(Updated Oct. 26, 2014, 7:10 a.m.) Review request for Asterisk Developers, George Joseph and rmudgett. Changes ------- Add support to notify that the real object associated with a weak object are being destroyed. Tweak ao2_weaken(weakobj) so it returns NULL if the real object associated with weakobj has already been destroyed. Repository: Asterisk Description ------- This implements weak references. The weak object is a real ao2 with normal reference counting of its own. The original object is destroyed when the only reference remaining is from the weak object. Diffs (updated) ----- /trunk/tests/test_astobj2_weaken.c PRE-CREATION /trunk/main/astobj2.c 426139 /trunk/include/asterisk/astobj2.h 426139 Diff: https://reviewboard.asterisk.org/r/4108/diff/ Testing ------- Very little, I'm unsure how to actually test that this cannot race, since any potential for a race would be due to very exact timing. Thanks, Corey Farrell
