All m4a files are listed as incomplete and unlinked on OSX about pianobarfly HOT 36 CLOSED

I am getting the same issues. I've applied hunner's patch in both fly_id3.c and fly_mp3.c. I'm getting the bus error, then the program exits.

from pianobarfly.

I committed a change (b8572bc) earlier tonight that may fix your problem. I replace the whole dirname() thing with tmpnam(). I've compiled it on Linux and FreeBSD but I don't have access to OSX. Give it a try and let me know if it doesn't work.

from pianobarfly.

I tried the changes in b8572bc and the files still get unlinked. I also tried using the changes in 928b65c but that did the same thing.

from pianobarfly.

With trunk, I can't reproduce this on Snow Leopard.

from pianobarfly.

nega0 - is this your modification of trunk? Which trunk? What version of XCode did you use to compile? There are a number of known issues with compiling this project with the version of XCode that ships with Snow Leopard. How did you fix the dirname() issue? Which issue are you unable to reproduce - the "Error opening the temporary file" or the "Bus error: 10?"

from pianobarfly.

I used a fresh checkout of https://github.com/ghuntley/pianobarfly and the only change I made (besides to the Makefile) was to add a strndup() since Snow Leopard lacks its own. Everything worked as expected. There was no dirname() issue becaue dirname() was replaced in b8572bc. I also had no Bus error or errors with the temporary file.

Also using XCode 3.2.6

You can see my minor changes here

Also I compiled with: CC=gcc CFLAGS="-std=c99 -O2 -DNDEBUG" make

from pianobarfly.

Ok, so I tried that but was unsuccessful so far. That being said the protocol change has to go through for this to even work anymore. Do you (nega0) have changes that include the update to fix this issue as well as #22 ? If I use https://github.com/nega0/pianobarfly/tree/protocol_update the stream works, but we are back to every file being deleted. I also tried the nega branch, but that does not compile for me (at least right now).

from pianobarfly.

You could try merging my protocol_update and mkstemp branches.
Actually, I did it for you. You can pull my filtered branch.

from pianobarfly.

I tried the filtered branch, but I am getting the Bus Error: 10 again, and then the program exits.

Occasionally it will not throw the bus error, but the file does get unlinked.

I wonder if it has something to do with Lion or XCode 4.2.1

from pianobarfly.

Unfortunatly, I can reproduce each error on Lion (bus error, and incomplete/unlink) but not consistently. I was able to trigger the bus error under gdb. It occurred during the recursive call to _BarFlyMp4AtomRender() (fly_mp4.c:773). A call to _BarFlyMp4LongRender() (fly_mp4.c:705) couldn't happen because it couldn't access "buffer". "Can't access memory at address 0xXXXXXXXXX".

Got it to crash again with a printf(atom->name) at the beginning of _BarFlyMp4AtomRender():

It seems to have recovered and successfully tagged though. Hmm...

from pianobarfly.

I recreated our old develop branch and committed up a change that will hopefully fix this once and for all (267c0b1). I honestly don't know what I was thinking about the hole dirname() and tmpnam() stuff. If you look at the way the code works the tmp file can just be created in the root of the current working directory, which is always the base directory where files are being written. So basically this change just creates the tmp file in that directory and then move it to the final destination.

Give the fix a try and let me know what you think.

OS X 10.7.3
tried master and develop branches

compiled with make clean && make CFLAGS="-O2 -DNDEBUG -W6
4" DISABLE_ID3TAG=1

both giving me Bus error: 10:43 and exits consistently after first song.

from pianobarfly.

This is still an issue with the current commit and on OS X 10.8.2.

from pianobarfly.

still an issue with 10.7.5 as well.

from pianobarfly.

Is this still an issue?

from pianobarfly.

I still get a bus error.

osx 10.8.4 now.

from pianobarfly.

On OSX 10.9 DP4 w/ the current XCode preview, I'm not getting the bus error, but I am seeing the unlink issue. I'm only about 10 songs in though

from pianobarfly.

What build options did you use? and how did you install the rest of the dependencies? I used brew install to install pianobar first to get most of the dependencies..

from pianobarfly.

I put a basic page up on the wiki

from pianobarfly.

re-installed all the packages following your basic guidelines, then rebuilt pianobarfly using your command-line and i'm still getting the bus error. :(

I'm happy to help debug if there's any additional info that might help.

from pianobarfly.

The following patch will work around the unlink issue on OSX

Anyone who's seeing this bus error, I need some info. Make sure your sources are up-to-date, run pianobarfly, and let it crash. You should have (part) of the tmpfile in your "mp3 directory" (by default, ./mp3). It should be 394 bytes. The easiest way to do this is to run xxd pianobarfly-08VLkR | pbcopy and then Cmd-V in the comment text area. (Your tmpfile name will obviously be different.) You'll then get a block like this:

This will let me know if it's crapping out in the same place for everyone.

from pianobarfly.

On the unlink issue, WaitressPollRead() is somehow fucked on OSX. This line is erroring with a Connection reset by peer. I'm guessing we're trying to read more than the content-length, and we're getting to told to GTFO. Anyway, this then sets WAITRESS_RET_READ_ERR which trickles back up to here, causing us to to request data from after the last byte of the content-length, the server sends back an HTTP 400 (Bad Request), libwaitress/waitress.c freaks out because it doesn't know what to do with a 400, and we delete the file.

This is probably easily fixed by making sure we don't try to request a range greater than the content-length, but I want to know what's triggering the Connection reset by peer, and why only on OSX.

This all masks the SIGBUS error (because the file never gets tagged)...

from pianobarfly.

@nega0, swapped out laptops, need to get my environment all setup again and then I can get you some data. do you want me to apply the patch before collecting data?

from pianobarfly.

btw, on your wiki, you mention installing "faad", which I don't see as an available brew package.

from pianobarfly.

I didn't apply the patch, but I built the most current sources pulled down from github.

@nega0, hot! I'll give it a shot shortly.

from pianobarfly.

No such luck.. it's no longer getting a bus error, but it's still deleting "partially recorded file"

from pianobarfly.

add the patch in #15 (comment)

that'll work around it until i figure out what the real issue is and fix that

from pianobarfly.

OK, trying now :) thanks for all your work on this!

from pianobarfly.

So there's no bus error and it's not saying "deleting partially recorded file", but files and the associated subdirectories aren't being written to the mp3 directory.

from pianobarfly.

where's your mp3 directory and how are you running pianobarfly?

For instance, im running in it in the source directory using the default mp3 directory of "./mp3". So, I end up with

[badtz:~/pianobarfly] ./pianobarfly
[badtz:~/pianobarfly] ls
COPYING      ChangeLog    INSTALL      LICENSE      Makefile     README       contrib/     mp3/         pianobarfly* src/
[badtz:~/pianobarfly] find mp3
mp3
mp3/Autolux
mp3/Autolux/Future_Perfect
mp3/Autolux/Future_Perfect/Autolux-Plantlife.m4a

from pianobarfly.

ugh, sorry.. i realized I reverted back to a stock config file just to make sure my old config file wasn't causing problems.. it was placing them in ./mp3 just like you said. The files are there :)

Great work! Please let me know if I can help with debugging anything else or testing a fix.
