channels: Always provide a record.

2019-07-19T09:53:47Z

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 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.

channels: Remove unneeded 'version' field of .

2019-07-19T09:53:47Z

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 ()[version]: Remove. (read-channel-metadata, channel-instance-dependencies): Adjust accordingly.

channels: Strictly check the version of '.guix-channel'.

2019-07-19T09:53:47Z

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.

channels: Avoid use of 'derivation-input-path'.

2019-07-15T08:01:05Z

* guix/channels.scm (old-style-guix?): Use 'derivation-name' rather than 'derivation-input-path'.

channels: Add optional directory to channel metadata.

2019-07-13T22:58:09Z

* guix/channels.scm (): 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.

channels: Key cached channel derivations by system.

2019-07-08T11:05:55Z

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'.

channels: Simplify 'channel-instances->manifest'.

2019-07-06T14:17:24Z

* 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'.

deprecation: Use the 'warning' procedure for diagnostics.

2019-06-03T21:18:47Z

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'.

pull: '--url', '--commit', and '--branch' apply to the 'guix' channel.

2019-04-17T11:56:40Z

Suggested by pkill9 . * guix/scripts/pull.scm (channel-list): Apply REF and URL to the 'guix' channel. * doc/guix.texi (Invoking guix pull): Adjust accordingly.

channels: Do not fail when the inferior lacks 'guix repl'.

2019-03-08T11:31:38Z

Fixes . Reported by Martin Flack . 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.
