Ronan Pigott b4e81ca1 2022-12-16T01:26:25 context: add XKB_CONTEXT_NO_SECURE_GETENV flag (#312) This flag is useful for clients that may have relatively benign capabilities set, like CAP_SYS_NICE, that also want to use the xkb configuration from the environment and user configs in XDG_CONFIG_HOME.

Ran Benita 1bd3b3c7 2020-11-19T00:28:37 x11: cache X11 atoms On every keymap notify event, the keymap should be refreshed, which fetches the required X11 atoms. A big keymap might have a few hundred of atoms. A profile by a user has shown this *might* be slow when some intensive amount of keymap activity is occurring. It might also be slow on a remote X server. While I'm not really sure this is the actual bottleneck, caching the atoms is easy enough and only needs a couple kb of memory, so do that.

Peter Hutterer d7b39f6f 2020-07-10T08:50:02 Add /etc/xkb as extra lookup path for system data files This completes the usual triplet of configuration locations available for most processes: - vendor-provided data files in /usr/share/X11/xkb - system-specific data files in /etc/xkb - user-specific data files in $XDG_CONFIG_HOME/xkb The default lookup order user, system, vendor, just like everything else that uses these conventions. For include directives in rules files, the '%E' resolves to that path. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>

Peter Hutterer e23f1061 2019-10-25T14:36:16 Use XDG_CONFIG_HOME as first XKB search path Use $XDG_CONFIG_HOME/xkb as the primary lookup path for XKB rules. Same motivation as in 3a91788d9254b, however the XDG directories are more standard and recommended these days than application-specific dotfiles. The XDG spec says to fall back to $HOME/.config where XDG_CONFIG_HOME is not set so we implement that behavior as well. Fixes #112 Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>

Ran Benita 3a91788d 2019-10-03T17:27:00 context: move ~/.xkb to before XKB_CONFIG_ROOT in the default include path Previously, the default include path was XKB_CONFIG_ROOT:~/.xkb. The ~/.xkb include path is intended to allow the local user to customize their keymaps without having to modify system paths. But usually, the user only wants to customize specific parts. When XKB_CONFIG_ROOT is first, the user can only customize through the "entry point" (the RMLVO). When ~/.xkb is first, the user can drop in a file and it will override the system one. The impetus for this change is the rules file. "evdev" is hard-coded everywhere, so it not often not possible to change to something else. And the rules files determines how the rest of the RMLVO is interpreted. So, to enable customization, we have these options: A: System includes user. B: User includes system. C: Library goes over both in one or the other order. Option A is problematic due to backward compatibility and is also unnatural. Option B gives the user control and is backward compatible, so that's what we choose. This is also how Compose files are handled, and that seems to work fine in the wild. Option C is actually less flexible than B, and more complicated. (The rules file format doesn't have an include statement yet, but it's planned). Signed-off-by: Ran Benita <ran@unusedvar.com>
Michael Vogt 7ea129fb 2015-07-17T20:59:52 Add XKB_CONFIG_ROOT environment The XKB_CONFIG_ROOT environment allows overrding the build time DFLT_XKB_CONFIG_ROOT path.
Ran Benita 109fe705 2014-02-04T02:53:05 Use secure_getenv when available We probably don't want to get a privileged process to compile arbitrary keymaps. So we should be careful about the envvars which control include paths or default RMLVOs. But then secure_getenv is more sensible for everything we do. Signed-off-by: Ran Benita <ran234@gmail.com>

(posix at least has 'restrict' there). So those two actually never worked for more than one value (i.e. with a +). Fix that, and do the same cleanup to ModMaskText.

Ran Benita 112cccb1 2012-07-23T16:03:34 Some atom related optimizations We often get a strdup'd string, just to pass it over the atom_intern and then immediately free it. But atom_intern then strdup's it again (if it's not interned already); so instead we can have the interning "steal" the memory instead of allocing a new one and freeing the old one. This is done by a new xkb_atom_steal function. It also turns out, that every time we strdup an atom, we don't actually modify it afterwards. Since we are guaranteed that the atom table will live as long as the context, we can just use xkb_atom_text instead. This removes a some more dynamic allocations. For this change we had to remove the ability to append two strings, e.g. "foo" + "bar" -> "foobar" which is only possible with string literals. This is unused and quite useless for our purposes. xkb_atom_strdup is left unused, as it may still be useful.

Ran Benita 70f35cfb 2012-07-20T13:10:13 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>

Ran Benita 43bf4136 2012-07-14T15:19:12 Fix fileID mess A few problems here: * In e.g. keycodes.c the fileID field of the Info struct was never initialized to the id of the appropriate file, so it was always 0. There's some code which uses it, mostly for warnings. * Some of the fileID fields were unsigned char, which overflows several times, seeing as the ID in some of our tests can get > 1000 (because we reuse the context). * Some sign mismatches. * fileID vs file_id.

This is especially helpful with AC_USE_SYSTEM_EXTENSIONS, as _GNU_SOURCE and friends can have an effect by merely being defined, which can lead to some confusion if its effective for only half the files.

Move the _X_EXPORT's to the corresponding function definitions, and use straight extern "C" clauses instead of _XFUNCPROTOBEGIN/END.
