Remove TODO + comment. + (ipc_names): Add max_len member. Set to maximum length of the path + before tacking on the prefix path. Set prefix path for named semaphors + to /dev/shm, as on Linux. + (enum ipc_type_t): Change sem to semaphore to avoid name conflicts. + (check_path): Detect empty paths. Use ipc_names's max_len member. + Use __small_sprintf to create full object path name. Special case + semaphores. + (ipc_cond_init): Drop superfluous strcpy. + (class ipc_flock): New class to simplify file locking in subsequent + code. + (struct mq_hdr): Raise size of mqh_uname to allow adding a unique + LUID to the name. + (mq_open): Fix formatting. Create unique synchronization object names + using AllocateLocallyUniqueId. + (struct sem_finfo): New structure defining named semaphore file content. + (sem_open): Move here. Rework implementation to allow kernel + persistent implementation of POSIX named semaphores. + (_sem_close): Implement sem_close. + (sem_close): Move here. Just call _sem_close with do_close parameter + set to true. + (sem_unlink): New function. + * pthread.cc (mangle_sem_name): Remove. + (sem_open): Move to posix_ipc.cc. + (sem_close): Ditto. + * syscalls.cc (close_all_files): Call semaphore::terminate here. + * thread.cc: Fix formatting. Rearrange semaphore functions so that + they are close together. + (semaphore::semaphore): Rework to play nicely with new named semaphore + implementation. + (semaphore::_terminate): Call _sem_close if semaphore is a named + semaphore. + (semaphore::destroy): Don't destroy named semaphores. Return EINVAL + instead. + (semaphore::close): Only destroy named semaphores. Return EINVAL + otherwise. + (semaphore::open): Rework to play nicely with new named semaphore + implementation. Loop through existing semaphores to be able to + return same sem_t pointer as a former call on the same named semaphore. + (semaphore::getinternal): New function called from _sem_close. + * thread.h (class List): Make mx and head public. + (class semaphore): Fix formatting. Align method declarations with + implementation in thread.cc. Add members used for named semaphores. + (semaphore::terminate): New static method. + * include/semaphore.h: Redefine SEM_FAILED. Fix formatting. + (sem_unlink): Add declaration. + * include/cygwin/version.h: Bump API minor number. + 2007-02-20 Christopher Faylor <me@cgf.cx> * exceptions.cc (_cygtls::signal_exit): Only call myself.exit when when |
