2014-04-14linux-initrd: Mount / as a unionfs when asking for a volatile root.Ludovic Courtès
* guix/build/linux-initrd.scm (make-essential-device-nodes): Make /dev/fuse. (boot-system): Add #:unionfs parameter. Invoke UNIONFS instead of copying files over when VOLATILE-ROOT? is true. * gnu/system/linux-initrd.scm (expression->initrd): Add #:inputs parameter. [files-to-copy]: New procedure. [builder]: Add 'to-copy' parameter; honor it. (qemu-initrd)[linux-modules]: Add 'fuse.ko' when VOLATILE-ROOT?. Pass UNIONFS-FUSE/STATIC as #:inputs; change builder to pass #:unionfs to 'boot-system'.
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. (retrieve-files): Likewise.

(temporary-store-file): ... this. Use 'add-permanent-root' instead of 'add-indirect-root'. (with-temporary-store-file): New macro.

2014-04-08offload: Bail out when failing to register a GC root on the build machine.Ludovic Courtès
* guix/scripts/offload.scm (register-gc-root): Call 'leave' when 'close-pipe' returns non-zero.

Partially fixes <http://bugs.gnu.org/17212>. * guix/utils.scm (errno): Move definition of 'bv' outside of the procedure. Use 'bytevector-s32-native-ref' or 'bytevector-s64-native-ref' instead of 'bytevector-sint-ref'.
2014-04-07Work around behavior of old 'scandir' in Guile 2.0.5.Mark H Weaver
Problem reported by John Darrington <john@darrington.wattle.id.au>. * guix/nar.scm (write-file): Filter out "." and ".." from the result of 'scandir'. Previously we did this by passing a suitable predicate.

Fixes the creation of single-package profiles, reported by Ludovic Courtès. * guix/build/union.scm (union-build): Add new internal procedure 'union-of-directories' that always creates a directory, containing the code previously used only to merge multiple directories. Call it from the multiple-directory case in 'union' and from the top-level 'union-build'.
2014-04-04pki: Introduce 'write-acl', and fix wrong conversion in 'ensure-acl'.Ludovic Courtès
* guix/pki.scm (write-acl): New procedure. (ensure-acl): Use it. Fixes a regression introduced in 39831f1, whereby 'ensure-acl' would yield a wrong-type-arg error. * guix/scripts/archive.scm (authorize-key): Use 'write-acl'.
2014-04-03offload: Prevent the '.drv' and build result from being GC'd.Ludovic Courtès
Before that, there was a small time window during which the GC could wipe the .drv (before 'guix build' has been called), or the build result (before 'retrieve-files' has started.) * guix/scripts/offload.scm (remote-pipe): Add #:quote? parameter and honor it. (%gc-root-file): New variable. (register-gc-root, remove-gc-root): New procedures. (offload): Adjust comment. Run 'guix build' with '-r %GC-ROOT-FILE'.

Follow symlinks for purposes of making decisions about the merge. * tests/union.scm: Remove tests of 'tree-union' and 'delete-duplicate-leaves'.
2014-04-02guix package: 'search-path-environment-variables' traverses module tree once.Ludovic Courtès
* guix/scripts/package.scm (search-path-environment-variables)[manifest-entry->package]: Use 'find-best-packages-by-name' instead of 'find-packages-by-name'. On a profile with 140 packages, this reduces execution time of this procedure from 5.8 seconds to 2.9 seconds (50% improvement.)
2014-04-02guix package: Register non-default profiles as GC roots.Ludovic Courtès
* guix/scripts/package.scm (maybe-register-gc-root): New procedure. * tests/guix-package.sh (profile): Grep the output of "guix gc --list-live" in a couple of places.

* guix/scripts/substitute-binary.scm (regexp-exec): Change formals to (rx str . rest).
2014-04-01substitute-binary: Avoid reloading the ACL repeatedly.Ludovic Courtès
* guix/scripts/substitute-binary.scm (guix-substitute-binary) <--query>: Cache the result of (current-acl); pass it to 'valid-narinfo?' calls. This saves 12% wall-clock time for "guix build emacs -n".
2014-03-31Use 'signature-case' in (guix nar) and 'substitute-binary'.Ludovic Courtès
* guix/nar.scm (restore-file-set)[assert-valid-signature]: Rewrite in terms of 'signature-case'. * guix/scripts/substitute-binary.scm (narinfo-signature->canonical-sexp): Call 'leave' instead of 'raise' when SIGNATURE is invalid.

Mention NARINFO's URI in error messages. Adjust caller. (narinfo-sha256): New procedure. (assert-valid-narinfo): Use it.

* guix/scripts/offload.scm (send-files): Remove 'close-pipe' call from 'guard' handler ('pipe' here referred to Guile's 'pipe' procedure.)
2014-03-26offload: Wait for the processes involved in 'guix archive --missing'.Ludovic Courtès
* guix/scripts/offload.scm (send-files): Keep the second return value of 'filtered-port'. Call 'waitpid' on it.
2014-03-26offload: Allow one transfer in each direction simultaneously.Ludovic Courtès
* guix/scripts/offload.scm (transfer-and-offload): Use 'upload' lock instead of 'bandwidth' around 'send-files' calls, and 'download' lock around 'retrieve-files' call.
2014-03-26offload: Disable SSH-level compression.Ludovic Courtès
* guix/scripts/offload.scm (remote-pipe): Remove '-z' lsh command line argument. This makes transfers almost an order of magnitude slower.
