This allows you to do things like:
vector.insert_before_matching(value, [](auto& entry) {
return value < entry;
});
Basically it scans until it finds an element that matches the condition
callback and then inserts the new value before the matching element.
The first implementation class is DebugLogStream, which can be used like so:
dbg() << "Hello friends, I am " << m_years << " years old!";
Note that it will automatically print a newline when the object created by
dbg() goes out of scope.
This API will grow and evolve, so let's see what we end up with :^)
Instead of manually doing String::format("%d"/"%u") everywhere, let's have
a String API for this. It's just a wrapper around format() for now, but it
could be made more efficient in the future.
Solve this by adding find() overloads to HashTable and SinglyLinkedList
that take a templated functor for comparing the values.
This allows HashMap to call HashTable::find() without having to create
a temporary Entry for use as the table key. :^)
This is prep work for supporting HashMap with NonnullRefPtr<T> as values.
It's currently not possible because many HashTable functions require being
able to default-construct the value type.
Update ProcessManager, top and WSCPUMonitor to handle the new format.
Since the kernel is not allowed to use floating-point math, we now compile
the JSON classes in AK without JsonValue::Type::Double support.
To accomodate large unsigned ints, I added a JsonValue::Type::UnsignedInt.
The LibC build is a bit complicated, since the toolchain depends on it.
During the toolchain bootstrap, after we've built parts of GCC, we have
to stop and build Serenity's LibC, so that the rest of GCC can use it.
This means that during that specific LibC build, we don't yet have access
to things like std::initializer_list.
For now we solve this by defining SERENITY_LIBC_BUILD during the LibC
build and excluding the Vector/initializer_list support inside LibC.
Get rid of the ConstIterator classes for these containers and use templated
FooIterator<T, ...> and FooIterator<const T, ...> helpers.
This makes the HashTable class a lot easier to read.
This means you can now do this:
void harmonize(NonnullRefPtrVector<Voice>& voices)
{
for (auto& voice : voices) {
voice.sing(); // Look, no "->"!
}
}
Pretty dang cool :^)
This is a slot-in convenience replacement for Vector<NonnullRefPtr<T>> that
makes accessors return T& instead of NonnullRefPtr<T>&.
Since NonnullRefPtr guarantees non-nullness, this allows you to access these
vector elements using dot (.) rather than arrow (->). :^)
This avoids putting pressure on kmalloc() during backtrace symbolication.
Since we dump backtrace for every process that exits, this is actually a
decent performance improvement for things like GCC that chain a lot of
processes together.
This parser assumes that the JSON is well-formed and will choke horribly
on invalid input.
Since we're primarily interested in parsing our own output right now, this
is less of a problem. Longer-term we're gonna need something better. :^)
- Delete the default constructor instead of just making it private.
It's never valid to create an empty NonnullRefPtr.
- Add copy assignment operators. I originally omitted these to force use
of .copy_ref() at call sites, but the hassle/gain ratio is minuscule.
- Allow calling all the assignment operators in all consumable states.
This codifies that it's okay to overwrite a moved-from NonnullRefPtr.
