Double ampersands (&&) marking in menus is meant to provide a way
to show the ampersand, since using just one would turn it
into a modifier that sets the shortcut for the next character.
Unfortunately, while the first character had a special case to avoid
marking this set, the marking was still calculated
for the second character.
The fix is rather simple: just skip then the following character!
This issue applied only to the visual part of the Menu.
The WindowServer calculation for the shortcut character is working
properly, i.e. ignores escaped ampersands.
If the text-for-rendering of the last selected node is empty, the select
all implementation would end up setting the index to -1. This value is
used directly for a substring length in the copy text implementation,
thus would cause a failed assertion.
In case we are about to delete the PID directory, we clear the Process
pointer. If someone still holds a reference to the PID directory (by
opening it), we still need to delete the process, but we can't delete
the directory, so we will keep it alive, but any operation on it will
fail by propogating the error to userspace about that the Process was
deleted and therefore there's no meaning to trying to do operations on
the directory.
Fixes#8576.
Before this change PNGWriter::add_chunk used to make a copy of
PNGChunk's ByteBuffer to prepend the size of the data.
With this change, 4-byte space is saved from the beginning and written
at the end of the operation. Avoiding this copy yields significant
speed up.
Rather than parsing the selector every time we want to check it, we
now parse it once at the beginning.
A bonus effect of this is that we now support a selector list in
:not(), instead of just a single selector, though only when using
the new parser.
The end goal is to make the PseudoClass::not_selector be a Selector
instead of a String that is repeatedly re-parsed. But since Selector
contains a Vector of ComplexSelectors, which each have a Vector of
SimpleSelectors, it's probably a good idea to not be passing them
around by value anyway. :^)
Same reasoning again! This is the last one.
While I was at it, I added the two remaining CSS2.2 pseudo-elements,
::first-line and ::first-letter. All 4 are handled in the new CSS
parser, including with the compatibility single-colon syntax. I have
not added support to the old parser.
Previously, SimpleSelectors optionally had Attribute-selector data
as well as their main type. Now, they're either one or the other,
which better matches the spec, and makes parsing and matching more
straightforward.
Since Clang enables a couple of warnings that we don't have in GCC,
these were not caught before. Included fixes:
- Use correct printf format string for `size_t`
- Don't compare Nonnull(Ref|Own)Ptr` to nullptr
- Fix unsigned int& => unsigned long& conversion
We have had these for quite a while, but we didn't compile them, and
used GCC's version instead. Clang does not come with these, so we have
to provide our own implementation.
Our implementation follows what `musl` and `FreeBSD` do, so this should
work fine, even if documentation can hardly be found for them.
The GCC documentation says that since it's officially a part of C++20,
this flag does nothing. Clang, however, does complain that it does not
recognize it, so it's better to just remove it.
This code worked with GCC because libstdc++ pulls in `type_info`'s
definition through the `cxxabi` header included by `AK/Demangle.h`.
In contrast, `libc++` only forward-declares it, so this code failed to
compile with it.
The C++ standard says that it's legal to call the `delete` operator with
a null pointer argument, in which case it should be a no-op. I
encountered this issue when running a kernel that's compiled with Clang.
I assume this fact was used for some kind of optimization.
If QEMU has the qemu_vdagent chardev (should be present in QEMU 6.1)
then we use that as the SPICE client.
If qemu_vdagent is not present, no SPICE client will be launched by
default because it makes the display a bit choppy.
Set SERENITY_SPICE to override the default behavior and use your default
SPICE client.
A SPICE agent communicates with the host OS to provide nifty features
like clipboard sharing :^)
This patch implements only plain-text clipboard sharing.

It's possible that another thread might try to exit the process just
about the same time another thread does the same, or a crash happens.
Also, we may not be able to kill all other threads instantly as they
may be blocked in the kernel (though in this case they would get killed
before ever returning back to user mode. So keep track of whether
Process::die was already called and ignore it on subsequent calls.
Fixes#8485
This will generate absolute paths lexically rather than through a call
to realpath. The motivation for this is to generate absolute paths for
non-existent files in unveil calls, as realpath will not work if the
file does not exist.
We have a new config argument to add space separated exclude regex'
This is separate from "NotTestsPattern", because these are still Tests,
although they are not supposed to be run by the runner
This also adds the test for a working UserspaceEmulator to the tests run
