get_all_collections only goes one level deeper

[387809109]

I was trying to call get_all_collections to recursively get all collections within a root catalog. It turned out that only collections of the root catalog and its direct children are returned.

Looking at the code

pystac/pystac/catalog.py

Line 455 in ff67de3

def get_all_collections(self) -> Iterable[Collection]:

def get_all_collections(self) -> Iterable[Collection]:
    """Get all collections from this catalog and all subcatalogs. Will traverse
    any subcatalogs recursively."""
    yield from self.get_collections()
    for child in self.get_children():
        yield from child.get_collections()

It seems that it's expected to only return collections from self and children.

Is it intentional or a bug?

That looks like a bug to me. I think that second yield should be child.get_all_collections(). I can open a PR now.
