From 82c925af80cb4493cc15861c18fea64c57c2ee60 Mon Sep 17 00:00:00 2001 From: Christopher Faylor Date: Sun, 23 Oct 2005 23:47:45 +0000 Subject: * cygheap.h (cygheap_fdenum::cygheap_fdenum): Record locked state or suffer deadlocks. (class locked_process): Move to another header. * sync.h (lock_process): Define here. * cygtls.cc (_cygtls::fixup_after_fork): Reset spinning state as well as stacklock state. * dcrt0.cc (lock_process::locker): Define. (dtable::lock_cs): Delete. * dtable.cc (dtable_init): Eliminate call to init_lock(). (dtable::fixup_after_fork): Ditto. (dtable::init_lock): Delete definition. * dtable.h (dtable::init_lock): Delete declaration. (dtable::lock): Use process lock rather than dtable-specific lock. (dtable::unlock): Ditto. * sigproc.cc (sigproc_init): Minor change to debugging output. * times.cc (utime_worker): Use build_fh_pc rather than reinterpreting the posix path name again. Return any error from path_conv immediately. --- winsup/cygwin/sync.h | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) (limited to 'winsup/cygwin/sync.h') diff --git a/winsup/cygwin/sync.h b/winsup/cygwin/sync.h index 441892a08..f8019a8fe 100644 --- a/winsup/cygwin/sync.h +++ b/winsup/cygwin/sync.h @@ -44,4 +44,28 @@ public: static void set_exiting_thread () {exiting_thread = GetCurrentThreadId ();} }; +class lock_process +{ + bool skip_unlock; + static muto locker; +public: + static void init () {locker.init ("lock_process");} + lock_process (bool exiting = false) + { + locker.acquire (); + skip_unlock = exiting; + if (exiting && exit_state < ES_SET_MUTO) + { + exit_state = ES_SET_MUTO; + muto::set_exiting_thread (); + } + } + ~lock_process () + { + if (!skip_unlock) + locker.release (); + } + friend class dtable; +}; + #endif /*_SYNC_H*/ -- cgit v1.2.3
