Liquidsoap freezes with some files - only when in daemon mode

mkonecny commented 11 years ago

The script:

path = "/home/martin/tmp"
set("log.file.path", string.concat([path, "hang.log"]))
set("server.telnet", true)
set("server.telnet.port", 1234)
set("init.daemon.pidfile.path", string.concat([path, "hang.pid"]))

queue = request.equeue(id="queue")
output.pulseaudio(fallible=true, queue)

The file: https://dl.dropbox.com/u/256410/airtime/rayj.mp3

Instructions:

Part 1: Run as regular process

Run

$ liquidsoap hang.liq

Telnet in and do

queue.push rayj.mp3

Notice music is playing.

Part 2: Run as daemon

Run

$ liquidsoap -d hang.liq

Telnet in and do

queue.push rayj.mp3

Liquidsoap process compiled from 36f750a is now frozen

toots commented 11 years ago

I can totally reproduce on a linux box.

toots commented 11 years ago

@smimram Can you reproduce? I think you know pulseaudio better than me, maybe you have an insight of the bug?

Also, @mkonecny, can you possibly use output.ao to mitigate the issue while we look for a fix?

Thanks y'all!

smimram commented 11 years ago

Here it's more fun. Without -d it works as expected. With -d I get:

$ ./liquidsoap -v -d hang.liq
environment reference count went negative

Never seen this one yet... but it's a good starting point for investigation...

smimram commented 11 years ago

However, sorry but Liquidsoap works as expected with -d here (apart from the above message)...

toots commented 11 years ago

Have you pushed the track through telnet after starting the daemon?

smimram commented 11 years ago

Yes...

toots commented 11 years ago

:poop:

smimram commented 11 years ago

Can't you have a stacktrace on your side ?

toots commented 11 years ago

Yeah, I'm gonna look at it very closely ASAP. I was hoping you could repro because my linux box is actually a virtual machine now..

mkonecny commented 11 years ago

Hey Romain, I don't think it's related to PulseAudio. I just made that output type for convenience purposes. It should crash with output.icecast as well. I'll verify this for you as soon as I can.

A dummy output would be even better! Le 4 avr. 2013 17:23, "Martin Konecny" notifications@github.com a écrit :

Confirmed that it hangs/freezes with output.dummy. I'm sure you guys are seeing this in non-daemon mode as output:

...
TagLib: String::prepare() - Unicode conversion error.
TagLib: String::prepare() - Unicode conversion error.
TagLib: String::prepare() - Unicode conversion error.
TagLib: String::prepare() - Unicode conversion error.
TagLib: String::prepare() - Unicode conversion error.
...

smimram commented 11 years ago

Not sure but it should not be a real problem. Could you please try to do the following while the liquidsoap process is hanged?

Find the PID of liquidsoap:

$ ps ux | grep liq
smimram  27092  0.7  0.3 1128876 31268 ?       Sl   19:23   0:00 ./liquidsoap -d hang.liq

(it's 27092 here).

Attach gdb to the process:

gdb --pid=27092

Show the stacktrace for all processes and send us the output:

(gdb) thread apply all bt

Samuel, I get a lot of output saying "no debugging symbols found". I'm sure I need to compile Liquidsoap with debugging enabled. but it looks like it is being compiled with the "-g" param???

ocamlc -c -cc "gcc" -ccopt "-fPIC -g -O2 -I.. -g -Wall -O3 \

Little confused here... Here's the output atm:

Hi @mkonecny

I believe that savonet/ocaml-taglib@4c28e5d should fix this issue. Could you please confirm?

Thanks!

mkonecny commented 11 years ago

Hey Romain, confirmed fixed! So the problem was taglib writing too much output which causes a deadlock? Interesting problem, still doesn't explain to me why it only happened in daemon mode. Is it because no tty reading the output buffer, it hangs when the output buffer is full???

toots commented 11 years ago

Great news! Honestly, the whole issue is a bit worrisome so I will try to keep an eye on it. The reason it appears in daemon mode and not in regular mode is this: https://github.com/savonet/liquidsoap/blob/master/src/tools/tutils.ml#L238 This a duppy tasks that reads data from stderr and stdout and redirects it to the proper logs.

This seems to conflict with ocaml-duppy writting a lot of data to stderr while having the OCaml runtime lock. Releasing the runtime before printing this data fixed that deadlock.

This is not satisfying tho as I do not understand why this deadlock happen. I looked at taglib's code and it is really simple:

void TagLib::debug(const String &s)
{
  std::cerr << "TagLib: " << s << std::endl;
}

Also, the deadlock does not happen if I write a small amount of data to stderr, like a single line.

Thus, it seems to me that we are still at risk of any other binding or similar C code spitting out a lot of data to stderr in daemon mode while holding the OCaml runtime lock.

@dbaelde, @smimram: do you have an idea on this?

smimram commented 11 years ago

No idea unfortunately... Anyway, most of the bindings are in blocking sections aren't they?

dbaelde commented 11 years ago

Nice catch! It makes it really crucial to make sure we release the OCaml runtime lock whenever something non-trivial happens. Like Sam says, this should already be the case, so this is not so bad and we may not need any radical change here... Otherwise the only ideas I have is (1) lame, but we may be able to increase stderr's buffer (2) heavier, re-route stderr like we do, but to a pipe to another process.. where the whole dtools logger would run :|

Hi,

I got similar error, but this time related to FLAC (should be open new ticket instead?)

I’m not running this in daemon mode, but I do have additional log in use in addition to stdout logging. I’m going to try this without the log now.

Hi! Thanks for the report.. Any chance you could attach a file and instructions to reproduce?

Smarre commented 11 years ago

It happens like after a day or so, I don’t know if it is related to exact file.

I’ll wait for few days to see whether it crashes without a log, then I’ll switch it back on and wait until it crashes and see whether I can produce it with a specific file.

My config is as following

set("log.file.path", "/tmp/liquidsoap-nyan.log")
set("log.stdout", true)
set("log.level", 4)
set("server.telnet", true)
set("audio.converter.samplerate.libsamplerate.quality","best")

enable_replaygain_metadata()

default = single("foobar.flac")

main = playlist("/music/dir")

        #request.queue(id="request"),
radio = fallback([
        main,
        default
])

radio = amplify(1., override="replay_gain", radio)

output.icecast(%vorbis.abr(bitrate=64),
    host="localhost", port=8000, password="funkysourcepassword", mount="lqnyan.ogg", radio)
output.icecast(%vorbis.abr(bitrate=320),
    host="localhost", port=8000, password="funkysourcepassword", mount="nyan.ogg", radio)
output.icecast(%ogg(%flac),
    host="localhost", port=8000, password="funkysourcepassword", mount="nyan.flac", radio)

Okay, I managed to reproduce this without the log.

Interestingly, when I put this track as single(), it doesn’t halt liquidsoap, but output it failed anyway. It seems to have started to actually play the track though.

This seems to only happen with FLACs. Need any other information? The track is copyrighted so I don’t think I could attach it here :P

smimram commented 11 years ago

Could you please send me the flac file on my mail smimram (at) gmail.com? Please use wetransfer or whatever if the file is big!

Smarre commented 11 years ago

Done.

To recap, this happens without log too, without daemon mode, and now it seems that without ”log.level 4” which I used to debug things. It’s always a flac that causes Liquidsoap to freeze.

Output without any logs is slightly different, so I’ll attach it here:

I’m starting to be out of ideas what to test :)

smimram commented 11 years ago

I did not get your flac file. I'd need it to reproduce... Does it always happen with a specific file? Any flac file?

smimram commented 11 years ago

Also, can you post the "minimized" script with which the error still occurs?

Smarre commented 11 years ago

It seems to happen with any flac file. The stranger thing is that sometimes the freeze is not triggered, I usually can get half day to day play time before anything happens.

I’ll test the most minimum script I can produce. I guess it just needs a flac in and nothing else is relevant.

I’m starting to suspect that it’s somehow related to my system. Otherwise it would happen to everyone... I have taglib-1.8 and FLAC-1.2.1. And ocaml-4.00.1.

Smarre commented 11 years ago

Oh and, I did sent a mail to your gmail address. Could you check your spam box? Might be that Gmail is hating me again.

Okay, yet another:

I'll try to have a look at the code. In the meatime, what version of liquidsoap are you using exactly? Did you compile from git, or is it packages? In the latest case, which distro and more importantly do you have ocaml-taglib 0.3.1?

Smarre commented 11 years ago

From git, few days old trunk. How can I find version of ocaml-taglib? If you refer the one from git tree, its revision is 03040e2330e4921db4b1e4fd638e8a703b0c2975

smimram commented 11 years ago

Ok, that's "fine" then (i.e. the old taglib is not the cause...)

From the ML, JD reported the following which seems to be related:

Sometimes when I do a call to the LS server via a unix socket connection I don't get any response from the LS server, and then attaching GDB to it I get this stack trace.

Can anyone maybe help interpret this stack trace?
