I'm pretty sure someone has pointed this out to you before but why don't
you just use svn_ra_get_latest_revnum?
Sure you have to do the bother to setup an RA session but it's not any
harder to setup an RA session than it is a client ctx since the client
lib is using what you give it to setup the RA session.
Probably could get away with leaving all of the function pointers in
svn_ra_callbacks_t set to NULL and only setting the auth_baton (which
you have to set for a client ctx too).
If you've already got a ctx, you could just do something like this:
svn_error_t *my_client_get_latest_revnum (svn_client_ctx_t *ctx,
const char *repos_URL,
svn_ra_callbacks_t *ra_callbacks = ap_pcalloc (pool, sizeof(*ra_callbacks));
ra_callbacks->auth_baton = ctx->auth_baton;
SVN_ERR (svn_ra_open (&ra_session, repos_URL, ra_callbacks, NULL,
return svn_ra_get_latest_revnum (ra_session, latest_revnum, pool);
(Note that's untested and largely off the top of my head but it ought to
Then you don't have to worry about versions of the server nor getting
any extra data across the network that you don't really need.
