mc-alloc bug?
17 years, 2 months
Jerry James
I've built a 21.5 from CVS of just before the cvs.xemacs.org crash, on
a 32-bit Pentium 4. I ran it under valgrind and got some errors
before the frame is mapped. Here's the first one:
==11577== Invalid write of size 1
==11577== at 0x4006614: memset (mc_replace_strmem.c:490)
==11577== by 0x832B7BD: mc_alloc_1 (string3.h:96)

==11577== by 0x816D20C: xmalloc_and_zero (alloc.c:402)
==11577== by 0x832B536: mc_alloc_1 (mc-alloc.c:1150)
==11577== by 0x816BBC4: alloc_lrecord (alloc.c:582)
==11577== by 0x816C7EF: Fcons (alloc.c:1273)
==11577== by 0x8322059: read_list_conser (lread.c:2977)

==11577== by 0x8324180: Fload_internal (lread.c:768)
This is followed by a complaint about accessing 1 byte after the same
block, so that memset manages to go 2 bytes after the end of the
allocated block. I don't understand the mc-alloc.c code well enough
to judge yet, but here's a guess at what might be happening.
The error happens during startup, so we are allocating like mad but
not freeing anything. Therefore, there is only one page on the free
list, and it is mostly allocated already; in fact, it has fewer than
sizeof(struct Lisp_Opaque) bytes left, which is more than
USED_LIST_MIN_OBJECT_SIZE but less than USED_LIST_UPPER_THRESHOLD.
The call to make_opaque_ptr -> alloc_lrecord -> mc_alloc_1 thus has
only the one page to consider. The call to get_used_list_index at the
top of mc_alloc_1 returns 4, if I have counted correctly, so
plh = USED_HEAP_PAGES (get_used_list_index (size));
set plh to &mc_allocator_globals.used_heap_pages[4]. Since the size
is small enough, a call to allocate_cell is then made. Here's the
part I'm not so sure about. None of the remaining code checks that a
sufficient number of bytes remain on that page. Or do we always
allocate an entire page? In any case, the memset a few lines down is
running off the end of the allocated block by 2 bytes, so something
like this scenario must be happening. I'll try to track it down in
more detail when I have a little more free time.

[Bug: 21.4.20] Problem when open vhdl file
17 years, 2 months
Jim Huang
================================================================
Dear Bug Team!
I had problem when I open the VHDL file (.vhd). In windows, I set the xemacs
is the default
Editor to open .vhd file. Everytime when I open a .vhd file by
double-clicking the file's icon or open the
file with the windows command line, e.g "xemace aaa.vhd", the file can not
be correctly displayed.
No text, and the top of file looks like blinking.
The solution is simple, every time I just resize the xemacs window a little
bit, or minimum the
Xemacs window and restore it again, then the display goes well.
If I open the .vhd file from the xemacs window, no problem at all.
-Best Regards
Jim Huang

Bug tracker: next steps
17 years, 2 months
Hans de Graaff
So looking through all the feedback it seems to be that only roundup and
bugzilla may qualify for the set of requirements that have been thrown
around, and from those roundup seems to be the most favored one.
So I think the next step is to get a test installation going and see if
roundup can be configured in a way that will satisfy most of the
requirements. I'll see if I can get something going as a temporary
installation that we can play with.
In the meantime it probably makes sense to start looking for a place to
host the tracker. Adrian, can you pick this up?
Kind regards,
Hans

Which packages are externally maintained ?
17 years, 2 months
Didier Verna
Hi there,
I have a bunch of Custom-related fixes for several packages, but I'm not
sure which ones are externally maintained and/or if it's OK to commit
directly into our own package tree.
Norbert, what's the preferred way to go ? Here are the packages involved
in my changes:
xemacs-packages/dired
xemacs-packages/erc
xemacs-packages/eshell
xemacs-packages/hm--html-menus
xemacs-packages/liece
xemacs-packages/riece
xemacs-packages/vm
xemacs-packages/w3
xemacs-packages/xwem
Thanks !

[BUG ?] Annoying owner / permission on some lisp files
17 years, 2 months
Didier Verna
Hi !
I've just noticed this in both 21.4 and 21.5: I usually compile as user
'didier' on my machine, and run XEmacs in place. Recently, I also
installed XEmacs in /usr/local, hence I did a make install as root.
Now, after "make install" completes, I notice that all the
auto-autoloads files, along with finder-inf in the *source* tree have
their owner changed to 'root'. This is very annoying because it prevents
me from recompiling the source once more.
