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.

| 18 /* Synched up with: Not in FSF. */ | |
| 19 | |
| 20 /* Debugging hooks for malloc. */ | |
| 21 | |
| 22 /* These hooks work with gmalloc to catch allocation errors. | |
| 23 In particular, the following is trapped: | |
| 24 | |
| 25 * Freeing the same pointer twice. | |
| 26 * Trying to free a pointer not returned by malloc. | |
| 27 * Trying to realloc a pointer not returned by malloc. | |
| 28 | |
| 1204 | 29 In addition, every word of every block freed is set to 0xdeadbeef |
| 30 (-559038737). This causes many uses of freed storage to be trapped or | |
| 31 recognized. | |
| 428 | 32 |
| 33 When you use this, the storage used by the last FREE_QUEUE_LIMIT | |
| 34 calls to free() is not recycled. When you call free for the Nth | |
| 35 time, the (N - FREE_QUEUE_LIMIT)'th block is actually recycled. | |
| 36 | |
| 37 For these last FREE_QUEUE_LIMIT calls to free() a backtrace is | |
| 38 saved showing where it was called from. The function | |
| 39 find_backtrace() is provided here to be called from GDB with a | |
| 40 pointer (such as would be passed to free()) as argument, e.g. | |
| 41 (gdb) p/a *find_backtrace (0x234000). If SAVE_ARGS is defined, | |
| 42 the first three arguments to each function are saved as well as the | |
| 43 return addresses. | |
| 44 | |
| 45 If UNMAPPED_FREE is defined, instead of setting every word of freed | |
| 46 storage to 0xdeadbeef, every call to malloc goes on its own page(s). | |
| 47 When free() is called, the block is read and write protected. This | |
| 48 is very useful when debugging, since it usually generates a bus error | |
| 49 when the deadbeef hack might only cause some garbage to be printed. | |
| 50 However, this is too slow for everyday use, since it takes an enormous | |
| 51 number of pages. | |
| 52 | |
| 53 | |
| 54 Some other features that would be useful are: | |
| 55 | |
| 56 * Checking for storage leaks. | |
| 57 This could be done by a GC-like facility that would scan the data | |
| 58 segment looking for pointers to allocated storage and tell you | |
| 59 about those that are no longer referenced. This could be invoked | |
| 60 at any time. Another possibility is to report on what allocated | |
| 61 storage is still in use when the process is exited. Typically | |
| 62 there will be a large amount, so this might not be very useful. | |
