This minimizes a race between a child which - is exiting at nearly the same time as its parent. - * sigproc.cc: Reformat function calls. - (sigproc_init): Clear new PID_INITIALIZING flag to indicate that - a (possibly execed) process is now capable of receiving signals. - (sig_send): Be more defensive in determining if a signal can be - sent to myself or suffer problems with execed processes. - (sigproc_terminate): Wait for sig_proc to exit to ensure that - all pending signals have been handled. Use new 'proc_terminate' - function to terminate the subprocess handling thread. - (allow_sig_dispatch): Don't bother blocking signals if signal - handling isn't active in this process yet. - (block_sig_dispatch): Don't bother blocking signals if signal - handling isn't active in this process yet. - (sig_proc): Use sig_loop_wait variable to control wait time for - signal semaphores. Uncouples this wait from wait_subproc. - Perform signal cleanup here on thread termination. - (proc_exists): More accurate tests to determine if a process - really exists. - (proc_register): Remove this function in favor of a macro. - (proc_subproc): More stringent test for being "ready" to process - subprocesses. Add more common initialization to PROC_ADDCHILD. - Remove PROC_EXIT in favor of a separate function. - (proc_terminate): New function. Replaces PROC_EXIT functionality - in proc_subproc. Terminates subproc handler thread. - (stopped_or_terminated): use lock_pinfo_for_update when modifying - child stopsig status or suffer a race. - (wait_subproc): Save sig_proc thread handle away for - synchronization when exiting. Set up 'i_am_alive' mutex inherited - by childen. Child's inability to lock this mutex means that the - parent is still alive and processing children. Use proc_loop_wait - to control WFMO. Clean up events queue on thread exit. - (zap_subproc): Clear out pinfo structure for a child. - * sigproc.h: Remove PROC_EXIT constant. Remove obsolete - proc_register declaration. - (alive_parent): New macro to determine if a parent is still alive. - * spawn.cc (spawn_guts): Fix a comment typo. Use proc_terminate - to terminate all subprocess handling prior to an exec. Use new - method for determining if this process was started via a fork. - Attempt to clean up races between execed process, its parent, and - the execed child. - * winsup.h (pinfo): Add a new handle indicating that a parent is - alive. This should be a foolproof way of determining if a parent - has gone away so that a child will know whether to remove itself - from the pinfo table. - Reorganize the structure in such a way that items to be zeroed - are grouped together at the beginning for more efficient zeroing - in allocate_pid. - Add a new PID_* constant. - New lock_pinfo_for_update macro for use when debugging cygwin. - -Wed Dec 10 00:05:23 1997 Geoffrey Noer <noer@cygnus.com> - - patch from sos@prospect.com.ru (Sergey Okhapkin): - Change the way to inherit fd table on spawn/exec calls. - Use STARTUPINFO structure to pass an fd table to a child process - instead of shared memory area. This is undocumented, but is used - by MSVC runtime. The desktop inheritance code added again, - otherwise user32.dll will fail to initialize after sexec calls. - * pinfo.cc (pinfo_init): delinearize fd array from STARTUPINFO - structure instead of call to copy_shared_fd_table. - * shared.cc (create_shared_fd_mapping_name): remove - (create/copy_shared_fd_table): remove - * spawn.cc (spawn_guts): use lp(cb)Reserved2 fields of STARTUPINFO - to pass fd table to a child. Remove call to - create_shared_fd_table. Inherit window station/desktop on sexec - calls. - * winsup.h: remove prototypes for create/copy_shared_fd_table. - -Fri Dec 5 18:57:42 1997 Geoffrey Noer <noer@cygnus.com> - - patch from cgf@bbc.com (Chris Faylor): - * kill.cc (main): Report error if kill() fails. Minor reformat. - * ps.cc (main): Only use month/day in start time when starting - time is > 24 hours in the past, not when it occurs yesterday. - -Fri Dec 5 15:54:41 1997 Geoffrey Noer <noer@cygnus.com> - - * fcntl.cc (_fcntl): reformat - * fhandler.cc (fhandler_tty::open): new, need special open for - ttys. In addition to calling fhandler_base::open, check - flags to handle blocking vs. non-blocking I/O. Should - initialize tty to standard state (9600 bits/sec - 8 - 1 with - no flow control) but this code needs more work still. Ifdef - out for now. - (fhandler_tty::tcsendbreak): new - (fhandler_tty::tcdrain): new - (fhandler_tty::tcflow): new - (fhandler_tty::tcsetattr): add support for action arg. Use - a DCB struct to hold the values we will set. First call - GetCommState to get the current state, then reassign values - based on the contents of the termios struct. Handle the - case where t->c_ospeed is set to B0, otherwise set state.BaudRate. - Set all the other DCB struct values appropriately, based on - the contents of the termios struct. - (fhandler_tty::tcgetattr): do the inverse of tcsetattr. - Call GetCommState to get the current state and use this to set - the appropriate termios struct values. - * termios.cc: reformat - (tcsendbreak): implement -- add duration arg, - call fhandler tcsendbreak as appropriate - (tcdrain): implement -- call fhandler tcdrain as appropriate - (tcflow): implement -- call fhandler tcflow as appropriate - * fhandler.h: add new tc* protos - * include/sys/termios.h: correct values of iflag bits, - define CRTSXOFF and CRTSCTS, CBAUD, B57600 and B115200. - Add protos for tc* functions. - -Wed Nov 26 17:06:17 1997 Geoffrey Noer <noer@cygnus.com> - - patch from sos@prospect.com.ru (Sergey Okhapkin): - * spawn.cc (perhaps_suffix): resolve symlinks to .exes. - -Mon Nov 24 17:10:49 1997 Geoffrey Noer <noer@cygnus.com> - - * cygwin.din: remove crypt - * syscalls.cc (crypt): remove crypt stub - -Sun Nov 23 17:34:42 1997 Geoffrey Noer <noer@cygnus.com> - - patch from sos@prospect.com.ru (Sergey Okhapkin): - * spawn.cc (spawn_guts): save the path of the script itself, - use the saved path while building the command line to execute. - -Thu Nov 20 22:58:23 1997 Geoffrey Noer <noer@cygnus.com> - - * stubs.cc: delete file, move unimplemented stubs to the - files in which they would normally belong. - * grp.cc (setgrent): implement (was in stubs.cc) - * syscalls.cc: move regfree, mknod, setgid, set(e)uid, sync, - crypt, and PPC __chkstk/_alloca/dll_entry stubs here from stubs.cc - (sync): just return zero for now instead of -1 - (crypt): return -1 instead of 0 - -Thu Nov 20 22:41:57 1997 Geoffrey Noer <noer@cygnus.com> - - patch from cgf@bbc.com (Chris Faylor): - * spawn.cc (spawn_guts): A premature close of the spawned filehandle - was possible when reparenting an exited process.

Before this - change, executing "set CYGWIN_TTY=1", "bash", "unset CYGWIN_TTY", - "/bin/pwd" would result in pwd printing nothing because - the de_linearize code would use the wrong fhandler_xxx when - reading from the buffer inherited from the parent process. - * cygwin.din: Add new ctermid function for export. - * syscalls.cc (ctermid): New function - * exceptions.cc (call_handler): If called during a P_OVERLAY - spawn, merely set appropriate flags and return. The spawn - code will then clean up and exit. - * sigproc.cc (proc_exists): Reorganize to better detect defunct - processes. Don't clean up pinfo if process has a parent since the - parent should clean up eventually. - * spawn.cc: New global exec_exit. Set by signal handler to - value which should be used on exit from aborted spawn. - (spawn_guts): Try harder to let the child terminate (if it is - going to) before exiting on a signal. Remove obsolete code. - - patch from sos@prospect.com.ru (Sergey Okhapkin): - * exec.cc (file_exists): Removed - * spawn.cc (spawn_guts): call perhaps_suffix to convert filename - to win32 form and to check file existance; prog variable - removed, all references changed to real_path variable. - Do not inherit parent's window station/desktop on sexecXX calls. - They are no longer needed with the new signal handling. - (_spawnve): extra file existance check removed - * winsup.h: file_exists prototype removed - -Wed Nov 19 16:23:47 1997 Geoffrey Noer <noer@cygnus.com> - - patch from sos@prospect.com.ru (Sergey Okhapkin): - * cygwin.din: add missing exports for random -- initstate - and setstate (accessed by gawk among others?) - -Tue Nov 18 22:27:10 1997 Geoffrey Noer <noer@cygnus.com> - - * Makefile.in: Add spaces after colons in rules for make - -Mon Nov 17 22:35:25 1997 Geoffrey Noer <noer@cygnus.com> - - patch from proven@cygnus.com (Chris Provenzano): - * Makefile.in: set SHELL = @SHELL@, set VPATH to only @srcdir@. - Remove mingw from directories to build for now, adapt rules - for building sysdef files without fancy VPATH - * configure: regenerate - * config/i386/makefrag: add rules to build setjmp/longjmp - * regexp/Makefile.in: set SHELL = @SHELL@ - * regexp/configure: regenerate - * utils/Makefile.in: set SHELL = @SHELL@ - * utils/configure: regenerate - -Mon Nov 17 18:36:50 1997 Geoffrey Noer <noer@rtl.cygnus.com> - - patch from sos@prospect.com.ru (Sergey Okhapkin): - * fhandler.cc (fhandler_disk_file::open): calls to symlink_XXX - replaced with path_conv class calls. - * path.cc (path_conv::path_conv): comments added, O_NOSYMLINK case - added. - * path.h (class path_conv): symlink_p, exec_p - new class members. - * spawn.cc (spawn_guts): call path_conv instead of symlink_follow. - -Sun Nov 16 15:54:27 1997 Geoffrey Noer <noer@rtl.cygnus.com> - - patch from cgf@bbc.com (Chris Faylor): - * dcrt0.cc (do_exit): Use new pinfo element in debug statement. - * pinfo.cc (pinfo_init): Eliminate use of "PID" environment - variable in favor of scanning the process table for a - SpawnedProcessId field matching current windows process id. - Should speed up spawned process startup slightly. Delay setting - of dwProcessId until process is capable of processing signals - since this field is used to build signal semaphores. - * signal.cc (kill_worker): Perform a `proc_exists' on the pid - in question if signal == 0. This will verify that the process - actually exists and was not abnormally terminated. - * sigproc.cc (sigproc_init): Initialize dwProcessId field after - signal processing has been initialized. - (sigproc_terminate): Remove events[0] close. - (getsem): Use GetCurrentProcessId to find the windows pid since - this dwProcessId field is not yet set up. Use proc_exists to - determine if error should be printed on OpenSemaphore error. - (proc_exists): New function. Makes more exhaustive test of - process existence. Determines if process died without going - through normal shutdown. - (wait_subproc): Close wakeup event only on thread exit. - * spawn.cc: Remove pExeced. Use new field in pinfo. - (spawn_guts): Initialize dwSpawnedProcessId field. - * utils/ps.cc (main): Perform a kill(pid, 0) on any pids that - appear to be active. This will clear out pids that have died - abnormally. 'ps -f' bypasses this. - * winsup.h (class pinfo): Add dwSpawnedProcessId field. - -Sun Nov 16 15:54:27 1997 Geoffrey Noer <noer@rtl.cygnus.com> - - patch from sos@prospect.com.ru (Sergey Okhapkin): - * pinfo.cc ((pinfo_init): use dwProcessId for execed/spawned - check, set subproc_ready event only if the process is exec'ed. - * spawn.cc (spawn_guts): initialize hProcess and dwProcessId - fields of pinfo on exec, keep progname field on spawn. - -Sun Nov 16 15:54:27 1997 Geoffrey Noer <noer@rtl.cygnus.com> - - patch from sos@prospect.com.ru (Sergey Okhapkin): - * dcrt0.cc: remove commented out code - * spawn.cc: fix misapplied patch problem - -Sun Nov 16 15:54:27 1997 Geoffrey Noer <noer@cygnus.com> - - patch from cgf@bbc.com (Chris Faylor): - * fhandler.cc (fhandler_dev_null::open): Open Windows 'nul' - device rather than "faking" a real open. - (fhandler_dev_null::close): delete. - (fhandler_dev_null::fstat): delete. - (fhandler_dev_null::ioctl): delete. - (fhandler_dev_null::read): delete. - (fhandler_dev_null::write): delete. - (fhandler_dev_null::lseek): delete. - (fhandler_dev_null::dup): delete. - * fhandler.h (class fhandler_base): delete above methods from - class. - * hinfo.cc (hinfo_vec::build_fhandler): Use new fhandler_dev_null - class which opens 'nul' device. Treat /dev/null similarly to - other Windows devices. This allows redirection of /dev/null to - non-cygwin processes. - -Sun Nov 16 15:54:27 1997 Geoffrey Noer <noer@cygnus.com> - - patch from cgf@bbc.com (Chris Faylor): - * dcrt0.cc (do_exit): Use EXIT_* flags to determine how exit - should proceed. Honor new EXIT_NOCLOSEALL to avoid - close_all_files. - * exceptions.cc (__cygwin32_exception_handler): Use new - EXIT_SIGNAL define to indicate exiting due to signal. - * signal.cc (sigprocmask): Slightly more defensive check against - being called prior to complete cygwin setup. - (_raise): Defensive check to guard against being called prior to - complete cygwin setup. - * sigproc.cc (stopped_or_terminated): Use new EXIT_SIGNAL define - to detect exiting due to signal. - * sigproc.h: Define flags to be used during exit process as - EXIT_*. - * spawn.cc (spawn_guts): Use EXIT_* constants to control how - do_exit proceeds after _P_OVERLAY. - -Sun Nov 16 15:54:27 1997 Geoffrey Noer <noer@cygnus.com> - - * sysconf.cc (sysconf): return 1048576 for ARG_MAX until - we figure out the right value (_POSIX_ARG_MAX is only 4K - which is too small). - -Sun Nov 16 15:54:27 1997 Geoffrey Noer <noer@cygnus.com> - - patch from sos@prospect.com.ru (Sergey Okhapkin): - * dcrt0.cc (dll_crt0_1): call winsock_init if neccesary. - * fhandler.cc ((fhandler_socket::fhandler_socket): moved to net.cc - * fhandler.h (class fhandler_socket): destructor prototype added. - * fork.cc (cygwin_fork_helper1): set PID_SOCKETS_USED in the - child's pinfo if parent has open socket descriptors; call - winsock_init in child code if necessary. - * net.cc: static variable winsock_init_p removed; - number_of_sockets is new global variable containing number of - opened sockets. - (winsock_init): made global, save "winsock inited" flag in process - state field. - (cygwin32_winsock calls): condition for winsock initialisation - changed - (fhandler_socket::fhandler_socket): new, moved from fhandler.cc; - increment number_of_sockets on constructor call. - (fhandler_socket::~fhandler_socket): new. Decrement - number_of_sockets on destructor call, check for negative value. - (fhandler_socket::ioctl): check for winsock initialisation added. - * spawn.cc (spawn_guts): handle PID_SOCKETS_USED in child's pinfo. - * winsup.h: PID_SOCKETS_USED - new enum value; number_of_sockets - and winsock_init() prototypes added. - -Wed Nov 12 23:02:34 1997 Geoffrey Noer <noer@cygnus.com> - - patch from cgf@bbc.com (Chris Faylor): - * exceptions.cc: Substitute do_exit for _exit as appropriate. - do_exit allows full 32 bits of exit value. The upper 16 bits - are used for special cygwin operations. - * winsup.h: Change definition of do_exit to allow calling from - signal handler. - * dcrt0.cc (do_exit): Change to allow calling from signal handler - in place of _exit. This is necessary to ensure that only cygwin - internal applications can exit with the upper order 16 bits set - to non-zero. - -Wed Nov 12 23:02:34 1997 Geoffrey Noer <noer@cygnus.com> - - patch from cgf@bbc.com (Chris Faylor): - * dcrt0.cc (do_exit): New function. Subsumes functionality of - _exit but takes a DWORD argument. Changed to avoid some shutdown - activities when called with REPARENTING bit set in argument. Also - explicitly kills any executing non-cygwin subprocess from a - spawn(P_OVERLAY)... - (_exit): Use do_exit for exiting. Ensure that only low order 1 - bits of status are used or confusion will result if exiting with - some higher order bits set. - * exceptions.cc (set_process_mask): Reflect new method for - sig_send to send signals to self. - (handle_sigsuspend): Reflect new method for sig_send to send - signals to self. - * fork.cc: A handle name was changed in the pinfo structure to - be more reflective of its use. Change forkee_stopped to - subproc_ready everywhere. - * pinfo.cc (pinfo::clearout): Change forkee_stopped to - subproc_ready. - (pinfo_init): Use PID_EXECED flag to determine if this process has - been execed. If so, signal the remaining stub in the process - which invoked us so that the stub can terminate and let us take - over as this pid. - * sigproc.cc (sig_send): Change method for determining if sending - signals to myself. A NULL pointer means communicate with my - signal handler. This is necessary to allow communication with - our own signal processors after reparenting an execed process. - Also, add an additional test to detect if a process goes away in - the middle of attempting to send it a signal. - (allow_sig_dispatch): Reflect new method for sig_send to send - signals to self. - (getsem): Use dwProcessId in names for signal semaphores. Allows - communicating with both parts of a process that is temporarily - "split in two" while execing. - (sig_proc): Avoid printing an error if WAIT_FAILED and exiting - anyway. Process requests even if loop_wait == 0. - (proc_subproc): Defensive check for manipulating processes prior - to initialization or after terminating sigproc. - Use different check for subprocesses that have been reparented. - Hopefully this will eliminate WFSO, error 6 problems. - (wait_subproc): Only exit when loop_wait == 0 and not dealing with - a process. - * spawn.cc: Set up two global variables, used on exit when - execing a non-cygwin process: hExeced - handle of non-cygwin - process which is being waited for by a stub, pExeced - windows pid - of the process. - (spawn_guts): Reorganize to always (temporarily) wait for the new - process when P_OVERLAY. If a cygwin process is invoked, then the - wait will return when an event is signalled and the new process - will be "reparented" in the ppid. If a non-cygwin process is - invoked, wait until the process exits or a signal is received - which terminates the process.
