Refactoring ags_channel.c

Item posted by Joël Krähemann <jkraehemann> on Sat 23 Dec 2017 11:47:54 AM UTC.

Some key functions are going to be refactored, these are:

  • ags_channel_recursive_play_init()
  • ags_channel_recursive_play()
  • ags_channel_recursive_reset_recall_ids()
  • ags_channel_tillrecycling_cancel()

The problem with them is they are really old and don't do their job correct. They have redundant code and were never intended to run in a non thread-safe context. This issue is going to be targeted by the new functions:

  • ags_channel_get_level()
  • ags_channel_recursive_reset_recall_id()
  • ags_channel_recursive_init()
  • ags_channel_recursive_run()
  • ags_channel_recursive_cancel()

One more problem with the old code is the schema wasn't correct applied recursive. Causing some SIGSEGV, however the model is mature and it is possible to fix it.

AgsRecyclingContext thread-safe

The AgsRecyclingContext has got its very own mutex. Thought it is not provided by AgsMutexManager, you can access it by the structs field.

Sorry for screwing things

Running the user interface asynchronously is really tough. There had to be added many mutex locks. And I screwed things, sorry. But this is a great occasion to solve some really old problems the engine had.
