2019-07-19channels: Remove unneeded 'version' field of <channel-metadata>.Ludovic Courtès
The idea is that 'read-channel-metadata' will take care of converting possibly older versions to the current data type. Thus, storing the version number is unnecessary. * guix/channels.scm (<channel-metadata>)[version]: Remove. (read-channel-metadata, channel-instance-dependencies): Adjust accordingly.
2019-07-19channels: Strictly check the version of '.guix-channel'.Ludovic Courtès
Until now the 'version' field in '.guix-channel' could be omitted, or it could be any value. * guix/channels.scm (read-channel-metadata): Rename to... (channel-instance-metadata): ... this. (channel-instance-dependencies): Adjust accordingly. (read-channel-metadata): New procedure. Use 'match' to require a 'version' field. Provide proper error handling when the channel sexp is malformed or when given an unsupported version number. (read-channel-metadata-from-source): Use 'catch' and 'system-error-errno' instead of 'file-exists?'. * tests/channels.scm (instance--unsupported-version): New variable. (read-channel-metadata): Rename to... (channel-instance-metadata): ... this. Rename tests accordingly. ("channel-instance-metadata rejects unsupported version"): New test.
2019-07-15channels: Avoid use of 'derivation-input-path'.Ludovic Courtès
* guix/channels.scm (old-style-guix?): Use 'derivation-name' rather than 'derivation-input-path'.
2019-07-14channels: Add optional directory to channel metadata.Jan Nieuwenhuizen
* guix/channels.scm (<channel-metadata>): Add directory slot. Update users. (read-channel-metadata-from-source): New function. (standard-module-derivation): Use it. * doc/guix.texi (Package Modules in a Subdirectory): New subsection.
2019-07-08channels: Key cached channel derivations by system.Ludovic Courtès
Previously, the channel instance to derivation mapping would be independent of the system. Thus, building the same channel instance for several different systems would always return the derivation that was first computed. This is a followup to c3ab921eed2a471022e9863a94ea521508782e53. * guix/channels.scm (channel-instance-derivations)[instance->derivation]: Pass the current system as a third argument to 'mcached'.
2019-07-06channels: Simplify 'channel-instances->manifest'.Ludovic Courtès
* guix/channels.scm (channel-instances->manifest)[instance->entry]: Change to take two arguments instead of a tuple. Turn into a non-monadic procedure. Call it via 'map' instead of 'mapm'.
2019-06-03deprecation: Use the 'warning' procedure for diagnostics.Ludovic Courtès
Until now, (guix deprecation) had its own warning mechanism, which was inconsistent (it did not use colors, etc.) * guix/deprecation.scm (deprecation-warning-port): Remove (source-properties->location-string): Remove. (warn-about-deprecation): Use 'warning' instead of 'format'. (define-deprecated, define-deprecated/alias): Adjust docstring. * guix/channels.scm (build-from-source): Refer to 'guix-warning-port' instead of 'deprecation-warning-port'.
2019-04-17pull: '--url', '--commit', and '--branch' apply to the 'guix' channel.Ludovic Courtès
Suggested by pkill9 <pkill9@runbox.com>. * guix/scripts/pull.scm (channel-list): Apply REF and URL to the 'guix' channel. * doc/guix.texi (Invoking guix pull): Adjust accordingly.
2019-03-08channels: Do not fail when the inferior lacks 'guix repl'.Ludovic Courtès
Fixes <https://bugs.gnu.org/34637>. Reported by Martin Flack <martin.flack@gmail.com>. Previously we'd fail to build the package cache for old versions of Guix that lack 'guix repl'. Now we simply ignore the issue and keep going without a cache. * guix/inferior.scm (gexp->derivation-in-inferior): Add #:silent-failure? and honor it. [drop-extra-keyword]: New procedure. Use it. * guix/channels.scm (package-cache-file): Pass #:silent-failure? #t.
2019-01-29channels: Do not offload package cache derivation.Ludovic Courtès
* guix/channels.scm (package-cache-file): Pass #:local-build? to 'gexp->derivation-in-inferior'.
2019-01-28channels: Turn off deprecation warnings when loading 'build-self.scm'.Ludovic Courtès
* guix/channels.scm (build-from-source): Parameterize DEPRECATION-WARNING-PORT when loading SCRIPT.
2019-01-20channels: Use 'fold2'.Ludovic Courtès
* guix/channels.scm (latest-channel-instances): Use 'fold2' instead of 'fold'.
2019-01-20channels: Gracefully report the lack of a 'guix' channel.Ludovic Courtès
* guix/channels.scm (channel-instance-derivations): Raise an '&message' condition when CORE-INSTANCE is #f.
2019-01-20channels: Build channel modules in an inferior.Ludovic Courtès
This ensures that channel modules are compiled with the right Guile, that they get to see the right modules, and so on. IOW, it avoids bugs such as those addressed by commits 3c0e16391ed9a3e3e4611b940fb393c5f2ecea63 and cb341c121919877ae6267a6460c0c17536d06eff. * guix/channels.scm (standard-module-derivation): Add 'core' parameter. Rewrite in terms of 'gexp->derivation-in-inferior'. (build-from-source): Add #:core parameter and pass it to 'standard-module-derivation'. (build-channel-instance): Add 'core' parameter and pass it on. (channel-instance-derivations)[dependencies]: Remove. Adjust 'build-channel-instance' call.
2019-01-20channels: Don't pull from the same channel more than once.Ludovic Courtès
Previous 'channel-instance->manifest' would call 'latest-channel-derivation', which could trigger another round of 'latest-repository-commit' for no good reason. * guix/channels.scm (resolve-dependencies): New procedure. (channel-instance-derivations)[edges]: New variable. [instance->derivation]: New procedure. * tests/channels.scm (make-instance): Use 'checkout->channel-instance' instead of 'channel-instance'. ("channel-instances->manifest"): New test.
2019-01-15channels: Compute a package cache and use it.Ludovic Courtès
* gnu/packages.scm (cache-is-authoritative?, load-package-cache) (cache-lookup, generate-package-cache): New procedures. (%package-cache-file): New variable. (find-packages-by-name): Rename to... (find-packages-by-name/direct): ... this. (find-packages-by-name): Rewrite to use the package cache when 'cache-is-authoritative?' returns true. * tests/packages.scm ("find-packages-by-name + version, with cache") ("find-packages-by-name with cache"): New tests. * guix/channels.scm (package-cache-file): New procedure. (%channel-profile-hooks): New variable. (channel-instances->derivation): Use it in #:hooks. * guix/scripts/package.scm (build-and-use-profile): Add #:hooks and honor it. * guix/scripts/pull.scm (build-and-install): Pass #:hooks to UPDATE-PROFILE.
2019-01-07self: Move all modules into a single directory.Ludovic Courtès
This halves the number of elements in %LOAD-PATH and %LOAD-COMPILED-PATH and halves the number of 'stat' calls as reported by: env -i $(type -P guix) build -e '(@ (gnu packages base) coreutils)' -nd * guix/self.scm (node-source+compiled, guile-module-union): New procedures. (guix-command): Remove 'compiled-modules' parameter. Remove 'source-directories' and 'object-directories' variables and add 'module-directory'. Change command so that it adds nothing but MODULE-DIRECTORY to %LOAD-PATH and %LOAD-COMPILED-PATH. (whole-package): Remove #:compiled-modules. Assume MODULES contains 'share/guile/site' and 'lib/guile' and adjust code accordingly. (compiled-guix): When PULL-VERSION is 1, use 'node-source+compiled' only. Remove #:compiled-modules argument to 'whole-package'. * guix/channels.scm (whole-package-for-legacy): Add 'module+compiled' and pass it to 'whole-package'.
2018-12-09guix: Add support for channel dependencies.Ricardo Wurmus

2018-09-16channels: Add Guile-Git as a dependency of external channels.Ludovic Courtès
Fixes a regression introduced in aed0a594058a59bc3bb1d2686391dc0e8a181b1f whereby external channels would fail to build due to the lack of a (git) module. Reported by Alex ter Weele on #guix. * guix/channels.scm (channel-instance-derivations)[guile-gcrypt]: Remove. [dependencies]: New variable. Use it in the 2nd argument to 'build-channel-instance'.
2018-09-05git: Don't require users to specifiy "origin/" for branches.Ludovic Courtès
Fixes <https://bugs.gnu.org/32618>. Reported by Eric Brown <brown@fastmail.com>. * guix/git.scm (update-cached-checkout): Remove "origin/" from default REF. Define CANONICAL-REF and use it instead of REF. (latest-repository-commit): Remove "origin/" from default REF. * guix/channels.scm (%default-channels): Remove "origin/" from 'branch'.
