*** 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. * pinfo.cc (set_myself): Always call strace.hello here regardless of DEBUGGING. * 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::wm): Ditto. * winsup.h (in_forkee): Declare. * include/sys/strace.h (strace::write_childpid): Declare new function. (strace::attached): Define new function. (strace::active): Ditto.

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'.
