remove ifdef USE_KKCC.
src/ChangeLog:
2003-01-08 Mike Sperber <mike@xemacs.org>
* console.h (CDFW_CONSOLE): Don't lead to a crash if we're dealing
with a dead window/frame/device/console.
2002-12-20 Mike Sperber <mike@xemacs.org>
* ui-gtk.c: Fix typo from Ben's patch: emacs_ffi_data is a
typedef, not a struct. emacs_gtk_object_data is a typedef, not a
struct.
* gtk-glue.c (gdk_event_to_emacs_event): Fix typos from Ben's
patch: le -> emacs_event + rearrange the code.
* event-gtk.c (gtk_event_to_emacs_event): Fix typos from Ben's
patch: ..._UNDERLYING_GDK_EVENT -> ..._GDK_EVENT, ev -> key_event.
* device-gtk.c: Fix typo from Ben's patch: x_keysym_map_hash_table
-> x_keysym_map_hashtable.
2002-12-19 Mike Sperber <mike@xemacs.org>
* menubar-x.c (set_frame_menubar): Initialize protect_me field of
popup_data.
2002-12-16 Ben Wing <ben@xemacs.org>
Major cleanup of KKCC, etc.
KKCC, pdump-related:
-- descriptions are written for all objects. this required some
changes in the format of some objects, e.g. extents, popup-data,
coding system, lstream, lcrecord-list.
-- KKCC now handles weakness in markers, hash tables, elsewhere
correctly (formerly, you'd eventually get a stack overflow due
to endlessly expanding markers).
-- textual changes: lrecord_description -> memory_description,
struct_description -> sized_memory_description.
-- extensive comment describing descriptions and pdump.
-- redo XD_UNION so it works inline and change its format to provide
sufficient info for pdump. implement XD_UNION in pdump. also add
XD_UNION_DYNAMIC_SIZE, which works like XD_UNION except for when
auto-computing structure sizes.
-- add support for XD_INDIRECT in description offsets (used by
extents).
-- add support for "description maps", allowing for indirect
descriptions that are retrieved from an object at run-time. this
generalizes XD_CODING_SYSTEM_END, XD_SPECIFIER_END, etc., which
have now been eliminated.
-- add a fifth field "flags" to memory_description, to support flags
that can be specified for this particular line. Currently defined
flags are XD_FLAG_NO_KKCC (KKCC should ignore this entry; useful
for the weakness above in markers, etc.), XD_FLAG_NO_PDUMP (pdump
should ignore this entry), XD_FLAG_UNION_DEFAULT_ENTRY (in
union maps, this specifies a "default" entry for all remaining
values), and XD_FLAG_FREE_LISP_OBJECT (for use with lcrecord-lists).
-- clean up the kkcc-itis in events, so that the differences
between event data as separate objects and as a union are now
minimized to a small number of places. with the new XD_UNION, we
no longer need event data as separate objects, so this code is no
longer ifdef USE_KKCC, but instead ifdef EVENT_DATA_AS_OBJECTS,
not used by default. make sure that we explicitly free the
separate event data objects when no longer in use, to maintain the
invariant the event processing causes no consing.
-- also remove other USE_KKCC ifdefs when not necessary.
-- allow for KKCC compilation under MS Windows.
-- fix README.kkcc.
-- dump_add_root_object -> dump_add_root_lisp_object.
-- implement dump_add_root_block and use this to handle
dump_add_opaque.
-- factor out some code duplicated in kkcc and pdump.
Other allocation/object-related:
-- change various *slots.h so MARKED_SLOT() call no longer
includes semicolon.
-- free_marker() takes a Lisp_Object not a direct pointer.
-- make bit vectors lcrecords, like vectors, and eliminate code
that essentially duplicated the lcrecord handling.
-- additional asserts in FREE_FIXED_TYPE, formerly duplicated in
the various callers of this.
-- all lcrecord allocation functions now zero out the returned
lcrecords. unnecessary calls to zero_lcrecord removed. add long
comment describing these functions.
-- extract out process and coding system slots, like for buffers,
frames, etc.
-- lcrecords now set the type of items sitting on the free list to
lcrecord_type_free.
-- changes to the way that gap arrays are allocated, for kkcc's
benefit -- now, one single memory block with a stretchy array on
the end, instead of a separate block holding the array.
Error-checking-related:
-- now can compile with C++ under MS Windows. clean up compile errors
discovered that way. (a few were real problems)
-- add C++ error-checking code to verify problems with mismatched
GCPRO/UNGCPRO. (there were a few in the kkcc code.) add long
comment about how to catch insufficient GCPRO (yes, it's possible
using C++).
-- add debug_p4(), a simple object printer, when debug_print()
doesn't work.
-- add dp() and db() as short synonyms of debug_print(),
debug_backtrace().
-- `print' tries EXTREMELY hard to avoid core dumping when printing
when crashing or from debug_print(), and tries as hard as it
reasonably can in other situations.
-- Correct the message output upon crashing to be more up-to-date.
Event-related:
-- document event-matches-key-specifier-p better.
-- generalize the dispatch queues formerly duplicated in the
various event implementations. add event methods to drain pending
events. generalize and clean up QUIT handling, removing
event-specific quit processing. allow arbitrary keystrokes, not
just ASCII, to be the QUIT char. among other things, this should
fix some longstanding bugs in X quit handling. long comment
describing the various event queues.
-- implement delaying of XFlush() if there are pending expose events.
SOMEONE PLEASE TRY THIS OUT.
-- Fix `xemacs -batch -l dunnet' under Cygwin. Try to fix under
MS Windows but not quite there yet.
Other:
-- class -> class_ and no more C++ games with this item.
new -> new_ in the lwlib code, so far not elsewhere.
-- use `struct htentry' not `struct hentry' in elhash.c to avoid
debugger confusion with hash.c.
-- new macros ALIST_LOOP_3, ALIST_LOOP_4.

28 ;;; Synched up with: Not in FSF. | |
29 | |
30 ;;; Commentary: | |
31 | |
32 ;; Gnuserv is run when Emacs needs to operate as a server for other | |
33 ;; processes. Specifically, any number of files can be attached for | |
34 ;; editing to a running XEmacs process using the `gnuclient' program. | |
35 | |
36 ;; Use `M-x gnuserv-start' to start the server and `gnuclient files' | |
37 ;; to load them to XEmacs. When you are done with a buffer, press | |
38 ;; `C-x #' (`M-x gnuserv-edit'). You can put (gnuserv-start) to your | |
39 ;; .emacs, and enable `gnuclient' as your Unix "editor". When all the | |
40 ;; buffers for a client have been edited and exited with | |
41 ;; `gnuserv-edit', the client "editor" will return to the program that | |
42 ;; invoked it. | |
43 | |
44 ;; Your editing commands and Emacs' display output go to and from the | |
45 ;; terminal or X display in the usual way. If you are running under | |
46 ;; X, a new X frame will be open for each gnuclient. If you are on a | |
47 ;; TTY, this TTY will be attached as a new device to the running | |
48 ;; XEmacs, and will be removed once you are done with the buffer. | |
49 | |
50 ;; To evaluate a Lisp form in a running Emacs, use the `-eval' | |
51 ;; argument of gnuclient. To simplify this, we provide the `gnudoit' | |
52 ;; shell script. For example `gnudoit "(+ 2 3)"' will print `5', | |
53 ;; whereas `gnudoit "(gnus)"' will fire up your favorite newsreader. | |
54 ;; Like gnuclient, `gnudoit' requires the server to be started prior | |
55 ;; to using it. | |
56 | |
57 ;; For more information you can refer to man pages of gnuclient, | |
58 ;; gnudoit and gnuserv, distributed with XEmacs. | |
59 | |
60 ;; gnuserv.el was originally written by Andy Norman as an improvement | |
61 ;; over William Sommerfeld's server.el. Since then, a number of | |
62 ;; people have worked on it, including Bob Weiner, Darell Kindred, | |
63 ;; Arup Mukherjee, Ben Wing and Jan Vroonhof. It was completely | |
64 ;; rewritten (labeled as version 3) by Hrvoje Niksic in May 1997. The | |
65 ;; new code will not run on GNU Emacs. | |
66 | |
67 ;; Jan Vroonhof <vroonhof@math.ethz.ch> July/1996 | |
68 ;; ported the server-temp-file-regexp feature from server.el | |
69 ;; ported server hooks from server.el | |
70 ;; ported kill-*-query functions from server.el (and made it optional) | |
71 ;; synced other behavior with server.el | |
72 ;; | |
73 ;; Jan Vroonhof | |
74 ;; Customized. | |
75 ;; | |
76 ;; Hrvoje Niksic <hniksic@xemacs.org> May/1997 | |
77 ;; Completely rewritten. Now uses `defstruct' and other CL stuff | |
78 ;; to define clients cleanly. Many thanks to Dave Gillespie! | |
79 ;; | |
80 ;; Mike Scheidler <c23mts@eng.delcoelect.com> July, 1997 | |
81 ;; Added 'Done' button to the menubar. | |
