981 | |
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1008 because even if a cache element is out of date, if there's | |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: | |
1424 * See comment in `default_face_font_info' in face.c. Who wrote it ? | |
1425 Maybe we have the begining of an answer here ? | |

1951 * face table every time it is called, it gets terribly slow when | |
1952 * there are many faces. Creating 500 faces on a 50Mhz 486 took | |
