* 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.
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'.
* guix/channels.scm (<channel-metadata>): New record.
(read-channel-metadata, channel-instance-dependencies): New procedures.
(latest-channel-instances): Include channel dependencies; add optional
argument PREVIOUS-CHANNELS.
(channel-instance-derivations): Build derivation for additional channels and
add it as dependency to the channel instance derivation.
* doc/guix.texi (Channels): Add subsection "Declaring Channel Dependencies".
* tests/channels.scm: New file.
* Makefile.am (SCM_TESTS): Add it.
Fixes a regression introduced in
aed0a59405 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'.
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'.
This fixes a regression introduced in
ca71942445 whereby external channels would
fail to build due to the lack of (gcrypt …) modules.
* guix/channels.scm (channel-instance-derivations): Add 'guile-gcrypt'.
Pass it along CORE to 'build-channel-instance'.
* guix/channels.scm: New file.
* Makefile.am (MODULES): Add it.
* guix/scripts/pull.scm: Use it.
(%default-options): Remove 'repository-url' and 'ref'.
(show-help, %options): Add '--channels'.
(%self-build-file, %pull-version, build-from-source)
(whole-package-for-legacy, derivation->manifest-entry): Remove. These
now exist in a similar form in (guix channels).
(build-and-install): Change 'source' to 'instances'. Remove #:url,
#:branch, and #:commit. Rewrite using 'channel-instances->manifest'.
(channel-list): New procedure.
(guix-pull): Parameterize %REPOSITORY-CACHE-DIRECTORY. Call
'honor-lets-encrypt-certificates!' unconditionally. Load
~/.config/guix/channels.scm. Rewrite to use (guix channels).
[use-le-certs?]: Remove.
* po/guix/POTFILES.in: Add (guix channels).
* doc/guix.texi (Invoking guix pull): Group the description of '--url',
'--commit', and '--branch'. Remove mention of 'GUIX_PULL_URL'. Add
references to "Channels". Document '--channels'.
(Channels): New node.
(Defining Packages): Link to "Channels" instead of "Package Modules".
(Invoking guix edit): Link to "Package Modules" instead of "Defining
Packages".
(Package Modules): Document both GUIX_PACKAGE_PATH and channels.
