* Switching the Cygwin DLL to LGPLv3+, dropping commercial buyout optioncygwin-2_5_2-releaseCorinna Vinschen2016-06-231-2/+0
| | | | | | | | | | | | | | Bump GPLv2+ to GPLv3+ for some files, clarify BSD 2-clause. Everything else stays under GPLv3+. New Linking Exception exempts resulting executables from LGPLv3 section 4. Add CONTRIBUTORS file to keep track of licensing. Remove 'Copyright Red Hat Inc' comments. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* * cygwin.din (sem_unlink): Export.Corinna Vinschen2007-02-201-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.
* * cygmalloc.h (MALLOC_FAILURE_ACTION): Define empty.Corinna Vinschen2007-02-071-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * cygwin.din (posix_madvise): Export. (posix_memalign): Export. * fhandler.cc (fhandler_base::fpathconf): Return useful values in _PC_VDISABLE, _PC_SYNC_IO and _PC_SYMLINK_MAX cases. * malloc_wrapper.cc (malloc): Set errno here since it's not set in dlmalloc.c anymore. (realloc): Ditto. (calloc): Ditto. (memalign): Ditto. (valloc): Ditto. (posix_memalign): New function. * mmap.cc (posix_madvise): New function. * sysconf.cc (get_open_max): New function. (get_page_size): Ditto. (get_nproc_values): Ditto. (get_avphys): Ditto. (sc_type): New type. (sca): New array to map _SC_xxx options to sysconf return values. (sysconf): Reimplement using sca array. * include/limits.h: Add all missing values as defined by SUSv3. * include/pthread.h (PTHREAD_DESTRUCTOR_ITERATIONS): Move definition to sys/limits.h. (PTHREAD_KEYS_MAX): Ditto. * include/semaphore.h (SEM_VALUE_MAX): Ditto. * include/cygwin/stdlib.h (posix_memalign): Declare. * include/cygwin/version.h: Bump API minor number. * include/sys/mman.h: Add posix_madvise flags. (posix_madvise): Declare. * include/sys/termios.h (_POSIX_VDISABLE): Move definition to sys/limits.h.
* * cygwin.din: Add sem_close, sem_getvalue, sem_open and sem_timedwait.Corinna Vinschen2003-10-271-0/+4

(sem_getvalue): Ditto. * thread.cc (semaphore::semaphore): Rearrange member initialization. Use appropriate security attribute for process shared semaphores. (semaphore::semaphore): New constructor for named semaphores. (semaphore::~semaphore): Care for semaphore name. (semaphore::_post): Accomodate failing ReleaseSemaphore. Use value returned by ReleaseSemaphore vor currentvalue. (semaphore::_getvalue): New method. (semaphore::_timedwait): Ditto. (semaphore::_fixup_after_fork): Rearrange. Don't fail for process shared semaphores. (semaphore::open): New method. (semaphore::timedwait): Ditto. (semaphore::post): Fix return value. Set errno appropriately.
