This was causing WindowServer and Taskbar to crash sometimes when the
stars aligned and we tried cutting off a string ending with "..." right
on top of an emoji. :^)
It always felt a bit jarring that tooltips would pop in right away when
you hover over a toolbar button. This patch adds a 700ms delay before
they appear, and a 50ms delay before they disappear.
Once a tooltip is up, moving the cursor between two widgets that both
have tooltips will leave the tooltip on screen without delays.
None of the code using this actually expected the timer to fire right
away, but they would instead call start() on it once they were ready to
accept a timer fire.
Let's make the API behave the way its clients believed it did. :^)
There are three possible selection modes for a GUI::AbstractView.
- NoSelection
- SingleSelection
- MultiSelection
We don't enforce these modes fully yet, this patch mostly adds them in
place of the old "multi select" flag.
A future patch could do some MacOS specific things for
set_volatile/set_nonvolatile. For now, swap out the defined(__linux__)
branches for simple not __serenity__ branches.
Create macros for the byte swap operations one would expect to be in
endian.h or byteswap.h in AK/Endian.h. It's likely a similar/different
change will be needed for BSDs, but there's no github action for those
added to the project yet.
The coarse clocks in time.h are a linux extension that we've adopted.
MacOS and the BSDs don't have it, so we need an alias in a platform
header for Lagom builds.
A good number of contributors use macOS. However, we have a bit of
a tendency of breaking the macOS build without realising it.
Luckily, GitHub Actions does actually supply macOS environments,
so let's use it.
This exploits the comment lines in the text/uri-list specification:
https://tools.ietf.org/rfc/rfc2483.txt (page 11), which might be a bit
hackish, but the specification suggests doing the same for other uses,
so it should be fine.
This is just the syscalls and error handling that was done for each
file in delete_paths.
This will be used to prevent the unneeded construction of vectors
when performing cut operations
Now that fonts know their own weight, we no longer need highlighters to
tell us which font to use. Instead, they can just say "this should be
bold" and we'll find the right font ourselves.
The compose() function is supposed to be fast since it can execute
60 times per second. Let's not do obviously avoidable things like
configuration value lookups in there. :^)
This is mostly based on TextDocument's similar methods, these will
help implement searching within the terminal application.
The support for unicode code points is shaky at best, and should
probably be improved further.
This was mentioned in #4574, and the more I think about it the more it
feels just right - let's move it there! :^)
Having to link LaunchServer against LibGUI explicitly should've been
telling enough...
It's not an error to create a Userspace<T> that points to kernel memory
as the point of Userspace<T> is not to validate the address, but rather
to choose safe overloads that do validation before any data transfer
takes place.
Fixes#4581.
The partitioning code was very outdated, and required a full refactor.
The new subsystem removes duplicated code and uses more AK containers.
The most important change is that all implementations of the
PartitionTable class conform to one interface, which made it possible
to remove unnecessary code in the EBRPartitionTable class.
Finding partitions is now done in the StorageManagement singleton,
instead of doing so in init.cpp.
Also, now we don't try to find partitions on demand - the kernel will
try to detect if a StorageDevice is partitioned, and if so, will check
what is the partition table, which could be MBR, GUID or EBR.
Then, it will create DiskPartitionMetadata object for each partition
that is available in the partition table. This object will be used
by the partition enumeration code to create a DiskPartition with the
correct minor number.
