in the example. These are called -generations since every time you perform a -nix-env operation, a new user environment is -generated based on the current one. For instance, generation 43 was -created from generation 42 when we did - - -$ nix-env -i subversion mozilla - -on a set of Nix expressions that contained Mozilla and a new version -of Subversion. - -Generations are grouped together into -profiles so that different users don’t interfere -with each other if they don’t want to. For example: - - -$ ls -l /nix/var/nix/profiles/ -... -lrwxrwxrwx 1 eelco ... default-42-link -> /nix/store/0c1p5z4kda11...-user-env -lrwxrwxrwx 1 eelco ... default-43-link -> /nix/store/3aw2pdyx2jfc...-user-env -lrwxrwxrwx 1 eelco ... default -> default-43-link - -This shows a profile called default. The file -default itself is actually a symlink that points -to the current generation. When we do a nix-env -operation, a new user environment and generation link are created -based on the current one, and finally the default -symlink is made to point at the new generation. This last step is -atomic on Unix, which explains how we can do atomic upgrades. (Note -that the building/installing of new packages doesn’t interfere in -any way with old packages, since they are stored in different -locations in the Nix store.) - -If you find that you want to undo a nix-env -operation, you can just do - - -$ nix-env --rollback - -which will just make the current generation link point at the previous -link. E.g., default would be made to point at -default-42-link. You can also switch to a -specific generation: - - -$ nix-env --switch-generation 43 - -which in this example would roll forward to generation 43 again. You -can also see all available generations: - - -$ nix-env --list-generations - -Actually, there is another level of indirection not shown in the -figure above. You generally wouldn’t have -/nix/var/nix/profiles/some-profile/bin -in your PATH. Rather, there is a symlink -~/.nix-profile that points to your current -profile. This means that you should put -~/.nix-profile/bin in your PATH -(and indeed, that’s what the initialisation script -/nix/etc/profile.d/nix.sh does). This makes it -easier to switch to a different profile. You can do that using the -command nix-env --switch-profile: - - -$ nix-env --switch-profile /nix/var/nix/profiles/my-profile - -$ nix-env --switch-profile /nix/var/nix/profiles/default - -These commands switch to the my-profile and -default profile, respectively. If the profile doesn’t exist, it will -be created automatically. You should be careful about storing a -profile in another location than the profiles -directory, since otherwise it might not be used as a root of the -garbage collector (see ). - -All nix-env operations work on the profile -pointed to by ~/.nix-profile, but you can override -this using the option (abbreviation -): - - -$ nix-env -p /nix/var/nix/profiles/other-profile -i subversion - -This will not change the -~/.nix-profile symlink. - -
- - -
Garbage collection - -nix-env operations such as upgrades -() and uninstall () never -actually delete packages from the system. All they do (as shown -above) is to create a new user environment that no longer contains -symlinks to the “deleted” packages. - -Of course, since disk space is not infinite, unused packages -should be removed at some point. You can do this by running the Nix -garbage collector. It will remove from the Nix store any package -not used (directly or indirectly) by any generation of any -profile. - -Note however that as long as old generations reference a -package, it will not be deleted. After all, we wouldn’t be able to -do a rollback otherwise. So in order for garbage collection to be -effective, you should also delete (some) old generations. Of course, -this should only be done if you are certain that you will not need to -roll back. - -To delete all old (non-current) generations of your current -profile: - - -$ nix-env --delete-generations old - -Instead of old you can also specify a list of -generations, e.g., - - -$ nix-env --delete-generations 10 11 14 - - - -After removing appropriate old generations you can run the -garbage collector as follows: - - -$ nix-store --gc - -If you are feeling uncertain, you can also first view what files would -be deleted: - - -$ nix-store --gc --print-dead - -Likewise, the option will show the paths -that won’t be deleted. - -There is also a convenient little utility -nix-collect-garbage, which when invoked with the - () switch deletes all -old generations of all profiles in -/nix/var/nix/profiles. So - - -$ nix-collect-garbage -d - -is a quick and easy way to clean up your system. - - - - -
Garbage collector roots - -The roots of the garbage collector are all store paths to which -there are symlinks in the directory -prefix/nix/var/nix/gcroots. -For instance, the following command makes the path -/nix/store/d718ef...-foo a root of the collector: - - -$ ln -s /nix/store/d718ef...-foo /nix/var/nix/gcroots/bar - -That is, after this command, the garbage collector will not remove -/nix/store/d718ef...-foo or any of its -dependencies. - -Subdirectories of -prefix/nix/var/nix/gcroots -are also searched for symlinks. Symlinks to non-store paths are -followed and searched for roots, but symlinks to non-store paths -inside the paths reached in that way are not -followed to prevent infinite recursion. - -
- -
- - -
Channels - -If you want to stay up to date with a set of packages, it’s not -very convenient to manually download the latest set of Nix expressions -for those packages, use nix-pull to register -pre-built binaries (if available), and upgrade using -nix-env. Fortunately, there’s a better way: -Nix channels. - -A Nix channel is just a URL that points to a place that contains -a set of Nix expressions and a manifest. Using the command nix-channel you -can automatically stay up to date with whatever is available at that -URL. - -You can “subscribe” to a channel using -nix-channel --add, e.g., - - -$ nix-channel --add http://nixos.org/channels/nixpkgs-unstable - -subscribes you to a channel that always contains that latest version -of the Nix Packages collection. (Instead of -nixpkgs-unstable you could also subscribe to -nixpkgs-stable, which should have a higher level of -stability, but right now is just outdated.) Subscribing really just -means that the URL is added to the file -~/.nix-channels. Right now there is no command -to “unsubscribe”; you should just edit that file manually -and delete the offending URL. - -To obtain the latest Nix expressions available in a channel, do - - -$ nix-channel --update - -This downloads the Nix expressions in every channel (downloaded from -url/nixexprs.tar.bz2) -and registers any available pre-built binaries in every channel -(by nix-pulling -url/MANIFEST). It also -makes the union of each channel’s Nix expressions the default for -nix-env operations. Consequently, you can then say - - -$ nix-env -u '*' - -to upgrade all packages in your profile to the latest versions -available in the subscribed channels. - -
- - -
One-click installs - -Often, when you want to install a specific package (e.g., from -the Nix -Packages collection), subscribing to a channel is a bit -cumbersome. And channels don’t help you at all if you want to install -an older version of a package than the one provided by the current -contents of the channel, or a package that has been removed from the -channel. That’s when one-click installs come in -handy: you can just go to the web page that contains the package, -click on it, and it will be installed with all the necessary -dependencies. - -For instance, you can go to and click on any link for the individual packages for your -platform. The first time you do this, your browser will ask what to -do with application/nix-package files. You should -open them with /nix/bin/nix-install-package. -This will open a window that asks you to confirm that you want to -install the package. When you answer Y, the -package and all its dependencies will be installed. This is a binary -deployment mechanism — you get packages pre-compiled for the selected -platform type. - -You can also install application/nix-package -files from the command line directly. See for details. - -
- - -
Sharing packages between machines - -Sometimes you want to copy a package from one machine to -another. Or, you want to install some packages and you know that -another machine already has some or all of those packages or their -dependencies. In that case there are mechanisms to quickly copy -packages between machines. - -The command nix-copy-closure copies a Nix -store path along with all its dependencies to or from another machine -via the SSH protocol. It doesn’t copy store paths that are already -present on the target machine. For example, the following command -copies Firefox with all its dependencies: - - -$ nix-copy-closure --to alice@itchy.example.org $(type -p firefox) - -See for details. - -With nix-store ---export and nix-store --import you can -write the closure of a store path (that is, the path and all its -dependencies) to a file, and then unpack that file into another Nix -store. For example, - - -$ nix-store --export $(nix-store -qR $(type -p firefox)) > firefox.closure - -writes the closure of Firefox to a file. You can then copy this file -to another machine and install the closure: - - -$ nix-store --import < firefox.closure - -Any store paths in the closure that are already present in the target -store are ignored. It is also possible to pipe the export into -another command, e.g. to copy and install a closure directly to/on -another machine: - - -$ nix-store --export $(nix-store -qR $(type -p firefox)) | bzip2 | \ - ssh alice@itchy.example.org "bunzip2 | nix-store --import" - -But note that nix-copy-closure is generally more -efficient in this example because it only copies paths that are not -already present in the target Nix store. - -Finally, if you can mount the Nix store of a remote machine in -your local filesystem, Nix can copy paths from the remote Nix store to -the local Nix store on demand. For instance, -suppose that you mount a remote machine containing a Nix store via -sshfs: - - -$ sshfs alice@itchy.example.org:/ /mnt - -You should then set the NIX_OTHER_STORES environment -variable to tell Nix about this remote Nix store: - - -$ export NIX_OTHER_STORES=/mnt/nix - -Then if you do any Nix operation, e.g. - - -$ nix-env -i firefox - -and Nix has to build a path that it sees is already present in -/mnt/nix, then it will just copy from there -instead of building it from source. - - -

- -Nix Release Notes - - - - -
Release 1.7 (TBA) - -In addition to the usual bug fixes, this release has the -following new features: - - - - - Antiquotation is now allowed inside of quoted attribute - names (e.g. set."${foo}"). In the case where - the attribute name is just a single antiquotation, the quotes can - be dropped (e.g. the above example can be written - set.${foo}). If an attribute name inside of a - set declaration evaluates to null (e.g. - { ${null} = false; }), then that attribute is - not added to the set. - - - - Experimental support for cryptographically signed binary - caches. See the - commit for details. - - - - An experimental new substituter, - download-via-ssh, that fetches binaries from - remote machines via SSH. Specifying the flags --option - use-ssh-substituter true --option ssh-substituter-hosts - user@hostname will cause Nix - to download binaries from the specified machine, if it has - them. - - - - nix-store -r and - nix-build have a new flag, - , that builds a previously built - derivation again, and prints an error message if the output is not - exactly the same. This helps to verify whether a derivation is - truly deterministic. For example: - - -$ nix-build '<nixpkgs>' -A patchelf -… -$ nix-build '<nixpkgs>' -A patchelf --check -… -error: derivation `/nix/store/1ipvxs…-patchelf-0.6' may not be deterministic: - hash mismatch in output `/nix/store/4pc1dm…-patchelf-0.6.drv' - - - - - - - - The nix-instantiate flags - and - have been renamed to and - , respectively. - - - - nix-instantiate, - nix-build and nix-shell now - have a flag (or ) that - allows you to specify the expression to be evaluated as a command - line argument. For instance, nix-instantiate --eval -E - '1 + 2' will print 3. - - - - nix-shell improvements: - - - - - It has a new flag, (or - ), that sets up a build environment - containing the specified packages from Nixpkgs. For example, - the command - - -$ nix-shell -p sqlite xorg.libX11 hello - - - will start a shell in which the given packages are - present. - - - - It now uses shell.nix as the - default expression, falling back to - default.nix if the former doesn’t - exist. This makes it convenient to have a - shell.nix in your project to set up a - nice development environment. - - - - It evaluates the derivation attribute - shellHook, if set. Since - stdenv does not normally execute this hook, - it allows you to do nix-shell-specific - setup. - - - - It preserves the user’s timezone setting. - - - - - - - - In chroots, Nix now sets up a /dev - containing only a minimal set of devices (such as - /dev/null). Note that it only does this if - you don’t have /dev - listed in your setting; - otherwise, it will bind-mount the /dev from - outside the chroot. - - Similarly, if you don’t have /dev/pts listed - in , Nix will mount a private - devpts filesystem on the chroot’s - /dev/pts. - - - - - New built-in function: builtins.toJSON, - which returns a JSON representation of a value. - - - - nix-env -q has a new flag - to print a JSON representation of the - installed or available packages. - - - - nix-env now supports meta attributes with - more complex values, such as attribute sets. - - - - The flag now allows attribute names with - dots in them, e.g. - - -$ nix-instantiate --eval '<nixos>' -A 'config.systemd.units."nscd.service".text' - - - - - - - The option to - nix-store --gc now accepts a unit - specifier. For example, nix-store --gc --max-freed - 1G will free up to 1 gigabyte of disk space. - - - - Nix now heuristically detects whether a build failure was - due to a disk-full condition. In that case, the build is not - flagged as “permanently failed”. This is mostly useful for Hydra, - which needs to distinguish between permanent and transient build - failures. - - - - There is a new symbol __curPos that - expands to an attribute set containing its file name and line and - column numbers, e.g. { file = "foo.nix"; line = 10; - column = 5; }. There also is a new builtin function, - unsafeGetAttrPos, that returns the position of - an attribute. This is used by Nixpkgs to provide location - information in error messages, e.g. - - -$ nix-build '<nixpkgs>' -A libreoffice --argstr system x86_64-darwin -error: the package ‘libreoffice-4.0.5.2’ in ‘.../applications/office/libreoffice/default.nix:263’ - is not supported on ‘x86_64-darwin’ - - - - - - - The garbage collector is now more concurrent with other Nix - processes because it releases certain locks earlier. - - - - The binary tarball installer has been improved. You can now - install Nix by running: - - -$ bash <(curl https://nixos.org/nix/install) - - - - - - - The command nix-setuid-helper is - gone. - - - - Nix no longer uses Automake, but instead has a - non-recursive, GNU Make-based build system. - - - - All installed libraries now have the prefix - libnix. In particular, this gets rid of - libutil, which could clash with libraries with - the same name from other packages. - - - - -
- - - - -
Release 1.6.1 (October 28, 2013) - -This is primarily a bug fix release. Changes of interest -are: - - - - - Nix 1.6 accidentally changed the semantics of antiquoted - paths in strings, such as "${/foo}/bar". This - release reverts to the Nix 1.5.3 behaviour. - - - - Previously, Nix optimised expressions such as - "${expr}" to - expr. Thus it neither checked whether - expr could be coerced to a string, nor - applied such coercions. This meant that - "${123}" evaluatued to 123, - and "${./foo}" evaluated to - ./foo (even though - "${./foo} " evaluates to - "/nix/store/hash-foo "). - Nix now checks the type of antiquoted expressions and - applies coercions. - - - - Nix now shows the exact position of undefined variables. In - particular, undefined variable errors in a with - previously didn't show any position - information, so this makes it a lot easier to fix such - errors. - - - - Undefined variables are now treated consistently. - Previously, the tryEval function would catch - undefined variables inside a with but not - outside. Now tryEval never catches undefined - variables. - - - - Bash completion in nix-shell now works - correctly. - - - - Stack traces are less verbose: they no longer show calls to - builtin functions and only show a single line for each derivation - on the call stack. - - - - New built-in function: builtins.typeOf, - which returns the type of its argument as a string. - - - - -
- - - - -
Release 1.6 (September 10, 2013) - -In addition to the usual bug fixes, this release has several new -features: - - - - - The command nix-build --run-env has been - renamed to nix-shell. - - - - nix-shell now sources - $stdenv/setup inside the - interactive shell, rather than in a parent shell. This ensures - that shell functions defined by stdenv can be - used in the interactive shell. - - - - nix-shell has a new flag - to clear the environment, so you get an - environment that more closely corresponds to the “real” Nix build. - - - - - nix-shell now sets the shell prompt - (PS1) to ensure that Nix shells are distinguishable - from your regular shells. - - - - nix-env no longer requires a - * argument to match all packages, so - nix-env -qa is equivalent to nix-env - -qa '*'. - - - - nix-env -i has a new flag - () to remove all - previous packages from the profile. This makes it easier to do - declarative package management similar to NixOS’s - . For instance, if you - have a specification my-packages.nix like this: - - -with import <nixpkgs> {}; -[ thunderbird - geeqie - ... -] - - - then after any change to this file, you can run: - - -$ nix-env -f my-packages.nix -ir - - - to update your profile to match the specification. - - - - The ‘with’ language construct is now more - lazy. It only evaluates its argument if a variable might actually - refer to an attribute in the argument. For instance, this now - works: - - -let - pkgs = with pkgs; { foo = "old"; bar = foo; } // overrides; - overrides = { foo = "new"; }; -in pkgs.bar - - - This evaluates to "new", while previously it - gave an “infinite recursion” error. - - - - Nix now has proper integer arithmetic operators. For - instance, you can write x + y instead of - builtins.add x y, or x < - y instead of builtins.lessThan x y. - The comparison operators also work on strings. - - - - On 64-bit systems, Nix integers are now 64 bits rather than - 32 bits. - - - - When using the Nix daemon, the nix-daemon - worker process now runs on the same CPU as the client, on systems - that support setting CPU affinity. This gives a significant speedup - on some systems. - - - - If a stack overflow occurs in the Nix evaluator, you now get - a proper error message (rather than “Segmentation fault”) on some - systems. - - - - In addition to directories, you can now bind-mount regular - files in chroots through the (now misnamed) option - . - - - - -This release has contributions from Domen Kožar, Eelco Dolstra, -Florian Friesdorf, Gergely Risko, Ivan Kozik, Ludovic Courtès and Shea -Levy. - -
- - - - -
Release 1.5.3 (June 17, 2013) - -This is primarily a bug fix release. The following changes are -noteworthy: - - - - - Yet another security bug involving hard links to files - outside the store was fixed. This bug only affected multi-user - installations that do not have hard link restrictions - enabled. (NixOS is thus not vulnerable.) - - - - The default binary cache URL has changed from - http://nixos.org/binary-cache to - http://cache.nixos.org. The latter is hosted on Amazon - CloudFront (courtesy of LogicBlox) and - should provide better performance for users in both Europe and - North America. - - - - The binary cache substituter now prints a warning message if - fetching information from the cache takes more than five seconds. - Thus network or server problems no longer make Nix appear to just - hang. - - - - Stack traces now show function names, e.g. - -while evaluating `concatMapStrings' at `.../nixpkgs/pkgs/lib/strings.nix:18:25': - - Also, if a function is called with an unexpected argument, Nix - now shows the name of the argument. - - - - - -
- - - - -
Release 1.5.2 (May 13, 2013) - -This is primarily a bug fix release. It has contributions from -Eelco Dolstra, Lluís Batlle i Rossell and Shea Levy. - -
- - - - -
Release 1.5.1 (February 28, 2013) - -The bug fix to the bug fix had a bug itself, of course. But -this time it will work for sure! - -
- - - - -
Release 1.5 (February 27, 2013) - -This is a brown paper bag release to fix a regression introduced -by the hard link security fix in 1.4. - -
- - - - -
Release 1.4 (February 26, 2013) - -This release fixes a security bug in multi-user operation. It -was possible for derivations to cause the mode of files outside of the -Nix store to be changed to 444 (read-only but world-readable) by -creating hard links to those files (details). - -There are also the following improvements: - - - - New built-in function: - builtins.hashString. - - Build logs are now stored in - /nix/var/log/nix/drvs/XX/, - where XX is the first two characters of - the derivation. This is useful on machines that keep a lot of build - logs (such as Hydra servers). - - The function corepkgs/fetchurl - can now make the downloaded file executable. This will allow - getting rid of all bootstrap binaries in the Nixpkgs source - tree. - - Language change: The expression "${./path} - ..." now evaluates to a string instead of a - path. - - - -
- - - - -
Release 1.3 (January 4, 2013) - -This is primarily a bug fix release. When this version is first -run on Linux, it removes any immutable bits from the Nix store and -increases the schema version of the Nix store. (The previous release -removed support for setting the immutable bit; this release clears any -remaining immutable bits to make certain operations more -efficient.) - -This release has contributions from Eelco Dolstra and Stuart -Pernsteiner. - -
- - - - -
Release 1.2 (December 6, 2012) - -This release has the following improvements and changes: - - - - - Nix has a new binary substituter mechanism: the - binary cache. A binary cache contains - pre-built binaries of Nix packages. Whenever Nix wants to build a - missing Nix store path, it will check a set of binary caches to - see if any of them has a pre-built binary of that path. The - configuration setting contains a - list of URLs of binary caches. For instance, doing - -$ nix-env -i thunderbird --option binary-caches http://cache.nixos.org - - will install Thunderbird and its dependencies, using the available - pre-built binaries in http://cache.nixos.org. - The main advantage over the old “manifest”-based method of getting - pre-built binaries is that you don’t have to worry about your - manifest being in sync with the Nix expressions you’re installing - from; i.e., you don’t need to run nix-pull to - update your manifest. It’s also more scalable because you don’t - need to redownload a giant manifest file every time. - - - A Nix channel can provide a binary cache URL that will be - used automatically if you subscribe to that channel. If you use - the Nixpkgs or NixOS channels - (http://nixos.org/channels) you automatically get the - cache http://cache.nixos.org. - - Binary caches are created using nix-push. - For details on the operation and format of binary caches, see the - nix-push manpage. More details are provided in - this - nix-dev posting. - - - - Multiple output support should now be usable. A derivation - can declare that it wants to produce multiple store paths by - saying something like - -outputs = [ "lib" "headers" "doc" ]; - - This will cause Nix to pass the intended store path of each output - to the builder through the environment variables - lib, headers and - doc. Other packages can refer to a specific - output by referring to - pkg.output, - e.g. - -buildInputs = [ pkg.lib pkg.headers ]; - - If you install a package with multiple outputs using - nix-env, each output path will be symlinked - into the user environment. - - - - Dashes are now valid as part of identifiers and attribute - names. - - - - The new operation nix-store --repair-path - allows corrupted or missing store paths to be repaired by - redownloading them. nix-store --verify --check-contents - --repair will scan and repair all paths in the Nix - store. Similarly, nix-env, - nix-build, nix-instantiate - and nix-store --realise have a - flag to detect and fix bad paths by - rebuilding or redownloading them. - - - - Nix no longer sets the immutable bit on files in the Nix - store. Instead, the recommended way to guard the Nix store - against accidental modification on Linux is to make it a read-only - bind mount, like this: - - -$ mount --bind /nix/store /nix/store -$ mount -o remount,ro,bind /nix/store - - - Nix will automatically make /nix/store - writable as needed (using a private mount namespace) to allow - modifications. - - - - Store optimisation (replacing identical files in the store - with hard links) can now be done automatically every time a path - is added to the store. This is enabled by setting the - configuration option auto-optimise-store to - true (disabled by default). - - - - Nix now supports xz compression for NARs - in addition to bzip2. It compresses about 30% - better on typical archives and decompresses about twice as - fast. - - - - Basic Nix expression evaluation profiling: setting the - environment variable NIX_COUNT_CALLS to - 1 will cause Nix to print how many times each - primop or function was executed. - - - - New primops: concatLists, - elem, elemAt and - filter. - - - - The command nix-copy-closure has a new - flag () to - download missing paths on the target machine using the substitute - mechanism. - - - - The command nix-worker has been renamed - to nix-daemon. Support for running the Nix - worker in “slave” mode has been removed. - - - - The flag of every Nix command now - invokes man. - - - - Chroot builds are now supported on systemd machines. - - - - -This release has contributions from Eelco Dolstra, Florian -Friesdorf, Mats Erik Andersson and Shea Levy. - -
- - - - -
Release 1.1 (July 18, 2012) - -This release has the following improvements: - - - - - On Linux, when doing a chroot build, Nix now uses various - namespace features provided by the Linux kernel to improve - build isolation. Namely: - - The private network namespace ensures that - builders cannot talk to the outside world (or vice versa): each - build only sees a private loopback interface. This also means - that two concurrent builds can listen on the same port (e.g. as - part of a test) without conflicting with each - other. - The PID namespace causes each build to start as - PID 1. Processes outside of the chroot are not visible to those - on the inside. On the other hand, processes inside the chroot - are visible from the outside (though with - different PIDs). - The IPC namespace prevents the builder from - communicating with outside processes using SysV IPC mechanisms - (shared memory, message queues, semaphores). It also ensures - that all IPC objects are destroyed when the builder - exits. - The UTS namespace ensures that builders see a - hostname of localhost rather than the actual - hostname. - The private mount namespace was already used by - Nix to ensure that the bind-mounts used to set up the chroot are - cleaned up automatically. - - - - - - Build logs are now compressed using - bzip2. The command nix-store - -l decompresses them on the fly. This can be disabled - by setting the option build-compress-log to - false. - - - - The creation of build logs in - /nix/var/log/nix/drvs can be disabled by - setting the new option build-keep-log to - false. This is useful, for instance, for Hydra - build machines. - - - - Nix now reserves some space in - /nix/var/nix/db/reserved to ensure that the - garbage collector can run successfully if the disk is full. This - is necessary because SQLite transactions fail if the disk is - full. - - - - Added a basic fetchurl function. This - is not intended to replace the fetchurl in - Nixpkgs, but is useful for bootstrapping; e.g., it will allow us - to get rid of the bootstrap binaries in the Nixpkgs source tree - and download them instead. You can use it by doing - import <nix/fetchurl.nix> { url = - url; sha256 = - "hash"; }. (Shea Levy) - - - - Improved RPM spec file. (Michel Alexandre Salim) - - - - Support for on-demand socket-based activation in the Nix - daemon with systemd. - - - - Added a manpage for - nix.conf5. - - - - When using the Nix daemon, the flag in - nix-env -qa is now much faster. - - - - -
- - - - -
Release 1.0 (May 11, 2012) - -There have been numerous improvements and bug fixes since the -previous release. Here are the most significant: - - - - - Nix can now optionally use the Boehm garbage collector. - This significantly reduces the Nix evaluator’s memory footprint, - especially when evaluating large NixOS system configurations. It - can be enabled using the configure - option. - - - - Nix now uses SQLite for its database. This is faster and - more flexible than the old ad hoc format. - SQLite is also used to cache the manifests in - /nix/var/nix/manifests, resulting in a - significant speedup. - - - - Nix now has an search path for expressions. The search path - is set using the environment variable NIX_PATH and - the command line option. In Nix expressions, - paths between angle brackets are used to specify files that must - be looked up in the search path. For instance, the expression - <nixpkgs/default.nix> looks for a file - nixpkgs/default.nix relative to every element - in the search path. - - - - The new command nix-build --run-env - builds all dependencies of a derivation, then starts a shell in an - environment containing all variables from the derivation. This is - useful for reproducing the environment of a derivation for - development. - - - - The new command nix-store --verify-path - verifies that the contents of a store path have not - changed. - - - - The new command nix-store --print-env - prints out the environment of a derivation in a format that can be - evaluated by a shell. - - - - Attribute names can now be arbitrary strings. For instance, - you can write { "foo-1.2" = …; "bla bla" = …; }."bla - bla". - - - - Attribute selection can now provide a default value using - the or operator. For instance, the expression - x.y.z or e evaluates to the attribute - x.y.z if it exists, and e - otherwise. - - - - The right-hand side of the ? operator can - now be an attribute path, e.g., attrs ? - a.b.c. - - - - On Linux, Nix will now make files in the Nix store immutable - on filesystems that support it. This prevents accidental - modification of files in the store by the root user. - - - - Nix has preliminary support for derivations with multiple - outputs. This is useful because it allows parts of a package to - be deployed and garbage-collected separately. For instance, - development parts of a package such as header files or static - libraries would typically not be part of the closure of an - application, resulting in reduced disk usage and installation - time. - - - - The Nix store garbage collector is faster and holds the - global lock for a shorter amount of time. - - - - The option (corresponding to the - configuration setting build-timeout) allows you - to set an absolute timeout on builds — if a build runs for more than - the given number of seconds, it is terminated. This is useful for - recovering automatically from builds that are stuck in an infinite - loop but keep producing output, and for which - --max-silent-time is ineffective. - - - - Nix development has moved to GitHub (). - - - - -
- - - - -
Release 0.16 (August 17, 2010) - -This release has the following improvements: - - - - - The Nix expression evaluator is now much faster in most - cases: typically, 3 - to 8 times compared to the old implementation. It also - uses less memory. It no longer depends on the ATerm - library. - - - - - Support for configurable parallelism inside builders. Build - scripts have always had the ability to perform multiple build - actions in parallel (for instance, by running make -j - 2), but this was not desirable because the number of - actions to be performed in parallel was not configurable. Nix - now has an option as well as a configuration - setting build-cores = - N that causes the - environment variable NIX_BUILD_CORES to be set to - N when the builder is invoked. The - builder can use this at its discretion to perform a parallel - build, e.g., by calling make -j - N. In Nixpkgs, this can be - enabled on a per-package basis by setting the derivation - attribute enableParallelBuilding to - true. - - - - - nix-store -q now supports XML output - through the flag. - - - - Several bug fixes. - - - - -
- - - - -
Release 0.15 (March 17, 2010) - -This is a bug-fix release. Among other things, it fixes -building on Mac OS X (Snow Leopard), and improves the contents of -/etc/passwd and /etc/group -in chroot builds. - -
- - - - -
Release 0.14 (February 4, 2010) - -This release has the following improvements: - - - - - The garbage collector now starts deleting garbage much - faster than before. It no longer determines liveness of all paths - in the store, but does so on demand. - - - - Added a new operation, nix-store --query - --roots, that shows the garbage collector roots that - directly or indirectly point to the given store paths. - - - - Removed support for converting Berkeley DB-based Nix - databases to the new schema. - - - - Removed the and - garbage collector options. They were - not very useful in practice. - - - - On Windows, Nix now requires Cygwin 1.7.x. - - - - A few bug fixes. - - - - -
- - - - -
Release 0.13 (November 5, -2009) - -This is primarily a bug fix release. It has some new -features: - - - - - Syntactic sugar for writing nested attribute sets. Instead of - - -{ - foo = { - bar = 123; - xyzzy = true; - }; - a = { b = { c = "d"; }; }; -} - - - you can write - - -{ - foo.bar = 123; - foo.xyzzy = true; - a.b.c = "d"; -} - - - This is useful, for instance, in NixOS configuration files. - - - - - Support for Nix channels generated by Hydra, the Nix-based - continuous build system. (Hydra generates NAR archives on the - fly, so the size and hash of these archives isn’t known in - advance.) - - - - Support i686-linux builds directly on - x86_64-linux Nix installations. This is - implemented using the personality() syscall, - which causes uname to return - i686 in child processes. - - - - Various improvements to the chroot - support. Building in a chroot works quite well - now. - - - - Nix no longer blocks if it tries to build a path and another - process is already building the same path. Instead it tries to - build another buildable path first. This improves - parallelism. - - - - Support for large (> 4 GiB) files in NAR archives. - - - - Various (performance) improvements to the remote build - mechanism. - - - - New primops: builtins.addErrorContext (to - add a string to stack traces — useful for debugging), - builtins.isBool, - builtins.isString, - builtins.isInt, - builtins.intersectAttrs. - - - - OpenSolaris support (Sander van der Burg). - - - - Stack traces are no longer displayed unless the - option is used. - - - - The scoping rules for inherit - (e) ... in recursive - attribute sets have changed. The expression - e can now refer to the attributes - defined in the containing set. - - - - -
- - - - -
Release 0.12 (November 20, -2008) - - - - - Nix no longer uses Berkeley DB to store Nix store metadata. - The principal advantages of the new storage scheme are: it works - properly over decent implementations of NFS (allowing Nix stores - to be shared between multiple machines); no recovery is needed - when a Nix process crashes; no write access is needed for - read-only operations; no more running out of Berkeley DB locks on - certain operations. - - You still need to compile Nix with Berkeley DB support if - you want Nix to automatically convert your old Nix store to the - new schema. If you don’t need this, you can build Nix with the - configure option - . - - After the automatic conversion to the new schema, you can - delete the old Berkeley DB files: - - -$ cd /nix/var/nix/db -$ rm __db* log.* derivers references referrers reserved validpaths DB_CONFIG - - The new metadata is stored in the directories - /nix/var/nix/db/info and - /nix/var/nix/db/referrer. Though the - metadata is stored in human-readable plain-text files, they are - not intended to be human-editable, as Nix is rather strict about - the format. - - The new storage schema may or may not require less disk - space than the Berkeley DB environment, mostly depending on the - cluster size of your file system. With 1 KiB clusters (which - seems to be the ext3 default nowadays) it - usually takes up much less space. - - - There is a new substituter that copies paths - directly from other (remote) Nix stores mounted somewhere in the - filesystem. For instance, you can speed up an installation by - mounting some remote Nix store that already has the packages in - question via NFS or sshfs. The environment - variable NIX_OTHER_STORES specifies the locations of - the remote Nix directories, - e.g. /mnt/remote-fs/nix. - - New nix-store operations - and to dump - and reload the Nix database. - - The garbage collector has a number of new options to - allow only some of the garbage to be deleted. The option - tells the - collector to stop after at least N bytes - have been deleted. The option tells it to stop after the - link count on /nix/store has dropped below - N. This is useful for very large Nix - stores on filesystems with a 32000 subdirectories limit (like - ext3). The option - causes store paths to be deleted in order of ascending last access - time. This allows non-recently used stuff to be deleted. The - option - specifies an upper limit to the last accessed time of paths that may - be deleted. For instance, - - - $ nix-store --gc -v --max-atime $(date +%s -d "2 months ago") - - deletes everything that hasn’t been accessed in two months. - - nix-env now uses optimistic - profile locking when performing an operation like installing or - upgrading, instead of setting an exclusive lock on the profile. - This allows multiple nix-env -i / -u / -e - operations on the same profile in parallel. If a - nix-env operation sees at the end that the profile - was changed in the meantime by another process, it will just - restart. This is generally cheap because the build results are - still in the Nix store. - - The option is now - supported by nix-store -r and - nix-build. - - The information previously shown by - (i.e., which derivations will be built - and which paths will be substituted) is now always shown by - nix-env, nix-store -r and - nix-build. The total download size of - substitutable paths is now also shown. For instance, a build will - show something like - - -the following derivations will be built: - /nix/store/129sbxnk5n466zg6r1qmq1xjv9zymyy7-activate-configuration.sh.drv - /nix/store/7mzy971rdm8l566ch8hgxaf89x7lr7ik-upstart-jobs.drv - ... -the following paths will be downloaded/copied (30.02 MiB): - /nix/store/4m8pvgy2dcjgppf5b4cj5l6wyshjhalj-samba-3.2.4 - /nix/store/7h1kwcj29ip8vk26rhmx6bfjraxp0g4l-libunwind-0.98.6 - ... - - - - Language features: - - - - @-patterns as in Haskell. For instance, in a - function definition - - f = args @ {x, y, z}: ...; - - args refers to the argument as a whole, which - is further pattern-matched against the attribute set pattern - {x, y, z}. - - “...” (ellipsis) patterns. - An attribute set pattern can now say ... at - the end of the attribute name list to specify that the function - takes at least the listed attributes, while - ignoring additional attributes. For instance, - - {stdenv, fetchurl, fuse, ...}: ... - - defines a function that accepts any attribute set that includes - at least the three listed attributes. - - New primops: - builtins.parseDrvName (split a package name - string like "nix-0.12pre12876" into its name - and version components, e.g. "nix" and - "0.12pre12876"), - builtins.compareVersions (compare two version - strings using the same algorithm that nix-env - uses), builtins.length (efficiently compute - the length of a list), builtins.mul (integer - multiplication), builtins.div (integer - division). - - - - - - - - nix-prefetch-url now supports - mirror:// URLs, provided that the environment - variable NIXPKGS_ALL points at a Nixpkgs - tree. - - Removed the commands - nix-pack-closure and - nix-unpack-closure. You can do almost the same - thing but much more efficiently by doing nix-store --export - $(nix-store -qR paths) > closure and - nix-store --import < - closure. - - Lots of bug fixes, including a big performance bug in - the handling of with-expressions. - - - -
- - - - -
Release 0.11 (December 31, -2007) - -Nix 0.11 has many improvements over the previous stable release. -The most important improvement is secure multi-user support. It also -features many usability enhancements and language extensions, many of -them prompted by NixOS, the purely functional Linux distribution based -on Nix. Here is an (incomplete) list: - - - - - - Secure multi-user support. A single Nix store can - now be shared between multiple (possible untrusted) users. This is - an important feature for NixOS, where it allows non-root users to - install software. The old setuid method for sharing a store between - multiple users has been removed. Details for setting up a - multi-user store can be found in the manual. - - - The new command nix-copy-closure - gives you an easy and efficient way to exchange software between - machines. It copies the missing parts of the closure of a set of - store path to or from a remote machine via - ssh. - - - A new kind of string literal: strings between double - single-quotes ('') have indentation - “intelligently” removed. This allows large strings (such as shell - scripts or configuration file fragments in NixOS) to cleanly follow - the indentation of the surrounding expression. It also requires - much less escaping, since '' is less common in - most languages than ". - - - nix-env - modifies the current generation of a profile so that it contains - exactly the specified derivation, and nothing else. For example, - nix-env -p /nix/var/nix/profiles/browser --set - firefox lets the profile named - browser contain just Firefox. - - - nix-env now maintains - meta-information about installed packages in profiles. The - meta-information is the contents of the meta - attribute of derivations, such as description or - homepage. The command nix-env -q --xml - --meta shows all meta-information. - - - nix-env now uses the - meta.priority attribute of derivations to resolve - filename collisions between packages. Lower priority values denote - a higher priority. For instance, the GCC wrapper package and the - Binutils package in Nixpkgs both have a file - bin/ld, so previously if you tried to install - both you would get a collision. Now, on the other hand, the GCC - wrapper declares a higher priority than Binutils, so the former’s - bin/ld is symlinked in the user - environment. - - - nix-env -i / -u: instead of - breaking package ties by version, break them by priority and version - number. That is, if there are multiple packages with the same name, - then pick the package with the highest priority, and only use the - version if there are multiple packages with the same - priority. - - This makes it possible to mark specific versions/variant in - Nixpkgs more or less desirable than others. A typical example would - be a beta version of some package (e.g., - gcc-4.2.0rc1) which should not be installed even - though it is the highest version, except when it is explicitly - selected (e.g., nix-env -i - gcc-4.2.0rc1). - - - nix-env --set-flag allows meta - attributes of installed packages to be modified. There are several - attributes that can be usefully modified, because they affect the - behaviour of nix-env or the user environment - build script: - - - - meta.priority can be changed - to resolve filename clashes (see above). - - meta.keep can be set to - true to prevent the package from being - upgraded or replaced. Useful if you want to hang on to an older - version of a package. - - meta.active can be set to - false to “disable” the package. That is, no - symlinks will be generated to the files of the package, but it - remains part of the profile (so it won’t be garbage-collected). - Set it back to true to re-enable the - package. - - - - - - - nix-env -q now has a flag - () that causes - nix-env to show only those derivations whose - output is already in the Nix store or that can be substituted (i.e., - downloaded from somewhere). In other words, it shows the packages - that can be installed “quickly”, i.e., don’t need to be built from - source. The flag is also available in - nix-env -i and nix-env -u to - filter out derivations for which no pre-built binary is - available. - - - The new option (in - nix-env, nix-instantiate and - nix-build) is like , except - that the value is a string. For example, --argstr system - i686-linux is equivalent to --arg system - \"i686-linux\" (note that - prevents annoying quoting around shell arguments). - - - nix-store has a new operation - () - paths that shows the build log of the given - paths. - - - - - - Nix now uses Berkeley DB 4.5. The database is - upgraded automatically, but you should be careful not to use old - versions of Nix that still use Berkeley DB 4.4. - - - - - - The option - (corresponding to the configuration setting - build-max-silent-time) allows you to set a - timeout on builds — if a build produces no output on - stdout or stderr for the given - number of seconds, it is terminated. This is useful for recovering - automatically from builds that are stuck in an infinite - loop. - - - nix-channel: each subscribed - channel is its own attribute in the top-level expression generated - for the channel. This allows disambiguation (e.g. nix-env - -i -A nixpkgs_unstable.firefox). - - - The substitutes table has been removed from the - database. This makes operations such as nix-pull - and nix-channel --update much, much - faster. - - - nix-pull now supports - bzip2-compressed manifests. This speeds up - channels. - - - nix-prefetch-url now has a - limited form of caching. This is used by - nix-channel to prevent unnecessary downloads when - the channel hasn’t changed. - - - nix-prefetch-url now by default - computes the SHA-256 hash of the file instead of the MD5 hash. In - calls to fetchurl you should pass the - sha256 attribute instead of - md5. You can pass either a hexadecimal or a - base-32 encoding of the hash. - - - Nix can now perform builds in an automatically - generated “chroot”. This prevents a builder from accessing stuff - outside of the Nix store, and thus helps ensure purity. This is an - experimental feature. - - - The new command nix-store - --optimise reduces Nix store disk space usage by finding - identical files in the store and hard-linking them to each other. - It typically reduces the size of the store by something like - 25-35%. - - - ~/.nix-defexpr can now be a - directory, in which case the Nix expressions in that directory are - combined into an attribute set, with the file names used as the - names of the attributes. The command nix-env - --import (which set the - ~/.nix-defexpr symlink) is - removed. - - - Derivations can specify the new special attribute - allowedReferences to enforce that the references - in the output of a derivation are a subset of a declared set of - paths. For example, if allowedReferences is an - empty list, then the output must not have any references. This is - used in NixOS to check that generated files such as initial ramdisks - for booting Linux don’t have any dependencies. - - - The new attribute - exportReferencesGraph allows builders access to - the references graph of their inputs. This is used in NixOS for - tasks such as generating ISO-9660 images that contain a Nix store - populated with the closure of certain paths. - - - Fixed-output derivations (like - fetchurl) can define the attribute - impureEnvVars to allow external environment - variables to be passed to builders. This is used in Nixpkgs to - support proxy configuration, among other things. - - - Several new built-in functions: - builtins.attrNames, - builtins.filterSource, - builtins.isAttrs, - builtins.isFunction, - builtins.listToAttrs, - builtins.stringLength, - builtins.sub, - builtins.substring, - throw, - builtins.trace, - builtins.readFile. - - - - -
- - - - - -
Release 0.10.1 (October 11, 2006) - -This release fixes two somewhat obscure bugs that occur when -evaluating Nix expressions that are stored inside the Nix store -(NIX-67). These do not affect most users. - -
- - - - - -
Release 0.10 (October 6, 2006) - -This version of Nix uses Berkeley DB 4.4 instead of 4.3. -The database is upgraded automatically, but you should be careful not -to use old versions of Nix that still use Berkeley DB 4.3. In -particular, if you use a Nix installed through Nix, you should run - - -$ nix-store --clear-substitutes - -first. - -Also, the database schema has changed slighted to fix a -performance issue (see below). When you run any Nix 0.10 command for -the first time, the database will be upgraded automatically. This is -irreversible. - - - - - - - - nix-env usability improvements: - - - - An option - (or ) has been added to nix-env - --query to allow you to compare installed versions of - packages to available versions, or vice versa. An easy way to - see if you are up to date with what’s in your subscribed - channels is nix-env -qc \*. - - nix-env --query now takes as - arguments a list of package names about which to show - information, just like , etc.: for - example, nix-env -q gcc. Note that to show - all derivations, you need to specify - \*. - - nix-env -i - pkgname will now install - the highest available version of - pkgname, rather than installing all - available versions (which would probably give collisions) - (NIX-31). - - nix-env (-i|-u) --dry-run now - shows exactly which missing paths will be built or - substituted. - - nix-env -qa --description - shows human-readable descriptions of packages, provided that - they have a meta.description attribute (which - most packages in Nixpkgs don’t have yet). - - - - - - - New language features: - - - - Reference scanning (which happens after each - build) is much faster and takes a constant amount of - memory. - - String interpolation. Expressions like - - -"--with-freetype2-library=" + freetype + "/lib" - - can now be written as - - -"--with-freetype2-library=${freetype}/lib" - - You can write arbitrary expressions within - ${...}, not just - identifiers. - - Multi-line string literals. - - String concatenations can now involve - derivations, as in the example "--with-freetype2-library=" - + freetype + "/lib". This was not previously possible - because we need to register that a derivation that uses such a - string is dependent on freetype. The - evaluator now properly propagates this information. - Consequently, the subpath operator (~) has - been deprecated. - - Default values of function arguments can now - refer to other function arguments; that is, all arguments are in - scope in the default values - (NIX-45). - - - - Lots of new built-in primitives, such as - functions for list manipulation and integer arithmetic. See the - manual for a complete list. All primops are now available in - the set builtins, allowing one to test for - the availability of primop in a backwards-compatible - way. - - Real let-expressions: let x = ...; - ... z = ...; in .... - - - - - - - New commands nix-pack-closure and - nix-unpack-closure than can be used to easily - transfer a store path with all its dependencies to another machine. - Very convenient whenever you have some package on your machine and - you want to copy it somewhere else. - - - XML support: - - - - nix-env -q --xml prints the - installed or available packages in an XML representation for - easy processing by other tools. - - nix-instantiate --eval-only - --xml prints an XML representation of the resulting - term. (The new flag forces ‘deep’ - evaluation of the result, i.e., list elements and attributes are - evaluated recursively.) - - In Nix expressions, the primop - builtins.toXML converts a term to an XML - representation. This is primarily useful for passing structured - information to builders. - - - - - - - You can now unambiguously specify which derivation to - build or install in nix-env, - nix-instantiate and nix-build - using the / flags, which - takes an attribute name as argument. (Unlike symbolic package names - such as subversion-1.4.0, attribute names in an - attribute set are unique.) For instance, a quick way to perform a - test build of a package in Nixpkgs is nix-build - pkgs/top-level/all-packages.nix -A - foo. nix-env -q - --attr shows the attribute names corresponding to each - derivation. - - - If the top-level Nix expression used by - nix-env, nix-instantiate or - nix-build evaluates to a function whose arguments - all have default values, the function will be called automatically. - Also, the new command-line switch can be used to specify - function arguments on the command line. - - - nix-install-package --url - URL allows a package to be - installed directly from the given URL. - - - Nix now works behind an HTTP proxy server; just set - the standard environment variables http_proxy, - https_proxy, ftp_proxy or - all_proxy appropriately. Functions such as - fetchurl in Nixpkgs also respect these - variables. - - - nix-build -o - symlink allows the symlink to - the build result to be named something other than - result. - - - - - - Platform support: - - - - Support for 64-bit platforms, provided a suitably - patched ATerm library is used. Also, files larger than 2 - GiB are now supported. - - Added support for Cygwin (Windows, - i686-cygwin), Mac OS X on Intel - (i686-darwin) and Linux on PowerPC - (powerpc-linux). - - Users of SMP and multicore machines will - appreciate that the number of builds to be performed in parallel - can now be specified in the configuration file in the - build-max-jobs setting. - - - - - - - Garbage collector improvements: - - - - Open files (such as running programs) are now - used as roots of the garbage collector. This prevents programs - that have been uninstalled from being garbage collected while - they are still running. The script that detects these - additional runtime roots - (find-runtime-roots.pl) is inherently - system-specific, but it should work on Linux and on all - platforms that have the lsof - utility. - - nix-store --gc - (a.k.a. nix-collect-garbage) prints out the - number of bytes freed on standard output. nix-store - --gc --print-dead shows how many bytes would be freed - by an actual garbage collection. - - nix-collect-garbage -d - removes all old generations of all profiles - before calling the actual garbage collector (nix-store - --gc). This is an easy way to get rid of all old - packages in the Nix store. - - nix-store now has an - operation to delete specific paths - from the Nix store. It won’t delete reachable (non-garbage) - paths unless is - specified. - - - - - - - Berkeley DB 4.4’s process registry feature is used - to recover from crashed Nix processes. - - - - A performance issue has been fixed with the - referer table, which stores the inverse of the - references table (i.e., it tells you what store - paths refer to a given path). Maintaining this table could take a - quadratic amount of time, as well as a quadratic amount of Berkeley - DB log file space (in particular when running the garbage collector) - (NIX-23). - - Nix now catches the TERM and - HUP signals in addition to the - INT signal. So you can now do a killall - nix-store without triggering a database - recovery. - - bsdiff updated to version - 4.3. - - Substantial performance improvements in expression - evaluation and nix-env -qa, all thanks to Valgrind. Memory use has - been reduced by a factor 8 or so. Big speedup by memoisation of - path hashing. - - Lots of bug fixes, notably: - - - - Make sure that the garbage collector can run - successfully when the disk is full - (NIX-18). - - nix-env now locks the profile - to prevent races between concurrent nix-env - operations on the same profile - (NIX-7). - - Removed misleading messages from - nix-env -i (e.g., installing - `foo' followed by uninstalling - `foo') (NIX-17). - - - - - - Nix source distributions are a lot smaller now since - we no longer include a full copy of the Berkeley DB source - distribution (but only the bits we need). - - Header files are now installed so that external - programs can use the Nix libraries. - - - -

Release 0.9.2 (September 21, 2005) - -This bug fix release fixes two problems on Mac OS X: - - - - If Nix was linked against statically linked versions - of the ATerm or Berkeley DB library, there would be dynamic link - errors at runtime. - - nix-pull and - nix-push intermittently failed due to race - conditions involving pipes and child processes with error messages - such as open2: open(GLOB(0x180b2e4), >&=9) failed: Bad - file descriptor at /nix/bin/nix-pull line 77 (issue - NIX-14). - - - - - -
- - - - - -
Release 0.9.1 (September 20, 2005) - -This bug fix release addresses a problem with the ATerm library -when the flag in -configure was not used. - -
- - - - - -
Release 0.9 (September 16, 2005) - -NOTE: this version of Nix uses Berkeley DB 4.3 instead of 4.2. -The database is upgraded automatically, but you should be careful not -to use old versions of Nix that still use Berkeley DB 4.2. In -particular, if you use a Nix installed through Nix, you should run - - -$ nix-store --clear-substitutes - -first. - - - - - Unpacking of patch sequences is much faster now - since we no longer do redundant unpacking and repacking of - intermediate paths. - - Nix now uses Berkeley DB 4.3. - - The derivation primitive is - lazier. Attributes of dependent derivations can mutually refer to - each other (as long as there are no data dependencies on the - outPath and drvPath attributes - computed by derivation). - - For example, the expression derivation - attrs now evaluates to (essentially) - - -attrs // { - type = "derivation"; - outPath = derivation! attrs; - drvPath = derivation! attrs; -} - - where derivation! is a primop that does the - actual derivation instantiation (i.e., it does what - derivation used to do). The advantage is that - it allows commands such as nix-env -qa and - nix-env -i to be much faster since they no longer - need to instantiate all derivations, just the - name attribute. - - Also, it allows derivations to cyclically reference each - other, for example, - - -webServer = derivation { - ... - hostName = "svn.cs.uu.nl"; - services = [svnService]; -}; - -svnService = derivation { - ... - hostName = webServer.hostName; -}; - - Previously, this would yield a black hole (infinite recursion). - - - - nix-build now defaults to using - ./default.nix if no Nix expression is - specified. - - nix-instantiate, when applied to - a Nix expression that evaluates to a function, will call the - function automatically if all its arguments have - defaults. - - Nix now uses libtool to build dynamic libraries. - This reduces the size of executables. - - A new list concatenation operator - ++. For example, [1 2 3] ++ [4 5 - 6] evaluates to [1 2 3 4 5 - 6]. - - Some currently undocumented primops to support - low-level build management using Nix (i.e., using Nix as a Make - replacement). See the commit messages for r3578 - and r3580. - - Various bug fixes and performance - improvements. - - - -
- - - - - -
Release 0.8.1 (April 13, 2005) - -This is a bug fix release. - - - - Patch downloading was broken. - - The garbage collector would not delete paths that - had references from invalid (but substitutable) - paths. - - - -
- - - - - -
Release 0.8 (April 11, 2005) - -NOTE: the hashing scheme in Nix 0.8 changed (as detailed below). -As a result, nix-pull manifests and channels built -for Nix 0.7 and below will now work anymore. However, the Nix -expression language has not changed, so you can still build from -source. Also, existing user environments continue to work. Nix 0.8 -will automatically upgrade the database schema of previous -installations when it is first run. - -If you get the error message - - -you have an old-style manifest `/nix/var/nix/manifests/[...]'; please -delete it - -you should delete previously downloaded manifests: - - -$ rm /nix/var/nix/manifests/* - -If nix-channel gives the error message - - -manifest `http://catamaran.labs.cs.uu.nl/dist/nix/channels/[channel]/MANIFEST' -is too old (i.e., for Nix <= 0.7) - -then you should unsubscribe from the offending channel -(nix-channel --remove -URL; leave out -/MANIFEST), and subscribe to the same URL, with -channels replaced by channels-v3 -(e.g., ). - -Nix 0.8 has the following improvements: - - - - The cryptographic hashes used in store paths are now - 160 bits long, but encoded in base-32 so that they are still only 32 - characters long (e.g., - /nix/store/csw87wag8bqlqk7ipllbwypb14xainap-atk-1.9.0). - (This is actually a 160 bit truncation of a SHA-256 - hash.) - - Big cleanups and simplifications of the basic store - semantics. The notion of “closure store expressions” is gone (and - so is the notion of “successors”); the file system references of a - store path are now just stored in the database. - - For instance, given any store path, you can query its closure: - - -$ nix-store -qR $(which firefox) -... lots of paths ... - - Also, Nix now remembers for each store path the derivation that - built it (the “deriver”): - - -$ nix-store -qR $(which firefox) -/nix/store/4b0jx7vq80l9aqcnkszxhymsf1ffa5jd-firefox-1.0.1.drv - - So to see the build-time dependencies, you can do - - -$ nix-store -qR $(nix-store -qd $(which firefox)) - - or, in a nicer format: - - -$ nix-store -q --tree $(nix-store -qd $(which firefox)) - - - - File system references are also stored in reverse. For - instance, you can query all paths that directly or indirectly use a - certain Glibc: - - -$ nix-store -q --referrers-closure \ - /nix/store/8lz9yc6zgmc0vlqmn2ipcpkjlmbi51vv-glibc-2.3.4 - - - - - - The concept of fixed-output derivations has been - formalised. Previously, functions such as - fetchurl in Nixpkgs used a hack (namely, - explicitly specifying a store path hash) to prevent changes to, say, - the URL of the file from propagating upwards through the dependency - graph, causing rebuilds of everything. This can now be done cleanly - by specifying the outputHash and - outputHashAlgo attributes. Nix itself checks - that the content of the output has the specified hash. (This is - important for maintaining certain invariants necessary for future - work on secure shared stores.) - - One-click installation :-) It is now possible to - install any top-level component in Nixpkgs directly, through the web - — see, e.g., . - All you have to do is associate - /nix/bin/nix-install-package with the MIME type - application/nix-package (or the extension - .nixpkg), and clicking on a package link will - cause it to be installed, with all appropriate dependencies. If you - just want to install some specific application, this is easier than - subscribing to a channel. - - nix-store -r - PATHS now builds all the - derivations PATHS in parallel. Previously it did them sequentially - (though exploiting possible parallelism between subderivations). - This is nice for build farms. - - nix-channel has new operations - and - . - - New ways of installing components into user - environments: - - - - Copy from another user environment: - - -$ nix-env -i --from-profile .../other-profile firefox - - - - Install a store derivation directly (bypassing the - Nix expression language entirely): - - -$ nix-env -i /nix/store/z58v41v21xd3...-aterm-2.3.1.drv - - (This is used to implement nix-install-package, - which is therefore immune to evolution in the Nix expression - language.) - - Install an already built store path directly: - - -$ nix-env -i /nix/store/hsyj5pbn0d9i...-aterm-2.3.1 - - - - Install the result of a Nix expression specified - as a command-line argument: - - -$ nix-env -f .../i686-linux.nix -i -E 'x: x.firefoxWrapper' - - The difference with the normal installation mode is that - does not use the name - attributes of derivations. Therefore, this can be used to - disambiguate multiple derivations with the same - name. - - - - A hash of the contents of a store path is now stored - in the database after a successful build. This allows you to check - whether store paths have been tampered with: nix-store - --verify --check-contents. - - - - Implemented a concurrent garbage collector. It is now - always safe to run the garbage collector, even if other Nix - operations are happening simultaneously. - - However, there can still be GC races if you use - nix-instantiate and nix-store - --realise directly to build things. To prevent races, - use the flag of those commands. - - - - The garbage collector now finally deletes paths in - the right order (i.e., topologically sorted under the “references” - relation), thus making it safe to interrupt the collector without - risking a store that violates the closure - invariant. - - Likewise, the substitute mechanism now downloads - files in the right order, thus preserving the closure invariant at - all times. - - The result of nix-build is now - registered as a root of the garbage collector. If the - ./result link is deleted, the GC root - disappears automatically. - - - - The behaviour of the garbage collector can be changed - globally by setting options in - /nix/etc/nix/nix.conf. - - - - gc-keep-derivations specifies - whether deriver links should be followed when searching for live - paths. - - gc-keep-outputs specifies - whether outputs of derivations should be followed when searching - for live paths. - - env-keep-derivations - specifies whether user environments should store the paths of - derivations when they are added (thus keeping the derivations - alive). - - - - - - New nix-env query flags - and - . - - fetchurl allows SHA-1 and SHA-256 - in addition to MD5. Just specify the attribute - sha1 or sha256 instead of - md5. - - Manual updates. - - - - - -
- - - - - -
Release 0.7 (January 12, 2005) - - - - Binary patching. When upgrading components using - pre-built binaries (through nix-pull / nix-channel), Nix can - automatically download and apply binary patches to already installed - components instead of full downloads. Patching is “smart”: if there - is a sequence of patches to an installed - component, Nix will use it. Patches are currently generated - automatically between Nixpkgs (pre-)releases. - - Simplifications to the substitute - mechanism. - - Nix-pull now stores downloaded manifests in - /nix/var/nix/manifests. - - Metadata on files in the Nix store is canonicalised - after builds: the last-modified timestamp is set to 0 (00:00:00 - 1/1/1970), the mode is set to 0444 or 0555 (readable and possibly - executable by all; setuid/setgid bits are dropped), and the group is - set to the default. This ensures that the result of a build and an - installation through a substitute is the same; and that timestamp - dependencies are revealed. - - - -
- - - - - -
Release 0.6 (November 14, 2004) - - - - - Rewrite of the normalisation engine. - - - - Multiple builds can now be performed in parallel - (option ). - - Distributed builds. Nix can now call a shell - script to forward builds to Nix installations on remote - machines, which may or may not be of the same platform - type. - - Option allows - recovery from broken substitutes. - - Option causes - building of other (unaffected) derivations to continue if one - failed. - - - - - - - - Improvements to the garbage collector (i.e., it - should actually work now). - - Setuid Nix installations allow a Nix store to be - shared among multiple users. - - Substitute registration is much faster - now. - - A utility nix-build to build a - Nix expression and create a symlink to the result int the current - directory; useful for testing Nix derivations. - - Manual updates. - - - - nix-env changes: - - - - Derivations for other platforms are filtered out - (which can be overridden using - ). - - by default now - uninstall previous derivations with the same - name. - - allows upgrading to a - specific version. - - New operation - to remove profile - generations (necessary for effective garbage - collection). - - Nicer output (sorted, - columnised). - - - - - - - - More sensible verbosity levels all around (builder - output is now shown always, unless is - given). - - - - Nix expression language changes: - - - - New language construct: with - E1; - E2 brings all attributes - defined in the attribute set E1 in - scope in E2. - - Added a map - function. - - Various new operators (e.g., string - concatenation). - - - - - - - - Expression evaluation is much - faster. - - An Emacs mode for editing Nix expressions (with - syntax highlighting and indentation) has been - added. - - Many bug fixes. - - - -

It's actually already in the Nix Packages collection in -pkgs/applications/misc/hello/ex-1/default.nix. -It is customary to place each package in a separate directory and call -the single Nix expression in that directory -default.nix.

They are needed to build Hello, but - we don't know how to build them here; that's why they are function - arguments. stdenv is a package that is used - by almost all Nix Packages packages; it provides a - standard environment consisting of the things you - would expect in a basic Unix environment: a C/C++ compiler (GCC, - to be precise), the Bash shell, fundamental Unix tools such as - cp, grep, - tar, etc. fetchurl is a - function that downloads files. perl is the - Perl interpreter. - - Nix functions generally have the form { x, y, ..., - z }: e where x, y, - etc. are the names of the expected arguments, and where - e is the body of the function.

Building something from - other stuff is called a derivation in Nix (as - opposed to sources, which are built by humans instead of - computers). We perform a derivation by calling - stdenv.mkDerivation. - mkDerivation is a function provided by - stdenv that builds a package from a set of - attributes.

This attribute can sometimes be omitted, in which case - mkDerivation will fill in a default builder - (which does a configure; make; make install, in - essence). Hello is sufficiently simple that the default builder - would suffice, but in this case, we will show an actual builder - for educational purposes.

Here, the attribute src is bound to the - result of a call to the fetchurl function. - Given a URL and an MD5 hash of the expected contents of the file - at that URL, this function builds a derivation that downloads the - file and checks its hash. So the sources are a dependency that - like all other dependencies is built before Hello itself is - built. - - Instead of src any other name could have - been used, and in fact there can be any number of sources (bound - to different attributes). However, src is - customary, and it's also expected by the default builder (which we - don't use in this example). - - - - - - Since the derivation requires Perl, we have to pass the - value of the perl function argument to the - builder. All attributes in the set are actually passed as - environment variables to the builder, so declaring an attribute - - -perl = perl; - - will do the trick: it binds an attribute perl - to the function argument which also happens to be called - perl. However, it looks a bit silly, so there - is a shorter syntax. The inherit keyword - causes the specified attributes to be bound to whatever variables - with the same name happen to be in scope. - - - - - - - -

The builder - -Build script for GNU Hello -(<filename>builder.sh</filename>) - -source $stdenv/setup - -PATH=$perl/bin:$PATH - -tar xvfz $src -cd hello-* -./configure --prefix=$out -make -make install - - - shows the builder referenced -from Hello's Nix expression (stored in -pkgs/applications/misc/hello/ex-1/builder.sh). -The builder can actually be made a lot shorter by using the -generic builder functions provided by -stdenv, but here we write out the build steps to -elucidate what a builder does. It performs the following -steps: - - - - - - When Nix runs a builder, it initially completely clears the - environment (except for the attributes declared in the - derivation). For instance, the PATH variable is - emptyActually, it's initialised to - /path-not-set to prevent Bash from setting it - to a default value.. This is done to prevent - undeclared inputs from being used in the build process. If for - example the PATH contained - /usr/bin, then you might accidentally use - /usr/bin/gcc. - - So the first step is to set up the environment. This is - done by calling the setup script of the - standard environment. The environment variable - stdenv points to the location of the standard - environment being used. (It wasn't specified explicitly as an - attribute in , but - mkDerivation adds it automatically.) - - - - - - Since Hello needs Perl, we have to make sure that Perl is in - the PATH. The perl environment - variable points to the location of the Perl package (since it - was passed in as an attribute to the derivation), so - $perl/bin is the - directory containing the Perl interpreter. - - - - - - Now we have to unpack the sources. The - src attribute was bound to the result of - fetching the Hello source tarball from the network, so the - src environment variable points to the location in - the Nix store to which the tarball was downloaded. After - unpacking, we cd to the resulting source - directory. - - The whole build is performed in a temporary directory - created in /tmp, by the way. This directory is - removed after the builder finishes, so there is no need to clean - up the sources afterwards. Also, the temporary directory is - always newly created, so you don't have to worry about files from - previous builds interfering with the current build. - - - - - - GNU Hello is a typical Autoconf-based package, so we first - have to run its configure script. In Nix - every package is stored in a separate location in the Nix store, - for instance - /nix/store/9a54ba97fb71b65fda531012d0443ce2-hello-2.1.1. - Nix computes this path by cryptographically hashing all attributes - of the derivation. The path is passed to the builder through the - out environment variable. So here we give - configure the parameter - --prefix=$out to cause Hello to be installed in - the expected location. - - - - - - Finally we build Hello (make) and install - it into the location specified by out - (make install). - - - - - -If you are wondering about the absence of error checking on the -result of various commands called in the builder: this is because the -shell script is evaluated with Bash's option, -which causes the script to be aborted if any command fails without an -error check. - -

Composition - -Composing GNU Hello -(<filename>all-packages.nix</filename>) - -... - -rec { - - hello = import ../applications/misc/hello/ex-1 { - inherit fetchurl stdenv perl; - }; - - perl = import ../development/interpreters/perl { - inherit fetchurl stdenv; - }; - - fetchurl = import ../build-support/fetchurl { - inherit stdenv; ... - }; - - stdenv = ...; - -} - - - -The Nix expression in is a -function; it is missing some arguments that have to be filled in -somewhere. In the Nix Packages collection this is done in the file -pkgs/top-level/all-packages.nix, where all -Nix expressions for packages are imported and called with the -appropriate arguments. shows -some fragments of -all-packages.nix. - - - - - - This file defines a set of attributes, all of which are - concrete derivations (i.e., not functions). In fact, we define a - mutually recursive set of attributes. That - is, the attributes can refer to each other. This is precisely - what we want since we want to plug the - various packages into each other. - - - - - - Here we import the Nix expression for - GNU Hello. The import operation just loads and returns the - specified Nix expression. In fact, we could just have put the - contents of in - all-packages.nix at this point. That - would be completely equivalent, but it would make the file rather - bulky. - - Note that we refer to - ../applications/misc/hello/ex-1, not - ../applications/misc/hello/ex-1/default.nix. - When you try to import a directory, Nix automatically appends - /default.nix to the file name. - - - - - - This is where the actual composition takes place. Here we - call the function imported from - ../applications/misc/hello/ex-1 with a set - containing the things that the function expects, namely - fetchurl, stdenv, and - perl. We use inherit again to use the - attributes defined in the surrounding scope (we could also have - written fetchurl = fetchurl;, etc.). - - The result of this function call is an actual derivation - that can be built by Nix (since when we fill in the arguments of - the function, what we get is its body, which is the call to - stdenv.mkDerivation in ). - - Nixpkgs has a convenience function - callPackage that imports and calls a - function, filling in any missing arguments by passing the - corresponding attribute from the Nixpkgs set, like this: - - -hello = callPackage ../applications/misc/hello/ex-1 { }; - - - If necessary, you can set or override arguments: - - -hello = callPackage ../applications/misc/hello/ex-1 { stdenv = myStdenv; }; - - - - - - - - - Likewise, we have to instantiate Perl, - fetchurl, and the standard environment. - - - - - -

Testing - -You can now try to build Hello. Of course, you could do -nix-env -f pkgs/top-level/all-packages.nix -i hello, -but you may not want to install a possibly broken package just yet. -The best way to test the package is by using the command nix-build, which builds a Nix -expression and creates a symlink named result in -the current directory: - - -$ nix-build pkgs/top-level/all-packages.nix -A hello -building path `/nix/store/632d2b22514d...-hello-2.1.1' -hello-2.1.1/ -hello-2.1.1/intl/ -hello-2.1.1/intl/ChangeLog -... - -$ ls -l result -lrwxrwxrwx ... 2006-09-29 10:43 result -> /nix/store/632d2b22514d...-hello-2.1.1 - -$ ./result/bin/hello -Hello, world! - -The option selects -the hello attribute from -all-packages.nix. This is faster than using the -symbolic package name specified by the name -attribute (which also happens to be hello) and is -unambiguous (there can be multiple packages with the symbolic name -hello, but there can be only one attribute in a set -named hello). - -nix-build registers the -./result symlink as a garbage collection root, so -unless and until you delete the ./result symlink, -the output of the build will be safely kept on your system. You can -use nix-build’s switch to give the symlink another -name. - -Nix has a transactional semantics. Once a build finishes -successfully, Nix makes a note of this in its database: it registers -that the path denoted by out is now -valid. If you try to build the derivation again, Nix -will see that the path is already valid and finish immediately. If a -build fails, either because it returns a non-zero exit code, because -Nix or the builder are killed, or because the machine crashes, then -the output paths will not be registered as valid. If you try to build -the derivation again, Nix will remove the output paths if they exist -(e.g., because the builder died half-way through make -install) and try again. Note that there is no -negative caching: Nix doesn't remember that a build -failed, and so a failed build can always be repeated. This is because -Nix cannot distinguish between permanent failures (e.g., a compiler -error due to a syntax error in the source) and transient failures -(e.g., a disk full condition). - -Nix also performs locking. If you run multiple Nix builds -simultaneously, and they try to build the same derivation, the first -Nix instance that gets there will perform the build, while the others -block (or perform other derivations if available) until the build -finishes: - - -$ nix-build pkgs/top-level/all-packages.nix -A hello -waiting for lock on `/nix/store/0h5b7hp8d4hqfrw8igvx97x1xawrjnac-hello-2.1.1x' - -So it is always safe to run multiple instances of Nix in parallel -(which isn’t the case with, say, make). - -If you have a system with multiple CPUs, you may want to have -Nix build different derivations in parallel (insofar as possible). -Just pass the option , where -N is the maximum number of jobs to be run -in parallel, or set. Typically this should be the number of -CPUs. - -

The generic builder - -Recall from that the builder -looked something like this: - - -PATH=$perl/bin:$PATH -tar xvfz $src -cd hello-* -./configure --prefix=$out -make -make install - -The builders for almost all Unix packages look like this — set up some -environment variables, unpack the sources, configure, build, and -install. For this reason the standard environment provides some Bash -functions that automate the build process. A builder using the -generic build facilities in shown in . - -Build script using the generic -build functions - -buildInputs="$perl" - -source $stdenv/setup - -genericBuild - - - - - - - The buildInputs variable tells - setup to use the indicated packages as - inputs. This means that if a package provides a - bin subdirectory, it's added to - PATH; if it has a include - subdirectory, it's added to GCC's header search path; and so - on.How does it work? setup - tries to source the file - pkg/nix-support/setup-hook - of all dependencies. These “setup hooks” can then set up whatever - environment variables they want; for instance, the setup hook for - Perl sets the PERL5LIB environment variable to - contain the lib/site_perl directories of all - inputs. - - - - - - - The function genericBuild is defined in - the file $stdenv/setup. - - - - - - The final step calls the shell function - genericBuild, which performs the steps that - were done explicitly in . The - generic builder is smart enough to figure out whether to unpack - the sources using gzip, - bzip2, etc. It can be customised in many ways; - see . - - - - - -Discerning readers will note that the -buildInputs could just as well have been set in the Nix -expression, like this: - - - buildInputs = [ perl ]; - -The perl attribute can then be removed, and the -builder becomes even shorter: - - -source $stdenv/setup -genericBuild - -In fact, mkDerivation provides a default builder -that looks exactly like that, so it is actually possible to omit the -builder for Hello entirely. - -

The Nix expression language - -The Nix expression language is a pure, lazy, functional -language. Purity means that operations in the language don't have -side-effects (for instance, there is no variable assignment). -Laziness means that arguments to functions are evaluated only when -they are needed. Functional means that functions are -normal values that can be passed around and manipulated -in interesting ways. The language is not a full-featured, general -purpose language. Its main job is to describe packages, -compositions of packages, and the variability within -packages. - -This section presents the various features of the -language. - - -
Values - - -Simple values - -Nix has the following basic data types: - - - - - - Strings can be written in three - ways. - - The most common way is to enclose the string between double - quotes, e.g., "foo bar". Strings can span - multiple lines. The special characters " and - \ and the character sequence - ${ must be escaped by prefixing them with a - backslash (\). Newlines, carriage returns and - tabs can be written as \n, - \r and \t, - respectively. - - You can include the result of an expression into a string by - enclosing it in - ${...}, a feature - known as antiquotation. The enclosed - expression must evaluate to something that can be coerced into a - string (meaning that it must be a string, a path, or a - derivation). For instance, rather than writing - - -"--with-freetype2-library=" + freetype + "/lib" - - (where freetype is a derivation), you can - instead write the more natural - - -"--with-freetype2-library=${freetype}/lib" - - The latter is automatically translated to the former. A more - complicated example (from the Nix expression for Qt): - - -configureFlags = " - -system-zlib -system-libpng -system-libjpeg - ${if openglSupport then "-dlopen-opengl - -L${mesa}/lib -I${mesa}/include - -L${libXmu}/lib -I${libXmu}/include" else ""} - ${if threadSupport then "-thread" else "-no-thread"} -"; - - Note that Nix expressions and strings can be arbitrarily nested; - in this case the outer string contains various antiquotations that - themselves contain strings (e.g., "-thread"), - some of which in turn contain expressions (e.g., - ${mesa}). - - The second way to write string literals is as an - indented string, which is enclosed between - pairs of double single-quotes, like so: - - -'' - This is the first line. - This is the second line. - This is the third line. -'' - - This kind of string literal intelligently strips indentation from - the start of each line. To be precise, it strips from each line a - number of spaces equal to the minimal indentation of the string as - a whole (disregarding the indentation of empty lines). For - instance, the first and second line are indented two space, while - the third line is indented four spaces. Thus, two spaces are - stripped from each line, so the resulting string is - - -"This is the first line.\nThis is the second line.\n This is the third line.\n" - - - - Note that the whitespace and newline following the opening - '' is ignored if there is no non-whitespace - text on the initial line. - - Antiquotation - (${expr}) is - supported in indented strings. - - Since ${ and '' have - special meaning in indented strings, you need a way to quote them. - ${ can be escaped by prefixing it with - '' (that is, two single quotes), i.e., - ''${. '' can be escaped by - prefixing it with ', i.e., - '''. Finally, linefeed, carriage-return and - tab characters can be written as ''\n, - ''\r, ''\t. - - Indented strings are primarily useful in that they allow - multi-line string literals to follow the indentation of the - enclosing Nix expression, and that less escaping is typically - necessary for strings representing languages such as shell scripts - and configuration files because '' is much less - common than ". Example: - - -stdenv.mkDerivation { - ... - postInstall = - '' - mkdir $out/bin $out/etc - cp foo $out/bin - echo "Hello World" > $out/etc/foo.conf - ${if enableBar then "cp bar $out/bin" else ""} - ''; - ... -} - - - - - Finally, as a convenience, URIs as - defined in appendix B of RFC 2396 - can be written as is, without quotes. For - instance, the string - "http://example.org/foo.tar.bz2" - can also be written as - http://example.org/foo.tar.bz2. - - - - Integers, e.g., - 123. - - Paths, e.g., - /bin/sh or ./builder.sh. - A path must contain at least one slash to be recognised as such; for - instance, builder.sh is not a - pathIt's parsed as an expression that selects the - attribute sh from the variable - builder.. If the file name is - relative, i.e., if it does not begin with a slash, it is made - absolute at parse time relative to the directory of the Nix - expression that contained it. For instance, if a Nix expression in - /foo/bar/bla.nix refers to - ../xyzzy/fnord.nix, the absolute path is - /foo/xyzzy/fnord.nix. - - Booleans with values - true and - false. - - The null value, denoted as - null. - - - - - - - - -Lists - -Lists are formed by enclosing a whitespace-separated list of -values between square brackets. For example, - - -[ 123 ./foo.nix "abc" (f { x = y; }) ] - -defines a list of four elements, the last being the result of a call -to the function f. Note that function calls have -to be enclosed in parentheses. If they had been omitted, e.g., - - -[ 123 ./foo.nix "abc" f { x = y; } ] - -the result would be a list of five elements, the fourth one being a -function and the fifth being a set. - - - - -Sets - -Sets are really the core of the language, since ultimately the -Nix language is all about creating derivations, which are really just -sets of attributes to be passed to build scripts. - -Sets are just a list of name/value pairs (called -attributes) enclosed in curly brackets, where -each value is an arbitrary expression terminated by a semicolon. For -example: - - -{ x = 123; - text = "Hello"; - y = f { bla = 456; }; -} - -This defines a set with attributes named x, -text, y. The order of the -attributes is irrelevant. An attribute name may only occur -once. - -Attributes can be selected from a set using the -. operator. For instance, - - -{ a = "Foo"; b = "Bar"; }.a - -evaluates to "Foo". It is possible to provide a -default value in an attribute selection using the -or keyword. For example, - - -{ a = "Foo"; b = "Bar"; }.c or "Xyzzy" - -will evaluate to "Xyzzy" because there is no -c attribute in the set. - -You can use arbitrary double-quoted strings as attribute -names: - - -{ "foo ${bar}" = 123; "nix-1.0" = 456; }."foo ${bar}" - - -This will evaluate to 123 (Assuming -bar is antiquotable). In the case where an -attribute name is just a single antiquotation, the quotes can be -dropped: - - -{ foo = 123; }.${bar} or 456 - -This will evaluate to 123 if -bar evaluates to "foo" when -coerced to a string and 456 otherwise (again -assuming bar is antiquotable). - -In the special case where an attribute name inside of a set declaration -evaluates to null (which is normally an error, as -null is not antiquotable), that attribute is simply not -added to the set: - - -{ ${if foo then "bar" else null} = true; } - -This will evaluate to {} if foo -evaluates to false. - - - - - -
- - -
Language constructs - - -Recursive sets - -Recursive sets are just normal sets, but the attributes can -refer to each other. For example, - - -rec { - x = y; - y = 123; -}.x - - -evaluates to 123. Note that without -rec the binding x = y; would -refer to the variable y in the surrounding scope, -if one exists, and would be invalid if no such variable exists. That -is, in a normal (non-recursive) set, attributes are not added to the -lexical scope; in a recursive set, they are. - -Recursive sets of course introduce the danger of infinite -recursion. For example, - - -rec { - x = y; - y = x; -}.x - -does not terminateActually, Nix detects infinite -recursion in this case and aborts (infinite recursion -encountered).. - - - - -Let-expressions - -A let-expression allows you define local variables for an -expression. For instance, - - -let - x = "foo"; - y = "bar"; -in x + y - -evaluates to "foobar". - - - - - - -Inheriting attributes - -When defining a set it is often convenient to copy variables -from the surrounding lexical scope (e.g., when you want to propagate -attributes). This can be shortened using the -inherit keyword. For instance, - - -let x = 123; in -{ inherit x; - y = 456; -} - -evaluates to { x = 123; y = 456; }. (Note that -this works because x is added to the lexical scope -by the let construct.) It is also possible to -inherit attributes from another set. For instance, in this fragment -from all-packages.nix, - - - graphviz = (import ../tools/graphics/graphviz) { - inherit fetchurl stdenv libpng libjpeg expat x11 yacc; - inherit (xlibs) libXaw; - }; - - xlibs = { - libX11 = ...; - libXaw = ...; - ... - } - - libpng = ...; - libjpg = ...; - ... - -the set used in the function call to the function defined in -../tools/graphics/graphviz inherits a number of -variables from the surrounding scope (fetchurl -... yacc), but also inherits -libXaw (the X Athena Widgets) from the -xlibs (X11 client-side libraries) set. - - - - -Functions - -Functions have the following form: - - -pattern: body - -The pattern specifies what the argument of the function must look -like, and binds variables in the body to (parts of) the -argument. There are three kinds of patterns: - - - - - If a pattern is a single identifier, then the - function matches any argument. Example: - - -let negate = x: !x; - concat = x: y: x + y; -in if negate true then concat "foo" "bar" else "" - - Note that concat is a function that takes one - argument and returns a function that takes another argument. This - allows partial parameterisation (i.e., only filling some of the - arguments of a function); e.g., - - -map (concat "foo") [ "bar" "bla" "abc" ] - - evaluates to [ "foobar" "foobla" - "fooabc" ]. - - - A set pattern of the form - { name1, name2, …, nameN } matches a set - containing the listed attributes, and binds the values of those - attributes to variables in the function body. For example, the - function - - -{ x, y, z }: z + y + x - - can only be called with a set containing exactly the attributes - x, y and - z. No other attributes are allowed. If you want - to allow additional arguments, you can use an ellipsis - (...): - - -{ x, y, z, ... }: z + y + x - - This works on any set that contains at least the three named - attributes. - - It is possible to provide default values - for attributes, in which case they are allowed to be missing. A - default value is specified by writing - name ? - e, where - e is an arbitrary expression. For example, - - -{ x, y ? "foo", z ? "bar" }: z + y + x - - specifies a function that only requires an attribute named - x, but optionally accepts y - and z. - - - An @-pattern requires that the - argument matches with the patterns on the left- and right-hand side - of the @-sign. For example: - - -args@{ x, y, z, ... }: z + y + x + args.a - - Here args is bound to the entire argument, which - is further matches against the pattern { x, y, z, - ... }. - - - - -Note that functions do not have names. If you want to give them -a name, you can bind them to an attribute, e.g., - - -let concat = { x, y }: x + y; -in concat { x = "foo"; y = "bar"; } - - - - - - -Conditionals - -Conditionals look like this: - - -if e1 then e2 else e3 - -where e1 is an expression that should -evaluate to a Boolean value (true or -false). - - - - -Assertions - -Assertions are generally used to check that certain requirements -on or between features and dependencies hold. They look like this: - - -assert e1; e2 - -where e1 is an expression that should -evaluate to a Boolean value. If it evaluates to -true, e2 is returned; -otherwise expression evaluation is aborted and a backtrace is printed. - -Nix expression for Subversion - -{ localServer ? false -, httpServer ? false -, sslSupport ? false -, pythonBindings ? false -, javaSwigBindings ? false -, javahlBindings ? false -, stdenv, fetchurl -, openssl ? null, httpd ? null, db4 ? null, expat, swig ? null, j2sdk ? null -}: - -assert localServer -> db4 != null; -assert httpServer -> httpd != null && httpd.expat == expat; -assert sslSupport -> openssl != null && (httpServer -> httpd.openssl == openssl); -assert pythonBindings -> swig != null && swig.pythonSupport; -assert javaSwigBindings -> swig != null && swig.javaSupport; -assert javahlBindings -> j2sdk != null; - -stdenv.mkDerivation { - name = "subversion-1.1.1"; - ... - openssl = if sslSupport then openssl else null; - ... -} - - - show how assertions are -used in the Nix expression for Subversion. - - - - - This assertion states that if Subversion is to have support - for local repositories, then Berkeley DB is needed. So if the - Subversion function is called with the - localServer argument set to - true but the db4 argument - set to null, then the evaluation fails. - - - - This is a more subtle condition: if Subversion is built with - Apache (httpServer) support, then the Expat - library (an XML library) used by Subversion should be same as the - one used by Apache. This is because in this configuration - Subversion code ends up being linked with Apache code, and if the - Expat libraries do not match, a build- or runtime link error or - incompatibility might occur. - - - - This assertion says that in order for Subversion to have SSL - support (so that it can access https URLs), an - OpenSSL library must be passed. Additionally, it says that - if Apache support is enabled, then Apache's - OpenSSL should match Subversion's. (Note that if Apache support - is not enabled, we don't care about Apache's OpenSSL.) - - - - The conditional here is not really related to assertions, - but is worth pointing out: it ensures that if SSL support is - disabled, then the Subversion derivation is not dependent on - OpenSSL, even if a non-null value was passed. - This prevents an unnecessary rebuild of Subversion if OpenSSL - changes. - - - - - - - - -With-expressions - -A with-expression, - - -with e1; e2 - -introduces the set e1 into the lexical -scope of the expression e2. For instance, - - -let as = { x = "foo"; y = "bar"; }; -in with as; x + y - -evaluates to "foobar" since the -with adds the x and -y attributes of as to the -lexical scope in the expression x + y. The most -common use of with is in conjunction with the -import function. E.g., - - -with (import ./definitions.nix); ... - -makes all attributes defined in the file -definitions.nix available as if they were defined -locally in a rec-expression. - - - - -Comments - -Comments can be single-line, started with a # -character, or inline/multi-line, enclosed within /* -... */. - - - - -

Derivations - -The most important built-in function is -derivation, which is used to describe a single -derivation (a build action). It takes as input a set, the attributes -of which specify the inputs of the build. - - - - There must be an attribute named - system whose value must be a string specifying a - Nix platform identifier, such as "i686-linux" or - "powerpc-darwin"To figure out - your platform identifier, look at the line Checking for the - canonical Nix system name in the output of Nix's - configure script. The build - can only be performed on a machine and operating system matching the - platform identifier. (Nix can automatically forward builds for - other platforms by forwarding them to other machines; see .) - - There must be an attribute named - name whose value must be a string. This is used - as a symbolic name for the package by nix-env, - and it is appended to the output paths of the - derivation. - - There must be an attribute named - builder that identifies the program that is - executed to perform the build. It can be either a derivation or a - source (a local file reference, e.g., - ./builder.sh). - - Every attribute is passed as an environment variable - to the builder. Attribute values are translated to environment - variables as follows: - - - - Strings and integers are just passed - verbatim. - - A path (e.g., - ../foo/sources.tar) causes the referenced - file to be copied to the store; its location in the store is put - in the environment variable. The idea is that all sources - should reside in the Nix store, since all inputs to a derivation - should reside in the Nix store. - - A derivation causes that - derivation to be built prior to the present derivation; its - default output path is put in the environment - variable. - - Lists of the previous types are also allowed. - They are simply concatenated, separated by - spaces. - - true is passed as the string - 1, false and - null are passed as an empty string. - - - - - - The optional attribute args - specifies command-line arguments to be passed to the builder. It - should be a list. - - The optional attribute outputs - specifies a list of symbolic outputs of the derivation. By default, - a derivation produces a single output path, denoted as - out. However, derivations can produce multiple - output paths. This is useful because it allows outputs to be - downloaded or garbage-collected separately. For instance, imagine a - library package that provides a dynamic library, header files, and - documentation. A program that links against the library doesn’t - need the header files and documentation at runtime, and it doesn’t - need the documentation at build time. Thus, the library package - could specify: - -outputs = [ "lib" "headers" "doc" ]; - - This will cause Nix to pass environment variables - lib, headers and - doc to the builder containing the intended store - paths of each output. The builder would typically do something like - -./configure --libdir=$lib/lib --includedir=$headers/include --docdir=$doc/share/doc - - for an Autoconf-style package. You can refer to each output of a - derivation by selecting it as an attribute, e.g. - -buildInputs = [ pkg.lib pkg.headers ]; - - The first element of output determines the - default output. Thus, you could also write - -buildInputs = [ pkg pkg.headers ]; - - since pkg is equivalent to - pkg.lib. - - - -The function mkDerivation in the standard -environment is a wrapper around derivation that -adds a default value for system and always uses -Bash as the builder, to which the supplied builder is passed as a -command-line argument. See . - -The builder is executed as follows: - - - - A temporary directory is created under the directory - specified by TMPDIR (default - /tmp) where the build will take place. The - current directory is changed to this directory. - - The environment is cleared and set to the derivation - attributes, as specified above. - - In addition, the following variables are set: - - - - NIX_BUILD_TOP contains the path of - the temporary directory for this build. - - Also, TMPDIR, - TEMPDIR, TMP, TEMP - are set to point to the temporary directory. This is to prevent - the builder from accidentally writing temporary files anywhere - else. Doing so might cause interference by other - processes. - - PATH is set to - /path-not-set to prevent shells from - initialising it to their built-in default value. - - HOME is set to - /homeless-shelter to prevent programs from - using /etc/passwd or the like to find the - user's home directory, which could cause impurity. Usually, when - HOME is set, it is used as the location of the home - directory, even if it points to a non-existent - path. - - NIX_STORE is set to the path of the - top-level Nix store directory (typically, - /nix/store). - - For each output declared in - outputs, the corresponding environment variable - is set to point to the intended path in the Nix store for that - output. Each output path is a concatenation of the cryptographic - hash of all build inputs, the name attribute - and the output name. (The output name is omitted if it’s - out.) - - - - - - If an output path already exists, it is removed. - Also, locks are acquired to prevent multiple Nix instances from - performing the same build at the same time. - - A log of the combined standard output and error is - written to /nix/var/log/nix. - - The builder is executed with the arguments specified - by the attribute args. If it exits with exit - code 0, it is considered to have succeeded. - - The temporary directory is removed (unless the - option was specified). - - If the build was successful, Nix scans each output - path for references to input paths by looking for the hash parts of - the input paths. Since these are potential runtime dependencies, - Nix registers them as dependencies of the output - paths. - - After the build, Nix sets the last-modified - timestamp on all files in the build result to 1 (00:00:01 1/1/1970 - UTC), sets the group to the default group, and sets the mode of the - file to 0444 or 0555 (i.e., read-only, with execute permission - enabled if the file was originally executable). Note that possible - setuid and setgid bits are - cleared. Setuid and setgid programs are not currently supported by - Nix. This is because the Nix archives used in deployment have no - concept of ownership information, and because it makes the build - result dependent on the user performing the build. - - - - - - -
Advanced attributes - -Derivations can declare some infrequently used optional -attributes. - - - - allowedReferences - - The optional attribute - allowedReferences specifies a list of legal - references (dependencies) of the output of the builder. For - example, - - -allowedReferences = []; - - - enforces that the output of a derivation cannot have any runtime - dependencies on its inputs. This is used in NixOS to check that - generated files such as initial ramdisks for booting Linux don’t - have accidental dependencies on other paths in the Nix - store. - - - - - exportReferencesGraph - - This attribute allows builders access to the - references graph of their inputs. The attribute is a list of - inputs in the Nix store whose references graph the builder needs - to know. The value of this attribute should be a list of pairs - [ name1 - path1 name2 - path2 ... - ]. The references graph of each - pathN will be stored in a text file - nameN in the temporary build directory. - The text files have the format used by nix-store - --register-validity (with the deriver fields left - empty). For example, when the following derivation is built: - - -derivation { - ... - exportReferencesGraph = [ "libfoo-graph" libfoo ]; -}; - - - the references graph of libfoo is placed in the - file libfoo-graph in the temporary build - directory. - - exportReferencesGraph is useful for - builders that want to do something with the closure of a store - path. Examples include the builders in NixOS that generate the - initial ramdisk for booting Linux (a cpio - archive containing the closure of the boot script) and the - ISO-9660 image for the installation CD (which is populated with a - Nix store containing the closure of a bootable NixOS - configuration). - - - - - - outputHash - outputHashAlgo - outputHashMode - - These attributes declare that the derivation is a - so-called fixed-output derivation, which - means that a cryptographic hash of the output is already known in - advance. When the build of a fixed-output derivation finishes, - Nix computes the cryptographic hash of the output and compares it - to the hash declared with these attributes. If there is a - mismatch, the build fails. - - The rationale for fixed-output derivations is derivations - such as those produced by the fetchurl - function. This function downloads a file from a given URL. To - ensure that the downloaded file has not been modified, the caller - must also specify a cryptographic hash of the file. For example, - - -fetchurl { - url = http://ftp.gnu.org/pub/gnu/hello/hello-2.1.1.tar.gz; - md5 = "70c9ccf9fac07f762c24f2df2290784d"; -} - - - It sometimes happens that the URL of the file changes, e.g., - because servers are reorganised or no longer available. We then - must update the call to fetchurl, e.g., - - -fetchurl { - url = ftp://ftp.nluug.nl/pub/gnu/hello/hello-2.1.1.tar.gz; - md5 = "70c9ccf9fac07f762c24f2df2290784d"; -} - - - If a fetchurl derivation was treated like a - normal derivation, the output paths of the derivation and - all derivations depending on it would change. - For instance, if we were to change the URL of the Glibc source - distribution in Nixpkgs (a package on which almost all other - packages depend) massive rebuilds would be needed. This is - unfortunate for a change which we know cannot have a real effect - as it propagates upwards through the dependency graph. - - For fixed-output derivations, on the other hand, the name of - the output path only depends on the outputHash* - and name attributes, while all other attributes - are ignored for the purpose of computing the output path. (The - name attribute is included because it is part - of the path.) - - As an example, here is the (simplified) Nix expression for - fetchurl: - - -{ stdenv, curl }: # The curl program is used for downloading. - -{ url, md5 }: - -stdenv.mkDerivation { - name = baseNameOf (toString url); - builder = ./builder.sh; - buildInputs = [ curl ]; - - # This is a fixed-output derivation; the output must be a regular - # file with MD5 hash md5. - outputHashMode = "flat"; - outputHashAlgo = "md5"; - outputHash = md5; - - inherit url; -} - - - - - The outputHashAlgo attribute specifies - the hash algorithm used to compute the hash. It can currently be - "md5", "sha1" or - "sha256". - - The outputHashMode attribute determines - how the hash is computed. It must be one of the following two - values: - - - - "flat" - - The output must be a non-executable regular - file. If it isn’t, the build fails. The hash is simply - computed over the contents of that file (so it’s equal to what - Unix commands like md5sum or - sha1sum produce). - - This is the default. - - - - "recursive" - - The hash is computed over the NAR archive dump - of the output (i.e., the result of nix-store - --dump). In this case, the output can be - anything, including a directory tree. - - - - - - - - The outputHash attribute, finally, must - be a string containing the hash in either hexadecimal or base-32 - notation. (See the nix-hash command - for information about converting to and from base-32 - notation.) - - - - - impureEnvVars - - This attribute allows you to specify a list of - environment variables that should be passed from the environment - of the calling user to the builder. Usually, the environment is - cleared completely when the builder is executed, but with this - attribute you can allow specific environment variables to be - passed unmodified. For example, fetchurl in - Nixpkgs has the line - - -impureEnvVars = [ "http_proxy" "https_proxy" ... ]; - - - to make it use the proxy server configuration specified by the - user in the environment variables http_proxy and - friends. - - This attribute is only allowed in fixed-output derivations, where - impurities such as these are okay since (the hash of) the output - is known in advance. It is ignored for all other - derivations. - - - - - preferLocalBuild - - If this attribute is set to - true, it has two effects. First, the - derivation will always be built, not substituted, even if a - substitute is available. Second, if distributed building is - enabled, then, if possible, the derivaton will be built - locally instead of forwarded to a remote machine. This is - appropriate for trivial builders where the cost of doing a - download or remote build would exceed the cost of building - locally. - - - - - -

The standard environment - - -The standard environment is used by passing it as an input -called stdenv to the derivation, and then doing - - -source $stdenv/setup - -at the top of the builder. - -Apart from adding the aforementioned commands to the -PATH, setup also does the -following: - - - - All input packages specified in the - buildInputs environment variable have their - /bin subdirectory added to PATH, - their /include subdirectory added to the C/C++ - header file search path, and their /lib - subdirectory added to the linker search path. This can be extended. - For instance, when the pkgconfig package is - used, the subdirectory /lib/pkgconfig of each - input is added to the PKG_CONFIG_PATH environment - variable. - - The environment variable - NIX_CFLAGS_STRIP is set so that the compiler strips - debug information from object files. This can be disabled by - setting NIX_STRIP_DEBUG to - 0. - - - - - -The setup script also exports a function -called genericBuild that knows how to build -typical Autoconf-style packages. It can be customised to perform -builds for any type of package. It is advisable to use -genericBuild since it provides facilities that -are almost always useful such as unpacking of sources, patching of -sources, nested logging, etc. - -The definitive, up-to-date documentation of the generic builder -is the source itself, which resides in -pkgs/stdenv/generic/setup.sh. - - -
Customising the generic builder - -The operation of the generic builder can be modified in many -places by setting certain variables. These hook -variables are typically set to the name of some shell -function defined by you. For instance, to perform some additional -steps after make install you would set the -postInstall variable: - - -postInstall=myPostInstall - -myPostInstall() { - mkdir $out/share/extra - cp extrafiles/* $out/share/extra -} - - - - -
- - -
Debugging failed builds - -At the beginning of each phase, the set of all shell variables -is written to the file env-vars at the top-level -build directory. This is useful for debugging: it allows you to -recreate the environment in which a build was performed. For -instance, if a build fails, then assuming you used the - flag, you can go to the output directory and -switch to the environment of the builder: - - -$ nix-build -K ./foo.nix -... fails, keeping build directory `/tmp/nix-1234-0' - -$ cd /tmp/nix-1234-0 - -$ source env-vars - -(edit some files...) - -$ make - -(execution continues with the same GCC, make, etc.) - - - -
