Just wait for sigthread here. * dll_init.cc (cygwin_detach_dll): Only pick up tls version of retaddr if we have a valid tls. * fork.cc (frok::child): Remove sigproc_init initialization since it happens much earlier now. * gendef: Recognize SIGFE_MAYBE. (fefunc): Generate calls to _sigfe_maybe, if appropriate. (_sigfe_maybe): New function. * init.cc (search_for): Always initialize search_for, even on fork. (calibration_thread): Delete. (calibration_id): Delete. (prime_threads): Delete. (munge_threadfunc): Remove calibration_thread special case. Avoid calling thread function if we haven't yet hit the "search_for" thread. (dll_entry): Remove prime_threads call. Only call munge_threadfunc when hwait_sig is active. Ditto. for _my_tls.remove (); * sigproc.cc (hwait_sig): Make global. (sigproc_init): Don't bother with sync_startup. (sig_send): Treat flush as a no-op when signals are held. (wait_sig): Cause signals to be held after fork.
* * cygtls.h (_cygtls::retaddr): New method.Christopher Faylor2006-03-081-0/+1
| | | | | | | * dll_init.cc (cygwin_detach_dll): Use new tls function to find return address since this function is now signal guarded. (update_envptrs): Remove unneeded braces. * syscalls.cc (statvfs): Coerce full_path to avoid a gcc warning.
* Always zero all elements of siginfo_t throughout.Christopher Faylor2006-02-061-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | * cygtls.h (_cygtls::thread_context): Declare new field. (_cygtls::thread_id): Ditto. (_cygtls::signal_exit): Move into this class. (_cygtls::copy_context): Declare new function. (_cygtls::signal_debugger): Ditto. * cygtls.cc (_cygtls::init_thread): Fill out thread id field. * exceptions.cc (exception): Change message when exception info is unknown. Copy context to thread local storage. (_cygtls::handle_exceptions): Avoid double test for fault_guarded. Reflect move of signal_exit to _cygtls class. (sigpacket::process): Copy context to thread local storage. (_cygtls::signal_exit): Move to _cygtls class. Call signal_debugger to notify debugger of exiting signal (WIP). Call stackdump here (WIP). (_cygtls::copy_context): Define new function. (_cygtls::signal_debugger): Ditto. * tlsoffsets.h: Regenerate. * include/cygwin.h (_fpstate): New internal structure. (ucontext): Declare new structure (WIP). (__COPY_CONTEXT_SIZE): New define. * exceptions.cc (_cygtls::interrupt_setup): Clear "threadkill" field when there is no sigwaiting thread. (setup_handler): Move event handling into interrupt_setup.
