Previously, the actual behavior of magic lookup and one described in its
commit description have not matched. Instead of being weak definitions
in a library that is always in the end of load order, the definitions
were normal ones and thus were able to override other weak definitions
in LibC. While this was consistent with how DynamicLoader resolves
ambiguity between normal and weak relocations, this is not the behavior
POSIX mandates -- we should always choose first available definition wrt
load order. To fix this problem, the patch makes sure we don't define
any of magic symbols in LibC.
In addition to this, it makes all provided magic symbols functions
(instead of objects), what renders MagicWeakSymbol class unnecessary.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).
This commit is auto-generated:
$ xs=$(ack -l \bDeprecatedString\b\|deprecated_string AK Userland \
Meta Ports Ladybird Tests Kernel)
$ perl -pie 's/\bDeprecatedString\b/ByteString/g;
s/deprecated_string/byte_string/g' $xs
$ clang-format --style=file -i \
$(git diff --name-only | grep \.cpp\|\.h)
$ gn format $(git ls-files '*.gn' '*.gni')
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
