From e431827c7cab81292e8cd4ec9d3a4a60b35a42f2 Mon Sep 17 00:00:00 2001 From: Christopher Faylor Date: Thu, 12 Feb 2004 03:01:58 +0000 Subject: Rename _threadinfo to _cygtls, throughout. * cygtls.h (_cygtls::call_signal_handler): Rename from call_signal_handler_now. (_cygtls::push): Make second argument mandatory. (_cygtls::fixup_after_fork): Declare new function. (_cygtls::lock): Ditto. * cygtls.cc (_cygtls::fixup_after_fork): Define new function. * dcrt0.cc (cygwin_finished_initializing): Define as bool. (alloc_stack): Use _tlstop rather than arbitrary variable in probably vain attempt to avoid strange fork problem on CTRL-C. (dll_crt0_0): Remove obsolete winpids::init call. * dll_init.cc (dll_dllcrt0): Detect forkee condition as equivalent to initializing. * winsup.h (cygwin_finished_initializing): Declare as bool. * exceptions.cc (handle_exceptions): Rely on cygwin_finished_initializing to determine how to handle exception during process startup. (_cygtls::call_signal_handler): Rename from call_signal_handler_now. (_cygtls::interrupt_now): Fill in second argument to push. (signal_fixup_after_fork): Eliminate. (setup_handler): Initialize locked to avoid potential inappropriate unlock. Resume thread if it has acquired the stack lock. (ctrl_c_handler): Just exit if ctrl-c is hit before cygiwn has finished initializing. * fork.cc (sync_with_child): Don't call abort since it can cause exit deadlocks. (sync_with_child): Change debugging output slightly. (fork_child): Set cygwin_finished_initializing here. Call _cygtls fork fixup and explicitly call sigproc_init. (fork_parent): Release malloc lock on fork failure. (vfork): Call signal handler via _my_tls. * sigproc.cc (sig_send): Ditto. * syscalls.cc (readv): Ditto. * termios.cc (tcsetattr): Ditto. * wait.cc (wait4): Ditto. * signal.cc (nanosleep): Ditto. (abort): Ditto. (kill_pgrp): Avoid killing self if exiting. * sync.cc (muto::acquire): Remove (temporarily?) ill-advised exiting_thread check. * gendef (_sigfe): Be more agressive in protecting stack pointer from other access by signal thread. (_cygtls::locked): Define new function. (_sigbe): Ditto. (_cygtls::pop): Protect edx. (_cygtls::lock): Use guaranteed method to set eax to 1. (longjmp): Aggressively protect signal stack. * miscfuncs.cc (low_priority_sleep): Reduce "sleep time" for secs == 0. * pinfo.cc (winpids::set): Counterintuitively use malloc's lock to protect simultaneous access to the pids list since there are pathological conditions which can cause malloc to call winpid. (winpids::init): Eliminate. * pinfo.h (winpids::cs): Eliminate declaration. * pinfo.h (winpids::init): Eliminate definition. --- winsup/cygwin/sigproc.h | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'winsup/cygwin/sigproc.h') diff --git a/winsup/cygwin/sigproc.h b/winsup/cygwin/sigproc.h index e9c762112..1176c919c 100644 --- a/winsup/cygwin/sigproc.h +++ b/winsup/cygwin/sigproc.h @@ -54,7 +54,7 @@ struct sigpacket { siginfo_t si; pid_t pid; - class _threadinfo *tls; + class _cygtls *tls; sigset_t *mask; union { @@ -91,9 +91,8 @@ void __stdcall subproc_init (); void __stdcall sigproc_terminate (); bool __stdcall proc_exists (_pinfo *) __attribute__ ((regparm(1))); bool __stdcall pid_exists (pid_t) __attribute__ ((regparm(1))); -int __stdcall sig_send (_pinfo *, siginfo_t&, class _threadinfo *tls = NULL) __attribute__ ((regparm (3))); +int __stdcall sig_send (_pinfo *, siginfo_t&, class _cygtls *tls = NULL) __attribute__ ((regparm (3))); int __stdcall sig_send (_pinfo *, int) __attribute__ ((regparm (2))); -void __stdcall signal_fixup_after_fork (); void __stdcall signal_fixup_after_exec (); void __stdcall wait_for_sigthread (); void __stdcall sigalloc (); -- cgit v1.2.3
