(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)
Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.
We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
The name-to-section lookup table was only used in a handful of places,
and none of them were calling it nearly enough to justify building
a cache for it in the first place. So let's get rid of it and reduce
startup time by a little bit. :^)
With the kernel command line issue fixed, we can now enable these
KUBSAN options without getting triple faults on startup:
* alignment
* null
* pointer-overflow
When building the kernel with -O2, we somehow ended up with the kernel
command line outside of the lower 8MB of physical memory. Since we don't
map that area in our initial page table setup, we would triple fault
when trying to parse the command line.
This patch sidesteps the issue by copying the (first 4KB of) the kernel
command line to a buffer in a known safe location at boot.
It's a lot faster to iterate the GNU hash tables if we don't have to
compute the length of every symbol name before rejecting it anyway while
comparing the first character. :^)
When performing a global symbol lookup, we were recomputing the symbol
hashes once for every dynamic object searched. The hash function was
at the very top of a profile (15%) of program startup.
With this change, the hash function is no longer visible among the top
stacks in the profile. :^)
This logging mode was unusable anyway since it spams way too much.
The dynamic loader is in a pretty good place now anyway, so I think
it's okay for us to drop some of the bring-up debug logging. :^)
Also, we have to be careful with dbgln_if(FOO_DEBUG, "{}", foo())
where foo() is something expensive, since it might get evaluated
even if !FOO_DEBUG.
Clangd (CLion) was choking on some of the -fsanitize options, and since
we're not building the kernel with Clang anyway, let's just disable
the options for non-GCC compilers for now.
Don't compute the strlen() of the string we're comparing against first.
This can save a lot of time if we're comparing against something that
already fails to match in the first few characters.
Thanks to @trflynn89 for the neat implicit consteval ctor trick!
This allows us to basically slap `CheckedFormatString` on any
formatting function, and have its format argument checked at compiletime.
Note that there is a validator bug where it doesn't parse inner replaced
fields like `{:~>{}}` correctly (what should be 'left align with next
argument as size' is parsed as `{:~>{` following a literal closing
brace), so the compiletime checks are disabled on these temporarily by
forcing them to be StringViews.
This commit also removes the now unused `AK::StringLiteral` type (which
was introduced for use with NTTP strings).
We implement this by adding a BlockBox::is_scrollable() helper,
and then ignoring wheel events for non-scrollable boxes.
Thanks to FireFox317 for pointing this out! :^)
When files where placed in outside of the project root, they would
appear empty because the label in the tree would differ from the
actual file path relative to the root.
Fixes#5471.
This is rather crude, but you can now use the mouse wheel to scroll up
and down in block-level boxes with clipped overflowing content.
There's no limit to how far you can scroll in either direction, since
we don't yet track how much overflow there is. But it's a start. :^)
We now apply a paint-time clip to the padding rect of a BlockBox before
painting its inline-level children. This covers some of the behavior
we want from "overflow: hidden" etc but is far from a complete solution.
Handling crashes synchronously is finicky since we're modifying the
m_client_state struct while in a callback lambda owned by it.
Let's avoid all the footguns here by simply using deferred_invoke()
and handling the crash on next event loop iteration instead.
Also, only mark the menu bar item as opened if a menu was actually
opened through the menu bar.
These changes allow a menu to be used both in the menu bar as well
as a context menu.
Fixes#5469
