Adjust 'git-predicate' to use data structures that perform better when used
with git repositories with a large number of files.
Previously when matching either a regular file or directory, 'git-predicate'
would search a list with a length equal to the number of files in the
repository. As a search operation happens for roughly every file in the
repository, this meant that the time taken to use 'git-predicate' to traverse
all the files in a repository was roughly exponential with respect to the
number of files in the repository.
Now, for matching regular files or symlinks, 'git-predicate' uses a vhash
using the inode value as the key. This should perform roughly in constant
amount of time, instead of linear with respect to the number of files in the
repository.
For matching directories, 'git-predicate' now uses a tree structure stored in
association lists. To check if a directory is in the tree, the tree is
traversed from the root. The time complexity of this depends on the shape of
the tree, but it should be an improvement on searching through the list of all
files.
* guix/git-download.scm (files->directory-tree, directory-in-tree?): New
procedures.
(git-predicate): Compute DIRECTORY-TREE. Turn INODES into a vhash.
Adjust body of lambda accordingly.

The '%slots' list could grow indefinitely; in practice though,
guix-daemon is likely to restart 'guix offload' often enough.
* guix/scripts/offload.scm (%slots): Remove.
(choose-build-machine): Don't 'set!' %SLOTS. Return the acquired slot
as a second value.
(process-request): Adjust accordingly. Release the returned slot after
'transfer-and-offload'.
This fixes a memory leak that can be seen by running:
(map (lambda _ (machine-load m)) (iota 1000))
* guix/scripts/offload.scm (machine-load): Add call to 'disconnect!'.
* gnu/packages/patches/perl-dbd-mysql-CVE-2017-10788.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add it.
* gnu/packages/databases.scm (perl-dbd-mysql)[source]: Use it.
* gnu/packages/patches/guile-bytestructures-name-clash.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add it.
* gnu/packages/guile.scm (guile-bytestructures)[source]: Use it.
[arguments]: Unpack the source.
[native-inputs]: New field.
(guile2.0-bytestructures): New variable.
This fixes a regression introduced in the fix for CVE-2017-3142, in BIND
9.9.10-P2, commit ecb232bdfc.
See 'CHANGELOG' in the source distribution for more information.
* gnu/packages/admin.scm (isc-dhcp): Update bundled bind to 9.9.10-P3.
This fixes a regression introduced in the fix for CVE-2017-3142, in BIND
9.11.1-P2, commit faa1369e3c.
See 'CHANGELOG' in the source distribution for more information.
* gnu/packages/dns.scm (isc-bind): Update to 9.11.1-P3.
This is needed to avoid compilation problems caused by the cyclic dependency
between (gnu packages ncurses) and (gnu packages linux).
* gnu/packages/linux.scm (ncurses/gpm): Move to ...
* gnu/packages/ncurses.scm (ncurses/gpm): ... here. Fix misleading
indentation. Add (gnu packages linux) to the module imports.
* gnu/packages/linux.scm (linux-libre)[arguments]: Add to the regex to
find and install the aarch64-linux kernel.
* gnu/system.scm (system-linux-image-file-name): Add entry for aarch64.
