QjackCtl 0.3.6 - Full D-Busification!

9 March, 2010 - 19:00 — rncbc

Awe! Times they are a-changing although Bob Dylan has no D-Business here. The old and cutie gooey for JACK just got one turn around the verge of bit-rotting. This time it brings full JACK D-Bus support, or almost. It also adds D-Bus access for most GUI actions which some might find pretty handy for keyboard shortcut binding from your desktop environment of choice. However, if babies health is your top concern you can just turn this D-Bus thing off and play with the Old times ;) Ahem...

QjackCtl 0.3.6 is now released!

More details in the change-log, below.

    Change-log:

  • Make sure socket names are unique on each side of the Patchbay (another patch from Dominic Sacre, thanks).
  • A bunch of primitive D-Bus interface slots have been added, allowing shortcut access to most of main applications actions like toggling Messages, Status, Connections, Patchbay widget pop-ups, reset stats, transport and so on. New bindings are given eg. via dbus-send --system / org.rncbc.qjackctl.(main, messages, status, connections, patchbay, setup, about, reset, rewind, backward, play, pause, forward). (from an original idea from Sebastian Gutsfeld, thanks).
  • Patchbay snapshot now tolerates JACK client port strings that have more than one semi-colon in it, honoring just the first one exactly as everywhere else eg. Connections. (a glitch as reported by Geoff Beasley while using a2jmidid).
  • Most modal message dialog boxes (eg. critical errors) are now replaced by system tray icon bubble messages where available (mitigating feature request #2936455).
  • Comply with jackd >= 0.118.0 which now runs in real-time mode by default; use of -R is now deprecated from the jackd command line interface options; use -r to run in non-real-time-scheduling.
  • A man page has beed added.
  • Got rid of a pretty old and never really useful "jackd-realtime" server path option--actually, it was only seen available on the now defunct old Mandrake Linux distro.
  • D-Bus support, as provided by org.jackaudio.service aka jackdbus, is now being introduced and used wherever available and whenever enabled. Configuring, starting, stopping and logging the JACK back-end server through the "infamous" jackdbus service is now being seamlessly exploited.
  • Global configuration state is now explicitly saved/committed to disk when Setup dialog changes are accepted and applied.
  • Server name command line option added (-n, --server-name).
  • Single application instance restriction option added (X11).
  • Setup for the netjack (slave) "net" driver has now sample-rate and frames per buffer (period size) settings disabled and/or ignored, as those are pretty much auto-detected by default; also, a new "netone" backend driver option has been introduced (as suggested by Torben Hohn).
  • Czech (cs) translation added (by Pavel Fric).
  • Fixed some main window keyboard shortcuts. Escape key now closes Connections, Patchbay, Status and Messages widgets as usual (bug #2871548).
  • Fixed glitch on configure portaudio support, specially when the library is not detected as available.

    • Cheers && Enjoy.

    Ok, with log feature I discovered one interesting thing...
    Quitting the application, qjackctl executes a pre-shutdown script before jackd stop, and a pre-shutdown script after too!! I don't know if this issue is only on qjackctl from debian sid.
    Using start/stop from gui, every script works well.

    I'm also doing italian translation for the gui, could you include it?

    Thank you

    Now, are you sure that "Post-shutdown scripts..." is never seen on the logs when you quit? You say that "Shutdown script..." which is about the pre-shutdown one, appear twice?? Weird.

    Re. regarding (it) translation, you're welcome! Send me your "qjackctl_it.ts" file in a email attachment and I'll be pleased to add it to the source code repository ASAP.

    Yes, as you describe I've 2 pre-shutdown scripts in the log:

    22:22:42.103 Statistics reset.
    22:22:46.227 Client deactivated.

    As you can see, pulse-into-jack pre-stop is executed twice.
    Here's an extract from my Qjack.conf:

    [Options]
    StartJack=true
    StartupScript=true
    StartupScriptShell=pulse-into-jack pre-start
    PostStartupScript=true
    PostStartupScriptShell=pulse-into-jack post-start
    ShutdownScript=true
    ShutdownScriptShell=pulse-into-jack pre-stop
    PostShutdownScript=true
    PostShutdownScriptShell=pulse-into-jack post-stop
    StdoutCapture=true

    I don't know if this problem is debian related.

    My translation isn't finished yet. I'll send you as soon as I complete it! I think in a few of days..

    May you try with your pre-shutdown script in stub mode, that is doing nothing but printing its invocation mode ?

    I suspect you're bringing the jackd server down with pulseaudio, while on the pre-stop case and that just sounds like a race condition is lurking in there, as qjackctl will try to terminate jackd once again, right after the pre-shutdown script returns.

    Seeya

    24 March, 2010 - 12:30 — rEvol (not verified)

    I think no, jackd is not killed by pre-stop script.
    Here's a log of a simple start and stop using the gui buttons:

    Everything works well doing start/stop.

    The problem is when I start and quit the app, behaviour that can be seen on my previous post.
    What do you mean with "stub"? Something like "execute the scripts separately in a shell"?

    Thank you

    P.S.: this captcha is driving me crazy!! too difficult!!

    Re. What do you mean with "stub"?
    erm, just printing a "post-stop" line would be fine, but don't take any other actions besides that.

    Re. captcha is driving me crazy
    if you register you'll get rid of the captcha :) even with that crazyness there's spam sneaking in, so i won't make it any easier :) sorry.

    [UPDATE] Would you mind checking out from current SVN TRUNK (qjackctl 0.3.6.1+) and test whether things are any different?

    Cheers

    you need to create the configure script, following the instructions:

    make -f Makefile.svn
