Activity reports

Colin Watson

  • Removed nasty kernel version hardcoding from armel CD build scripts(the replacement code is nearly as nasty, but at least shouldn't require frequent changes).
  • Ran into udevd crash (#396957) and spent some time helping to track it down.
  • Reviewed/approved specs:
    • foundations-karmic-multiarch-support
  • Sponsorship:
    • libnice #392225.
    • python-pylibacl #391574.
    • scim-bridge #305452.
    • gparted #398099.
    • xscreensaver #398007.
  • Merged: dpkg, grub-installer, partman-auto
  • Archive admin half-day: cleared syncs (plus some minor tool fixes), did a bunch of not-built-from-source removals, adjusted some kernel component overrides, cleared priority-mismatches, cleared binary NEW
  • Feature work:
    • foundations-karmic-server-installer-improvements:
      • Finished and committed LVM configuration rearrangement.
      • Merged mdcfg into partman-md, partly because we've needed to do
        • that for ages anyway and partly because it'll make the RAID configuration rearrangement much easier. Patch sent upstream for review.
      • Started work on RAID configuration rearrangement.
  • Adjusted finish-install for upstart 0.6.
  • Built i486/i586 live CDs out of live filesystems delivered by Adam.
  • Updated my parted swap naming patch; accepted upstream.
  • Reviewed relevant mail thread and added Muharem to the archive administration team. Filed RT ticket for shell access.
  • Caught up on technical-board mail actions.
  • Fixed hdparm #396837 (crash when HDIO_DRIVE_CMD(identify) fails).
  • Fixed partman-auto #287571 (create_primary_partitions sometimes attempts to create last partition larger than free space).
  • TB meeting.

Evan Dandrea

  • Investigated using wubi's tools/pywine to unit test the windows frontend and backend for usb-creator.
  • Reviewed the oem-config and ubiquity merge a number of times,sharing input and patches with mterry.
  • Dug at 397366, but have not found a suitable solution yet.
  • Merged UNR changes to Wubi for NCommander.
  • Undid the merging of bin/usb-creator-{gtk,kde}, cleaning up the code a bit along the way.
  • Released a new Wubi and umenu for 8.04.3.
  • Sorted out some final travel details for Debcamp.
  • Debugged a bug in partman that turned out to be the fault of my desktop running 9.04 rather than karmic.
  • Worked on the slideshow specification. Mostly finished the ubiquity code. Had a discussion with mpt about some aspects of the

design. Tried to start a conversation with Gerry, but he's on holiday until later this month.

  • Followed up with a community member (on ubuntu-installer@) who wanted an option to not wipe a partition on install in ubiquity.

James Westby

Distributed Development

  • Importers down for 4 days due to LP API breaking. Back up now.
  • Cleaned up and improved the documentation somewhat.
  • Investigated some of the failures.

Daily Builds

  • No progress this week.

Kerneloops

  • Worked on the kerneloops changes.
  • Hit a snag that apport may not submit from the same machine that the problem happened on, so need to be a bit more intrusive in to kerneloops than first thought.

Distro Tasks

  • Reviewed some packages on REVU.
  • "Half-day" archive admin duties on Monday.

Other

  • Chasing up confirmation for DebConf/sprint flights (again).

Mike Terry

Ubiquity

  • Finally pushed the oem-config merge to trunk! Thanks to Colin and Evan for spotting and fixing some final issues.
  • Created a branch for translated timezones and filed a merge request. It's very fancy, but there needs to be a bit of discussion about how to sort the unicode lists.
  • Started looking at writing some unit tests

Rsyslog

  • MIR for rsyslog was approved
  • MIR for librelp was not, as there was a possible out-of-bounds error

in librelp that needs to be fixed. I emailed the librelp folks about it.

Muharem Hrnjadovic

My Launchpad past caught up with me :P in the last week I was mostly sorting out package set and archive permission issues that would stand in the way of the archive reorganisation:

Scott James Remnant

  • i486/i586 performance comparisons; the result was that the big performance gain we saw comes from gcc 4.4. There is little changed between -march=i486 and -march=i586 when we *also* force -mtune=generic as we do (generic is in fact tuning for P4-era processors). In fact, the only thing enabled by -march=i586 -mtune=generic over -march=i486 -mtune=generic is the cmpxchg8b instruction, which libc would use if it wasn't explicitly #ifdef'd out. It may be prudent to do the switch anyway in case there are other optimisations later down the line.

Upstart

  • Upstart 0.6.0 was finally released! This is a new stable version based off the D-Busified 0.5 branch I'd been working on for the past couple of years in between management duties.
  • After the release, was still having issues with the "expect fork" and "expect daemon" code [which still uses ptrace()], debugged and applied a patch that seems to fix it well enough until we move to the netlink code.
  • Created a "release" bzr branch of Upstart; this contains common history with both upstart trunk and libnih trunk, merged together in the correct layout - and then has the tarball unpacked over the top.
  • Created an Ubuntu packaging branch from that; I can "bzr pull" to update to the latest release, and I can "bzr merge -c" to cherry-pick from trunk! Smile :-)

  • Some issues with building Upstart on ARM, the test suite triggers a compiler bug and either hangs, runs out of memory or hits an Internal compiler error. I love my test suite.

udev

  • Updated to 145
  • Did some gardening of the bugs list, since I hadn't been focussing on it for a while

util-linux

  • Got the branches all back in sync between Lamont and I
  • Added a commit for Colin's recent upload
  • Updated the Debian and Ubuntu trees to 2.15.1, uploaded to Ubuntu
  • Ported our hwclock udev rules to Debian and made the start rule of the init script conditional on udev not running (agreed during Debian Boot sprint).

Kernel

  • The Upstart test suite strikes again! This time it identified a regression in inotify since it was entirely rewritten upstream to be based on fsnotify
  • Discussed the bug with upstream maintainer, it's being caused by merging duplicate events for a directory based on only the mask - and not checking the filename (ie. multiple CREATE, CHANGE or DELETE events for different files in the same directory are merged into one for the first file)
  • Patches supplied to the kernel team since they just missed rc3

Misc

  • A fair amount of discussion over the gdm vs. getty bug, where both end up sharing the same vt. This is fundamentally caused by getty VTs being hardcoded while X is free to chose the first it thinks is free. I'm still in favour of moving getty to be not hardcoded, so our configuration would be "start N gettys" and they'd get the lowest N numbered VTs after X
