Ardour8 still chasing "find a trout" in Debian12 - logging? stereo channels? unattended install?

OConnorStP · October 12, 2023, 7:53pm

Shmitty – yep, Ardour runs if i manually start Jack. the reason i’m burrowing into this is because it’s a nice repeatable error which, when solved, may help identify other less-visible problems.

Robin – thanks for the invite to IRC. i’ll save that for a day when i need fast turnaround, however this isn’t that urgent. also thanks for the refinement of gdb. i ran with those this morning and here’s the change. meaningful, or just an artifact of how Ardour bails out when the Trout has been invoked?

Find a trout and repeatedly slap the nearest C++ who throws exceptions without catching them.
Ardour will likely crash now, giving you time to get the trout.

Thread 1 “ArdourGUI” hit Catchpoint 2 (exception thrown), 0x00007ffff54a90a1 in __cxa_throw () from /lib/x86_64-linux-gnu/libstdc++.so.6

(gdb) continue

Continuing.
audio-midi engine setup failed.

i noticed that i can return Ardour to normal startup by deleting the config file. all the 1st runs i could figure out to try after doing this result in Ardour not starting Jack on the 2nd run. but at least i don’t have to stand up a new server each time to test. maybe that’s a clue? here are examples of the things i tried:

substitute the AudioMIDISetup section from the Ardour6 config file
try various templates
try closing without saving
try adding an audio track and changing Audio/Midi Setup

here’s a link to a typical config after a 1st run where i’ve set Audio to Jack, Dummy, Default, 48k, 512 and Midi to none.

hi Paul,

ah! thanks! here’s the new stuff. the weird purple blobs are the forum software treating the double-colons around : : Thread: : as formatting…

OK, next up please get a debug build from https://nightly.ardour.org/ (there are free/demo copies; you can install them in parallel with whatever you already have), and repeat those steps.

OConnorStP · October 12, 2023, 9:35pm

will do. but it’ll be tomorrow before i can get back to this. thanks!

So:

just before this happens, is it possible to see what the buffer size selector says?
the nightly build tomorrow will have some more debugging info being shown to track down what is going on here, so give it at try at about 10:00 UTC or later.

OConnorStP · October 13, 2023, 12:30pm

here’s the terminal transcript from the run this morning. fingers crossed the that buffer-size into is included. if not, let me know how i can get it for you.

btw, i’ve broken the transcript with a line feeds just before each of my gdb commands. they’re a mix of the debugging web page, Robin’s suggestions and your suggestions. so i may well be Doing This Wrong.

Does moving ~/.config/ardour8/ away help?

Make a backup (e.g. mv ~/.config/ardour8 ~/.config/ardour8.bak) , so in case it does, we can investigate; or you can restore it in case it makes no differences.

OConnorStP · October 13, 2023, 12:47pm

ah! i was hunting around for the config file in /opt.

yes – moving it out of the way now has the program running. it’s on the Session Setup page now. is there anything useful i can do in gdb at this point?

x42 · October 13, 2023, 12:49pm

No but please upload the old ~/.config/ardour8.bak/config file.
I suspect it contains some old invalid Engine state, which causes this.

here’s a link to a variety-pack. you will see two from my ardour7 testing yesterday and the one that was moved aside this morning

btw – i can give you credentials to this server if you’d like to tinker with it directly. it’s a throw-away, i can rebuild it in 10 minutes if you break it.

@OConnorStP said:

I have the feeling there’s more-detailed logging available – but I can’t figure out where it is.

I too use Debian 12, but on my local computer with XFCE4 desktop. I use the PipeWire from the Debian package and run the Ardour package with prefix ‘pw-jack’. The other suggestion in documentation under /usr/share/doc/pipewire about dynamic linking of shared object (so) code did not work for me.
zcat /usr/share/doc/pipewire/README.Debian.gz
It caused package-installed Ardour 7 to not be able to control connections, and I love the green dot matrices, better than a graph application. You can read about my failed PipeWire upgrade attempt without a system install at My Newbie Perspective on Ardour 7.3.0 on Debian 12 with PipeWire , which is probably not very useful.

What might be useful on Debian 12 only is to run:
cat /log/var/README

By default all logging in Debian 12 is by systemd and accessed with the command-line command ‘journalctl’. You could put everything into the less pager (journalctl | less) and use the forward slash search feature. It is not clear to me how some of the filtering options work. In particular, this option combination is not very useful for me:
journalctl --user _SYSTEMD_UNIT=pipewire.service
whereas this is more useful to me (and seems to get a superset of results):
journalctl --user --unit=pipewire.service

You could try this (last option is optional for this usage):
journalctl --user --priority=2 --grep=ardour --no-pager [--output=verbose]

Good luck. I’m not a real programmer.

Abyss – good tip! i hadn’t realized until now that a lot of the logging has moved over to journalctl. i just spent some time driving around in there. unfortunately i didn’t find any clues, but the searching was fun. thanks!

OConnorStP · October 14, 2023, 12:26pm

i’m in a hurry, have to jump in the car and head out Real Soon Now… making lots of mistakes, but here is a text file with a few config files and a term session of the Ardour8 overnight. don’t have time to look at the config files. back Sunday afternoon.

1st run – under --gdb

I ran 8.0.36 this morning and couldn’t complete the 1st run under --gdb. i’ve attached a screen-grab of a little bit of the endless (seemingly looping but perhaps just probing a whole lot of stuff?) session. i let it run for about 5 minutes before killing the window.

ctl-C didn’t shut it down, so i don’t have a term-session of that run. but i did grab a mid-flight config file while the program was waiting for me at the Session Setup screen.

reinstalled it and didn’t import the plugins

since this seemed to be failing during plugin-verification, but it behaved the same way.

2nd run – straight from launcher - without gdb

it opened and i could load an empty session – however it didn’t ask for Audio Setup. there was an error in the log – “Patch without patch name list - patchfile ignored”

checked Audio Midi Setup, settings were correct (Dummy) and Jack was running. captured a 2nd-run config file.

3rd run – crashed from launcher - reran under gdb

captured a term session for the 3rd run and a config file at the end of the 3rd run

here is supporting stuff:

OConnorStP · October 22, 2023, 1:09pm

hi folks,

this one seems to have gone quiet. am i the cause? my apologies if i’m Doing This Wrong.

x42 · October 22, 2023, 6:04pm

All the config files that you have posted on dropbox and are identical and none contains an EngineState. Yet the backtrace shows that this can’t be true.

I still have no idea how this can happen and why it is only an issue on your system, otherwise I would have replied earlier.

The forum is not a great place to keep track of issues, would you mind filing a bug report at tracker.ardour.org and attach the only last config file ~/.config/ardour8/config that is currently present? Thanks in advance.

OConnorStP · October 23, 2023, 11:37am

Hi Robin,

yeah, the lack of EngineState popped in with the 8.0.36 release – i thought that was odd as well.

these systems are just Debian12 virtual servers on Linode. i build a new one from scratch every time i run a test for you, so i think this is likely something that is happening to other Deb12 users too. the nice thing is that this is easy to replicate.

thanks for the pointer to the bug-tracker. i’ll summarize this thread over there. it’ll probably be a day or two…
