Matching keyboard shortcuts on internationalized keyboards is actually
non-trivial. Matching the actual key is easy, but the modifiers can be
used by both, the matching and the translation step. Therefore, XKB
exports "consumed-modifiers" that we use to figure out whether a modifier
was already used by the translation step.
The new IDEV_KBDMATCH() helper can be used to match on any keyboard
shortcut and it will do the right thing.
Implement the feed_keyboard() handling by mapping XKB keys according to
DEC-VT behavior.
Public information on terminal key-mappings is pretty scarce. We only
implement the most basic mapping for now. Further improvements welcome!
In case we cannot render a glyph, we want a fallback we can display
instead. If we rely on the font itself to provide the fallback character,
we have nothing to display if that character is not available. Therefore,
add a static fallback that we can use at any time.
If a pipe is enabled/disabled, we have to clear crtc->applied of the
linked CRTC. Otherwise, we will not run a deep modeset, but leave the crtc
in the pre-configured state.
We really want more sophisticated aging than just 64bit integers. So
always provide front *and* back buffers to renderers so they can compare
arbitrary aging information and decide whether to re-render.
Instead of looking for available back-buffers on each operation, set it to
NULL and wait for the next frame request. It will call back into the pipe
to request the back-buffer via ->target(), where we can do the same and
look for an available backbuffer.
This simplifies the code and avoids double lookups if we run short of
buffers.
Coverity complained about this code and is partially right. We are not
really protected against integer overflows. Sure, unlikely, but lets just
avoid any overflows and properly protect our parser loop.
Lets return the parsed length in term_utf8_decode() instead of a buffer
pointer. Store the pointer in the passed argument.
This makes it adhere to the systemd coding-style, were we always avoid
returning pointers, but store them in output arguments. In this case, the
storage is not allocated, so it doesn't fit 100% to this idiom, but still
looks much nicer.
We currently select front-buffers as new back-buffer if they happen to be
the last buffer in our framebuffer-array. Fix this by never selecting a
new front buffer as back buffer.
Spotted with coverity. If parsing both /etc/os-release and
/usr/lib/os-release fails then null would be passed on. The calls
to parse the two files are allowed to fail. A empty /etc may not
have had the /etc/os-release symlink restored yet and we just
try again in the loop. If for whatever reason that does not happen
then we now pass on 'n/a' instead of null.
Coverity seems to think that we can later end up with the "them"
fd having a negative value. Even after a succesful barrier_create.
Add some test to verify that the constructor went well. If coverity
still complains then it must mean that it thinks the the value is
overwritten later.
Example from Tom Gundersen is included using xi:include.
The copyright notice stands out a bit. Maybe it should be removed,
and the code placed in public domain.
The caller may have an existing DUID that it wants to use, and may
want to use some other DUID generation scheme than systemd's
default DUID-EN.

This patch adds a transient user unit directory under
`$XDG_RUNTIME_DIR/systemd/user/` and stores transient user-instance
units (such as those created by `systemd-run --user`) under there
instead of putting them in $XDG_CONFIG_HOME/systemd/user/.

We cannot rely on "errno" to be non-zero on failure, if we perform
multiple glibc calls. That is, if the first eventfd() call fails, but the
second succeeds, we cleanup the barrier but return 0.
Fix this by always testing the return value immediately. This should also
fix all the coverity warnings.
All the definitions are for outside users, so drop the -internal suffix.
Internal definitions are in unifont-def.h and unifont.c, no need to share
those.
D-Bus' type hierarchy as described in the spec is:
\- basic
\- fixed type (u, i, etc.)
\- string-like type (s, o, g)
\- container
Someone seems to have referred to basic types as "simple types" at
some point, but that term isn't defined in the D-Bus Specification,
and seems redundant.
So far I haven't renamed functions that use "trivial" in their names
to mean "fixed type", to avoid confusion about whether a struct of
constant length, like (iu), is a fixed type. The answer is that it is
fixed-length, but is not a "fixed type", so I can see that something
like bus_type_is_fixed() might be ambiguous.
