As mentioned in 2d39da5 the usual pattern is that LibFoo provides a Foo
namespace - LibCoreDump doesn't, so this renames CoreDumpReader to
Reader and puts it in the CoreDump namespace. :^)
I ran into this exact but at least twenty times in Serenity alone. The
C++ Standard dictates that 'unsigned long' and 'unsigned long long' are
distinct types even though on most platforms they are usually both 64
bit integers.
Also it wasn't possible to evaluate IsIntegral<T> for types that were
not integers since it used MakeUnsigned<T> internally.
We now map most shared library text segments shared, read+exec only.
This reduces our memory footprint at system startup by 16 MB which is
pretty neat! :^)
Anything above or equal to the 2 GB mark has the left most bit set
(0x8000...), which was falsely interpreted as negative due to
local_offset being signed.
This makes it unsigned by using FlatPtr. To check for underflow as
was intended, lets use Checked instead.
Fixes#4585
If the user is typing in the cell editor and has the cursor in a
function call, try to show a tip for the arguments of that function:
(cursor denoted by `|`)
```
sum(|
```
should show:
```
sum(cell names)
```
in a tooltip-like window below the editor.
We were painting unfinished pixels while waiting for the WebContent
process to render the page. This caused OOPWV to flicker black
sometimes, which looked pretty bad.
This way we still flicker, but at least we flicker with the correct
palette color. :^)
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.
