Romain Beauxis resolved LS-537.
-------------------------------
Assignee: Romain Beauxis
Fix Version/s: 1.0
Resolution: Fixed
Fixed in 8a446c71e509:
Releasing the Gc lock inside a finalization function was not a good idea!
This was in fact causing a global memory inconsistency, with logs of the
form:
2011/06/21 23:23:15 [decoder:4] Decoder "OGG" failed on "foo.ogg": Bad file
descriptor in lseek()!
Thus, opening API in Vorbis.File has been changed:
* No close callback is passed.
* If no close callback is passed, ov_clear does not
mess with the Gc, thus removing the calls to
grab ocaml global lock.
* Removed exported close function and put all cleaning
in the finalization function.
* Thus, return a Unix.file_descr when opening
a file.
* Changed file opening function to more consistent names.

> Wen seeking under stress, liquidsoap can segfault, most likely in relation
> with the Gc.
> Attached is a script from David to reproduce it.
> So far, I have noted that it does happen with only ogg decoding enabled and
> that it may not be related to a finalisation.
> I suspect something fishy around the ogg sync code as it is full of caml
> callbacks from C but it may be something else..
