[xemacs-hg @ 2003-01-12 11:07:58 by michaels] modules/ChangeLog: 2002-12-16 Ben Wing <ben@xemacs.org> * postgresql/postgresql.c: 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. * README.kkcc: * alloc.c: * alloc.c (deadbeef_memory): * alloc.c (allocate_lisp_storage): * alloc.c (copy_lisp_object): * alloc.c

/* Written by Howard Gayle. */

/* The four tables in a case table are downcase, upcase, canon, and eqv.
   Each is a char-table.  Their workings are rather non-obvious.

   (1) `downcase' is the only obvious table: Map a character to its
   lowercase equivalent.

   (2) `upcase' does *NOT* map a character to its uppercase equivalent,
   despite its name.  Rather, it maps lowercase characters to their
   uppercase equivalent, and uppercase characters to *ANYTHING BUT* their
   uppercase equivalent (currently, their lowercase equivalent), and
   characters without case to themselves.  It is used to determine if a
   character "has no case" (no uppercase or lowercase mapping). #### This
   is way bogus.  Just use the obvious implementation of uppercase mapping
   and of NOCASE_P.

   (3) `canon' maps each character to a "canonical" lowercase, such that if
   two different uppercase characters map to the same lowercase character,
   or vice versa, both characters will have the same entry in the canon
   table.

   (4) `equiv' lists the "equivalence classes" defined by `canon'.  Imagine
   that all characters are divided into groups having the same `canon'
   entry; these groups are called "equivalence classes" and `equiv' lists
   them by linking the characters in each equivalence class together in a
   circular list.

   `canon' is used when doing case-insensitive comparisons.  `equiv' is
   used in the Boyer-Moore search code.

Select CASE-TABLE as the new case table for the current buffer.
A case table is a case-table object or list
 (DOWNCASE UPCASE CANONICALIZE EQUIVALENCES)
 where each element is either nil or a string of length 256.
The latter is provided for backward-compatibility.
DOWNCASE maps each character to its lower-case equivalent.
UPCASE maps each character to its upper-case equivalent;
 if lower and upper case characters are in 1-1 correspondence,
 you may use nil and the upcase table will be deduced from DOWNCASE.
CANONICALIZE maps each character to a canonical equivalent;
 any two characters that are related by case-conversion have the same
 canonical equivalent character; it may be nil, in which case it is
 deduced from DOWNCASE and UPCASE.
EQUIVALENCES is a map that cyclicly permutes each equivalence class
 (of characters with the same canonical equivalent); it may be nil,
 in which case it is deduced from CANONICALIZE.
