dufluRAOF (or anyone), the gsequencer build failure looks like its own fault. It uses fakeroot without having a build dependency on it.07:09
dufluNot pulseaudio's fault07:09
RAOFduflu: care to fix gsequencer, then? 😉07:10
dufluRAOF: It has a whole new version waiting in proposed07:10
dufluMight not need to07:10

didrocks* Implemented new sound option in Gnome Control Center (will be a minimal ubuntu patch) following Allan's design and GNOME Tweaks.14:33
didrocks* Mentored GCI. We got 2 large contributions: new getting started blender videos adapted to our patch. Needs packaging (video generation when building) though. The second one is notifications on Terminal. Not fully working yet but vte & g-t Fedora's patches are applied. Helped the students with pointers, tutoring, packaging 1o1…14:34
didrocks* Caught up on every PR/issues for the communitheme, did some comments, proposed some fixes.14:34

jibel  - Good news: Found that clutter's frame clock logic needs the same kind of fixes as have recently landed in GTK.14:36
jibel  - Bad news: Not that much other than some shell animations rely on the precision of the clutter frame clock so experimental fixes to its precision so far don't yield any major visual improvement to everyday usage. I might propose changes to upstream clutter later. Not a shell priority any more, probably.14:36
jibel  - Presently: I am now working on generating some real-time profiles of gnome-shell to see where it blocks (or wastes CPU).14:36

didrocksthanks!14:48
tkamppeterOne problem: Need xnox to check the systemd problem.14:48
didrocksTrevinho: a question, I'm curious about your js GNOME Shell changes, do you have pointers?14:48
tkamppeterAnd need someone to sponsor my NEW packages.14:48
oSoMoNthanks jibel14:48
Trevinhodidrocks: they're related to https://bugzilla.gnome.org/show_bug.cgi?id=791233 but I didn't push the final patches yet14:49
ubot5Gnome bug 791233 in general "Various Javascript errors in accessing deleted object properties" [Normal,New]14:49
Trevinhodidrocks: as I've been discussing about the best design for them14:49
seb128tkamppeter, we talked about systemd with Steve, it would help if you could figure out a way to reproduce easily the bug that doesn't involve owning a specific printer or such ... do you think it's possible?14:50
seb128tkamppeter, foundations is going to look at it but it would make easier to debug if they could reproduce easily14:50
didrocksTrevinho: lucky you, you get reviews! :)14:50
Trevinhodidrocks: well, after pinging people a lot.....14:50
Trevinhodidrocks: and even after that not many really, well not specific as Jonas does14:51
didrocksTrevinho: btw, if you have an idea to replace the idle_add, I'm all ears14:51
tkamppeterseb128, probably any USB printer would serve, not only the concrete model I am using.14:51
TrevinhoI don't think a "I don't like it" is enough for a review :)14:51
didrocksTrevinho: yeah, it's really hard to get Shell reviews for the js part :/14:51
Trevinhodidrocks: I've been trying to think another way, let me go back to that14:51
didrocksTrevinho: would love to :)14:52
seb128tkamppeter, right, I'm not sure they own a printer, Steve doesn't travek with one for sure at least so having a script or something to simulate it would be nice14:52
seb128tkamppeter, could umockdev allows to do that?14:53
tkamppeterseb128, I think this is difficult, to have some software emulating the appearance of a USB device.14:58
tkamppeterseb128, where is Steve currently? In the Bluefin office?14:59
seb128tkamppeter, no, in south africa for the same sprint will and I are at14:59
tkamppeterIn South Africa, interesting.15:00
seb128tkamppeter, umockdev could do what you need to record/replay the event maybe?15:00
seb128tkamppeter, well I'm going to ask them if they can access an usb printer to debug15:01
seb128tkamppeter, did you try if the bug happens on Debian as well?15:01
tkamppeterWhat one can do is, right after the Sprint, buy a cheapo HP, like the DeskJet 2540, expensed to Canonical.15:01
seb128I wonder if other distributions are having the same issue and if not why they don't15:01
tkamppeterWhat is the venue in South Africa? A hotel?15:02
seb128yes15:02
tkamppeterAny printer which is around has a USB connector, you could reproduce the bug even if there is no working Linux driver for the printer.15:03
tkamppeterSo some printer in the hotel's business center or office could even help.15:04
tkamppeterSimply go with a laptop and a USB cable into the business center turn on and connect the printer and see what the computer does.15:04
seb128k15:05
seb128tkamppeter, umockdev allows you to record udev events and reply them to simulate devices like that15:05
seb128tkamppeter, https://github.com/martinpitt/umockdev15:06
seb128tkamppeter, but that's maybe not required in that case, should be easy enough to access a printer15:06
tkamppeterpitti has the solution for everything ...15:06
seb128indeed15:07
tkamppeterI want to have pitt back at Canonical ...15:07
seb128please do :)15:07
tkamppeterBut probably Canonical would have to big very high, like for a great socker player.15:08
tkamppeters/big/bid/15:09
pittitkamppeter: indeed, mocking the *presence* of a USB printer is fairly straightforward with umockdev15:13
pittimocking its *behaviour* is another topic, and that's currently rather brittle15:13
pittiI did some R&R on this a few years ago, and it kind of works, but maybe don't bet on it15:13
pittibut udev doesn't care about that, so the "static" udev properties are fine15:14
Laneyyeah it's just adding it15:14
Nafallohey! pitti didn't leave. he's here!15:15
pittisure! I can't leave my old desktop friends! :-)15:15
pittitkamppeter: I did a demo of this at this part: https://media.ccc.de/v/ASG2017-121-simulate_hardware_for_integration_testing#t=69715:17
seb128salut pitti15:17
pittitkamppeter: (< 10 minutes)15:17
pittiça va seb128 !15:17
seb128pitti, ça va, j'ai suis en Afrique du Sud mais j'avais la grippe, ça va mieux maintenant !15:17
seb128pitti, tkamppeter just needs the usb printer detection, it's for https://github.com/systemd/systemd/issues/710915:18
pittiseb128: ouch à nouveau ? quel dommage !15:18
seb128" Services asked for by UDEV do not get triggered #7109"15:18
seb128seems an escaping issue with paths or something like that15:18
seb128lennart added patches to that bug but they don't seem to work and it stalled since15:19
seb128pitti, et toi, comment ça va ?15:19
seb128pitti, oh et bonne année au fait :)15:19
pittiseb128: bonne année à toi aussi ! (mais je crois que nous à parlè déjà cette année :) )15:20
seb128c'est bien possible, je ne me rappelle de plus rien à cause de la grippe :p15:21
tkamppeterubot5 is not answering to GitHub bugs and GitHub is so common now.15:22
tkamppeterpitti, por favor, fale alemão, português, ou Inglês.15:24
Laney????15:25
Laneyneu Gymraeg?15:25
tkamppeterLaney, was sagst Du da?15:26
Nafallohohum. ska vi byta till svenska istället kanske? :-)15:27
tkamppeterLaney, which language is that?15:27
xnoxtkamppeter, i'm not sure how i can help you. The upstream bug report looks valid, and it is correct that you do not get the expected units started.15:29
Laneytkamppeter: japanese then welsh15:29
tkamppeterLaney, then Japanese is easy: ??? ?? ?????? ??? ??  ???? ...15:30
seb128xnox, we have been told you maintain systemd and such are the right person for looking at getting such issues resolved?15:30
xnoxtkamppeter, the only solution i can offer you is as follows - make all usb-printers trigger "setup-usb-printer.service" which correctly scans all printers and effectively does `systemctl start usb-printer@the-correct-path.service`15:30
Laneytkamppeter: you know that if you have ENV{SYSTEMD_WANTS}="foo@" then the path is added automatically?15:30
Laney+=15:31
xnoxLaney, the issue here, is that tkamppeter is adding SYSTEMD_WANTS... but the systemd escaping sysfs-path and unescaping it is not round trip save, and in the end the unit is triggered with a non-existant sysfs.15:31
xnoxdue to loss of too many or not enough backslashes.15:31
Laneyxnox: yeah, but you can remove some manual handling of the path by using this facility15:31
Laney70-printers.rules computes the path using a PROGRAM thing15:32
Laneybut AIUI that shouldn't be necessary15:32
xnoxhm, true.15:32
Laneyif you just want to start a template unit with the path15:32
Laneyhttps://www.freedesktop.org/software/systemd/man/systemd.device.html -> SYSTEMD_WANTS section15:33
tkamppeterxnox, Laney, and there are two types of USB printers affected: Conventional ones which need to have the auto-setup tool of system-config-printer started and IPP-over-USB ones which need to have ippusbxd started.15:33
LaneyI just made that change15:34
Laneyand it resulted in https://paste.ubuntu.com/26398450/15:35
Laneytkamppeter: the sysfs path there looks correct?15:35
xnoxLaney, i wanted to try to want an "ls" unit which would /bin/ls the whatever was passed to it15:35
xnoxunable to access /sys/sys/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.1 -> is the path right?15:36
tkamppeterLaney, you get /sys/sys/devices/...15:36
xnoxactually I guess i can do that on _all_ devices, to see where the paths break15:36
Laneyit's got an extra /sys15:36
Laneybut line 2 doesn't have that15:36
xnoxtkamppeter, does udev-configure-printer adds on?15:36
xnoxJan 16 15:34:09 raleigh.local udev-configure-printer[18659]: add /sys/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.115:36
xnoxJan 16 15:34:09 raleigh.local udev-configure-printer[18659]: unable to access /sys/sys/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.115:36
Laneyand that is a print of argv[n]15:37
Laneyso I'm guessing u-c-p is adding it15:37
xnoxcause yeah, it is called with /sys, and then it changes to /sys/sys?15:37
tkamppeterLaney, originally, the s-c-p tool was called with /devices/...., your new method seemas to have called it with /sys/devices/...15:37
Laneyyeah that must be a difference15:37
Laneyso I guess this is a fix/workaround, if you remove that prepending?15:37
tkamppeterLaney, looks like so.15:38
xnoxmaybe the tool should check if starts with /sys do not add an extra /sys -> to keep it compatible with both old and new world orders15:38
tkamppeterLaney, what exactly did you change?15:39
Laneytkamppeter: ACTION=="add", SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ENV{ID_USB_INTERFACES}=="*:0701??:*", TAG+="udev-configure-printer", TAG+="systemd", ENV{SYSTEMD_WANTS}+="udev-configure-printer@"15:39
LaneyI would guess the old way has some delicate problems with quoting15:42
tkamppeterLaney, will this still use the file /lib/systemd/system/udev-configure-printer@.service?15:42
tkamppeterLaney, or does it call the udev-configure-printer utility directly?15:43
Laneyit's starting that service15:43
tkamppeterOK. The systemd service is needed that the tool can spawn a daemon without systemd killing it.15:44
Laneyit should be equivalent to what you had15:44
Laneyexcept apparently you were getting the sysfs path without /sys before15:44
tkamppeterLaney, can you also check whether something similar is possible with /lib/systemd/system/ippusbxd@.service15:47
tkamppeterLaney, and the ippusbxd UDEV rule:15:49
tkamppeterACTION=="add", SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device" ENV{ID_USB_INTERFACES}=="*:070104:*", OWNER="root", GROUP="lp", MODE="0664", TAG+="systemd", PROGRAM="/bin/systemd-escape --template=ippusbxd@.service $env{BUSNUM}:$env{DEVNUM}", ENV{SYSTEMD_WANTS}+="%c"15:49
gQuigsif you need a real printer tester - I have a USB printer -  epson stylus cx 7450 if that helps...15:50
Laneytkamppeter: is that broken?15:52
Laneyseems okay to me15:54
tkamppeterLaney, checking now.15:56
tkamppeterLaney, I have the folowin in /lib/systemd/system/ippusbxd@.service:16:07
tkamppeter[Unit]16:08

tkamppeter# ExecStop= Not needed, ippusbxd stops by itself on shutdown of the printer16:08
tkamppeterand above-mentioned rule.16:08
Laneydoes it work?16:08
tkamppeterI have started "udevadm monitor --environment" and plugged in the printer.16:09
tkamppeterI get a lot of output with16:09
tkamppeterSYSTEMD_WANTS=ippusbxd@002:008.service 'udev-configure-printer@devices-pci0000:00-0000:00:14.0-usb2-2\x2d1.service' printer.target16:09
tkamppeterin it, but ippusbxd does not get started.16:10
Laneywell that service name looks right to me16:12
tkamppeterBut if I enter "sudo systemctl start ippusbxd@002:008.service" ippusbxd gets correctly started. This should usually go automatically.16:12
Laneytake a look in the journal16:12
tkamppeterLaney, Which command do I use for that?16:13
Laneyjournalctl -e16:13
Laneylook for stuff that happened when you plugged it in16:13
Laneyprobably Starting Daemon to make IPP-...16:13
tkamppeterIt says "Jan 16 14:06:02 till-x1carbon kernel: usb 2-1: usbfs: process 16465 (ippusbxd) did not claim interface 0 before use"16:17
tkamppeterLaney, ^^ but ippusbxd can be started normally from the command line or when manually starting the systemd service.16:17
Laneydon't know what that means but it looks like systemd did start the service for you16:17
Laneyis that a race condition?16:18
tkamppeterLaney, perhaps. I will remove the 70-.. UDEV rule and see whether this sokves it.16:18
Laneytry adding ExecStartPre=/bin/sleep 5 or something?16:20
Laneydon't forget to systemctl daemon-reload after editing units16:20
tkamppeterLaney, now it works, but strangely I get again16:21
tkamppeterJan 16 14:19:44 till-x1carbon kernel: usb 2-1: usbfs: process 16931 (ippusbxd) did not claim interface 0 before use16:22
tkamppeterand this time the daemon is running though, but as PID 16938.16:22
tkamppeterWill try the  ExecStartPre=/bin/sleep 516:23
Laneydo you see that when you start it yourself?16:23
Laneysounds to me like it is not on systemd's side anyway (i.e. if you see that message, systemd has started the service for you)16:24
tkamppeterLaney, there is some hidden race condition.16:38
tkamppeterI have removed 70-printers.udev, so there is only 55-ippusbxd.udev.16:39
tkamppeterLaney, without the sleep the ippusbxd starts sometimes sometimes not, also for sleep 1 or sleep 2.16:39
tkamppeterLaney, With spleep 3 it never starts.16:40
tkamppeterIn any case when ippusbxd starts, there is this "usbfs: process 16931 (ippusbxd) did not claim interface 0 before use" and ippusbxd starts with another process number.16:41
LaneySounds like ippusbxd is using libusb wrong16:44
tkamppeterLaney, ippusbxd directly started from the command line starts reliably, also when starting the service manually, ippusbxd starts reliably.16:46
tkamppeterLaney, also, in the cases when ippusbxd does not start after plugging the printer, journalctl -e shows no hint that the service gets started. The "Starting Daemon to make IPP-over-USB printers available as network printers (001:001)" line does not appear.16:48
Laney????????????????????????????????????????????????????????????????16:48
Laneywhy are you telling me about this random message if it's not starting?16:49
Laneyhow can it be printing a message in that case :/16:49
tkamppeterLaney, no I have confused you. Let us start over:16:55
tkamppeter1. Starting ippusbxd from the command line with the printer plugged always works.16:55
tkamppeter2. Plugging the printer gives "SYSTEMD_WANTS=ippusbxd@002:031.service printer.target" in the output of "udevadm monitor --environment", see full output in https://paste.ubuntu.com/26398883/16:57
tkamppeter2a. In most cases usbippxd does not start. Then in journalctl -e there is no message of the ippusbxd unit, not even "Starting Daemon to make IPP-over-USB printers available as network printers (001:001)".17:00
tkamppeter2b. In some cases ippusbxd actually gets started. Then journalctl -e actually shows "Starting Daemon to make IPP-over-USB printers available as network printers (001:001)" and even "Started Daemon to make IPP-over-USB printers available as network printers (001:001)", but it also shows "usbfs: process 16931 (ippusbxd) did not claim interface 0 before use" and ippusbxd starts with another process number. Looks like that ippusbxd got started twice (17:02
tkamppeterand only one of the two stays running).17:02
tkamppeterLaney, I hope it is easier to understand now for you.17:02
ogradid you try 8for laughs) to set Type=simple in your systemd unit ?17:03
LaneySure, but now I'm afraid I have no idea why the unit isn't getting started when it's in SYSTEMD_WANTS17:03
LaneyWhat does systemctl status <that service> show after it fails to start?17:03
tkamppeterogra, tried it and no change.17:06
ograwell, was worth a try :)17:07
tkamppeterLaney, udo systemctl status ippusbxd@002:033.service17:08

tkamppetertill@till-x1carbon:~$17:19
Laneyseems ok then17:19
xnoxtkamppeter, why is the number different? it got incremented due to plugging in / unplugging? 002:031 vs 002:034?17:20
tkamppeterLaney, journalctl -e still shows "kernel: usb 2-1: usbfs: process 19892 (ippusbxd) did not claim interface 0 before use", but the process number in there is of the ExecStart call and ippusbxd has actually another one, compare the status output.17:21
tkamppeterLaney problem is still that the service does not start automatically, when I plug in the printer, but starting manually works perfectly.17:22
tkamppeterxnox, yes. after each plugging the printer gets a new number, increased by 1.17:22
tkamppeterLaney, seems that we can ignore the "kernel: usb 2-1: usbfs: process 19892 (ippusbxd) did not claim interface 0 before use" message. It seems not to affect the problem.17:23
Laneyso it did something before forking17:23
LaneyI don't think that matters17:23
LaneyWhat is more interesting is why systemd doesn't start it *sometimes*17:24
Laneyno ideas on that though17:24
tkamppeterLaney, xnox, the problem is that the service appears in SYSTEMD_WANTS but does not get started.17:24
xnoxtkamppeter, i'd ratehr use --no-fork int he ExecStart and remove both Type=forking and GuessMainPID17:24
Laneymaybe show us the whole journal from before you plug it in17:24
tkamppeterLaney, xnox, and here in the ippusbxd case there seems also not to be any quoting/unquoting problem.17:25

tkamppeterLaney, xnox, the problem seems not to be affected by what the service unit does but by the service not started automatically.17:31
Laneyyeah that's the bit I don't understand17:31
Laneyplease just share the whole journal from just before you plug it in when it doesn't work17:32
Laneymaybe we can see something17:32
tkamppeterxnox, the /bin/systemd-escape call does not seem to cause any problem, as the SYSTEMD_WANTS shows the correct service name, the one which I can manually start.17:33
tkamppeterLaney, how to obtain the full journal in its maximum verbosity?17:33
Laneyjournalctl | tee till.log17:34

xnoxtkamppeter, i need the status of the device17:43
xnoxunit17:43
xnoxtkamppeter, cause if device unit is not "considered plugged" the wants are not started, as far as i understand....17:44
tkamppeterLaney, xnox: The manual start was successful.17:44
LaneyManually starting things isn't really interesting for this problem17:44
tkamppeterxnox, how do I get the log of the device unit?17:44
xnoxtkamppeter, can you plugin the thing; and find it in $ systemctl list-units ? and check if it is there or not?17:45
xnoxand then check status, if it is "loaded active plugged"?17:46
tkamppeterxnox, Laney: It contains17:52
tkamppeter  sys-devices-pci0000:00-0000:00:14.0-usb2-2\x2d1.device                                     loaded active plugged   Deskjet_2540_series17:52
tkamppeterregardless of whether the printer is plugged or not.17:52
tkamppeterSo it seems that the printer is not correctly unregistered from systemd on unplug, and so it does not get considered newly plugged.17:53
tkamppeterxnox, Laney: ^^17:53
tkamppeterxnox, Laney: First step would be to somehow manually reset it and see whether the service gets started automatically when plugging right after the reset.17:54
Laneydid you experiment with umockdev or something?17:55
xnoxtkamppeter, reboot? =)17:55
tkamppeterxnox, Laney, next step is to find a way that the status of the device gets reset/removed on unplug automatically.17:55
xnoxtkamppeter, run udevadm monitor to figure things out. but it usually monitors only things it knows about pre-plug. possibly a kernel driver bug.17:56
tkamppeterxnox, Laney: sudo systemctl daemon-reload removes the status.17:56
xnoxgood17:56
Laneyfor me it goes active / inactive corresponding to whether the printer is plugged in or not17:57
tkamppeterxnox, Laney: And plugging right after that starts the service automatically!!17:57
tkamppeterxnox, Laney: I have never "inactive".17:58
Laneysuggest restarting17:59
xnoxtkamppeter, maybe your printer is broken; or something else starts that holds up the device; i see other things starting e.g. colord-sane? what is up with that?18:01
tkamppeterLaney, xnox: turning off the printer has the same problem, no reset of loaded active plugged.18:02
LaneyI mean restarting your computer :P18:02
Laneybut now I'm off, can carry this on tomorrow if required18:02
Laneyhappy evening o/18:02
tkamppeterLaney, thanks, see you tomorrow.18:04
seb128Laney, have a nice evening18:04
tkamppeterxnox, do not know how colord-sane is working. It does not come fro me, but it seems to react on the presence of the printer, too.18:05
tkamppeterxnox, how can I stop that.18:05
tkamppeterxnox, in "udevadm monitor --environment" is nothing output at all during unplug of the printer. Is this correct?18:08
tkamppeterxnox, is there some way to see whether a device like sys-devices-pci0000:00-0000:00:14.0-usb2-2\x2d1.device in systemd is held up by something else?18:12
xnoxtkamppeter, no idea. Laney's printer unplugs just fine....18:27
xnoxmost devices do too....18:27
tkamppeterxnox, I have reduced the ippusbxd problem onto the unplug problem now. If I plug the printer after a daemon-reload, it reliably starts the ippusbxd service, even without ExecStartPre delay, independent of forking or non-forking ippusbxd and also with presence of the 70-printers.udev rule.18:35
tkamppeterxnox, perhaps it has to do with the fact that it is an MF device with scanner.18:37
tkamppeterxnox, or a device supported by HPLIP.18:37
tkamppeterxnox, is there actually some way to see whether a device like sys-devices-pci0000:00-0000:00:14.0-usb2-2\x2d1.device in systemd is held up by something else?18:38
xnoxtkamppeter, it's not a systemd question. it's a kernel question. try #ubuntu-kernel18:41
tkamppeterxnox, the removal of the device also does not take place when removing HPLIP, so HPLIP is also not the cause.18:47
tkamppeterxnox, sorry, I had some problems to get into the #ubuntu-kernel channel, but now I am in and asking there.19:06
