try harder to avoid crashing when debug-printing
-------------------- ChangeLog entries follow: --------------------
src/ChangeLog addition:
2010-01-18 Ben Wing <ben@xemacs.org>
* lisp.h:
* print.c:
New variable `in_debug_print'.
* alloc.c:
* alloc.c (free_managed_lcrecord):
If gc_in_progress and in_debug_print, just return instead of
crashing. This only happens when the programmer calls debug_print()
or a variation inside of a debugger, and is probably already
diagnosing a crash.
* print.c (struct debug_bindings):
* print.c (debug_prin1_exit):
* print.c (debug_prin1):
At entrance, record the old value of in_debug_print in the
debug_bindings, set up an unwind-protect to restore the old value,
and set in_debug_print to 1. In the unwind-protect, restore the
old value.

| 27 Based on code from pre-release FSF 19, c. 1991. | |
| 28 Various changes by Jamie Zawinski 1991-1994: | |
| 29 converting to ANSI C, splitting out function prototypes to a separate | |
| 30 file (later moved back for unknown reasons by Steve Baur?), debug-gcpro | |
| 31 stuff (now moribund). | |
| 32 ANSI-fication of DEFUN macros by Felix Lee, c. 1992? | |
| 33 NOT_REACHED, DOESNT_RETURN, PRINTF_ARGS by Richard Mlynarik, c. 1994. | |
| 34 Many changes over the years corresponding to Lisp_Object definition | |
| 35 changes, esp. by Richard Mlynarik (c. 1993) and Kyle Jones (c. 1998). | |
| 36 See alloc.c for more details. | |
| 37 Overhauled and reordered by Ben Wing, 1995-1996, and many things added: | |
| 38 Dynarrs, REALLOC macros, asserts, typedefs, inline header code, | |
| 39 first LIST_LOOP macros, CONCHECK_*, all error-checking code | |
| 40 (e.g. error-checking versions of XFOO macros), structure read syntax, | |
| 41 weak lists, lcrecord lists, reworking of quit handling, object hashing, | |
| 42 nested GCPRO, character objects and Ebola checking, memory usage stats, | |
| 43 others. | |
| 44 LOADHIST changes from Steve Baur, c. 1997? | |
| 45 Various macro-related changes by Martin Buchholz, 1998-1999: | |
| 46 LIST_LOOP macros greatly expanded and tortoise-hared; | |
| 47 RETURN_SANS_WARNINGS; reworked DEFUN macros; EXFUN macros (???). | |
| 1743 | 48 Various macro-related changes by Jerry James, 2003: |
| 49 MODULE_API introduced; | |
| 50 Compiler-specific definitions modernized and moved to compiler.h. | |

| 61 | |
| 62 "Mule-izing" is the process of going through a file and eliminating | |
| 63 assumptions that the internal format (Ibyte * text) is the same as the | |
| 64 external format used by library routines. Mule-ization should also | |
| 65 include replacing *ALL* raw references to `char' or `unsigned char' with | |
| 66 one of the self-documenting types created below. How exactly to do the | |
| 67 conversion, and how to write correctly Mule-ized code, is described in | |
| 68 the internals manual. Files that say "This file is Mule-ized" have | |
| 69 been reviewed at some point; that's not to say that incorrect code hasn't | |
| 70 crept in, though. | |
| 71 | |
| 72 "Unicode-splitting" is the process of fixing a file so that it will | |
| 73 handle external text in Unicode under Microsoft Windows, as appropriate. | |
| 74 ("splitting" because it needs to handle either Unicode or variable-width | |
| 75 multibyte depending on the OS -- NT or 9x). See intl-win32.c. | |
| 76 | |
| 77 #### is a way of marking problems of any sort. | |
| 78 | |
| 79 !!#### marks places that are not properly Mule-ized. | |
| 80 | |
| 81 &&#### marks places that need to be fixed in order for the "8-bit mule" | |
| 82 conversion to work correctly, i.e. in order to support multiple different | |
| 83 buffer formats under Mule, including a fixed 8-bit format. | |
| 84 | |
| 85 ^^#### marks places that need to be fixed in order to eliminate the | |
| 86 assumption that Ibyte * text is composed of 1-byte units (e.g. UTF-16 | |
| 87 is composed of 2-byte units and might be a possible format to consider | |
| 88 for Ibyte * text). | |
| 89 | |
| 90 %%#### marks places that need work for KKCC (the new garbage collector). | |

| 500 | |
| 501 /* The definitions we put here and in the next section use typedefs to | |
| 502 attribute specific meaning to types that by themselves are pretty | |
| 503 general. | |
| 504 | |
| 505 REMEMBER! These typedefs are purely for documentation purposes; from | |
| 647 | 506 the C code's perspective, they are exactly equivalent to `char *', |
| 507 `unsigned char *', etc., so you can freely use them with library | |
| 2367 | 508 functions declared as such. |
| 509 | |
| 510 (See also "Byte/Character Types" in text.c) | |
| 511 | |
| 512 The basic semantics for `char': | |
| 513 | |
| 514 a) [Ibyte] pointer to internally-formatted text | |
| 515 b) [Extbyte] pointer to text in some external format, which can be | |
| 516 defined as all formats other than the internal one | |
| 517 c) [Ascbyte] pure ASCII text | |
| 518 d) [Binbyte] binary data that is not meant to be interpreted as text | |
| 519 e) [Rawbyte] general data in memory, where we don't care about whether | |
| 520 it's text or binary | |
| 521 f) [Boolbyte] a zero or a one | |
| 522 g) [Bitbyte] a byte used for bit fields | |
| 523 h) [Chbyte] null-semantics `char *'; used when casting an argument to | |
| 524 an external API where the the other types may not be | |
| 525 appropriate | |
| 526 | |
| 527 | |
| 528 Prefixing codes: | |
| 529 | |
| 530 C = plain char, when the base type is unsigned | |
| 531 U = unsigned | |
| 532 S = signed | |
| 533 | |
| 534 Ideally, XEmacs code should NEVER directly use `char' or any type | |
| 535 derived from it. This is for Mule-cleanliness. If you find yourself | |
| 536 wanting or needing to use `char' and one of the above six semantics does | |
| 537 not apply, add a new type of semantics; don't use `char' directly. | |

| 851 | 1319 We provide MALLOC_OR_ALLOCA() below for places where it's likely that |
| 1320 large amounts will be allocated; it mallocs the block if it's too big. | |
| 1321 Unfortunately, that requires a call to unbind_to() at the end of the | |
| 1322 function, and it's not feasible to rewrite all calls to alloca() this | |
| 1323 way. | |
| 1324 | |
| 1325 Instead, we use the portable C alloca() substitute in alloca.c above a | |
| 1326 certain size. This actually uses malloc(), but checks the current stack | |
| 1327 pointer to see if data from previous alloca() calls needs to be freed. | |
| 1328 However, this can lead to large heap sizes -- especially since cleanup | |
| 1329 can only happen in a parent function, and will never happen if (as will | |
| 1330 often be the case) it's the same function in the same place in the code | |
| 1331 that keeps tripping the alloca() limit. | |
| 1332 | |
| 1333 So we set up a system to periodically force cleanup. Currently we | |
| 1334 do cleanup: | |
| 1335 | |
| 1336 -- Only when there's C alloca() data, and then | |
| 1337 -- Every stack alloca() or allocation of Lisp data, every call to | |
| 1338 next_event_internal() [typically near the top of the stack], | |
| 1339 or every 10th funcall | |
| 1340 | |
| 1341 This should not be a big penalty because | |
| 1342 | |
| 1343 (a) If there are few C alloca() chunks, checking them will be fast | |
| 1344 (b) If not, we've allocated a huge amount of heap space (remember, each | |
| 1345 chunk represents > 256K of heap), and we really want them gone | |

| 2215 and executing code that you specify on each member of the list. | |
| 2216 | |
| 2217 There are two kinds of macros, those requiring surrounding braces, and | |
| 2218 those not requiring this. Which type of macro will be indicated. | |
| 2219 The general format for using a brace-requiring macro is | |
| 2220 | |
| 2221 { | |
| 2222 LIST_LOOP_3 (elt, list, tail) | |
| 2223 execute_code_here; | |
| 2224 } | |
| 2225 | |
| 2226 or | |
| 2227 | |
| 2228 { | |
| 2229 LIST_LOOP_3 (elt, list, tail) | |
| 2230 { | |
| 2231 execute_code_here; | |
| 2232 } | |
| 2233 } | |
| 2234 | |
| 2235 You can put variable declarations between the brace and beginning of | |
| 2236 macro, but NOTHING ELSE. | |
| 2237 | |
| 2238 The brace-requiring macros typically declare themselves any arguments | |
| 2239 that are initialized and iterated by the macros. If for some reason | |
| 2240 you need to declare these arguments yourself (e.g. to do something on | |
| 2241 them before the iteration starts, use the _NO_DECLARE versions of the | |
| 2242 macros.) | |
| 2243 */ | |
| 2244 | |
| 2245 /* There are two basic kinds of macros: those that handle "internal" lists | |
| 2246 that are known to be correctly structured (i.e. first element is a cons | |
| 2247 or nil, and the car of each cons is also a cons or nil, and there are | |
| 2248 no circularities), and those that handle "external" lists, where the | |
| 2249 list may have any sort of invalid formation. This is reflected in | |
| 2250 the names: those with "EXTERNAL_" work with external lists, and those | |
| 2251 without this prefix work with internal lists. The internal-list | |
| 2252 macros will hit an assertion failure if the structure is ill-formed; | |
| 2253 the external-list macros will signal an error in this case, either a | |
| 2254 malformed-list error or a circular-list error. | |
| 2255 */ | |
| 2256 | |
| 2367 | 2257 /* LIST_LOOP is a simple, old-fashioned macro. It doesn't require brace |
| 2258 surrounding, and iterates through a list, which may or may not known to | |
| 2259 be syntactically correct. It accepts two args, TAIL (set progressively | |
| 2260 to each cons starting with the first), and LIST, the list to iterate | |
| 2261 over. TAIL needs to be defined by the caller. | |
| 442 | 2262 |
| 2263 In each iteration, you can retrieve the current list item using XCAR | |

| 2275 | |
| 2276 LIST_LOOP_2 and EXTERNAL_LIST_LOOP_2 are the standard, most-often used | |
| 2277 macros. They take two arguments, an element variable ELT and the list | |

| 2279 from LIST. | |
| 2280 | |
| 2281 LIST_LOOP_3 and EXTERNAL_LIST_LOOP_3 are the same, but they have a third | |
| 2282 argument TAIL, another automatically-declared variable. At each iteration, | |
| 2283 this one points to the cons cell for which ELT is the car. | |
| 2284 | |
| 2285 EXTERNAL_LIST_LOOP_4 is like EXTERNAL_LIST_LOOP_3 but takes an additional | |
| 2286 LEN argument, again automatically declared, which counts the number of | |
| 2287 iterations gone by. It is 0 during the first iteration. | |
| 2288 | |
