[xemacs-hg @ 2002-11-27 07:15:02 by ben] bug fixes, profiling debugging improvements configure.in: Check for GCC version and only use -Wpacked in v3. .cvsignore: Add .idb, .ilk for MS Windows VC++. cl-macs.el: Document better. cmdloop.el: Removed. Remove nonworking breakpoint-on-error now that debug-on-error works as documented. help.el: Extract out with-displaying-help-buffer into a more general mechanism. lib-complete.el: Support thunks in find-library-source-path. startup.el: Don't catch errors when noninteractive, because that makes stack traces from stack-trace-on-error useless. .cvsignore: Windows shit. alloc.c: Better redisplay-related assert. elhash.c: Comment change. eval.c: Don't generate large warning strings (e.g. backtraces) when they will be discarded. Implement debug-on-error as documented -- it will enter the debugger and crash when an uncaught signal happens noninteractively and we are --debug. Better redisplay-related asserts. frame-msw.c, frame.c, lisp.h, redisplay.c, scrollbar-gtk.c, scrollbar-x.c, signal.c, sysdep.c: Fix up documentation related to QUIT (which CANNOT garbage-collect under any circumstances), and to redisplay critical sections. lread.c: Add load-ignore-out-of-date-elc-files, load-always-display-messages, load-show-full-path-in-messages for more robust package compilation and debugging. profile.c: Overhaul profile code. Change format to include call count and be extensible for further info. Remove call-count-profile-table. Add set-profiling-info. See related profile.el changes (which SHOULD ABSOLUTELY be in the core! Get rid of xemacs-devel and xemacs-base packages *yesterday*!).

-This happens by calling `force-debugging-signal'.  This can be very
-useful when debugging noninteractive errors in tricky situations,
-e.g. makefiles, since you can set this variable using an environment
-variable, like this:
-
-\(using csh)      setenv XEMACSDEBUG '(setq breakpoint-on-error t)'
-\(using bash)     export XEMACSDEBUG='(setq breakpoint-on-error t)'

-display a Lisp backtrace when exiting noninteractively due to an unhandled
-error.")
