[libcamera-devel] [PATCH 0/4] Event dispatcher enhancements

[Laurent Pinchart]

Hello,

This patch series enhances the event dispatcher with two new features.
In patch 2/4 we get EINTR support to automatically restart the ppoll()
call if it gets interrupted by a signal, and in patch 3/4 the event
dispatcher API is extended with a function to interrupt in-progress
processEvents() calls. This is needed in order to interrupt event loops
gracefully.

The series starts in patch 1/4 by adding a test that fails, to outline
missing EINTR support, which is then fixed by patch 2/4. It ends with
another test case for the new EventDispatcher::interrupt() method.

Laurent Pinchart (4):
  tests: Test event dispatcher interruption by signal
  libcamera: event_dispatcher_poll: Handle interrupted ppoll() calls
  libcamera: event_dispatcher: Add interrupt() function
  tests: event-dispatcher: Add processEvents() interruption test
