* dynarr.c (Dynarr_insert_many):
* dynarr.c (Dynarr_delete_many):
* emacs.c:
* emacs.c (pause_so_user_can_read_messages):
* emacs.c (Fkill_emacs):
* emacs.c (guts_of_fatal_error_signal):
* lisp.h:
* lisp.h (INLINE_ERROR_CHECK_ARGS):
* lisp.h (Dynarr_set_length_1):
* lisp.h (Dynarr_set_length):
* lisp.h (Dynarr_pop):
Add ERROR_CHECK_DYNARR, dynarr_checking_assert(). Use it.
Sort existing error-check categories in lisp.h, remove most of the
(unused) assert variations from most categories. Add a long
comment about reorganizing the system by categories and
subcategories. Create ERROR_CHECK_ANY if any error-checking
categories defined, and use it in emacs.c to define
USER_IS_DEVELOPING_XEMACS.
In emacs.c and cmdloop.c, don't display a message at early
shutdown or fatal shutdown when on Cygwin, only Windows native --
Cygwin has a working stderr that shows error output.
Update comment in Dynarr_verify_pos_atp().

| 30 Based on code from pre-release FSF 19, c. 1991. | |
| 31 Various changes by Jamie Zawinski 1991-1994: | |
| 32 converting to ANSI C, splitting out function prototypes to a separate | |
| 33 file (later moved back for unknown reasons by Steve Baur?), debug-gcpro | |
| 34 stuff (now moribund). | |
| 35 ANSI-fication of DEFUN macros by Felix Lee, c. 1992? | |
| 36 NOT_REACHED, DOESNT_RETURN, PRINTF_ARGS by Richard Mlynarik, c. 1994. | |
| 37 Many changes over the years corresponding to Lisp_Object definition | |
| 38 changes, esp. by Richard Mlynarik (c. 1993) and Kyle Jones (c. 1998). | |
| 39 See alloc.c for more details. | |
| 40 Overhauled and reordered by Ben Wing, 1995-1996, and many things added: | |
| 41 Dynarrs, REALLOC macros, asserts, typedefs, inline header code, | |
| 42 first LIST_LOOP macros, CONCHECK_*, all error-checking code | |
| 43 (e.g. error-checking versions of XFOO macros), structure read syntax, | |
| 44 weak lists, lcrecord lists, reworking of quit handling, object hashing, | |
| 45 nested GCPRO, character objects and Ebola checking, memory usage stats, | |
| 46 others. | |
| 47 LOADHIST changes from Steve Baur, c. 1997? | |
| 48 Various macro-related changes by Martin Buchholz, 1998-1999: | |
| 49 LIST_LOOP macros greatly expanded and tortoise-hared; | |
| 50 RETURN_SANS_WARNINGS; reworked DEFUN macros; EXFUN macros (???). | |
| 1743 | 51 Various macro-related changes by Jerry James, 2003: |
| 52 MODULE_API introduced; | |
| 53 Compiler-specific definitions modernized and moved to compiler.h. | |

| 57 | |
| 58 "Mule-izing" is the process of going through a file and eliminating | |
| 59 assumptions that the internal format (Ibyte * text) is the same as the | |
| 60 external format used by library routines. Mule-ization should also | |
| 61 include replacing *ALL* raw references to `char' or `unsigned char' with | |
| 62 one of the self-documenting types created below. How exactly to do the | |
| 63 conversion, and how to write correctly Mule-ized code, is described in | |
| 64 the internals manual. Files that say "This file is Mule-ized" have | |
| 65 been reviewed at some point; that's not to say that incorrect code hasn't | |
| 66 crept in, though. | |
| 67 | |
| 68 "Unicode-splitting" is the process of fixing a file so that it will | |
| 69 handle external text in Unicode under Microsoft Windows, as appropriate. | |
| 70 ("splitting" because it needs to handle either Unicode or variable-width | |
| 71 multibyte depending on the OS -- NT or 9x). See intl-win32.c. | |
| 72 | |
| 73 #### is a way of marking problems of any sort. | |
| 74 | |
| 75 !!#### marks places that are not properly Mule-ized. | |
| 76 | |
| 77 &&#### marks places that need to be fixed in order for the "8-bit mule" | |
| 78 conversion to work correctly, i.e. in order to support multiple different | |
| 79 buffer formats under Mule, including a fixed 8-bit format. | |
| 80 | |
| 81 ^^#### marks places that need to be fixed in order to eliminate the | |
| 82 assumption that Ibyte * text is composed of 1-byte units (e.g. UTF-16 | |
| 83 is composed of 2-byte units and might be a possible format to consider | |
| 84 for Ibyte * text). | |
| 85 | |
| 86 %%#### marks places that need work for KKCC (the new garbage collector). | |

| 480 REMEMBER! These typedefs are purely for documentation purposes; from | |

| 488 | |
| 489 a) [Ibyte] pointer to internally-formatted text | |
| 490 b) [Extbyte] pointer to text in some external format, which can be | |

| 499 h) [Chbyte] null-semantics `char *'; used when casting an argument to | |

| 506 C = plain char, when the base type is unsigned | |

| 508 S = signed | |
| 509 | |
| 510 Ideally, XEmacs code should NEVER directly use `char' or any type | |
| 511 derived from it. This is for Mule-cleanliness. If you find yourself | |
| 512 wanting or needing to use `char' and one of the above six semantics does | |
| 513 not apply, add a new type of semantics; don't use `char' directly. | |

| 527 | |
| 2367 | 528 In general, you should avoid this where possible and use Ascbyte if the |

| 1291 /* Allocating excessively large blocks on the stack can cause crashes. | |
| 851 | 1292 We provide MALLOC_OR_ALLOCA() below for places where it's likely that |
| 1293 large amounts will be allocated; it mallocs the block if it's too big. | |
| 1294 Unfortunately, that requires a call to unbind_to() at the end of the | |
| 1295 function, and it's not feasible to rewrite all calls to alloca() this | |
| 1296 way. | |
| 1297 | |
| 1298 Instead, we use the portable C alloca() substitute in alloca.c above a | |
| 1299 certain size. This actually uses malloc(), but checks the current stack | |
| 1300 pointer to see if data from previous alloca() calls needs to be freed. | |
| 1301 However, this can lead to large heap sizes -- especially since cleanup | |
| 1302 can only happen in a parent function, and will never happen if (as will | |
| 1303 often be the case) it's the same function in the same place in the code | |
| 1304 that keeps tripping the alloca() limit. | |
| 1305 | |
| 1306 So we set up a system to periodically force cleanup. Currently we | |
| 1307 do cleanup: | |
| 1308 | |
| 1309 -- Only when there's C alloca() data, and then | |
| 1310 -- Every stack alloca() or allocation of Lisp data, every call to | |
| 1311 next_event_internal() [typically near the top of the stack], | |
| 1312 or every 10th funcall | |
| 1313 | |
| 1314 This should not be a big penalty because | |
| 1315 | |
| 1316 (a) If there are few C alloca() chunks, checking them will be fast | |
| 1317 (b) If not, we've allocated a huge amount of heap space (remember, each | |
| 1318 chunk represents > 256K of heap), and we really want them gone | |
| 1319 */ | |

| 1594 facilitate allocation, reallocation, etc. MALLOC_OVERHEAD is for | |
| 1595 memory allocated with malloc(); DYNARR_OVERHEAD is for dynamic | |
| 1596 arrays; GAP_OVERHEAD is for gap arrays. Note that for (e.g.) | |
| 1597 dynamic arrays, there is both MALLOC_OVERHEAD and DYNARR_OVERHEAD | |
| 1598 memory: The dynamic array allocates memory above and beyond what | |
| 1599 was asked of it, and when it in turns allocates memory using | |
| 1600 malloc(), malloc() allocates memory beyond what it was asked | |
| 1601 to allocate. | |
| 1602 | |
| 1603 Functions that accept a structure of this sort do not initialize | |
| 1604 the fields to 0, and add any existing values to whatever was there | |

| 2309 and executing code that you specify on each member of the list. | |
| 2310 | |
| 2311 There are two kinds of macros, those requiring surrounding braces, and | |
| 2312 those not requiring this. Which type of macro will be indicated. | |
| 2313 The general format for using a brace-requiring macro is | |
| 2314 | |
| 2315 { | |
| 2316 LIST_LOOP_3 (elt, list, tail) | |
| 2317 execute_code_here; | |
| 2318 } | |
| 2319 | |
| 2320 or | |
| 2321 | |
| 2322 { | |
| 2323 LIST_LOOP_3 (elt, list, tail) | |
| 2324 { | |
| 2325 execute_code_here; | |
| 2326 } | |
| 2327 } | |
| 2328 | |
| 2329 You can put variable declarations between the brace and beginning of | |
| 2330 macro, but NOTHING ELSE. | |
| 2331 | |
| 2332 The brace-requiring macros typically declare themselves any arguments | |
| 2333 that are initialized and iterated by the macros. If for some reason | |
| 2334 you need to declare these arguments yourself (e.g. to do something on | |
| 2335 them before the iteration starts, use the _NO_DECLARE versions of the | |
| 2336 macros.) | |
| 2337 */ | |
| 2338 | |
| 2339 /* There are two basic kinds of macros: those that handle "internal" lists | |
| 2340 that are known to be correctly structured (i.e. first element is a cons | |
| 2341 or nil, and the car of each cons is also a cons or nil, and there are | |
| 2342 no circularities), and those that handle "external" lists, where the | |
| 2343 list may have any sort of invalid formation. This is reflected in | |
| 2344 the names: those with "EXTERNAL_" work with external lists, and those | |
| 2345 without this prefix work with internal lists. The internal-list | |
| 2346 macros will hit an assertion failure if the structure is ill-formed; | |
| 2347 the external-list macros will signal an error in this case, either a | |
| 2348 malformed-list error or a circular-list error. | |
| 2349 */ | |

| 2367 | 2351 /* LIST_LOOP is a simple, old-fashioned macro. It doesn't require brace |
| 2352 surrounding, and iterates through a list, which may or may not known to | |
| 2353 be syntactically correct. It accepts two args, TAIL (set progressively | |
| 2354 to each cons starting with the first), and LIST, the list to iterate | |
| 2355 over. TAIL needs to be defined by the caller. | |
| 442 | 2356 |
| 2357 In each iteration, you can retrieve the current list item using XCAR | |
| 2358 (tail), or destructively modify the list using XSETCAR (tail, | |

| 2369 | |
| 2370 LIST_LOOP_2 and EXTERNAL_LIST_LOOP_2 are the standard, most-often used | |
| 2371 macros. They take two arguments, an element variable ELT and the list | |
| 2372 LIST. ELT is automatically declared, and set to each element in turn | |
| 2373 from LIST. | |
| 2374 | |
| 2375 LIST_LOOP_3 and EXTERNAL_LIST_LOOP_3 are the same, but they have a third | |
| 2376 argument TAIL, another automatically-declared variable. At each iteration, | |
| 2377 this one points to the cons cell for which ELT is the car. | |
| 2378 | |
| 2379 EXTERNAL_LIST_LOOP_4 is like EXTERNAL_LIST_LOOP_3 but takes an additional | |
| 2380 LEN argument, again automatically declared, which counts the number of | |
| 2381 iterations gone by. It is 0 during the first iteration. | |
| 2382 | |
| 2383 EXTERNAL_LIST_LOOP_4_NO_DECLARE is like EXTERNAL_LIST_LOOP_4 but none | |
| 2384 of the variables are automatically declared, and so you need to declare | |
| 2385 them yourself. (ELT and TAIL are Lisp_Objects, and LEN is an EMACS_INT.) | |

| 771 | 3934 /* When support for message translation exists, GETTEXT() translates a |
| 3935 string from English into the language defined by | |
| 3936 `current-language-environment'. This is done by looking the string | |
| 3937 up in a large predefined table; if no translation is found, the | |
| 3938 original string is returned, and the failure is possibly logged so | |
| 3939 that the translation can later be entered into the table. | |
| 3940 | |
| 3941 In addition to this, there is a mechanism to snarf message strings | |
| 3942 out of the source code so that they can be entered into the tables. | |
| 3943 This is what make-msgfile.lex does. | |
| 3944 | |
| 3945 Handling `format' strings is more difficult: The format string | |
| 3946 should get translated, but not under all circumstances. When the | |
| 3947 format string is a Lisp string, what should happen is that | |
| 3948 Fformat() should format the untranslated args[0] and return that, | |
| 3949 and also call Fgettext() on args[0] and, if that is different, | |
| 3950 format it and store it in the `string-translatable' property of the | |
| 3951 returned string. See Fgettext(). | |

| 1204 | 4070 /* #### Catching insufficient gcpro: |
| 4071 | |
| 4072 The C++ code below catches GCPRO without UNGCPRO or vice-versa. | |
| 4073 Catching cases where there's no GCPRO or UNGCPRO but should be, however, | |
| 4074 is much harder, but could be done: | |
| 4075 | |
| 4076 1. Lisp_Object becomes a real object. Its creator and destructor need to | |
| 4077 figure out whether the object is on the stack (by looking at the range | |
| 4078 that `this' is within), and if so, add the pointer to a list of all | |
| 4079 stack-based Lisp_Objects. | |
| 4080 | |
| 4081 2. The assignment method needs to do reference-counting on actual Lisp | |
| 4082 objects -- in particular, we need to know if there are any references | |
| 4083 to a Lisp object that are *NOT* from stack-based Lisp_Objects. | |
| 4084 | |
| 4085 3. When we get to a point in the code where we might garbage collect -- | |
| 4086 i.e. Ffuncall(), Feval(), or Fgarbage_collect() is called -- we look | |
| 4087 at our list of stack-based Lisp_Objects, and if there are any that | |
| 4088 point to Lisp objects with no non-stack references, see if there are | |
| 4089 any gcpros pointing to the object, and if not, set a flag indicating | |
| 4090 that the object is "destroyed". (Don't abort yet because the function | |
| 4091 might not use the object any more.) | |
| 4092 | |
| 4093 4. When we detag a pointer using XFOO(), abort if its "destroyed" flag | |
| 4094 is set. | |
