Our "frame" concept very closely matches what the web specs call a
"browsing context", so let's rename it to that. :^)
The "main frame" becomes the "top-level browsing context",
and "sub-frames" are now "nested browsing contexts".
The index of the tree column will not change while painting.
Neither will the number of columsn. So avoid a whole bunch of virtual
function calls by caching these two values at the start of painting.
Textures are now initialized with a nullptr upon generation.
They are only actually created once they are bound to a target.
Currently only the GL_TEXTURE_2D target is supported.
The software rasterizer now allows rendering with or without
a bound TEXTURE_2D.
With the increased volume of PRs being opened and merged lately,
multiple people have complained that the IRC is absolutely flooded with
SerenityBot posts. Remove the IRC notifications from the CI scripts, and
the Meta script that handles parsing the github actions context into
an IRC message.
This adds an implementation for the Home, End, Page Up and Page Down
cursor movements for TreeView.
Also, the Up and Down movement implementations are replaced by a more
efficient traversal mechanism: whereas the old code would walk over all
visible nodes every time, the new code only evaluates relevant sibling
and parent indices.
When LibC/shadow.cpp parses shadow entries in getspent, it sets the
spwd member value to disabled (-1) if the value is empty. When
Core::Account::sync calls getspent to generate a new shadow file, it
would recieve the -1 values and write them in the shadow file. This
would cause the /etc/shadow file to be cluttered with disabled values
after any password change.
This patch checks if the spwd member value is disabled, and prints the
appropriate value to the shadow file.
Bitmap files use negative height values to signify that the image
should be rendered top down, but if the height value equals to the
minimum value, negating it to get the actual height results in UB.
Github Actions added clang-12 to their ubuntu 20.04 images, so let's
take full advantage of that. Stop relying on the llvm upstream
repository for clang-12, since it often causes jobs to fail when
their mirrors are syncing.
clang-tidy-11, libstdc++-10-dev and npm 6.14.x are also all already
pre-installed, so we don't need to waste time fetching them in the
dependency fetch step.
Mark the entirety of a heap block's storage poisoned at construction.
Unpoison all of a Cell's memory before allocating it, and re-poison as
much as possible on deallocation. Unfortunately, the entirety of the
FreelistEntry must be kept unpoisoned in order for reallocation to work
correctly.
Decreasing the size of FreelistEntry or adding a larger redzone to Cells
would make the instrumentation even better.
Use this to avoid creating a 16 byte cell allocator on x86_64, where the
size of FreelistEntry is 24 bytes. Every JS::Cell must be at least the
size of the FreelistEntry or things start crashing, so the 16 byte
allocator was wasted on that platform.
This adds two new arguments to the thread_exit system call which let
a thread unmap an arbitrary VM range on thread exit. LibPthread
uses this functionality to unmap the thread stack.
Fixes#7267.
This change allows the controller to utilize interrupts even if no
device was connected to a port when we initialize it, so we can support
hotplug events now.
This was proved to be a problematic option. I tested this option on
bare metal AHCI controller, and if we didn't reset the controller, the
firmware (SeaBIOS) could leave the controller state not clean, so an
plugged device signature was in place although the specific port had no
plugged device after rebooting.
Therefore, we need to ensure we use the controller in a clean state
always.
In addition to that, the Complete option was renamed to Aggressive, as
it represents better the consequences of choosing this option.
