2014-10-20gnu: Add 'version-prefix' and 'version-major+minor'; use them.Ian Denhardt
The procedure version-prefix truncates a version string to a certain number of components. version-major+minor is a special case of this, which extracts the "major.minor" part of the string. Previously this was handled by an expression common to several packages. * guix/utils.scm (version-prefix, version-major+minor): New procedures * gnu/packages/backup.scm (duplicity): Use version-major+minor. * gnu/packages/cmake.scm (cmake): Likewise. * gnu/packages/gnome.scm (libbonobo, libbonoboui): Likewise. * gnu/packages/gnutls.scm (gnutls): Likewise. * gnu/packages/mail.scm (gmime): Likewise. * gnu/packages/mpd.scm (mpd): Likewise. * gnu/packages/mpi.scm (openmpi): Likewise.

2014-04-14offload: '{send,receive}-files' wait for completion of the transfer.Ludovic Courtès
Fixes situations where the remote 'guix build' is invoked before the .drv has been completely copied, as reported at <https://lists.gnu.org/archive/html/guix-devel/2014-04/msg00174.html>. In some cases 'send-files' would return before the other end is done importing the files, and so the subsequent 'guix build' invocation would just miss the .drv file it refers to. * guix/utils.scm (call-with-decompressed-port): Don't close PORT. (call-with-compressed-output-port): Likewise. * tests/utils.scm ("compressed-output-port + decompressed-port"): Adjust accordingly. * guix/scripts/offload.scm (send-files): Add explicit (close-pipe pipe) call.

2014-03-22utils: 'filtered-port' doesn't leave dangling processes behind.Ludovic Courtès

2014-01-24utils: Add 'fcntl-flock'.Ludovic Courtès

See <https://lists.gnu.org/archive/html/guix-devel/2013-09/msg00137.html> for the rationale. * guix/packages.scm (<origin>)[patches, patch-flags, patch-inputs, patch-guile]: New fields. (%standard-patch-inputs, default-guile, patch-and-repack): New procedures. (package-source-derivation): When 'patches' is non-empty, call 'patch-and-repack'. * guix/utils.scm (file-sans-extension): New procedure.
2013-08-23utils: Add `guile-version>?', and use it.Ludovic Courtès
This fixes Guile version comparisons when (version) has a vendor-specific suffix. Reported by Andreas Enge <andreas@enge.fr>. * guix/utils.scm (guile-version>?): New procedure. * tests/utils.scm ("guile-version>? 1.8", "guile-version>? 10.5"): New tests. * guix/scripts/substitute-binary.scm (fetch, progress-report-port): Use `guile-version>?' instead of `version>?'. * guix/http-client.scm (when-guile<=2.0.5, http-fetch): Likewise.
2013-07-01Move `sha256' to (guix hash).Ludovic Courtès
* guix/utils.scm (sha256): Move to... * guix/hash.scm: ... here. New file. * Makefile.am (MODULES): Add it. * guix/derivations.scm, guix/scripts/download.scm, guix/scripts/hash.scm, guix/scripts/refresh.scm, tests/base32.scm, tests/derivations.scm, tests/store.scm: Use (guix hash).

2013-05-15substitute-binary: Pass `filtered-port' an unbuffered port.Ludovic Courtès
This fixes a bug whereby `read-response' would read more than just the response, with the extra data going into the port's buffer; the "bzip2 -dc" process spawned by `filtered-port' would not see the those buffered data, which are definitely lost, and would bail out with "bzip2: (stdin) is not a bzip2 file." * guix/utils.scm (filtered-port): Document that INPUT must be unbuffered. * guix/web.scm (http-fetch): Add `buffered?' parameter. Call `open-socket-for-uri' explicitly, and call `setvbuf' when BUFFERED? is false. Pass the port to `http-get'. Close it upon 301/302. * guix/scripts/substitute-binary.scm (fetch): Add `buffered?' parameter. Pass it to `http-fetch'; honor it for `file' URIs. (guix-substitute-binary): Call `fetch' with #:buffered? #f for port RAW. * tests/utils.scm ("filtered-port, file"): Open FILE as unbuffered.
2013-05-12Move record utilities to (guix records).Ludovic Courtès
* guix/utils.scm (define-record-type*): Move to... * guix/records.scm: ... here. New file. * guix/build-system.scm, guix/packages.scm: Use it. * guix/gnu-maintenance.scm: Likewise. (official-gnu-packages)[alist->record]: Remove. * guix/scripts/substitute-binary.scm: Likewise. (alist->record, object->fields): Remove. * tests/utils.scm ("define-record-type*", "define-record-type* with letrec* behavior", "define-record-type* & inherit", "define-record-type* & inherit & letrec* behavior", "define-record-type* & thunked", "define-record-type* & thunked & default", "define-record-type* & thunked & inherited"): Move to... * tests/records.scm: ... here. New file.
