Hi,
I was trying to debug a deadlock while using gvim (with
libcanberra+pulse output: https://qa.mandriva.com/show_bug.cgi?id=44925)
I had reason to read the threaded loop docs.
The reference implementation shown here:
http://0pointer.de/lennart/projects/pulseaudio/doxygen/threaded_mainloop.html#basic_subsec
In my mind, the operation could theoretically be cancelled and this the
_get_state() will return PA_OPERATION_CANCELLED.
In the example code, if this happens, the loop will spin and the main
loop will never be unlocked.
This could be fixed by spinning when the state is PA_OPERATION_RUNNING
rather when it is not PA_OPERATION_DONE (incidentally, there is a typo
in the docs... it says OPERATION_RUNNING without the PA_ prefix...).
Anyway, any comments on this observation would be appreciated.
