* bsd_helper.cc (ipcexit_hookthread): Fix whitespace and handle leak.
* bsd_mutex.cc: Include stdlib.h, sys/msg.h and sys/sem.h. (mtx_init): Initialize lock counter to 0. (_mtx_lock): Increment and log mutex lock counter. (mtx_owned): Add winpid argument. Return true only if mutex is actually owned by process winpid. (_mtx_assert): Add winpid argument accordingly. (_mtx_unlock): Log owner and lock count. (MSLEEP_MUTEX): Remove. (MSLEEP_SEM): Ditto. (MSLEEP_EVENT): Ditto. (msleep_event_name): Ditto. (msleep_cs): New global critical section. (msleep_cnt): New global variable indicating msleep record usage. (msleep_max_cnt): New global variable indicating msleep record size. (msleep_arr): New global pointer to msleep records. (msleep_init): Initialize msleep_cs. Allocate msleep_arr array. (_msleep): Rewrite using new msleep_cs/msleep_arr based thread synchronization. Don't be shy with debug output. (wakeup): Rewrite using new msleep_cs/msleep_arr based thread synchronization. * bsd_mutex.h (struct mtx): Add lock counter for better debugging. (mtx_owned): Declare with winpid argument. (_mtx_assert): Ditto. (mtx_assert): Define with winpid argument. * cygserver.cc (version): Remove. (SERVER_VERSION): New define, decoupling server version information from source code control system. (print_version): Simplify printing server version. * process.cc (process::process): Fix wrong bracketing (and handle leak). (process::~process): Only try to close _signal_arrived if valid. * sysv_sem.cc: Include sys/smallprint.h. (semundo_clear): Define with additional struct thread pointer argument. Accomodate throughout. (SEMUNDO_LOCKASSERT): Define with winpid argument. Accomodate throughout. (struct sem_undo): Define un_proc as pid_t on Cygwin. Accomodate throughout. (seminit): Improve debugging by adding the semid to the mutex name. (semget): Correctly print key value as 64 bit hex value in debug output. (semexit_myhook): Remove Cygwin specific unlocking of mutexes owned by exiting process. Keep semaphore global lock throughout whole function to avoid races. * sysv_shm.cc (GIANT_REQUIRED): Define empty on Cygwin. We know that Giant is locked. |
