964 #### Here is a description of how the face cache elements ought
|
|
|
965 to be redone. It is *NOT* how they work currently:
|
|
|
966
|
|
|
967 However, when I started to go about implementing this, I realized
|
|
|
968 that there are all sorts of subtle problems with cache coherency
|
|
|
969 that are coming up. As it turns out, these problems don't
|
|
|
970 manifest themselves now due to the brute-force "kill 'em all"
|
|
|
971 approach to cache invalidation when faces change; but if this
|
|
|
972 is ever made smarter, these problems are going to come up, and
|
|
|
973 some of them are very non-obvious.
|
|
|
974
|
|
|
975 I'm thinking of redoing the cache code a bit to avoid these
|
|
|
976 coherency problems. The bulk of the problems will arise because
|
|
|
977 the current display structures have simple indices into the
|
|
|
978 face cache, but the cache can be changed at various times,
|
|
|
979 which could make the current display structures incorrect.
|
|
|
980 I guess the dirty and updated flags are an attempt to fix
|
|
|
981 this, but this approach doesn't really work.
|
|
|
982
|
|
|
983 Here's an approach that should keep things clean and unconfused:
|
|
|
984
|
|
|
985 1) Imagine a "virtual face cache" that can grow arbitrarily
|
|
|
986 big and for which the only thing allowed is to add new
|
|
|
987 elements. Existing elements cannot be removed or changed.
|
|
|
988 This way, any pointers in the existing redisplay structure
|
|
|
989 into the cache never get screwed up. (This is important
|
|
|
990 because even if a cache element is out of date, if there's
|
|
|
991 a pointer to it then its contents still accurately describe
|
|
|
992 the way the text currently looks on the screen.)
|
|
|
993 2) Each element in the virtual cache either describes exactly
|
|
|
994 one face, or describes the merger of a number of faces
|
|
|
995 by some process. In order to simplify things, for mergers
|
|
|
996 we do not record which faces or ordering was used, but
|
|
|
997 simply that this cache element is the result of merging.
|
|
|
998 Unlike the current implementation, it's important that a
|
|
|
999 single cache element not be used to both describe a
|
|
|
1000 single face and describe a merger, even if all the property
|
|
|
1001 values are the same.
|
|
|
1002 3) Each cache element can be clean or dirty. "Dirty" means
|
|
|
1003 that the face that the element points to has been changed;
|
|
|
1004 this gets set at the time the face is changed. This
|
|
|
1005 way, when looking up a value in the cache, you can determine
|
|
|
1006 whether it's out of date or not. For merged faces it
|
|
|
1007 does not matter -- we don't record the faces or priority
|
|
|
1008 used to create the merger, so it's impossible to look up
|
|
|
1009 one of these faces. We have to recompute it each time.
|
|
|
1010 Luckily, this is fine -- doing the merge is much
|
|
|
1011 less expensive than recomputing the properties of a
|
|
|
1012 single face.
|
|
|
1013 4) For each cache element, we keep a hash value. (In order
|
|
|
1014 to hash the boolean properties, we convert each of them
|
|
|
1015 into a different large prime number so that the hashing works
|
|
|
1016 well.) This allows us, when comparing runes, to properly
|
|
|
1017 determine whether the face for that rune has changed.
|
|
|
1018 This will be especially important for TTY's, where there
|
|
|
1019 aren't that many faces and minimizing redraw is very
|
|
|
1020 important.
|
|
|
1021 5) We can't actually keep an infinite cache, but that doesn't
|
|
|
1022 really matter that much. The only elements we care about
|
|
|
1023 are those that are used by either the current or desired
|
|
|
1024 display structs. Therefore, we keep a per-window
|
|
|
1025 redisplay iteration number, and mark each element with
|
|
|
1026 that number as we use it. Just after outputting the
|
|
|
1027 window and synching the redisplay structs, we go through
|
|
|
1028 the cache and invalidate all elements that are not clean
|
|
|
1029 elements referring to a particular face and that do not
|
|
|
1030 have an iteration number equal to the current one. We
|
|
|
1031 keep them in a chain, and use them to allocate new
|
|
|

|
|
|
1290 the only one dealing with images. The problem we have here is that
|
|
|
1291 frobbing the background pixmap might lead to image instantiation
|
|
|
1292 which in turn might require that the cache we're building be up to
|
|
|
1293 date, hence a crash. Here's a typical scenario of this:
|
|
|
1294
|
|
|
1295 - a new window is created and it's face cache elements are
|
|
|
1296 initialized through a call to reset_face_cachels[1]. At that point,
|
|
|
1297 the cache for the default and modeline faces (normaly taken care of
|
|
|
1298 by redisplay itself) are null.
|
|
|
1299 - the default face has a background pixmap which needs to be
|
|
|
1300 instantiated right here, as a consequence of cache initialization.
|
|
|
1301 - the background pixmap image happens to be instantiated as a string
|
|
|
1302 (this happens on tty's for instance).
|
|
|
1303 - In order to do this, we need to compute the string geometry.
|
|
|
1304 - In order to do this, we might have to access the window's default
|
|
|
1305 face cache. But this is the cache we're building right now, it is
|
|
|
1306 null.
|
|
|
1307 - BARF !!!!!
|
|
428
|
1308
|
|
446
|
1309 To sum up, this means that it is in general unsafe to instantiate
|
|
|
1310 images before face cache updating is complete (appart from image
|
|
|
1311 related face attributes). The solution we use below is to actually
|
|
|
1312 detect whether we're building the window's face_cachels for the first
|
|
|
1313 time, and simply NOT frob the background pixmap in that case. If
|
|
|
1314 other image-related face attributes are ever implemented, they should
|
|
|
1315 be protected the same way right here.
|
|
|
1316

|
1317 One note:
|
|
|
1318 * See comment in `default_face_font_info' in face.c. Who wrote it ?
