		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.

int up__fetch_decoder ( struct estat * sts )

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.

Here is the caller graph for this function:

int up__handle_special	(	struct estat *	sts,
		char *	path,
		char *	data,
		apr_pool_t *	pool
	)

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.

		const char *	utf8_name,
		const svn_string_t *	utf8_value,
		int *	not_handled,
		apr_pool_t *	pool
	)

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.
