[xemacs-hg @ 2003-03-02 09:38:37 by ben]
To: xemacs-patches@xemacs.org
PROBLEMS: Include nt/PROBLEMS and update. Add note about incremental
linking badness.
cmdloop.el, custom.el, dumped-lisp.el, files.el, keydefs.el, keymap.el, lisp-mode.el, make-docfile.el, replace.el, simple.el, subr.el, view-less.el, wid-edit.el: Lots of syncing with FSF 21.2.
Use if-fboundp in wid-edit.el.
New file newcomment.el from FSF.
internals/internals.texi: Fix typo.
(Build-Time Dependencies): New node.
PROBLEMS: Delete.
config.inc.samp, xemacs.mak: Eliminate HAVE_VC6, use SUPPORT_EDIT_AND_CONTINUE in its place.
No incremental linking unless SUPPORT_EDIT_AND_CONTINUE, since it
can cause nasty crashes in pdump. Put warnings about this in
config.inc.samp. Report the full compile flags used for src
and lib-src in the Installation output.
alloc.c, lisp.h, ralloc.c, regex.c: Use ALLOCA() in regex.c to avoid excessive stack allocation.
Also fix subtle problem with REL_ALLOC() -- any call to malloc()
(direct or indirect) may relocate rel-alloced data, causing
buffer text to shift. After any such call, regex must update
all its pointers to such data. Add a system, when
ERROR_CHECK_MALLOC, whereby regex.c indicates all the places
it is prepared to handle malloc()/realloc()/free(), and any
calls anywhere in XEmacs outside of this will trigger an abort.
alloc.c, dialog-msw.c, eval.c, event-stream.c, general-slots.h, insdel.c, lisp.h, menubar-msw.c, menubar-x.c: Change *run_hook*_trapping_problems to take a warning class, not
a string. Factor out code to issue warnings, add flag to
call_trapping_problems() to postpone warning issue, and make
*run_hook*_trapping_problems issue their own warnings tailored
to the hook, postponed in the case of safe_run_hook_trapping_problems()
so that the appropriate message can be issued about resetting to
nil only when not `quit'. Make record_unwind_protect_restoring_int()
non-static.
dumper.c: Issue notes about incremental linking problems under Windows.
fileio.c: Mule-ize encrypt/decrypt-string code.
text.h: Spacing changes.

5 New KKCC-GC mark algorithm: | |
6 configure flag : --use-kkcc | |
7 | |
8 For better understanding, first a few words about the mark algorithm | |
9 up to now: | |
10 Every Lisp_Object has its own mark method, which calls mark_object | |
11 with the stuff to be marked. | |
12 Also, many Lisp_Objects have pdump descriptions, which are used by | |
13 the portable dumper. The dumper gets all the information it needs | |
14 about the Lisp_Object from the descriptions. | |
15 | |
16 Also the garbage collector can use the information in the pdump | |
17 descriptions, so we can get rid of the mark methods. | |
18 That is what we have been doing. | |
19 | |
20 | |
21 DUMPABLE FLAG | |
22 ------------- | |
23 First we added a dumpable flag to lrecord_implementation. It shows, | |
24 if the object is dumpable and should be processed by the dumper. | |
25 The dumpable flag is the third argument of a lrecord_implementation | |
26 definition (DEFINE_LRECORD_IMPLEMENTATION). | |
27 If it is set to 1, the dumper processes the descriptions and dumps | |
28 the Object, if it is set to 0, the dumper does not care about it. | |
29 | |
30 | |
31 TODO | |
32 ---- | |
1204 | 33 After all Lisp_Objects have pdump descriptions (THEY DO NOW!!), |
992 | 34 (mark_with_description) can get rid of the mark_object calls. |
35 | |
36 | |
1204 | 37 There are a few Lisp_Objects, where there occured differences and |
38 inexactness between the mark-method and the pdump description. All | |
39 these Lisp_Objects get dumped (except image instances), so their | |
40 descriptions have been written, before we started our work: | |
41 | |
42 * alloc.c: lcrecord_list | |
43 description: | |
44 mark: performs extra gc_checking_assert() for various checks. | |
992 | 45 |
46 * alloc.c: cons | |
47 description: car and cdr | |
48 mark: cdr is marked, only if its != Qnil | |
49 | |
50 * alloc.c: string | |
1204 | 51 description: ??? |
52 mark: ??? | |
992 | 53 |
1204 | 54 * buffer.c: buffer |
55 description: XD_LISP_OBJECT indirect_children | |
56 mark: indirect_children not marked if Qnull_pointer | |
992 | 57 |
58 * eval.c: subr | |
59 description: XD_DOC_STRING doc | |
60 mark: empty, nothing is marked | |
61 | |
62 * file-coding.c: coding_system | |
1204 | 63 description: ??? |
64 mark: ??? | |
992 | 65 |
1204 | 66 * glyphs.c: image_instance |
67 description: | |
68 mark: mark method sets device to nil if dead |
