* guix/build/syscalls.scm (<mount>): New record type.
(option-string->mount-flags, mount-flags)
(octal-decode, mounts): New procedures.
(mount-points): Rewrite in terms of 'mount'.
* tests/syscalls.scm ("mounts"): New test.
Fixes <https://bugs.gnu.org/46362>.
Reported by Zhu Zihao <all_but_last@163.com>.
Previously, backtraces due to uncaught exceptions would always to go
file descriptor 2; the daemon would read it and error out with something
like:
error: got unexpected path `Backtrace:' from substituter
This patch fixes that by ensuring backtraces are properly displayed on
file descriptor 4.
* guix/scripts/substitute.scm (with-redirected-error-port): New macro.
(guix-substitute): Use 'with-redirected-error-port' instead of 'parameterize'.
This prevents generated launchers and desktop files from inadvertently
crashing if the directory name contains a space.
* gnu/build/renpy-build-system.scm (install, install-desktop-file): Use ~s
to format data directory.
This avoids a closure allocation when 'lookup-cached-object' is called.
* guix/store.scm (lookup-cached-object): Avoid optional/keyword
arguments and inline.
(%mcached): Adjust accordingly.
This reduces the total amount of memory allocated by 8% when running
"guix build qemu -d --no-grafts".
* guix/gexp.scm (fold/tree): New procedure.
(gexp-inputs)[interesting?]: New procedure.
[add-reference-inputs]: Change (lst ...) clause to (? pair? lst), and
use 'fold/tree' to recurse into it.
(gexp-inputs)[add-reference-output]: Likewise, and remove
plain (lst ...) clause.
Call 'fold'.
(gexp->sexp)[reference->sexp]: In the list case, avoid boxing and
recursive call when the object has a plain non-aggregate type.
This avoids double traversal of references and extra bookkeeping,
thereby further reducing memory allocations.
* guix/gexp.scm (lower-gexp): Include only one call to 'lower-inputs'.
(gexp-inputs): Remove #:native? parameter.
[set-gexp-input-native?]: New procedure.
[add-reference-inputs]: Use it.
(gexp-native-inputs): Remove.
* tests/gexp.scm (gexp-native-inputs): Remove.
(gexp-input->tuple): Include 'gexp-input-native?'.

("let-system, nested")

("input list")
("input list + ungexp-native")
("input list splicing")
("input list splicing + ungexp-native-splicing")
("gexp list splicing + ungexp-splicing"): Adjust accordingly.
This slightly reduces memory allocation.
* guix/gexp.scm (lower-inputs): Expect a list of <gexp-input> rather
than a list of tuples.
(lower-reference-graphs)[tuple->gexp-input]: New procedure.
Use it.
(gexp-inputs): Return a list of <gexp-input> rather than a list of
tuples.
* tests/gexp.scm (gexp-input->tuple): New procedure.

Previously, 'guix install foo -r bar' would crash with a backtrace
because NAME would be #\r (a character instead of a string).
* guix/scripts.scm (parse-command-line)[parse-options-from]: Call
'option-hint' only when NAME is a string.
This is part of trying to reduce the interdependency of code within the
substitute module.
This commit addresses some of the error handling that was performed through
open-connection-for-uri/maybe. The new approach is to use
call-with-connection-error-handling, and wrap calls to http-multiple-get and
http-fetch with that procedure, which takes care of handling connection
errors.
I think this is even slightly more rigerous than the previous setup, because
this approach handles connection errors that occur when http-multiple-get
reconnects to a host.
* guix/scripts/substitute.scm (open-connection-for-uri/maybe): Transform in to
call-with-connection-error-handling.
(fetch-narinfos): Use call-with-connection-error-handling.
(process-query): Replace open-connection-for-uri/maybe with
open-connection-for-uri/cached.
(open-connection-for-uri/cached): Set a default timeout, matching the
behaviour in open-connection-for-uri/maybe.
(process-substitution): Use call-with-connection-error-handling.
At least by default. Instead, make the open-connection procedure a parameter,
and make the default guix:open-connection-for-uri. Do so similarly for
lookup-narinfos and lookup-narinfos/diverse which work towards calling
fetch-narinfos.
This means this code can be moved to a different module, without having
use/move the connection caching code.
* guix/scripts/substitute.scm (fetch-narinfos): Add #:open-connection
argument, and call http-multiple-get with it.
(lookup-narinfos) Add #:open-connection argument, and call fetch-narinfos with
it.
(lookup-narinfos/diverse): Add #:open-connection argument, and call
lookup-narinfos with it.
(process-query): Call lookup-narinfos/diverse with #:open-connection
open-connection-for-uri/maybe.
As it's only called in one place, and this should make the code easier to
read.
* guix/scripts/substitute.scm (fetch): Move procedure inside…
(process-substitution): …here.
It's just called in one place, with hardcoded argument values, so just inline
them.
* guix/scripts/substitute.scm (fetch): Remove arguments that don't vary, copy
the values from the call site in process-substitution.
(process-substitution): Remove unnecessary argument values from fetch call.
Failures now should be handled where they occur, and if there's a problem
that's symptomatic of an issue with the connection, the port should be closed.
* guix/scripts/substitute.scm (call-with-cached-connection): Remove procedure.
(with-cached-connection): Remove syntax rule.
Just pass open-connection-for-uri/maybe to http-fetch, this removes the need
for with-cached-connection and passing the port in.
* guix/scripts/substitute.scm (fetch): Don't take a port as an argument, and
pass open-connection-for-uri/maybe to http-fetch.
(process-substitution): Don't call fetch with with-cached-connection.
So that an alternative procedure can be passed in, perhaps to perform
connection caching.
* guix/http-client.scm (http-fetch): Add an #:open-connection keyword
argument.
Instead, just pass open-connection-for-uri/maybe to http-multiple-get. This
code should be functionaly similar to the previous code. The eventual aim of
this is to make the connection caching not mandatory in fetch-narinfos.
* guix/scripts/substitute.scm (fetch-narinfos): Remove use of
call-with-cached-connection.
As this is used by http-fetch and http-multiple-get when they call the
specified open connection procedure.
* guix/scripts/substitute.scm (open-connection-for-uri/maybe): Support
#:verify-certificate?.
Making sure to close the port if it looks to be unusable. This closing of the
port will allow for caching connections, without caching broken connections,
as the cache can avoid handing out closed ports.
* guix/http-client.scm (http-multiple-get): Try to catch exceptions that
happen if the port is unusable, this is a adaptation of code within the (guix
scripts substitute) module.
From (guix scripts substitute). This will make it easier to reuse this code.
* guix/scripts/substitute.scm (http-multiple-get): Remove, and move to…
* guix/http-client.scm (http-multiple-get): …here.
Fixes <https://bugs.gnu.org/46390>.
Reported by zimoun <zimon.toutoune@gmail.com>.
This is similar to the fix in d10474c38d.
* guix/packages.scm (package-field-location): Handle FILE not in %LOAD-PATH.
* tests/guix-lint.sh: Add test.
Remove the 'vm-image' command that has been superseded by the 'image'
command.
* gnu/system/vm.scm (system-qemu-image): Remove it.
* guix/scripts/system.scm (system-derivation-for-action): Mark 'vm-image'
command as deprecated and use the image API to produce the VM image.
(perform-action, show-help): Adapt accordingly.
* tests/guix-system.sh: Ditto.
* doc/guix.texi (Invoking guix system,
Running Guix in a VM): Ditto.
* etc/completion/fish/guix.fish: Ditto.
* etc/completion/zsh/_guix: Ditto.
This fixes <https://bugs.gnu.org/46481>.
* guix/ftp-client.scm (ftp-epsv, ftp-passive): New procedures.
(ftp-list, ftp-retr): Replace call to 'ftp-pasv' with 'ftp-passive'.
* guix/import/crate.scm (make-crate-sexp): Always use home-page, which is
properly set up by the caller.
(crate->guix-package): Make sure to use the repository when home-page is null.
Fixes a regression introduced in
316fc2acbb, whereby 'guix pull -l' would
always display channel information corresponding to the latest profile
generation.
Reported by Vagrant Cascadian.
* guix/scripts/describe.scm (profile-generation-channels): New
procedure.
(display-profile-content): Change default value of 'channels'.
