* * fork.cc: White space.Christopher Faylor2007-07-071-23/+23
| | | | | * net.cc: Ditto. * posix_ipc.cc: Ditto.
* * cygheap.cc (cygheap_init): Fix formatting. Remove comment. SetCorinna Vinschen2007-03-291-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | shared_prefix depending only on terminal service capability. * dcrt0.cc (dll_crt0_1): Don't call set_cygwin_privileges here. * fhandler_fifo.cc (fhandler_fifo::open): Create the mutex as global object. * posix_ipc.cc (ipc_mutex_init): Use cygheap->shared_prefix. (ipc_cond_init): Ditto. * sec_helper.cc (privilege_name): Make static. Use LookupPrivilegeName directly to be independent of the state of cygheap. (set_privilege): Take a LUID as parameter instead of an index value. Only print debug output in case of failure. (set_cygwin_privileges): Add comment. Use LookupPrivilegeValue to get privilege LUIDs. (init_global_security): Call set_cygwin_privileges here. * security.h (privilege_name): Drop declaration. (set_privilege): Declare according to above change. (set_process_privilege): Call privilege_luid to get LUID. (_push_thread_privilege): Ditto. * shared.cc (open_shared): Add comment. On systems supporting the SeCreateGlobalPrivilege, try to create/open global shared memory first. Fall back to local shared memory if that fails. * thread.cc (semaphore::semaphore): Use cygheap->shared_prefix. * wincap.h (wincapc::has_create_global_privilege): New element. * wincap.cc: Implement above element throughout.
* * cygwin.din (sem_unlink): Export.Corinna Vinschen2007-02-201-18/+219
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * posix_ipc.cc: Include thread.h and semaphore.h. 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.
* * posix_ipc.cc (mq_open): Avoid compiler warning. Initialize mqhdrCorinna Vinschen2007-02-151-2/+2
| | | | | before using it in file exists case. * include/mqueue.h (mqd_t): Make non-pointer type.
* * posix_ipc.cc (ipc_mutex_init): Create global object name.Corinna Vinschen2007-02-151-26/+26
| | | | | | | | | (ipc_cond_init): Ditto. (struct mq_hdr): Add mqh_uname member to store synchronization object name. (mq_open): Create unique synchronization object name and store in mq_hdr->mqh_uname. Use this name in calls to ipc_mutex_init and ipc_cond_init.
* * Makefile.in (DLL_OFILES): Add posix_ipc.o.Corinna Vinschen2007-02-141-0/+849
* cygwin.din (mq_close): Export. (mq_getattr): Export. (mq_notify): Export. (mq_open): Export. (mq_receive): Export. (mq_send): Export. (mq_setattr): Export. (mq_timedreceive): Export. (mq_timedsend): Export. (mq_unlink): Export. * posix_ipc.cc: New file implementing the above functions. Move shm_open and shm_unlink from syscalls.cc here. * sysconf.cc (sca): Set value of _SC_MQ_OPEN_MAX to MQ_OPEN_MAX, _SC_MQ_PRIO_MAX to MQ_PRIO_MAX, _SC_MESSAGE_PASSING to _POSIX_MESSAGE_PASSING. * include/limits.h (MQ_OPEN_MAX): Define. (MQ_PRIO_MAX): Define. * include/mqueue.h: New file. * include/cygwin/version.h: Bump API minor number.
