"[ 1901956 ] wxMac: TECConvertText not thread safe"


--- Quote ---It seems that the mac carbon function TECConvertText is not thread safe.
This causes problems in applications that use say wxFileExists() and
friends in separate threads. Applications that make calls to
TECConvertText in separate threads crash randomly sooner or later.

^ the above would be Code::Blocks

afb:
I have applied the suggested patch to my wxWidgets (libwx_macu_gl-2.8.0.4.0.dylib), so it will go out with the next nightly. It seems to fix the threading issues / application crashes, at least I can't provoke it the same way now.

thomas:
Ah darn, I had just written a Mac-stupefier for those functions in Code::Blocks... but well, it's probably nicer if you just use a patched wxMac and that crap that stays out of our sources. :)

Taking a wxMutex on all file access ? Or did you do something that the patch won't fix ?

No, just that... a self-locking wrapper for the two problematic functions.

But it's of course preferrable to have it patched into wxMac. Not only does it not pollute the Code::Blocks sources that way, but it also requires less changes and fixes yet unknown issues with future contrib plugins (whose authors might not know).
