Christopher Faylor 806e732c01 Rename cancelable_wait -> cygwait throughout.
* DevNotes: Add entry cgf-000015.
* cygwait.h (cygwait): Don't allow an optional PLARGE_INTERGER argument.
2012-08-15 19:07:42 +00:00
Christopher Faylor 879f3ad5ee * cygtls.h (_cygtls::create_signal_arrived): New function.
(_cygtls::set_signal_arrived): Lock creation of signal_arrived.
* cygwait.cc (cancelable_wait): Ignore signal_arrived event if _my_tls 'sig'
element does not exist.

thread has not created it.

Christopher Faylor d239805457 * cygwait.cc (cancelable_wait): Add some debugging-only output.
* exceptions.cc (sig_handle_tty_stop): Make sure that incyg is cleared when
exiting if we have no parent process.  Only wait for signal_arrived.
(sigpacket::process): Make continue_now a bool.  Delay sending signal_arrived
until the end.  Make code more defensive to avoid calling signal handler when
stopped.  Only set signal_arrived when stopped.
* sigproc.cc (sig_hold): Rename from sigCONT.  Make static.
(sig_send): Accommodate sigCONT -> sig_hold rename.
(wait_sig): Ditto.
* sigproc.h (sigCONT): Delete declaration.

print characters.  Change to paranoid to avoid excessive strace output.
* fhandler_tty.cc (fhandler_pty_master::accept_input): Make frequent strace
printf "paranoid" to help cut down on strace output size.
* signal.cc (sigsuspend): Add standard syscall strace output.
(sigpause): Ditto.
(pause): Ditto.
* cygtls.h (_cygtls::reset_signal_arrived): New function.
