16:07 <slangasek> stokachu let me know he can't make the meeting this week - or for all of December actually, but he will be sending a delegate to the meetings for the rest of the month when he can
16:07 <doko> may I conitnue? have to leave early
16:07 <slangasek> and I have nothing to report, other than [VAC] :)
16:07 <slangasek> jodh:
16:08 <jodh> * Upstart
16:08 <jodh> - core-1311-upstart-roadmap: Good progress on cgroup support,
16:08 <jodh> although we can only go so far until the cgroup manager (cgmanager)
16:08 <jodh> spec is completed (bp core-1311-cgroup-manager):
16:08 <jodh> - Updated spec (http://upstart.ubuntu.com/wiki/Cgroup) with further
16:08 <jodh> sub-cgroup details and new initctl command.
16:08 <jodh> - Discussions with straber and hallyn on end-to-end handling of
16:08 <jodh> interactions between Upstart and the cgmanager.
16:08 <jodh> - Wrote parsing code and subset of parser tests for "cgroup" stanza.
16:08 <jodh> - Wrote scafolding code that will eventually call the cgmanager.
16:08 <jodh> - Implemented some of the serialisation+deserialisation code for the
16:08 <jodh> cgroup handling.
16:08 <jodh> - Raised bug 1258098 - in progress (currently working on new tests).
16:08 <ubottu> bug 1258098 in upstart "D-Bus session bus address not serialised" [Medium,New] https://launchpad.net/bugs/1258098
16:08 <jodh> * TODO:
16:08 <jodh> - upstart cgroups:
16:08 <jodh> - Implement D-Bus method and initctl command to notify Upstart of
16:08 <jodh> cgroup managers address.
16:08 <jodh> - Work with stgraber+hallyn to identify best way to avoid upstart
16:08 <jodh> blocking on the cgroup manager.
16:08 <jodh> - Update the spec to add an explanation of how Upstart will
16:09 <jodh> communicate with the cgmanager.
16:09 <jodh> - coerce Upstart devs to help clear the MP backlog :)
16:09 <jodh> ⥟
16:09 <slangasek> doko: go ahead now
16:09 <doko> - compiler work, cross compiler work, bootstrap work, breaking the world with a soname bump
16:10 <doko> - aarch64 now has ssp, but not yet enabled by default
16:10 <doko> (done)
16:10 <cjwatson> Off on Monday with an eye injury.  Mostly better now.
16:10 <cjwatson> Resurrected my auto-cross-builder.
16:10 <cjwatson> Fixed rsyslog regression that broke permission handling in /var/log (bug 1256695, plus bug 484336 as a bonus).

16:10 <cjwatson> - Extensive work on a new snapshot for experimental, intending to get this into trusty before the Christmas break so that we can see how it fares with new ports (ARM, ARM64, PV-GRUB2).  Initial upload almost ready; current roadblock is a grub-install bug.
16:10 <cjwatson> ..
16:11 <stgraber> Hard to know what to report on since we haven't met in quite a while :)
16:11 <stgraber> Anyway, in the past few weeks, I've mostly been doing:
16:11 <stgraber> - cgmanager
16:11 <stgraber> - Helped refine the design and provided prototype implementation
16:11 <stgraber> - Published the cgroup spec for Upstart on the wiki: http://upstart.ubuntu.com/wiki/Cgroup
16:11 <stgraber> - Now helping Serge fight with DBus and libnih limitations
16:11 <stgraber> (it's not impossible that we may have to give up and go back to our own minimal protocol)
16:11 <stgraber> - Setup initial website and mailing-list
16:11 <stgraber> - LXC
16:11 <slangasek> stgraber: any more info you can provide on the status of core-1311-cgroup-manager?  (since jodh mentions things are blocked on the upstart side)
16:11 <stgraber> - Updated our python3 binding with a dozen missing functions/properties
16:11 <stgraber> - Setup auto-generated documentation at http://qa.linuxcontainers.org/master/current/doc/ (thanks to jodh for the doxygen support!)
16:11 <stgraber> - Setup a new mailman server for linuxcontainers.org, planning to migrated all the container mailing-lists on Sunday
16:11 <stgraber> - A ton of code review and dealing with existing bug reports and pull requests
16:11 <stgraber> - Tested unprivileged containers, now waiting for the 3.13 based kernel to actually have this working
16:11 <slangasek> jodh: "notify Upstart of cgroup manager's address" - er, surely the cgroup manager should have a well-known address!?
16:11 <stgraber> - Working on a config rework branch
16:11 <stgraber> - Working on the container auto-start branch
16:11 <stgraber> - Porting lxc-start-ephemeral to the new clone binding
16:11 <stgraber> - Ubuntu touch
16:11 <stgraber> - Wrote a few more tests for the system-image ports branch
16:11 <stgraber> - Setup goldfish as a new device target in trusty
16:11 <stgraber> - Helped debug some problems (that turned out not to really be problems)
16:11 <stgraber> - ISO tracker integration work
16:12 <stgraber> - SRU and New reviews
16:12 <slangasek> doko: what soname bump are you breaking the world with?
16:12 <stgraber> - A bunch of merges (and still slowly working on resolvconf on the side)
16:12 <barry> stgraber: mailman3 right? <wink>
16:12 <stgraber> (DONE)
16:12 <stgraber> slangasek: hallyn is doing most of the implementation which so far unfortunately meant a lot of head banging because of DBus acting rather weirdly with userns
16:12 <stgraber> barry: 12.04, so mailman 2.1
16:12 <barry> stgraber: yeah, just kidding :)
16:12 <doko> slangasek, I think that was pcre3
16:12 <jodh> slangasek: we're not strictly blocked just yet - there are still tests I can write.

16:13 <barry> dmb meeting, vUDS
16:13 <barry> done
16:13 <jodh> slangasek: the point is that upstart needs to be notified when to connect and where to connect. If the latter can default, great, but we'd still need 'initctl connect-to-cgmanager' or similar.
16:13 <cjwatson> stgraber: I just went for the last week, fwiw

16:14 <bdmurray> review and commenting on dpkg already installed and configured bug reports
16:14 <stgraber> slangasek: the specific issues we seem to be having so far is unreliable scm_cred passing over a DBus socket (looks racy for some reason), DBus somehow closing connections when coming from another userns and lack of threading support in our libnih

16:15 <slangasek> jodh: no, not "default" - it should not be configurable at all, the cgroup manager address should be a well-known name, and the dbus interface shouldn't expose an option to change it since we will never need this...

16:15 <slangasek> jodh: as for notification of when to connect, given that the address is always known, can't upstart use inotify here?
16:15 <bdmurray> ⁂ done
16:16 <stgraber> slangasek: can inotify tell you once something bound the socket vs when it was created?
16:17 <doko> slangasek, https://launchpad.net/ubuntu/+source/pcre3/1:8.31-2ubuntu2
16:17 <xnox> slangasek: jodh: i thought upstart would be starting cgroups manager, and thus post-start can emit event to signal upstart that cgroups manager is ready.
16:17 <xnox> or well the fact that cgroups manager started should be enough...
16:17 <stgraber> slangasek: actually, no, inotify won't work because the path will be /sys/fs/cgroup/cgmanager and /sys/fs/cgroup is a tmpfs mounted by cgmanager pre-start so you can't get an inotify watch on that
16:18 <slangasek> stgraber: threading support - why are you using threads? :-(
16:19 <jodh> xnox: that would be another way to do it. However, up to this point, we've adopted the same technique as the notify-* initctl commands.
16:19 <jodh> slangasek: maybe - sounds like we either need more discussion or more spec! :)
16:19 <stgraber> slangasek: I'm not sure, would have to ask Serge. My best guess is that it's to address some of Google's performance concerns but that's just a guess.
16:20 <xnox> jodh: seems like we have too many nofity-* API already. I wonder if it can be a "notify" "var" "value".
16:21 <slangasek> stgraber: I'm pretty sure socket creation == bind, for unix sockets.  but yeah, if the directory heirarchy makes it untenable to do this directly with inotify, I guess a dbus callback may be saner
16:21 <jodh> xnox: yeah, I've actually been vaguely thinking of something like that for a while.
16:21 <slangasek> jodh: discussion/spec> agreed. :)  Where are the discussions on this happening?
16:22 <jodh> slangasek: all over - we have the cgmanager lxc thread (with draft cgmanager spec), the upstart cgroup spec thread, the upstart cgroup spec (courtesy of stgraber), and conversations here and there. Would be kinda useful to have a mini sprint on this I feel.
16:23 * doko has to leave now. will read the backlog
16:23 <jodh> slangasek: I can put another mail out to upstart-devel requesting further feedback on the updated upstart cgroup handling spec for now though.
16:23 <slangasek> jodh: a sprint has the opposite effect of what I'm looking for, which is that the design process is transparent and gets more eyeballs on it
16:23 <slangasek> let's keep discussion on upstart-devel for now, please
16:24 <slangasek> and maybe there should be cc:s to the lxc list, wherever that is?
16:26 <stgraber> I don't think anything that's been discussed in the spec or on upstart-devel currently influences the design on the cgmanager side, so Ccing would just cause extra noise at this point
16:26 <slangasek> ok
16:26 <jodh> slangasek: right. Yes, I'll cc them. I was not necessarily implying a private sprint fwiw :)
16:27 <slangasek> stgraber: is there a spec on the cgmanager side that documents the socket address, so the upstart spec can reference that?
16:27 <stgraber> we're currently having a separate discussion on lxc-devel with Tejun Heo on the inner workings of the daemon itself but that's not very relevant to upstart so I don't think we should Cc that one the other way either
16:27 <slangasek> jodh: public or not, a sprint has fewer people participating than a mailing list :)
16:27 <stgraber> slangasek: it's not set in stone yet due to kernel limitations we may end up with two sockets
16:27 <slangasek> ok
