Currently there is no direct way to know the minimum and maximum keysym
values that are assigned, i.e. that have an explicit name or are
Unicode keysyms.
Introduce the new following internal API:
- XKB_KEYSYM_MIN_ASSIGNED
- XKB_KEYSYM_MAX_ASSIGNED
- XKB_KEYSYM_MIN_EXPLICIT
- XKB_KEYSYM_MAX_EXPLICIT
- XKB_KEYSYM_COUNT_EXPLICIT
Also add a bunch of tests to ensure consistant keysyms bounds.
I couldn't find any reference to *how* the keymap format actually needs to look
like if you want multiple keysyms per level. So let's add a test for it and a
minimal documentation entry.
Previously the attribute “popularity” was completely ignored. It also
did not respect the modified DTD, because its default value depends if
we are currently parsing an “extras” rules file.
Fixed:
- Always parse the popularity attribute.
- Change the DTD to reflect that the default value is implied.
- Add check for recursive includes of keymap components. It relies on
limiting the include depth. The threshold is currently to 15, which
seems reasonable with plenty of margin for keymaps in the wild.
- Add corresponding new log message `recursive-include`.
- Add tests for recursive includes.
Leading BOM is legal and is used as a signature — an indication that
an otherwise unmarked text file is in UTF-8.

- Update keymap to use reference keysym names.
- Fix x11comp test by handling old x11proto.
We need xkbcomp to be compiled with at least x11proto-dev 2023.2.
So we replace the unsupported keysyms with supported ones not
already in the keymap. This is kind of ugly, but it works. If we
ever want to restore the original keysyms with their supported names,
the substitute keysyms will be easy to spot.
The octal parser accepts the range `\1..\777`. The result is cast to
`char` which will silently overflow.
This commit prevents overlow and will treat `\400..\777` as invalid
escape sequences.
NULL usually terminates the strings; allowing to produce it via escape
sequences may lead to undefined behaviour.
- Make NULL escape sequences (e.g. `\0` and `\x0`) invalid.
- Add corresponding test.
- Introduce the new message: XKB_WARNING_INVALID_ESCAPE_SEQUENCE.
Allow users to iterate the entries in a compose table. This is useful
for other projects which want programmable access to the sequences,
without having to write their own parser.
- New API:
- `xkb_compose_table_entry_sequence`;
- `xkb_compose_table_entry_keysym`;
- `xkb_compose_table_entry_utf8`;
- `xkb_compose_table_iterator_new`;
- `xkb_compose_table_iterator_free`;
- `xkb_compose_table_iterator_next`.
- Add tests in `test/compose.c`.
- Add benchmark for compose traversal.
- `tools/compose.c`:
- Print entries instead of just validating them.
- Add `--file` option.
- TODO: make this tool part of the xkbcli commands.

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`.
This tool checks whether messages codes are supported.
This is useful e.g. for CI, where one may want to grep for some XKB
error codes and ensure that these are still supported.
Based on the work done by Peter Hutterer. Original commit message:
If SIGUSR1 is set to SIG_IGN, X servers (all of them, including Xvfb)
will send that signal to the parent process when they're ready to accept
connections. We can use that instead of a hardcoded sleep which brings
the wait down to ~37ms on my box.
The x11 test is currently silently skipped in CI, because it requires a
running X server.
Create a xvfb wrapper to run the test. We do not use `xvfb-run`, because
it is a shell script and it causes valgrind to detect unrelated memory
issues in the shell (dash, bash).
Improve wrapper using a special ELF section
TODO: The wrapper is intended to be used with the x11comp test as well.
- Add a keymap test with decimal and hexadecimal keysyms.
- Reorganize code in `test/keysym.c` by parsing type: name, Unicode and
hexadecimal.
- Add more tests for edge cases. In particular:
- test decimal format (currently not supported);
- test the Unicode and hexadecimal ranges more thoroughly;
- test with wrong case without the XKB_KEYSYM_CASE_INSENSITIVE flag;
- test surrounding spaces.
- Document the tests.
The test `test_from_locale` fails when there is a user-defined compose
file, e.g. ~/.XCompose.
Indeed, the function `xkb_compose_table_new_from_locale` use various
environment variables to determine the location of the compose file.
Ensure no environment variables but the required ones are set, in order
to have robust tests.
As the documentation for xkb_keymap_new_from_buffer() states, the "input string
does not have to be zero-terminated". The actual implementation however failed
with "unrecognized token/syntax error" when it encountered a null byte.
Fix this by allowing a null byte at the last position of the buffer. Anything
else is likely a client error anyway.
Fixes#307
Unlike current xkbcommon, X11’s xkbcomp allows to remove entries in
the modifiers’ map using “modifier_map None { … }”.
“None” is translated to the special value “XkbNoModifier” defined in
“X11/extensions/XKB.h”. Then it relies on the fact that in "CopyModMapDef",
the following code:
1U << entry->modifier
ends up being zero when “entry->modifier” is “XkbNoModifier” (i.e. 0xFF).
Indeed, it relies on the overflow behaviour of the left shift, which in
practice resolves to use only the 5 low bits of the shift amount, i.e.
0x1F here. Then the result of “1U << 0xFF” is cast to “char”, i.e. 0.
This is a good trick but too magical, so in libxkbcommon we will use
an explicit test against our new constant XKB_MOD_NONE.
`_MSC_VER` is specific to MSVC, but there can be other compilers targeting
windows. Hopefully they do define `_WIN32`, so let's use that.

Not sure what it's doing here, but converting "€" to a keysym
doesn't work with this entry. 0x13a4 doesn't appear in
xkbcommon-keysyms.h. 0x20ac is the keysym documented in the
header (and it's the last entry in the table).
It's been in the table since it was introduced in e0524296d2
("Add API for getting unicode representation of a keysym").

lokid and hikid actually stores the sibling to current node, which
should not be cleared when override. This would break the sequence with
a common prefix when override another.

This is hit when passing an empty string and XKB_KEYSYM_CASE_INSENSITIVE
to xkb_keysym_from_name currently if `(lo + hi) / 2` is 0 and `cmp < 0`,
causing mid to underflow and the the array access into name_to_keysym on
the next iteration of the loop to be out of bounds .
We *would* use ssize_t here as it is the appropriate type, but windows
unfortunately does not define it.
Add a skipError test function that can analyse rc, stdout, stderr to skip a test
even when we expect an error. We use that to skip if we couldn't find a keyboard
in the interactive-evdev test.
