In a bunch of cases, this actually ends up simplifying the code as
to_number will handle something such as:
```
Optional<I> opt;
if constexpr (IsSigned<I>)
opt = view.to_int<I>();
else
opt = view.to_uint<I>();
```
For us.
The main goal here however is to have a single generic number conversion
API between all of the String classes.
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')
These syscalls are not necessary on their own, and they give the false
impression that a caller could set or get the thread name of any process
in the system, which is not true.
Therefore, move the functionality of these syscalls to be options in the
prctl syscall, which makes it abundantly clear that these operations
could only occur from a running thread in a process that sees other
threads in that process only.
This method can be used to force the current process to sleep, waiting
for a debugger to attach. On attach, the debugger breaks at the callsite
directly.
This is tested on Linux and macOS, in Clion and also terminal gdb and
lldb.
`Process::get_name()` and `Process::set_name()` are basically the same
as `get_process_name()` and `set_process_name()`, except making use of
convenient Serenity standard types and returning ErrorOr, instead of
char* and errno shenanigans.
`Process::set_name()` has an optional `SetThreadName` parameter, for
when you also want to set the thread's name to the same thing. That's
true for the two places that use `set_process_name()`.
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 :^)
These were accidental (or leftover) uses of String::characters() to
construct StringViews through its StringView(char const*) constructor.
Since this constructor is due to be removed, this will no longer work.
Plus this prevents strlen from being run on these strings unnecessarily.
This makes the wrapper more like the rest in LibCore, and also
removes the annoying limitation of not supporting arguments.
There are three overloads one for String, char const *, and StringView
argument lists. As long as there are <= 10 arguments the argv list
will be allocated inline, otherwise on the heap.
This is a simple wrapper around posix_spawn() that will help us simplify
a bunch of very verbose posix_spawn() invocations.
This first version only supports the simplest case: executing an
executable without passing arguments or doing anything fancy. More
features can be added to cover more cases. :^)
