brendandhow do i get ubuntu-bug to work with the backports kernel package?13:17
apwgive it the name of the binary package perhaps ?13:17
brendand'not an official ubuntu package'13:18
apwbrendand, not sure waht to say to that, it is damn you apport13:20
brendandso anyway to rip the logs and store them locally for uploading later13:21
brendand?13:21
brendandi.e. what do i do if the bug is *no frickin network*!13:21
apwyou can say --save <filename> in that case13:22
apwand submit it later13:22
brendandactually wrong question. how are you guys going to be triaging quantal backports bugs if no-one can give you logs?13:23
brendandassuming everyone will be met with the error above?13:23
apwwell i guess as its not released its not official yet13:23
brendandapw - do i need to advise my team then that they need to get logs manually? it would be good to know if there's any way apport can be enabled for the quantal backports package13:28

apwsmb, do you still use squid-deb-proxy ?13:54
smbapw, Yes, the one got pulled in by orchestra. (though I think its the normal one). Why?13:55
apwsmb, have some bits to try using ipv6 (including link locals) for squid-deb-proxy13:56
smbapw, That would require actually using ipv6 and that I don't do13:57
apwsmb, i bet you have link-locals13:58
apwand you only having link-locals is one of the test cases13:58
smbapw, Yes I would have those probably... if those are used... 13:59
apwsmb, can you paste me the output of: avahi-browse -kprt _apt_proxy._tcp14:00
smbapw, I can try, but you would better mail me what I should do cause I first want to finish my current task which needs a bit of thingking.. that output is nil14:01
apwsmb, then you arn't using squid-deb-proxy14:02
smbapw, Ok, could be. Don't have a package like that installed. Its just squid3 and some special config to proxy deb14:03
apwsmb, yeah you have a hybrid14:05
hertonapw, not sure if I misread here, just quick checking,  package_prefixes() function doesn't seem to be called anywhere in debian/scripts/misc/getabis, on getabis patch14:09
ckingbah, gotta kick my AP again14:12
hertonapw, nevermind :P, saw next patch14:13
apwherton, heh ...14:16
bjfcking, you still need waldorf power cycled?14:18
ckingbjf, yep, I locked it up well and good14:19
bjfcking: done14:20
ckingbjf, ta14:20
apwherton, bah, seems zinc cannot get to ppa.l.n ... so although i can configure it, it won't work14:54
hertonapw, indeed, I had this problem before, I always had to use --local with maint-startnewrelease because of it14:55
apwwe should get rtg on the case14:55
apwherton, but adding "http://ppa.launchpad.net/canonical-kernel-team/ppa/ubuntu/pool/main/l/linux" to repo_list in debian.master/etc/getabis should do the trick in the local case i believe14:56
hertonyep, should work just with the extra url I believe too14:56
apwherton, perhaps you could test that and let us know, when you next need to14:56
apwand in the mean time we can get zinc sorted out14:57
hertonok14:57
rtgapw, can't you run that from gomeisa or tangerine ?14:57
apwrtg might be able to hmmm14:57
rtgthat would be my prference14:57
ericm|ubuntusforshee, around?14:59
sforsheeericm|ubuntu, yep15:00
hertonapw, may be we should not enable always the ppa on the script, perhaps adding a switch/option, if we also assume that we could have some "dirt" in the ppa15:00
ericm|ubuntusforshee, found glided in glidepoint is waking up every 10ms15:00
ericm|ubuntusforshee, that seems to affect much the power consumption on this Dell machine,15:00
sforsheeericm|ubuntu, quality stuff it sounds like15:00
apwherton, you specifiy the exact version you want, so wherever it is it will be the right one15:00
apwif its not there it will move on to the real archive15:00
ericm|ubuntusforshee, saw several of your reply regarding ALPS touch, thought you may have some ideas15:01
sforsheeericm|ubuntu, I did some reverse engineering for some ALPS touchpads a while back, but I had access to the hardware15:01
hertonapw, yeah, almost impossible we will get same version but differing contents from the ppa and what is on official repo.15:01
ericm|ubuntusforshee, so do you know where's that glidepoint project and if it's open sourced?15:02
sforsheeericm|ubuntu, this is what I did: http://swapspace.forshee.me/2011/11/touchpad-protocol-reverse-engineering.html15:02
sforsheeericm|ubuntu, drivers/input/mouse/alps.c ?15:02
ericm|ubuntusforshee, nope - it's using glided which is packaged in glidepoint15:02
ericm|ubuntusforshee, that could be a FISH package though15:02
sforsheeericm|ubuntu, I'm pretty sure that's binary blob stuff that ALPS provided15:03
sforsheenot open source15:03
ericm|ubuntusforshee, yeah seems alike15:03
ericm|ubuntusforshee, that's good to know, at least we know who to blame then15:03
ericm|ubuntusforshee, thanks dude :-)15:03
apwherton, ok on gomeisa that works just fine, goes to the PPA first etc15:03
sforsheeericm|ubuntu, if it's what I'm thinking of it also doesn't use the native touchpad protocol15:04
hertoncool15:04
sforsheeericm|ubuntu, it's something more like the IMPS2 emulation like we used to have15:04
apwherton, you happy adding them or shall i produce some patches15:04
ericm|ubuntusforshee, btw - there seems to be many touchpad issues recently, most of which are related to the abnormal behavior after resuming back15:04
rtgapw, why is debian/scripts/misc/getabis different on Quantal vs Oneiric/Precise ? Shouldn't they all be identical ?15:04
hertonapw, feel free to go on, I'm right now working on ppisati ti-omap4 update15:04
hertonfor precise15:04
sforsheeericm|ubuntu, I recall an issue on synaptics a while back, but it should have been fixed15:05
ericm|ubuntusforshee, which one specifically?15:05
apwrtg, no they differ because pae is gone15:05
sforsheeericm|ubuntu, don't know. I just saw some discussion on linux-input. I thought someone from canonical reported the issue though.15:05

apwthey should be the same after patches ... /me checks15:06

apwapw@dm:~/git2$ diff -u ubuntu-{precise,quantal}/debian/scripts/misc/getabis 15:07
apwapw@dm:~/git2$ 15:07
apwrtg, ^^ yes after patching they will be the same15:07
ericm|ubuntusforshee, that's a weird issue - bad EC behavior I guess, but very specific, ayan's having a bunch of other weird issues15:07
apwrtg, they differ currently cause you added the firmware tracking in P and not Q15:07
sforsheeericm|ubuntu, I haven't heard anything about them, but if it's a regression we can always bisect15:07
rtgapw, ok, thats what I'm seeing as well15:07
apwand after these patches O,P and Q will be the same15:08
rtgapw, you duidn't send the firmware tracking patch for Q, thought, right ?15:08
rtgthough*15:08
ericm|ubuntusforshee, I don't think they are regressions, I'll talk w/ ayan a bit more on them, and could possibly bother you for some thoughts15:08
sforsheeericm|ubuntu, sounds good15:09
rtgapw, ok, I added the firmware tracking patch to Q and now its identical to P15:09
apwrtg though i already pushed those to Q didn't i?15:10
rtgnope, I had no conflict15:10
apwbah15:10
rtgapw, hence my confusion15:11
apwrtg, which now makes sense ... /me will sort15:11
apwrtg, ok done15:12
rtgapw, yeah, Q is still missing the 'UBUNTU: [Config] getabis -- series uses linux-image-extra' patch15:12
rtgapw, nm, looks good now15:12
apwrtg there now15:12
apwrtg, i reset them back off earlier cause while i sorted the bug numbers, clearly forgot to push them again15:13
rtgapw, so, do we also have to fix any of the topic branches? Perhaps only Oneiric/Precise ?15:17
apwrtg, i don't think so cause none of them have a split ?15:17
apwit was only virtual in O and P anyhow that has a split15:17
rtgapw, but they are rebase branches and will pickup the new getabis which now requires an input parameter15:18
apwrtg, nope i very specifically made it default to 'linux-image'15:18
rtgapw, ok, didn't notice that.15:18
apw__package_prefixes="linux-image"15:18
apwso that we'd not have to bother on older releases if it went there15:19
rtgapw, ok, I see where you did that now15:19
rtgapw, where do you annotate why a config option is inconsistent ?15:28
rtgfor example, ppisati wnats to make CONFIG_SND=y for omap, but its gonne be =m for everything else15:29
apwrtg, when its going to show up in the kernel configuration review, that in kteam-tools/devel/OVERRIDES15:30
apwrtg, in a similar but subtly different format to the enforcer15:30
rtgapw, ah. didn't think to look there.15:30
apwrtg, note that now has cut support using the /, see other examples15:30
apwCONFIG_SND p policy<(flavour omap &/ value y) | value m> note<REASON>15:31
apwrtg, something like that15:31
rtgapw, blech!15:32
apwrtg, indeed not pretty, its a work in progress, the p bits on its way out but not yet complete15:32
rtgapw, I'm wondering why we don't carry this info in the kernel tree ?15:33
apwrtg, i was just wondering the same thing myself ... i will add that to the agenda, i think its likely we do want to do that15:33
rtgagreed. after all, the config options are kernel specific15:33
apwrtg, indeed and in places i have wanted to have different answers per release ... so clearly they should be in the tree now we have a maximal set15:34
* ppisati goes out for a bit15:34
apwrtg, added15:35
rtgapw, thanks15:35
apwppisati, what are these manditory builtin modules for omap sound, got a simple list15:55
apwrtg, is that what you are doing to OVERRIDES or ... ?15:55
rtgapw, they should be listed in the Precise patch description15:57
rtgSND_OMAP_SOC, SND_OMAP_SOC_MCBSP and  SND_OMAP_SOC_OMAP3_BEAGLE =y15:57
apwahh ok, rtg and are you adding them to the OVERRIDES or shall I15:57

hertonrtg, I think "retrieve ABIs from PPA as a last attempt" could be commited on oneiric as well19:11
hertonactually on all relevant trees. I'm not sure changing maint-startnewrelease or drop its usage, anyway one of the two choices must be done19:14
rtgherton, I like having the PPA path in the getabis script since it appears that the use of the non-virt PPA is permamnent.19:16
rtgherton, I actually didn't know about maint-startnewrelease,  but I think adding the ckt PPA URL serves the same purpose.19:21
hertonrtg, yes. well we always used it doing the stable updates, it automatically fetches the packages, removes the old abi/copies the new one, and does the commit, just automate things a bit more.19:23
rtgherton, yeah, after looking at the script it automates a bunch of what I've always done by hand.19:23
rtgplus some other checking19:24
hertonI think we could just modify it to use the getabis from the in kernel tree, or just add same functionality to the in tree scripts19:24
