seb128doko, hey, I noticed your merged packagekit 1.0 again ;-) ... do you plan to port/fix aptdaemon?06:21
pittiwasn't the bigger blocker click?06:22
seb128doko, also it breaks click still06:22
seb128pitti, we sort of agreed that it would be ok to break them for a while because they don't plan to base any product on y06:23
pittiah, ok06:23
seb128but we should sync up again with them to make sure it's still ok06:23
pittiand moving to snaps at some point, I figure06:23
seb128why is autopkgtest for aptdaemon 1.1.1+bzr982-0ubuntu14: amd64: Ignored failure,06:24
dokoseb128, hrm, thought it would be safe after the lts ...06:24
seb128that failure should absolutly not be ignored06:24
seb128it's an abi break that makes it fail to import packagekit06:24
pittiaptdaemon's tests have been failing for a long time in xenial already06:25
seb128well in that case they rightly fail06:26
pittiwould be good to fix them indeed, so that they become useful again to detect regressions06:26
pittii. e. to succeed in yakkety-release06:26
pitti(or even xenial)06:26
seb128meanwhile can we make sure it's blocked in proposed?06:26
pittiseb128: easiest is to have a bug against packagekit and tag it block-proposed06:27
pittiI don't want to remove the force-badtest, as this would hold up a lot of unrelated stuff then06:28
dokohmm, click has an older version in -proposed than in -release?06:28
seb128doko, pitti, anyway, https://errors.ubuntu.com/problem/0cbdb94861b90a2bf18c183fb3031ed81f6bb5a7 is one of the issues with aptdaemon/new packagekit06:30

pittiSaviq: is it really necessary to micro-split the packages that way?07:16
Saviqsry, first time /me doing this07:16
pittithey seem to have similar dependencies and each new package just ships a single new driver07:17
Saviqpitti, I'm afraid I can't answer that, but they've been split up more and more as they went, I'm sure there were some reasons for that07:18

SaviqRAOF, <pitti> Saviq: is it really necessary to micro-split the packages that way? (that's re: mir)07:25
pittiok, armhf autopkgtests are now limping along on 4 lxd slaves in scalingstack, but they commit suicide every hour or so07:25
pittiI might have to disable armhf autopkgtests until the CI lab comes back07:26
RAOFpitti: Oh, you were referring to the new graphics-mesa-kms9 vs graphics-mesa-x9?07:27
pittiRAOF: and -android907:28
RAOF-android9 pulls in android dependencies?07:30
RAOFMerging -kms9 and -x9 would be painless; *technically* they have different dependencies, but in practise libGL pulls in X anyway...07:31
pittiRAOF: do -android{5,8,9} have different deps?07:33
RAOFpitti: No, but they're all superceded.07:33
pittiRAOF: ah, so those will be NBS? good07:34
RAOFOr, rather, we've got 2 ABIs in play - client platform ABI and server platform ABI; there'll be exactly one mir-platform-graphics-* for each platform, and exactly one mir-client-platform-* for each platform.07:35

pittiit's hopefully not a permanent change15:14

pittiapw: it's the only thing that's left from initscripts that we actually use; I'm working on dropping deps to initscripts so that we stop installing it by default, and wonder if I should put an equivalent unit into systemd or not15:42
smoserpitti, something else is at play here.15:43
apwpitti, we use that to boot in performance and drop back to something less batter sucking ... and the kenrel is still in performance by default15:43
smoser$ pastebinit /lib/systemd/system/cloud-init-local.service15:43

smoser$ tail -n 10 /usr/bin/cloud-init | pastebinit15:44
pittiapw: i. e. I wonder why we are the only distro doing somethign like that15:44
apwpitti, it was something that keybuk drove in, and it has never been revisited since15:45
pittiapw: anyway, it's simple to port; I'll probably use a Type=idle so that it goes to ondemand as soon as boot is done, istead of a static "1 minute", I just wondered if the kernel still needs that kind of help15:45
smoser http://paste.ubuntu.com/16524007/15:45
xnoxpitti, please steal15:45
smoserso i suspect that something in the cloud-init's imports is messing up the PYTHONHASH or something so it goes back to slow.15:46
apwpitti, yeah it is pretty unclear for sure, would you file a bug on linux to review that and let me know, i will find someone to think about it15:46
apwpitti, but in the short term, making it an idle systemd unit sounds much better anyhow15:46
apwa i know it makes my lappy hot during boot :/15:47
pittiapw: ok, so port to a unit in the short-term, and revisit if defaulting to "ondemand" works better now (after all, some 10 years have passed..)15:49
pittimaybe 815:49
Odd_Blokesmoser: If you want to test the imports, you could (probably) move them all in to that if statement after the startup time is written out.15:50

cpaelzerHi, I know there are always all kind of super-skilled people around - for those of you who love gcc/ld to its darkest depth - you might take a look at http://stackoverflow.com/questions/37351699/how-to-create-both-so-files-for-two-circular-depending-libraries - there seem to be no good answer to that out there yet so I asked it openly16:53
cpaelzerI'm giving up on it for now and let the weekend try to distract me from it :-)16:53
smoserpitti, just for a summary of above using PYTHONHASH does not seem to affect all things.17:02
smoserfor example, 'import tempfile' does17:02
smoser from random import Random as _Random17:02
smoserand that seems hits the same first boot hang even with PYTHONHASH set.17:03
Odd_Blokesmoser: What do you see without that set at all?17:05
Odd_Blokesmoser: Because I suspect you are working around the Python _startup_ issue, and then hitting a separate (but very much related) random module issue.17:06
smoseryeah. i think so too17:06
smoseri can take out the Environment and see17:06
Odd_Blokesmoser: I've filed https://bugs.launchpad.net/cloud-images/+bug/1584147 (which also affects cloud-init).17:12
ubottuLaunchpad bug 1584147 in cloud-init (Ubuntu) "cloud-init hangs on boot as Python waits for sufficient randomness to start" [Undecided,New]17:12
smoserOdd_Bloke, so setting PYTHONHASH *does* help.17:13
smoserat least in a single test here17:13
smoserbut clearly doesnt make it all magic17:13
Odd_Blokesmoser: I've added a comment with a high-level summary of what you've discovered; please feel free to flesh out with details. :)17:15
TJ-Why would "Failed to connect to Mir: Failed to connect to server socket: No such file or directory" be reported when executing an X application from the terminal, launched by another (sudo) user, with e.g. "sudo /usr/bin/env DISPLAY=:0 XAUTHORITY=/home/<user>/.Xauthority xclock" - do we need to copy more of the target users' native environment? any in particular? presumably this is some kind of fallback19:31
TJ-if the X session isn't found?19:31
dobeywhere are you trying to do that?19:32
TJ-from a VT. On my system (Ubuntu+Unity) it works fine. On another system using, I think, Lubuntu, it gets that error. Obviously Mir isn't installed, but it feels like a fallback if the X server/session for the target user cannot be located19:33
dobeywell i'm pretty sure xclock doesn't link to libmir19:35
sarnoldTJ-: I got that same error message trying to run evince via ssh -X https://bugs.launchpad.net/ubuntu/+source/evince/+bug/157330019:35
ubottuLaunchpad bug 1573300 in evince (Ubuntu) "ssh -X X11 forwarding doesn't work" [High,Incomplete]19:35
TJ-no, it's something in the underlying libraries obviously. I've not pulled the sources of the libraries as yet to search for the string19:35
sarnoldTJ-: I never got around to debugging this thing :/19:35
dobeywell, xclock is a pure x app19:36
TJ-sarnold: right; I've seen some similar reports but no bug reports as yet.19:36
dobeyit doesn't link to gtk+ or qt, and the X libs don't link to mir19:36
sarnoldxclock is a genius test case :) pretty simple, no churn19:36
TJ-dobey: xclock is just an example19:36
TJ-this is about the session-level env I think19:36
dobeyTJ-: sure, i'm just trying to figure out what could possibly cause something that does link to mir, to be run in that case19:37
dobeyand i just don't see anything19:37
TJ-I suspect its the XDG_* vars19:37
TJ-looks like bug 146326319:39
ubottubug 1463263 in Ubuntu "ssh-based X11 forwarding not working in 15.04 following upgrade from 14.10" [Undecided,Confirmed] https://launchpad.net/bugs/146326319:39
dobeyTJ-: why not strace and follow the forks/threads to see what else gets run?19:39
TJ-dobey: I suspect the failing Lubuntu system doesn't have those XDG_ vars that this Ubuntu has in each user's session19:39
TJ-dobey: I don't have direct access to the failing system right now19:39
dobeyi don't understand what's failing exactly. you ssh to a remote system and then try to run something on that remote system's own local display?19:40
TJ-interesting that bug has the quote "The "gdk_mir_display_open" error is just GDK/GTK trying to use Mir because it found no X11 server ($DISPLAY is blank)."19:40
TJ-dobey: No, ssh is sarnold's issue :)19:40
dobey*shrug* ssh -X works fine here19:41
TJ-dobey: 2 completely unrelated separate systems here, trying to use the same mechanism to cause a (yad) window to be displayed in "user1" X session, triggered by "user2" non-GUI script doing "sudo /usr/bin/env DISPLAY=:0 XAUTHORITY=/home/user2/.Xauthority yad ...args..." ... I use xclock just to test it19:42
TJ-user2 has sudoers NOPASSWD rights to /usr/bin/env so no user prompting is required19:43
sarnoldTJ-: are perms on /home /home/user2/ and /home/user2/.Xauthority all correct?19:43
TJ-the background to this is some automated scripts the bring up a public Internet connection (wifi) and then a secure VPN, and inform the user whats' going on and, if the public internet is detected to have a captive portal, uses that mechanism with xdg-open http://some.domain/ to cause "user1" to see the captive portal login page19:44
TJ-sarnold: yes, totally separate, and thatts why 'sudo' is being used, to ensure access to the files19:45
TJ-I'll be in front of the Lubuntu system on Sunday, but hopefully I can get some background on this before then19:45
dobeyTJ-: and the user was definitely logged in on the remote machine?19:48
TJ-interesting  bug 1433165 suggests it could be triggered by an apparmor profile19:49
ubottubug 1433165 in evince (Ubuntu) "evince fails to run due to a gdk_mir_display_open" [High,Confirmed] https://launchpad.net/bugs/143316519:49
TJ-dobey: yes, it's complicated, but user1 is the UID 1000 default user account ... user2 is a 2nd account used to contain the scripts and execute them such that user1 cannot mess them up. user2 has certain sudoers NOPASSWD permissions to run a few system commands via sudo with no need of user interaction19:51
TJ-As I said, this looks to be partially due to the failing system being Lubuntu, so potentially a few things are different in the session env19:52
dobeyTJ-: as i said, i think you should strace to see where the actual failure happens. xclock and sudo don't link to libmirclient, so they can't possibly be trying to open a mir socket (unless of course the xclock is actually a link to some other app, which does link to libmirclient).19:54
TJ-it'll be the gtk/gdk libraries I presume20:00

TJ-aahhhh gdk/mir/gdkmirdisplay.c20:03
dobeywell yes, obviously gtk+ has support for mir20:04
dobeybut that doesn't explain your issue with xclock20:04
dobeyxclock does not use gtk+20:04
dobeyor gdk20:04
sarnoldthere is a surprising number of libraries there though http://paste.ubuntu.com/16534039/20:06
sarnoldmy guesses, libfreetype, libfontconfig20:06
sarnoldalso why xclock needs a bloody xml parser .. *sigh*20:07
TJ-ignore xclock, that is misleading. The first of several real commands that fails is xdg-open (synaptic is another one) ... xdg-open is a shell script that runs different programs based on the DE. for LXDE it used pcmanfm which is linked to gtk20:08
dobeysarnold: apt-cache rdepends libmirclient9 doesn't show fontconfig or freetype as needing it20:08
sarnolddobey: ldd20:08
sarnoldoh I see, read too fast20:08
sarnoldor rather, read too poorly :)20:08
dobeyTJ-: well if it's misleading, that's your fault. you said it didn't work and gave you that mir error. if that's not true, why did you say it? :)20:09
TJ-that explains the error message, but it'll take some time to work backwards to figure out what is missing in the environment that caused the code to fall through to the mir code20:09
dobeywell, it couldn't connect to the X display20:10
TJ-dobey: I gave it as an example of a quick test we tried to minimize the externals. But, the actual scripts use xdg-open yad and others, so tracing xdg-open now I know where the error is coming from, will actually help us find a workaround20:11
Saviqwho has access to snakefruit and could follow https://wiki.ubuntu.com/ProposedMigration/AutopkgtestInfrastructure#Re-running_tests to re-run the unity8 tests with --all-proposed? it's trying to build old unity8 with new unity-api and that won't work20:19
Saviqthe unity8 tests for http://people.canonical.com/~ubuntu-archive/proposed-migration/update_excuses.html#unity-scopes-api I meant20:19
Saviqas we're in a chicken'n'egg situation20:19
sarnoldSaviq: just curious does that mean one of the packages is missing a version dependency of some sort?20:20
Saviqsarnold, we never came up with the right way to encode those dependencies, we have a unity8 B-D: unity-api-dev >> $version20:22
Saviqand a new unity-api-dev can break unity8 build20:23
lpotterwell... my update to xenial went better than the last time I tried...20:23
dobeySaviq: it's only an issue becasue autopkgtests rebuild unity8 right?20:24
Saviqdobey, bits of it still, yes20:24
Saviqwe're thinking how to avoid that20:24
Saviqnow that I think of it if we build-depended on a virtual package provided by unity-api-dev (is it even supported to B-D on a virtual package?), it would make it better20:24
Saviqbecause a "breaking" unity-api-dev wouldn't Provide that any more20:25
dobeyhmm, well, unity8 seems to be flagged as always failing on yakkety, at least in my pay-service silo: https://requests.ci-train.ubuntu.com/static/britney/yakkety/landing-056/excuses.html20:25
Saviqdobey, yeah but it's uninstallable20:26
Saviqbecause of http://people.canonical.com/~ubuntu-archive/proposed-migration/update_excuses.html#unity-scopes-api20:26
dobeybut http://people.canonical.com/~ubuntu-archive/proposed-migration/update_excuses.html doesn't show that any more20:26
Saviqi.e. https://requests.ci-train.ubuntu.com/static/britney/yakkety/landing-058/excuses.html20:26
Saviqunity8-common/amd64 unsatisfiable Depends: unity-scopes-impl-1220:27
Saviqand that is provided by unity-scope-shell, depending on the above unity-scopes-api, which regressed unity8... you know the drill...20:27
