Redo the dynarr code, add greater checks.
Rename the `len', `largest' and `max' members to `len_',
`largest_' and `max_' to try and catch existing places that might
directly modify these values. Make new accessors Dynarr_largest()
and Dynarr_max() and make them and existing Dynarr_length() be
non-lvalues by adding '+ 0' to them; fix a couple of places in the
redisplay code that tried to modify the length directly by setting
Dynarr_length(). Use the accessors whenever possible even in the
dynarr code itself. The accessors also verify that 0 <= len <=
largest <= max. Rename settor function Dynarr_set_size() to
Dynarr_set_length() and use it more consistently; also create
lower-level Dynarr_set_length_1(). This latter function should be
the only function that directly modifies the `len_' member of a
Dynarr, and in the process makes sure that the `largest' value is
kept correct.
Consistently use ERROR_CHECK_STRUCTURES instead of
ERROR_CHECK_TYPES for error-checking code. Reintroduce the
temporarily disabled verification code on the positions of
Dynarr_at(), Dynarr_atp() and Dynarr_atp_past_end().
Also create Dynarr_resize_if() in place of a repeated
code fragment. Clean up all the functions that modify Dynarrs to
use the new macros and functions and verify the correctness of the
Dynarr both before and after the change.
Note that there are two kinds of verification -- one for accessing
and one for modifying. The difference is that the modify
verification additionally checks to make sure that the Dynarr
isn't locked. (This is used in redisplay to check for problems
with reentrancy.)
* lrecord.h: Move XD_DYNARR_DESC to lisp.h, grouping with the dynarr code.

| 24 ;;; Synched up with: FSF 19.30. (font-lock.el) | |
| 25 | |
| 26 ;;; Commentary: | |
| 27 | |
| 28 ;; The reason for the existence of this file is so that modes can | |
| 29 ;; call `font-lock-set-defaults' without worrying about whether | |
| 30 ;; font-lock is loaded. We don't autoload this from font-lock.el | |
| 31 ;; because loading font-lock.el automatically turns font-lock on. | |
| 32 | |
| 33 ;;; Code: | |
| 34 | |
| 35 (defun font-lock-set-defaults (&optional explicit-defaults) | |
| 36 "Set fontification defaults appropriately for this mode. | |
| 37 Sets `font-lock-keywords', `font-lock-keywords-only', `font-lock-syntax-table', | |
| 38 `font-lock-beginning-of-syntax-function' and | |
| 39 `font-lock-keywords-case-fold-search'. | |
| 40 | |
| 41 If `font-lock-defaults' is currently set, it is used. Otherwise, the | |
| 42 symbol naming the major mode is examined for a `font-lock-defaults' | |
| 43 property. If that is not present, but a variable `foo-mode-font-lock-keywords' | |
| 44 is, the value of that variable is used as the default for | |
| 45 `font-lock-keywords'. Various other backward-compatible behaviors also | |
| 46 exist -- if you're curious, look at the source. | |
| 47 | |
| 48 The value of `font-lock-maximum-decoration' is used to determine which | |
| 49 set of keywords applies, if more than one exists. | |
| 50 | |
| 51 This will also put the buffer into Font Lock mode if any keywords exist | |
| 52 and if auto-fontification is called for, as determined by | |
| 53 `font-lock-auto-fontify', `font-lock-mode-enable-list', and | |
| 54 `font-lock-mode-disable-list'. | |
| 55 | |
| 56 Calling this function multiple times in the same buffer is safe -- this | |
| 57 function keeps track of whether it has already been called in this | |
| 58 buffer, and does nothing if so. This allows for multiple ways of getting | |
| 59 Font Lock properly initialized in a buffer, to deal with existing major | |
| 60 modes that do not call this function. (For example, Font Lock adds this | |
| 61 function to `find-file-hooks'.) | |
| 62 | |
| 63 Major modes that have any font-lock defaults specified should call this | |
| 64 function during their initialization process, after they have set | |
| 65 the variable `major-mode'. | |
| 66 | |
| 67 If EXPLICIT-DEFAULTS is t, this function will not check whether it | |
| 68 has already been run in this buffer, and will always do the full | |
| 69 computation. | |
| 70 | |
| 71 If EXPLICIT-DEFAULTS is not nil and not t, it should be something | |
| 72 that is allowable as a value for `font-lock-defaults' and will be | |
| 73 used to initialize the Font Lock variables." | |
