annotate src/lisp.h @ 5041:efaa6cd845e5
add regexp-debugging
-------------------- ChangeLog entries follow: --------------------
src/ChangeLog addition:
2010-02-15 Ben Wing <ben@xemacs.org>
* regex.c:
* regex.c (DEBUG_FAIL_PRINT1):
* regex.c (PUSH_FAILURE_POINT):
* regex.c (POP_FAILURE_POINT):
* regex.c (regex_compile):
* regex.c (re_match_2_internal):
* regex.h:
* search.c:
* search.c (search_buffer):
* search.c (debug_regexps_changed):
* search.c (vars_of_search):
Add an internal variable debug_regexps and a corresponding Lisp
variable `debug-regexps' that takes a list of areas in which to
display debugging info about regex compilation and matching
(currently three areas exist). Use existing debugging code
already in regex.c and modify it so that it recognizes the
debug_regexps variable and the flags in it.
Rename variable `debug-xemacs-searches' to just `debug-searches',
consistent with other debug vars.
tests/ChangeLog addition:
2010-02-15 Ben Wing <ben@xemacs.org>
* automated/search-tests.el (let):
* automated/search-tests.el (boundp):
debug-xemacs-searches renamed to debug-searches.

| 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 | |

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

| 498 g) [Bitbyte] a byte used for bit fields | |
| 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. | |
