500b260b | 2025-03-28 09:38:58 | xkbcomp: Fix parser failure on floating-point numbers Before this commit we used `strtold`, which depends on the locale. But the XKB syntax is fixed and uses a period as decimal separator. So ensure the syntax is correct without relying on `strtold` and truncate the result, as the parser does not use floating-point numbers. | |

e8561909 | 2025-03-18 14:34:10 | xkbcomp: Fix keycodes bounds - Refactor to check conflicts first for the key names and then for the keycodes. This seems more useful for the user and enable further memory optimizations. - Do not allocate until we are sure to add the keycode. The bounds are only updated afterwards, so the call to `FindKeyByName` should be more efficient. - Fixed keycodes bounds not shrunk correctly when an existing keycode is overridden. - Do not prepare keyname strings for logging if we are not going to use them. | |

4e90cb9c | 2025-03-17 07:02:07 | xkbcomp: Improve logging of virtual modifiers When logging about virtual modifier *explicit* mappings, we should always use only real modifiers or hexadecimal numbers to print the mask. Consider: ``` virtual_modifiers M1, M2=0x200, M2=0x400; ``` Before this commit we would get the following warning: ``` WARNING: Virtual modifier M2 defined multiple times; Using M2, ignoring M1 ``` while we would prefer the less confusing: ``` WARNING: Virtual modifier M2 defined multiple times; Using 0x400, ignoring 0x200 ``` | |

9953d9f0 | 2025-03-10 21:58:05 | xkbcomp/ast-build: fix possible UB in expr AST node allocations (#659) The expression AST constructors all return `ExprDef *`. `ExprDef` is a union of all expr types. As a memory optimization, instead of allocating `sizeof(ExprDef)`, we only allocate the size of the actual type (e.g. `sizeof(ExprBinary)`) which is sometimes smaller than `sizeof(ExprDef)`. This is probably undefined behavior, and gcc (with optimization turned on) complains about it, for example: src/xkbcomp/ast-build.c:69:23: warning: array subscript ‘ExprDef[0]’ is partly outside array bounds of ‘unsigned char[24]’ [-Warray-bounds=] Since it doesn't save that much memory, drop this optimization.

cb3565b1 | 2025-03-07 17:59:33 | keymap: Fix segfault due to invalid group wrapping The modular arithmetic is incorrect for negative values, e.g. for num_groups = 1. It triggers a segfault for the following settings: - layouts count (per key or total) N: `N > 0`, and - layout index n: `n = - k * N` (`k > 0`) % returns the *remainder* of the division, not the modulus (see C11 standard 6.5.5 “Multiplicative operators”: a % b = a - (a/b)*b. While both operators return the same result for positive operands, they do not for e.g. a negative dividend: remainder may be negative (in the open interval ]-num_groups, num_groups[) while the modulus is always positive. So if the remainder is negative, we must add `num_groups` to get the modulus.

aa3e4c71 | 2025-02-07 14:10:16 | xkbcomp/expr: remove unused ExprResolveKeyCode This function was added in commit 4e22851141d89436c0659e68da57e91bbf971461. But that commit also changed the grammar: -KeyNameDecl : KeyName EQUALS Expr SEMI +KeyNameDecl : KeyName EQUALS KeyCode SEMI i.e. while before you could write <AE01> = 9+1; now this is a syntax error, an integer literal is expected. I'm not sure if it was intended to remove this ability. In any case, this rendered `ExprResolveKeyCode` useless since there's no longer an expression to evaluate, and after some refactoring it went unused. Even if we choose to restore Expr here, I don't see a reason for the specialized function over `ExprResolveInteger` except the type (which we should probably widen from int to int64_t...). So remove it. Signed-off-by: Ran Benita <ran@unusedvar.com> | |

26807a90 | 2025-01-28 20:24:05 | scanner: compute token line/column lazily on errors The scanner functions are hot, and the line/column location tracking is quite expensive. We only use it for errors, which don't need to be fast, because we bail if there are too many; and for warnings, which are usually not shown by default. So only keep the token start pos, and compute the line/column lazily from that. This will also allow some further improvements ahead. bench/rulescomp before: compiled 1000 keymaps in 1.669028s after: compiled 1000 keymaps in 1.550411s bench/compose: before: compiled 1000 compose tables in 2.145217s after: compiled 1000 compose tables in 2.016044s Signed-off-by: Ran Benita <ran@unusedvar.com> | |

502e9e5b | 2025-01-29 12:19:10 | xkbcomp: Add stricter bounds for keycodes and levels Our current implementation uses continuous arrays indexed by keycodes and levels. This is simple and good enough for realistic keymaps. However, they are allowed to have big values that will lead to either memory exhaustion or a waste of memory (sparse arrays). Added the much stricter upper bounds `0xfff` for keycodes[^1] and 2048 for levels[^2], which should still be plenty enough and provides stronger memory security. [^1]: Current max keycode is 0x2ff in Linux. [^2]: Should be big enough to satisfy automatically generated keymaps. | |

|
4ac22263 | 2025-01-16 23:22:40 | keysyms: Check clashes between keysyms names and keywords Due to how our parser is implemented, keysyms names that are also valid keywords require special handling. Added a check for these clashes in the keysym generator. The only current clash, `section`, is already handled. Note that it means that e.g. `section`, `Section` and `sEcTiOn` all parse to the same keysym. This side effect is fine here, because *currently* there is no other keysym that clashes with any possible of the case variation of `section`. But in order to be extra cautious, we now test thoses clashes too. Hopefully we will never have a clash again, but while it is unlikely that we modify the keywords, the keysyms are not a frozen set. | |

b9b4ab47 | 2024-12-09 09:21:01 | keysyms: Add sharp S upper case mapping exception The case mapping `ssharp` ß ↔ `U1E9E` ẞ was added in 13b30f4f0dccc08dfea426d73570b913596ed602 but was broken: - For the lower case mapping it returned the keysym `0x10000df`, which is an invalid Unicode keysym. - For the upper case mapping it returned the upper Unicode code point rather than the corresponding keysym. It did accidentally enable the detection of alphabetic key type for the pair (ß, ẞ) though. However this detection was accidentally removed in 5c7c79970a2800b6248e829464676e1f09c5f43d (v1.7) with an attempt to fix the wrong keysym case mapping. Finally both the *lower* case mapping and the key type detection were fixed for good when we implemented the complete Unicode simple case mappings and corresponding tests in e83d08ddbc9851944c662c18e86d4eb0eff23e68. However, the *upper* case mapping `ssharp` → `U1E9E` remained disabled. Indeed, ẞ is a relatively recent addition to Unicode (2008) and had no official recommendation, until recently. So while the lower mapping ẞ→ß exists in Unicode, its converse upper mapping does not. Yet since 2017 the Council for German Orthography (Rat für deutsche Rechtschreibung) recommends[^1] ẞ as the capitalization of ß. Due to its stability policies, the Unicode Character Database (UCD) that we use to generate our keysym case mappings (via ICU) cannot update the simple case mapping of ß. Discussions are currently ongoing in the Unicode mailing list[^2] and CLDR[^3] about how to deal with the new recommended case mapping. However, the discussions are oriented on text-processing and compatibility mappings, while libxkbcommon is on a rather lower level. It seems that the slow adoption of ẞ is partly due to the difficulty to type it. Since ẞ is used only for ALL CAPS casing, the expectation is to type it using CapsLock. While our detection of alphabetic key types works well[^4] for the pair (ß,ẞ), the *internal capitalization* currently does not work and is fixed by this commit. Added the ß → ẞ upper mapping: - Added an exception in the generation script - Fixed tests - Added documentation of the exceptions in `xkbcommon.h` - Added/updated log entries [^1]: https://www.rechtschreibrat.com/regeln-und-woerterverzeichnis/ [^2]: https://corp.unicode.org/pipermail/unicode/2024-November/011162.html [^3]: https://unicode-org.atlassian.net/browse/CLDR-17624 [^4]: Except libxkbcommon 1.7, see the second paragraph. | |

5fbc0ec7 | 2024-10-14 16:05:52 | state: Support querying whether virtual mods are consumed Previously it was not possible to query the status of virtual modifiers with the following functions: - `xkb_state_mod_index_is_consumed` - `xkb_state_mod_index_is_consumed2` Note that it may *overmatch* if some modifier mappings overlap. For example, the default “us” PC layout maps both “Alt” and “Meta” to the real modifier “Mod1”; thus “Mod1”, “Alt” and “Meta” modifiers will return the same result with these functions. | |
