rsync - Dec 2009 - File list and find_fuzzy() insights for algo fiddling

Hi!

I read the source around find_fuzzy(), but got stuck in get_dirlist(). I
thought the latter returns the subset of the current ?global? file list
of the receiver side (which is complete, or an incremental part(?)),
reduced to the ?same directory? restriction.

Can someone enlighten me, where the ?global file list? is stored? Is
that actually used for fuzzy-match? If not, why not?


When is recv_generator() invoked? It seems to store some static
fuzzy-related data, but I don?t get the big picture when this data is
updated.


My intention is to augment the fuzzy-search to search in the whole
receiver target subtree.


Thanks,
Robert

There is no such thing.  Since rsync is duplicating the sender's
files, there is only a list of the sender's files in memory except for
some single-directory scanning that the receiving side does.

See the various detect-rename patches for rsync for how to find files
that have moved around.  The patches are mentioned on the download
page of the rsync website.
