apwhenrix, yo ... did you do the CVE work for CVE-2013-3076 ?  11:14
apwthe matrix says that lucid is missing and wondering if it is in the pipeline, or got lost in application11:15
apwi have deleted all the emails of course so i cannot check11:15
apwoh god it is quiet ... help11:55
* ppisati -> out for a late lunch12:13
* cking takes an even later late lunch12:53
mdeslaurslightly interesting: http://jwboyer.livejournal.com/47022.html13:08
apwmdeslaur, slightly interesting indeed, mostly cause it says we are in sane line mostly13:51
apwmdeslaur, thanks for the pointer13:51

apwcking, do you have an up to date raring xen install?  i am getting failures creating new domains13:57
apwUnable to complete install: 'POST operation failed: xend_post: error from xen daemon: (xend.err "Error creating domain: kernel '/usr/lib/xen-default/boot/hvmloader' not found")'13:58
ckingapw, I can find my Xen install and give it a go13:58
apwcking, do you even have one of those ?  if so what package is it in :)13:58
apwi was just trying to spin up some saucys13:58
* cking can't get it to boot - gimme a mo while I find a spare monitro14:00
apwcking, that is so just the pain i went through14:02
* cking starts to update it14:05
apwcan you ask dpks where that comes from, in case it goes away14:06
apwdpkg -S /usr/lib/xen-default/boot/hvmloader14:06
ckingjust a sec, it's still booting 14:08
apwrtg, yo ... i have pushed a manta-apw branch to saucy so you can see how i think this should be fixed14:40
apwrtg, if you concur then i'll do the others14:41
apwsee my email reply for reasoning14:41
rtgapw, just sent email on k-team list14:41
apwrtg, see it now, great i'll get that sorted out.14:43
apwrtg, do we have an hwe branch for saucy yet ?  as i need to test that one also if so.14:44
apwhenrix, about ?14:44
rtgapw, if you get those changes into master-next, then I can take care of syncing manta14:44
apwrtg, works for me, i'll let you know14:44
rtgapw, I'll work on learning mutt in the meantime. I'm fed up with thunderbird.14:45
zequencertg: If you don't mind proprietary, try the opera builtin mail client. It's the best gui client I've ever used for high mail traffic14:50
zequenceThat said, I'm in the process of transitioning to mutt myself, and using imapfilter to sort the mail14:51
apwmdeslaur, bizarrly you seem to have worked on an old bug against virt-manager wherein it triggers this error "Error creating domain: kernel '/usr/lib/xen-default/boot/hvmloader' not found" ... seems I have this right now in raring14:53
mdeslaurapw: hrm, I probably just added a fix that someone gave me...I've never personally used virt-manager with xen14:54
mdeslaurapw: does that file exist?14:54
apwmdeslaur, in fact you closed it for lack of feedback from the user14:55
mdeslauroh, hehe14:55
apwmdeslaur, nope, in keeping with the bug, i have a xen-4.2 version14:55
apwbut nothing xen-default14:55
* apw pokes libvirt to see if this is in it14:56
mdeslaurhrm, looks like that changed at some point14:56
apwwell cirtainly libvirt has a heap of xen-default paths in it14:57
apwoh it has a patch to fix this, but ... not sure it is applied14:57
mdeslaurdoes the xen package actually create a xen-default symlink to xen-4.2?14:58
apwi don't think it does, and i think libvirt in saucy is patched to remove those paths too14:58
mdeslauroh, yeah, I see that now14:58
apwi see this was well tested in raring before release, sigh14:59
mdeslaurbut then, something needs to put hvmloader in the path14:59
mdeslaurapw: I'd poke hallyn for libvirt14:59
apwmdeslaur, will do indeed, i think it is meant to be fixed in what i am running15:00
apwso i am going to reboot it harder to make sure i got the old version off the bottom of my shoe15:00
hallyn_apw: i don't touch the xen bits, but zul / smb should have answers15:06
apwhallyn_, it looks to be a libvirt issue to my eye15:07
apwhallyn_, which is odd as both ends of the relationship have the latest version, but they are still triggering paths with /xen-default/ in the middle15:09
hallyn_apw: right, ping zul15:10
apwta15:13
apwrtg, ok if i see this right with your patch reverted, the bits needed to do the separated headers are in the main rules15:19
apwrtg, so if you sync debian from saucy into the branch, then you should be able to just fix the control file15:20
rtgapw, ack15:20
apwrtg, if you want to just sync the debian in there, i can do the rest if that is easier15:20
apwrtg, if you are doing it there are two places, the control.stub.in for the naming of the main package, and flavours.stub for the Depends on the flavour headers15:21
rtgapw, you gonna push your changes to master-next ?15:22
apwrtg, i am saying that what was there before your patch should be sufficient15:22
rtgapw, oh, ok.15:23
apwrtg, so there are no changes to add, it is in there15:23
apwthe key components are the indeppkg and its use on link-headers, which is in there15:23
apwplus of cours your control changes, but htey are branch specific15:23
rtgapw, when I synced before there seemed to be a lot of differences, though a lot was whitespace.15:23
apwyeah those branches are on very very old base, i assume you just replaced it completly15:24
apwwhich ought to work15:24
rtgapw, I'm going to15:24
apwrtg, as you are doing manta, shall i do the same to mako15:25
rtgapw, ok, so I slammed HEAD on master-next in order to drop the platform names patch. I'll update manta accordingly15:25
rtgapw, yeah, go ahead and do mako15:25
apwrtg, lets see if a naive conversion just works15:29
rtgapw, a naive rsync clobbers debian/rules.d 'cause the indep headers package name changes aren't in master-next15:34
apw?15:35
rtgUBUNTU: [Packaging] make the common headers SRCPKGNAME prefix15:35
* apw waits on his build15:35
apwthat is in there ?15:36
* apw lets his test build complete15:36
apwthe header link stage looked to have the right names at least15:37
rtgapw,  ok, those changes are _already_ in master-next. never mind.15:37
apwyeah, master next has them, but they do nothing cause the src package is called linux15:38
rtgapw, well, it JFDTRT15:38
apwi think it does indeed, waiting on the final bits with DI disabled15:39
apwsome of our improvements to the debian/rules* have been worthwhile :)  even if kamal hates it15:39
plarscking: are you around perchance?15:50
plarsor someone that can take a look at http://reports.qa.ubuntu.com/power/eventstat/image/14/machine/1/task_type/all/details/15:50
ckingplars, yep, I'll peek at it15:50
plarswe are seeing a *huge* increase in events from swapper15:50
plarswe've had some issues in the automation that kept it from running the past few days, so it may not have just been today15:51
apwrtg, ok i have pushed my mako redux to saucy repo ... perhaps look it over15:51
rtgapw, ack15:51
apwrtg, shall i do the other one15:51
rtgapw, I'm working on manta15:52
apwgrouper15:52
rtgapw, rock on15:52
ckingplars, how do I access the raw logs on the tests?15:55
rtgapw, I think you lost the gcc-4.7 changes to mako in debian/rules.d/0*15:56
apwrtg, mako did it in Makefile not in the debian bits15:56
rtgah15:57
plarscking: click on one of the tasks, then the build id, or just go here: https://jenkins.qa.ubuntu.com/job/eventstat-saucy-desktop-amd64-install-idle-vm/4/?15:57
apwrtg, which reminds me, if you do it where you do, you need to add $(CROSS_COMPILE) before gcc-4.715:57
apwi had that on my manta-apw branch15:57
ckingplars, ok - got it- thanks15:57
rtgapw, yeah, just forgot15:58
apwrtg, i'll switch my branches to match yours next15:58
apwthough i think doko hinted it may not be needed any more15:58
apwi must check with him15:58
ckingplars, I'm confused by the results that are 20120425,  I didn't know we had this running last year. is that a bug in the time stamp?16:01
ckingalso, it's kinda hard to see what changed in terms of kernel version being tested, it's kinda hard to find that info quickly16:02
apwrtg, oh, hmm, i think we should be overriding REAL_CC not CC in the 3.4 branches ...16:03
plarscking: those with the old dates are probably from the quantal/precise runs I did.. I didn't realize that the dashboard would show them in the same spot16:03
plarscking: I can take any feedback you have to the people working on the dashboard if you'd like16:04
ckingplars, it would be useful to have the kernel version info there just to make life a little easier ;-)16:04
plarscking: we test the whole image, and we're looking at these events not just in kernel but apps too16:05
plarscking: it should be easier to derive versions of all these things from somewhere shouldn't it?16:05
ckingplars, sure, it would be nice to figure out easily what's changed16:05
rtgapw, I think that is an android addition in your mako Makefile16:06
rtgits not in manta16:06
ckingplars, the std.dev. looks very broken for some of the data, for exampe cupsd, the min/max is a very small  and the calculated std.dev is 300, I make it to be ~0.3616:12
josephtcking: that's std.dev % or std.dev/avg16:15
ckingmind boggles16:15
ckingjosepht, is it a a population std.dev  in % then?16:18
josephtcking: yes, the population std.dev is in there too, one column to the left16:19
ckingjosepht, yep, that's good then ;-)16:20
ckingbah, /me needs to use stdevp() in libreoffice next time16:21
* ppisati goes out for a bit...16:24
ckingplars, so what's the official procedure when issues like this get spotted? do bugs get filed and if so, who files them?16:25
=== masACC is now known as maswan
plarscking: in theory, anyone could see it out there and open something on it16:32
plarscking: I try to check it regularly, but we have a LOT of these sort of things to check on16:32
plarscking: but today was the first time it came up for me since the job started going again, and I noticed something off there. After our talk last week I thought it best to bounce if off you first to make sure it was really a bug16:33
plarscking: now that the other results are on that dashboard, I do notice that the events for quantal and precise looked pretty high too, so maybe we got a lot better during raring?16:33
ckingplars, I'm not sure, the rate coincides with the 250Hz tick interval, so I'm not sure yet16:34
plarscking: and I did file a bug for the comiz/gnome-screensaver issue you pointed out last week also16:35
ckingplars, thanks ;-)16:35
plarscking: it's encouraging that the stddev was so low in quantal and precise, so once that's fixed we should see much more stable data for saucy16:36
plarscking: so should I just open a bug on this for you to look at? Can I assign it to you or should it go to the team?16:44
ckingplease open it, assign it to me, also, I'd like to see how it changes over time too16:45
ckingplars, http://jenkins.qa.ubuntu.com/job/power-saucy-desktop-i386-power-test-1/1/artifact/qa-power-testing/results/raring-power-amd64-2013-05-07_14:52:25-power_consumption.json - this has the name "raring" but in fact it is a suacy test - that's a bit confusing 16:54
plarscking: I'll take a look16:55
ckingta16:55
plarscking: I think there's some environment variables that get set for that stuff16:56
ckingutah-tastic16:56
plarscking: actually this is a variable that the kernel tests want set16:57
ckingah16:58
ckingoh well, whatever16:58
plarscking: I'll change it for now, and try to remember to come back to it at some point and think about whether there's a better place I can inherit it from so that it picks it up automagically16:58
ckingrighteo16:58
plarscking: regardless of the name, it *is* running on saucy  though :)16:58
apwplars, how do i find the kernel version for these tests?17:22
plarsapw: there is no way for you to find out the kernel version that was in a specific day's image?17:24
plarsshould be in the manifest I think17:24
apwand that is in your results, or i have to download 800M of image to find out17:25
plarsapw: no, should be more like a 50k file on cdimage17:25
plarsapw: but I agree it would be nice if it was easier to find, we'll see what we can do there in the future17:25
apwperhaps a link direct to the manifest for the image17:26
rtgapw, pushed and uploaded saucy manta. you could delete the manta-apw branch17:52
apwrtg, gon18:59
apwgone18:59
=== lool- is now known as lool
infinityapw: That same headers fix is needed for mako and grouper too.19:14
apwinfinity, all true, and they are both done and pending for the next uploads20:18
apwinfinity, i don't think there is any gain from uploading for just that though ... 20:18
infinityapw: Fair enough.20:26
