Basic operation
- pull the latest changes from origin on the specified branch
- iterate over all the expected filenames, skipping any that are missing
- calculate md5 for all the filenames
- compare the md5 to what is in redis
- update redis if the md5s do not match
Redis update
Assuming foo:bar:baz base key:
# redis.connect(redis_options)
GET foo:bar:baz:md5 # assume md5 mismatch
SET foo:bar:baz # file contents
SET foo:bar:baz:md5 # file contents md5
INCR foo:bar:baz:version
