inferior: 'gexp->derivation-in-inferior' honors EXP's load path.

2019-01-20T16:57:14Z

Previously the imported modules and extensions of EXP would be missing from the load path of 'guix repl'. * guix/inferior.scm (gexp->derivation-in-inferior)[script]: New variable. [trampoline]: Write (primitive-load #$script) to PIPE. Add #$output. * tests/channels.scm ("channel-instances->manifest")[depends?]: Check for requisites rather than direct references. Adjust callers accordingly.

channels: Don't pull from the same channel more than once.

2019-01-20T16:57:14Z

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.

guix: Add support for channel dependencies.

2018-12-09T12:55:22Z

* guix/channels.scm (): 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.
