Determines if a process exists based on the pid. (proc_exists (_pinfo *p): Use new proc_exists function above. (proc_subproc): Copy pinfo stuff around rather than _pinfo pointers. Try to be careful about releasing shared memory when we don't need it anymore. Remove pinfo locks. (remove_zombies): Remove pinfo memory when zombie is going away. * sigproc.h: Reflect _pinfo/pinfo changes in sigproc.cc. * spawn.cc (spawn_guts): Eliminate pinfo *child argument. Reorganize to only initialize child pinfo after process has been started and we know the windows pid. (_spawnve): Reflect spawn_guts changes. * syscalls.cc (setpgid): Use pinfo constructor to access process info. (getpgid): Ditto. (internal_getlogin): Use _pinfo. * winsup.h: Eliminate pinfo_mutex. Eliminate spawn_guts declaration since it is static now. Reflect set_myself argument change. * include/sys/cygwin.h: Add some PID_* enums to accomodate new pinfo stuff. * include/cygwin/version.h: Update minor version for cygdrive changes below.
* * acconfig.h: Add support for NEWVFORK.Christopher Faylor2000-07-161-1/+1
| | | | | | | | | * config.h.in: Ditto. * configure.in: Add --enable-vfork option. * configure: Regenerate. * dcrt0.cc (quoted): Detect and fix up quoted backslashes. * sigproc.cc (proc_subproc): Correctly name handle of newly added child process to avoid erroneous debugging messages about closing the wrong handle.
* * sigproc.h (sigframe::set): Accept a default frame pointer.Christopher Faylor2000-05-261-1/+1
| | | | * sigproc.cc (sig_send): Use passed in frame pointer, if appropriate.

* * path.cc (mount_info::cygdrive_posix_path): Don't add trailing slash ifChristopher Faylor2000-05-171-12/+34
| | | | | | | | | | | | | | | | | | | | | | | | | referring to something like c:\. * dcrt0.cc (dll_crt0_1): Move uinfo initialization prior to sig_send initialization to give signal thread a chance to finish. * debug.cc (WFSO): Move to sigproc.cc (WFMO): Ditto. * exceptions.cc (interruptible): Allocate slightly more space for directory just for paranoia's sake. (call_handler): Eliminate nonmain argument. Determine if main thread has set a frame pointer and use it if so. (sig_handle): Eliminate nonmain argument. * net.cc: Record frame information in appropriate routines throughout. * select.cc (select): Ditto. * sigproc.cc: Use sigthread structure to record mainthread id throughout. (sig_send): Record frame information for signal handler. (wait_sig): Reflect argument change in sig_handle. (WFSO): Move here and record frame information for signal handler. (WFMO): Ditto. * sigproc.h: Implement new "sigthread" class. Implement "sigframe" class for manipulating signal frame info. * thread.cc (__pthread_kill): Use standard _kill() function rather than calling sig_send directly. * winsup.h: Eliminate ebp element from signal_dispatch class.
* * environ.cc: Add TMPDIR to the list of environment variables which areChristopher Faylor2000-03-251-2/+5
| | | | | | converted to POSIX format. * sigproc.cc (proc_terminate): Don't attempt to delete when a muto pointer is NULL.
* Pipe changes throughout suggested by Eric Fifer <EFifer@sanwaint.com>Christopher Faylor2000-03-151-1/+1
| | | | | | | | | | | | | | | | | | | | | * debug.cc (threadname_init): Pass name of lock as arg 2 of new_muto. * malloc.cc (malloc_init): Ditto. * sigproc.cc (sigproc_init): Ditto. * exceptions.cc (events_init): Ditto. (call_handler): Eliminate special case for hExeced. Report locked thread in debugging output. * fhandler.cc (fhandker_pipe::fhandler_pipe): Propagate device type to base class. * fhandler.h (fhandler_pipe): Ditto. * hinfo.cc (hinfo::build_fhandler): Pass specific type of pipe to constructor. * spawn.cc (spawn_guts): Eliminate dependency on signal when waiting for subprocess. * strace.cc: Remove obsolete #ifdef. * sync.cc (muto::muto): Save the name of the muto. (muto:~muto): Also release the muto. * sync.h: Add a muto name field. * select.cc (peek_pipe): Avoid doing a PeekNamedPipe on the write end of a pipe.
* * fhandler_console.cc (fhandler_console::read): Don't even think about breakingChristopher Faylor2000-03-121-1/+0
