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947 because even if a cache element is out of date, if there's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

|
|
|
1246 the only one dealing with images. The problem we have here is that
|
|
|
1247 frobbing the background pixmap might lead to image instantiation
|
|
|
1248 which in turn might require that the cache we're building be up to
|
|
|
1249 date, hence a crash. Here's a typical scenario of this:
|
|
|
1250
|
|
|
1251 - a new window is created and it's face cache elements are
|
|
|
1252 initialized through a call to reset_face_cachels[1]. At that point,
|
|
|
1253 the cache for the default and modeline faces (normaly taken care of
|
|
|
1254 by redisplay itself) are null.
|
|
|
1255 - the default face has a background pixmap which needs to be
|
|
|
1256 instantiated right here, as a consequence of cache initialization.
|
|
|
1257 - the background pixmap image happens to be instantiated as a string
|
|
|
1258 (this happens on tty's for instance).
|
|
|
1259 - In order to do this, we need to compute the string geometry.
|
|
|
1260 - In order to do this, we might have to access the window's default
|
|
|
1261 face cache. But this is the cache we're building right now, it is
|
|
|
1262 null.
|
|
|
1263 - BARF !!!!!
|
|
428
|
1264
|
|
446
|
1265 To sum up, this means that it is in general unsafe to instantiate
|
|
|
1266 images before face cache updating is complete (appart from image
|
|
|
1267 related face attributes). The solution we use below is to actually
|
|
|
1268 detect whether we're building the window's face_cachels for the first
|
|
|
1269 time, and simply NOT frob the background pixmap in that case. If
|
|
|
1270 other image-related face attributes are ever implemented, they should
|
|
|
1271 be protected the same way right here.
|
|
|
1272
|
|
|
1273 One note:
|
|
|
1274 * See comment in `default_face_font_info' in face.c. Who wrote it ?
|
|
|
1275 Maybe we have the begining of an answer here ?
