2021-03-10channels: Export channel-instance->sexp.Mathieu Othacehe
* guix/channels.scm (channel-instance->sexp): Export it.
2021-02-04channels: Consider the current channel commit as authentic.Ludovic Courtès
Fixes <https://bugs.gnu.org/45895>. When the ~/.cache/guix/authentication is empty, this change allows authentication to start at the current commit, as shown by 'guix describe', instead of starting from the introductory commit, which would take more and more time (there's currently 18K commits per year). * guix/git-authenticate.scm (authenticate-repository): Add #:authentic-commits. [authenticated-commits]: Append it. * guix/channels.scm (authenticate-channel)[authentic-commits]: New variable. Pass it to 'authenticate-repository'.
2021-02-04channels: Record 'guix' channel metadata in (guix config).Ludovic Courtès

(make-config.scm): Add #:channel-metadata and define '%channel-metadata' in the generated file. (guix-derivation): Add #:channel-metadata and pass it to 'compiled-guix'. * guix/channels.scm (build-from-source): Replace 'name', 'source', and 'commit' parameters with 'instance'. Pass #:channel-metadata to BUILD. (build-channel-instance): Adjust accordingly. * build-aux/build-self.scm (build-program): Add #:channel-metadata and pass it to 'guix-derivation'. (build): Add #:channel-metadata and pass it to 'build-program'. * guix/scripts/describe.scm (display-profile-info): Add optional 'channels' parameter. Pass it to 'display-profile-content'. (display-profile-content): Add optional 'channels' parameter and honor it. Iterate on CHANNELS rather than on the manifest entries of PROFILE. (guix-describe): When PROFILE is #f, call 'current-channels' and pass it to 'display-profile-info', unless it returns the empty list.
2021-02-01guix package: Add '--export-channels'.Ludovic Courtès
* guix/channels.scm (sexp->channel): Export. * guix/describe.scm: Use (guix channels). (manifest-entry-provenance): New procedure. * guix/scripts/package.scm (channel=?, export-channels): New procedures. (show-help, %options): Add '--export-channels'. (process-query): Honor it. * build-aux/build-self.scm (build-program)[select?]: Exclude (guix channels) to account for the (guix describe) change above. * doc/guix.texi (Invoking guix package): Document it.

2021-02-01channels: Add the channel name to channel sexps.Ludovic Courtès
* guix/channels.scm (channel-instance->sexp): Add 'name'. (sexp->channel): Extract the name from SEXP, using the optional argument as a fallback.
2021-02-01channels: Factorize 'manifest-entry-channel' and channel serialization.Ludovic Courtès
* guix/channels.scm (sexp->channel, manifest-entry-channel): New procedures. (profile-channels): Replace lambda by 'manifest-entry-channel'. (channel-instance->sexp): New procedure. (channel-instances->manifest)[instance->entry]: Use 'channel-instance->sexp' instead of inline code.
2021-01-31ci: Add missing imports.Ludovic Courtès
This is a followup to 041a9466ea23d6ae811491bcf529bf9487317b48. * guix/ci.scm: Add missing imports. * guix/channels.scm: Remove (guix ci) import.

2020-10-12channels: Address test failure.Ludovic Courtès
Fixes <https://bugs.gnu.org/43940>. Reported by Maxim Cournoyer <maxim.cournoyer@gmail.com>. The "channel-instances->manifest" test would fail since 1d4ab335b22a93e01c2eb1eb3e93fc6534157040: 'quiet-guile' would be passed #f as GUILE, and thus 'package-version' would fail with wrong-type-arg. * guix/channels.scm (whole-package-for-legacy): Pass #:guile to 'whole-package'. * tests/channels.scm ("channel-instances->manifest"): Remove 'test-expect-fail'.
2020-07-25Use 'formatted-message' instead of '&message' where appropriate.Ludovic Courtès
* gnu.scm (%try-use-modules): Use 'formatted-message' instead of '&message'. * gnu/machine/digital-ocean.scm (maybe-raise-unsupported-configuration-error): Likewise. * gnu/machine/ssh.scm (machine-check-file-system-availability): Likewise.

(check-derivation): Ditto.
2020-07-25utils: Move '&fix-hint' to (guix diagnostics).Ludovic Courtès
* guix/utils.scm (&fix-hint): Move to... * guix/diagnostics.scm (&fix-hint): ... here. * gnu.scm: Adjust imports accordingly. * gnu/system/mapped-devices.scm: Likewise. * guix/channels.scm: Likewise. * guix/profiles.scm: Likewise. * guix/scripts/system/reconfigure.scm: Likewise. * guix/ssh.scm: Likewise.
2020-07-11git-authenticate: Factorize 'authenticate-repository'.Ludovic Courtès
* guix/git-authenticate.scm (repository-cache-key) (verify-introductory-commit, authenticate-repository): New procedures. * guix/channels.scm (verify-introductory-commit): Remove. (authenticate-channel): Rewrite in terms of 'authenticate-repository'.
2020-07-01channels: Dependencies listed in '.guix-channel' can have an introduction.Ludovic Courtès
Suggested by Ricardo Wurmus and Simon Tournier. * guix/channels.scm (sexp->channel-introduction): New procedure. (read-channel-metadata): Use it. (profile-channels)[sexp->channel-introduction]: Remove. * tests/channels.scm ("latest-channel-instances, authenticate dependency"): New test. * doc/guix.texi (Channels)[Declaring Channel Dependencies]: Augment example.
2020-07-01channels: Save and interpret 'introduction' field in provenance data.Ludovic Courtès
With this change, profiles created by 'guix pull' & co. include channel introductions as part of the channel metadata of each manifest entry. * guix/channels.scm (channel-instances->manifest)[instance->entry]: Add 'introduction' field when CHANNEL has an introduction. (profile-channels)[sexp->channel-introduction]: New procedure. Use it to initialize the 'introduction' field.
2020-07-01channels: Remove 'signature' from <channel-introduction>.Ludovic Courtès
In the end signing the commit/key pair does not buy us much. Someone publishing a valid but different commit/key pair would effectively be publishing a different channel, which could be a fork (made by a former authorized developer) or simply a mirror. In the latter case, there's nothing to be gained by publishing a different commit/key pair. * guix/channels.scm (<channel-introduction>)[signature]: Remove. (make-channel-introduction): Adjust accordingly.
2020-07-01channels: Make channel introductions public.Ludovic Courtès
* guix/channels.scm (<channel-introduction>): Rename constructor to '%make-channel-introduction'. (make-channel-introduction): New procedure. * tests/channels.scm ("authenticate-channel, wrong first commit signer") ("authenticate-channel, .guix-authorizations"): Use 'make-channel-introduction' without '@@' and without third argument. * doc/guix.texi (Channels)[Channel Authentication, Specifying Channel Authorizations]: New subsections.
2020-07-01channels: Add 'openpgp-fingerprint->bytevector'.Ludovic Courtès
* guix/channels.scm (openpgp-fingerprint->bytevector): New procedure. (openpgp-fingerprint): New macro. (%guix-channel-introduction): Use it.
2020-06-28channels: Error out when the 'guix' channel lacks an introduction.Ludovic Courtès
* guix/channels.scm (latest-channel-instance): Raise an error instead of warning when 'guix is unauthenticated. * tests/channels.scm ("latest-channel-instances, missing introduction for 'guix'"): New test.
2020-06-21channels: 'authenticate-channel' doesn't check relation with intro commit.Ludovic Courtès
Fixes <https://bugs.gnu.org/41908>. Reported by Jan Nieuwenhuizen <janneke@gnu.org>. The relation check imposed an extra restriction that was unnecessary: it's enough to authenticate the set difference between the closure of START-COMMIT and that of END-COMMIT. Any attempt to jump to an unrelated commit would lead to the authentication failure of one commit on the way. * guix/channels.scm (authenticate-channel): Remove extra 'commit-relation' check when (null? commits).
2020-06-17channels: Warn when pulling from a mirror.Ludovic Courtès
* guix/channels.scm (<channel-metadata>)[url]: New field. (read-channel-metadata): Initialize it. (read-channel-metadata-from-source): Likewise. (channel-instance-primary-url): New procedure.

* guix/channels.scm (latest-channel-instance): Add #:authenticate? and honor it. (latest-channel-instances): Likewise. * guix/scripts/pull.scm (%default-options): Add 'authenticate-channels?'. (show-help, %options): Add '--disable-authentication'. (guix-pull): Pass #:authenticate? to 'latest-channel-instances'. * doc/guix.texi (Invoking guix pull): Document it.
2020-06-16channels: Automatically add introduction for the official 'guix' channel.Ludovic Courtès
This is useful when people run "guix time-machine -C channels.scm", where 'channels.scm' misses channel introductions. * guix/channels.scm (%default-channel-url): New variable. (%default-channels): Use it. (ensure-default-introduction): New procedure. (latest-channel-instance): Call it.
2020-06-16channels: Make 'validate-pull' call right after clone/pull.Ludovic Courtès
This should come before patching, authentication, etc. * guix/channels.scm (latest-channel-instance): Add #:validate-pull parameter and honor it. Return a single value: the instance. (ensure-forward-channel-update): Change 'instance' parameter to 'commit' and adjust accordingly. (latest-channel-instances): Adjust to 'latest-channel-instance' changes. * guix/scripts/pull.scm (warn-about-backward-updates): Change 'instance' parameter to 'commit' and adjust accordingly. * tests/channels.scm ("latest-channel-instances #:validate-pull"): Likewise.
2020-06-16channels: 'latest-channel-instance' authenticates Git checkouts.Ludovic Courtès
Fixes <https://bugs.gnu.org/22883>. * guix/channels.scm (<channel>)[introduction]: New field. (<channel-introduction>): New record type. (%guix-channel-introduction): New variable. (%default-channels): Use it. (<channel-metadata>)[keyring-reference]: New field. (%default-keyring-reference): New variable. (read-channel-metadata, read-channel-metadata-from-source): Initialize the 'keyring-reference' field. (commit-short-id, verify-introductory-commit) (authenticate-channel): New procedures. (latest-channel-instance): Call 'authenticate-channel' when CHANNEL has an introduction. * tests/channels.scm (gpg+git-available?, commit-id-string): New procedures. ("authenticate-channel, wrong first commit signer"): ("authenticate-channel, .guix-authorizations"): New tests. * doc/guix.texi (Invoking guix pull): Mention authentication.
2020-05-25pull: Protect against downgrade attacks.Ludovic Courtès
* guix/scripts/pull.scm (%default-options): Add 'validate-pull'. (%options, show-help): Add '--allow-downgrades'. (warn-about-backward-updates): New procedure. (guix-pull): Pass #:current-channels and #:validate-pull to 'latest-channel-instances'. * guix/channels.scm (ensure-forward-channel-update): Add hint for when (channel-commit channel) is true. * doc/guix.texi (Invoking guix pull): Document '--allow-downgrades'.
2020-05-25channels: 'latest-channel-instances' guards against non-forward updates.Ludovic Courtès
* guix/channels.scm (latest-channel-instance): Add #:starting-commit and pass it to 'update-cached-checkout'. Return the commit relation as a second value. (ensure-forward-channel-update): New procedure. (latest-channel-instances): Add #:current-channels and #:validate-pull. [current-commit]: New procedure. Pass #:starting-commit to 'latest-channel-instance'. When the returned relation is true, call VALIDATE-PULL. (latest-channel-derivation): Add #:current-channels and #:validate-pull. Pass them to 'latest-channel-instances*'. * tests/channels.scm ("latest-channel-instances #:validate-pull"): New test.
2020-05-25git: 'update-cached-checkout' returns the commit relation.Ludovic Courtès
* guix/git.scm (update-cached-checkout): Add #:starting-commit parameter. Call 'commit-relation' when #:starting-commit is true. Always return the relation or #f as the third value. (latest-repository-commit): Adjust accordingly. * guix/import/opam.scm (get-opam-repository): Likewise. * tests/channels.scm ("latest-channel-instances includes channel dependencies") ("latest-channel-instances excludes duplicate channel dependencies"): Update mock of 'update-cached-checkout' accordingly.
2020-05-25channels: 'latest-channel-instances' doesn't leak internal state.Ludovic Courtès
* guix/channels.scm (latest-channel-instances): Remove 'previous-channels' argument. Introduce 'loop' and use it.
2020-05-15channels: 'build-from-source' restores '%guile-for-build'.Ludovic Courtès
Not restoring it would cause problems when running: guix time-machine --commit=6298c3ffd9654d3231a6f25390b056483e8f407c or similar because the target Guix would be built with 2.2, and then we'd erroneously go on and attempt build the profile with 2.2. This would fail because profile dependencies such as "guile-gdbm-ffi" now target 3.0. * guix/channels.scm (call-with-guile): New procedure. (with-guile): New macro. (build-from-source): Use it instead of calling 'set-guile-for-build' just once. This ensures that '%guile-for-build' is restored afterwards.
2020-05-15channels: Move quirks and patches to (guix quirks).Ludovic Courtès
* guix/channels.scm (apply-patches): Don't access <patch> record directly; use 'applicable-patch?' and 'apply-patch' instead. (<patch>, syscalls-reexports-local-variables?) (guile-2.2.4, %quirks, %bug-41028-patch, %patches): Move to... * guix/quirks.scm: ... here. New file. (apply-patch, applicable-patch?): New procedures.
2020-05-07channels: Add patch for <https://bugs.gnu.org/41028>.Ludovic Courtès
Without this patch, we couldn't jump from here to commits before 05e783871c2c69b402e088863d46f5be7915ac74 because the 'compute-guix-derivation' script would crash with an unbound-variable error for 'call-with-new-thread'. Fixes <https://bugs.gnu.org/41028>. Reported by Christopher Baines <mail@cbaines.net>. * guix/channels.scm (%bug-41028-patch): New variable. (%patches): Add it.
2020-05-07channels: Add mechanism to patch checkouts of the 'guix channel.Ludovic Courtès
* guix/channels.scm (<patch>): New record type. (apply-patches): New procedure. (latest-channel-instance)[dot-git?]: New procedure. Use 'update-cached-checkout' and 'add-to-store' instead of 'latest-repository-commit'. Call 'apply-patches' when CHANNEL is the 'guix channel. (%patches): New variable. * guix/git.scm (url+commit->name): Make public. * tests/channels.scm ("latest-channel-instances includes channel dependencies") ("latest-channel-instances excludes duplicate channel dependencies"): Mock 'update-cached-checkout' instead of 'latest-repository-commit'. Wrap body in 'with-store' and pass the store to 'latest-channel-instances'.
2020-05-07channels: Add 'latest-channel-instance'.Ludovic Courtès
* guix/channels.scm (latest-channel-instance): New procedure. (latest-channel-instances): Use it.
2020-04-26channels: Use a declarative profile.Ludovic Courtès
* guix/channels.scm (package-cache-file): Use 'profile' instead of 'profile-derivation'.
2020-04-06channels: Call 'build-self.scm' procedure with a trivial build handler.Ludovic Courtès
Previously, "TESTS=installed-os guix build -m etc/system-tests.scm" would repeat the "Computing Guix derivation" phase ~5 times due to the fact that there were several call paths, within a build-accumulator, leading to (package-derivation store guix). * guix/channels.scm (with-trivial-build-handler): New procedure. (build-from-source): Wrap 'build' call in 'with-trivial-build-handler'.
2020-01-09channels: Provide a hint when the 'guix' channel is lacking.Ludovic Courtès
Fixes <https://bugs.gnu.org/39043>. Reported by Jesse Gibbons <jgibbons2357@gmail.com>. * guix/channels.scm (channel-instance-derivations): Raise '&fix-hint' condition in addition to the '&message' condition.
2019-10-27channels: Refer to 'guile-json-3'.Ludovic Courtès
Fixes a regression introduced in 84af1e74029fd4c43636f7d8d3e6f82ddab9ce82. * guix/channels.scm (whole-package-for-legacy): Refer to GUILE-JSON-3, not GUILE-JSON.
2019-10-02channels: Add quirk to build recent 'master' with Guile 2.2.4.Ludovic Courtès
Fixes <https://bugs.gnu.org/37506>. Reported by Marius Bakke <mbakke@fastmail.com>. * guix/channels.scm (syscalls-reexports-local-variables?) (guile-2.2.4, guile-for-source): New procedures. (%quirks): New variable. (build-from-source): Add calls to 'guile-for-source' and 'set-guile-for-build'.
2019-09-23channels: Allow news entries to refer to a tag.Ludovic Courtès
Suggested by Ricardo Wurmus <rekado@elephly.net>. * guix/channels.scm (<channel-news-entry>)[tag]: New field. (sexp->channel-news-entry): Accept either 'commit' or 'tag' in 'entry' forms. (resolve-channel-news-entry-tag): New procedure. (channel-news-for-commit): Move 'with-repository' form one level higher. Call 'resolve-channel-news-entry-tag' on all the news entries. * guix/tests/git.scm (populate-git-repository): Add clause for 'tag'. * tests/channels.scm ("channel-news, one entry"): Create a tag and add an entry with a tag. Check that the tag is resolved and also visible in the <channel-news-entry> record. * doc/guix.texi (Channels): Mention tags in news entries.
2019-09-23channels: Add support for a news file.Ludovic Courtès
* guix/channels.scm (<channel-metadata>)[news-file]: New field. (read-channel-metadata): Set the 'news-file' field. (read-channel-metadata-from-source): Likewise.

2019-08-16channels: Add 'profile-channels'.Ludovic Courtès
* guix/channels.scm (profile-channels): New procedure. * guix/scripts/describe.scm (display-profile-info)[channels]: Define in terms of 'profile-channels'.
2019-07-19channels: Always provide a <channel-metadata> record.Ludovic Courtès
This simplifies the code since one no longer needs to think about whether '.guix-channel' was present. * guix/channels.scm (read-channel-metadata): Always pass a string as the first argument to 'channel-metadata'. (read-channel-metadata-from-source): Always return a <channel-metadata> record. (channel-instance-dependencies): Remove now unneeded 'match'. (standard-module-derivation): Assume DIRECTORY is never #f and contains a leading slash. * tests/channels.scm (channel-metadata-directory) (channel-metadata-dependencies): New procedures. ("channel-instance-metadata returns #f if .guix-channel does not exist"): Remove. ("channel-instance-metadata returns default if .guix-channel does not exist"): New test. (make-instance): Use 'write' instead of 'display' when creating '.guix-channel'. (instance--no-deps): Remove dependencies. (instance--sub-directory): New variable. ("channel-instance-metadata and default dependencies") ("channel-instance-metadata and directory"): New tests. ("latest-channel-instances excludes duplicate channel dependencies"): Expect 'channel-commit' to return a string and adjust accordingly.
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'.
