(attach_process): Don't complain if given a windows process. Use windows pid in error. (handle_output_debug_string): Issue error if trying to manipulate a process that we don't know about. Handle _STRACE_CHILD_PID - attach to reported child when we get this. (proc_child): Move nprocesses to file scope. Report on exceptions. (longopts): Implement "--quiet". (opts): Implement "-q". (main): Manipulate quiet flag. * utils.sgml (strace): Add words describing '-q'.
* * spawn.cc (spawn_guts): Hide the window whenever ctty == -1, not just when weChristopher Faylor2005-12-211-1/+1

* * cygheap.cc (init_cygheap::manage_console_count): Revert previous change.Christopher Faylor2005-12-211-3/+11
| | | | | | | | | | | | | Handle this a different way. * external.cc (cygwin_internal): Accommodate extra hook_or_detect_cygwin argument. * hookapi.cc (cygwin_internal): Fill in subsys variable with the subsystem of the executable. * spawn.cc (av::iscui): New variable. (spawn_guts): Hide window when we don't have a console and this isn't NT/XP/2003. (av::fixup): Set iscui flag. * winsup.h (hook_or_detect_cygwin): Accommodate extra argument.
* * fhandler.h (set_console_state_for_spawn): Add an argument to the declaration.Christopher Faylor2005-12-191-2/+1
| | | | | | | | * fhandler_console.cc (set_console_state_for_spawn): Ditto for the definition. Only set invisible console for non-cygwin process. Remove debugging leftover. * spawn.cc (spawn_guts): Pass argument denoting whether this is a cygwin process to set_console_state_for_spawn and only call this function when exec'ing.
* * fhandler.h (fhandler_pipe::fixup_in_child): Declare new function.Christopher Faylor2005-12-191-11/+16
| | | | | | | | | | | | | | | | | | | | | | (fhandler_console::invisible_console): Declare new variable. (fhandler_console::need_invisible): Ditto. (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.
* * exceptions.cc (signal_exit): Eliminate setting of main thread priority sinceChristopher Faylor2005-10-291-1/+3
| | | | | | | | process lock should make that unnecessary. * fork.cc (stack_base): Eliminate. (frok::parent): Subsume stack_base and just set stack stuff here. Report on priority class in debugging output. * spawn.cc (spawn_guts): Report on priority class in debugging output.
