* Throughout, use __try/__except/__endtry blocks, rather than myfault handler. * cygtls.cc (_cygtls::remove): Accommodate the fact that pathbufs has been moved from _local_storage to _cygtls. * cygtls.h (class tls_pathbuf): Add comment to hint to gendef usage of counters. Change type of counters to uint32_t for clarity. Remove _cygtls as friend class. (struct _local_storage): Move pathbufs from here... (struct _cygtls): ...to here, allowing to access it from _sigbe. (class san): Only define on 32 bit. Remove errno, _c_cnt and _w_cnt members. (san::setup): Drop parameter. Don't initialize removed members. (san::leave): Don't set removed members. (class myfault): Only define on 32 bit. (myfault::faulted): Only keep implementation not taking any parameter. Drop argument in call to sebastian.setup. (__try/__leave/__except/__endtry): Implement to support real SEH. For now stick to SJLJ on 32 bit. * dcrt0.cc (dll_crt0_0): Drop 64 bit call to exception::install_myfault_handler. * exception.h (exception_handler): Define with EXCEPTION_DISPOSITION as return type. (PDISPATCHER_CONTEXT): Define as void * on 32 bit. Define as pointer to _DISPATCHER_CONTEXT on 64 bit. (class exception): Define separately for 32 and 64 bit. (exception::myfault): Add handler for myfault SEH handling on 64 bit. (exception::exception): Fix mangled method name to account for change in type of last parameter. (exception::install_myfault_handler): Remove. * exceptions.cc (exception::myfault_handle): Remove. (exception::myfault): New SEH handler for 64 bit. * gendef (_sigbe): Set tls_pathbuf counters to 0 explicitely when returning to the caller. * ntdll.h: Move a comment to a better place. (struct _SCOPE_TABLE): Define on 64 bit. * thread.cc (verifyable_object_isvalid): Remove gcc 4.7 workaround. * tls_pbuf.cc (tls_pbuf): Fix to accommodate new place of pathbufs. (tls_pathbuf::destroy): Change type of loop variables to uint32_t. * tls_pbuf.h (class tmp_pathbuf): Change type of buffer counters to uint32_t. Accommodate new place of pathbufs. * tlsoffsets.h: Regenerate. * tlsoffsets64.h: Regenerate.

Some caveats: PROCESS_SHARED objects, while they pretend to be process
2001-09-12 12:47:47 +08:00
shared, may not actually work. Some test cases are needed to determine
win32's behaviour. My suspicion is that the win32 handle needs to be
opened with different flags for proper operation.

pthread_null::getsequence_np ()
2002-09-11 Robert Collins <rbtcollins@hotmail.com> * init.cc (dll_entry): On thread detach, if the thread hasn't exit()ed, do so. * pthread.cc (pthread_getsequence_np): Remove the __pthread_getsequence_np wrapper. This requires errno.h. * thread.cc (pthread::self): Instantiate a new pthread object when called and none exists. return a NULL object if instantiation fails. (pthread::precreate): Factor out common code. (pthread::postcreate): Ditto. (pthread::create): Ditto. (pthread::exit): Remove the TLS value when we exit to prevent double exits. (MTinterface::Init): Bugfix - don't mark the TLS index as created if one was not allocated. Apply Extract Method to move pthread specific initialisation into pthread. (pthread::initMainThread): Extracted method from MTinterface::Init. (pthread::setTlsSelfPointer): Extracted method from various pthread calls, to make reading those functions easier. (pthread::setThreadIdtoCurrent): Ditto. (pthread::cancel_self): Bring into the .cc file, it's only used within the class. (pthread::getThreadId): Ditto. (pthread::thread_init_wrapper): Apply Extract Method to the TLS setting logic. (pthread::isGoodObject): Extracted method from various pthread wrapper calls, for clarity of reading. (pthread::getsequence_np): Converted from __pthread_getsquence_np. (__pthread_create): Apply Extract Method to the object validation. (__pthread_cancel): Ditto. (__pthread_join): Ditto. (__pthread_detach): Ditto. (__pthread_suspend): Ditto. (__pthread_continue): Ditto. (__pthread_getschedparam): Ditto. (__pthread_getsequence_np): Remove. (__pthread_setschedparam): Apply Extract Method to the object validation. (pthreadNull::getNullpthread): New method, return the pthreadNull object. (pthreadNull::pthreadNull): Private constructor to prevent accidental use. (pthreadNull::~pthreadNull): Prevent compile warnings. (pthreadNull::create): Override pthread behaviour. (pthreadNull::exit): Ditto. (pthreadNull::cancel): Ditto. (pthreadNull::testcancel): Ditto. (pthreadNull::setcancelstate): Ditto. (pthreadNull::setcanceltype): Ditto. (pthreadNull::push_cleanup_handler): Ditto. (pthreadNull::pop_cleanup_handler): Ditto. (pthreadNull::getsequence_np): Ditto. (pthreadNull::_instance): Ditto. * thread.h (pthread): Declare pre- and post-create. Move GetThreadId to private scope and rename to getThreadId. Move setThreadIdtoCurrent to private scope. Make create virtual. Make ~pthread virtual. Declare initMainThread. Declare isGoodObject. Make exit virtual. Make cancel virtual. Make testcancel virtual. Make setcancelstate virtual. Make setcanceltype virtual. Make push_cleanup_handler virtual. Make pop_cleanup_handler virtual. Declare getsequence_np. Declare setTlsSelfPointer. (pthreadNull): New null object class for pthread. (__pthread_getsequence_np): Remove.
