Eelco Dolstra 1a211d812f * Oops. 2010-11-17 17:54:49 +00:00
Eelco Dolstra a4f0365b2d * When checking whether a patch is applicable, for efficiency, use 
`nix-store -q --hash' to get the hash of the base path rather than
  `nix-hash'.  However, only do this for estimating the size of a
  download, not for the actual substitution, because sometimes the
  contents of store paths are modified (which they shouldn't, of
  course).
 2010-11-17 17:41:59 +00:00
Eelco Dolstra 3d38a49840 * In the download size indication, take binary patches into account. 
Hopefully this doesn't slow things down too much.
 2010-11-17 17:32:25 +00:00
Eelco Dolstra bdf089f463 * Before a build, show the disk space that the downloaded store paths 
will approximately require.
 2010-11-17 14:31:42 +00:00
Eelco Dolstra 719cebcac2 * "Fix" incorrect help message. 2010-02-04 09:38:09 +00:00
Eelco Dolstra e839802720 * Don't do a chdir to $tmpDir. It's not necessary, and Windows doesn't 
support deleting the current directory.
 2010-02-02 15:29:18 +00:00
Eelco Dolstra 7e05b8b75e * Future proofing: assume we can read manifests up to version 10 
(which should therefore be backwards compatible).
 2009-03-19 10:02:02 +00:00
Eelco Dolstra 1273d355ac * nix-install-package: don't pollute /nix/var/nix/manifests. 2009-02-27 14:06:38 +00:00
Eelco Dolstra a7cee528c5 * Handle base-16 hashes in manifests. 2009-02-26 21:12:35 +00:00
Eelco Dolstra 041717eda3 * download-using-manifests: don't check the cryptographic hash of 
downloaded files; rather, check the hash of the unpacked store
  path.

  When the server produces bzipped NAR archives on demand (like Hydra
  does), the hash of the file is not known in advance; it's streamed
  from the server.  Thus the manifest doesn't contain a hash for the
  bzipped NAR archive.  However, the server does know the hash of the
  *uncompressed* NAR archive (the "NarHash" field), since it's stored
  in the Nix database (nix-store -q --hash /nix/store/bla).  So we use
  that instead for checking the integrity of the download.

Eelco Dolstra 4213b8d8ec * Urgh. 2008-11-20 15:44:59 +00:00
Eelco Dolstra 2b2aa8a820 * Doh. 2008-09-08 11:02:15 +00:00
Eelco Dolstra 42043953c3 * Doh. 2008-08-04 13:15:47 +00:00
Eelco Dolstra 3c92ea399d * Make nix-env --dry-run print the paths to be substituted correctly 
again.  (After the previous substituter mechanism refactoring I
  didn't update the code that obtains the references of substitutable
  paths.)  This required some refactoring: the substituter programs
  are now kept running and receive/respond to info requests via
  stdin/stdout.
 2008-08-02 12:54:35 +00:00
Eelco Dolstra 989176c56e * Allow read-only access to the store (e.g., non-root users on NixOS 
can do operations like "nix-store -qR <path>" even without the Nix
  daemon).
 2008-07-18 15:34:46 +00:00
Eelco Dolstra f8ed2e64a5 2007-10-22 12:05:18 +00:00
Eelco Dolstra 9e975458b4 * Get rid of the substitutes database table (NIX-47). Instead, if we 
need any info on substitutable paths, we just call the substituters
  (such as download-using-manifests.pl) directly.  This means that
  it's no longer necessary for nix-pull to register substitutes or for
  nix-channel to clear them, which makes those operations much faster
  (NIX-95).  Also, we don't have to worry about keeping nix-pull
  manifests (in /nix/var/nix/manifests) and the database in sync with
  each other.

  The downside is that there is some overhead in calling an external
  program to get the substitutes info.  For instance, "nix-env -qas"
  takes a bit longer.

  Abolishing the substitutes table also makes the logic in
  local-store.cc simpler, as we don't need to store info for invalid
  paths.  On the downside, you cannot do things like "nix-store -qR"
  on a substitutable but invalid path (but nobody did that anyway).

* Never catch interrupts (the Interrupted exception).
 2007-08-12 00:29:28 +00:00
Eelco Dolstra bae75ca5a1 * New kind of manifest object: "localPath", which denotes that a store 
path can be created by copying it from another location in the file
  system.  This is useful in the NixOS installation.
 2007-01-23 16:50:19 +00:00
Eelco Dolstra 36d9258c0d * Successors have been gone for ages. 2007-01-23 16:05:59 +00:00
Eelco Dolstra 215505bb46 * Removed chroot support. 2007-01-13 17:54:01 +00:00
Eelco Dolstra d98f750fd8 * tmpnam() -> File::Temp::tempdir(). 2006-10-04 18:58:11 +00:00
Eelco Dolstra 68ae953d8a * Clean up calls to system(). 2006-09-25 10:44:27 +00:00
Armijn Hemel f1947cce93 prevent doing recursive chroots, by unsetting NIX_ROOT in the scripts. 2006-08-05 00:31:04 +00:00
Eelco Dolstra 981eff065b * Remove the dependency on `date', use strftime instead. 2006-08-04 11:45:50 +00:00
Eelco Dolstra 846b53bde4 * Set the current directory to something well-defined. Might help in 
setuid installations.
 2005-09-16 09:03:24 +00:00
Eelco Dolstra 7f384d9c1b * Use a proper temporary directory. 2005-09-15 15:21:35 +00:00
Eelco Dolstra cbc8d083ac * Make unpacking of patch sequences much faster by not doing redundant 
unpacking and repacking of intermediate paths.
 2005-05-10 14:22:36 +00:00
Eelco Dolstra 9f3601a36c * Argh! The patch downloader was broken due to the renaming of the 
`--isvalid' flag in nix-store.
 2005-04-12 10:51:38 +00:00
Eelco Dolstra ebe342c9c1 * Better error checking. 2005-03-25 14:30:01 +00:00
Eelco Dolstra 6fb5f7e532 * Pass `--base32' unless using MD5. 2005-03-14 18:55:29 +00:00
Eelco Dolstra bb2e53699f * Parse new hash format properly. 2005-03-14 17:05:42 +00:00
Eelco Dolstra 8376fff151 * Add a version number to manifests. 2005-02-25 16:12:52 +00:00
Eelco Dolstra 3259ae5811 * Properly specify the hash algorithm in the manifests, and read it 
too.
* Change the default hash for nix-prefetch-url back to md5, since
  that's what we use in Nixpkgs (for now; a birthday attack is rather
  unlikely there).
 2005-02-24 17:36:42 +00:00
Eelco Dolstra 066da4ab85 * Really fix the substitute mechanism, i.e., ensure the closure 
invariant by registering references through the manifest.
* Added a test for nix-pull.
 2005-01-25 17:08:52 +00:00
Eelco Dolstra 9ee88bb2f2 * Use absolute paths. 2005-01-14 13:50:00 +00:00
Eelco Dolstra 0bc41f632b * Print out less garbage. 2005-01-12 10:37:18 +00:00
Eelco Dolstra 35b76a81c4 * More instrumentation (statistics go to /nix/var/log/nix/downloads). 2004-12-30 17:19:47 +00:00
Eelco Dolstra 3745cecc6a * Fix handling of chained patches: don't skip patches if intermediate 
paths are missing, etc.
 2004-12-30 17:09:57 +00:00
Eelco Dolstra 581bcb986f * Some logging for evaluation. 2004-12-30 16:34:54 +00:00
Eelco Dolstra 6270aa727d * Propagate patches from the source distribution to the destination 
distribution insofar they are applicable.
 2004-12-29 22:17:26 +00:00
Eelco Dolstra 3d1b2101cc * Place manifests in /nix/var/nix/manifests. 
* Use the new patch downloader.
