* Use umtx to implement process sharable semaphore, to make this work,davidxu2010-01-0512-311/+854
| | | | | | | | | | | | | | | | | | | | | | now type sema_t is a structure which can be put in a shared memory area, and multiple processes can operate it concurrently. User can either use mmap(MAP_SHARED) + sem_init(pshared=1) or use sem_open() to initialize a shared semaphore. Named semaphore uses file system and is located in /tmp directory, and its file name is prefixed with 'SEMD', so now it is chroot or jail friendly. In simplist cases, both for named and un-named semaphore, userland code does not have to enter kernel to reduce/increase semaphore's count. The semaphore is designed to be crash-safe, it means even if an application is crashed in the middle of operating semaphore, the semaphore state is still safely recovered by later use, there is no waiter counter maintained by userland code. The main semaphore code is in libc and libthr only has some necessary stubs, this makes it possible that a non-threaded application can use semaphore without linking to thread library. Old semaphore implementation is kept libc to maintain binary compatibility. The kernel ksem API is no longer used in the new implemenation. Discussed on: threads@
* Modernize scandir(3) and alphasort(3) interfaces according to the IEEEkib2010-01-043-18/+15
| | | | | | | | | | | | | | | | | | | | Std 1003.1-2008. Both Linux and Solaris conforms to the new definitions, so we better follow too (older glibc used old BSDish alphasort prototype and corresponding type of the comparision function for scandir). While there, change the definitions of the functions to ANSI C and fix several style issues nearby. Remove requirement for "sys/types.h" include for functions from manpage. POSIX also requires that alphasort(3) sorts as if strcoll(3) was used, but leave the strcmp(3) call in the function for now. Adapt in-tree callers of scandir(3) to new declaration. The fact that select_sections() from catman(1) could modify supplied struct dirent is a bug. PR: standards/142255 MFC after: 2 weeks
