The threading tests currently wait for a very small amount of time for
the expected test condition to be reached, e.g. 20ms. This changes the
tests to *check* the condition every 20ms, but allow the test to run for
up to 2s until the condition is reached. This should hopefully resolve
the failures seen on CI.
This also renames one of the tests to match what it actually does. The
test itself was changed in commit 5b335e7, but the name was not updated
to reflect that change.
This attribute is used for functions in the kernel that are entirely
written in assembly, yet defined in C++ source files.
Without `__attribute__((naked))`, Clang might decide to inline these
functions, making any `ret` instructions within them actually exit the
caller, or discard argument values as they appear "dead". This issue
caused a kernel panic when using the `execve` syscall in AArch64
SerenityOS built by Clang.
While the empty definition so far appears to work fine with GCC, simpler
test cases do similarly suffer from unintended inlining, so define
`NAKED` as a synonym of `NEVER_INLINE` to avert future issues.
Perhaps we should move users of `NAKED` to plain assembly files?
This makes aarch64Clang builds boot :^)
The spice server will ignore any clipboard-related messages if we don't
have the appropriate capabilities, but I think it's better for us to
do less CPU churning whenever the user copies something to their
clipboard.
It also stops the spice server from warning in the console
about a clipboard grab message being recieved when the capability was
never announced.
If we finish parsing a calculation tree and it still contains
UnparsedCalculationNodes, then it's not valid, and we shouldn't create
a StyleValue from it.
This avoids a ton of work when painting large documents. Even though it
would eventually get clipped by the painter anyway, by bailing out
earlier, we avoid a lot more work (UTF-8 iteration, OpenType lookups,
etc).
It would be even nicer if we could skip entire line boxes, but we don't
have a fast way to get the bounding rect of a line box at the moment.
Some of the live HTMLCollection only ever contain children of their root
node. When we know that's the case, we can avoid doing a full subtree
traversal of all descendants and only visit children.
This cuts the ECMA262 spec loading time by over 10 seconds. :^)
In addition, this renames the internal timer to better suit its new
purpose since the playback state handlers were added. Not only is it
used to time frame presentations, but also to poll the queue when
seeking or buffering.
Running decoding on the main thread can cause frames to be delayed due
to the presentation timer waiting for a decode to finish. If a frame
takes too long to decode, this delay can be quite visible. Therefore,
decoding has been moved to a separate thread, with frames sent to the
main thread through a thread-safe queue.
This results in frame times going from being late by up to 16ms to a
very consistent ~1-2ms.
Previously, calling `.right()` on a `Gfx::Rect` would return the last
column's coordinate still inside the rectangle, or `left + width - 1`.
This is called 'endpoint inclusive' and does not make a lot of sense for
`Gfx::Rect<float>` where a rectangle of width 5 at position (0, 0) would
return 4 as its right side. This same problem exists for `.bottom()`.
This changes `Gfx::Rect` to be endpoint exclusive, which gives us the
nice property that `width = right - left` and `height = bottom - top`.
It enables us to treat `Gfx::Rect<int>` and `Gfx::Rect<float>` exactly
the same.
All users of `Gfx::Rect` have been updated accordingly.
Previously, the engine would attempt to make a move if the engine was
changed after the game had ended.
This change also allows the player to always flip the board when the
game is finished, instead of only being able to flip the board on
their turn.
Before this change, LayoutState essentially had a Vector<UsedValues*>
resized to the exact number of layout nodes in the current document.
When a nested layout is performed (to calculate the intrinsic size of
something), we make a new LayoutState with its own Vector. If an entry
is missing in a nested LayoutState, we check the parent chain all the
way up to the root.
Because each nested LayoutState had to allocate a new Vector with space
for all layout nodes, this could get really nasty on very large pages
(such as the ECMA262 specification).
This patch replaces the Vector with a HashMap. There's now a small cost
to lookups, but what we get in return is the ability to handle huge
layout trees without spending eternity in page faults.
By deferring allocation of StaticNodeList objects until we know somebody
actually wants the MutationRecord, we avoid a *lot* of allocation work.
This shaves several seconds off of loading https://tc39.es/ecma262/
At least one other engine (WebKit) skips creating mutation records if
nobody is interested, so even if this is observable somehow, we would
at least match the behavior of a major engine.
Before this, any style change that mutated a property we consider
"layout-affecting" would trigger a complete teardown and rebuild of the
layout tree.
This isn't actually necessary for the vast majority of CSS properties,
so this patch makes the invalidation a bit finer, and we now only
rebuild the layout tree when the CSS display property changes.
For other layout-affecting properties, we keep the old layout tree (if
we have one) and run the layout algorithms over that once again.
This is significantly faster, since we don't have to run all the CSS
selectors all over again.
Currently, an error message box appears when a user tries to cancel
the editor dialog while editing or adding a bookmark.
This snapshot resolves this by having `add_bookmark()` and
`BookmarksBarWidget::edit_bookmark()` perform an if check on the
result of `BookmarkEditor::edit_bookmark()` to see if the dialog
was canceled.
Corrects a slew of titles, buttons, labels, menu items and status bars
for capitalization, ellipses and punctuation.
Rewords a few actions and dialogs to use uniform language and
punctuation.
Pixels will leave the lossy decoder with alpha set to 255.
The old code would be a no-op in that case.
No observable behavior change yet, since there still is no
decoder for lossy webp.
Rather than queueing microtasks ad nauseam to check if a media element
has a new source candidate, let the media element tell us when it might
have a new child to inspect. This removes endless CPU churn in cases
where there is never a candidate that we can play.
This fixes a crash in box_baseline, due to cells created for
display: table expecting a box child and getting the inline node wrapper
instead.
Fixes#18972.
Core::System::mkfifo() doesn't rely on POSIX's mkfifo() and sends the
syscall directly to our system. This means that the and errno doesn't
get updated which ultimately caused the program to display an incorrect
message 'mkfifo: Success (not an error)'.
This now allows websites such as Discord, YouTube and your favourite
"Right Click" xkcd comic to open a custom context menu when you right
click. You can bypass this by holding shift, just like Firefox.
