annotate src/faces.c @ 4843:715b15990d0a
add more foo_checking_assert macros
lisp.h: Add structure_checking_assert(), gc_checking_assert(), etc. for
all types of error-checking. Also FOO_checking_assert_with_message()
and inline_FOO_checking_assert() -- the latter for use in an inline
function where you want the calling function's line/file to be reported
(requires some conspiracy with the function itself).
Add disabled_assert(), disabled_assert_at_line(),
disabled_assert_with_message(), for what to do when an assert is
disabled. Formerly, we used to do ((void) 0), but now we do
((void) x), so the variable appears used and any side effects of the
expression do get done. In Unicode-internal, the standard assert()
uses this, but not yet in this workspace.

| 982 #### Here is a description of how the face cache elements ought | |
| 983 to be redone. It is *NOT* how they work currently: | |
| 984 | |
| 985 However, when I started to go about implementing this, I realized | |
| 986 that there are all sorts of subtle problems with cache coherency | |
| 987 that are coming up. As it turns out, these problems don't | |
| 988 manifest themselves now due to the brute-force "kill 'em all" | |
| 989 approach to cache invalidation when faces change; but if this | |
| 990 is ever made smarter, these problems are going to come up, and | |
| 991 some of them are very non-obvious. | |
| 992 | |
| 993 I'm thinking of redoing the cache code a bit to avoid these | |
| 994 coherency problems. The bulk of the problems will arise because | |
| 995 the current display structures have simple indices into the | |
| 996 face cache, but the cache can be changed at various times, | |
| 997 which could make the current display structures incorrect. | |
| 998 I guess the dirty and updated flags are an attempt to fix | |
| 999 this, but this approach doesn't really work. | |
| 1000 | |
| 1001 Here's an approach that should keep things clean and unconfused: | |
| 1002 | |
| 1003 1) Imagine a "virtual face cache" that can grow arbitrarily | |
| 1004 big and for which the only thing allowed is to add new | |
| 1005 elements. Existing elements cannot be removed or changed. | |
| 1006 This way, any pointers in the existing redisplay structure | |
| 1007 into the cache never get screwed up. (This is important | |
| 1008 because even if a cache element is out of date, if there's | |
| 1009 a pointer to it then its contents still accurately describe | |
| 1010 the way the text currently looks on the screen.) | |
| 1011 2) Each element in the virtual cache either describes exactly | |
| 1012 one face, or describes the merger of a number of faces | |
| 1013 by some process. In order to simplify things, for mergers | |
| 1014 we do not record which faces or ordering was used, but | |
| 1015 simply that this cache element is the result of merging. | |
| 1016 Unlike the current implementation, it's important that a | |
| 1017 single cache element not be used to both describe a | |
| 1018 single face and describe a merger, even if all the property | |
| 1019 values are the same. | |
| 1020 3) Each cache element can be clean or dirty. "Dirty" means | |
| 1021 that the face that the element points to has been changed; | |
| 1022 this gets set at the time the face is changed. This | |
| 1023 way, when looking up a value in the cache, you can determine | |
| 1024 whether it's out of date or not. For merged faces it | |
| 1025 does not matter -- we don't record the faces or priority | |
| 1026 used to create the merger, so it's impossible to look up | |
| 1027 one of these faces. We have to recompute it each time. | |
| 1028 Luckily, this is fine -- doing the merge is much | |
| 1029 less expensive than recomputing the properties of a | |
| 1030 single face. | |
| 1031 4) For each cache element, we keep a hash value. (In order | |
| 1032 to hash the boolean properties, we convert each of them | |
| 1033 into a different large prime number so that the hashing works | |
| 1034 well.) This allows us, when comparing runes, to properly | |
| 1035 determine whether the face for that rune has changed. | |
| 1036 This will be especially important for TTY's, where there | |
| 1037 aren't that many faces and minimizing redraw is very | |
| 1038 important. | |
| 1039 5) We can't actually keep an infinite cache, but that doesn't | |
| 1040 really matter that much. The only elements we care about | |
| 1041 are those that are used by either the current or desired | |
| 1042 display structs. Therefore, we keep a per-window | |
| 1043 redisplay iteration number, and mark each element with | |
| 1044 that number as we use it. Just after outputting the | |
| 1045 window and synching the redisplay structs, we go through | |
| 1046 the cache and invalidate all elements that are not clean | |
| 1047 elements referring to a particular face and that do not | |
| 1048 have an iteration number equal to the current one. We | |
| 1049 keep them in a chain, and use them to allocate new | |
| 1050 elements when possible instead of increasing the Dynarr. | |

1401 - a new window is created and its face cache elements are |
| 446 | 1402 initialized through a call to reset_face_cachels[1]. At that point, |
| 1403 the cache for the default and modeline faces (normaly taken care of | |
| 1404 by redisplay itself) are null. | |
| 1405 - the default face has a background pixmap which needs to be | |
| 1406 instantiated right here, as a consequence of cache initialization. | |
| 1407 - the background pixmap image happens to be instantiated as a string | |
| 1408 (this happens on tty's for instance). | |
| 1409 - In order to do this, we need to compute the string geometry. | |
| 1410 - In order to do this, we might have to access the window's default | |
| 1411 face cache. But this is the cache we're building right now, it is | |
| 1412 null. | |
| 1413 - BARF !!!!! | |
| 428 | 1414 |
| 446 | 1415 To sum up, this means that it is in general unsafe to instantiate |
| 1416 images before face cache updating is complete (appart from image | |
| 1417 related face attributes). The solution we use below is to actually | |
| 1418 detect whether we're building the window's face_cachels for the first | |
| 1419 time, and simply NOT frob the background pixmap in that case. If | |
| 1420 other image-related face attributes are ever implemented, they should | |
| 1421 be protected the same way right here. | |
| 1422 | |
| 1423 One note: | |
