CVS diff on the sources is your friend. (^^;;; Sorry, it's not just the patches you have to disentangle when you're working with Ben's contributions.... My bad. src/ChangeLog addition: 2001-06-08 Ben Wing <ben(a)xemacs.org&gt; ------ gc-in-window-procedure fixes ------ * alloc.c: * alloc.c (struct post_gc_action): * alloc.c (register_post_gc_action): * alloc.c (run_post_gc_actions): * alloc.c (garbage_collect_1): Create "post-gc actions", to avoid those dreaded "GC during window procedure" problems. * event-msw.c: Abort, clean and simple, when GC in window procedure. We want to flush these puppies out. * glyphs-msw.c: * glyphs-msw.c (finalize_destroy_window): * glyphs-msw.c (mswindows_finalize_image_instance): Use a post-gc action when destroying subwindows. * lisp.h: Declare register_post_gc_action(). * scrollbar-msw.c: * scrollbar-msw.c (unshow_that_mofo): Use a post-gc action when unshowing scrollbar windows, if in gc. * redisplay.c (mark_redisplay): Add comment about the utter evilness of what's going down here. ------ cygwin setitimer fixes ------ * Makefile.in.in (sheap_objs): * Makefile.in.in (profile_objs): * Makefile.in.in (objs): Compile profile.c only when HAVE_SETITIMER. * nt.c (mswindows_sigset): * nt.c (mswindows_sighold): * nt.c (mswindows_sigrelse): * nt.c (mswindows_sigpause): * nt.c (mswindows_raise): * nt.c (close_file_data): Style fixes. * nt.c: Move setitimer() emulation to win32.c, because Cygwin needs it too. * profile.c: * profile.c (Fstart_profiling): * profile.c (Fstop_profiling): Make sure we don't compile if no setitimer(). Use qxe_setitimer() instead of just plain setitimer(). * signal.c: * signal.c (set_one_shot_timer): * signal.c (alarm): Define qxe_setitimer() as an encapsulation around setitimer() -- call setitimer() directly unless Cygwin or MS Win, in which case we use our simulated version in win32.c. * systime.h: * systime.h (struct itimerval): * systime.h (ITIMER_REAL): Prototype mswindows_setitimer() and qxe_setitimer(). Long comment about "qxe" and the policy regarding encapsulation. * win32.c: * win32.c (setitimer_helper_proc): * win32.c (setitimer_helper_period): * win32.c (setitimer_helper): * win32.c (mswindows_setitimer): Move setitimer() emulation here, so Cygwin can use it. Rename a couple of functions and variables to be longer and more descriptive. In setitimer_helper_proc(), send the signal using either mswindows_raise() or (on Cygwin) kill(). If for some reason we are still getting lockups, we'll change the kill() to directly invoke the signal handlers. ------ windows shell fixes ------ * callproc.c: * ntproc.c: Comments about how these two files must die. * callproc.c (init_callproc): On MS Windows, init shell-file-name from SHELL, then COMSPEC, not just COMSPEC. (more correct and closer to FSF.) Don't force a value for SHELL into the environment. (Comments added to explain why not.) * nt.c (init_user_info): Don't shove a fabricated SHELL into the environment. See above. lisp/ChangeLog addition: 2001-06-08 Ben Wing <ben(a)xemacs.org&gt; * process.el: comment about shell-command-switch. * process.el (shell-quote-argument): Need to quote a null argument, too. From Dan Holmsand. * startup.el (normal-top-level): Delete some unused FSF junk. * startup.el (command-line-early): * startup.el (command-line): Call MS Windows init function. * win32-native.el: * win32-native.el (mswindows-system-shells): New. * win32-native.el (mswindows-system-shell-p): New. * win32-native.el (init-mswindows-at-startup): New. * win32-native.el (mswindows-quote-one-vc-runtime-arg): * win32-native.el (mswindows-quote-one-simple-arg): * win32-native.el (mswindows-quote-one-command-arg): * win32-native.el (mswindows-construct-process-command-line-alist): Correct comments at top. Correctly handle passing arguments to Cygwin programs and to bash. Fix quoting of zero-length arguments (from Dan Holmsand). Set shell-command-switch based on shell-file-name, which in turn comes from env var SHELL. -- University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Institute of Policy and Planning Sciences Tel/fax: +81 (298) 53-5091 _________________ _________________ _________________ _________________ What are those straight lines for?
