956 #### Here is a description of how the face cache elements ought
|
|
|
957 to be redone. It is *NOT* how they work currently:
|
|
|
958
|
|
|
959 However, when I started to go about implementing this, I realized
|
|
|
960 that there are all sorts of subtle problems with cache coherency
|
|
|
961 that are coming up. As it turns out, these problems don't
|
|
|
962 manifest themselves now due to the brute-force "kill 'em all"
|
|
|
963 approach to cache invalidation when faces change; but if this
|
|
|
964 is ever made smarter, these problems are going to come up, and
|
|
|
965 some of them are very non-obvious.
|
|
|
966
|
|
|
967 I'm thinking of redoing the cache code a bit to avoid these
|
|
|
968 coherency problems. The bulk of the problems will arise because
|
|
|
969 the current display structures have simple indices into the
|
|
|
970 face cache, but the cache can be changed at various times,
|
|
|
971 which could make the current display structures incorrect.
|
|
|
972 I guess the dirty and updated flags are an attempt to fix
|
|
|
973 this, but this approach doesn't really work.
|
|
|
974
|
|
|
975 Here's an approach that should keep things clean and unconfused:
|
|
|
976
|
|
|
977 1) Imagine a "virtual face cache" that can grow arbitrarily
|
|
|
978 big and for which the only thing allowed is to add new
|
|
|
979 elements. Existing elements cannot be removed or changed.
|
|
|
980 This way, any pointers in the existing redisplay structure
|
|
|
981 into the cache never get screwed up. (This is important
|
|
|
982 because even if a cache element is out of date, if there's
|
|
|
983 a pointer to it then its contents still accurately describe
|
|
|
984 the way the text currently looks on the screen.)
|
|
|
985 2) Each element in the virtual cache either describes exactly
|
|
|
986 one face, or describes the merger of a number of faces
|
|
|
987 by some process. In order to simplify things, for mergers
|
|
|
988 we do not record which faces or ordering was used, but
|
|
|
989 simply that this cache element is the result of merging.
|
|
|
990 Unlike the current implementation, it's important that a
|
|
|
991 single cache element not be used to both describe a
|
|
|
992 single face and describe a merger, even if all the property
|
|
|
993 values are the same.
|
|
|
994 3) Each cache element can be clean or dirty. "Dirty" means
|
|
|
995 that the face that the element points to has been changed;
|
|
|
996 this gets set at the time the face is changed. This
|
|
|
997 way, when looking up a value in the cache, you can determine
|
|
|
998 whether it's out of date or not. For merged faces it
|
|
|
999 does not matter -- we don't record the faces or priority
|
|
|
1000 used to create the merger, so it's impossible to look up
|
|
|
1001 one of these faces. We have to recompute it each time.
|
|
|
1002 Luckily, this is fine -- doing the merge is much
|
|
|
1003 less expensive than recomputing the properties of a
|
|
|
1004 single face.
|
|
|
1005 4) For each cache element, we keep a hash value. (In order
|
|
|
1006 to hash the boolean properties, we convert each of them
|
|
|
1007 into a different large prime number so that the hashing works
|
|
|
1008 well.) This allows us, when comparing runes, to properly
|
|
|
1009 determine whether the face for that rune has changed.
|
|
|
1010 This will be especially important for TTY's, where there
|
|
|
1011 aren't that many faces and minimizing redraw is very
|
|
|
1012 important.
|
|
|
1013 5) We can't actually keep an infinite cache, but that doesn't
|
|
|
1014 really matter that much. The only elements we care about
|
|
|
1015 are those that are used by either the current or desired
|
|
|
1016 display structs. Therefore, we keep a per-window
|
|
|
1017 redisplay iteration number, and mark each element with
|
|
|
1018 that number as we use it. Just after outputting the
|
|
|
1019 window and synching the redisplay structs, we go through
|
|
|
1020 the cache and invalidate all elements that are not clean
|
|
|
1021 elements referring to a particular face and that do not
|
|
|
1022 have an iteration number equal to the current one. We
|
|
|
1023 keep them in a chain, and use them to allocate new
|
|
|
1024 elements when possible instead of increasing the Dynarr.
