[issue6562] OverflowError in RLock.acquire()

David Roberts added the comment: Ok, so if it's a bug in (Py)Qt then I'm not going to worry about it. I've managed to fix the issue in my case anyway, by (essentially) replacing: image = Image.open(fname) image.load() tile = ImageQt(image) with (the much more obvious way to do it):

Amaury Forgeot d'Arc added the comment: This error is certainly due to a C function that sets an exception but does not return an error value. When running with a debug build of python, you will see "XXX undetected error" printed to stderr. -- ___ Py

Fredrik Lundh added the comment: PIL is completely thread-agnostic, so I not sure there's anything PIL can do to fix this. (and ImageQt is of course an interface to PyQt, which is an interface to Qt, which consists of a *lot* more than 50 lines...) -- ___

Antoine Pitrou added the comment: I don't know, but you should probably contact the author, Fredrik Lundh, and/or post on the PIL list. Since it is probably not a bug in Python itself, I'm closing the issue. (please reopen if you discover a problem in Python itself) -- nosy: +effbot res

[issue6562] OverflowError in RLock.acquire()

David Roberts added the comment: I think I've narrowed it down to the ImageQt class provided by PIL - commenting out the reference to this (in the constructor of the Tile class referenced by TileProvider.run) stops the errors. So how do I go about determining where the problem with ImageQt lies

[issue6562] OverflowError in RLock.acquire()

David Roberts added the comment: Yes, it is the PIL library. Removing calls to Image.open() still results in the same error - the exception is thrown before it even reaches that bit of the code anyway. Another odd thing is that the exception is only thrown on some of the calls to get_tile_path,

David Roberts added the comment: thread.get_ident() returns 1192 and 1560 in the cases where there is no error, and 1316 in the case where the error is thrown. Doesn't seem particularly unusual, and shows get_ident() isn't throwing the error itself. I also noticed that there is a warning right
