This may result in an error, while we should just really just skip the corresponding path. Fixed by adding the new utily function `open_file`. | |

b5586a6c | 2016-12-02 22:15:19 | keysym: fix locale dependence in xkb_keysym_from_name() We currently use strcasecmp, which is locale-dependent. In particular, one well-known surprise even if restricted just ASCII input is found in the tr_TR (Turkish) locale, see e.g. https://msdn.microsoft.com/en-us/library/ms973919.aspx#stringsinnet20_topic5 We have known to avoid locale-dependent functions before, but in this case, we forgot. Fix it by implementing our own simple ASCII-only strcasecmp/strncasecmp. Might have been possible to use strcasecmp_l() with the C locale, but went the easy route. Side advantage is that even this non-optimized version is faster than the optimized libc one (__strcasecmp_l_sse42) since it doesn't need to do the locale stuff. xkb_keysym_from_name(), which uses strcasecmp heavily, becomes faster, and so for example Compose file parsing, which uses xkb_keysym_from_name() heavily, becomes ~20% faster.

eb348255 | 2013-07-20 23:21:44 | x11: add XKB protocol keymap and state creation support These are function to create an xkb_keymap directly from XKB requests to the X server. This opens up the possibility for X clients to use xcb + xcb-xkb + xkbcommon as a proper replacement for Xlib + xkbfile for keyboard support. The X11 support must be enabled with --enable-x11 for now. The functions are in xkbcommon/xkbcommon-x11.h. It depends on a recent libxcb with xkb enabled. The functions are in a new libxkbcommon-x11.so, with a new pkg-config file, etc. so that the packages may be split, and libxkbcommon.so itself remains dependency-free. Why not just use the RMLVO that the server puts in the _XKB_RULES_NAMES property? This does not account for custom keymaps, on-the-fly keymap modifications, remote clients, etc., so is not a proper solution in practice. Also, some servers don't even set it. Now, the client just needs to recreate the keymap in response to a change in the server's keymap (as Xlib clients do with XRefreshKeyboardMapping() and friends).

e44cd2e9 | 2012-09-24 10:55:20 | symbols: move keysyms into LevelInfo Instead of maintaining a syms array in the GroupInfo + sym_index's in the levels. This simplifies the code somewhat. In order not to alloc for every level instead of every group, we only do it if the level has more than one keysym (with a union).

db45d664 | 2012-09-10 13:34:36 | symbols: add GroupInfo GroupInfo keeps all of the info for a specific group in one struct. This is the old array-of-structures vs. structure-of-arrays, but in this case readability wins. It would also help with lifting the XkbNumKbdGroups limit, because we only have to worry about one array (instead of 6). Signed-off-by: Ran Benita <ran234@gmail.com> | |

f410622b | 2012-08-15 22:07:37 | vmod: remove support for resolving integer to virtual modifier This is only relevant to the virtualModifier= statement in interpret statements in xkb_compat. The current code allows to write e.g. virtualModifier = 4 to get the virtual modifier whose index happens to be 4 (possibly declared in other files or sections, i.e. xkb_types). Doing this is undeterministic, will break without notice, and not used anywhere. Don't allow it. Signed-off-by: Ran Benita <ran234@gmail.com> | |

06d7803a | 2012-08-30 12:13:37 | state: fix mod_names_are_active This function was always returning -1. Adding a test, we see that test/state.c treat the is_active functions as returning booleans, which would treat -1 as success, so we test for > 0 instead (most users would probably get this wrong as well...). Also update the documentation for the are_active functions, and add a ATTR_NULL_SENTINEL for gcc __attribute__((sentinel)). Signed-off-by: Ran Benita <ran234@gmail.com> | |

9de067aa | 2012-08-27 21:31:18 | compat: ignore "group" (compatibility) statements Group compatibility statements are like the following: group 3 = AltGr; This currently results in: keymap->groups[2].mask = <real mod mapped from AltGr vmod> And we don't do any thing with this value later. The reason it exists in XKB is to support non-XKB clients (i.e. XKB support disabled entirely in the server), which do not know the concept of "group", and use some modifier to distinguish between the first and second keyboard layouts (usually with the AltGr key). We don't care about all of that, so we can forget about it. One artifact of this removal is that xkb_map_num_groups no longer works, because it counted through keymap->groups (this wasn't entirely correct BTW). Instead we add a new num_groups member to the keymap, which just hold the maximum among the xkb_key's num_groups. This also means we don't have to compute anything just to get the number of groups.

70f35cfb | 2012-07-20 13:10:13 | Add logging API Add new public API to provide the library users with some options to control and customize the logging output from the library. It is based upon the skeleton from the libabc demo libray: https://git.kernel.org/?p=linux/kernel/git/kay/libabc.git which is public domain and works pretty well. This requires passing in the context object in every logging call, and thus the conversion is done file by file. We also remove the global warningLevel variable in favor of a verbosity level in the context, which can be set by the user and is silent by default. One issue is the ACTION calls, which, while nice, do not play very well with line- and priority-based logging, and would require some line continuation handling or keeping state or some other compromise. So instead remove these and just inline them with their respective warning/error. So instead of: ERROR("Memory allocation failed\n") ACTION("Removing all files on hardisk\n") its something like that: log_err("Memory allocation failed; Removing all files on harddisk\n") Signed-off-by: Ran Benita <ran234@gmail.com> | |
