If there are no search results in the list, we shouldn't do anything
when you try to active the selected result, since there isn't one.
Fix this by using an Optional<size_t> to store the selected index.
If something happens in response to on_change that causes the widget
to get unparented, creating a GUI::Painter will fail since it can't
find the window to paint into.
Since painting only cares about the syntax highlighting spans, what we
really want is to ensure that spans are up-to-date before we start
painting.
The problem was that rehighlighting and the on_change hook were bundled
together in an awkward lazy update mechanism. This patch fixes that by
decoupling rehighlighting and on_change. Rehighlighting is now lazy
and only happens when we handle either paint or mouse events. :^)
Fixes#8302.
This was causing CrashDaemon to choke on our coredumps. Note that we
didn't care about the validation failures before this change either,
this patch simply reorders the checks to avoid divide-by-zero when
validating an ET_CORE file.
This will run all the tests that are children of this service with
deadly UBSAN, ensuring we don't get any UBSAN regressions in on-target
tests anymore. :^)
The first time we want to print a UBSAN violation, the UBSAN runtime
in userspace will get the UBSAN_OPTIONS environment variable to check if
it contains the string "halt_on_error=1". This is clearly not robust to
invalid options or adding more options, but it gets the job done at the
moment. :^)
The fact that this always reads 16 bytes from the input byte stream
for the key data is still a bit on the suspicious side, but at least
it won't crash UBSAN anymore.
It's alright for this function to be called multiple times, as it quits
early when a partial flush doesn't empty the download buffer.
Relax the assertion to having scheduled "did_finish()" only once.
The time interval for animations is most often described as `duration`
in animation contexts and the `WindowServer::Animation` class
should reflect that.
The Process::Handler type has KResultOr<FlatPtr> as its return type.
Using a different return type with an equally-sized template parameter
sort of works but breaks once that condition is no longer true, e.g.
for KResultOr<int> on x86_64.
Ideally the syscall handlers would also take FlatPtrs as their args
so we can get rid of the reinterpret_cast for the function pointer
but I didn't quite feel like cleaning that up as well.
Neither the kernel nor LibELF support loading libraries with larger
PT_LOAD alignment. The default on x86 is 4096 while it's 2MiB on x86_64.
This changes the alignment to 4096 on all platforms.
Userland faulted on the very first instruction before because the
PML4T/PDPT/etc. weren't marked as user-accessible. For some reason
x86 doesn't care about that.
Also, we need to provide an appropriate userspace stack segment
selector to iretq.
This adds a new ASTNode type called 'NamedType' which inherits from
the Type node.
Previously every Type node had a name field, but it was not logically
accurate. For example, pointer types do not have a name
(the pointed-to type may have one).
It was previously stored as a StringView, which prevented us from
using temporary strings in the 'extra' argument.
The performance hit doesn't really matter because ScopeLogger is used
exclusively for debugging.
The menus always thought they were being outside of the main screen,
which caused them to be left and/or top aligned. This also fixes the
calculation of the available space by using the screen rectangle where
it will be displayed.
This patch adds a new ArgumentsObject class to represent what the spec
calls "Arguments Exotic Objects"
These are constructed by the new CreateMappedArgumentsObject when the
`arguments` identifier is resolved in a callee context.
The implementation is incomplete and doesn't yet support mapping of
the parameter variables to the indexed properties of `arguments`.
We care about showing 'Assistant' app as fast as possible when the
hotkey is pressed. In order to do that, we can parse the `.af` file
ahead of time and have it ready to use.
