| 988 #### Here is a description of how the face cache elements ought | |
| 989 to be redone. It is *NOT* how they work currently: | |
| 990 | |
| 991 However, when I started to go about implementing this, I realized | |
| 992 that there are all sorts of subtle problems with cache coherency | |
| 993 that are coming up. As it turns out, these problems don't | |
| 994 manifest themselves now due to the brute-force "kill 'em all" | |
| 995 approach to cache invalidation when faces change; but if this | |
| 996 is ever made smarter, these problems are going to come up, and | |
| 997 some of them are very non-obvious. | |
| 998 | |
| 999 I'm thinking of redoing the cache code a bit to avoid these | |
| 1000 coherency problems. The bulk of the problems will arise because | |
| 1001 the current display structures have simple indices into the | |
| 1002 face cache, but the cache can be changed at various times, | |
| 1003 which could make the current display structures incorrect. | |
| 1004 I guess the dirty and updated flags are an attempt to fix | |
| 1005 this, but this approach doesn't really work. | |
| 1006 | |
| 1007 Here's an approach that should keep things clean and unconfused: | |
| 1008 | |
| 1009 1) Imagine a "virtual face cache" that can grow arbitrarily | |
| 1010 big and for which the only thing allowed is to add new | |
| 1011 elements. Existing elements cannot be removed or changed. | |
| 1012 This way, any pointers in the existing redisplay structure | |
| 1013 into the cache never get screwed up. (This is important | |
| 1014 because even if a cache element is out of date, if there's | |
| 1015 a pointer to it then its contents still accurately describe | |
| 1016 the way the text currently looks on the screen.) | |
| 1017 2) Each element in the virtual cache either describes exactly | |
| 1018 one face, or describes the merger of a number of faces | |
| 1019 by some process. In order to simplify things, for mergers | |
| 1020 we do not record which faces or ordering was used, but | |
| 1021 simply that this cache element is the result of merging. | |
| 1022 Unlike the current implementation, it's important that a | |
| 1023 single cache element not be used to both describe a | |
| 1024 single face and describe a merger, even if all the property | |
| 1025 values are the same. | |
| 1026 3) Each cache element can be clean or dirty. "Dirty" means | |
| 1027 that the face that the element points to has been changed; | |
| 1028 this gets set at the time the face is changed. This | |
| 1029 way, when looking up a value in the cache, you can determine | |
| 1030 whether it's out of date or not. For merged faces it | |
| 1031 does not matter -- we don't record the faces or priority | |
| 1032 used to create the merger, so it's impossible to look up | |
| 1033 one of these faces. We have to recompute it each time. | |
| 1034 Luckily, this is fine -- doing the merge is much | |
| 1035 less expensive than recomputing the properties of a | |
| 1036 single face. | |
| 1037 4) For each cache element, we keep a hash value. (In order | |
| 1038 to hash the boolean properties, we convert each of them | |
| 1039 into a different large prime number so that the hashing works | |
| 1040 well.) This allows us, when comparing runes, to properly | |
| 1041 determine whether the face for that rune has changed. | |
| 1042 This will be especially important for TTY's, where there | |
| 1043 aren't that many faces and minimizing redraw is very | |
| 1044 important. | |
| 1045 5) We can't actually keep an infinite cache, but that doesn't | |
| 1046 really matter that much. The only elements we care about | |
| 1047 are those that are used by either the current or desired | |
| 1048 display structs. Therefore, we keep a per-window | |
| 1049 redisplay iteration number, and mark each element with | |
| 1050 that number as we use it. Just after outputting the | |
| 1051 window and synching the redisplay structs, we go through | |
| 1052 the cache and invalidate all elements that are not clean | |
| 1053 elements referring to a particular face and that do not | |
| 1054 have an iteration number equal to the current one. We | |
| 1055 keep them in a chain, and use them to allocate new | |
| 1056 elements when possible instead of increasing the Dynarr. | |

1406 - a new window is created and its face cache elements are |
| 446 | 1407 initialized through a call to reset_face_cachels[1]. At that point, |
| 1408 the cache for the default and modeline faces (normaly taken care of | |
| 1409 by redisplay itself) are null. | |
| 1410 - the default face has a background pixmap which needs to be | |
| 1411 instantiated right here, as a consequence of cache initialization. | |
| 1412 - the background pixmap image happens to be instantiated as a string | |
| 1413 (this happens on tty's for instance). | |
| 1414 - In order to do this, we need to compute the string geometry. | |
| 1415 - In order to do this, we might have to access the window's default | |
| 1416 face cache. But this is the cache we're building right now, it is | |
| 1417 null. | |
| 1418 - BARF !!!!! | |
| 428 | 1419 |
| 446 | 1420 To sum up, this means that it is in general unsafe to instantiate |
| 1421 images before face cache updating is complete (appart from image | |
| 1422 related face attributes). The solution we use below is to actually | |
| 1423 detect whether we're building the window's face_cachels for the first | |
| 1424 time, and simply NOT frob the background pixmap in that case. If | |
| 1425 other image-related face attributes are ever implemented, they should | |
| 1426 be protected the same way right here. | |
