From f6936c48f382a12b7b67fda40352b8e377662743 Mon Sep 17 00:00:00 2001 From: Christopher Faylor Date: Mon, 19 Jan 2004 05:46:54 +0000 Subject: * cygwin/include/signal.h: Add copyright notice. * cygwin.din: Make clock SIGFE. Add clock_gettime, sigwaitinfo, timer_create, timer_delete, timer_settime. * include/cygwin/version.h: Reflect above additions. * fork.cc (fork_child): Call fixup_timers_after_fork. * signal.cc (sigwait): Remove unused variable. * timer.cc: New file. (clock_gettime): Define new function. (timer_tracker): Define new struct used by timer functions. (timer_tracker::timer_tracker): New function. (to_us): New function. (timer_thread): New function. (timer_tracker::settime): New function. (timer_create): New function. (timer_settime): New function. (timer_delete): New function. (fixup_timers_after_fork): New function. * cygthread.cc: Bump thread count. * signal.cc (sigwaitinfo): Define new function. (sigwait): Redefine based on sigwaitinfo. * include/cygwin/signal.h (sigwaitinfo): Declare. (sigwait): Ditto. * dtable.cc (dtable::vfork_parent_restore): Avoid double close of ctty when ctty == ctty_on_hold. * cygtls.h (_threadinfo::threadkill): New element. (_threadinfo::set_threadkill): Declare new function. (_threadinfo::reset_threadkill): Declare new function. * dcrt0.cc (dcrt0_1): Call here so that it will be possible to attach to running process with #(*& Windows Me/9x. (initial_env): Try to initialize strace if uninitialized. * gendef: Don't zero signal if threadkill is set since that will happen in the called function. * signal.cc (sigwait): Ensure cleanup in error conditions. * sigproc.cc (sig_send): Clear packet mask storage. (wait_subproc): Fill in child exit code in siginfo_t structure. * thread.cc (pthread_kill): Set threadkill flag. * tlsoffsets.h: Regenerate. Throughout, use siginfo_t to fill out all signal information for "kernel" signals. * cygtls.h (_threadinfo::set_siginfo): Declare new function. * cygtls.cc (_threadinfo::set_siginfo): Define new function. * dcrt0.cc (do_exit): Accommodate siginfo_t considerations. * exceptions.cc (handle_exceptions): Ditto. (sig_handle_tty_stop): Ditto. (ctrl_c_handler): Use killsys() to send signal. (sigpacket::process): Rename from sig_handle. Use siginfo_t field from sigpacket for everything. (tty_min::kill_pgrp): Accommodate siginfo_t considerations. (fhandler_termios::bg_check): Ditto. * fhandler_tty.cc (fhandler_tty_slave::ioctl): Use killsys() to send signal. * signal.cc (kill_worker): Rewrite to use siginfo_t second argument. (kill_pgrp): Ditto. (kill0): Define new function pulled from kill(). (kill): Rewrite as frontend to kill0. (killsys): Define new function. * sigproc.cc (sigelem): Eliminate. (sigpacket): Move to sigproc.h. Subsume sigelem. (pending_signals): Use sigpacket rather than sigelem for everything. (sig_clear): Ditto. (wait_sig): Ditto. (sig_send): Rewrite to use siginfo_t argument. (sig_send): New function wratpper to sig_send with siginfo_t argument. (wait_subproc): Accommodate siginfo_t considerations. * thread.cc (pthread_kill): Ditto. * sigproc.h (sigpacket): Move here. (sigpacket::process): Declare "new" function. (sig_handle): Eliminate declaration. (sig_send): Declare with new paramaters. (killsys): Declare new function. (kill_pgrp): Declare. * winsup.h: Move some signal-specific stuff to sigproc.h. * include/cygwin/signal.h: Tweak some siginfo_t stuff. --- winsup/cygwin/dcrt0.cc | 16 ++++++++++++---- 1 file changed, 12 insertions(+), 4 deletions(-) (limited to 'winsup/cygwin/dcrt0.cc') diff --git a/winsup/cygwin/dcrt0.cc b/winsup/cygwin/dcrt0.cc index 3d6b7a89b..29d11f8e4 100644 --- a/winsup/cygwin/dcrt0.cc +++ b/winsup/cygwin/dcrt0.cc @@ -542,8 +542,12 @@ initial_env () buf[0] = '\0'; len = GetModuleFileName (NULL, buf, CYG_MAX_PATH); console_printf ("Sleeping %d, pid %u %s\n", ms, GetCurrentProcessId (), buf); - while (ms--) - Sleep (1); + Sleep (ms); + if (!strace.active) + { + strace.inited = 0; + strace.hello (); + } } if (GetEnvironmentVariable ("CYGWIN_DEBUG", buf, sizeof (buf) - 1)) { @@ -573,7 +577,6 @@ void __stdcall dll_crt0_0 () { wincap.init (); - initial_env (); char zeros[sizeof (child_proc_info->zero)] = {0}; @@ -719,6 +722,7 @@ dll_crt0_1 (char *) /* FIXME: Verify forked children get their exception handler set up ok. */ exception_list cygwin_except_entry; + initial_env (); check_sanity_and_sync (user_data); malloc_init (); @@ -1042,9 +1046,13 @@ do_exit (int status) /* Kill orphaned children on group leader exit */ if (myself->has_pgid_children && myself->pid == myself->pgid) { + siginfo_t si; + si.si_signo = -SIGHUP; + si.si_code = SI_KERNEL; + si.si_pid = si.si_uid = si.si_errno = 0; sigproc_printf ("%d == pgrp %d, send SIG{HUP,CONT} to stopped children", myself->pid, myself->pgid); - kill_pgrp (myself->pgid, -SIGHUP); + kill_pgrp (myself->pgid, si); } } -- cgit v1.2.3
