Refactors menubar creation to avoid a null parent window during
construction; moves search options to the more traditional edit
menu; creates and exclusive action group for bytes per row
Fixes#5177 in part
Commit 6a6f19a72 broke the cell position display in the top left of the
Spreadsheet window and the title of the cell type dialog, causing the
application to crash when interacting with cells beyond column FE.
This was another vestige from a long time ago, when exiting a thread
would mutate global data structures that were only protected by the
interrupt flag.
This was necessary in the past when crash handling would modify
various global things, but all that stuff is long gone so we can
simplify crashes by leaving the interrupt flag alone.
Rather than invalidating the entire window, which is very expensive on
the transparent desktop widget, just invalidate the areas that actually
need updating.
It's possible that pending invalidation rectangles haven't been
flushed when processing a paint event. Handle them right away,
which avoids another round trip.
Make more of the kernel compile in 64-bit mode, and make some things
pointer-size-agnostic (by using FlatPtr.)
There's a lot of work to do here before the kernel will even compile.
calloc() was internally calling malloc_impl() which would scrub out
all the allocated memory with the scrub byte (0xdc). We would then
immediately zero-fill the memory.
This was obviously a waste of time, and our hash tables were doing
it all the time. :^)
In line wrapping mode, the same column refers both to the end of a
visual line and the beginning of the subsequent visual line. This
meant that the cursor couldn't move to the beginning of a visual
line. Now, we only let the cursor go to the end of a physical line,
not the visual line.
Closes#4786
This will make constructing (and destructing) Positions a lot cheaper
(as it no longer needs to ref() and unref() a String).
Resulted from #5483, but doesn't fix it.
Let's help our future selves find this problem sooner next time it
happens. Hopefully we'll come up with a nicer loader before then,
but who knows. :^)
Instead of having a special case in the dynamic loader where we ignore
TM-related GCC symbols, just stub them out in LibC like we already do
for various other things we don't support.
A new operator, operator""sv was added as of C++17 to support
string_view literals. This allows string_views to be constructed
from string literals and with no runtime cost to find the string
length.
See: https://en.cppreference.com/w/cpp/string/basic_string_view/operator%22%22sv
This change implements that functionality in AK::StringView.
We do have to suppress some warnings about implementing reserved
operators as we are essentially implementing STL functions in AK
as we have no STL :).
Instead of writing to the userspace utsname struct one field at a time,
build up a utsname on the kernel stack and copy it out to userspace
once it's finished. This is both simpler and gets validity checking
built-in for free.
Found by KUBSAN! :^)
Fixes#5499.
