Overall point of this change and previous ones in this repository:
(1) Introduce new, clearer terminology: everything other than int
or char is a "record" object, which comes in two types: "normal
objects" and "frob-block objects". Fix up all places that
referred to frob-block objects as "simple", "basic", etc.
(2) Provide an advertised interface for doing operations on Lisp
objects, including creating new types, that is clean and
consistent in its naming, uses the above-referenced terms and
avoids referencing "lrecords", "old lcrecords", etc., which should
hide under the surface.
(3) Make the size_in_bytes and finalizer methods take a
Lisp_Object rather than a void * for consistency with other methods.
(4) Separate finalizer method into finalizer and disksaver, so
that normal finalize methods don't have to worry about disksaving.
Other specifics:
(1) Renaming:
LISP_OBJECT_HEADER -> NORMAL_LISP_OBJECT_HEADER
ALLOC_LISP_OBJECT -> ALLOC_NORMAL_LISP_OBJECT
implementation->basic_p -> implementation->frob_block_p
ALLOCATE_FIXED_TYPE_AND_SET_IMPL -> ALLOC_FROB_BLOCK_LISP_OBJECT
*FCCONFIG*, wrap_fcconfig -> *FC_CONFIG*, wrap_fc_config
*FCPATTERN*, wrap_fcpattern -> *FC_PATTERN*, wrap_fc_pattern
(the last two changes make the naming of these macros consistent
with the naming of all other macros, since the objects are named
fc-config and fc-pattern with a hyphen)
(2) Lots of documentation fixes in lrecord.h.
(3) Eliminate macros for copying, freeing, zeroing objects, getting
their storage size. Instead, new functions:
zero_sized_lisp_object()
zero_nonsized_lisp_object()
lisp_object_storage_size()
free_normal_lisp_object()
(copy_lisp_object() already exists)
LISP_OBJECT_FROB_BLOCK_P() (actually a macro)
Eliminated:
free_lrecord()
zero_lrecord()
copy_lrecord()
copy_sized_lrecord()
old_copy_lcrecord()
old_copy_sized_lcrecord()
old_zero_lcrecord()
old_zero_sized_lcrecord()
LISP_OBJECT_STORAGE_SIZE()
COPY_SIZED_LISP_OBJECT()
COPY_SIZED_LCRECORD()
COPY_LISP_OBJECT()
ZERO_LISP_OBJECT()
FREE_LISP_OBJECT()
(4) Catch the remaining places where lrecord stuff was used directly
and use the advertised interface, e.g. alloc_sized_lrecord() ->
ALLOC_SIZED_LISP_OBJECT().
(5) Make certain statically-declared pseudo-objects
(buffer_local_flags, console_local_flags) have their lheader
initialized correctly, so things like copy_lisp_object() can work
on them. Make extent_auxiliary_defaults a proper heap object
Vextent_auxiliary_defaults, and make extent auxiliaries dumpable
so that this object can be dumped. allocate_extent_auxiliary()
now just creates the object, and attach_extent_auxiliary()
creates an extent auxiliary and attaches to an extent, like the
old allocate_extent_auxiliary().
(6) Create EXTENT_AUXILIARY_SLOTS macro, similar to the foo-slots.h
files but in a macro instead of a file. The purpose is to avoid
duplication when iterating over all the slots in an extent auxiliary.
Use it.
(7) In lstream.c, don't zero out object after allocation because
allocation routines take care of this.
(8) In marker.c, fix a mistake in computing marker overhead.
(9) In print.c, clean up printing_unreadable_lcrecord(),
external_object_printer() to avoid lots of ifdef NEW_GC's.
(10) Separate toolbar-button allocation into a separate
allocate_toolbar_button() function for use in the example code
in lrecord.h.

| 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 | |

| 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. | |

| 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). | |

| 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 | |

| 1777 /************* Dynarr verification *************/ | |
| 1778 | |
| 5038 | 1779 /* Dynarr locking and verification. |
| 1780 | |
| 1781 [I] VERIFICATION | |
| 1782 | |
| 1783 Verification routines simply return their basic argument, possibly | |
| 1784 casted, but in the process perform some verification on it, aborting if | |
| 1785 the verification fails. The verification routines take FILE and LINE | |
| 1786 parameters, and use them to output the file and line of the caller | |
| 1787 when an abort occurs, rather than the file and line of the inline | |
| 1788 function, which is less than useful. | |
| 1789 | |
| 1790 There are three basic types of verification routines: | |
| 1791 | |
| 1792 (1) Verify the dynarr itself. This verifies the basic invariant | |
| 1793 involving the length/size values: | |
| 1794 | |
| 1795 0 <= Dynarr_length(d) <= Dynarr_largest(d) <= Dynarr_max(d) | |
| 1796 | |
| 1797 (2) Verify the dynarr itself prior to modifying it. This performs | |
| 1798 the same verification as previously, but also checks that the | |
| 1799 dynarr is not locked (see below). | |
| 1800 | |
| 1801 (3) Verify a dynarr position. Unfortunately we have to have | |
| 1802 different verification routines depending on which kind of operation | |
| 1803 is being performed: | |
| 1804 | |
| 1805 (a) For Dynarr_at(), we check that the POS is bounded by Dynarr_largest(), | |
| 1806 i.e. 0 <= POS < Dynarr_largest(). | |
| 1807 (b) For Dynarr_atp_allow_end(), we also have to allow | |
| 1808 POS == Dynarr_largest(). | |
| 1809 (c) For Dynarr_atp(), we behave largely like Dynarr_at() but make a | |
| 1810 special exception when POS == 0 and Dynarr_largest() == 0 -- see | |
| 1811 comment below. | |
| 1812 (d) Some other routines contain the POS verification within their code, | |
| 1813 and make the check 0 <= POS < Dynarr_length() or | |
| 1814 0 <= POS <= Dynarr_length(). | |
| 1815 | |
| 1816 #### It is not well worked-out whether and in what circumstances it's | |
| 1817 allowed to use a position that is between Dynarr_length() and | |
| 1818 Dynarr_largest(). The ideal solution is to never allow this, and require | |
| 1819 instead that code first change the length before accessing higher | |
| 1820 positions. That would require looking through all the code that accesses | |
| 1821 dynarrs and fixing it appropriately (especially redisplay code, and | |
| 1822 especially redisplay code in the vicinity of a reference to | |
| 1823 Dynarr_largest(), since such code usually checks explicitly to see whether | |
| 1824 there is extra stuff between Dynarr_length() and Dynarr_largest().) | |
| 1825 | |
| 1826 [II] LOCKING | |
| 1827 | |
| 1828 The idea behind dynarr locking is simple: Locking a dynarr prevents | |
| 1829 any modification from occurring, or rather, leads to an abort upon | |
| 1830 any attempt to modify a dynarr. | |
| 1831 | |
| 1832 Dynarr locking was originally added to catch some sporadic and hard-to- | |
| 1833 debug crashes in the redisplay code where dynarrs appeared to be getting | |
| 1834 corrupted in an unexpected fashion. The solution was to lock the | |
| 1835 dynarrs that were getting corrupted (in this case, the display-line | |
| 1836 dynarrs) around calls to routines that weren't supposed to be changing | |
| 1837 these dynarrs but might somehow be calling code that modified them. | |
| 1838 This eventually revealed that there was a reentrancy problem with | |
| 1839 redisplay that involved the QUIT mechanism and the processing done in | |
| 1840 order to determine whether C-g had been pressed -- this processing | |
| 1841 involves retrieving, processing and queueing pending events to see | |
| 1842 whether any of them result in a C-g keypress. However, at least under | |
| 1843 MS Windows this can result in redisplay being called reentrantly. | |

| 442 | 2532 /*---------------------- list traversal macros -------------------------*/ |
| 2533 | |
| 2534 /* Note: These macros are for traversing through a list in some format, | |
| 2535 and executing code that you specify on each member of the list. | |
| 2536 | |
| 2537 There are two kinds of macros, those requiring surrounding braces, and | |
| 2538 those not requiring this. Which type of macro will be indicated. | |
| 2539 The general format for using a brace-requiring macro is | |
| 2540 | |
| 2541 { | |
| 2542 LIST_LOOP_3 (elt, list, tail) | |
| 2543 execute_code_here; | |
| 2544 } | |
| 2545 | |
| 2546 or | |
| 2547 | |
| 2548 { | |
| 2549 LIST_LOOP_3 (elt, list, tail) | |
| 2550 { | |
| 2551 execute_code_here; | |
| 2552 } | |
| 2553 } | |
| 2554 | |
| 2555 You can put variable declarations between the brace and beginning of | |
| 2556 macro, but NOTHING ELSE. | |
| 2557 | |
| 2558 The brace-requiring macros typically declare themselves any arguments | |
| 2559 that are initialized and iterated by the macros. If for some reason | |
| 2560 you need to declare these arguments yourself (e.g. to do something on | |
| 2561 them before the iteration starts, use the _NO_DECLARE versions of the | |
| 2562 macros.) | |
| 2563 */ | |
| 2564 | |
| 2565 /* There are two basic kinds of macros: those that handle "internal" lists | |
| 2566 that are known to be correctly structured (i.e. first element is a cons | |
| 2567 or nil, and the car of each cons is also a cons or nil, and there are | |
| 2568 no circularities), and those that handle "external" lists, where the | |
| 2569 list may have any sort of invalid formation. This is reflected in | |
| 2570 the names: those with "EXTERNAL_" work with external lists, and those | |
| 2571 without this prefix work with internal lists. The internal-list | |
| 2572 macros will hit an assertion failure if the structure is ill-formed; | |
| 2573 the external-list macros will signal an error in this case, either a | |
| 2574 malformed-list error or a circular-list error. | |
| 2575 */ | |
| 2576 | |
| 2367 | 2577 /* LIST_LOOP is a simple, old-fashioned macro. It doesn't require brace |
| 2578 surrounding, and iterates through a list, which may or may not known to | |
| 2579 be syntactically correct. It accepts two args, TAIL (set progressively | |
| 2580 to each cons starting with the first), and LIST, the list to iterate | |
| 2581 over. TAIL needs to be defined by the caller. | |
| 442 | 2582 |
| 2583 In each iteration, you can retrieve the current list item using XCAR | |
| 2584 (tail), or destructively modify the list using XSETCAR (tail, | |
| 2585 ...). */ | |

| 2595 | |
| 2596 LIST_LOOP_2 and EXTERNAL_LIST_LOOP_2 are the standard, most-often used | |
| 2597 macros. They take two arguments, an element variable ELT and the list | |
| 2598 LIST. ELT is automatically declared, and set to each element in turn | |
| 2599 from LIST. | |
| 2600 | |
| 2601 LIST_LOOP_3 and EXTERNAL_LIST_LOOP_3 are the same, but they have a third | |
| 2602 argument TAIL, another automatically-declared variable. At each iteration, | |
| 2603 this one points to the cons cell for which ELT is the car. | |
| 2604 | |
| 2605 EXTERNAL_LIST_LOOP_4 is like EXTERNAL_LIST_LOOP_3 but takes an additional | |
| 2606 LEN argument, again automatically declared, which counts the number of | |
| 2607 iterations gone by. It is 0 during the first iteration. | |
| 2608 | |
| 2609 EXTERNAL_LIST_LOOP_4_NO_DECLARE is like EXTERNAL_LIST_LOOP_4 but none | |
| 2610 of the variables are automatically declared, and so you need to declare | |
| 2611 them yourself. (ELT and TAIL are Lisp_Objects, and LEN is an EMACS_INT.) | |

| 4301 | |
| 4302 The C++ code below catches GCPRO without UNGCPRO or vice-versa. | |
| 4303 Catching cases where there's no GCPRO or UNGCPRO but should be, however, | |
| 4304 is much harder, but could be done: | |
| 4305 | |
| 4306 1. Lisp_Object becomes a real object. Its creator and destructor need to | |
| 4307 figure out whether the object is on the stack (by looking at the range | |
| 4308 that `this' is within), and if so, add the pointer to a list of all | |
| 4309 stack-based Lisp_Objects. | |
| 4310 | |
| 4311 2. The assignment method needs to do reference-counting on actual Lisp | |
| 4312 objects -- in particular, we need to know if there are any references | |
| 4313 to a Lisp object that are *NOT* from stack-based Lisp_Objects. | |
| 4314 | |
| 4315 3. When we get to a point in the code where we might garbage collect -- | |
| 4316 i.e. Ffuncall(), Feval(), or Fgarbage_collect() is called -- we look | |
| 4317 at our list of stack-based Lisp_Objects, and if there are any that | |
| 4318 point to Lisp objects with no non-stack references, see if there are | |
| 4319 any gcpros pointing to the object, and if not, set a flag indicating | |
| 4320 that the object is "destroyed". (Don't abort yet because the function | |
| 4321 might not use the object any more.) | |
| 4322 | |
| 4323 4. When we detag a pointer using XFOO(), abort if its "destroyed" flag | |
| 4324 is set. | |
