The CMakeLists.txt for Lagom contains a few libraries and executables
with X86-specific code. By excluding those libraries, Lagom builds
for macOS on Arm as well. The places are marked FIXME to be removed
when the libraries will build for Arm.
This property represents the CSS content size, so let's reduce ambiguity
by using the spec terminology.
We also bring a bunch of related functions along for the ride.
Style updates are lazy since late last year, so the StyleInvalidator is
actually hurting us more than it's helping by running the entire CSS
selector machine on the whole DOM for every attribute change.
Instead, simply mark the entire DOM dirty and let the lazy style update
mechanism run *once* on next event loop iteration.
Instead of making each Layout::Node compute style for itself, we now
compute it in TreeBuilder before even calling create_layout_node().
For non-element DOM nodes, we create the style and layout tree node
in TreeBuilder. This allows us to move create_layout_node() from
DOM::Node to DOM::Element.
Under Debian `e2fsck` is found in `/sbin/` which does not match the
existing "version" the script currently uses (`/usr/sbin/e2fsck`
versus `/sbin/e2fsck`); therefore I added a simple `if` condition to
remedy the situation by verifying whether the original path exists or
not, so I can use the one Debian expects.
Special thanks goes to Tim Flynn a.k.a. `trflynn89` for his valuable
feedback.
ECMA-262 defines \s as:
Return the CharSet containing all characters corresponding to a code
point on the right-hand side of the WhiteSpace or LineTerminator
productions.
The LineTerminator production is simply: U+000A, U+000D, U+2028, or
U+2029. Unfortunately there isn't a Unicode property that covers just
those code points.
The WhiteSpace production is: U+0009, U+000B, U+000C, U+FEFF, or any
code point with the Space_Separator general category.
If the Unicode generators are disabled, this will fall back to ASCII
space code points.
Among other things, this lets you run flaky tests to check if they are
still flaky. :^)
This is done in two ways: It makes should_skip_test() always return
false; and skips reading and generating the skipped-tests lists since
we won't use them.
This partially reverts commit a962ee020a.
When the sticky bit is set, the global bit should basically be ignored
except by external callers who want their own special behavior. For
example, RegExp.prototype [ @@match ] will use the global flag to
accumulate consecutive matches. But on the first failure, the regex
loop should break.
The "at most n bytes" behaviour of strncmp is required for this logic to
work, this was overlooked in 5b64abe when converting Strings to
StringViews, which lead to broken autocomplete.
Since the spec does not fully define the entry points of modules what
this means is kind of unclear. But it does work in most cases and can
be useful. We do print out a warning just to clarify why there could be
strange things.
It seems the stack search does not find all functions because they are
kept in variants and other structs. This meant some function could be
cleaned up while we were evaluating a class meaning it would fail/crash
when attempting to run the functions.
This feature had bitrotted somewhat and would trigger errors because
PrimitiveStrings were "destroyed" but because of this mode they were not
removed from the string cache. Even fixing that case running test-js
with the options still failed in more places.
This statement (for now) outputs the name and types of the different
attributes in a table. It's not standard SQL but all DBMSs that I know
of implement a sort of statement for such functionality.
Since the output of DESCRIBE TABLE is just a relation, an internal
schema, `master` was created and a table definition for DESCRIBE into
it. The table definition and the master schema are not accessible by the
user.
LibRegex already implements this loop in a more performant way, so all
LibJS has to do here is to return things in the right shape, and not
loop over the input string.
Previously this was a quadratic operation on string length, which lead
to crazy execution times on failing regexps - now it's nice and fast :^)
Note that a Regex test has to be updated to remove the stateful flag as
it repeats matching on multiple strings.
When GraphicsManagement initializes the drivers we can disable the
bootloader framebuffer console. Right now we don't yet fully destroy
the no longer needed console as it may be in use by another CPU.
Instead of seeing a black screen until GraphicsManagement was fully
initialized, this allows us to see the console output much earlier.
So, if the bootloader provided us with a framebuffer, set up a console
as early as possible.
The GenericFramebufferConsoleImpl class implements the logic without
taking into account any other details such as synchronization. The
GenericFramebufferConsole class then is a simple wrapper around
GenericFramebufferConsoleImpl that takes care of synchronization.
This allows us to re-use this implementation with e.g. different
synchronization schemes.
