2019-06-21Turn on warnings when building libap.Ori Bernstein
For ape, we never enabled warnings in cflags. Turning it on brings up a lot of warnings. Most are noise, but a few caught unused variables and trunctaions of pointers. to smaller integers (int, long). A few warnings remain.
2013-03-11ape: fix thread race with close() and select()cinap_lenrek
in ape close(), do the real filedescriptor _CLOSE() *after* we cleared the _fdinfo[] slot because once closed, we dont own the slot anymore and another process doing open() can trash the slot. make sure open() retuns fd < OPEN_MAX. double check in _startbuf() holding mux->lock if the fd is already buffered preveting running double copyprocs on a fd. dont zero the mux->rwant/ewant bitmaps at the end of select() as we do not hold the mix->lock. in _closebuf() kill copyproc while holding the mux->lock to make sure the copyproc isnt holding it at the time it is killed. run kill() multiple times to make sure the proc is gone.
