2023-06-18Add 'guix locate'.Ludovic Courtès
* guix/scripts/locate.scm, tests/guix-locate.sh: New files. * Makefile.am (MODULES): Add 'guix/scripts/locate.scm'. (SH_TESTS): Add 'tests/guix-locate.sh'. * po/guix/POTFILES.in: Add it. * doc/guix.texi (Invoking guix locate): New node. Co-authored-by: Antoine R. Dumont <antoine.romain.dumont@gmail.com>
2023-06-16guix home: Add missing SRFI-34 import for 'raise'.Ludovic Courtès
Reported at <https://issues.guix.gnu.org/64031>. * guix/scripts/home.scm: Use (srfi srfi-34), expected by 'list-generations'. Reported-by: Steven Roose <steven@roose.io>
2023-06-16pull: Preserve channel ordering when using '--commit', '--url', etc.Ludovic Courtès
Previously using '--url', '--commit', or '--branch' would move the 'guix' channel to the front. This is okay in itself but it gratuitously leads to a different cache key in 'cached-channel-instance'--IOW, 'guix time-machine --commit=X' where X is already in cache would gratuitously recompute the channel derivations. * guix/scripts/pull.scm (channel-list): Use 'map' instead of 'find' + 'remove' + 'cons'.
2023-06-08substitute: Gracefully retry after failed partial downloads.Ludovic Courtès
Fixes <https://issues.guix.gnu.org/63443>. Reported by Attila Lendvai <attila@lendvai.name>. * guix/scripts/substitute.scm (catch-system-error): New macro. (download-nar): Add call to 'delete-file-recursively'. * tests/substitute.scm ("substitute, previous partial download around"): New test.
2023-06-08substitute: Delete cached narinfos more than two-month old.Ludovic Courtès
This allows 'guix substitute' to shrink the cache a bit more, which saves space and improves performance of cache-cleanup phases since fewer entries need to be traversed. * guix/scripts/substitute.scm (cached-narinfo-expiration-time): Define 'max-ttl' and use it as an upper bound.
2023-06-08import: Gracefully handle EPIPE.Ludovic Courtès
Previously, "guix import pypi f3 | head -3" would print a backtrace. * guix/scripts/import.scm (guix-import): Wrap 'pretty-print-with-comments' call in 'leave-on-EPIPE'.
2023-06-02environment: Fix unbound-variable bug with '--symlink'.Ludovic Courtès
Fixes <https://issues.guix.gnu.org/63845>. Reported by Maxim Cournoyer <maxim.cournoyer@gmail.com>. * guix/scripts/environment.scm (launch-environment/container): Reference 'evaluate-populate-directive' before calling 'call-with-container'.
2023-05-31upstream: 'update-package-source' edits input fields.Ludovic Courtès
Previously, 'guix refresh r-ggplot2 -u' and similar commands would print of list of input changes that would have to be made manually. With this change, 'guix refresh -u' takes care of updating input fields automatically. * guix/upstream.scm (update-package-inputs): New procedure. (update-package-source): Call it when 'upstream-source-inputs' returns true. * guix/scripts/refresh.scm (update-package): Remove iteration over the result of 'changed-inputs'. * guix/import/test.scm (available-updates): Add support for input lists. * tests/guix-refresh.sh (GUIX_TEST_UPDATER_TARGETS): Add input list for "the-test-package". Make sure 'guix refresh -u' updates 'inputs' accordingly. * doc/guix.texi (Invoking guix refresh): Mention it.

2023-05-31upstream: Replace 'input-changes' field by 'inputs'.Ludovic Courtès
Returning the expected list of inputs rather than changes relative to the current package definition is less ambiguous and offers more possibilities for further processing. * guix/upstream.scm (<upstream-source>)[input-changes]: Remove. [inputs]: New field. (<upstream-input>): New record type. * guix/upstream.scm (upstream-input-type-predicate) (input-type-filter, upstream-source-regular-inputs) (upstream-source-native-inputs, upstream-source-propagated-inputs): New procedures.

2023-05-30substitute: If a server's nar URL is 404, try the next one(s).Ludovic Courtès
If a substitute server advertises in its narinfo, for example, both a /zstd and a /lzip URL but the /zstd URL is unreachable, try the /lzip URL. Fixes <https://issues.guix.gnu.org/63634>. * guix/narinfo.scm (narinfo-preferred-uris): New procedure. (narinfo-best-uri): Rebase on top of it. * guix/scripts/substitute.scm (download-nar)[try-fetch]: New procedure. Use 'narinfo-preferred-uris' and 'try-fetch' to attempt all the URLs of NARINFO. * tests/substitute.scm (request-substitution): Remove 'parameterize'. Delete DESTINATION. ("substitute, preferred nar URL is 404, other is 200"): New test.
2023-05-22substitute: Rethrow with 'raise-exception', not 'throw'.Ludovic Courtès
Rethrowing with 'throw' doesn't work as intended when the exception being rethrown is a SRFI-34 exception. Fixes <https://issues.guix.gnu.org/55820>. * guix/scripts/substitute.scm (kind-and-args-exception?): New variable. (call-with-cached-connection): Rewrite using 'guard' instead of 'catch' and 'raise' instead of 'throw'. (system-error?): Use 'kind-and-args-exception?' instead of local definition.
2023-05-18style: Add 'arguments' styling rule.Ludovic Courtès
* guix/scripts/style.scm (unquote->ungexp, gexpify-argument-value) (quote-argument-value, gexpify-argument-tail) (gexpify-package-arguments): New procedures. (%gexp-keywords): New variable.

(Invoking guix style): Document the 'arguments' styling rule.
2023-05-18refresh: Honor '--key-server'.Ludovic Courtès
Previously, the '--key-server' option would be ignored in an invocation like: ./pre-inst-env guix refresh python-scipy=1.8.1 -t pypi -u \ --key-server=pgp.mit.edu * guix/upstream.scm (download-tarball): Add #:key-server parameter and pass it to 'gnupg-verify*'.

2023-05-04style: Make 'safe' policy less conservative.Ludovic Courtès
Previously, a mere (arguments '(#:tests? #f)) would lead guix style -S inputs --input-simplification=safe to bail out. It now recognizes such trivial argument lists and proceeds. * guix/scripts/style.scm (trivial-package-arguments?): New procedure.

2023-02-27ui: 'display-hint' quotes extra arguments for Texinfo.Ludovic Courtès
Fixes <https://issues.guix.gnu.org/61201>. Previously, common practice was to splice arbitrary strings (user names, file names, etc.) into Texinfo snippets passed to 'display-hint'. This is unsafe in the general case because at signs and braces need to be escaped to produced valid Texinfo. This commit addresses that. * guix/ui.scm (texinfo-quote): New procedure.

Commit 68380db4c40a2ee1156349a87254fd7b1f1a52d5 moved from 'gexp->derivation', which as a side effect, would lead tests to require a "world rebuild"--specifically, they'd have to build (default-guile). This was mitigated by 68775338a510f84e63657ab09242d79e726fa457, but that change introduced another regression. * guix/scripts/pack.scm (populate-profile-root): Define 'bootstrap?'.

2023-01-16guix graph: '--path' defaults to "out" in the case of multiple outputs.Ludovic Courtès
Previously, "guix graph -t references --graph guix guile" would fail with: no path from '/gnu/store/…-guix-1.4.0-1.9fe5b49' to '/gnu/store/…-guile-3.0.8-debug' simply because the "debug" happened to be the first one, getting bound to NODE2.

2023-01-16guix graph: 'guix graph --path' correctly handles multiple outputs.Ludovic Courtès
Previously, "guix graph -t references --path guix guile" would fail with: error: '--path' option requires exactly two nodes (given 2) This is because '_' in the 'match' clause wouldn't match the placeholder and would instead be interested as a variable name, thereby meaning NODES is expected to have two lists with the same tail. * guix/scripts/graph.scm (guix-graph): Rename '_' in 'mlet' to '_g' so that the literal '_' used in 'match' below matches.
