This percent encodes/decodes the request URI when creating or parsing
raw HTTP requests. This is necessary because AK::URL now contains
percent decoded data, meaning we have to re-encode it for creating
raw requests.
This removes URLParser, because its two exposed functions, urlencode()
and urldecode(), have been superseded by URL::percent_encode() and
URL::percent_decode(). This is in preparation for the introduction of a
new URL parser.
This replaces all occurrences of those functions with the newly
implemented functions URL::percent_encode() and URL::percent_decode().
The old functions will be removed in a further commit.
Previously we didn't check that the selection's row index is in a valid
range before attempting to access its data via the model.
This could cause an out-of-bounds access to the model's Vector of
suggestions.
I think this should fix#7404, but I can't verify it does because
I wasn't able to reproduce it on my machine.
JPGLoader used to store component information in a HashTable, indexed
by the ID assigned by the JPEG file. This was fine for most purposes,
however after f89e8fb7 this was revealed to be a flawed implementation
which causes non-deterministic iteration over components.
This issue was previously masked by a perfect storm of int_hash being
stable for the integer values 0, 1 and 2; and AK::HashTable having just
the right amount of buckets for the components to be ordered correctly
after being hashed with int_hash. However, after f89e8fb7,
malloc_good_size was used for determining the amount of space for
allocation; this caused the ordering of the components to change, and
images started showing up with the red and blue channels reversed. The
issue was finally determined to be inconsistent ordering after randomly
changing the order of the components caused Huffman decoding to fail.
This was the result of about 10 hours of hair-pulling and repeatedly
doing full rebuilds due to bisecting between commits that touched AK.
Gunnar, I like you, but please don't make me go through this again. :^)

The Context and Software Rasterizer now gets the array of texture units
instead of a single texture object. _Technically_, we now support some
primitive form of multi-texturing, though I'm not entirely sure how well
it will work in its current state.
When using BIND_NOW (e.g. via -Wl,-z,now) we would fail to load ELF
images while doing relocations when we encounter a weak symbol. Instead
we should just patch the PLT entry with a null pointer.
This can be reproduced with:
$ cat test.cpp
int main()
{
std::cout << "Hello World!" << std::endl;
}
$ g++ -o test -Wl,-z,now test.cpp
$ ./test
did not find symbol while doing relocations for library test: _ITM_RU1
Previously ByteBuffer::grow() behaved like Vector<T>::resize().
However the function name was somewhat ambiguous - and so this patch
updates ByteBuffer to behave more like Vector<T> by replacing grow()
with resize() and adding an ensure_capacity() method.
This also lets the user change the buffer's capacity without affecting
the size which was not previously possible.
Additionally this patch makes the capacity() method public (again).
Avoid promotion of static strings to AK::String, instead use
AK::StringView and operator ""sv, to force string view's instead
which avoids allocation of String. This code path isn't hot enough
that it makes a huge difference, but every bit counts.
This only affects malformed RSA keys. Instead of accepting and
continuing with potentially broken pointers (and in ASAN, crashing), we
now consider bitmaps malformed, and stop parsing.

POSIX (`errno(3p)`) states that errno should not be set to zero.
This helps with applications that don't expect errno to get updated
unless an intermediate syscall also fails.
Previously there was no way to output an empty value into the shadow
file entries when the spwd members were disabled. This would cause new
user entries to the shadow file to be cluttered with disabled values.
This commit checks if the spwd member value is diabled (-1) and will
output as appropriate.
wint_t is also not supposed to be defined by sys/types.h, but should
be defined in wchar.h instead. Since we require it for our definition of
btowc, let's move it to the correct place.
The wrong shift effectively set the upper byte to 0, meaning that
durations longer than 255 centiseconds (2.55 seconds) were wrapped
around. See serenity-fuzz-corpora for an example.
Our "frame" concept very closely matches what the web specs call a
"browsing context", so let's rename it to that. :^)
The "main frame" becomes the "top-level browsing context",
and "sub-frames" are now "nested browsing contexts".
The index of the tree column will not change while painting.
Neither will the number of columsn. So avoid a whole bunch of virtual
function calls by caching these two values at the start of painting.
Textures are now initialized with a nullptr upon generation.
They are only actually created once they are bound to a target.
Currently only the GL_TEXTURE_2D target is supported.
The software rasterizer now allows rendering with or without
a bound TEXTURE_2D.
