| 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). | |

| 1291 | |
| 1292 /* Allocating excessively large blocks on the stack can cause crashes. | |
| 851 | 1293 We provide MALLOC_OR_ALLOCA() below for places where it's likely that |
| 1294 large amounts will be allocated; it mallocs the block if it's too big. | |
| 1295 Unfortunately, that requires a call to unbind_to() at the end of the | |
| 1296 function, and it's not feasible to rewrite all calls to alloca() this | |
| 1297 way. | |
| 1298 | |
| 1299 Instead, we use the portable C alloca() substitute in alloca.c above a | |
| 1300 certain size. This actually uses malloc(), but checks the current stack | |
| 1301 pointer to see if data from previous alloca() calls needs to be freed. | |
| 1302 However, this can lead to large heap sizes -- especially since cleanup | |
| 1303 can only happen in a parent function, and will never happen if (as will | |
| 1304 often be the case) it's the same function in the same place in the code | |
| 1305 that keeps tripping the alloca() limit. | |
| 1306 | |
| 1307 So we set up a system to periodically force cleanup. Currently we | |
| 1308 do cleanup: | |
| 1309 | |
| 1310 -- Only when there's C alloca() data, and then | |
| 1311 -- Every stack alloca() or allocation of Lisp data, every call to | |
| 1312 next_event_internal() [typically near the top of the stack], | |
| 1313 or every 10th funcall | |
| 1314 | |
| 1315 This should not be a big penalty because | |
| 1316 | |
| 1317 (a) If there are few C alloca() chunks, checking them will be fast | |
| 1318 (b) If not, we've allocated a huge amount of heap space (remember, each | |
| 1319 chunk represents > 256K of heap), and we really want them gone | |
| 1320 */ | |
| 1321 | |
| 1322 /* We use a larger maximum when the choice is alloca() vs. the C alloca() | |
| 1323 substitute than when the choice is vs. malloc(), because in the former | |
| 1324 case, our alternative choice is less palatable because the memory may | |
| 1325 not be freed for awhile. */ | |

| 1768 | |
| 5038 | 1769 /* Dynarr locking and verification. |
| 1770 | |
| 1771 [I] VERIFICATION | |
| 1772 | |
| 1773 Verification routines simply return their basic argument, possibly | |
| 1774 casted, but in the process perform some verification on it, aborting if | |
| 1775 the verification fails. The verification routines take FILE and LINE | |
| 1776 parameters, and use them to output the file and line of the caller | |
| 1777 when an abort occurs, rather than the file and line of the inline | |
| 1778 function, which is less than useful. | |
| 1779 | |
| 1780 There are three basic types of verification routines: | |
| 1781 | |
| 1782 (1) Verify the dynarr itself. This verifies the basic invariant | |
| 1783 involving the length/size values: | |
| 1784 | |
| 1785 0 <= Dynarr_length(d) <= Dynarr_largest(d) <= Dynarr_max(d) | |
| 1786 | |
| 1787 (2) Verify the dynarr itself prior to modifying it. This performs | |
| 1788 the same verification as previously, but also checks that the | |
| 1789 dynarr is not locked (see below). | |
| 1790 | |
| 1791 (3) Verify a dynarr position. Unfortunately we have to have | |
| 1792 different verification routines depending on which kind of operation | |
| 1793 is being performed: | |
| 1794 | |
| 1795 (a) For Dynarr_at(), we check that the POS is bounded by Dynarr_largest(), | |
| 1796 i.e. 0 <= POS < Dynarr_largest(). | |
| 1797 (b) For Dynarr_atp_allow_end(), we also have to allow | |
| 1798 POS == Dynarr_largest(). | |
| 1799 (c) For Dynarr_atp(), we behave largely like Dynarr_at() but make a | |
| 1800 special exception when POS == 0 and Dynarr_largest() == 0 -- see | |
| 1801 comment below. | |
| 1802 (d) Some other routines contain the POS verification within their code, | |
| 1803 and make the check 0 <= POS < Dynarr_length() or | |
| 1804 0 <= POS <= Dynarr_length(). | |
| 1805 | |
| 1806 #### It is not well worked-out whether and in what circumstances it's | |
| 1807 allowed to use a position that is between Dynarr_length() and | |
| 1808 Dynarr_largest(). The ideal solution is to never allow this, and require | |
| 1809 instead that code first change the length before accessing higher | |
| 1810 positions. That would require looking through all the code that accesses | |
| 1811 dynarrs and fixing it appropriately (especially redisplay code, and | |
| 1812 especially redisplay code in the vicinity of a reference to | |
| 1813 Dynarr_largest(), since such code usually checks explicitly to see whether | |
| 1814 there is extra stuff between Dynarr_length() and Dynarr_largest().) | |
| 1815 | |
| 1816 [II] LOCKING | |
| 1817 | |
| 1818 The idea behind dynarr locking is simple: Locking a dynarr prevents | |
| 1819 any modification from occurring, or rather, leads to an abort upon | |
| 1820 any attempt to modify a dynarr. | |
| 1821 | |
| 1822 Dynarr locking was originally added to catch some sporadic and hard-to- | |
| 1823 debug crashes in the redisplay code where dynarrs appeared to be getting | |
| 1824 corrupted in an unexpected fashion. The solution was to lock the | |
| 1825 dynarrs that were getting corrupted (in this case, the display-line | |
| 1826 dynarrs) around calls to routines that weren't supposed to be changing | |
| 1827 these dynarrs but might somehow be calling code that modified them. | |
| 1828 This eventually revealed that there was a reentrancy problem with | |
| 1829 redisplay that involved the QUIT mechanism and the processing done in | |
| 1830 order to determine whether C-g had been pressed -- this processing | |
| 1831 involves retrieving, processing and queueing pending events to see | |
| 1832 whether any of them result in a C-g keypress. However, at least under | |
| 1833 MS Windows this can result in redisplay being called reentrantly. | |

| 442 | 2522 /*---------------------- list traversal macros -------------------------*/ |
| 2523 | |
| 2524 /* Note: These macros are for traversing through a list in some format, | |
| 2525 and executing code that you specify on each member of the list. | |
| 2526 | |
| 2527 There are two kinds of macros, those requiring surrounding braces, and | |
| 2528 those not requiring this. Which type of macro will be indicated. | |
| 2529 The general format for using a brace-requiring macro is | |
| 2530 | |
| 2531 { | |
| 2532 LIST_LOOP_3 (elt, list, tail) | |
| 2533 execute_code_here; | |
| 2534 } | |
| 2535 | |
| 2536 or | |
| 2537 | |
| 2538 { | |
| 2539 LIST_LOOP_3 (elt, list, tail) | |
| 2540 { | |
| 2541 execute_code_here; | |
| 2542 } | |
| 2543 } | |
| 2544 | |
| 2545 You can put variable declarations between the brace and beginning of | |
| 2546 macro, but NOTHING ELSE. | |
| 2547 | |
| 2548 The brace-requiring macros typically declare themselves any arguments | |
| 2549 that are initialized and iterated by the macros. If for some reason | |
| 2550 you need to declare these arguments yourself (e.g. to do something on | |
| 2551 them before the iteration starts, use the _NO_DECLARE versions of the | |
| 2552 macros.) | |
| 2553 */ | |
| 2554 | |
| 2555 /* There are two basic kinds of macros: those that handle "internal" lists | |
| 2556 that are known to be correctly structured (i.e. first element is a cons | |
| 2557 or nil, and the car of each cons is also a cons or nil, and there are | |
| 2558 no circularities), and those that handle "external" lists, where the | |
| 2559 list may have any sort of invalid formation. This is reflected in | |
| 2560 the names: those with "EXTERNAL_" work with external lists, and those | |
| 2561 without this prefix work with internal lists. The internal-list | |
| 2562 macros will hit an assertion failure if the structure is ill-formed; | |
| 2563 the external-list macros will signal an error in this case, either a | |
| 2564 malformed-list error or a circular-list error. | |
| 2565 */ | |
| 2566 | |
| 2367 | 2567 /* LIST_LOOP is a simple, old-fashioned macro. It doesn't require brace |
| 2568 surrounding, and iterates through a list, which may or may not known to | |
| 2569 be syntactically correct. It accepts two args, TAIL (set progressively | |
| 2570 to each cons starting with the first), and LIST, the list to iterate | |
| 2571 over. TAIL needs to be defined by the caller. | |
| 442 | 2572 |
| 2573 In each iteration, you can retrieve the current list item using XCAR | |

| 2586 LIST_LOOP_2 and EXTERNAL_LIST_LOOP_2 are the standard, most-often used | |
| 2587 macros. They take two arguments, an element variable ELT and the list | |
| 2588 LIST. ELT is automatically declared, and set to each element in turn | |
| 2589 from LIST. | |
| 2590 | |
| 2591 LIST_LOOP_3 and EXTERNAL_LIST_LOOP_3 are the same, but they have a third | |
| 2592 argument TAIL, another automatically-declared variable. At each iteration, | |
| 2593 this one points to the cons cell for which ELT is the car. | |
| 2594 | |
| 2595 EXTERNAL_LIST_LOOP_4 is like EXTERNAL_LIST_LOOP_3 but takes an additional | |
| 2596 LEN argument, again automatically declared, which counts the number of | |
| 2597 iterations gone by. It is 0 during the first iteration. | |

| 4422 The C++ code below catches GCPRO without UNGCPRO or vice-versa. | |
| 4423 Catching cases where there's no GCPRO or UNGCPRO but should be, however, | |
| 4424 is much harder, but could be done: | |
| 4425 | |
| 4426 1. Lisp_Object becomes a real object. Its creator and destructor need to | |
| 4427 figure out whether the object is on the stack (by looking at the range | |
| 4428 that `this' is within), and if so, add the pointer to a list of all | |
| 4429 stack-based Lisp_Objects. | |
| 4430 | |
| 4431 2. The assignment method needs to do reference-counting on actual Lisp | |
| 4432 objects -- in particular, we need to know if there are any references | |
| 4433 to a Lisp object that are *NOT* from stack-based Lisp_Objects. | |
| 4434 | |
| 4435 3. When we get to a point in the code where we might garbage collect -- | |
| 4436 i.e. Ffuncall(), Feval(), or Fgarbage_collect() is called -- we look | |
| 4437 at our list of stack-based Lisp_Objects, and if there are any that | |
| 4438 point to Lisp objects with no non-stack references, see if there are | |
| 4439 any gcpros pointing to the object, and if not, set a flag indicating | |
| 4440 that the object is "destroyed". (Don't abort yet because the function | |
| 4441 might not use the object any more.) | |
| 4442 | |
| 4443 4. When we detag a pointer using XFOO(), abort if its "destroyed" flag | |
