We had an unusual optimization in AK::StringView where constructing
a StringView from a String would cause it to remember the internal
StringImpl pointer of the String.
This was used to make constructing a String from a StringView fast
and copy-free.
I tried removing this optimization and indeed we started seeing a
ton of allocation traffic. However, all of it was due to a silly
pattern where functions would take a StringView and then go on
to create a String from it.
I've gone through most of the code and updated those functions to
simply take a String directly instead, which now makes this
optimization unnecessary, and indeed a source of bloat instead.
So, let's get rid of it and make StringView a little smaller. :^)
Previously this would create new to_lowercase()'d strings from the
needle and the haystack. This generated a huge amount of malloc
traffic in some programs.
This is basically just for consistency, it's quite strange to see
multiple AK container types next to each other, some with and some
without the namespace prefix - we're 'using AK::Foo;' a lot and should
leverage that. :^)
This is an improved version of WrapperGenerator's snake_name(), which
seems like the kind of thing that could be useful elsewhere but would
end up getting duplicated - so let's add this to AK::String instead,
like to_{lowercase,uppercase}().
Personally I found this unintuitive at first, but it is in line with
strtol(), Python's int() or JavaScript's parseInt(), so I guess it makes
sense.
Fixes#4097.
Get rid of the weird old signature:
- int StringType::to_int(bool& ok) const
And replace it with sensible new signature:
- Optional<int> StringType::to_int() const
FileSystemPath::has_extension was jumping through hoops and allocating
memory to do a case insensitive comparison needlessly. Extend the
existing String::ends_with method to allow the caller to specify the
case sensitivity required.
