Phillip Lougher (pkl)

  • Working on critical bug #126964 gutsy livefs causes random hangs or modprobe crashes
    • Tracked down cause of hang on Friday 20th July.
      • New liveCD built and released to community for testing.
      • Community confirmed hang solved.
    • Modprobe and other random crashes tracked down to very rare Squashfs file corruption, not solved by above hang bug fix.
      • Available debug information from Squashfs after a number of days analysing bug proved inadequate to locate bug.
      • Spent weekend adding non-invasive debugging support to Squashfs (no logging to dmesg which proved impossible to capture and analyse). Logging information is now cached in memory, and made available as a pseudo file via debugfs.
      • Discovered exceptional circumstances which cause file corruption on Monday 23rd July
      • Located subtle race condition in Squashfs fragment cache code late Wednesday night (4am). Luckily the bug is in code after Feisty and so Feisty and earlier liveCDs do not have this issue.
      • Fixed and tested.
      • New liveCD built and released to community for testing.
  • Analysis of Squashfs logging has shown up some interesting results.

    • Including at start-up, all processes spend a huge amount of time waiting on Squashfs mutexes waiting for data to arrive/decompress off disk. A number of people noticed this via SysRq dumps and assumed deadlocking.

    • Reflecting the large amount of processes waiting for data to arrive via Squashfs, Squashfs spends much of the time with its internal caches 100% committed awaiting data from disk/decompression. This represents a huge bottleneck, and anything to speedup Squashfs operations should show benefits. Some of the improvements to Squashfs I'm currently working on may bring benefits (larger blocks, and metadata prefetch).
    • It is races in the code dealing with full caches which caused the hang and file corruption. This code existed in Gutsy tribe-1 liveCD and apparently were not triggered, which shows the liveCD is now more memory or I/O hungry.
    • Even at start-up with 256 Mbytes of RAM or less, Linux shows signs of memory exhaustion. Squashfs experiences a number of transient failures obtaining page cache blocks, and consequently these operations are retried later.
    • Once the desktop has started-up, there are clear signs of page cache flushing (presumably due to out of memory), as Squashfs is asked to repeatedly re-read blocks. Even at start-up in one log I noticed the /etc/init.d/rc file was re-read twice.

Rick Clark (dendrobates)

  • worked on adding ldap-auth-config tp ldap-auth-client package.
  • python-central training

Till Kamppeter (tkamppeter)

Done:

  • Investigated replacing of gnome-cups-manager by system-config-printer
    • s-c-p is actively maintained upstream
    • s-c-p has a plug-n-print (printer auto-setup feature) provided by the hal-cups-utils package
    • s-c-p has all feature which g-c-m has and even more
    • In s-c-p printers can be shared (or excluded from sharing) individually
    • s-c-p saves printer defaults correctly in /etc/cups/ppd/*.ppd and /etc/cups/printers.conf and not into the user's private ~/.cups/lpoptions
    • s-c-p seems to have less bugs than g-c-m and seems to be better fitted to the current CUPS Only complaint comes from pitti, He says that the icon view of g-c-m is more user friendly.

      --> We should talk about this and make a decision in tomorrow's dev meeting

  • Updated system-config-printer and hal-cups-utils to the current upstream versions. Fixed some Python and CUPS non-root problems. There is still a problem of HAL not running the hal_lpadmin script for queue auto setup when plugging a printer.
  • Reported several bugs in system-config-printer and hal-cups-utils and triaged existing bugs for these packages.
  • Answered bug reports.

Todo:

  • GPL Ghostscript 8.60 will be released on 1st of August. Make an Ubuntu package of it.
