`read_bool_entry()` can now interpret both integers (1 or 0) and
Boolean strings ("true" or "false") in configuration files.
All values other than "1" or "true" are considered false.
It was impractical to return a RefPtr<File> since that left us no way
to extract the error string. This is usually needed for the UI, so the
old static open() got basically no use.
The event that triggered the exit from an inner event loop would always
get re-delivered in the outer event loop due to a silly off-by-one
mistake when transferring pending events between loops.
This helper opens a file with a given name, mode and permissions and
returns it in a RefPtr<File>. I think this will be a bit nicer to use
than having to go through Core::File::construct() every time.
The kernel was already using the UDP prefix, and the TCP LibCore classes
are also uppercased. Let's rename for consistency.
Also order the LibCore Makefile alphabetically, because everywhere else
seems to be doing that :)
Add a SetInspectedObject call that tells us which Core::Object a remote
client is currently looking it. Objects get notified when they gain
their first inspector, and when they lose their last one.
Since the returned object is now owned by the callee object, we can
simply vend a ChildType&. This allows us to use "." instead of "->"
at the call site, which is quite nice. :^)
Previously, this function was using `AK::String::to_uint()`, which is
wrong considering the function returns type `int`. This also means that
configuration files would revert to the default value on negative
values.
Consider the old pattern for creating a Core::Object parent and child:
auto parent = Core::Object::construct(...);
auto child = Core::Object::construct(..., parent);
The above was an artifact of the pre-reference-counting Object era.
Now that objects have less esoteric lifetime management, we can replace
the old pattern with something more expressive:
auto parent = Core::Object::construct(...);
auto child = parent->add<Core::Object>(...);
This reads a lot more naturally, and it also means we can get rid of
all the parent pointer arguments to Core::Object subclass constructors.
This is just to have a pleasant way to print the current time for now:
dbg() << Core::DateTime::now();
Or if you want it as a string:
Core::DateTime::now().to_string();
This was only used by HashTable::dump() which I used when doing the
first HashTable implementation. Removing this allows us to also remove
most includes of <AK/kstdio.h>.
