#430: Threaded mainloop API steals signals unnecessarily
-----------------------+----------------------------------------------------
Reporter: jcornwall | Owner: lennart
Type: defect | Status: new
Priority: normal | Milestone:
Component: libpulse | Severity: normal
Keywords: |
-----------------------+----------------------------------------------------
The following code in src/pulse/threaded-mainloop.c:
{{{
/* Make sure that signals are delivered to the main thread */
sigfillset(&mask);
pthread_sigmask(SIG_BLOCK, &mask, NULL);
}}}
Interferes badly with client applications that use signals for other
purposes, including the Mono runtime environment. This functionality is
only needed when pa_signal_init() has been called but is indiscriminately
applied to all clients, when only a fraction will use this feature.
Attached is a patch to conditionally run this code when pa_signal_init()
has been called. Because mainloop-signal.c is API-agnostic wiring the two
together is tricky, so I opted to add an internal (exposed but not
exported) API-agnostic function to act as a buffer. The patched library
works with signal-dependent applications and does not alter functionality
in other applications where pa_signal_init() is called, as it must before
using signalling features.
