Data is None if file is missing/deleted in rev.
rt )r rG rT r r r �getfile� s zconverter_source.getfilec C rs )aD Returns a tuple of (files, copies, cleanp2).
files is a sorted list of (filename, id) tuples for all files
changed between version and its first parent returned by
getcommit(). If full, all files in that revision is returned.
id is the source revision id of the file.
copies is a dictionary of dest: source
cleanp2 is the set of files filenames that are clean against p2.
(Files that are clean against p1 are already not in files (unless
full). This makes it possible to handle p2 clean files similarly.)

i is an index selecting one of the parents of rev. The return

this parent.
If rev has no parents, i is None.

and having listed parents. 'commit' is a commit object
containing at a minimum the author, date, and message for this
changeset. 'files' is a list of (path, version) tuples,
'copies' is a dictionary mapping destinations to sources,
'source' is the source repository, and 'revmap' is a mapfile
of source revisions to converted revisions. Only getfile() and
lookuprev() should be called on 'source'. 'full' means that 'files'
is complete and all other files should be removed.
'cleanp2' is a set of the filenames that are unchanged from p2
(only in the common merge case where there two parents).
Note that the sink repository is not told to update itself to
a particular revision (or even what that revision would be)
before it receives the file data.
