(pinfo::init): Accommodate case where myself.h is known but h0 is passed in. (pinfo::pinfo): New constructor for setting up a pinfo passed in by previous exec'or. (pinfo::proc_waiter): Don't handle subprocess if we're in the process of exiting due to an exec of a cygwin process. Don't close rd_proc_pipe here. Close it when we actually are finished with the process. Use new ch_spawn.signal_myself_exited function to let exec stub know that subprocess has exited. (pinfo::wait): Clarify debugging output. (pinfo::release): Use "close_h" to close all handles to avoid races. (winpids::add): Assume that elements of the array do not need to be zeroed and are properly initialized or suffer problems on pinfo::release. Don't close hProcess since release does that now. * pinfo.h: Update comment. (pinfo_minimal): Move some elements from pinfo here so that child_info_spawn can use them. (pinfo): Inherit from pinfo_minimal. (pinfo::pinfo): Modify to accommodate new pinfo_minimal. (pinfo::allow_remove): New function. * sigproc.cc (proc_subproc): Use boolean values for true/false. Implement PROC_EXEC_CLEANUP. (proc_terminate): Set ppid = 1 since the procs list will only be iterated when the process has not execed. Don't do any cleanup here since it is now handled in pinfo::release. (sigproc_init): Initialize sync_proc_subproc earlier. (child_info::child_info): Assume that all important fields are properly initialized and avoid memset(). (child_info_spawn::child_info_spawn): Specifically test for execing and then set up appropriate fields in the struct. (child_info_spawn::cleanup): Define new function. (child_info_spawn::record_children): Specifically test for being execed here. Fill in pinfo_minimal part of children array. (child_info_spawn::reattach_children): Use constructor to duplicate information for previous exec'or. Add more debugging output. (remove_proc): Force deletion of thread when exiting due to exec. Rely on pinfo::cleanup in release. * sigproc.h (PROC_EXEC_CLEANUP): New enum. (PROC_DETACHED_CHILD): Delete. * spawn.cc (chExeced): Delete. (child_info_spawn::worker): Rename from spawn_guts. Use elements of child_info_spawn throughout rather than ch.whatever. Use ::cygheap to refer to global rather than element of child_info. Use wait_for_myself() rather than waitpid(). Call child_info_spawn::cleanup on function return. (spawnve): Reflect movement of spawn_guts functionality into child_info_spawn::worker. * syscalls.cc (popen): Ditto. * winsup.h (spawn_guts): Delete declaration.
* * child_info.h (cchildren): New struct.Christopher Faylor2011-10-261-0/+2

(child_info_spawn::reattach_children): Ditto. * dcrt0.cc (child_info_spawn::handle_spawn): Call reattach_children to gather list of processes we are potentially waiting for. * pinfo.h (pinfo::pinfo): Make sure that rd_proc_pipe is always cleared. (pinfo::reattach): New function. * sigproc.cc: Move pinfo.h earlier so that it can be used in sigproc.h. (get_proc_lock): Don't bother with a lock during DLL initialization. (proc_subproc): Handle PROC_REATTACH_CHILD. (proc_terminate): Orphan children only when we are not an execed process or when the pid is about to be occupied by a non-cygwin process. (child_info_spawn::record_children): Define new function. (child_info_spawn::reattach_children): Ditto. * sigproc.h (procstuff): Define PROC_REATTACH_CHILD and renumber other elements. * spawn.cc (spawn_guts): Record any to-be-waited-for subprocesses if about to exec a cygwin process. * sigproc.cc (sig_send): Fix harmless transposition of fifth and six arguments to DuplicateHandle(). (child_info::child_info): Ditto. * globals.cc (hExeced): Make NO_COPY.
* * hookapi.cc (hook_or_detect_cygwin): Take additional handleCorinna Vinschen2011-10-251-6/+24
| | | | | | | | | to a file mapping as parameter. If this handle is not NULL, create another file mapping for the IAT. * spawn.cc (av::fixup): Only map the first 64K of an image and keep the mapping handle to use as argument to hook_or_detect_cygwin. * winsup.h (hook_or_detect_cygwin): Add mapping handle as default parameter in declaration.
* Throughout change TTY_* to PTY_*, tty_* to pty_*, and ttym_* to ptmx_*.Christopher Faylor2011-10-201-2/+2
| | | | | | | | | | | | | | | | * devices.cc: Regenerate. * dtable.cc: (fh_alloc): Preserve /dev/tty name when that's what we opened.

(path_conv::operator =): Free any allocated strings in target. (path_conv::free_strings): Delete unused function. * sigproc.cc (proc_terminate): Remove previous accommodation for execed processes since it didn't have the desired effect. Change comment to a FIXME. * spawn.cc (chExeced): Mark NO_COPY. (exe_suffixes): Ditto.
* * fhandler.h (fhandler_console::tc_getpgid): New function.Christopher Faylor2011-10-071-1/+11
| | | | | * spawn.cc (spawn_guts): Add logic to put pure-windows processes "in the background" when they are started that way.
* Throughout, open console handles with sharing for reading and writing.Corinna Vinschen2011-07-041-1/+1
