917 #### Here is a description of how the face cache elements ought
|
|
918 to be redone. It is *NOT* how they work currently:
|
|
919
|
|
920 However, when I started to go about implementing this, I realized
|
|
921 that there are all sorts of subtle problems with cache coherency
|
|
922 that are coming up. As it turns out, these problems don't
|
|
923 manifest themselves now due to the brute-force "kill 'em all"
|
|
924 approach to cache invalidation when faces change; but if this
|
|
925 is ever made smarter, these problems are going to come up, and
|
|
926 some of them are very non-obvious.
|
|
927
|
|
928 I'm thinking of redoing the cache code a bit to avoid these
|
|
929 coherency problems. The bulk of the problems will arise because
|
|
930 the current display structures have simple indices into the
|
|
931 face cache, but the cache can be changed at various times,
|
|
932 which could make the current display structures incorrect.
|
|
933 I guess the dirty and updated flags are an attempt to fix
|
|
934 this, but this approach doesn't really work.
|
|
935
|
|
936 Here's an approach that should keep things clean and unconfused:
|
|
937
|
|
938 1) Imagine a "virtual face cache" that can grow arbitrarily
|
|
939 big and for which the only thing allowed is to add new
|
|
940 elements. Existing elements cannot be removed or changed.
|
|
941 This way, any pointers in the existing redisplay structure
|
|
942 into the cache never get screwed up. (This is important
|
|
943 because even if a cache element is out of date, if there's
|
|
944 a pointer to it then its contents still accurately describe
|
|
945 the way the text currently looks on the screen.)
|
|
946 2) Each element in the virtual cache either describes exactly
|
|
947 one face, or describes the merger of a number of faces
|
|
948 by some process. In order to simplify things, for mergers
|
|
949 we do not record which faces or ordering was used, but
|
|
950 simply that this cache element is the result of merging.
|
|
951 Unlike the current implementation, it's important that a
|
|
952 single cache element not be used to both describe a
|
|
953 single face and describe a merger, even if all the property
|
|
954 values are the same.
|
|
955 3) Each cache element can be clean or dirty. "Dirty" means
|
|
956 that the face that the element points to has been changed;
|
|
957 this gets set at the time the face is changed. This
|
|
958 way, when looking up a value in the cache, you can determine
|
|
959 whether it's out of date or not. For merged faces it
|
|
960 does not matter -- we don't record the faces or priority
|
|
961 used to create the merger, so it's impossible to look up
|
|
962 one of these faces. We have to recompute it each time.
|
|
963 Luckily, this is fine -- doing the merge is much
|
|
964 less expensive than recomputing the properties of a
|
|
965 single face.
|
|
966 4) For each cache element, we keep a hash value. (In order
|
|
967 to hash the boolean properties, we convert each of them
|
|
968 into a different large prime number so that the hashing works
|
|
969 well.) This allows us, when comparing runes, to properly
|
|
970 determine whether the face for that rune has changed.
|
|
971 This will be especially important for TTY's, where there
|
|
972 aren't that many faces and minimizing redraw is very
|
|
973 important.
|
|
974 5) We can't actually keep an infinite cache, but that doesn't
|
|
975 really matter that much. The only elements we care about
|
|
976 are those that are used by either the current or desired
|
|
977 display structs. Therefore, we keep a per-window
|
|
978 redisplay iteration number, and mark each element with
|
|
979 that number as we use it. Just after outputting the
|
|
980 window and synching the redisplay structs, we go through
|
|
981 the cache and invalidate all elements that are not clean
|
|
982 elements referring to a particular face and that do not
|
|
983 have an iteration number equal to the current one. We
|
|
984 keep them in a chain, and use them to allocate new
|
|
985 elements when possible instead of increasing the Dynarr.
