Similar to POSIX read, the basic read and write functions of AK::Stream
do not have a lower limit of how much data they read or write (apart
from "none at all").
Rename the functions to "read some [data]" and "write some [data]" (with
"data" being omitted, since everything here is reading and writing data)
to make them sufficiently distinct from the functions that ensure to
use the entire buffer (which should be the go-to function for most
usages).
No functional changes, just a lot of new FIXMEs.
We currently fully casefold the left- and right-hand sides to compare
two strings with case-insensitivity. Now, we casefold one code point at
a time, storing the result in a view for comparison, until we exhaust
both strings.
For example, the code point U+002F could be encoded as UTF-8 with the
bytes 0x80 0xAF. This trick has historically been used to bypass
security checks.
This is needed to have code for creating an in-memory sRGB profile using
the (floating-ppoint) numbers from the sRGB spec and having the
fixed-point values in the profile match what they are in other software
(such as GIMP).
It has the side effect of making the FixedPoint ctor no longer constexpr
(which seems fine; nothing was currently relying on that).
Some of FixedPoint's member functions don't round yet, which requires
tweaking a test.
`consume_until(foo)` stops before foo, and so does
`ignore_until(Predicate)`, so let's make the other `ignore_until()`
overloads consistent with that so they're less confusing.
The output of the DeprecatedString::bijective_base_from() is now
correct for numbers larger than base^2.
This makes column names display correctly in Spreadsheet.
This naming scheme matches Vector.
This also changes `take_last` to move the value it takes, and delete by
known pointer, avoiding a full lookup and potential copies.
Instead of rehashing on collisions, we use Robin Hood hashing: a simple
linear probe where we keep track of the distance between the bucket and
its ideal position. On insertion, we allow a new bucket to "steal" the
position of "rich" buckets (those near their ideal position) and move
them further down.
On removal, we shift buckets back up into the freed slot, decrementing
their distance while doing so.
This behavior automatically optimizes the number of required probes for
any value, and removes the need for periodic rehashing (except when
expanding the capacity).
This approximation tries to generate values within 0.1% of their actual
expected value. Microbenchmarks indicate that this iterative SIMD
version can be up to 60x faster than `AK::SIMD::exp`.
For example the words "can't" and "32.3" should not have boundaries
detected on the "'" and "." code points, respectively.
The String test cases fixed here are because "b'ar" is now considered
one word.
This is done by providing Traits<ByteBuffer>::equals functions for
(Readonly)Bytes, as the base GenericTraits<T>::equals is unable to
convert the ByteBuffer to (Readonly)Bytes to then use Span::operator==
This allows us to check if a Vector<ByteBuffer> contains a
(Readonly)Bytes without having to making a copy of it into a ByteBuffer
first. The initial use of this is in LibWeb with CORS-preflight, where
we check the split contents of the Access-Control headers with
Fetch::Infrastructure::Request::method() and static StringViews
such as "*"sv.bytes().
The AnyString concept is currently broken because it checks whether a
StringView is constructible from a type T. The StringView constructors,
however, only accept constant rvalue references - i.e. `T const&`.
This also adds a test to ensure this continues to work.
Having an alias function that only wraps another one is silly, and
keeping the more obvious name should flush out more uses of deprecated
strings.
No behavior change.
