do@gnu.org> 2020-05-28doc: Remove explicit support for mips64el-linux.Efraim Flashner It's been a good run, but no one is maintaining the architecture. So long, and thanks for all the fish. * doc/guix.texi (GNU Distribution): Change text for mips64el-linux to denote it is deprecated. (Daemon Offload Setup): Change occurrences of mips64el-linux to aarch64-linux and adjust local code snippets. (Guix Environment)[cross-compilation]: Change mips64el-linux-gnu to aarch64-linux-gnu. (GNU Build System)(package-cross-derivation]: Same. (G-Expressions)[cross compilation]: Same. (Additional Build Options)[cross-compilation, build logs]: Same. (qemu-binfmt-service-type): Remove mips64el. * doc/contributing.texi (Submitting Patches): Same. * m4/guix.m4: (GUIX_ASSERT_SUPPORTED_SYSTEM): Remove mips64el-linux. 2020-05-28maint: Check whether Guile-Gcrypt is recent enough.Ludovic Courtès Suggested by Danny Milosavljevic <dannym@scratchpost.org> in <https://bugs.gnu.org/41494>. * m4/guix.m4 (GUIX_CHECK_GUILE_GCRYPT): New macro. * configure.ac: Use it. 2020-02-22build: Depend on guile-ssh 0.12.0Lars-Dominik Braun This is a followup to 35f35111678e6622301b414f3d464acb71e106bb. * m4/guix.m4 (GUIX_CHECK_GUILE_SSH): Check for userauth-gssapi! * doc/guix.texi: Document version requirement Signed-off-by: Ludovic Courtès <ludo@gnu.org> 2019-08-17build: 'GUIX_CHECK_GUILE_JSON' really checks for Guile-JSON 3.x.Ludovic Courtès Until now the 'guile' process would always exit with 0, as long as Guile-JSON is installed, whether it's version 1 or version 3. * m4/guix.m4 (GUIX_CHECK_GUILE_JSON): Fix array syntax and remove catch-all 'match' clause. 2019-07-25maint: Switch to Guile-JSON 3.x.Ludovic Courtès Guile-JSON 3.x is incompatible with Guile-JSON 1.x, which we relied on until now: it maps JSON dictionaries to alists (instead of hash tables), and JSON arrays to vectors (instead of lists). This commit is about adjusting all the existing code to this new mapping. * m4/guix.m4 (GUIX_CHECK_GUILE_JSON): New macro. * configure.ac: Use it. * doc/guix.texi (Requirements): Mention the Guile-JSON version. * guix/git-download.scm (git-fetch)[guile-json]: Use GUILE-JSON-3. * guix/import/cpan.scm (string->license): Expect vectors instead of lists.

(alist->package): Pass 'vector->list' on the inputs fields, and default to the empty vector. * guix/scripts/import/json.scm (guix-import-json): Remove call to 'hash-table->alist'. * guix/swh.scm (define-json-reader): Expect pair? or null? instead of hash-table?. [extract-field]: Use 'assoc-ref' instead of 'hash-ref'. (json->branches): Use 'map' instead of 'hash-map->list'. (json->checksums): Likewise. (json->directory-entries, origin-visits): Call 'vector->list' on the result of 'json->scm'. * tests/import-utils.scm ("alist->package with dependencies"): New test. * gnu/installer.scm (build-compiled-file)[builder]: Use GUILE-JSON-3. * gnu/installer.scm (installer-program)[installer-builder]: Likewise. * gnu/installer/locale.scm (iso639->iso639-languages): Use 'assoc-ref' instead of 'hash-ref', and pass vectors through 'vector->list'.
