* * child_info.h (CURR_CHILD_INFO_MAGIC): Update.Christopher Faylor2004-12-241-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | (child_info::parent_wr_proc_pipe): Eliminate. * pinfo.h (_pinfo::alert_parent): Move here from pinfo class. (_pinfo::dup_proc_pipe): New method. (_pinfo::sync_proc_pipe): Ditto. * exceptions.cc (sig_handle_tty_stop): Reflect move of alert_parent. * init.cc (dll_entry): Exit with status one if main process called ExitProcess. * pinfo.cc (set_myself): Remove handling of parent_wr_proc_pipe. (_pinfo::exit): Reflect move of alert_parent. Set procinfo to NULL to flag that we are exiting normally. Always use exitcode when exiting (although this could be a little racy). (pinfo::init): Set default exit to SIGTERM. This will be the exit code reported if process is terminated. (_pinfo::dup_proc_pipe): New function. (pinfo::wait): Duplicate wr_proc_pipe to the right place. Use dup_proc_pipe to move the pipe to the child. (_pinfo::sync_proc_pipe): New function. (_pinfo::alert_parent): Move to _pinfo. Make sure that wr_proc_pipe is ours before using it. * sigproc.cc (child_info::child_info): Remove handling of parent_wr_proc_pipe. * spawn.cc (spawn_guts): Pass our wr_proc_pipe to the child when execing. Ensure that exit code of cygwin process started from windows is correctly set.
* * child_info.h (CURR_CHILD_INFO_MAGIC): Use updated value.Christopher Faylor2004-12-191-1/+1
| | | | | | | * path.cc (path_conv::check): Check the output Win32 path for trailing spaces and dots, not the input path. Disallow all use of foo./bar since consistently getting this right is time consuming. Remove strange test for "unc\" since no one seems to know what it's for.

Save exec_sendsig and exec_dwProcessId in execing _pinfo. Rely on child_info constructor to properly set parent_wr_proc_pipe in ciresrv. Revert to previous determination on whether to start a process in suspended mode. Remove reparenting stuff. Just keep a stub around if starting a non-cygwin process.
