The REPL does not have a reliable way to tell us the UTF-8 byte count of
the source string, so we must use strlen() ourselves.
|
|
This is still not perfect, as we now actually crash in the
`try-finally-continue` tests, while we now succeed all
`try-catch-finally-*` tests.
Note that we do not yet go through the finally block when exiting the
unwind context through a break or continue.
|
|
We are already doing this in a good manner via the generated code,
doing so in the execution loop as well will cause us to pop contexts
multiple times, which is not very good.
|
|
This is essentially a LeaveUnwind+Jump, so lets just do that, that will
make it easier to optimize it, or see unwind state transitions
|
|
Before we were doing so while exiting the catch-block, but not when
exiting the try-block.
This now centralizes the responsibility to exit the unwind context to
the finalizer, ignoring return/break/continue.
This makes it easier to handle the return case in a future commit.
|
|
Previously we allowed the end_offset to be larger than the chunk itself,
which made it so that certain input sizes would make the logic attempt
to delete a nonexistent object.
Fixes #16308.

This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.
One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.
|
|
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)

Currently placing floating blocks in anonymous nodes makes
https://stackoverflow.com/ hang so let's leave it to try
to place only absolute blocks in anonymous nodes for now.
Also it breaks flex formatting when element with floating is
flex child.

The runtime environment of the WASM REPL does not have time zone
information; the file system is virtual (does not have /etc/localtime),
and the TZ environment variable is not set. This causes LibTimeZone to
always fall back to UTC.
Instead, we can get the time zone from the user's browser before we
enter this limited environment. The REPL website will pass the time zone
into the WASM REPL.
|
|
Without this, we were in a weird state where LibTimeZone believed it had
TZDB data, but that data wasn't actually available to it. This caused
functions like JS::get_named_time_zone_offset_nanoseconds() to trip an
assertion when entering "new Date();" into the REPL.
|
|
This doesn't have any immediate uses, but this adapts the code a bit
more to `Core::Stream` conventions (as most functions there use
NonnullOwnPtr to handle streams) and it makes it a bit clearer that this
pointer isn't actually supposed to be null. In fact, MP3LoaderPlugin
and FlacLoaderPlugin apparently forgot to check for that completely
before starting to decode data.
|
|
This now prepares all the needed (fallible) components before actually
constructing a LoaderPlugin object, so we are no longer filling them in
at an arbitrary later point in time.
|
|
`Bytes` is very slim, so the memory and/or performance gains from
passing it by reference isn't that big, and it passing it by value is
more compatible with xvalues, which is handy for things like
`::try_create(buffer.bytes())`.

This fixes a rendering issue where box-shadows would not appear or
render completely broken if the blur radius was larger than the
border radius (border-radius < 2 * blur-radius to be exact).

Here I try to address bug where content of table overflows
it's width (hacker news is an example of such site) by
reimplementing some parts of table formatting context.
Now TFC implements first steps of:
https://www.w3.org/TR/css-tables-3/#table-layout-algorithm
but column width and row height distribution steps are
still very incomplete.

Fixes a small typo where the word `are` was missing.

This patch adds a way to ask the allocator to skip its internal
scrubbing memset operation. Before this change, kcalloc() would scrub
twice: once internally in kmalloc() and then again in kcalloc().
The same mechanism already existed in LibC malloc, and this patch
brings it over to the kernel heap allocator as well.
This solves one FIXME in kcalloc(). :^)

Add fonts Hantschrift and Schwedische Schreibschrift

Also commonly referred to as "reverse scrolling" or "inverted
scrolling".

Also, we add a section that describes how to get an updated clang-format
with multiple possible options to do that.

This is required to load libsoftgpu for the WebGL demos.

This order seems more natural as it is used in basically all apps on
other systems (e.g. Firefox, CLion,...).
|
|
Changing the naming conventions one-by-one was tedious and error-prone.
A settings file is likely to be more forward compatible than a
screenshot. The settings file was made by repeating the manual steps
provided in the documentation, and exporting the file in CLion.

The two major changes noticeable on the SerenityOS codebase are:
- Much improved support for const placement, clang-format-14 ignored
our east-const configuration in various places
- Different formatting for requires clauses, now breaking them onto
their own line, which helps with readability a bit
Current versions of CLion also ship LLVM 15, so the built-in formatting
now matches CI formatting again :^)

Same as 42865b8975818116b922aa2411eb167618fc532c.

Follow the same pattern as the other Qt ports to use qmake to determine
the location of host binaries and libraries.
|
|
While we're here, make the host path detection more portable.
|
|
Qt 6.4.0 relies on the definitions of ELFOSABI_GNU, ELFOSABI_AIX, and
EM_S390 existing.

This makes the port install drop the CMake install files into the
sysroot, which is friendlier to macOS users. Homebrew CMake really
likes to pick homebrew zstd, even for cross-builds.

As Evil stated in the Discord, WSL users must install the DLL
libraries with their QEMU Installation or else they will receive
obscure errors about the syntax of the Meta/run.sh file as shown in
SerenityOS#14033.

Before these tests could be flaky if they happened to be called around
the edge of a second. Now we try up to 5 times to execute the tests
while staying within the same second.

The hostent struct's h_aliases field conventionally contains a pointer
to an array of alternate hostnames, where the final entry in this array
is a nullptr (signifying the end of the list).
At least one POSIX application (Pine email client) does not expect
`h_aliases` itself to be nullptr.

This solves one of the security issues being mentioned in issue #15996.
We simply don't allow creating hardlinks on paths that were not unveiled
as writable to prevent possible bypass on a certain path that was
unveiled as non-writable.
