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 (???).

1104
|
|
|
1105 Allocating excessively large blocks on the stack can cause crashes.
|
|
|
1106 We provide MALLOC_OR_ALLOCA() below for places where it's likely that
|
|
|
1107 large amounts will be allocated; it mallocs the block if it's too big.
|
|
|
1108 Unfortunately, that requires a call to unbind_to() at the end of the
|
|
|
1109 function, and it's not feasible to rewrite all calls to alloca() this
|
|
|
1110 way.
|
|
|
1111
|
|
|
1112 Instead, we use the portable C alloca() substitute in alloca.c above a
|
|
|
1113 certain size. This actually uses malloc(), but checks the current stack
|
|
|
1114 pointer to see if data from previous alloca() calls needs to be freed.
|
|
|
1115 However, this can lead to large heap sizes -- especially since cleanup
|
|
|
1116 can only happen in a parent function, and will never happen if (as will
|
|
|
1117 often be the case) it's the same function in the same place in the code
|
|
|
1118 that keeps tripping the alloca() limit.
|
|
|
1119
|
|
|
1120 So we set up a system to periodically force cleanup. Currently we
|
|
|
1121 do cleanup:
|
|
|
1122
|
|
|
1123 -- Only when there's C alloca() data, and then
|
|
|
1124 -- Every stack alloca() or allocation of Lisp data, every call to
|
|
|
1125 next_event_internal() [typically near the top of the stack],
|
|
|
1126 or every 10th funcall
|
|
|
1127
|
|
|
1128 This should not be a big penalty because
|
|
|
1129
|
|
|
1130 (a) If there are few C alloca() chunks, checking them will be fast
|
|
|
1131 (b) If not, we've allocated a huge amount of heap space (remember, each
|
|
|
1132 chunk represents > 256K of heap), and we really want them gone
|
|
|
1133 */

1751 and executing code that you specify on each member of the list.
|

1752
|
|
|
1753 There are two kinds of macros, those requiring surrounding braces, and
|
|
|
1754 those not requiring this. Which type of macro will be indicated.
|
|
|
1755 The general format for using a brace-requiring macro is
|
|
|
1756
|
|
|
1757 {
|
|
|
1758 LIST_LOOP_3 (elt, list, tail)

|
|
|
1770
|
|
|
1771 You can put variable declarations between the brace and beginning of
|
|
|
1772 macro, but NOTHING ELSE.
|
|
|
1773
|
|
|
1774 The brace-requiring macros typically declare themselves any arguments
|
|
|
1775 that are initialized and iterated by the macros. If for some reason
|
|
|
1776 you need to declare these arguments yourself (e.g. to do something on
|
|
|
1777 them before the iteration starts, use the _NO_DECLARE versions of the
|
|
|
1778 macros.)
|
|
|
1779 */
|
|
|
1780
|
|
|
1781 /* There are two basic kinds of macros: those that handle "internal" lists
|
|
|
1782 that are known to be correctly structured (i.e. first element is a cons
|
|
|
1783 or nil, and the car of each cons is also a cons or nil, and there are
|
|
|
1784 no circularities), and those that handle "external" lists, where the
|
|
|
1785 list may have any sort of invalid formation. This is reflected in
|
|
|
1786 the names: those with "EXTERNAL_" work with external lists, and those
|
|
|
1787 without this prefix work with internal lists. The internal-list
|
|
|
1788 macros will hit an assertion failure if the structure is ill-formed;
|
|
|
1789 the external-list macros will signal an error in this case, either a
|
|
|
1790 malformed-list error or a circular-list error.
|
|
|
1791
|
|
|
1792 Note also that the simplest external list iterator, EXTERNAL_LIST_LOOP,
|
|
|
1793 does *NOT* check for circularities. Therefore, make sure you call
|
|
|
1794 QUIT each iteration or so. However, it's probably easier just to use
|
|
|
1795 EXTERNAL_LIST_LOOP_2, which is easier to use in any case.

1830 from LIST.

1833 argument TAIL, another automatically-declared variable. At each iteration,

1835

1836 EXTERNAL_LIST_LOOP_4 is like EXTERNAL_LIST_LOOP_3 but takes an additional

1837 LEN argument, again automatically declared, which counts the number of

1838 iterations gone by. It is 0 during the first iteration.

1839
|
|
|
1840 EXTERNAL_LIST_LOOP_4_NO_DECLARE is like EXTERNAL_LIST_LOOP_4 but none

|

1841 of the variables are automatically declared, and so you need to declare
|

1842 them yourself. (ELT and TAIL are Lisp_Objects, and LEN is an EMACS_INT.)

3062 /* When support for message translation exists, GETTEXT() translates a
|
|
|
3063 string from English into the language defined by
|
|
|
3064 `current-language-environment'. This is done by looking the string
|
|
|
3065 up in a large predefined table; if no translation is found, the
|
|
|
3066 original string is returned, and the failure is possibly logged so
|
|
|
3067 that the translation can later be entered into the table.
|
|
|
3068
|
|
|
3069 In addition to this, there is a mechanism to snarf message strings
|
|
|
3070 out of the source code so that they can be entered into the tables.
|
|
|
3071 This is what make-msgfile.lex does.
|
|
|
3072
|
|
|
3073 Handling `format' strings is more difficult: The format string
|
|
|
3074 should get translated, but not under all circumstances. When the
|
|
|
3075 format string is a Lisp string, what should happen is that
|
|
|
3076 Fformat() should format the untranslated args[0] and return that,
|
|
|
3077 and also call Fgettext() on args[0] and, if that is different,
|
|
|
3078 format it and store it in the `string-translatable' property of the
|
|
|
3079 returned string. See Fgettext().
|
|
|
3080
|
|
|
3081 CGETTEXT() is the same as GETTEXT() but works with char * strings
|
|
867
|
3082 instead of Ibyte * strings.

3084 build_msg_string() is a shorthand for build_string (GETTEXT (x)).

|

3121 Catching cases where there's no GCPRO or UNGCPRO but should be, however,
|
|
|
3122 is much harder, but could be done:
|
|
|
3123
|
|
|
3124 1. Lisp_Object becomes a real object. Its creator and destructor need to
|
|
|
3125 figure out whether the object is on the stack (by looking at the range
|
|
|
3126 that `this' is within), and if so, add the pointer to a list of all
|
|
|
3127 stack-based Lisp_Objects.
|
|
|
3128
|
|
|
3129 2. The assignment method needs to do reference-counting on actual Lisp
|
|
|
3130 objects -- in particular, we need to know if there are any references
|
|
|
3131 to a Lisp object that are *NOT* from stack-based Lisp_Objects.
|
|
|
3132
|
|
|
3133 3. When we get to a point in the code where we might garbage collect --
|
|
|
3134 i.e. Ffuncall(), Feval(), or Fgarbage_collect() is called -- we look
|
|
|
3135 at our list of stack-based Lisp_Objects, and if there are any that
|
|
|
3136 point to Lisp objects with no non-stack references, see if there are
|
|
|
3137 any gcpros pointing to the object, and if not, set a flag indicating
|
|
|
3138 that the object is "destroyed". (Don't abort yet because the function
|
|
|
3139 might not use the object any more.)
|
|
|
3140
|
|
|
3141 4. When we detag a pointer using XFOO(), abort if its "destroyed" flag
|
|
|
3142 is set.
