Minutes
- asac, ogra, and persia agreed to meet to discuss getting the non arch specific features of the current kernel backported to the .31 kernel if it was deemed worthwhile.
ericm got a kernel drop from Marvell and is currently working on re-basing it. Initial indications from ericm are that the new re-based kernel could be read this week. ericm pointed out that the Marvell branch is held at http://kernel.ubuntu.com/git?p=marvell/dove-kernel/.git;a=shortlog;h=refs/heads/marvell-dove-2.6.32.2
- There is currently a backlog of team work items for Alpha-2. asac urged the team to check specs, try to complete or push them back to Alpha-3/postpone them where necessary. ogra pointed out that we still have until Monday to close work items and that at least his would be in better shape then.
- NCommander noted that we should have working alternates for Alpha2, although at the moment the dove variant is broken during kernel installation. There was some discussion on whether we should be testing alternates or not due to a lack of man power. The conclusion was that we would produce the images but not officially support them.
asac asked what the status of the debconf-communicate slowness in Casper was. JamieBennett said that there was multiple solutions but one stood out as the best.
- asac asked when all-pairs testing could be done. plars replied that the test pairs are generated and documented on the wiki but detail for them needs to be written on the qa testplan wiki. He went on to explain that the pairs were generated programatically and had to be translated manually into corresponding items.
- ogra indicated that the uboot spec was on target for being completed by the weekend.
JamieBennett raised concern that some MIR's for the 2D launcher were stalled. asac agreed to discuss them after the meeting.
- asac outlined the status of his spec's, thumb work items are review based ones so will be done at the end, chromium is on track after some hard work and suspend-resume testing was mostly moved to Alpha-3. Discussion petered off on to chromiums licensing issues with asac indicating that he was working on it.
- StevenK said that he was planning to break armel images by getting them built as the UNE (Ubuntu Netbook Edition) this week. asac raised concern that we should keep the desktop image until at least Alpha-2 release so we have a working image. StevenK agreed. Discussion continued on what will be the final image for ARM devices, UNE with the 2D launcher was decided to be the main focus.
- asac mentioned that he had gone through the FTBFS (Fail to build package list) and assigned them to either NCommander or dyfet for fixing. NCommander said he had uploaded a fix for ocaml and was thanked for it. Discussion continued on where the focus should be on the FTBFS list, it was concluded that main should be FTB free if possible and universe should be too but focus was on main if a conflict arose.
A more community engaged approach to testing was discussed. As the community generally don't have the hardware to test many of our issues it is quite hard. More blogging and general publicising of what we do is needed. ogra pointed to a post at his blog, http://ograblog.wordpress.com/2009/07/18/juggling-your-arms-in-karmic-and-no-more-excuses/, that indicates some engagement is happening but asac wanted more. ogra, asac and NCommander took the action to blog about ARM work.
Weekly Reports (week before the break for Christmas)
Jamie Bennett (JamieBennett)
This week
Continued on with the Casper investigations. Talked with interested parties to identify the area's of interest. Possible low hanging fruit is disable_guest_account which could be sped up by about 6.5 seconds.
- Tracked down the major cause of slowness for Casper, that of debconf-communicate. Straced, timestamped and looked at this with the conclusion that loading the templates.dat file takes around 4 seconds for every debconf-communicate call. Massive win to get this sped up so identified ways of tackling it. Needs implementing.
Documented possible fixes for Casper slowness here.
- Worked on, along with help from the community, pushing build dependencies for netbook-launcher-efl.
- Little work on the REVU version of netbook-launcher-efl to whip it into shape after the excellent work of mterry.
- Pushed to get Canola packaged.
Now packaged at http://edge.launchpad.net/~canola
- Initial test of Canola proved that it needs some work before it can be the default media player for Ubuntu ARM. Some bugs submitted.
Monthly team report done which can be viewed here.
- Image testing, internal stuff, tending to sick kids, all good fun.
Future
- Come up with a working implementation to fix the debconf-communicate issues.
- Gather monthly information and publish monthly team report.
- Keep pushing and monitoring netbook-launcher-efl dependencies.
- If I get time take a look at the Moblin media player.
- Vacation Tuesday till new year (although I'm sure I'll have some cheeky post-turkey hours to bash some blueprints).
Steve Kowalik
- Propose a patch for Launchpad for a change to germinate, get it merged and landed.
- Upload netbook-meta, pulling from the new netbook.lucid branch. Do so multiple times.
- Merge changes to tasksel, adding netbook, and removed unr and mobile.
- Remove mobile-meta, and discuss with the LOSAs how to remove its seed branch.
- Test my changes to livecd-rootfs, uploading it, and organising installation on the buildds.
- Discover issues that relate to changes with desktop versus une, and fix the seeds. Three times.
- Push out my changes for the rename to the public branch of cdimage.
- Merge the changes into the deployed cdimage code.
- Also fix debian-cd and merge it in too.
- After an hour or so of poking around, discover why my cron.germinate changes caused it to bail and fix two scripts on rookery. Fix component-overrides generation while I was there.
- Thursday archive admin duties.
Tobin Davis
- Continued work on porting LSB tests to arm. Currently focusing on T2C test suites.
Paul Larson
- Was able to begin testing images on imx51 with successful images beginning on 20091213
- Collected additional requested debug data for bug #494787 - firefox crashed with SIGSEGV
- Wrote a script for the bringup testing that uses the bootchart tarball to gather the amount of time it took for boot
- rebuilt dove kernel with patch from bug #494831
- created a new install image with the kernel for bug #494831 to test the fix - fix worked, and I was able to create a working dove image to test with
- made a qemu-arm-static build environment to mess with, see if I can gain any efficiency with it, did some performance comparisons, not impressed with the result
- Tested a new build of Chromium on ARM, still seeing some SIGILL issues, but able to get further
- Started working on install testing blueprint
Alexander Sack
- Vacation.
