From 8dca9e230217cc6f4ded94e5fa0ab3f63df941b9 Mon Sep 17 00:00:00 2001 From: Christopher Faylor Date: Sun, 18 Aug 2002 05:49:26 +0000 Subject: * perthread.h (vfork_save): Add ctty, sid, pgid, exitval fields. (vfork_save::restore_pid): New method. (vfork_save::restore_exit): New method. * fork.cc (vfork): Save ctty, sid, pgid and restore them when returning to "parent". Use exitval field if exiting but never created a new process. * syscalls.cc (setsid): Detect when in "vfork" and force an actual fork so that pid will be allocated (UGLY!). (getsid): New function. * dcrt0.cc (do_exit): Use vfork_save::restore_exit method for returning from a vfork. * spawn.cc (spawnve): Use vfork_save::{restore_pid,restore_exit} methods for returning from vfork. * cygwin.din: Export getsid. * include/cygwin/version.h: Bump api minor number. * malloc.cc: #ifdef sYSTRIm for when MORECORE_CANNOT_TRIM is true. --- winsup/cygwin/spawn.cc | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) (limited to 'winsup/cygwin/spawn.cc') diff --git a/winsup/cygwin/spawn.cc b/winsup/cygwin/spawn.cc index 602c0af69..8c1c18adb 100644 --- a/winsup/cygwin/spawn.cc +++ b/winsup/cygwin/spawn.cc @@ -907,11 +907,13 @@ spawnve (int mode, const char *path, const char *const *argv, case _P_DETACH: subproc_init (); ret = spawn_guts (path, argv, envp, mode); - if (vf && ret > 0) + if (vf) { debug_printf ("longjmping due to vfork"); - vf->pid = ret; - longjmp (vf->j, 1); + if (ret < 0) + vf->restore_exit (ret); + else + vf->restore_pid (ret); } break; default: -- cgit v1.2.3
