[arch-dev-public] new pkg for extra: LXDM
by Andreas Radke 10 Oct '10

10 Oct '10

LXDM had a nice stable release 0.3.0 a few weeks ago and is ready to use. It's the best light weight alternative we have next to gdm/kdm and slim/xdm. I know about Jürgens ask for help on lxde packages but I'd like to maintain lxdm in extra independent from lxde as an option for Xfce users. Any objections? -Andy

[arch-dev-public] tar based sync backend implemented!
by Allan McRae 10 Oct '10

10 Oct '10

Hi, I have implemented the reading directly from the db tarball for sync databases. See the patchset on by "backend" branch (http://projects.archlinux.org/users/allan/pacman.git/log/?h=backend). Some of the changes are quite big (e.g. 9 files changed, 2184 insertions, 1571 deletions), but that is mainly moving and duplicating code in the process of splitting the handling of local and sync dbs. There is still _a lot_ of clean-up to be done in the code, but it is fully functional. This breaks pactests... lots of pactests... but that is expected as the pactest suite does not understand a tar based sync db. I would like help fixing that as I get lost in the pactest code. Anyway, here is the timing for some operations. First time is with dropped caches, the second running it again with the db cached. pacman -Syy (download time ~15-20sec) old: 1m25.197s, 0m22.445s new: 0m19.391s, 0m22.084s (download speed variation...) pacman -Sl extra old: 0m6.973s, 0m0.193s new: 0m3.974s, 0m0.390s pacman -Ss pacman old: 0m11.521s, 0m0.395s new: 0m4.171s, 0m0.477s pacman -Si pacman old: 0m6.067s, 0m0.101s new: 0m1.929s, 0m0.437s echo "n" | pacman -Su (five packages to update) old: 0m17.823s, 0m0.306s new: 0m10.577s, 0m0.489s So the tar backend gets some quite significant speed gains in the uncached case, and has marginal losses when the db is cached. Note that the entire sync db is read and parsed no matter the (sync) operation. That explains the difference in the cases with the db cached. This could be adjusted to read the package list (pkgname, pkgver-pkgrel) first and read the desc/depends files for the entire db or a single package as needed but that is probably distant future stuff...

[arch-dev-public] [signoff] sqlite3 - 3.7.3-1
by Andreas Radke 08 Oct '10

08 Oct '10

Upstream update. Please give signoffs. -Andy SQLite Release 3.7.3 On 2010 October 08 (3.7.3) Changes associated with this release include the following: * Added the sqlite3_create_function_v2() interface that includes a destructor callback. * Added support for custom r-tree queries using application-supplied callback routines to define the boundary of the query region. * The default page cache strives more diligently to avoid using memory beyond what is allocated to it by SQLITE_CONFIG_PAGECACHE. Or if using page cache is allocating from the heap, it strives to avoid going over the sqlite3_soft_heap_limit64(), even if SQLITE_ENABLE_MEMORY_MANAGEMENT is not set. * Added the sqlite3_soft_heap_limit64() interface as a replacement for sqlite3_soft_heap_limit(). * The ANALYZE command now gathers statistics on tables even if they have no indices. * Tweaks to the query planner to help it do a better job of finding the most efficient query plan for each query. * Enhanced the internal text-to-numeric conversion routines so that they work with UTF8 or UTF16, thereby avoiding some UTF16-to-UTF8 text conversions. * Fix a problem that was causing excess memory usage with large WAL transactions in win32 systems. * The interface between the VDBE and B-Tree layer is enhanced such that the VDBE provides hints to the B-Tree layer letting the B-Tree layer know when it is safe to use hashing instead of B-Trees for transient tables. * Miscellaneous documentation enhancements.

[arch-dev-public] [signoff] glibc-2.12.1-2
by Allan McRae 08 Oct '10

08 Oct '10

A few maintenance changes: - pull latest upstream snapshot from 2.12 branch (only a couple of minor bugfixes) - Fedora patch to not optimize so much during linking for those "i686" machines that do not handle it. Real fix will be in binutils-2.21 - Gentoo patch to fix static linking issues. Not quite accepted upstream yet but at least one of the main contributors has pulled it to his branch. - make-3.82 fix - ldd on x86_64 should work nicely with multilib packages (and not affect anyone not using them) Signoff both, Allan

Mirror status and customized mirror lists The website now provides a [mirror status page](/mirrors/status/) that regularly polls all known mirrors and gathers statistics like delay, check duration, and availability. Please consult the page for more details on what is collected and how it works. In addition, you can now [update your mirrorlist](/mirrorlist/) and choose to have it automatically sorted using the up-to-date mirror status information.
