We can now recognize & normalize all time zones from the IANA time zone
database and not just 'UTC', which makes the LibJS Temporal
implementation a lot more useful! Thanks to the newly added LibTimeZone,
this was incredibly easy to implement :^)
This already includes these recent editorial changes in the Temporal
spec: 27bffe1
Instead of only having dummy functions that don't work with any input,
let's at least support one time zone: 'UTC'. This matches the basic
Temporal implementation for engines without ECMA-262, for example.
Previously parse_time_zone_numeric_utc_offset_syntax() would return true
to indicate success when parsing a string with an invalid number of
digits in the fractional seconds part (e.g. 23:59:59.9999999999).
We need to check if the lexer has any characters remaining, and return
false if that's the case.
This commit extracts out the GUI initialization in AudioWidget into
the new try_initialize_graphical_elements function. This function
is now able to use try_set_main_widget instead of set_main_widget.
It's only called by the fallible try_create method.
This helper that originally appeared in 4.4BSD helps to daemonize
a process by forking, setting itself as session leader, chdir to "/" and
closing stdin/stdout.
This is a rather naive implementation, but serves as a first pass at
determining the GMT offset for a time zone at a particular point in
time. This implementation ignores DST (because we are not parsing any
RULE entries yet), and ignores any offset patterns of the form "Mon>4"
or "lastSun".
This CMakeLists.txt was basically copy-pasted from LibUnicode, where the
generated data is separated into its own library. This was to let other
libraries / applications decide if they actually want to link the data
because it is so large. LibTimeZone's generated data is significantly
smaller, so this separation really isn't needed.
The special URL links (help://man) and the application opening links now
work on the man page website. While the page links are translated
correctly, the application launch can't be implemented. For this reason,
an explanatory error page is shown instead.
The URLs of the form `help://man/<section>/<page>` link to another help
page inside the help application. All previous relative page links are
replaced by this new form. This doesn't change any behavior but it looks
much nicer :^)
Note that man doesn't handle these new links, but the previous relative
links didn't work either.
Link handling is now split up between open_page and open_url. While
open_page can handle any sort of input and is responsible for handling
history UI, open_url deals in URLs and takes one of a few different
actions depending on the exact URL given. Currently, only file:// URLs
are handled but this will change in the next few commits.
Note that this commit breaks relative URLs on purpose. After the new
help:// URLs, they won't be needed anyways. The reasoning is that many
URLs not specifically pointing to man page directories will cause a
(non-deadly) unveil violation in `real_path_for`. This specifically
concerns the new application launch URLs that are added in the next
commit.
Previously when the delete key was pressed, only the first selected
cell index would have been deleted. This commit remedies that by first
checking when more than a single index is selected.
NoAllocationGuard is an RAII stack guard that prevents allocations
while it exists. This is done through a thread-local global flag which
causes malloc to crash on a VERIFY if it is false. The guard allows for
recursion.
The intended use case for this class is in real-time audio code. In such
code, allocations are really bad, and this is an easy way of dynamically
enforcing the no-allocations rule while giving the user good feedback if
it is violated. Before real-time audio code is executed, e.g. in LibDSP,
a NoAllocationGuard is instantiated. This is not done with this commit,
as currently some code in LibDSP may still incorrectly allocate in real-
time situations.
Other use cases for the Kernel have also been added, so this commit
builds on the previous to add the support both in Userland and in the
Kernel.
This is a normative change to the Intl spec:
20e5c26
Note that this doesn't actually affect us. Its purpose is to provide the
hour-cycle to BestFitFormatMatcher. This AO is implementation defined,
and ours just invokes BasicFormatMatcher, which doesn't use this field.
We could now have LibUnicode generate this field and use it to find a
better format pattern, though.
Previously, upon reaching the target, the player is presented with
potentially two dialog boxes: one asking if the user wants to
continue endlessly and another showing the player's statistics,
which would only be shown if the user does not want to continue.
This commit consolidates these into a single dialog box that shows
the relevant statistics and asks the user if they want to continue
endlessly.
When opening 2048's settings, it translates the target tile into
a power of 2. Previously, it was done incorrectly, causing the
resulting value to be off by one, and the number would increase
every time one opens, saves and closes the settings. With this
change, it now works as expected.
Context parameters are LibGL's way of centrally defining all parameters
that can be retrieved through `glGetBoolean*`, `glGetInteger*`, etc.
The spec describes that capabilities such as `GL_LIGHTING` can also be
retrieved through these methods, but it should not be possible to
retrieve random boolean parameters through `glIsEnabled`. For example,
`GL_UNPACK_LSB_FIRST` can only be retrieved through `glGet*`.
This moves reading of capabilities to `::get_context_parameter` and
implements its use in `::gl_is_enabled`.
Instead of using plain objects as Iterator records, causes confusion
about the object itself actually being its [[Iterator]] slot, and
requires non-standard type conversion shenanigans fpr the [[NextValue]]
and [[Done]] internal slots, implement a proper Iterator record struct
and use it throughout.
Also annotate the remaining Iterator AOs with spec comments while we're
here.
Change the parent of the WizardDialog to that of the Spreadsheet window.
Previously the WizardDialog was using the open file dialog as the
parent resulting in the csv import dialog
Using a WeakPtr to keep a reference to the active layer caused it to
be destroyed when the last tab was closed, which made the
m_layer == layer check in set_layer() return early since it was
already null. Because of this the LayerPropertiesWidget was never
disabled.
After closing the last open ImageEditor, selecting a color would try to
dereference it causing a crash. Instead make set_image_editor() take a
pointer to it and set it to nullptr when closing the last tab like we
do with LayerListWidget and LayerPropertiesWidget.
The name `scissor_box_to_window_coordinates` was wildy inaccurate since
we are actually transforming window coordinates into whatever the
coordinate space of the backing bitmap is.
Previously the scroll position would not reset when loading a new
page. This caused various problems such as opening the page at the
previous pages scroll position and in some instances not even
showing the new page at all.
This adds a half pixel offset to the edge value calculation in order to
sample the triangle at pixel centers. This is in line with actual OpenGL
rasterization rules and generates correctly interpolated vertex
attributes including texture coordinates.
With the RASTERIZER_BLOCK_SIZE gone we can now render to any size, even
odd ones. We have to be careful to not generate out of bounds accesses
when calculating the render target and depth buffer pointers. Thus we
check the coverage mask and generate nullptrs for pixels that will not
be updated. This also masks out pixels that would touch the triangle but
are outside the render target/scissor rect bounds.
