		void **	handler_baton
	)

File handle pools.

This is a bit complicated.

With the file:/// protocol, the source and destination filehandles are not closed by the subversion libraries; with svn+ssh:/// they are.

If we just do a apr_file_close(), we get the error EBADF (bad filehandle), and would accordingly die.

If we don't do it (and let apr_pool_cleanup close it), the close may just fall into the next second, and our (in up__close_file) cached ctime is wrong - so we'd mark this entry as changed.

One solution would be to do a apr_file_close(), and ignore EBADF; this is a bit unclean.

So we go the other route: we simply define a subpool, where we allocate the handles in, and clear that later. That has the additional advantage that the struct estat could possibly be shrinked in the future.

Prefetch update-pipe property.

In case we're updating an existing file, we won't get all properties sent - only changed. So we have to look for existing properties if we need them.

int up__handle_special	(	struct estat *	sts,

Handling non-file non-directory entries.

We know it's a special file, but not more; we have to take the filedata and retrieve the type.

After this call sts->st.mode and sts->new_rev_mode_packed are set to the current value.

Parse subversion properties for the given entry.

Parse subversion properties for the given entry.

If not_handled is not NULL, it gets set to 1 if this property is not handled; so the caller knows that he has to to write the property into some other storage if he wants to keep it.

Note:

not_handled does not get set to 0; pre-populating is left to the caller.

Recursively delete a directory structure.

Only non-changed, known entries, so we don't remove changed data.

If an entry does not exist (ENOENT), it is ignored.

Only entries that are registered from URLs given on the command line (with -u) are removed.

If children that belong to other URLs are found we don't remove the directory.
