So is there an (almost as) fast way to check whether a folder is

I think the fastest way in the current code would be to call
svn_wc_read_kind() on the directory, maybe after first checking that there
is some .svn in at least one of the parent directories.
I thought about implementing a small cache for that, so that I don't
have to walk up the tree every time to find an .svn dir.
But I thought I read something about such a small cache getting
implemented in the svn library itself so I wanted to ask first - maybe
there's already an API to use that cache. Or maybe I just remember it
wrong.
Does TSVN cache/reuse svn_client_ctx_t handles? In 1.7 the client
context contains an opaque wc context which in turn includes a
database context, svn_wc__db_t. The database context caches sqlite
connections and has a cache mapping directory->database.
No, the TSVN cache doesn't reuse those at the moment. I might change
that though...
Quite when TSVN should create/destroy svn_client_ctx_t is an
interesting question. Reusing a long-lived context (or perhaps a
small number, one per-thread say) is likely to make individual svn
calls faster. However the open database handles means that Windows
won't be able to delete root directories. It's not clear to me how
or when TSVN would close those handles.
That's why I currently don't reuse SVN pools and contexts. There is a
mechanism in place which tells the cache to release all handles, but it
isn't very reliable. I will have to test whether I can reuse the
contexts or whether I have to recreate them.
