When I did a fresh update, the option showed up properly in the summary.[1] The other two problems I described (continual refresh when updating tabs in a partially obscured frame) and the missing separator line when `C-x o'ing to a window without a tab are still there.

bad change to buffer-string 25 years, 3 months

William M. Perry

You used to be able to do (buffer-string nil nil somebuffer) to get the entire string out of a buffer. With XEmacs 21.2, it has been changed to just take a 'buffer' arguent, but it is _supposed_ to be backwards compatible and take 'buffer old-end old-buffer' arguments. But if you pass in nil for 'buffer', it thinks you want the new way and 'nil' means current-buffer. This broke the content-id (cid) url handling in Emacs/W3 + pGnus. The offending code is: ;; This function used to be an alias to `buffer-substring', except ;; that FSF Emacs 20.4 added a BUFFER argument in an incompatible way. ;; The new FSF's semantics makes more sense, but we try to support ;; both for backward compatibility. (defun buffer-string (&optional buffer old-end old-buffer) "Return the contents of the current buffer as a string. If narrowing is in effect, this function returns only the visible part of the buffer. If BUFFER is specified, the contents of that buffer are returned. The arguments OLD-END and OLD-BUFFER are supported for backward compatibility with pre-21.2 XEmacsen times when arguments to this function were (buffer-string &optional START END BUFFER)." (if (or (null buffer) (bufferp buffer) (stringp buffer)) ;; The new way (buffer-substring nil nil buffer) ;; The old way (buffer-substring buffer old-end old-buffer))) I think this would be better written as: (cond ((or (stringp buffer) (bufferp buffer)) ;; most definitely the new way (buffer-substring nil nil buffer)) ((or (stringp old-buffer) (bufferp old-buffer) (natnump buffer) (natnump old-end)) ;; definitely the old way (buffer-substring buffer old-end old-buffer)) (t ;; probably the old way (buffer-substring buffer old-end old-buffer))) Might be a little more robust and preserve the old behaviour in the 'nil nil buff' case. -bp

Re: 21.2.19 SEGV on null frame pointer 25 years, 3 months

Karl Kleinpaste

[ sending this note back to the list, per private requests ] Kyle (and others), it didn't take long... XEmacs was started thus: xemacs -geometry 207x89+1282+0 -f gnus-init where "gnus-init" is just a small wrapper around Gnus' start-up for me: (defun gnus-init () "Start Gnus and smallify." (interactive) (gnus-no-server) (x-active-icon-toggle nil)) The exact keyboard sequence that had occurred when the SEGV was taken was that I was reading comp.emacs.xemacs (hm! :-), and I exited with a common set of keystrokes for me: q l < s g In Gnus, that means - quit the group - reduce the listed group set to only those with unread articles - goto the top of the *Group* buffer - save .newsrc* - get new news This is a very common key sequence for me; I do it a lot when I notice mail arriving via xbiff and want to go get it. I type that sequence a lot, and quickly. Significantly, there was - no mouse activity - no window manager activity Just keystrokes, maneuvering with bland Gnus command bindings. Gnus didn't even get as far as carrying out the `l' list-reduction command. It cleaned out the *Summary* buffer, leaving only *Group* showing, still cluttered with zero-message groups showing, and then stopped in gdb on SEGV. The stack trace is the same: SEGV thrown on 259 assert (EQ (FRAME_TYPE (f), sym)); I'm a little confused by the stack, considering that this is an inline func in frame.h; the next stack frame shows x_event_to_emacs_event() at a line where it's calling x_to_emacs_keysym()...there must be some macro call which gets to error_check_frame_type() somehow, but I don't see it right this instant. I'm leaving this (dying) XEmacs attached to the gdb which caught it, so I am open to suggestions for things to look at. Anything you'd like to see pobj'd...? --karl

RE: 21.2-b19: hang under Solaris 2.5.1 25 years, 3 months

RE: 21.2-b19: hang under Solaris 2.5.1 25 years, 3 months

Damon Lipparelli

The Solaris installation I'm using still has X11R5. Assuming you meant handle_focus_event_1 (in "event-Xt.c"), I just tried commenting out all calls to it. It's still hanging and the stack trace (appended) looks the same. -lipp ps: When I try invoking "src/xemacs -batch -vanilla -f batch-byte-compile" on one of the files that it is trying to build when it hangs, XEmacs returns after a second or so without a complaint, but no ".elc" file isn't produced. -----Original Message----- From: Andy Piper [mailto:andy＠xemacs.org] Sent: Wednesday, August 04, 1999 12:59 PM To: Damon Lipparelli; 'xemacs-beta(a)xemacs.org' Subject: RE: 21.2-b19: hang under Solaris 2.5.1 At 09:24 AM 8/4/99 -0700, Damon Lipparelli wrote: >I was wondering & thinking the same things.

Kyle Jones <kyle_jones(a)wonderworks.com> writes: > Can you remembner roughly what you are doing when the crash happens? > Clicking and dragging? Moving the mouse? Using the toolbar? It always occurs in the XEmacs in which I run Gnus; I've never seen it occur when not running Gnus. Generally speaking, my recollection is that it occurs when doing a series of command keystrokes in rapid succession. I know it has occurred once or twice in recent weeks when shifting via Ctrl-<arrow> keys into the fvwm2 pane where XEmacs lives (so the first event to handle is the need to redraw) and then hitting a couple keystrokes right away. For possibility exclusions: - I don't click-n-drag enough to know about, so that wouldn't be it. - I also don't use the toolbar appreciably. - All in all, I tend not to use the mouse a great deal, being a keyboard-centric sort of fellow. It'll happen again in a day or two at the most, I'm sure. I'll make sure to give some careful thought to exactly what Gnus was doing, and how I was ordering it about at the time. I'll drop you a note privately next time around. And thanx for the response. --karl

21.2.19 SEGV on null frame pointer 25 years, 3 months

Karl Kleinpaste

Does anyone care about this error at all? I don't do X internals much at all, never have, never really cared to. I've been reporting this occasionally since I first began using 21.2, around -b6 I believe, in the hope that someone might at least have an idea of what add'l info I could dredge up when it happens, to help identify the flaw. Still happens, once or twice a week -- something is misusing a null frame pointer as a consequence of Xt event handling. --karl Program received signal SIGSEGV, Segmentation fault. x_to_emacs_keysym (event=0x7ffff508, simple_p=0) at frame.h:259 259 assert (EQ (FRAME_TYPE (f), sym)); (gdb) bt #0 x_to_emacs_keysym (event=0x7ffff508, simple_p=0) at frame.h:259 #1 0x81b45d4 in x_event_to_emacs_event (x_event=0x7ffff508, emacs_event=0x8967280) at event-Xt.c:999 #2 0x81b67d3 in emacs_Xt_event_handler (wid=0x85b3528, closure=0x0, event=0x7ffff508, continue_to_dispatch=0x7ffff443 "\001ÀtP\b,") at event-Xt.c:2470 #3 0x2ab9cc9f in XtDispatchEventToWidget () #4 0x2ab9d6fd in _XtDefaultDispatcher () #5 0x2ab9d975 in XtDispatchEvent () #6 0x2aba83d5 in XtAppProcessEvent () #7 0x81b6f3f in emacs_Xt_event_pending_p (user_p=1) at event-Xt.c:2626 #8 0x80da8bd in detect_input_pending () at event-stream.c:945 #9 0x80dce11 in Fnext_event (event=146267928, prompt=137162676) at event-stream.c:2237 #10 0x807330e in Fcommand_loop_1 () at cmdloop.c:569 #11 0x807309d in command_loop_1 (dummy=137162676) at cmdloop.c:493 #12 0x8091785 in condition_case_1 (handlers=137162772, bfun=0x807304c <command_loop_1>, barg=137162676, hfun=0x80724d0 <cmd_error>, harg=137162676) at eval.c:1640 #13 0x8073538 in command_loop_2 (dummy=137162676) at cmdloop.c:255 #14 0x8091360 in internal_catch (tag=137236964, func=0x8073504 <command_loop_2>, arg=137162676, threw=0x0) at eval.c:1315 #15 0x8072937 in initial_command_loop (load_me=137162676) at cmdloop.c:304 #16 0x808cfa1 in xemacs_21_2_b19_i686_pc_linux (argc=5, argv=0x7ffff994, envp=0x7ffff9ac, restart=0) at emacs.c:1763 #17 0x808d72d in main (argc=5, argv=0x7ffff994, envp=0x7ffff9ac) at emacs.c:2188 (gdb) list 254 INLINE struct frame * 255 error_check_frame_type (struct frame * f, Lisp_Object sym); 256 INLINE struct frame * 257 error_check_frame_type (struct frame * f, Lisp_Object sym) 258 { 259 assert (EQ (FRAME_TYPE (f), sym)); 260 return f; 261 } 262 # define FRAME_TYPE_DATA(f, type) \ 263 ((struct type##_frame *) (error_check_frame_type (f, Q##type))->frame_data) (gdb) p f $1 = (struct frame *) 0x0 uname -a: Linux beaver.jprc.com 2.2.10-ac10 #1 SMP Tue Jul 13 13:23:27 EDT 1999 i686 unknown ./configure '--with-pop' '--with-mule' '--with-png' XEmacs 21.2-b19 "Shinjuku" configured for `i686-pc-linux'.
