The alternative here, of course, is to actually add these methods as finalizers to the relevant objects: this would probably make more sense in the long run (as a benefit, we wouldn't need to then deprecate the finalize methods, as these would be implicit).

@wildart Do you know why we don't use object finalizers for these?

@simonbyrne

I've cleaned this up so that most now actually act like finalizers. This can't be used for StrArrayStruct and Buffer though, as they're immutable, but these aren't really user facing.

upstream(head(repo)) ? does this not need with(head(repo)) any more?

Hmm, something got broken in the rebase. I'll try to figure out what happened.

Are there any requirements from libgit2 that objects should be freed "quickly" as they are when using the with form? Or is it fine to just delay the freeing until whenever the finalizers are run?

@simonbyrne

Not that I can tell, no.

In fact, we could probably clean up the code quite a bit by getting rid of all the with statements.

Unless I guess anything on the C side holds open file handles that we'd like to delete or similar?

That could be, but the libgit2 docs are pretty sparse in that regard.
