0071227e | 2012-08-26 08:54:31 | rules: rewrite Rewrite the rules file parser for clarity, performance and memory usage reduction. The previous implementation was quite hard to navigate and did a lot of unnecessary work and copying. This implementation keeps along just the state necessary, and doesn't perform any copying of the file's content (although the entire file is mmap'ed as before). Hopefully it's also easier to understand, has better documentation, and better error checking and reporting. We try to reproduce the previous behavior in every case. Note: the diff is pretty confusing; it's likely better to look at the file directly.

7f04ffc4 | 2012-08-29 12:10:28 | rules: fix check for appending '|' character when applying There are two ways to separate multiple files in XKB include statements: '+' will cause the later file to override the first in case of conflict, while '|' will cause it augment it (this is done by xkbcomp). '!' is unrelated here. Since '|' is practically never used, this wasn't noticed. In the modified test, the '|some_compat' previously was just ignored. Signed-off-by: Ran Benita <ran234@gmail.com> | |

cdc228ea | 2012-08-13 11:00:43 | Organize xkbcomp/ header files Various non-functional changes: - Re-add keycodes.h and move some stuff there. - Add parser-priv.h for internal bison/flex stuff. - Don't include headers from other headers, such that file dependencies are immediate in each file. - Rename xkbcomp.h -> ast.h, parseutils.{c,h} -> ast-build.{c,h} - Rename path.{c,h} -> include.{c,h} - Rename keytypes.c -> types.c - Make the naming of XkbFile-related functions more consistent. - Move xkb_map_{new,ref,unref} to map.c. - Remove most extern keyword from function declarations, it's just noise (XKB_EXPORT is what's important here). - Append XKBCOMP_ to include guards. - Shuffle some code around to make all of this work. Splitting this would be a headache.. Signed-off-by: Ran Benita <ran234@gmail.com> | |

37f43849 | 2012-06-30 00:49:41 | rules: remove support for keymap rule This commit removes the ability to specify a keymap *in a rules file*, e.g. in /usr/share/X11/xkb/rules/evdev or somesuch. This is unused in xkeyboard-data, and the current code has never even supported it, because xkb_map_new_from_kccgst (which is no longer exposed in the API) checks to see that one of the usual components (e.g. symbols, types, ..) has been filled, while the rules parser, on the other hand, doesn't allow to specify a keymap and other stuff at the same time. ( The idea was to remove xkb_map_new_from_kccgst entirely, but it's used by a test so it can stay. ) tl;dr: dead code. Of course passing a keymap file to xkb_map_new_from_file still works.

bc50cdd4 | 2012-06-05 18:46:24 | darray: some changes for convenience - Make darray_free also initialize the array back to an empty state, and stop worrying about it everywhere. - Add darray_mem, to access the underlying memory, which we do manually now using &darray_item(arr, 0). This makes a bit more clear when we actually mean to take the address of a specific item. - Add darray_copy, to make a deep copy of a darray. - Add darray_same, to test whether two darrays have the same underlying memory (e.g. if the struct itself was value copied). This should used where previously two arrays were compared for pointer equality. Signed-off-by: Ran Benita <ran234@gmail.com> | |

57f184e2 | 2012-05-30 15:55:21 | darray: tweak parameters a bit for better memory usage Here are some quick numbers from valgrind, running rulescomp only with a simple, common "us,de" rule set: before darray: cb047bb total heap usage: 44,924 allocs, 44,924 frees, 3,162,342 bytes allocated after darray: c87468e total heap usage: 52,670 allocs, 52,670 frees, 2,844,517 bytes allocated tweaking specific inital allocation sizes: total heap usage: 52,652 allocs, 52,652 frees, 2,841,814 bytes allocated changing initial alloc = 2 globally total heap usage: 47,802 allocs, 47,802 frees, 2,833,614 bytes allocated changing initial alloc = 3 globally total heap usage: 47,346 allocs, 47,346 frees, 3,307,110 bytes allocated changing initial alloc = 4 globally total heap usage: 44,643 allocs, 44,643 frees, 2,853,646 bytes allocated [ Changing the geometric progression constant from 2 only made things worse. I tried the golden ratio - not so golden :) ] The last one is obviously the best, so it was chosen, with the specific tweaks thrown in as well (these were there before but don't make much difference). Overall it seems to do better than the previous manual allocations which is a bit surprising. Signed-off-by: Ran Benita <ran234@gmail.com> | |

68edd5f0 | 2012-05-19 12:50:47 | rules: allow wildcard match against "" layout/varaint Currently, if you pass in an rmlvo with an empty string for layout or variant, it would not match layout and variant rules even with wildcards. But if the rules file had set an appropriate default, and someone passes in the empty string, than he should get the default. NULL in this case signifies not wanting to match against the layout or variant at all, and so the rule should still fail to match NULLs. Signed-off-by: Ran Benita <ran234@gmail.com> | |
