"20190713" of cource

I'm building the latest qjackctl package in OBS home:tiwai:branches:multimedia:apps/qjackctl repo.  Could you try later whether it addresses the problem?

If the problem persists with the latest package, it's more about jack package, not qjackctl...

it's still pending for rebuild
but I think You are right, that problem is in (lib)jack indeed

Just confirming that issue seems to be in jackd or libjack itself starting in the 20190713 snapshot. I have similar issues with or without qjackctl.

Jackd seems to start OK, but any client trying to connect segfaults. The partial gdb trace below shows from jackd server side. The first "Broken pipe" is from when "a2jmidid" trys to connect, the second two are from when "hydrogen" tries to connect.

Let me know if can help isolate this. Thanks:

Can we start by installing libjack0, jack, qjackctl and hydrogen from:
https://download.opensuse.org/repositories/home:/plater/Tumbleweed

Hi Dave,

I added your repo and went ahead and updated the following packages to your version:

- jack
- libjack0
- libjack0-32bit
- libjacknet0
- libjackserver0
- mpg123-jack
- pulseaudio-module-jack
- qjackctl
- qjackqtl-lang
- hydrogen
- libhydrogen-core1

I'm not seeing a change in behavior. One note is that I normally have qjackctl use the DBus interface which will then load/unload the pulseaudio sinks as needed. However, I found that when the pulseaudio sinks are loaded it blows my entire audio system out of the water (no cards found until reboot). So I tried to comment out the lines in /etc/pulse/default.pa that load the sinks. This keeps my audio from blowing up, but all jack clients still segfault.

It doesn't seem to matter if using jackd or through jackdbus, the server will start, but as soon as it any client connects (qjackctl, a2jmidid, hydrogen) the client segfaults. The server reports a broken pipe, but keeps running.

Thinking it might be linkage to alsa or pulseaudio, I removed ~/.config/rncbc.org/QjackCtl.org and tried new config using other audio drivers. Even with the "dummy" driver, as soon as I start jackd/jackdbus from qjackctl, qjackctl segfaults. The server does continue to run as a daemon, but any connecting client also segfaults.

FWIW, I use the computer for multiple things, but one is creating music with jack and Ardour. I know that Tumbleweed is probably not the stablest audio distribution, but I've had good luck (and stability) with this setup for many years and my hardware configuration hasn't changed. I don't know if this is somehow related to the recent LTO build changes (don't know if any of these packages have it enabled/disabled).

Also, I didn't understand Konstantin's comment:

temporary switched jack and jacklib0 to 1.9.12~git20190619T124043-159 from home:X0F

Did that mean that fixed the issue for him? I went to https://build.opensuse.org/project/show/home:X0F, but don't even see those packages listed, but I may be missing something.

Anyway, thanks for helping me with this.

Carl

sorry, I was too hurry when reported this
right repo is:
home:X0F:branches:multimedia (https://download.opensuse.org/repositories/home:/X0F:/branches:/multimedia/openSUSE_Tumbleweed/)

gcc started building with Link time optimization on the date that this bug was created so as a start I've disabled lto in the build and libjack0-1.9.12-111.1
from home:plater is built without it.
I can confirm that Tumbleweed jack from the latest snapshot crashes zynaddsubfx but when built without LTO it doesn't.
I first tried simply changing libjack0 but I had to update jack as well.
Please test and confirm, I'm going to submit jack to Factory anyway.

I can help you with debugging of the jack issue. Do we have an easy reproducer?

Very easy install zynaddsubfx from Tumbleweed, that's what I used to reproduce and run it from the console. If you haven't got jack installed, it will be pulled in.
I'm not sure if this issue is fixed in their latest git, I had a look but couldn't see anything relating to it. I've sent sr#718138 to Factory with LTO disabled.

The fixed jack is in:
https://download.opensuse.org/repositories/home:/plater/Tumbleweed

The error I get from zynaddsubfx is:

Works fine when jack is built without LTO.

Well, I would like to understand the issue. LTO disablement is only papering over the issue..

I did a zypper dup prior to testing jack via zynaddsubfx maybe that's why you get a different result.
The binaries involved are jack, libjack0, libjacknet0 and libjackserver0

I did so, but I can't see the segmentation fault :/

I can reproduce this by "zypper in -f jack libjack*" after disabling my home repo, this installs the debug packages as well (I've removed the normal start up text and only included the different text):

Does this help you to pinpoint the problem?
The jack in my home repo won't crash.

I've just done the same, I don't have any extra repository, but I can't reproduce that. Let me test it in a KVM..

The hardware I use for Tumbleweed is mid 2018 HP pavilion with an i3 and 4G ram.

At this point something goes wrong on your machine and jack quits, this is what normally happens:
configuring for 48000Hz, period = 1024 frames (21.3 ms), buffer = 2 periods
ALSA: final selected sample format for playback: 32bit integer little-endian
ALSA: use 2 periods for playback
Cannot use real-time scheduling (RR/10)(1: Operation not permitted)
AcquireSelfRealTime error

Then at this point jack crashes.
@tiwai
Can you shed some light on what's going wrong here with Martain's alsa?

Maybe the device is already being used by some others (like PulseAudio)?
If you're running PulseAudio, start the program with pasuspender to make sure PA leaves the devices.

just run jack with dummy driver:

jackd -d dummy

then any jack_client will crash:

And I agree with Martin, simple playing with LTO is not "our way".
Is there the objections to providing updated version from git?

Sorry so long to get back. Just got back from work and checked emails.

Thanks Konstantin for details on repo and agree that can troubleshoot with "dummy" driver to decouple any audio system linkage.

Thanks Dave for non-LTO builds. Can confirm the ".114" builds fixed the issue for me. Sounds like would like to narrow down further and make work with LTO enabled.

Let me know if have other packages would like me to test. Thanks to everyone for quickly isolating this.

(In reply to Konstantin Voinov from comment #24)

Because jack is used by many packages I prefer not to use git especially the development branch used by XOL. If someone can locate the commit that fixes the LTO issue I will use a patch otherwise jack works fine when built without LTO and I'm sure that the space saving is minimal.
This isn't papering over an error it is building jack in a way that it works.
I don't think that using git is warranted.

I can't get a crash from plain "jackd -d dummy" only in fact I can't reproduce your crash using "jackd -d alsa" either.

Can you please show me the output of "zypper se -si jack"

Great, I can reproduce it now and I'm going to debug that..

Ok, so the client segfaults here:

which is a string manipulation function. I bet it's related to warnings seen in the package:
-Wformat-truncation=

I would recommend fixing all these warnings first.

Well, the list of warnings is pretty long for the project:

>>Because jack is used by many packages I prefer not to use git especially the development branch used by XOL. If someone can locate the commit that fixes the LTO issue I will use a patch otherwise jack works fine when built without LTO and I'm sure that the space saving is minimal.
This isn't papering over an error it is building jack in a way that it works.
I don't think that using git is warranted.


1.9.12 is quite old. What is TW's policy for providing not-stable versions of apps and libs, should them be tested for a while by members or whatever?

kxstudio uses 1.9.12+git20190321 for example

There is no pressing reason to use git, a new release is due soon. Is there a particular feature that you want?

If anyone wishes to test git they can install from:
https://download.opensuse.org/repositories/home:/plater:/jack/Tumbleweed

*** Bug 1142877 has been marked as a duplicate of this bug. ***

I'm not sure where the idea that this bug is fixed in jack git, it crashes in the same way when built with LTO

Today updated 32-bit version of Tubmbleweed in my virtual environment (VirtualBox). Can confirm that Jackd and QJackCtl are crashing.

Installed source RPM of jack, added '-fno-lto' to the compiler flags:

export CFLAGS="%{optflags} -fno-lto -ggdb -fPIC"

Then rebuild with rpmbuild and installed RPM packages.
Jack started well and works just fine.

fixed 32 bit jack is available in my home repo and multimedia:libs until it reaches Factory

The macro disabling LTO has been silently removed from the spec file a while ago and no one has experienced any bad effects so I'm closing this as fixed.
