Nature of xruns
I never paid attention to mentions of xruns since I rarely got
them using a stock Fedora 8 kernel (and F6 before that) on a
x86_64 architecture, 4GB RAM. Yesterday though, I got plenty of
them and my observation is that in this case any real-time
feature associated to the kernel does not matter. In this case
the xruns are made by the way applications handles
stuff (whatever that is). So that makes me think that there
ought to be a guideline, a best practices in developing Linux
audio/jack applications.
Here's the observation setup.
First, the song. The song does not matter, It always plays
fine. The song is made by the use of Seq24 which drives several
soundfonts loaded by Qsynth in different engine instances, as
well as two sounds made by Zyn. Qsynth has several instances of
FluidR3_GM (120MB) and one SGM (250MB) loaded.
Second, the xruns. I take the outputs and drive them through
jackmix, add electric guitar line-in from a Vox amp, and have the
outputs of jackmix feed into Qarecord. Start recording. The
.wav result is polluted with xruns.
Third, same song w/o xruns. I terminate jackmix and Qarecord
and launch Ardour. I run all outputs into Ardour, and run the
electric guitar as well. Add some Freeverb and MultiEQ. Record.
No xruns at all in the resulting .wav file.
From this it is obvious that the application layer helps a lot
in promoting xruns. It is safe to assume that Qarecord is a
quick hack. But, there's seemingly a big difference in
application design regarding the handling of audio/jack stuff
between Qarecord and Ardour since one produces a festival of
xruns and the other none.
My question is, is there a guide/HOWTO around that addresses
the proper design of audio/jack applications or, is - in 2009 -
the only to know about that is by actually going through the source
code of successful Linux audio/jack applications ?

As a non-lad I just say: It is not that bad.
As of 2009, there are some guidelines:
The 'JACK API Reference Manual' and
'Writing Audio Applications With JACK - A tutorial/journal'
are linked from here:

I don't know about Qarecord, but unfortunately JackMix is an example of
a JACK app that does not "follow the rules".

The rules are quite simple, but in many cases not exactly easy to
implement.
Inside the JACK process callback, you may not call anything that might
block, i.e. that might suspend the calling thread indefinitely. That
includes:
- memory allocations (and deallocations)
- waiting for mutexes etc.
- file IO, printing to the console, etc.
The main difficulty lies in the fact that these things are often hidden
deep inside some library code. So you should either verify that a
function is safe to use in realtime code, or avoid using it in this
context.
As for common solutions to these problems, the link to the previous
thread David posted should be a good start.

Such callbacks must be treated like, if I may make the analogy, the
bottom part of an ISR.

Yes. It is better to set context and return from such callbacks
as soon as possible. Then some kind of observer, free of such time
contraints, would react on the set context variables/structures.

Thanks to David also. I'll start reading the JACK API. Looks

But the main reason for the jack-thread is that processing there happens when
jack needs it and with the priority jacks needs while all the extra threads
(gui is one of them) have lower priority to not block the audio stuff. When you
do the audio creation in another thread and only push it to the jack-threads
ringbuffer, you have to make sure that buffer is always filled to not get gaps
(actual xruns but without jack complaining, only audio missing).
While this works when you "just" stream media from disk, this will not work
with samplers/synths/effects as these react to external signals that come in in
the same priority and should be processed as fast as possible instead of when
the to-jack-ringbuffer actually reaches that data...
If the sampler uses a separate thread (with lower priority), this would mean
that the midi-event comes in and the according tone is just generated and
appended to the ringbuffer. Some time in the future the ringbuffer would get
sent to jack. But you actually want the jack-thread to only interpolate the
events time inside its current audio-buffer and push the tone out as fast as
possible. Otherwise there would be no valid reason to tune the audio-latency
to low values for live-synths and effects...
A well behaved jack app is not one that does almost nothing inside the jack-
callback, its one that does what is necessary as fast as possible. That
implies not using certain operations such as new/delete/free/malloc but allows
for audio generation to be done inside the callback.
And especially this allows for the callback to process the incoming audio and
output it again in the very same call. (Which makes JackMix well-behaved:)
Otherwise mixing and effects would all add a delay you don't want.
Have fun,
Arnold

Zyn is squarely out of the problem domain since xruns can be had with
and without it, by changing other applications eg. switching from
jackmix/QARecord to Ardour).

In this particular case, I'd expect memory to be allocated for the
storage of the map elements, and probably for the content of the
QStrings (which are used as map keys) as well.
That said, I have no conclusive evidence to prove that any of the xruns
I've seen in the past were actually JackMix's fault. The real problem
might have been elsewhere.
I also use a lot of STL and various Boost libraries in my own JACK

as far as I understood your experiment, you compared these two setups to
conclude "QARecord is to blame":
1) noise -> jackmix -> QARecord -> wav-file
2) noise -> Ardour -> wav-file
For mathematical reasons I would like to get your result from this
alternative setup (also giving better access to a root cause):

This is because it was not much of an experiment to start with but
rather an observation derived from finding a way to record the song
without so many xruns.
As such, the observation was quite clear: kernel real-time
capabilities, although they might play a role somewhere, had nothing
to do in producing xruns since switching applications resolved the
problem. From that observation then a question arose: there must be a
bad way and a good way of writing a Linux audio/jack application: what

Indeed. That's the possibility I haven't explored since I think the
result of the observation was to see that there's a bad and good way of
writing such applications. Now, that the bad way lies with jackmix
and/or Qarecord is a second point that has more to do with technical
performance in the context of writing such an audio/jack application.
Which is not the case at the moment. I'm currently working on a project
that has nothing to do with such matters but I consider for a next
project to make a Linux jack application that would ease my music
making as I find there are some things that could make it easier to
make music.
Some other interesting information would be, what
program versions
(jackmix, QARecord) are you using?
Hmmm.. I'd disagree with this insofar as debugging these apps is
certainly not the matter.

Operating... Yep. Plug inputs into jackmix, plug jackmix outputs into
QARecord. Adjust levels. Ah, did I forgot to turn the computer on ?
Publish to find out ? Everything works well with Ardour, as I've
mentionned in the original post. So why bother with apps that I
just about never use and probably will never again ?

Yes sure, this is common audio programming standard.
But is it the
whole picture?
I'll see when I'll be doing an audio/jack app. Then I'll have
details. It could be that I'll never get details about what makes the
jackmix/QARecord fails. Could be. Will I be missing much ? I don't
think so.

Well, if the only way to go was with jackmix/QARecord then yes, a
solution should be found. But since the problem is easily solved by
simply using Ardour (I always use Ardour by the way and I've never used
jackmix before, and now, thinking about it, in the last two years,
recordings (few, near the beginning) with xruns were done when QARecord
was in the loop) then there's no need to look deeply in the
mechanics of jackmix/QARecord. If I want to look at some example code
I'll at least look up Ardour because it works well (or any other app
that I can try and works well).
Tschüß, und vielleicht bis später.

I'm pretty sure that the list server can be configured to put the
list's address in the Reply-To field. That way, there's no need for
MUA-specific tricks.
Just my 2 cents.

I use thunderbird, and I have two reply-buttons,
which works like this
with messages on lau:
"Reply" will send a reply to the author
only.
"Reply All" will send a reply to the
author + cc other authors + cc the
lau list.
yes and a simple "List-Reply" is missing since years (Bug #45715).
I asked before, and there doesn't seem be
anything to do about it in my
thunderbird setup). So someone (here, I think) suggested that I just
made a habit of using "Reply all" on all lists.
I do not use Thunderbird but "mutt"; here I can type "l" to activate
"List-Reply". Pretty simple, even works with cc-ed mail.
I just did some internet search for you and found this (possible)
solution:

I hope this helps; it is definitively worth a try.

Guidpo

you mean reply-to munging

I would not go that route.

After reading that article, I'm no so sure I would either...

I've ended up by configuring gmail to "reply to all" for everything.
Oh, and the link you post really assumes that everyone is using ELM. I
used that program in the 1980s ... I think this is 2010 :) Maybe I
need to put on my reverse-time-suit :)

If you've never received a potentially embarrassing personal email
inadvertently via a public mailing list, you clearly haven't been
around for as long as...
Hey -- hang on -- you've been around for ages!
Either you're very careful and you look away discreetly when other
people do weird things, or you've mostly been hanging out on lists
that don't do reply-to munging. Me, I don't really want to see
another "hey! how are you? I'm fine, just about to divorce so-and-so"
or "you guys really sold me out on that audio reseller deal"... No, I
really don't.
The arguments about convenience are mostly moot, you could argue
either side. The difference in seriousness of the most common "user
failure" case is the argument that surely matters most.

Shhh... you're giving away my age :)
But, seriously (as well) I think the biggest problem with all this is
that just about every mailing list I subscribe to uses a different
reply format. Some are like this one, others give a reply to the list
and the poster, and others are just a mystery.
And getting everyone to agree is probably not going to happen :)
So, probably best to leave well enough alone.
As far as getting/sending inappropriate mail .... naw, never happened to me :)

Problem solved for you, but not necessarily for the recipient. For
instance if you reply-all to this email, one of two things happens:
a) I get one email directly from you and none from the mailing
list. However, since it doesn't come from the list manager it
ends up in my inbox and not in my LAU folder. Bummer.
b) I get two copies, one directly from you in my inbox and the
other in my duplicates folder. Double bummer.
If its meant for the list send it only to the list. If its mean
for the person only send it only to that person.
