From 67483cb2cdee37aa435fd108cea5310a873925a3 Mon Sep 17 00:00:00 2001 From: Christopher Faylor Date: Tue, 13 Sep 2005 17:08:54 +0000 Subject: * dcrt0.cc (do_exit): Rely on sigproc_terminate to set exit_state appropriately. * pinfo.cc (pinfo::exit): Always call sigproc_terminate here. Rely on sigproc_terminate to signal signal thread to handle eventual process exit. * sigproc.cc (no_signals_available): Change criteria for determining if this process can handle signals to itself. (my_sendsig): New variable. Copy of my sendsig handle. (proc_can_be_signalled): Don't send signals if exit code is set. (sigproc_terminate): Use and set exit_state appropriately to determine when to do anything. Send __SIGEXIT to self to control process exit. (sig_send): Use my_sendsig for sending signals. Don't call proc_can_be_signalled for myself since the criteria is now different for sending signals to myself. (wait_sig): Copy myself->sendsig to my_sendsig for future use. Exit signal loop when __SIGEXIT is received. Wait for main thread to exit and use its exit status to actually exit process. * sigproc.h (__SIGEXIT): New enum. * dcrt0.cc (alloc_stack): Eliminate superfluous "return;". * debug.cc (add_handle): Ditto. * devices.in (device::parse): Ditto. * dtable.cc (dtable::vfork_parent_restore): Ditto. (dtable::vfork_child_fixup): Ditto. * environ.cc (parse_options): Ditto. * errno.cc (seterrno_from_win_error): Ditto. * exceptions.cc (sig_handle_tty_stop): Ditto. (set_signal_mask): Ditto. * fhandler.cc (fhandler_base::read): Ditto. (fhandler_base::operator delete): Ditto. (fhandler_base::seekdir): Ditto. (fhandler_base::rewinddir): Ditto. * fhandler_console.cc (fhandler_console::read): Ditto. (fhandler_console::fixup_after_exec): Ditto. * sigproc.cc (sigproc_init): Ditto. (sigproc_terminate): Ditto. * devices.cc: Regenerate. --- winsup/cygwin/fhandler.cc | 4 ---- 1 file changed, 4 deletions(-) (limited to 'winsup/cygwin/fhandler.cc') diff --git a/winsup/cygwin/fhandler.cc b/winsup/cygwin/fhandler.cc index 63ca99b4a..a8a27862a 100644 --- a/winsup/cygwin/fhandler.cc +++ b/winsup/cygwin/fhandler.cc @@ -789,7 +789,6 @@ fhandler_base::read (void *in_ptr, size_t& len) out: debug_printf ("returning %d, %s mode", len, rbinary () ?
