| | * Fix log channel initialization at bionic/logd_write.c.Alexey Tarasov2009-12-031-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | log_channel_t contains fd member, which is file descriptor for exact logging channel. change cc05d1271680d6a7804bc89d3b1fe14c40b32396 lacks initialization of this member in __write_to_log_init(), thus logging code is not working, although not crashable.

* | | Use private futexes for pthread_mutex_t.David 'Digit' Turner2010-03-181-58/+129
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This does not change the implementation of conditional variables since we're waiting for other system components to properly use pthread_condattr_init/setpshared before that. Also remove an obsolete x86 source file. Change-Id: Ia3e3fbac35b87a534fb04d4381c3c66b975bc8f7
* | | Add pthread_condattr_init/destroy/setpshared/getpsharedDavid 'Digit' Turner2010-03-181-3/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Note that this does not change the implementation of conditional variables which still use shared futexes, independent on the flags being selected. This will be fixed in a later patch, once our system is modified to use pthread_condattr_setpshared(attr, PTHREAD_PROCESS_SHARED) properly. Change-Id: I935de50964cd41f97a13dbfd6626d3407b0406c3

* | | bionic: pthread: use private futexes by default for mutexes and condvarsDavid 'Digit' Turner2010-03-111-298/+493
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Private futexes are a recent kernel addition: faster futexes that cannot be shared between processes. This patch uses them by default, unless the PROCESS_SHARED attribute flag is used when creating a mutex and/or conditional variable. Also introduces pthread_condattr_init/destroy/setpshared/getpshared. Change-Id: I3a0e2116f467072b046524cb5babc00e41057a53

| | | | | | | | | | | | | | | | | | | | | | | | | | | Any of the setuid functions now updates /acct/uid/ with its own tid before changing users. This is so we can properly account for cpu time per uid. Change-Id: I34186cf4d5228cac8439e582a9e26c01ef3011e4 Signed-off-by: Mike Chan <mike@android.com>
* | | Fix pthread_sigmask() to return correct error values.David 'Digit' Turner2010-03-011-1/+11
| | | | | | | | | | | | | | | Before that, it returned -1 on error and set errno (not Posix) After the patch, it returns the error code and leaves errno untouched.

* | | Fix libc logging implementation.Andy McFadden2009-11-301-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | The file descriptor wasn't getting set, so the writev() call was silently failing. There's a parallel implementation over in system/core/liblog, but it's still using the old approach and didn't have this problem.

| | | | | | | | | | | | | | | | | | | | This change is intended to eliminate need to replace libc.so with libc_debug.so in order to enablememory allocation debugging. This is also the first step towards implementing extended memoryallocation debugging using emulator's capabilities in monitoring memory access.
