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.

* 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.

| 34 "Alist to decide a coding system to use for a process I/O operation. | |
| 35 The format is ((PATTERN . VAL) ...), | |
| 36 where PATTERN is a regular expression matching a program name, | |
| 37 VAL is a coding system, a cons of coding systems, or a function symbol. | |
| 38 If VAL is a coding system, it is used for both decoding what received | |
| 39 from the program and encoding what sent to the program. | |
| 40 If VAL is a cons of coding systems, the car part is used for decoding, | |
| 41 and the cdr part is used for encoding. | |
| 853 | 42 If VAL is a function symbol, it is called with two arguments, a symbol |
| 43 indicating the operation being performed (one of `start-process', | |
| 44 `call-process', `open-network-stream', or `open-multicast-group') and the | |
| 45 program name. The function must return a coding system or a cons of | |
| 46 coding systems which are used as above.") | |

| 48 (defun call-process (program &optional infile buffer displayp &rest args) | |
| 49 "Call PROGRAM synchronously in separate process. | |
| 853 | 50 |
| 428 | 51 The program's input comes from file INFILE (nil means `/dev/null'). |
| 853 | 52 XEmacs feature: INFILE can also be a list of (BUFFER [START [END]]), i.e. |
| 53 a list of one to three elements, consisting of a buffer and optionally | |
| 54 a start position or start and end position. In this case, input comes | |
| 55 from the buffer, starting from START (defaults to the beginning of the | |
| 56 buffer) and ending at END (defaults to the end of the buffer). | |
| 57 | |
| 428 | 58 Insert output in BUFFER before point; t means current buffer; |
| 59 nil for BUFFER means discard it; 0 means discard and don't wait. | |
| 837 | 60 If BUFFER is a string, then find or create a buffer with that name, |
| 61 then insert the output in that buffer, before point. | |
| 428 | 62 BUFFER can also have the form (REAL-BUFFER STDERR-FILE); in that case, |
| 63 REAL-BUFFER says what to do with standard output, as above, | |
| 64 while STDERR-FILE says what to do with standard error in the child. | |
| 65 STDERR-FILE may be nil (discard standard error output), | |
| 853 | 66 t (mix it with ordinary output), a file name string, or (XEmacs feature) |
| 67 a buffer object. If STDERR-FILE is a buffer object (but not the name of | |
| 68 a buffer, since that would be interpreted as a file), the standard error | |
| 69 output will be inserted into the buffer before point. | |
| 428 | 70 |
| 853 | 71 Fourth arg DISPLAY non-nil means redisplay buffer as output is inserted. |
| 428 | 72 Remaining arguments are strings passed as command arguments to PROGRAM. |
| 73 | |
| 853 | 74 If BUFFER is 0, returns immediately with value nil. |
| 75 Otherwise waits for PROGRAM to terminate and returns a numeric exit status | |
| 76 or a signal description string. If you quit, the process is first killed | |
| 77 with SIGINT, then with SIGKILL if you quit again before the process exits. | |
| 78 | |
| 79 If INFILE is a file, we transfer its exact contents to the process without | |
| 80 any encoding/decoding. (#### This policy might change.) | |
| 81 | |
| 82 Otherwise, the read/write coding systems used for process I/O on the | |
| 83 process are determined as follows: | |
| 84 | |
| 85 1. `coding-system-for-read', `coding-system-for-write', if non-nil. | |
| 86 (Intended as a temporary overriding mechanism for use by Lisp | |
| 87 code.) | |
| 88 2. The matching value for the process name from `process-coding-system-alist', | |
| 89 if any, and if non-nil. The value may be either a single coding | |
| 90 system, used for both read and write; or a cons of read/write; or a | |
| 91 function, called to get one of the other two values. | |
| 92 3. For writing: If a buffer was given in INFILE, the value of | |
| 93 `buffer-file-coding-system' in that buffer. | |
| 94 For reading: if a buffer was given in BUFFER, the value of | |
| 95 `buffer-file-coding-system-for-read' in that buffer. | |
| 96 4. The value of `default-process-coding-system', which should be a cons | |
| 97 of read/write coding systems, if the values are non-nil. | |
| 98 5. The coding system `undecided' for read, and `raw-text' for write. | |
| 99 | |
| 100 Note that the processes of determining the read and write coding systems | |
| 101 proceed essentially independently one from the other, as in `start-process'." | |

| 206 (Intended as a temporary overriding mechanism for use by Lisp | |
| 207 code.) | |
| 208 2. The matching value for the process name from `process-coding-system-alist', | |
| 209 if any, and if non-nil. The value may be either a single coding | |
| 210 system, used for both read and write; or a cons of read/write; or a | |
| 211 function, called to get one of the other two values. | |
| 212 3. The value of `default-process-coding-system', which should be a cons | |
| 213 of read/write coding systems, if the values are non-nil. | |
| 214 4. The coding system `undecided' for read, and `raw-text' for write. | |
| 215 | |
| 216 Note that the processes of determining the read and write coding systems | |
| 217 proceed essentially independently one from the other. For example, a value | |
| 218 determined from `process-coding-system-alist' might specify a read coding | |
| 219 system but not a write coding system, in which the read coding system is as | |
| 220 specified and the write coding system comes from proceeding to step 3 (and | |
| 221 looking in `default-process-coding-system'). | |
| 222 | |
| 223 You can change the coding systems later on using | |
| 224 `set-process-coding-system', `set-process-input-coding-system', or | |
| 225 `set-process-output-coding-system'. | |
