* libc: fix fstatfs() implementation.David 'Digit' Turner2010-07-082-4/+4
| | | | | | The syscall expects the size of the buffer as the second argument. Change-Id: I99ede2fec7fcd385ca03ff022c2cffa4297bea8d
* Allow static C++ destructors to be properly called on dlclose().David 'Digit' Turner2010-06-182-9/+6
| | | | | | | | | | | | | | | | | | | | | | | With this patch, _and_ an upcoming build/ patch, the destruction of static C++ objects contained in shared libraries will happen properly when dlclose() is called. Note that this change introduces crtbegin_so.S and crtend_so.S which are currently ignored by the build system. + move definition of __dso_handle to the right place (before that, all shared libraries used the __dso_handle global variable from the C library). Note that we keep a 'weak' __dso_handle in aeabi.c to avoid breaking the build until the next patch to build/core/combo/ appears. We will be able to remove that later. + move bionic/aeabi.c to arch-arm/bionic/ (its proper location) Change-Id: Ie771aa204e3acbdf02fd30ebd4150373a1398f39 NOTE: The NDK will need to be modified to enable this feature in the shared libraries that are generated through it.

* Use private futexes for pthread_mutex_t.David 'Digit' Turner2010-03-181-0/+10
| | | | | | | | | | 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

* bionic: pthread: use private futexes by default for mutexes and condvarsDavid 'Digit' Turner2010-03-111-0/+18
| | | | | | | | | | 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
* bonic: libc: cpuacct support for setuid functionsMike Chan2010-03-024-12/+12
| | | | | | | | | 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>

* Implement clone() C library function properly.David 'Digit' Turner2010-01-253-5/+13
| | | | | | | Only provide an implementation for ARM at the moment, since it requires specific assembly fragments (the standard syscall stubs cannot be used because the child returns in a different stack).
