Feature request: changed svn_ra_get_file(), new svn_delta_action missing_bytes

["Ph. Marek" <ph...@bmlv.gv.at>]

Hello everybody,


I'd like to ask for another feature.
I'd need a function like svn_ra_get_file(), but which gets a list of (start, 
length) range tuples, and returns only these bytes.
Depending on how these ranges are returned (callback would be ok, delta stream 
too) a new svn_delta_action missing_bytes or similar might be necessary.

The need arises from fsvs. There I have no text-base, but I'd like to get 
delta operations. So I do manber-hashing with some (big) blocksize (about 
128kB), and remember the MD5 and manber-hash of the original blocks.
Now if the file changes locally, I'd do the manber-hashing again, know which 
blocks have changed, and only submit them.

On update I'd query a property of the repository file, know which blocks I 
already have locally, and only request the others.


We might use svn_txdelta_source for the "old" data, but that's not really the 
meaning, if we just query for 


Summarizing, this would allow for rsync-like operations against files in the 
repository.


May I create an issue?


Thank you.


Regards,

Phil
