Note that this still keeps the old behaviour of putting things in std by
default on serenity so the tools can be happy, but if USING_AK_GLOBALLY
is unset, AK behaves like a good citizen and doesn't try to put things
in the ::std namespace.
std::nothrow_t and its friends get to stay because I'm being told that
compilers assume things about them and I can't yeet them into a
different namespace...for now.
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
These are mostly minor mistakes I've encountered while working on the
removal of StringView(char const*). The usage of builder.put_string over
Format<FormatString>::format is preferrable as it will avoid the
indirection altogether when there's no formatting to be done. Similarly,
there is no need to do format(builder, "{}", number) when
builder.put_u64(number) works equally well.
Additionally a few Strings where only constant strings were used are
replaced with StringViews.
The ASN.1 decoder was originally using AK::BitmapView for decoded
BitStrings, however the specification requires that the bits are stored
in a byte from the most significant to the least significant.
Storing three bits '110' would result in a byte '1100 0000', i.e. 0xC0.
However, AK::BitmapView expects the bits to be stored at the bottom like
'0000 0110', i.e. 0x06. For the current uses the data was always a
multiple of eight bits, resulting in complete bytes, which could
directly be interpreted correctly.
For the implementation of the key usage extension of certificates the
correct implementation of the BitString is required.
ASN.1 encodes booleans as false is zero and true is non-zero. The
decoder currently returned true when the boolean was zero.
Since this decoder was barely used it did not cause any problems,
however for support of other certificate extensions the correct version
is required.
This isn't a complete conversion to ErrorOr<void>, but a good chunk.
The end goal here is to propagate buffer allocation failures to the
caller, and allow the use of TRY() with formatting functions.
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.
