winsup/cygserver: ChangeLog bsd_helper.cc bsd_mutex.cc
bsd_mutex.h cygserver.cc process.cc
sysv_sem.cc sysv_shm.cc
Log message:
* 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.
