We don't yet have generic parsing support for `<filter-value-list>` or
`<paint>`, so listing them here confuses the new StyleValue parsing code
I'm working on. For now, let's skip `<filter-value-list>` since it's
only used in one pkace which manually parses it, and list the parts of
`<paint>` instead which are taken from here:

This class takes on the duties of CLOCK_MONOTONIC, a time without a
defined reference point that always increases. This informs some
important design decisions about the class API: MonotonicTime cannot be
constructed from external time data, except as a computation based on
other monotonic time, or the current monotonic time. Importantly, there
is no default constructor, since the reference point of monotonic time
is unspecified and therefore without meaning as a default.
The current use of monotonic time (via Duration) includes some potential
problems that may be caught when we move most to all code to
MonotonicTime in the next commit.
The API restrictions have one important relaxation:
Kernel::TimeManagement is allowed to exchange raw time data within
MonotonicTime freely. This is required for the clock-agnostic time
accessors for timeouts and syscalls, as well as creating monotonic time
data from hardware in the first place.
This is a clear sign that they want to use a UnixDateTime instead.
This also adds support for placing durations and date times into SQL
databases via their millisecond offset to UTC.
"Wherever applicable" = most places, actually :^), especially for
networking and filesystem timestamps.
This includes changes to unzip, which uses DOSPackedTime, since that is
changed for the FAT file systems.
This is a generic wrapper for a time instant relative to the unix epoch,
and does not account for leap seconds. It should be used in place of
Duration in most current cases.
This is a trivial change, and since this batch of commits will make a
large-scale rebuild necessary anyways, it seems sensible. The feature is
useful for e.g. building compound constant durations at compile time in
a readable way.
That's what this class really is; in fact that's what the first line of
the comment says it is.
This commit does not rename the main files, since those will contain
other time-related classes in a little bit.
This commit adds a GitHub Workflow to prebuild the dev container file
present at .devcontainer/devcontainer.json. This prebuilt image is
pushed to GitHub Container Registry (ghcr).
An additional devcontainer.json is added consuming that image.
This dev container can be selected in editors that process dev
containers (ie GitHub Codespaces), to speed up time to editor.
This fixes the issue where max margin is used to find offset of
floating box although horizonal margins do not collapse so they need
to be summed instead.
Contrary to the log message that was shown, it is not decidedly a logic
error to detach a thread that has exited. Even in the simple unit tests
we have, it's possibly for the thread to run and exit in between the
time it takes for our call to Thread::start() to complete and
Thread::detach() to run. This is often seen on CI.
This is useful for timing just decoder performance.
(It'd be nice to add a `-t` flag that prints timings for all
the different phases, but for now just disabling writing is
sufficient for me.)
This fixes a plethora of rounding problems on many websites.
In the future, we may want to replace this with fixed-point arithmetic
(bug #18566) for performance (and consistency with other engines),
but in the meantime this makes the web look a bit better. :^)
There's a lot more things that could be converted to doubles, which
would reduce the amount of casting necessary in this patch.
We can do that incrementally, however.
...from "bytes" to "size_in_bytes".
I thought at first that `bytes` meant the variable contained
bytes that the decoder would read from.
Also, this variable is called `sz` (for `size`) in the spec.
No behavior change.
There have been multiple reports of Xcode 14.0 (based on upstream LLVM
14) segfaulting when compiling `LibCore/Process.cpp`. Let's require
Xcode 14.3, which is a known good version based on LLVM 15.
Note that Xcode 14.3 requires macOS Ventura, so users of Monterey or
older are expected to get Homebrew Clang instead.
Homebrew Clang 13 also suffers from the same crash. Although I have not
tested on Linux, the backtrace points to the middle-end, so x86_64 is
also likely to be affected. LLVM 14 was released 14 months ago, so it's
not an unreasonable requirement.
Introduce optimization that determines if one node is preceding,
following, ancestor or descdendant of another node by comparing
ancestors chains of both nodes which is much cheaper than using
Node::is_before() that can walk whole subtree in the worst case.
Since the color interpolation requires two pixels in the horizontal and
vertical direction to work, 1 pixel wide or high bitmaps would cause a
crash when scaling. Fix this by clamping the index into the valid range.
Fixes#16047.
SVG presentation attributes are parsed as CSS values, so we also need to
handle CSS variable expansion when handling them.
This (roughly) matches the behavior of other engines. It's also used on
the web, for example on https://stripe.com/ :^)
Previously, we were comparing the "tty" value from
`/sys/kernel/processes` to the TTY value from
`/var/run/utmp` directly. This caused the "WHAT" column to always show
"N/A", because the former is the TTY pseudo name, while the latter is
the full device name.
