2012-06-19Revert errneous checkin.Christopher Faylor
Check in actual change associated with ChangeLog.
2012-06-19* cygwait.cc (cancelable_wait): Mimic old cygwait behavior more closely wrtChristopher Faylor
handling of call_signal_handler. * cygwait.h (WAIT_CANCELED): Move here and redefine. (WAIT_SIGNALED): Ditto. * thread.h (WAIT_CANCELED): Delete. (WAIT_SIGNALED): Ditto.
2012-05-02* ChangeNotes: New file. Add entry cgf-000001.Christopher Faylor
* sigproc.cc (proc_terminate): Don't set parent pid of child to 1 if we've execed since the execed process is still considered the parent. * child_info.h: Bump copyright.
2012-04-30* fhandler.h (PIPE_ADD_PID): Define new flag.Christopher Faylor
* pipe.cc (fhandler_pipe::create): Don't indiscriminately add process id to every pipe since some pipe names (fifo, tty) don't need it. * sigproc.cc (sigproc_init): Pass PIPE_ADD_PID to fhandler_pipe::create to ensure that pid is always part of sigwait pipe name.
2012-04-28* environ.cc (struct parse_thing): Add temporary (?) "pipe_byte" option.Christopher Faylor
* globals.cc (pipe_byte): Declare. * pipe.cc (fhandler_pipe::create): Use current process id in pipe name rather than pid for simple name collision avoidance. Do this only once to avoid extra overhead when a busy pipe is found. Honor pipe_byte to create non-message pipes if set. * sigproc.cc (sigproc_init): Use a specific name for the signal pipe.
2012-03-28* sigproc.cc (proc_terminate): Avoid releasing myself.Christopher Faylor
2012-03-21* child_info.h (child_info::postfork): Define new function.Christopher Faylor
* fork.cc (frok::parent): Call postfork to do all of the manipulation required prior to calling pinfo::remember. * pinfo.h (pinfo::set_rd_proc_pipe): Just set pinfo's rd_proc_pipe. Don't bother setting it to NULL. * sigproc.cc (child_info_spawn::wait_for_myself): Call postfork to set up myself for waiting. * spawn.cc (child_info_spawn::worker): Avoid now-unnecessary global lock. Consistently test mode rather than chtype when making wr_proc_pipe decisions. Call postfork() to set up stuff prior to pinfo::remember.

(child_info_spawn::wait_for_myself): Move function to sigproc.cc. * pinfo.cc (is_toplevel_proc): Delete unneeded variable. * sigproc.cc (child_info_spawn::wait_for_myself): Move function from header to here. Do all setup required to properly wait for top-level execed process to exit. * spawn.cc (child_info_spawn::worker): Attempt to properly handle _P_DETACH. Set wr_proc_pipe if top-level process even when execing. Just call wait_for_myself() to... wait for myself. Don't call cleanup twice.
