(fhandler_console::has_a): Ditto. * fhandler_console.cc (set_console_state_for_spawn): Eliminate return value. Set up an invisible console if necessary prior to spawning. (fhandler_console::invisible_console): Define. * fhandler_tty.cc (fhandler_tty_slave::open): Use fhandler_console::invisible_console to setup an invisible console. * pipe.cc (fhandler_pipe::fixup_in_child): Define new function from fixup_after_exec. (fhandler_pipe::fixup_after_exec): Use fixup_in_child when appropriate. (fhandler_pipe::fixup_after_fork): Ditto. * spawn.cc (handle): Reorganize and modernize a little. (spawn_guts): Rely on set_console_state_for_spawn to set the console into the right state but don't create the process with "detached" flag if we have no controlling tty since that confuses 'cmd'. * dtable.cc (dtable::stdio_init): Don't set console as controlling terminal if we have an invisible console. * sigproc.cc (child_info::sync): Use correct name in ForceCloseHandle1.
2005-12-13* cygtls.cc (_cygtls::remove): Don't bother if we're exiting.Christopher Faylor
* sigproc.cc (_cygtls::remove_wq): Ditto.
2005-12-03* cygtls.h (_cygtls::el): New field.Christopher Faylor
(_cygtls::handle_exceptions): New function declaration. (_cygtls::handle_threadlist_exception): Ditto. (_cygtls::init_exception_handler): Ditto. (_cygtls::init_threadlist_exceptions): Remove arg from declaration. * cygtls.cc (_cygtls::call2): Don't initialize exceptions here. (_cygtls::init_thread): Do it here instead and use member function. (_cygtls::handle_threadlist_exception): Move into _cygtls class. (_cygtls::init_exception_handler): Ditto. Rely on existence of 'el' memmber in _cygtls. (_cygtls::init_threadlist_exceptions): Ditto. * dcrt0.cc (dll_crt0_1): Remove exception_list definition and setting since it now commonly resides in the tls. * exceptions.cc (init_exception_handler): Move to cygtls.cc. (init_exceptions): Ditto. (rtl_unwind): New, safe wrapper function for RtlUnwind. (_cygtls::handle_exceptions): Move to _cygtls. Call rtl_unwind to unwind frames and eliminate copying of structures. Put address of failing instruction in si_addr, not the address on the stack. Return 0 to indicate that we've handled this exception. * external.cc (cygwin_internal): Make CW_INIT_EXCEPTIONS a no-op. * sigproc.cc (wait_sig): Accommodate argument change to _cygtls::init_threadlist_exceptions. * tlsoffsets.h: Regenerate. * include/exceptions.h (exception_list): Add more stuff to the exception list. Apparently windows needs this? (init_exceptions): Remove bogus declaration. * include/cygwin/signal.h (SI_USER): Redefine as zero as per SUSv3. * thread.cc (pthread_kill): Set si_pid and si_uid. * timer.cc (timer_thread): Set si_code to SI_TIMER.
2005-10-29* fork.cc (frok::child): Change order of cleanup prior to return.Christopher Faylor
(fork): Save more of the stack. * gendef: Fix some comments. * sigproc.cc (wait_sig): Clarify debug output.
