- Clamp the checkerboard scanline prologue length to the total width
of the (clipped) rect we're filling.
- Use fast_u32_fill() for the prologue and epilogue as well.
Let's give ourselves the tools needed to update less than the entire
image every time we paint.
This patch adds plumbing so that Layer invalidations have a modified
rect that gets passed on to Image, and then on to ImageEditor.
LibGUI widgets fully contain their child widgets, so there's no pass
the paint event on to our children if we get a paint event that doesn't
intersect with our rect.
While Gfx::Painter was already dutifully clipping out any attempts at
painting, this avoids even more pointless work.
It's perfectly acceptable for the segment's vaddr to not be page aligned
as long as the segment itself is page-aligned. We'll just map a few more
bytes at the start of the segment that will be unused by the library.
We didn't notice this problem because because GCC either always uses
0 for the .text segment's vaddr or at least aligns the vaddr to the
page size.
LibELF would also fail to load really small libraries (i.e. smaller than
4096 bytes).
Using LibELF to do the initial relocations doesn't work when building
SerenityOS with Clang. We seem to be accessing a global symbol that
hasn't been relocated yet somewhere along the path to
ELF::DynamicObject::create().
There is a race condition where we would remove a FutexQueue from
our futex map and in the meanwhile another thread started to queue
itself into that very same futex, leading to that thread to wait
forever as no other wake operation could discover that removed
FutexQueue.
This fixes the problem by:
* Tracking imminent waits, which prevents a new FutexQueue from being
deleted that a thread will wait on momentarily
* Atomically marking a FutexQueue as removed, which prevents a thread
from waiting on it before it is actually removed from the futex map.
Here we got our first Temporal object :^)
This patch adds the TimeZone object itself, its constructor and
prototype (currently empty), and a bunch of required abstract operations
Add a JS_ENUMERATE_TEMPORAL_OBJECTS macro and use it to generate:
- Forward declarations
- CommonPropertyNames class name members
- Constructor and prototype GlobalObject members, getters, visitors,
and initialize_constructor() calls
This will be home to various functions:
- Temporal.now.timeZone()
- Temporal.now.instant()
- Temporal.now.plainDateTime()
- Temporal.now.plainDateTimeISO()
- Temporal.now.zonedDateTime()
- Temporal.now.zonedDateTimeISO()
- Temporal.now.plainDate()
- Temporal.now.plainDateISO()
- Temporal.now.plainTimeISO()
Currently empty, but we gotta start somewhere! This is the start of
implementing the Temporal proposal (currently stage 3).
I have decided to start a new subdirectory (Runtime/Temporal/) as well
as a new C++ namespace (JS::Temporal) for this so we don't have to
prefix all the files and classes with "Temporal" - there will be a lot.

This only causes 1 new test262 test to pass. Other tests that rely on
this coercion fail due to receiving an unexpected value for 'this' when
invoking a functional replacement. For example:
String/prototype/replaceAll/replaceValue-call-matching-empty.js
Receives 'undefined' for 'this' in the functional replacement invocation
but is expected to receive the global 'this'.
The String.prototype.replace spec requires evaluating the replacement
value (if it is not a function) before searching the source string.
Fixes 4 test262 tests.
This adds a utility program which is essentially a command generator for
CMake. It reads the 'components.ini' file generated by CMake in the
build directory, prompts the user to select a build type and optionally
customize it, generates and runs a CMake command as well as 'ninja
clean' and 'rm -rf Root', which are needed to properly remove system
components.
The program uses whiptail(1) for user interaction.
10.4.2 Array Exotic Objects
https://tc39.es/ecma262/#sec-array-exotic-objects
A String property name P is an array index if and only if
ToString(ToUint32(P)) equals P and ToUint32(P) is not the same value
as 𝔽(2^32 - 1).
It would be enough to use relaxed ordering here if it weren't for
the mutex, which we also need to store and retrieve. To ensure the
pthread_cond_broadcast() call sees the store, use release and acquire
as appropriate. Thankfully, both of these are on the slow paths.
Now that the test is converted to be LibTest based, we can remove it
from the exclude list in /home/anon/.config/Tests.ini.
Prior to this it would crash and fail because it was signaled instead of
returning normally with exit code 0.
The actual data file for this benchmark was never actually committed to
the repository, so let's generate 100k identical lines in memory to be
the fairly large data for this test instead.
Because these processes are expected to crash, generating a core dump
from them and throwing up a CrashReporter window is less helpful than
it is distracting while running many tests at a time.
Use the prctl for controlling the core dump-able flag to tell the kernel
we don't want core dumps from these processes. Note that because we also
build LibTest for Lagom, we have to check for MacOS which doesn't
support prctl(PR_SET_DUMPABLE).
After the changes to LibGfx to make default font management handled in
WindowServer instead of each GUI application to allow for global font
broadcasts, the two LibGfx tests broke. The non-benchmark was fixed in
8f96d2, but the benchmark was left in the dust because nobody really
runs it manually :^(
We pass this to test-js, and since they share some common code, it makes
sense to pass it to run-tests as well. This prevents the OSC 9 escape
sequences from being emitted when running tests via the script.
