| 983 #### Here is a description of how the face cache elements ought | |
| 984 to be redone. It is *NOT* how they work currently: | |
| 985 | |
| 986 However, when I started to go about implementing this, I realized | |
| 987 that there are all sorts of subtle problems with cache coherency | |
| 988 that are coming up. As it turns out, these problems don't | |
| 989 manifest themselves now due to the brute-force "kill 'em all" | |
| 990 approach to cache invalidation when faces change; but if this | |
| 991 is ever made smarter, these problems are going to come up, and | |
| 992 some of them are very non-obvious. | |
| 993 | |
| 994 I'm thinking of redoing the cache code a bit to avoid these | |
| 995 coherency problems. The bulk of the problems will arise because | |
| 996 the current display structures have simple indices into the | |
| 997 face cache, but the cache can be changed at various times, | |
| 998 which could make the current display structures incorrect. | |
| 999 I guess the dirty and updated flags are an attempt to fix | |
| 1000 this, but this approach doesn't really work. | |
| 1001 | |
| 1002 Here's an approach that should keep things clean and unconfused: | |
| 1003 | |
| 1004 1) Imagine a "virtual face cache" that can grow arbitrarily | |
| 1005 big and for which the only thing allowed is to add new | |
| 1006 elements. Existing elements cannot be removed or changed. | |
| 1007 This way, any pointers in the existing redisplay structure | |
| 1008 into the cache never get screwed up. (This is important | |
| 1009 because even if a cache element is out of date, if there's | |
| 1010 a pointer to it then its contents still accurately describe | |
| 1011 the way the text currently looks on the screen.) | |
| 1012 2) Each element in the virtual cache either describes exactly | |
| 1013 one face, or describes the merger of a number of faces | |
| 1014 by some process. In order to simplify things, for mergers | |
| 1015 we do not record which faces or ordering was used, but | |
| 1016 simply that this cache element is the result of merging. | |
| 1017 Unlike the current implementation, it's important that a | |
| 1018 single cache element not be used to both describe a | |
| 1019 single face and describe a merger, even if all the property | |
| 1020 values are the same. | |
| 1021 3) Each cache element can be clean or dirty. "Dirty" means | |
| 1022 that the face that the element points to has been changed; | |
| 1023 this gets set at the time the face is changed. This | |
| 1024 way, when looking up a value in the cache, you can determine | |
| 1025 whether it's out of date or not. For merged faces it | |
| 1026 does not matter -- we don't record the faces or priority | |
| 1027 used to create the merger, so it's impossible to look up | |
| 1028 one of these faces. We have to recompute it each time. | |
| 1029 Luckily, this is fine -- doing the merge is much | |
| 1030 less expensive than recomputing the properties of a | |
| 1031 single face. | |
| 1032 4) For each cache element, we keep a hash value. (In order | |
| 1033 to hash the boolean properties, we convert each of them | |
| 1034 into a different large prime number so that the hashing works | |
| 1035 well.) This allows us, when comparing runes, to properly | |
| 1036 determine whether the face for that rune has changed. | |
| 1037 This will be especially important for TTY's, where there | |
| 1038 aren't that many faces and minimizing redraw is very | |
| 1039 important. | |
| 1040 5) We can't actually keep an infinite cache, but that doesn't | |
| 1041 really matter that much. The only elements we care about | |
| 1042 are those that are used by either the current or desired | |
| 1043 display structs. Therefore, we keep a per-window | |
| 1044 redisplay iteration number, and mark each element with | |
| 1045 that number as we use it. Just after outputting the | |
| 1046 window and synching the redisplay structs, we go through | |
| 1047 the cache and invalidate all elements that are not clean | |
| 1048 elements referring to a particular face and that do not | |
| 1049 have an iteration number equal to the current one. We | |
| 1050 keep them in a chain, and use them to allocate new | |
| 1051 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. | |
