`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. :^)
