(wininfo::itv): Ditto. (wininfo::start_time): Ditto. (wininfo::window_started): Ditto. (wininfo::getitimer): Ditto. (wininfo::setitimer): Ditto. (wininfo::wininfo): Ditto. (wininfo::lock): New method. (wininfo::release): Ditto. * window.cc: Use new lock/acquire wininfo methods throughout. (wininfo::wininfo): Delete (wininfo::getitimer): Ditto. (wininfo::setitimer): Ditto. (getitimer): Ditto. (setitimer): Ditto. (ualarm): Ditto. (alarm): Ditto. (wininfo::lock): Define new function. (wininfo::release): Ditto. (wininfo::process): Delete WM_TIMER handling. * timer.cc (struct timetracker): Delete it, flags. Add it_interval, interval_us, sleepto_us, running, init_muto(), syncthread, and gettime(). (ttstart): Make NO_COPY. (lock_timer_tracker): New class. (timer_tracker::timer_tracker): Distinguish ttstart case. (timer_tracker::~timer_tracker): New destructor. Clean out events, and reset magic. (timer_tracker::init_muto): New method. (to_us): Round up as per POSIX. (timer_thread): Reorganize to match timer_tracker::settime and timer_tracker::gettime. Call sig_send without wait. Call auto_release. (timer_tracker::settime): Reorganize logic to avoid race. Call gettime to recover old value. (timer_tracker::gettime): New method. (timer_create): Properly set errno on invalid timerid. Use new lock_timer_tracker method. (timer_delete): Ditto. Simplify code slightly. (timer_gettime): New function. (fixup_timers_after_fork): Reinit ttstart. (getitimer): New implementation. (setitimer): Ditto. (ualarm): Ditto. (alarm): Ditto. * cygwin.din: Export timer_gettime. * winsup.h: Remove has has_visible_window_station declaration. * Makefile.in (DLL_OFILES): Add lsearch.o. * cygthread.h (cygthread::notify_detached): New element. (cygthread::cygthread): Take optional fourth argument signifying event to signal on thread completion. * cygthread.cc (cygthread::stub): Signal notify_detached event, if it exists. (cygthread::cygthread): Initialize notify_detached from fourth argument. (cygthread::detach): Wait for notify_detached field is present. * lsearch.cc: New file. * search.h: Ditto. * include/cygwin/version.h: Bump API minor number to 126. * cygwin.din: Export lsearch, lfind. --- winsup/cygwin/exceptions.cc | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) (limited to 'winsup/cygwin/exceptions.cc') diff --git a/winsup/cygwin/exceptions.cc b/winsup/cygwin/exceptions.cc index 277bd713a..1de0bf976 100644 --- a/winsup/cygwin/exceptions.cc +++ b/winsup/cygwin/exceptions.cc @@ -10,6 +10,8 @@ Cygwin license.
