idle carbon2 xemacs taking up cpu
15 years, 11 months
Kaarthik Sivakumar
Kaarthik Sivakumar
Hi
I am running xemacs from the carbon2 branch on my mac. I find that after a
few hours of inactivity, xemacs takes up a lot of cpu constantly, using
about 60-80% of the cpu (and firefox the remaining). I had one such xemacs
instance under gdb, but I know neither xemacs internals nor carbon. So any
help getting to the root of this problem will be useful. I can help debug
the problem when it happens next, if I am given clues about where to look
for what.
I ran dapptrace (dtrace script for tracing function calls) and I have put
the output here:
http://mirthmakers.com/code/xemacs-dapptrace.txt
This file is really large, as I turned on all the options for dapptrace,
just to get as much data as possible (may be too much though, now that I
look at the output).
Here is the gdb backtrace, in case this is useful for someone. It just does
this all the time.

problems with frames on multiple X displays
15 years, 11 months
Greg Klanderman
Greg Klanderman
So I pretty regularly have frames open on multiple X displays (my
xemacs at work has frames open there as well as on my home computer),
and the biggest problem is that the DISPLAY environment variable
passed to sub-processes is always the one xemacs inherited from the
shell when it was started, rather than the one associated with the
currently selected device.
It looks like this could be fixed deep down in child_setup in
callproc.c, somewhere in the middle (in Fstart_process_internal in
process.c or maybe unix_create_process in process-unix.c) or even in
lisp by binding process-environment appropriately around the calls to
start-process-internal in start-process and call-process-internal.
Can someone give me guidance on how best to approach this?
thanks,
Greg

Right, or (device-connection (selected-device))
> This is my utility function
Using the select-frame-hook seems a bit hacky; As I said, it can be
done by binding process-environment appropriately in two places in
lisp; more specifically:
(defun process-environment-for-selected-device ()
(let ((d (selected-device)))
(if (eq (device-type d) 'x)
(cons (format "DISPLAY=%s" (device-connection d))
process-environment)
(remove-if (lambda (v)
(string-match "^DISPLAY=" v))
process-environment))))
(defadvice start-process-internal (around set-display-for-device activate)
(let ((process-environment (process-environment-for-selected-device)))
ad-do-it))
(defadvice old-call-process-internal (around set-display-for-device activate)
(let ((process-environment (process-environment-for-selected-device)))
ad-do-it))
But it really seems like this is the correct behavior and that xemacs
should always just work this way. That's what I was hoping for
guidance on - whether there is agreement that this it the right thing,
and if so where to make the change.
thanks,
Greg

[Bug: 21.5-b28] Carbon crash when I click on the Info icon

Dear Bug Team!
When I start Carbon XEmacs, click on the Info icon (shaped like a
lifebelt), I get the below crash. I don't know why.
Bye,

minibuffer-confirm-incomplete hoses find-file in nonexistent directory
15 years, 11 months
Greg Klanderman
Greg Klanderman
Another bug which I'd like to get fixed is the following:
If minibuffer-confirm-incomplete is nil, then attempting to find a
file (C-x C-f) in a directory that does not exist prompts:
| The directory containing <file> does not exist. Create? (yes or no)
and if you type "yes" it works as expected.
However, if minibuffer-confirm-incomplete is T, then you get the
following error:
| Opening directory: No such file or directory, <file>
and are returned to the find-file minibuffer prompt.
I fixed this locally some time ago by wrapping (ignore-errors ...)
around the call to try-completion in the function exit-minibuffer in
minibuf.el, and it seems to solve the problem.
Does that sound like an appropriate fix? If so I can submit a patch..
thanks,
Greg

this looks like a bug in GET-BUFFER-WINDOW..
15 years, 11 months
Greg Klanderman
Greg Klanderman
[please CC me on replies; I am no longer on xemacs-beta]
Hi,
In trying to come up with a recipe to reliably exhibit the crash I
reported as issue #331:
http://tracker.xemacs.org/XEmacs/its/issue331
I've come across what I believe is a bug in the window_loop function
used by GET-BUFFER-WINDOW and several other elisp primitives defined
in src/window.c.
The documentation for GET-BUFFER-WINDOW says the following about the
optional WHICH-DEVICES argument:
| If nil or omitted, search all devices on the selected console.
| [...]
| If a console, search all devices on that console.
I interpret that to mean either of these forms:
(get-buffer-window "foo" 'visible)
(get-buffer-window "foo" 'visible NIL)
should be equivalent to:
(get-buffer-window "foo" 'visible (selected-console))
However, this is not the case: the first two forms will return windows
on consoles other than the selected console.
Looking at the code, the problem seems pretty clear. Just inside the
device loop is the following code:
| if (frame)
| XSETFRAME (the_frame, frame);
| else
| the_frame = DEVICE_SELECTED_FRAME (XDEVICE (device));
|
| if (NILP (the_frame))
| continue;
|
| if (!device_matches_device_spec (device,
| NILP (which_devices) ?
| FRAME_CONSOLE (XFRAME (the_frame)) :
| which_devices))
| continue;
So when FRAME is not set, and WHICH_DEVICES is NIL, we check the
device currently being considered against that same device's selected
frame's console, which will tautologically match.
Since FRAME is not set when WHICH_FRAMES is 'VISIBLE, 0, or T, that is
exactly when the bug is manifested.
Fixing this seems a simple matter of adding the line:
| if (NILP (which_devices))
| which_devices = selected_frame ();
toward the top of the function, and changing the device check to:
| if (!device_matches_device_spec (device, which_devices))
| continue;
I can test this change and submit a proper patch if someone will
confirm that this analysis sounds right.
The code in question was last touched in April 2001 by Michael
Sperber, however that appears to have just been some sort of merge,
the commit message is:
| The Great Trunk Move from release-21-4.
The code was previously changed by Martin Buchholz in November 2000
with the commit message
| next-frame crashes fixed
and that appears to be the change that introduced this bug.
Incidentally, the other use of THE_FRAME just below the code cited:
| /* Pick a window to start with. */
| if (WINDOWP (obj))
| w = obj;
| else
| w = FRAME_SELECTED_WINDOW (XFRAME (the_frame));
does seem to be correct.
Back to issue #331, while I have reproduced the original crash once, I
unfortunately cannot yet do so reliably. I do suspect that fixing the
bug described here would avoid the crash in the majority of cases,
though I believe it would still be possible when WHICH-DEVICES is T.
thanks for your time,
Greg

For that, a separate repository works better, I think.

That's exactly where I find MQ extremely useful: As I find something
unrelated, I pop the patches I'm working on, work on the unrelated
thing, then push it back.

Reanimating verilog-mode
15 years, 11 months
Marcus Harnisch
Marcus Harnisch
Hi all
Verilog-mode in our prog-modes package dates back to 2005. Since I
tend to use the upstream version, I never noticed.
I'd love to integrate the latest version (and monitor future upstream
changes -- in case you would ask, Stephen).
It looks like there are only few package specific changes in the code
but unfortunately, I don't have access to the original sources from
which the package has been created to see what exactly has been
changed.
Regards
Marcus
