15:04 <barry> done
15:04 <slangasek> * short week due to Memorial Day in the US
15:04 <slangasek> * slow week, still recovering from plane plague
15:04 <slangasek> * reviews finished
15:04 <slangasek> * new skype uploaded to partner
15:04 <slangasek> * DebConf travel plans all sorted out
15:04 <slangasek> * LPC travel plans to be finalized this week
15:04 <slangasek> * fixed sysvinit regression (invoke-rc.d) cascading from a fix to debhelper to make sure we actually call invoke-rc.d for packages that ship an upstart job but not an initscript; this unfortunately broke builds for a day
15:05 <slangasek> (done)
15:05 <ev> - Worked with Katherine and Neil to get the NDA for https://errors.ubuntu.com
15:05 <ev> written and published:
15:05 <ev> https://forms.canonical.com/reports/
15:05 <ev> - Drafted an announcement of the NDA to ubuntu-devel@.u.c. Waiting on some peer
15:05 <ev> review from Matthew.
15:05 <ev> - Created a package that purposefully fails in its postinst, creating an apport
15:05 <ev> package installation failure report. Modified apport-test-crashes to install
15:05 <ev> this in a fakechroot and include the apport report in its output. I just need
15:05 <ev> to add this to the integration test now.
15:05 <ev> - Simplified the design of our Tarmac machinery. It was taking too long to
15:05 <ev> cover all the corner cases in tearing down the world with each deployment
15:05 <ev> attempt. Instead, we start with a deployed set of charms and the Tarmac
15:05 <ev> instance uses the upgrade-charm functionality (that we created for use in
15:05 <ev> stagingstack) to deploy the code from the MP.
15:05 <ev> - Finished the above and deployed it. It works \o/:
15:05 <ev> http://bazaar.launchpad.net/~daisy-pluckers/daisy/trunk/revision/349
15:06 <ev> - Investigating the creation of a "What's unusual about this error?" section to
15:06 <ev> the problem page:
15:06 <ev> https://wiki.ubuntu.com/ErrorTracker#A.2BIBw-What.2BIBk-s_unusual_about_this_error.2BIB0-
15:06 <ev> Started work on surfacing common dependencies between the instances as a
15:06 <ev> first pass. This will help us identify cases where the bug exists in the
15:06 <ev> library, not the binary its surfacing in. Discussions with Matthew on what
15:06 <ev> defines the "rate for matching machines" and whether this is better than a
15:06 <ev> simple percentage of the total instances.
15:06 <ev> Blocked:
15:06 <ev> - The webops team has been sprinting in the weeks since UDS as training for the
15:06 <ev> move to squads. This has meant that all non-critical tickets are on hold.
15:06 <ev> - We're also stuck by the Cassandra cluster not having enough free disk space
15:06 <ev> for compaction. Tickets that create new data, such as back-population jobs,
15:06 <ev> are on hold until this is resolved:
15:06 <ev> https://rt.admin.canonical.com/Ticket/Display.html?id=61432
15:06 <ev> - Due to the way I constructed our oops.canonical.com support, we're blocked on
15:06 <ev> further deployments of lp:errors until the RT lands:
15:06 <ev> https://rt.admin.canonical.com/Ticket/Display.html?id=61393
15:06 <ev> Misc:
15:06 <ev> - I attended a talk last night by Russel Winder on how Go and D stack up
15:06 <ev> against Python:
15:06 <ev> http://skillsmatter.com/podcast/nosql/are-go-and-d-threats-to-python/mh-7418
15:06 <ev> I don't think it's worth the language wars that would follow a trip report,
15:06 <ev> nor was there a lot of meat in there for the canonical-tech crowd, but I was
15:06 <ev> surprised to see that Go's error handling is enforced by policy, not code.
15:06 <ev> Unlike exception-based languages, you end up with the whole thing blowing up
15:06 <ev> some distance from where the error actually occurred. Julian does a better
15:06 <ev> job of explaining it:
15:06 <ev> http://bigjools.wordpress.com/2013/04/24/error-handling-in-go/
15:06 <ev> That said, it seems like an interesting enough language for server workloads,
15:06 <ev> assuming it gets a some mature batteries.

15:07 <stgraber> Blueprint-related work:
15:07 <stgraber> - Image based updates (BLUEPRINT: foundations-1305-image-based-updates)
15:07 <stgraber> - Waiting on review of the GPG implementation plan, need to get the keys generated and signed after that.
15:07 <stgraber> - Waiting for IS to setup the image based update server.
15:07 <stgraber> - Fixed a couple of bugs in the image diffing tool, adding a proper test suite now.
15:07 <stgraber> - Discussion with lifeless and barry.
15:07 <stgraber> Other work:
15:07 <stgraber> - release/cdimage
15:07 <stgraber> - Wrote a new rebuild-requests tool to query any pending rebuild from the ISO tracker.
15:07 <stgraber> - Started integrating this with the actual build process so we can cron that thing.
15:08 <stgraber> - Smaller code change to the tracker to automatically mark a rebuild request as done when a new version is pushed (manually or through the API).
15:08 <stgraber> - LXC
15:08 <stgraber> - Pushed C implementation of get_ips in LXC API, dropped the python implementation and update the bindings
15:08 <stgraber> - Fixed LXC in saucy to install properly on a device with network bridges available in the kernel (touch devices).
15:08 <stgraber> - Answered some #ubuntu-phone question for the container flip, things appear to be going well
15:08 <stgraber> - Answered some questions from the QA/desktop team on using LXC for their desktop tests
15:08 <stgraber> - Drafted the implementation of container autostart upstream (to replace the Ubuntu-specific implementation)
15:08 <stgraber> - Updated the build/testing server to build on saucy and add armhf builds to the mix
15:08 <stgraber> - Various discussions and code reviews for major upstream changes needed for LXC 1.0
15:08 <stgraber> - Merged gnupg2, installation-report, openvpn, ifenslave-2.6 and nfs-utils (waiting on testing from slangasek for that last one)
15:08 <stgraber> - SRUed isc-dhcp to precise and lucid to allow both to be used as containers on saucy (required backporting the UDP checksum offloading patch)
15:08 <stgraber> 
15:08 <stgraber> TODO:
15:08 <stgraber> - Finish self-rebuilds feature implementation on nusakan
15:08 <stgraber> - Implement some of the remaining bits for the image based update server tools
15:08 <slangasek> stgraber: ack, will test nfs-utils today
15:08 <stgraber> - Process some pending merges (ifupdown and resolvconf)
15:08 <stgraber> (DONE)
15:08 <stgraber> slangasek: thanks
15:09 <slangasek> testing these things would be easier if someone could explain to me why my kernel is holding 1.5GB of memory for disk caches that it will never free
15:09 <slangasek> well.  a *lot* of things would be easier if that were the case
15:10 <slangasek> ev: "tickets that create new data" - does that block anything for phased updates? bdmurray?
15:10 <bdmurray> slangasek: yes
15:10 <slangasek> blast - ok.
15:10 <bdmurray> although it may not be critical as it is the count of systems that have experienced a crash
15:11 <slangasek> well, ticket #61432 already has "priority 20000", that's probably good enough :P
15:11 <bdmurray> and actually its backfilling data so not important for packages entering -updates
15:11 <ev> bdmurray: you might have some luck if you raise your ticket with the vanguard, as he was correcting my statement that we're blocked by the sprint :)
15:12 <slangasek> oh, and stokachu is out this morning, and cjwatson is off today
15:12 <slangasek> so, bdmurray:
15:12 <bdmurray> submitted RT regarding backfill of bucketsystems
15:12 <bdmurray> further work on phased-updater code
15:12 <bdmurray> submitted merge proposal regarding sru-review
15:12 <bdmurray> review of slangasek's change to sru-review
15:12 <bdmurray> review of pending SRUs for errors bucket information
15:12 <bdmurray> wrote blog post regarding SRU verification

15:14 <slangasek> stgraber: image-based update server> I did update the ticket with deadline+priority, but based on what ev's said I guess this ticket is not going to move for a few weeks.  Is that holding anything up for you?
15:14 <slangasek> stgraber: and thanks for getting the ifupdown merge; I meant to ask you if that was safe for me to do or if you wanted it held off
15:14 <barry> bdmurray, doko think it's time to sru lp: #1058884 ?

15:15 <doko> barry, I think it doesn't do any harm
15:15 <doko> another question if it will help ...
15:15 <slangasek> from the profile of that bug report, I suspect it will
15:16 <slangasek> so, +1 from me for SRUing
15:16 <bdmurray> barry: sounds good to me
15:16 <slangasek> are there any python SRUs currently stuck in the queue?  Hmm, I would check this but pending-sru report is broken at the moment - doh
15:16 <barry> yep, good, i'll get that started.  doko did i see that you got the same patch into debian?
15:16 <bdmurray> I believe there are / were
15:16 <doko> yes, there are still some 2.7 ones
15:16 <doko> or 3.2?
15:17 <stgraber> slangasek: ifupdown is always a pain to merge but I know where the problems tend to be so figure it'd be a lot faster for me to do it
15:17 <stgraber> slangasek: so we need the server and the GPG keys online and ready by end of June if we want to respect our deadlines
15:17 <stgraber> slangasek: it's not preventing developement of the other bits as we're using phablet.stgraber.org currently which has a valid SSL certificate and can be used with barry's code
15:17 <slangasek> stgraber: ok.  I'll make sure to revisit this with IS in the sync call next week, then.
15:18 <slangasek> doko: your turn
15:18 <barry> stgraber: did you fill out the /gpg tree?
15:18 <doko> - android cross toolchain (wanted to upload today, let's see if this works out)

15:19 <stgraber> barry: was actually hoping to hear back from you on the changes I did on the wiki. If everything looks good to you, I'll go ahead and do the changes to phablet.stgraber.org
15:19 <xnox> * boost1.53 is finished (less than 17 ftbfs packages left to be
15:19 <xnox> resolved in Debian, libreoffice update is being prepared by bjorn)
15:19 <xnox> * merged updated fuse, fuse-utils package renamed to fuse (and
15:19 <xnox> transition reverse-deps to the new name)
15:19 <xnox> * pushed some of ubuntu's d-i delta back to debian, and merged back to
15:19 <xnox> ubuntu.
15:19 <xnox> * merged and uploaded ubuntu1 plugin for ubiquity, but disabled by
15:19 <xnox> default. Can be activated with --sso flag. Prepared instructions for
15:19 <xnox> design team review of the changes.
15:19 <xnox> * Reviewed changes to ubuntu-geonames service from Liam Young, he is
15:19 <xnox> working on charming geonames to work on prod-stack (from IS sprint)
15:19 <xnox> * Still have ~40 TIL merges left as per MoM, which I hope to resolve
15:19 <xnox> (ideally by syncing ;-))
15:19 <xnox> * In-progress adding logind support to ubiquity, I correctly receive
15:19 <xnox> seat&session, yet ubiquity doesn't start-up under logind yet.
15:19 <barry> stgraber: ack.  i'll get back to you on that later today
15:19 <xnox> * Booked travel for DebConf13
15:19 <xnox> done.
15:19 <stgraber> barry: IIRc changes are mostly format of the keyrings, blacklist keyring, format change of channels.json and some changes on what's using detached signatures vs in-line signatures
15:21 <slangasek> xnox: "doesn't start up under logind" - hmm, what does that mean?
15:23 <xnox> slangasek: still investigating, ubiquity-dm terminates and doesn't give much useful output. will crank up dbus logging to see what is preventing ubiquity from opening a logind session.
15:24 <slangasek> xnox: ok
15:24 <slangasek> any other questions over the above?
15:24 <xnox> slangasek: now that we have upstart-usersessions, I wonder if ubiquity should simply be a user-job which simply starts up before unity & blocks it.
15:25 <slangasek> xnox: mmm, no idea - maybe stgraber has some thoughts on that
15:25 <stgraber> xnox: we don't have upstart usersesssion for !ubuntu
15:26 <xnox> (if that is possible, it's more of a wondering). Also since there is no pam session initiated, there is also no XDG_RUNTIME and etc. variables.
15:26 <xnox> (XDG_RUNTIME_DIR that is)
15:26 <stgraber> if we had, we indeed could ship a "start on starting xsession-init and dbus" job which would start ubiquity
15:27 <slangasek> you could theoretically split the binary package for user-session activation vs. system activation
15:27 <slangasek> though that could make for some unpleasant bit rot on the system activation case
15:28 <stgraber> indeed. I'm not sure what's the benefit though if we end up having to maintain the two (sure, the flavours would be responsible for ubiquity-dm, but in the end we'll still be the ones reviewing those and fixing quite a few of the bugs I expect)
15:29 <slangasek> right, except perhaps in encouraging the flavors to move to upstart user sessions sooner?
15:29 <slangasek> but anyway - probably a conversation for another time and place
15:29 <slangasek> [TOPIC] Bugs
15:29 <slangasek> bdmurray: any bugs you've not gotten answers on already?
15:30 <bdmurray> oh, bug 1094218 received an interesting comment
15:30 <stgraber> I can probably quickly look into what would be needed to get kde, lxde and xfce to use user sessions. I don't think it's much more than a single upstart job that starts the right *-session binary
15:30 <ubottu> bug 1094218 in lsb (Ubuntu) "lsb_release crashed with IOError in getstatusoutput(): [Errno 10] No child processes (called by teamviewerd)" [Medium,Confirmed] https://launchpad.net/bugs/1094218
15:31 <barry> bdmurray: i still have a browser tab open on that one.  i haven't looked closely, but a cursory look was a bit mysterious
15:32 <bdmurray> barry: a look at the last comment?
15:32 <slangasek> it's a bit speculative
15:32 <slangasek> "there may be a SIGCHLD handling bug in python" - sure, there may
15:33 <slangasek> but the pipe code has been there a while, how has nobody hit this before?
15:33 <slangasek> barry, doko: anyway, it might be worth one of you having a look at os.popen() vs. http://bugs.python.org/issue9127
15:33 <barry> yeah, if sys.stderr is closed or otherwise unavailable, that would probably cause the crash.
15:33 <slangasek> ah
15:34 <slangasek> sys.stderr being closed seems quite plausible here
15:35 <slangasek> and I guess reproducing that requires actually closing stderr, not just redirecting to /dev/null :)
15:35 <slangasek> (not sure of a good way to test that from shell)
15:35 <slangasek> anyway
15:35 <slangasek> barry: will you follow up?
15:37 <barry> slangasek: yeppers
15:37 <slangasek> great, thanks
15:37 <slangasek> bdmurray: anything else?
15:38 <slangasek> ... assuming not :)
15:38 <bdmurray> slangasek: nope
15:38 <slangasek> [TOPIC] AOB
15:39 <slangasek> bdmurray: ok, thanks :)
15:39 <slangasek> anything else new and exciting?
15:40 <stgraber> did I ever mention how much I hate ubuntu-release-upgrader? It's now my 5th try at building a source package. I "think" I've got all the needed packages installed on my system now...
15:40 <slangasek> stgraber: are you using bzr bd?
15:40 <stgraber> yep
15:40 <barry> stgraber: i feel your pain
15:40 <slangasek> hmm, this package is missing the bzr-builddeb integration hook!
15:41 <slangasek> did someone forget to add that when splitting from update-manager?
15:41 <stgraber> it just annoys me that this package has more dependencies to build a source package than it has to actually build the binaries :)
15:41 <slangasek> yeah
15:41 <stgraber> slangasek: it has the hook, pre-build.sh is being called by bzr bd
15:41 <slangasek> stgraber: the pre-build.sh should prompt you for all the build-deps in one go, AFAICS
15:41 <slangasek> and if it's not doing that, update the dpkg-checkbuilddeps line :)
15:41 <bdmurray> I think infinity had mentioned one was missing at the sprint
15:42 <stgraber> slangasek: it does for what's needed by the testsuite, then the source package fails to build 5min later because you also need all the build-deps apparently
15:42 <bdmurray> or he fixed one
15:42 <slangasek> looks like he did, yes
15:43 <slangasek> stgraber: oh; I was assuming you'd done 'sudo mk-build-deps -i -r' or equivalent before calling bzr bd, too :)
15:43 <slangasek> anywayz
15:43 <slangasek> stgraber: thanks for fixing invoke-rc.d :)
15:43 <stgraber> slangasek: most if not all packages I maintain don't depend on half the world just to build a source package ;)
15:44 <stgraber> anyway, I apparently just got a source package, let's see if I can build that thing and test it somehow
15:44 <slangasek> heh
