Pierre Le Marre c0065c95 2023-09-21T20:06:27 Messages: merge macros with and without message code Previously we had two types of macros for logging: with and without message code. They were intended to be merged afterwards. The idea is to use a special code – `XKB_LOG_MESSAGE_NO_ID = 0` – that should *not* be displayed. But we would like to avoid checking this special code at run time. This is achieved using macro tricks; they are detailed in the code (see: `PREPEND_MESSAGE_ID`). Now it is also easier to spot the remaining undocumented log entries: just search `XKB_LOG_MESSAGE_NO_ID`.

Ran Benita 4a576ab1 2021-08-31T21:50:52 x11: try to fix crash in xkb_x11_keymap_new_from_device error handling In 1b3a1c277a033083fee669e92c8cad862716ebd1 we changed the error handling in this code to not bail out immediately but only after everything has been processed, to simplify the code. But I suspect the code isn't prepared for this and that's what causing the crash reported in the issue. Bring back the short-circuit error handling which would hopefully fix such crashes.

Ran Benita 29af25ea 2021-04-07T10:47:15 x11: fix xkb_x11_keymap_new_from_device failing when a level name is empty The numpad:mac option doesn't specify a name for the first level: // On Mac keypads, level 1 and 2 are swapped. partial xkb_types "mac" { type "KEYPAD" { modifiers = None; map[None] = Level2; level_name[Level2] = "Number"; }; include "extra(keypad)" }; This means the atom for level name is XCB_ATOM_NONE. We tried to get its name, which fails. This regressed in 40c00b472144d1684d2fb97cafef39. Instead, translate it to XKB_ATOM_NONE, same as the previous behavior.

Uli Schlachter c0339701 2021-03-07T09:24:40 Save another GetAtomName round trip Both get_atom_name() and the new atom interner required a round trip. Move get_atom_name() into the atom interner to save one more round trip. This brings xkb_x11_keymap_new_from_device() down to two round trips, which is the minimum possible number. (Also, I think the new code in keymap.c is more readable than the mess I previously created) With this last commit in the series, this definitely: Fixes: https://github.com/xkbcommon/libxkbcommon/pull/217 Signed-off-by: Uli Schlachter <psychon@znc.in>

Uli Schlachter 1b3a1c27 2021-03-07T08:42:54 Remove three more round trips There are a number of XKB requests needed to request all the information from the X11 server. So far, the code was sending one request and waiting for the reply. This commit starts batching the request so that we get multiple replies with one round trip. This removes three round trips. Only the simple requests are converted. get_map() and get_names() use some bitmasks that are needed for both the request and the reply. These will be dealt with separately.

Uli Schlachter b9707c1d 2021-03-07T08:01:49 Save three more round trips in xkb_x11_keymap_new_from_device() Instead of asking for an atom name and waiting for the reply four times, this now sends four GetAtomName requests and waits for all the replies at once. Thus, this saves three round trips. Signed-off-by: Uli Schlachter <psychon@znc.in>
Uli Schlachter 40c00b47 2021-03-07T07:42:28 xkb_x11_keymap_new_from_device: Less X11 round-trips On my system, calling xkb_x11_keymap_new_from_device() did 78 round trips to the X11 server, which seems excessive. This commit brings this number down to about 9 to 10 round trips. The existing functions adopt_atom() and adopt_atoms() guarantee that the atom was adopted by the time they return. Thus, each call to these functions must do a round-trip. However, none of the callers need this guarantee. This commit makes "atom adopting" asynchronous: Only some time later is the atom actually adopted. Until then, it is in some pending "limbo" state. This actually fixes a TODO in the comments.

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.

Ran Benita f00e779a 2014-08-08T17:21:28 x11/keymap: be more defensive about the number of modifiers There can be at most 16 vmods, and we rely on the facts that #vmods + NUM_REAL_MODS (8) <= XKB_MAX_MODS (32) when accessing keymap->mods.mods. But msb_pos() can potentially return up to #vmods = 32 if the server is malicious, so we need to truncate it. Signed-off-by: Ran Benita <ran234@gmail.com>

But XkbGetMap's virtualMods mask starts the virtual modifiers at zero, so we need to add an offset (like we do correctly in get_vmod_names()). https://github.com/xkbcommon/libxkbcommon/issues/9 Reported-by: @rtcm Signed-off-by: Ran Benita <ran234@gmail.com>

The is manifested when: - We've already gone through one batch (>= 128 atoms) (in fact this cannot happen in call to `adopt_atoms` in the current code). - An XCB request failed in the middle of a batch.

Ran Benita 9014cf8c 2014-04-22T13:15:21 keymap, keycodes, compat: don't use darray for LEDs Use a static array of size XKB_MAX_LEDS instead, as in xkb_mod_set. Signed-off-by: Ran Benita <ran234@gmail.com>
Ran Benita 787faf36 2014-04-22T12:23:36 keymap: don't use darray in xkb_mod_set Instead just statically allocate the mods array (of size MAX_MOD_SIZE = 32). The limit is not going anywhere, and static allocations are nicer (nicer code, no OOM, etc.). It's also small and dense enough. Signed-off-by: Ran Benita <ran234@gmail.com>
Ran Benita ca3170ad 2013-02-08T13:09:33 Add struct xkb_mod_set The only thing that the compilation phase needs the keymap for currently is for access to the modifier information (it also modifies it in place!). We want to only pass along the neccessary information, to make it more tractable and testable, so instead of passing the entire keymap we add a new 'mod_set' object and pass a (const) reference to that. The new object is just the old array of 'struct xkb_mod'. Signed-off-by: Ran Benita <ran234@gmail.com>
Ran Benita 3c14d233 2014-03-06T13:43:02 x11: relax XkbGetNames requirements It is valid for a keymap to not have key aliases, group names and various other things. But the current test requires all of them to be present in the reply, which causes us the fail on such keymaps (as the XQuartz one). Instead, require only what we really need. The virtual-mods names may not be strictly required, but it seems safer to leave it in for now. https://bugs.freedesktop.org/show_bug.cgi?id=75798 Reported-by: Gatis Paeglis <gatis.paeglis@digia.com> Signed-off-by: Ran Benita <ran234@gmail.com>

Ran Benita 973b8fd4 2014-02-08T16:40:20 api: deprecate XKB_MAP_COMPILE_PLACEHOLDER, and use KEYMAP instead of MAP The PLACEHOLDER was not meant to be used, but c++ doesn't like passing 0 to enums, so it was used. For this reason we add all the NO_FLAGS items, so the PLACEHOLDER shouldn't be used anymore. Second, XKB_MAP is the prefix we used ages ago, KEYMAP is the expected prefix here. So deprecate that as well. The old names may still be used through the xkbcommon-compat.h header, which is included by default (no need to include directly).

Ran Benita eb348255 2013-07-20T23:21:44 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).
