[PATCH] Make GC dependent on % of total memory consed
20 years, 1 month
Ben Wing
Ben Wing
This one I'm not committing quite yet, as it is a (somewhat) user-visible
change. I'm interested in comments. With this change, GC will not happen
until at least 40% (a random guess) of current Lisp-object memory has been
allocated. The purpose of this is to make GC time be a constant amortized
percentage of total run time, regardless of how big XEmacs is. (Currently,
GC time will become a progressively larger percent of total time as the
size of XEmacs increases.) Note that the lower bound in gc-cons-threshold
(500K) still applies.

src/ChangeLog addition:
2005-09-27 Ben Wing <ben(a)xemacs.org>
* alloc.c (garbage_collect_1):
Avoid use of reserved C++ `catch'.
* alloc.c:
* alloc.c (gc_plist_hack):
* alloc.c (HACK_O_MATIC):
* alloc.c (Fgarbage_collect):
* alloc.c (Ftotal_memory_usage):
* alloc.c (Flisp_object_memory_usage):
* alloc.c (recompute_need_to_garbage_collect):
* alloc.c (common_init_alloc_early):
* alloc.c (syms_of_alloc):
* alloc.c (vars_of_alloc):
Rename underused `memory-usage' to `total-memory-usage'.
Add `lisp-object-memory-usage'. Reimplement `gc-cons-percentage'
to be a percentage of total Lisp object allocation (not total
memory of all sorts, which is hard to calculate in any case) and
give it a preliminary value of 40%. Use EMACS_INT instead of
int in a couple of places.

[AC21.4R21.5] Email truncation bug begone!

APPROVE COMMIT 21.5 RECOMMEND 21.4
David,
I took much too long to process this. I can only claim extreme busyness
with some Real Life stuff over the last several weeks. Thank you so
much for analyzing the problem and coming up with a fix. I'm going to
give credit where credit is due (although I did tweak your patch very
slightly in a couple of ways). The 21.5 patch, which I am committing,
is first, followed by the 21.4 version of the patch. Both have the same
ChangeLog entry.

[C] xemacs-21.5-clean: Getting texinfmt.el to compile core .texi again
20 years, 1 month
Adrian Aichner
Adrian Aichner
COMMIT
Ben, Stephen, please review this.
These are my final changes to get all of XEmacs/xemacs/man/ .texi
files compile again with my updated texinfmt.el (Thanks, viteno, for
already generating a texinfo pre-release!).
Best regards,
Adrian

Xft branch - code cut error in font.el
20 years, 1 month
Clemens Fruhwirth
Clemens Fruhwirth
There is a small error in font.el of the Xft branch leading to a
malfunctioning font-default-font-for-device.
Have a look at
http://cvs.xemacs.org/viewcvs.cgi/XEmacs/xemacs/lisp/font.el.diff?r1=1.16...
Obviously the else path has not been removed when the if statement for
font-running-xemacs was removed.
The "patch" below removes the remains.
Stephen: The patch from Daniel Pittman
http://list-archive.xemacs.org/xemacs-patches/200507/msg00058.html
gives a nice speed gain. He hasn't merged the patch himself yet. Would
you like to do that, while you're at the code? :)
Thanks for your work!
