Description Maciej (Matthew) Piechotka 2013-08-09 20:24:05 UTC

Empathy can sometimes crash during startup due to too many files. I guess it might be due to slow I/O:

warning: Could not load shared library symbols for linux-vdso.so.1.
Do you need "set solib-search-path" or "set sysroot"?
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".
Core was generated by `empathy'.
Program terminated with signal 5, Trace/breakpoint trap.

Re-assigning to folks as it's opening files from Folks's cache.

core: Rate-limit AvatarCache.store_avatar() to prevent FD exhaustion

If connecting to a new EDS address book, or doing something else which
may cause a torrent of AvatarCache.store_avatar() calls, it is possible
to hit the operating system’s file descriptor limit, which causes
further store operations to fail.

Implement a simple FIFO rate limit on concurrent
AvatarCache.store_avatar() calls to try and ensure this won’t happen. It
is still possible if the process calls store_avatar() several times
while already near the FD limit, but then failure is pretty inevitable
anyway, and is already handled gracefully.

The changes are implemented in a self-contained wrapper function around
store_avatar(), and only result in memory allocations in the queueing
case.

A test case is included. This does not affect the AvatarCache API or
ABI.

Comment 3 Philip Withnall 2014-04-06 10:23:02 UTC

This is caused by too many concurrent calls to AvatarCache.store_avatar(), which then opens two FDs (one to read the avatar from its current location, which is probably actually a network socket; and one to store it locally on disk). These FDs are closed correctly afterwards, but if too many operations are started in parallel, FD exhaustion will occur.

The above is a simple patch to implement FIFO rate limiting on AvatarCache.store_avatar(). It includes a test case (shock! horror!).

What this patch does *not* fix is any case in Empathy where AvatarCache.load_avatar() is called many times in parallel. Any FD exhaustion occurring as a result of that can’t be fixed in folks because folks returns a LoadableIcon — the g_loadable_icon_load() call will be inside Empathy somewhere. I haven’t investigated whether this could actually be a problem in Empathy though. Certainly the stack trace in comment #0 shows the problem being caused by AvatarCache.store_avatar() calls. (Thanks for the detailed bug report, by the way, Maciej!)

Sorry it took so long to get round to this. I was hoping to avoid fixing it by eliminating AvatarCache entirely (it should really be implemented in EDS and Tracker, rather than in folks), but that’s a much bigger job.
