Fixes <http://bugs.gnu.org/19778>.
Reported by Mark H Weaver <mhw@netris.org>.
* gnu/system/file-systems.scm (%uuid-rx): New variable.
(string->uuid): New procedure.
(uuid): New macro.
* tests/file-systems.scm: New file.
* Makefile.am (SCM_TESTS): Add it.
* doc/guix.texi (File Systems): Give an example of UUID.
* gnu/build/file-systems.scm (read-ext2-superblock*, partition-predicate): New
procedures.
(partition-label-predicate): Rewrite in terms of 'partition-predicate'.
(partition-uuid-predicate, find-partition-by-uuid, uuid->string): New
procedures.
(%network-byte-order): New macro.
(canonicalize-device-spec)[canonical-title]: Check whether SPEC is a string.
[resolve]: New procedure.
Add 'uuid' case and use it.
* gnu/packages/patches/boost-mips-avoid-m32.patch: New file.
* gnu-system.am (dist_patch_DATA): Register patch.
* gnu/packages/boost.scm (boost): Use it.
* guix/scripts/substitute.scm (display-narinfo-data,
process-query, process-substitution): New procedures. Code moved from...
(guix-substitute): ... here. Use them.
* guix/scripts/substitute.scm (or*): New macro.
(%cache-url): Honor "untrusted-substitute-urls".
* guix/tests.scm (%test-substitute-urls): New variable.
(open-connection-for-tests): Use it.
* tests/derivations.scm ("derivation-prerequisites-to-build and substitutes",
"derivation-prerequisites-to-build and substitutes, non-substitutable
build", "derivation-prerequisites-to-build and substitutes, local build"):
Pass it to 'set-build-options'.
* tests/guix-daemon.sh: Likewise.
* tests/store.scm ("substitute query, alternating URLs"): New test.
("substitute query", "substitute", "substitute + build-things with output
path", "substitute, corrupt output hash", "substitute --fallback"): Pass
#:substitute-urls to 'set-build-options'.
This ensures that switching between different substitute servers doesn't lead
to a polluted narinfo cache.
* guix/scripts/substitute.scm (narinfo-cache-file): Add 'cache-url'
parameter. Add the base32 of CACHE-URL as a sub-directory under
%NARINFO-CACHE-DIRECTORY. Update callers.
(cached-narinfo): Likewise. Call 'mkdir-p' on the dirname of the cache
file. Update callers.
(remove-expired-cached-narinfos): Add 'directory' parameter and use it
instead of %NARINFO-CACHE-DIRECTORY.
(narinfo-cache-directories): New procedure.
(maybe-remove-expired-cached-narinfo): Call 'remove-expired-cached-narinfos'
for each item returned by 'narinfo-cache-directories'.
* guix/scripts/substitute.scm (<cache>): Rename to...
(<cache-info>): ... this.
(open-cache): Rename to...
(download-cache-info): ... this. Return a <cache-info> or #f.
(open-cache*): Remove.
(cache-narinfo!): Take a URL instead of a <cache> as the first parameter.
(fetch-narinfos): Likewise. Call 'download-cache-info'. Remove use of
'force'.
(guix-substitute): Replace calls to 'open-cache*' with %CACHE-URL.
* guix/scripts/lint.scm (guix): Remove duplicated lines for using
'srfi-34' and 'srfi-35' modules. These lines were introduced twice by
commits b210b35 and 002c57c.
Co-authored-by: Federico Beffa <beffa@fbengineering.ch>.
* emacs/guix-emacs.el (guix-emacs-find-autoloads-in-directory,
guix-emacs-subdirs): New functions.
(guix-emacs-find-autoloads): Search for autoloads in "guix.d"
subdirectories.
(guix-emacs-load-autoloads): Add subdirectories to 'load-path'.
* emacs/guix-init.el.in: Do not add guix emacs directory to 'load-path'
because it will be done by 'guix-emacs-load-autoloads'. Move
requiring 'guix-emacs' from the top-level to a clause for checking for
'guix-package-enable-at-startup'.
This bug was introduced in commit 85c3127.
Thanks to Christopher Webber for reporting it.
* gnu/syste/linux-initrd.scm (base-initrd): Include (guix build syscalls)
module in derivation.
* gnu/system/vm.scm (expression->derivation-in-linux-vm): Likewise.
