12.04 LTS (Precise Pangolin) Weekly Meeting
Upcoming Dates
11/24 - Feature Definition Freeze (aka Planning Freeze)
11/25 - status.ubuntu.com gets reset and tracking work items starts.
12/01 - Alpha 1
Logisitics
Precise Schedule being updated with UDS input - will no longer be draft after Feature Definition Freeze (aka Planning Freeze) (see: https://wiki.ubuntu.com/PrecisePangolin/ReleaseSchedule)
- Any round table order changes requested? - none brought up.
as agreed at UDS, we'll be trying a new meeting format this cycle, with the focus on the IRC session to be on Q&A based on pre-sent team status to ubuntu-release maillist.
UDS session: https://blueprints.launchpad.net/ubuntu/+spec/other-p-release-meeting
overview of new format: https://lists.ubuntu.com/archives/ubuntu-release/2011-November/000471.html
- for this to work, its going to be important that the team statuses should be on ubuntu-release mail list at least 4 hours before the meeting (ideally the night before the meeting, so folks have time to read and digest and think up questions).
Round Table

Status
Overview
We've gotten our blueprints and work items in shape this week (which is evident from the wild ride that is our burndown atm ;). Like in previous releases, the security team gets to development work as time allows and we only commit to completing work items that have an 'Essential' priority.
In that light, this cycle we have done things differently than in the past and moved all of our essential work items into their own essential blueprints. We then created the topic-precise-security-essential blueprint, that depends on our essential blueprints. This gives us and others the ability to more easily see our progress on things we are committed to implementing. (this can of course be seen in http://status.ubuntu.com/ubuntu-precise/canonical-security.html) We have no trend line on the burn down, so I will interpret that as us being below it. 
Bugs of concerrn
http://status.qa.ubuntu.com/reports/kernel-bugs/reports/rls-p-tracking-bugs.html#security
887332: the kernel team is handling this (patch needs to be rewritten and resubmitted upstream)
344878: plan is to make a change to ecryptfs to use pathconf, then to adjust userspace applications like evolution to properly honor pathconf. We will be adjusting ecryptfs and then filing bugs against applications that aren't honoring pathconf
Kernel team update - ogasawara
Extracted from: https://lists.ubuntu.com/archives/ubuntu-release/2011-November/000473.htm
Overall status: https://wiki.ubuntu.com/KernelTeam/ReleaseStatus/Precise
Burn down for Precise Alpha-1: http://people.canonical.com/~platform/workitems/precise/canonical-kernel-team-ubuntu-12.04.html
Burndown for the cycle: http://status.ubuntu.com/ubuntu-precise/group/topic-precise-kernel-tasks.html
What was done engineering wise?
This past week the Ubuntu kernel team has rebased the Precise kernel to upstream v3.2-rc2. Some additional highlights include consolidating the amd64 server and generic flavors, pulling an updated seccomp patch set, building in ahci, and moving ext2 from being built in to enabled as a module. We plan to upload these changes by EOD Fri Nov 18, 2011. This will be the first upload based on a v3.2 kernel.
From my own observations, we appear to be making good progress on our Alpha-1 work items, but it's hard to give a definitive answer without the burn down charts.
We've also been working to get some power consumption measurements for a proposed upstream patch. See the following wiki for more information:
What's about to land that might impact the other teams?
After we've uploaded, we would appreciate any testing feedback particularly from the server team since this will have consolidated the amd64 server flavor into generic.
Additionally, there is a thread on the ubuntu-devel/ubuntu-kernel mailing lists regarding a proposal to drop support for the i386 non-pae kernel flavor for the 12.04 LTS release. Discussions are still ongoing.
Summary of bugs working on by team (reasonably reliable)
As we're haven't yet uploaded a v3.2 based kernel, we're tentatively keeping an eye on the following bugs and will add the rls-p-tracking tag to any that are not be resolved via v3.2.
818830 - [Sandy Bridge] serious power regression from kernel 3.0.0-6 to 3.0.0-7 (rc6 disabled)
855124 - XRANDR operations very slow unless (phantom) HDMI1 disabled
753071 - Include DRM OMAP driver to have proper EDID detection
836250 - Intel Corporation Centrino Ultimate-N 6300 poor networking
Dependencies on other teams, blocking items
None.
Issues?
None.
Foundations team update - cjwatson
Done this week
- CD image builds switched over to new faster build machine. The part of image builds that it does seems about two or three times as fast as before.
- Perl 5.14 transition (97% finished; 14 out of 462 packages still need some work).
- Work on porting python-dbus to Python 3. Compiles and runs but test suite does not fully pass yet.
- Some significant Upstart Cookbook updates, in the area of 'expect fork/daemon'.
- Upstart job logging rework nominally code-complete, but test and documentation still ongoing.
- Scripting work to help us manage our rls-p-tracking tasks.
- Substantial research and planning on the crash database, and some early coding.
- Discussion on lp:~ev/apport/disable-core-removal.
About to land
- New ISO tracker is almost ready to go.
Summary of bugs
We have a lot of items on the rls-p-tracking list, which I think is partly because Steve has been efficient about putting things there. However, almost all are for later milestones. The only alpha-1 bug is:
- Bug 862129: update-manager: "samba postrm depends on packages not
- guaranteed to be configured"
- I'm not entirely clear on the status of this in update-manager; it's
- clearly possible in principle, but will probably require time from Michael. However, I think we can and soon fix the update-inetd part of this quite soon (to make it not rely on Perl modules outside perl-base), and I've pulled that task back to alpha-1 to reflect that.
A related bug which I want to call out as well:
- Bug 891257: doc-base: "doc-base fails to handle perl-base having been
- upgraded but libuuid-perl not"
- This is the same class of problem in a different place. I've sent a
- patch to the corresponding Debian bug report, but it isn't entirely optimal and I'd like to wait for review feedback.
Other non-rls-p-tracking bugs we've been working on:
- Bug 771372: procps: "procps runs too early in the boot process"
- Bug 823366: ifenslave-2.6: "bond_primary is ignored in
- /etc/network/interfaces"
- Bug 829980: upstart: "upstart-udev-bridge eats 100% cpu calling
- dbus_message_iter_append_basic()"
- Bug 876829: ifupdown: "Oneiric's ifupdown breaks ip aliases"
Server team update - Daviey
Tasks Undertaken
- Blueprints, Blueprints, Blueprints
- Further discussion and fact finding on technical implementation of crucial blueprints.

Something Missing?
- Our current focus for tasks to be resolved is listed here: If there is something that you believe that should be targeted, please contact myself or Ursula.
ARM team update - ogra
Linaro update - fabo
Ubuntu One Team - joshuahoover
Desktop Team update - pitti
What was done engineering wise?
- Blueprint drafting and approval almost complete (our target was today); work items are almost complete, and everyone individually as well as the total number of work items are below or at the computed/agreed limit.
- Fixed a couple of bugs in autopkgtest, it's now possible to use for our purposes. Converted the first two packages to DEP-8/autopkgtest for continuous QA integration: upower, apport; more to come. Discussed with Jean-Baptiste how to run these on data center QA machines.
- Worked on getting Unity test harness and tarmac setup ready to go. Also got 51 manual test cases for Unity acceptance criteria written as a draft, covering panel and launcher for now.
- Cleanup of GNOME packages, we were able to coordinate with Debian, do a few updates there, and sync a lot.
- Landed client-side crash signature/duplicate detection in Apport trunk, and discussed integration into Cassandra server with Evan.
What's about to land that might impact the other teams?
- By next Monday we decide about Banshee vs. Rhythmbox. That particularly affects U1. But porting U1 to GTK3 is already unblocked, as we won't go with a GTK2 Banshee in precise.
Dependencies on other teams, blocking items
- Waiting for IS to put Unity tarmac setup into production.
Blueprints

- Burndown and spec completion levels:
Release targetted bugs being worked on/monitored
- under investigation:
851612 [Logging out from a FUS session does not reliably return to VT7]: Race condition, no progress at figuring out the cause yet
- triaged/in progress:
857153 [Needs to get accessibility settings from GSettings]: Problem is clear, but has a workaround
805136 [accounts window doesn't fit on screen and no scrollbar to show hidden fields]: No progress this week.
810721 [at-spi-registryd crashed with SIGSEGV in gconf_client_get_default()]: Got fixed in at-spi2 (which is what we use now mostly); fix might be applicable to at-spi as well.
828623 [gnome control centre does not allow you to disable the laptop screen while leaving an external DisplayPort connected screen working]: Only affects some systems, but great progress on debugging the cause this week.
790240 at-spi needs demotion for precise: No progress this week
- fixed since last report:
Desktop Experience Team Update - dbarth
What was done engineering wise?
- Few bug fixes, quickly stopped because of the absence of test framework and diverging expectations between Unity upstream and Platforms new requirements
- Worked on clarifying the level of tests and defining which types of tests (user-acceptance, system integration, unit test) are required for different types of tasks (bug fixes, feature development)
- Defined 2 tasks forces to unblock the situation and create 2 end-to-end test cases, to serve as as reference for future development work; ETA: next week; this is our ONLY PRIORITY, since the embargo has stalled ALL of the development workflow

What was done engineering wise?
Final version of our blueprint for Precise: https://blueprints.launchpad.net/ubuntu/+spec/community-p-edubuntu
Work items on: http://status.ubuntu.com/ubuntu-precise/group/topic-precise-flavor-edubuntu.html
Jonathan is preparing the re-election of the Edubuntu Council and a plan to change the term to 2 years after this election. Also finalizing the plan for LTS status, to be proposed at the next TB meeting.
What's about to land that might impact the other teams?
LTSP upstream is currently going through a pretty big code cleanup and moving things around. I expect an upload of ldm and ltsp in Precise as soon as things have calmed down. This will impact both Edubuntu and Ubuntu Alternate as both ship LTSP.
Currently LTSP won't boot on Precise due to lack of support for overlayfs.
Summary of bugs working on by team (reasonably reliable)
Haven't started doing much in Edubuntu at this point, most changes are currently done upstream in LTSP and epoptes to bring them to a state where we're comfortable getting them in the archive.
Dependencies on other teams, blocking items
Edubuntu is AFAIk the only flavor that's currently not building. This is caused by fuse/sshfs, blocked on the merge of fuse. This is not critical for us at this point but we'd definitely like that fixed within a week or so or we may need to start moving some work items to alpha-2 instead.
Issues?
I think it's all covered above.

We closely follow the discussion about the PAE kernel. Depending on the hardware affected, it could be big support drop for Lubuntu.
It seems that the future of powerpc will also be discussed later. We have some people interesting in this architecture, and able to test the ISO during this cycle. Depending on this discussion, we may request to add a new powerpc ISO to ISO testing.

stgraber: New ISO tracker - prototype up and available for review at: http://91.189.93.73 .
- the url is the work in progress iso tracker, comments and suggestions are welcome (soon to be feature-equivalent to the current one)
- api works to add builds, api to add results should be there this afternoon
issue: Drupal7 needs to be deployed to support new ISO tracker - skaet opened RT:18823
- cjwatston: I wanted to dig into the dssi-vst/multiarch thing that scott-work raised on -release (and I clarified) in particular I think the answer to this depends very much on whether there's more stuff on its way where we're going to want i386 packages on the amd64 images
- pitti: as for the main Ubuntu images, I'd really like to avoid introducing such a case it would add quite a lot of overhead (you will at least have to install a second glibc etc. onto the images)
cjwatson: main Ubuntu images> agreed
- scott-work: in the short term should we consider removing dssi-vst from the seeds? i can check on the impact of that
- cjwatson: if you're willing to do that, that's a good short-term option IMO; I don't know exactly what features you lose by doing so. perhaps we should have that be downloaded on demand during installation, since it's proprietary? or, well, dependent on proprietary bits anyway, we can discuss by mail or whatever
- pitti: as for the main Ubuntu images, I'd really like to avoid introducing such a case it would add quite a lot of overhead (you will at least have to install a second glibc etc. onto the images)
