This test contains of two parts:
- a simple program to convert RMLVO commandline arguments into a keymap (and
print that keymap if requested).
- a python script that runs through rules/evdev.xml, and tries to compile a
keymap for sort-of every layout/variant/option combination. Sort-of, because
we can have multiple options and it really only does one per layout(variant)
combination.
Same thing can be done using xkbcomp, but right now it doesn't take that as
argument, it's hard-coded.
This takes quite a while, installing python-tqdm is recommended to see fancy

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.

The current functions dealing with consumed modifiers use the
traditional XKB definition of consumed modifiers (see description in the
added documentation). However, for several users of the library (e.g.
GTK) this definition is unsuitable or too eager. This is exacerbated by
some less-than-ideal xkeyboard-config type definitions (CTRL+ALT seems
to cause most grief...).
So, because we
- want to enable alternative interpretations, but
- don't want to expose too much internal details, and
- want to keep things simple for all library users,
we add a high-level "mode" parameter which selects the desired
interpretation. New ones can be added as long as they make some sense.
All of the old consumed-modifiers functions keep using the traditional
("XKB") mode. I mark xkb_state_mod_mask_remove_consumed() and as
deprecated without adding a *2 variant because I don't it is very useful
(or used) in practice.
Alternative modes are added in subsequent commits (this commit only adds
a mode for the existing behavior).

The `test/data/keymaps/host.xkb` file contains a duplicate definition of
this type. On my computer (linux, xkbcomp 1.3.0, xserver 1.17.2), the
test passes as is, but if I remove the duplicate definition, the
roundtrip brings it back and the test fails. I can also reproduce it
without relation to the test, by loading `test/data/keymaps/host.xkb`
(without the duplicate) using
xkbcomp -I $(pwd)/test/data/keymaps/host.xkb $DISPLAY
and downloading it again using
xkbcomp $DISPLAY out.xkb
the duplicate is added. On Mac OS X however, the duplicate is removed
(correctly), so the test fails there.
xkbcommon itself, which was forked from xkbcomp, doesn't have this bug;
in fact, doing
./test/print-compiled-keymap -k keymaps/host.xkb
removes the duplicate if it is present.
This is (probably) a regression in xkbcomp or xserver compared to the
versions used in Mac OS X. Since getting a patch for any of these two is
hopeless from my experience, I did not try to investigate further.
I am not sure why, but if I also add a `PC_SUPER_LEVEL2` type, the
duplicate of `FOUR_LEVEL_KEYPAD` doesn't show up. Hopefully the test
will work on all platforms now.

The current calculation is in short:
entry ? (entry->mask & ~entry->preserve) : 0
This changes it be
type->mask & ~(entry ? entry->preserve : 0)
This is what Xlib does. While less intuitive, it is actually more
correct, if you follow this deduction:
- The key group's type->mask defines which modifiers the key even cares
about. The others are completely irrelevant (and in fact they are
masked out from all sided in the level calculation). Example: NumLock
for an alphabetic key.
- The type->mask, the mods which are not masked out, are *all* relevant
(and in fact in the level calculation they must match *exactly* to the
state). These mods affect which level is chosen for the key, whether
they are active or not.
- Because the type->mask mods are all relevant, they must be considered
as consumed by the calculation *even if they are not active*.
Therefore we use type->mask instead of entry->mask.
The second change is what happens when no entry is found: return 0 or
just take preserve to be 0? Let's consider an example, the basic type
type "ALPHABETIC" {
modifiers = Shift+Lock;
map[Shift] = Level2;
map[Lock] = Level2;
level_name[Level1] = "Base";
level_name[Level2] = "Caps";
};
Suppose Shift+Lock is active - it doesn't match any entry, thus it gets
to level 0. The first interpretation would take them both to be
unconsumed, the second (new one) would take them both to be consumed.
This seems much better: Caps is active, and Shift disables it, they both
do something.
This change also fixes a pretty lousy bug (since 0.3.2), where Shift
appears to apparently *not* disable Caps. What actually happens is that
Caps is not consumed (see above) but active, thus the implicit
capitalization in get_one_sym() kicks in and capitalizes it anyway.

These functions generally have the same effect as
xkb_state_key_get_syms() + xkb_keysym_to_utf{8,32}().
So why add them?
- They provide a slightly nicer interface, especially if the string is
the only interest.
- It makes the handling of multiple-keysyms-to-utf8 transparent. For the
designated use-case of multiple-keysyms (unicode combining
characters), this is a must. We also validate the UTF-8, which the
user might not otherwise do.
- We will need to apply some transformation on the resulting string
which depend on the xkb_state. This is not possible with the
xkb_keysym_* functions.
With these functions, the existing xkb_keysym_to_utf{8,32}() are not

The xkbproto spec says:
http://www.x.org/releases/current/doc/kbproto/xkbproto.html#Interpreting_the_Lock_Modifier
If the Lock modifier is not consumed by the symbol lookup process,
routines that determine the symbol and string that correspond to
an event should capitalize the result.
This was not an issue until now, because most xkeyboard-config keymaps
do not utilize this "feature", and specify the keysyms for the Lock
modifier explicitly instead. However, some keymaps do depend on it, e.g.
ch(fr) for eacute and others.
The spec goes on to describe two options for doing this transformation:
locale-sensitive and locale-insensitive. We opt for the latter; it is
less desirable but we don't want *that* headache.
Also, only xkb_state_key_get_one_sym() is changed;
xkb_state_key_get_syms() is left as-is, and always reports the
untransformed keysyms. This is for the following reasons:
- The API doesn't allow it, since we return a const pointer directly to
the keymap keysyms table and we can't transform that.
- The transformation doesn't make sense for multiple-keysyms.
- It can be useful for an application to get the "raw" keysyms if it
wants to (e.g. maybe it wants to do the transformation itself).
Finally, note that xkb_state_mod_index_is_consumed() does *not*
report Lock as consumed even if it was used in the transformation. This
is what Xlib does.
This definitely doesn't fall under the "hard to misuse" API rule but
it's the best we can do.

The current API doesn't allow the caller to create keymaps from mmap()'ed
files. The problem is, xkb_keymap_new_from_string() requires a terminating
0 byte. However, there is no way to guarantee that when using mmap() so a
user currently has to copy the whole file just to get the terminating zero
byte (assuming they cannot use xkb_keymap_new_from_file()).
This adds a new entry xkb_keymap_new_from_buffer() which takes a memory
location and the buffer size in bytes.
Internally, we depend on yy_scan_{string,byte}() helpers. According to
flex documentation these already copy the input string because they are
wrappers around yy_scan_buffer().
yy_scan_buffer() on the other hand has some insane requirements. The
buffer must be writeable and the last two bytes must be ASCII-NUL. But the
buffer may contain other 0 bytes just fine.
Because we don't want these constraints in our public API,
xkb_keymap_new_from_buffer() needs to create a copy of the input memory.
But it then calls yy_scan_buffer() directly. Hence, we have the same
number of buffer-copies as with *_from_string() but without the
terminating 0 requirement.
The explicit yy_scan_buffer() call is preferred over yy_scan_byte() so the
buffer-copy operation is not hidden somewhere in flex.
Maybe some day we no longer depend on flex and can have a zero-copy API. A
user could mmap() a file and it would get parsed right from this buffer.
But until then, we shouldn't expose this limitation in the API but instead
provide an API that some day can work with zero-copy.

Recent xkeyboard-config introduced the following line in symbols/level3:
vmods = LevelThree,
However, the XKM format which xkbcomp produces for the X server can't
handle explicit virtual modifiers such as this:
https://bugs.freedesktop.org/show_bug.cgi?id=4927
So by doing the following, for example:
setxkbmap -layout de (or another 3-level layouts)
xkbcomp $DISPLAY out.xkb
xkbcomp out.xkb $DISPLAY
The modifier is lost and can't be used for switching to Level3 (see the
included test).
We, however, are affected worse by this bug when we load the out.xkb
keymap. First, the FOUR_LEVEL_ALPHABETIC key type has these entries:
map[None] = Level1;
map[Shift] = Level2;
map[Lock] = Level2;
map[LevelThree] = Level3;
[...]
Now, because the LevelThree virtual modifier is not bound to anything,
the effective mask of the "map[LevelThree]" entry is just 0. So when
the modifier state is empty (initial state), this entry is chosen, and
we get Level3, instead of failing to match any entry and getting the
default Level1.
The difference in behavior from the xserver stems from this commit:
acdad6058d
Which removed the entry->active field. Without bugs, this would be
correct; however, it seems in this case we should just follow the
server's behavior.
The server sets the entry->active field like so in XKBMisc.c:
/* entry is active if vmods are bound */
entry->active = (mask != 0);
The xkblib spec explains this field, but does not specify how to
initialize it. This commit does the same as above but more directly.

numbers this benchmark gives, it is pretty clear that we are not going
to be the bottleneck for anything. So this can more-or-less be ignored.
Incidentally, this also turned out to be a poor man's fuzzer, because it
turned up the fix in the previous commit. Maybe we should consider
beefing it up with an actual 'break stuff' intention and running it as
part of 'make check'.

This is the more appropriate for a specific key (also considering the
num_layouts() is a bit of a made-up value).

Note first:
This commits breaks the ABI somewhat. If an application is run against
this commit without recompiling against the updated header, these break:
- xkb_state_layout_*_is_active always retuns false.
- xkb_state_serialize_mods always returns 0.
So it might break layout switching in some applications. However,
xkbcommon-compat.h provides the necessary fixes, so recompiling should
work (though updating the application is even better).
Split the enum to its individual components, which enables us to refer
to them individually. We will use that later for reporting which
components of the state have changed after update.

This adds a flags argument to xkb_keysym_from_name() so we can perform a
case-insensitive search. This should really be supported as many keysyms
have really weird capitalization-rules.
However, as this may produce conflicts, users must be warned to only use
this for fallback paths or error-recovery. This is also the reason why the
internal XKB parsers still use the case-sensitive search.
This also adds some test-cases so the expected results are really
produced. The binary-size does _not_ change with this patch. However,
case-sensitive search may be slightly slower with this patch. But this is
barely measurable.
[ran: use bool instead of int for icase, add a recommendation to the
doc, and test a couple "thorny" cases.]

Currently xkb_keymap_num_leds() returns a count of valid (settable)
leds. Because the indexes might be non-consecutive, and some leds
might not be settable, it is incorrect to use this function for
iterating over the leds in the keymap. But this is the main use case of
this function, so instead of the current behavior we adapt the function
to the use case by making it return the needed range of iteration.
The caller needs to handle invalid intermittent indexes, though.

xkb_keymap_num_leds() returns the number of leds that have any
possibility of being set. Even if a led is defined but can not be set in
any way, it is not counted.
In a few places currently we assume that led indexes are smaller than
this number, which is wrong both for the above reason and for the fact
that the xkb format actually allows explicitly setting the indicator
index, which means that the indexes might be non-consecutive.
We don't really have good API to iterate on leds, now, because
xkb_keymap_num_leds is pretty useless. To work around that we use
sizeof(xkb_led_mask_t) * 8.
This makes the "Group 2" led work (try switching to a layout other than
the first in test/interactive).

Our current code (taken from the xserver) doesn't handle unicode keysyms
at all, and there seem to be some other changes compared to libX11,
which is what xkbcomp uses. So we just copy the code that does that from
libX11.
It would be much better to not have to hardcode unicode tables like
that, but it's probably better than dealing with glibc locale stuff for
now. It also doesn't affect our binary size much.

This is a regression introduced in ed78fbcb30.
XKB_STATE_EFFECTIVE is just a OR of the other states, so using & here is
completely wrong. So test/state shows for example:
dumping state for LCtrl down:
group English (US) (0): effective depressed latched locked
mod Control (2): depressed latched locked
dumping state for LCtrl + RAlt down:
group English (US) (0): effective depressed latched locked
mod Control (2): depressed latched locked
mod Mod1 (3): depressed latched locked
dumping state for RAlt down:
group English (US) (0): effective depressed latched locked
mod Mod1 (3): depressed latched locked
dumping state for Caps Lock:
group English (US) (0): effective depressed latched locked
mod Lock (1): depressed latched locked
led Caps Lock (0): active
dumping state for Alt-Shift-+
group English (US) (0): effective depressed latched locked
mod Shift (0): depressed latched locked
mod Mod1 (3): depressed latched locked
which is bogus.

This rule allows you to put several xkb_keymaps in one file.
This doesn't make any sense: only the default/first can ever be used,
yet the others are fully parsed as well.
Different keymaps should just be put in different files.

This is a proof-of-concept for the long key names. The keycodes in the
file evdev-xkbcommon are autogenerated from linux/input.h, and uses the
names given there; all of the previous names are aliased to the new
names, so they continue to work with the symbols files, etc.
You can try it with 'sudo ./test/interactive -r evdev-xkbcommon -n 0'
The -n 0 means that we don't offset the evdev scan codes - just feed
them directly. The -r evdev-xkbcommon just means to use a new rules file
which makes us use the new keycodes file. (The only problem I can see is
with the MENU and LSGT names which has some conflicts).
Maybe some day xkeyboard-config could ship something similar, so that
the 8 offset is unneeded.

This function really needs a format argument, for symmetry with the
keymap creation functions. If we add new formats, we will almost
certainly want to add support for serializing it into a string. It would
also allow to convert from one format to another, etc.
The in the common case, the user would just want to use the format she
used to create the keymap; for that we add a special
XKB_KEYMAP_USE_ORIGINAL_FORMAT value, which will do that (it is defined
to -1 outside of the enum because I have a feeling we might want to use
0 for something else). To support this we need to keep the format inside
the keymap. While we're at it we also initialize keymap flags properly.
This changes the API, but the old xkb_map_get_as_string name works as
expected so this is the best time to do this.

This is to follow the general scheme set by all of the other API
functions.
Since no one is using these functions yet, we don't (actually better
not) add the old names to xkbcommon-compat.h.

These values weren't wrapped before, which caused group_index_is_active
to stop working after a few group switches.
Also, the current group-wrapping function didn't take into consideration
actions such as LockGroup=-1, which need to wrap around, etc.
xkb_layout_index_t is unsigned, but it was used to hold possibly
negative values (e.g. locked_group is 0 and gets a -1 action).
This group wrapping function should now act like the XkbAdjustGroup
function from xserver, and at least ./test/interactive doesn't bring up
any problems with group switching any more.

This old rules parser gives the same kccgst here, so in the interest of
staying compatible we shouldn't fix it there. Similarly we shouldn't
touch ParseIncludeMap, so this is the best place to handle this.

Trying ''./test/interactive -l us:5' causes us to crash.
The <layout>:<N> syntax says to put this layout at the N'th level.
However the code (inherited from xkbcomp) doesn't check that the group
is valid, and then happily indexes keyi->groups with it, which has a
static size of XKB_NUM_GROUPS (the SetExplicitGroup function assumes the
index is valid). So any value a user might put there > 4 makes nice
things happen.

e.g. hhhhhHHHHHHHhhhhhh with shift down and up in the middle.
Unfortunately trying a quick test with test/interactive is not possible
because the evdev soft-repeat stops the repeat when another key is
pressed. So you need real soft-repeat for that.

- Add context.h and move context-related functions from xkb-priv.h to
it.
- Move xkb_context definition back to context.c.
- Add keysym.h and move keysym upper/lower/keypad from xkb-priv.h to it.
- Rename xkb-priv.h to map.h since it only contains keymap-related
definitions and declarations now.
- Remove unnecessary includes and some and some other small cleanups.
