state if we know we're starting a cygwin process or if we're using a "real"
tty.
2006-01-12 05:03:15 +00:00
Christopher Faylor 5da5f949d8 * spawn.cc (spawn_guts): Reorganize slightly so that 16 bit check is done prior
to check for command.com/cmd.com.  Don't bother setting CREATE_SUSPENDED flag
for a MS-DOS process since it doesn't work anyway.  Avoid calling remember()
when the child process has already exited.
(av::fixup): Explicitly set cygexec flag to falseon a 16 bit process.
2006-01-10 02:39:22 +00:00
Christopher Faylor 85c804ec4b * fhandler.h (set_console_state_for_spawn): Eliminate argument from
declaration.
* fhandler.cc (set_console_state_for_spawn): Eliminate argument from
definition.  Always check for invisible console.
(fhandler_console::need_invisible): Don't do anything if the windows station is
already not visible.
* spawn.cc (spawn_guts): Accommodate change of argument to
set_console_state_for_spawn.
2006-01-07 17:57:26 +00:00
Christopher Faylor 32f0697595 * cygtls.cc (_cygtls::remove): Don't output debugging info if this isn't a
cygwin thread.
2006-01-05 16:23:19 +00:00
Christopher Faylor 4c15746236 * fhandler_process.cc (fhandler_process::readdir): Add missing argument to
syscall_printf.
* fhandler_console.cc (fhandler_console::need_invisible): Use made-up name for
windows station rather than asking Windows to create one for us.
* spawn.cc (spawn_guts): Don't mess with console if we're detaching.

Christopher Faylor 5d97040501 *** cygwin DLL Changes:
* child_info.h (CURR_CHILD_INFO_MAGIC): Reset.
(child_info::dwProcessId): Delete.
(child_info::straced): New variable.
(child_info::handle_fork): New member function.
* dcrt0.cc (in_forkee): New global variable.
(__cygwin_user_data::forkee): Mark as obsolete.
(do_global_ctors): Use in_forkee rather than user_data->forkee.
(get_cygwin_startup_info): Ditto.  Deal with new straced field to allow strace
to deal with children of attached processes.
(initial_env): Accommodate changes to strace::hello.
(child_info_fork::handle_fork): Rename from plain old 'handle_fork'.  Move
alloc_stack() call elsewhere.
(dll_crt0_0): Fill out more of user_data.  Reference handle_fork via fork_info.
Add some debugging output.
(_dll_crt0): Don't wait for sync thread if sync_startup is invalid.  Zero
sync_startup here.  Call alloc_stack() here, if appropriate.
(dll_crt0_1): Use in_forkee rather than user_data->forkee.
(dll_crt0): Ditto.
* malloc_wrapper.cc (malloc_init): Ditto.
* dll_init.cc (in_forkee): Remove local static version of this variable.
(dll_list::load_after_fork): Don't set in_forkee here.
* external.cc (cygwin_internal): Use strace method rather than accessing field
directly.
* fhandler.cc (fhandler_base::read): Ditto.
* fhandler_tty.cc (fhandler_tty_common::__acquire_output_mutex): Ditto.
* fork.cc (frok::parent): Invoke strace write_childpid to communicate with
potential strace.
(child_copy): Add more detail to debugging output.
* init.cc (calibration_id): New static variable.
(prime_threads): Set sync_startup to invalid handle if we already know about
thread_func_ix.  Use static calibration_id to hold calibration thread id.
* munge_threadfunc (munge_threadfunc): Don't try to debug if we don't find
threadfunc_ix.
(dll_entry): Avoid calling munge_threadfunc and _cygtls::remove on non-cygwin
threads invoked during process startup.

* sigproc.cc (child_info::child_info): Remove spurious handling of dwProcessId.
Set straced as appropriate.
* spawn.cc (spawn_guts): Rename ciresrv to ch.  Invoke strace write_childpid to
communicate with potential strace.
* strace.cc: Include child_info.h.
(strace::hello): Remove inited test.  Use active() method to test if strace has
been activated.  Handle case where we are started before
(mypid): New function.
(strace::vsprntf): Try to deal more intelligently with case where progname may
not be filled out.  Put pid in parentheses if it is a windows pid rather than a
cygwin pid.  myself has been filled out.
(strace::write_childpid): New function for notifying strace about the creation
of children.
(strace::vprntf): Use strace method rather than accessing field directly.
(strace_printf): Ditto.

(strace_printf_wrap1): Ditto.

*** cygwin utils changes:
* strace.cc (nprocesses): Make static global.
(quiet): New variable.
(strace_active): Ditto.
(add_child): Increment nprocesses here.  Don't add a child if it is already
added (windows bug?).  Report on child if not quiet.
(get_child): Just return NULL if child not found.
(remove_child): Report on child if not quiet.
(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'.
