	)

General function to get a file into a stream.

This function fetches an non-directory entry loc_url from the repository in current_url, and writes it to output - which gets closed via svn_stream_close().

decoder should be set correctly.

Todo:: if it's NULL, but an update-pipe is set on the entry, the data has to be read from disk again, to be correctly processed.

No meta-data is set, and the svn:special attribute is ignored.

The revision number must be valid, it may not be SVN_INVALID_REVNUM.

If sts_for_manber is NULL, no manber hashes are calculated.

If output_sts is NULL, the meta-data properties are kept in props; else its fields are filled (as far as possible) with data. That includes the estat::repos_rev field.

The user-specified properties can be returned in props.

As this just returns the data in a stream, the files' type mostly doesn't matter; it just may not be a directory, because we'd get an error from subversion.

loc_url must be given in the current locale; it will be converted to UTF8 before being sent to the subversion libraries.

		struct estat *	output_sts,
		apr_hash_t **	props,
		apr_pool_t *	pool
	)

Gets the entry into a temporary file.

Mostly the same as rev__get_text_to_stream(), but returning a (temporary) filename based on filename_base, if this is not NULL.

The entries' file type isn't taken into account; the file may have the data "symlink XXX", etc.

If filename_base is NULL, the file will be put in a real temporary location.

output_stat is used to store the parsed properties of the entry.

int rev__install_file	(	struct estat *	sts,
		svn_revnum_t	revision,
		char *	decoder,
		apr_pool_t *	pool
	)

Gets a clean copy from the repository.

Meta-data is set; an existing local entry gets atomically removed by rename().

If the entry has no URL defined yet, but has a copy flag set (RF_COPY_BASE or RF_COPY_SUB), this URL is taken.

If revision is 0, the BASE revision is and decoder is used; this is the copy base for copied entries.
