Routing doesn't work with sources/destinations contain utf-8 symbols

[ChihHao-Su]

Target version
MusE 4.1 Flatpak

Describe the bug

• In the destinations and sources diagram (the upper part of the dialog), all non-latin charaters turn into ?.
  

• Click a row in the distinations and sources table (the lower part of the dialog), MusE cannot show the corresponding distinations and sources linkage on the destinations and sources diagram.
  

Expected behavior

• Non-latin characters show normally.
• Linkage of destinations and sources contain utf-8 symbols works normally.

Desktop (please complete the following information):

• OS: Fedora 37
• Desktop: Gnome

Hello. My initial tests:

The good news is that non-UTF8 characters seem to be working OK. Save and load are OK.
I was worried that it might be broken.

(Hm, the lines are supposed to be different colours. Broken drawing?)

In the screenshot, I do not have any Jack Audio terminals with non-UTF8 characters
like your screenshot. So I could only test renaming a couple of tracks to non-UTF8 characters.
I must see if I can tell Jack to rename some ports to non-UTF8 characters so I can test that part.
Maybe the Jack Meta system will help.

Therefore I must suspect that there might be a bug in our specific code section(s)
that work with Jack port names, such that by the time the router displays the names
in the 'Jack' source/destination sections, they are mangled.
Because so far some of the other router source/destination types seem OK.

In the screenshot, even though I am in an en-US locale, I am temporarily using
a French c locale and application locale for testing some other locale bugs.
So this bug report comes at an interesting coincidental time.

[ChihHao-Su]

My system locale is zh_TW.UTF-8, shouldn't the broken jack port name (shown in my screenshot) be UTF-8?

Sorry I was probably confusing terms.
Wide characters is probably what I should have said.
There is likely a bug with wide characters specifically in the router dialog's source/destination lists code.
Clearly they are working in the lower connection list but not the upper lists.

[terminator356]

I did a test. I added some wide characters to the upstream routes Jack audio port names.
In other words, it is as if my audio device has Jack ports with wide character names, just like yours.
I could not reproduce the problem, as shown:

Can you do some more checks for me? I need to know if other routing items are working for you.
Please do what I did in my first screenshot:
Create a Wave track and rename the track so it contains wide characters.
(I use the KCharSelect character selection utility which lets me paste wide characters into text.)
Maybe try creating a few more tracks just like that. Midi track, Group track etc.

Then, open the router and see what happens.
Are all the wide character names of those tracks displaying properly?

Thanks.

[ChihHao-Su]

OK, I have created some track contain wide characters:

In the router, these tracks look fine.

The jack ports contain wide characters cannot display properly.

[ChihHao-Su]

I tried the latest AppImage release (4.1), the problem still exits.

[ChihHao-Su]

When I open the router, I found the console shows:

'o != NULL' failed at ../pipewire-jack/src/pipewire-jack.c:4695 jack_port_name()

I don't know is that related to this issue.

Thanks very much for the tests.
Hm, that pipewire output looks suspicious, especially since it happens when you open the router.

I looked very deep into the router source code yesterday.
The missing connection lines are a big clue.
These lines do not depend on the text being correct, they simply depend on the
routes being there. Clearly the bottom list is able to show the routes do exist,
but not the connection lines. This suggests invalid Jack ports, rather than incorrect text.

Are you able to build from github master source?
If I push a few debugging output lines into the code base just for you, are you able to test?
(This would be the next best thing to me being there - remote debugging!
Apps like Team Viewer also come to mind.)

[ChihHao-Su]

Are you able to build from github master source?

Sure, I can try building form source after I get off my work.

If I push a few debugging output lines into the code base just for you, are you able to test?

I think yes, if I can compile MusE successfully. I think we can try this first. If things get complicated and you need to debug on my machine, I can allow you to remote control my PC for a period of time.

Thanks.
I am just finishing some other work, I will push the tests later and inform when ready.

Hello @ChihHao-Su Sorry for the long delay.

I have reproduced the problem. And I have found the trouble.
And I have just pushed a fix in github master.

Changed all QString::toLatin1()/tolocal8Bit() usages to QString::toUtf8() in the following files so far:
jack.cpp, jackmidi.cpp, route.cpp.
TODO: CHECK: Likely (many) more to do, EXCEPT some parts like xml, where we want SOME latin1 compatibility.

Try it and let me know if any more trouble.
I expect there may be more troubles.
We have many places still using QString::toLatin1()
I am investigating...

Hope that helps with the issue so far. Good luck.

Hi,

It seems that things get worse after pulling the master branch. When I startup muse4, I got:

There's a lot of "jack connect <xxxxx> - <yyyyyy> failed with err:22" which are abnormal, others are just fine.

And, I cannot connect ANYTHING in muse to jack ports in muse4. For example, I have:

But the graph in qjackctl shows:

Now the only way to get output of muse form my device / get input in muse form my device is to connect them in qjackctl manually.

Hi @ChihHao-Su .
I have been studying your posted results for a few days now.
I am very puzzled about what's going on here.

I need to ask: Do you recall, about the text that was posted (the text with all the error 22),
is this text the the actual output from the same session as the two pictures posted below the text?
Or is the text from a different session than the one from the two pictures?

I am asking because there is something strange about the text vs. pictures.
The text indicates PipeWire is altering MusE's Jack client name:
It says "pw-MusE". (It is OK, it is allowed to do that).
For example the "<pw-MusE:Out 1-0>" etc.
But in the two pictures MusE's Jack client name is just "MusE".
This could not be possible, I think.
Please clarify.

About the textual jack connect errors:

We usually see error 17 (it is normal and means the connection already exists).
But we do not usually see error 22. Error 22 means "invalid argument".
This means one or more of the three arguments passed to Jack's jack_connect() function is invalid.
They are: The client pointer, the source port name text, and the destination port name text.
But from the textual error output everything seems OK.
For example the source client is "pw-MusE" and the source name is "jack-midi-1_out", and the destination
client is Midi-Bridge and the destination name is "CASIO USB-MIDI 2:(playback_0) CASIO USB-MIDI MIDI 1".

Both "jack-midi-1_out" and "CASIO USB-MIDI 2:(playback_0) CASIO USB-MIDI MIDI 1" do exist
on your QJackCtl graph, in the second picture.
However, our client name is just "MusE" in the second picture.
It does not match the text.

So I am puzzled by this.
Can you verify and maybe post some more pictures and console text?
Please also use the -D command line option for more debugging output.
Also if you could take a few pictures with MusE's router showing "Normal", "Alias1", and "Alias2",
that would be good.

And last... what about the original issue, the utf8 characters? Is that working now?

Thanks for your help.

[ChihHao-Su]

Sorry for the super LONG delay due to something happened to my home town. After I came back, I did a full-system upgrade, I upgraded my system to Fedora 38, and it's pretty weird that the problem is gone, master branch works fine on my PC with UTF-8 jack devices, I can establish connections between tracks in muse and jack ports. I did nothing to my system configuration, hardware (include my midi devices). I think it might be some bug occurred by some packages were not up to date (mixing old and new packages) or just some problem in older version of Fedora.

Yes, the text and the image below are from the same session. That also confused me cause I cannot find "pw-SomeThing" anywhere. I have no idea about why it appears.
