| 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). | |
| 87 | |
| 5090 | 88 @@#### marks places that need work to get Unicode-internal working, |
| 89 i.e. using UTF-8 as the internal text format. | |
| 90 | |
| 91 #### BILL! marks places that need work for GTK. | |
| 92 | |
| 93 #### GEOM! marks places needing work to fix various bugs in the handling | |
| 94 of window and frame sizing and positioning. Often the root of the | |
| 95 problems is that the code was originally written before there was a | |
| 96 gutter and then not completely fixed up to accommodate the gutter. | |

| 1310 /* Allocating excessively large blocks on the stack can cause crashes. | |
| 851 | 1311 We provide MALLOC_OR_ALLOCA() below for places where it's likely that |
| 1312 large amounts will be allocated; it mallocs the block if it's too big. | |
| 1313 Unfortunately, that requires a call to unbind_to() at the end of the | |
| 1314 function, and it's not feasible to rewrite all calls to alloca() this | |
| 1315 way. | |
| 1316 | |
| 1317 Instead, we use the portable C alloca() substitute in alloca.c above a | |
| 1318 certain size. This actually uses malloc(), but checks the current stack | |
| 1319 pointer to see if data from previous alloca() calls needs to be freed. | |
| 1320 However, this can lead to large heap sizes -- especially since cleanup | |
| 1321 can only happen in a parent function, and will never happen if (as will | |
| 1322 often be the case) it's the same function in the same place in the code | |
| 1323 that keeps tripping the alloca() limit. | |
| 1324 | |
| 1325 So we set up a system to periodically force cleanup. Currently we | |
| 1326 do cleanup: | |
| 1327 | |
| 1328 -- Only when there's C alloca() data, and then | |
| 1329 -- Every stack alloca() or allocation of Lisp data, every call to | |
| 1330 next_event_internal() [typically near the top of the stack], | |
| 1331 or every 10th funcall | |
| 1332 | |
| 1333 This should not be a big penalty because | |
| 1334 | |
| 1335 (a) If there are few C alloca() chunks, checking them will be fast | |
| 1336 (b) If not, we've allocated a huge amount of heap space (remember, each | |
| 1337 chunk represents > 256K of heap), and we really want them gone | |
| 1338 */ | |
| 1339 | |

| 1786 | |
| 5038 | 1787 /* Dynarr locking and verification. |
| 1788 | |
| 1789 [I] VERIFICATION | |
| 1790 | |
| 1791 Verification routines simply return their basic argument, possibly | |
| 1792 casted, but in the process perform some verification on it, aborting if | |
| 1793 the verification fails. The verification routines take FILE and LINE | |
| 1794 parameters, and use them to output the file and line of the caller | |
| 1795 when an abort occurs, rather than the file and line of the inline | |
| 1796 function, which is less than useful. | |
| 1797 | |
| 1798 There are three basic types of verification routines: | |
| 1799 | |
| 1800 (1) Verify the dynarr itself. This verifies the basic invariant | |
| 1801 involving the length/size values: | |
| 1802 | |
| 1803 0 <= Dynarr_length(d) <= Dynarr_largest(d) <= Dynarr_max(d) | |
| 1804 | |
| 1805 (2) Verify the dynarr itself prior to modifying it. This performs | |
| 1806 the same verification as previously, but also checks that the | |
| 1807 dynarr is not locked (see below). | |
| 1808 | |
| 1809 (3) Verify a dynarr position. Unfortunately we have to have | |
| 1810 different verification routines depending on which kind of operation | |
| 1811 is being performed: | |
| 1812 | |
| 1813 (a) For Dynarr_at(), we check that the POS is bounded by Dynarr_largest(), | |
| 1814 i.e. 0 <= POS < Dynarr_largest(). | |
| 1815 (b) For Dynarr_atp_allow_end(), we also have to allow | |
| 1816 POS == Dynarr_largest(). | |
| 1817 (c) For Dynarr_atp(), we behave largely like Dynarr_at() but make a | |
| 1818 special exception when POS == 0 and Dynarr_largest() == 0 -- see | |
| 1819 comment below. | |
| 1820 (d) Some other routines contain the POS verification within their code, | |
| 1821 and make the check 0 <= POS < Dynarr_length() or | |
| 1822 0 <= POS <= Dynarr_length(). | |
| 1823 | |
| 1824 #### It is not well worked-out whether and in what circumstances it's | |
| 1825 allowed to use a position that is between Dynarr_length() and | |
| 1826 Dynarr_largest(). The ideal solution is to never allow this, and require | |
| 1827 instead that code first change the length before accessing higher | |
| 1828 positions. That would require looking through all the code that accesses | |
| 1829 dynarrs and fixing it appropriately (especially redisplay code, and | |
| 1830 especially redisplay code in the vicinity of a reference to | |
| 1831 Dynarr_largest(), since such code usually checks explicitly to see whether | |
| 1832 there is extra stuff between Dynarr_length() and Dynarr_largest().) | |
| 1833 | |
| 1834 [II] LOCKING | |
| 1835 | |
| 1836 The idea behind dynarr locking is simple: Locking a dynarr prevents | |
| 1837 any modification from occurring, or rather, leads to an abort upon | |
| 1838 any attempt to modify a dynarr. | |
| 1839 | |
| 1840 Dynarr locking was originally added to catch some sporadic and hard-to- | |
| 1841 debug crashes in the redisplay code where dynarrs appeared to be getting | |
| 1842 corrupted in an unexpected fashion. The solution was to lock the | |
| 1843 dynarrs that were getting corrupted (in this case, the display-line | |
| 1844 dynarrs) around calls to routines that weren't supposed to be changing | |
| 1845 these dynarrs but might somehow be calling code that modified them. | |
| 1846 This eventually revealed that there was a reentrancy problem with | |
| 1847 redisplay that involved the QUIT mechanism and the processing done in | |
| 1848 order to determine whether C-g had been pressed -- this processing | |
| 1849 involves retrieving, processing and queueing pending events to see | |
| 1850 whether any of them result in a C-g keypress. However, at least under | |
| 1851 MS Windows this can result in redisplay being called reentrantly. | |

| 442 | 2540 /*---------------------- list traversal macros -------------------------*/ |
| 2541 | |
| 2542 /* Note: These macros are for traversing through a list in some format, | |
| 2543 and executing code that you specify on each member of the list. | |
| 2544 | |
| 2545 There are two kinds of macros, those requiring surrounding braces, and | |
| 2546 those not requiring this. Which type of macro will be indicated. | |
| 2547 The general format for using a brace-requiring macro is | |
| 2548 | |
| 2549 { | |
| 2550 LIST_LOOP_3 (elt, list, tail) | |
| 2551 execute_code_here; | |
| 2552 } | |
| 2553 | |
| 2554 or | |
| 2555 | |
| 2556 { | |
| 2557 LIST_LOOP_3 (elt, list, tail) | |
| 2558 { | |
| 2559 execute_code_here; | |
| 2560 } | |
| 2561 } | |
| 2562 | |
| 2563 You can put variable declarations between the brace and beginning of | |
| 2564 macro, but NOTHING ELSE. | |
| 2565 | |
| 2566 The brace-requiring macros typically declare themselves any arguments | |
| 2567 that are initialized and iterated by the macros. If for some reason | |
| 2568 you need to declare these arguments yourself (e.g. to do something on | |
| 2569 them before the iteration starts, use the _NO_DECLARE versions of the | |
| 2570 macros.) | |
| 2571 */ | |
| 2572 | |
| 2573 /* There are two basic kinds of macros: those that handle "internal" lists | |
| 2574 that are known to be correctly structured (i.e. first element is a cons | |
| 2575 or nil, and the car of each cons is also a cons or nil, and there are | |
| 2576 no circularities), and those that handle "external" lists, where the | |
| 2577 list may have any sort of invalid formation. This is reflected in | |
| 2578 the names: those with "EXTERNAL_" work with external lists, and those | |
| 2579 without this prefix work with internal lists. The internal-list | |
| 2580 macros will hit an assertion failure if the structure is ill-formed; | |
| 2581 the external-list macros will signal an error in this case, either a | |
| 2582 malformed-list error or a circular-list error. | |
| 2583 */ | |
| 2584 | |
| 2367 | 2585 /* LIST_LOOP is a simple, old-fashioned macro. It doesn't require brace |
| 2586 surrounding, and iterates through a list, which may or may not known to | |
| 2587 be syntactically correct. It accepts two args, TAIL (set progressively | |
| 2588 to each cons starting with the first), and LIST, the list to iterate | |
| 2589 over. TAIL needs to be defined by the caller. | |
| 442 | 2590 |

| 2603 | |
| 2604 LIST_LOOP_2 and EXTERNAL_LIST_LOOP_2 are the standard, most-often used | |
| 2605 macros. They take two arguments, an element variable ELT and the list | |
| 2606 LIST. ELT is automatically declared, and set to each element in turn | |
| 2607 from LIST. | |
| 2608 | |
| 2609 LIST_LOOP_3 and EXTERNAL_LIST_LOOP_3 are the same, but they have a third | |
| 2610 argument TAIL, another automatically-declared variable. At each iteration, | |
| 2611 this one points to the cons cell for which ELT is the car. | |
| 2612 | |
| 2613 EXTERNAL_LIST_LOOP_4 is like EXTERNAL_LIST_LOOP_3 but takes an additional | |
| 2614 LEN argument, again automatically declared, which counts the number of | |
| 2615 iterations gone by. It is 0 during the first iteration. | |
| 2616 | |

| 2618 of the variables are automatically declared, and so you need to declare | |
| 2619 them yourself. (ELT and TAIL are Lisp_Objects, and LEN is an EMACS_INT.) | |

| 771 | 4256 /* When support for message translation exists, GETTEXT() translates a |
| 4257 string from English into the language defined by | |
| 4258 `current-language-environment'. This is done by looking the string | |
| 4259 up in a large predefined table; if no translation is found, the | |
| 4260 original string is returned, and the failure is possibly logged so | |
| 4261 that the translation can later be entered into the table. | |
| 4262 | |
| 4263 In addition to this, there is a mechanism to snarf message strings | |
| 4264 out of the source code so that they can be entered into the tables. | |
| 4265 This is what make-msgfile.lex does. | |
| 4266 | |
| 4267 Handling `format' strings is more difficult: The format string | |
| 4268 should get translated, but not under all circumstances. When the | |
| 4269 format string is a Lisp string, what should happen is that | |
| 4270 Fformat() should format the untranslated args[0] and return that, | |
| 4271 and also call Fgettext() on args[0] and, if that is different, | |
| 4272 format it and store it in the `string-translatable' property of the | |
| 4273 returned string. See Fgettext(). | |

| 4393 | |
| 4394 The C++ code below catches GCPRO without UNGCPRO or vice-versa. | |
| 4395 Catching cases where there's no GCPRO or UNGCPRO but should be, however, | |
| 4396 is much harder, but could be done: | |
| 4397 | |
| 4398 1. Lisp_Object becomes a real object. Its creator and destructor need to | |
| 4399 figure out whether the object is on the stack (by looking at the range | |
| 4400 that `this' is within), and if so, add the pointer to a list of all | |
| 4401 stack-based Lisp_Objects. | |
| 4402 | |
| 4403 2. The assignment method needs to do reference-counting on actual Lisp | |
| 4404 objects -- in particular, we need to know if there are any references | |
| 4405 to a Lisp object that are *NOT* from stack-based Lisp_Objects. | |
| 4406 | |
| 4407 3. When we get to a point in the code where we might garbage collect -- | |
| 4408 i.e. Ffuncall(), Feval(), or Fgarbage_collect() is called -- we look | |
| 4409 at our list of stack-based Lisp_Objects, and if there are any that | |
| 4410 point to Lisp objects with no non-stack references, see if there are | |
| 4411 any gcpros pointing to the object, and if not, set a flag indicating | |
| 4412 that the object is "destroyed". (Don't abort yet because the function | |
| 4413 might not use the object any more.) | |
| 4414 | |
| 4415 4. When we detag a pointer using XFOO(), abort if its "destroyed" flag | |
| 4416 is set. | |
