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.

| 30 | |
| 31 ;; This file is dumped with XEmacs. | |
| 32 | |
| 33 ;; Combines autosaving for efs (to a local or remote directory) | |
| 34 ;; with the ability to do autosaves to a fixed directory on a local | |
| 35 ;; disk, in case NFS is slow. The auto-save file used for | |
| 36 ;; /usr/foo/bar/baz.txt | |
| 37 ;; will be | |
| 464 | 38 ;; AUTOSAVE/#=2Fusr=2Ffoo=2Fbar=2Fbaz.txt#" |
| 428 | 39 ;; assuming AUTOSAVE is the non-nil value of the variable |
| 40 ;; `auto-save-directory'. | |
| 41 | |
| 42 ;; Autosaves even if the current directory is not writable. | |
| 43 | |
| 44 ;; Can limit autosave names to 14 characters using a hash function, | |
| 45 ;; see `auto-save-hash-p'. | |
| 46 | |
| 47 ;; See `auto-save-directory' and `make-auto-save-file-name' and | |
| 48 ;; references therein for complete documentation. | |
| 49 | |
| 50 ;; `M-x recover-all-files' will effectively do recover-file on all | |
| 51 ;; files whose autosave file is newer (one of the benefits of having | |
| 52 ;; all autosave files in the same place). | |
| 53 | |
| 54 ;; This file is dumped with XEmacs. | |
| 55 | |
| 56 ;; If you want to autosave in the fixed directory /tmp/USER-autosave/ | |
| 57 ;; (setq auto-save-directory | |
| 58 ;; (concat "/tmp/" (user-login-name) "-autosave/")) | |
| 59 | |
| 60 ;; If you don't want to save in /tmp (e.g., because it is swap | |
| 464 | 61 ;; mounted) but rather in ~/.autosave/ |
| 428 | 62 ;; (setq auto-save-directory (expand-file-name "~/.autosave/")) |
| 63 | |
| 64 ;; If you want to save each file in its own directory (the default) | |
| 65 ;; (setq auto-save-directory nil) | |
| 66 ;; You still can take advantage of autosaving efs remote files | |
| 67 ;; in a fixed local directory, `auto-save-directory-fallback' will | |
| 68 ;; be used. | |
| 69 | |
| 70 ;; If you want to use 14 character hashed autosave filenames | |
| 71 ;; (setq auto-save-hash-p t) | |
| 72 | |
| 73 ;; Finally, put this line after the others in your ~/.emacs: | |
| 74 ;; (require 'auto-save) | |

| 120 If nil, each autosave files goes into the same directory as its | |

| 122 | |
| 123 A non-nil `auto-save-directory' could be on a local disk such as in | |
| 124 /tmp, then auto-saves will always be fast, even if NFS or the | |
| 125 automounter is slow. In the usual case of /tmp being locally mounted, | |

| 130 is mounted from swap (possible in SunOS, type `df /tmp' to find out) | |

| 228 Offers to autosave all files in the same `auto-save-directory'. All | |
| 229 autosave files can then be recovered at once with function | |
| 230 `recover-all-files'. | |
| 231 | |
| 232 Takes care to make autosave files for files accessed through efs | |
| 233 be local files if variable `efs-auto-save-remotely' is nil. | |
| 234 | |
| 235 Takes care of slashes in buffer names to prevent autosave errors. | |
| 236 | |
| 237 Takes care that autosave files for buffers not visiting any file (such | |
| 238 as `*mail*') from two simultaneous Emacses don't collide by prepending | |
| 239 the Emacs pid. | |
| 240 | |
| 241 Uses 14 character autosave names if `auto-save-hash-p' is true. | |

| 243 Autosaves even if the current directory is not writable, using | |
| 244 directory `auto-save-directory-fallback'. | |
