Scanning a large library directory causes crash #7287

Closed mixxxbot closed 2 years ago

mixxxbot commented 2 years ago

Reported by: jeffbuttars Date: 2014-01-30T19:26:01Z Status: Expired Importance: Critical Launchpad Issue: lp1274665 Attachments: [Size of each file in library](https://bugs.launchpad.net/bugs/1274665/+attachment/3964681/+files/Size of each file in library), [strace output Mixxx current git](https://bugs.launchpad.net/bugs/1274665/+attachment/3967824/+files/strace output Mixxx current git)

I've had issues while trying to scan a very large library directory. After some time of scanning, many hours, mixxx crashes. While re-trying a library rescan, after it had been scanning a few hours, I tried to open the 'Music Directory' dialog under the Library preferences and mixxx crashed.

On the console I got the message:

GLib-ERROR **: Creating pipes for GWakeup: Too many open files [1] 10396 trace trap (core dumped) mixxx

A quick search seemed to indicate a file descriptor leak.

OS: Linux, Arch Intel i7

Thanks for the report -- what version of Mixxx are you using?

Can you try mixxx-git from AUR (if you aren't already) to see if it repro's there?

Also, what file types typically make up your collection? MP3? FLAC? Ogg?

Is it possible you have a symlink loop in the folder you added that is making the scanner loop infinitely? Our scanner doesn't detect when it's in an infinite symlink loop.

How big is the folder you scanned? How many audio files and how large?

Version: 1.11.0

The files are a mix of various types. Mostly mp3 and many of the files copied from a mac. There some non-music files in there.

Total library size is 191GB

Breakdown by file created with:
find . -print0 | du -ha --files0-from=- > sizes.text
is attached

Symbolic links, none. Used this command:
ls -lR . | grep ^l
and got nothing

Number of files (not sorted or filtered): 
find . -type f | wc -
yields 32546

Using 
find . -type f | sed -n 's/..*\.//p' | sort -f | uniq -ic 
I get:

I re-ran the import and found that it's also leaking memory. I have 32GB of ram in my system and when I noticed issues in the system I found that Mixxx was using over 29GB of ram. Cancelling the import did not free the ram. I of course got the ram back after closing Mixxx

About myself using Mixxx: Not a DJ, primarily a software developer. Just messing around Mixxx and looking to use it for music replay for a podcast. I ran into the issue while trying to use Mixxx on my workstation to prototype a small studio setup. This is not my target library.

Thanks! Very useful.

What's your current file descriptor limit? (/proc/sys/fs/file-max)

Is there any chance I could get you to try and reproduce using our latest master (the mixxx-git package from AUR)? We've made a variety of changes to the library scanner over the past year. I can't remember a time that we weren't properly closing file handles but it's also a bunch faster than it used to be so I'd be curious to see how well it does on your library.

I installed mixxx-git from the AUR. When I start a library scan mixxx crashes after a few seconds. My guess the crash is unrelated to this bug.

When run under gdb and backtrace after the crash:

jeff:mixxx/ (master) $ gdb mixxx                                                                                                                                                                       [16:47:51]

Ok, that backtrace is super useful. It's clear the scanner has hit an infinite loop given it recurses 23k+ times :).

Looking at your directory structure, I don't see why that would be. As you said there are no symlinks and the deepest your tree goes is 7 directories (based on: cat sizes.text  | cut -f 2- | awk -F/ '{ print NF-1 " " $0; }' | sort -r -n )

Is it easy for you to transition from using mixxx-git to building from git? Could you add a printline to recursiveScan? 

Open mixxx/src/library/libraryscanner.cpp, on line 340, add:
qDebug() << dir.path() << dir.canonicalPath() << dir.absolutePath();

That would tell us what Mixxx thinks its scanning over and over.

You could also use strace to see what files its stat'ing repeatedly -- which would kind of tell us the same thing.

I'm now running a build from git fbc41067022e0c7876449813ce3142c16678fc6a

Using strace, it segfaults after 'stat()'ing /etc/localtime many times. I've attached the output.
