retrieving file contents only if changed

[nbecker]

I'm retrieving results (stored in files in pickle format) and storing them locally.  I wanted to retrieve them only if they changed (basically, re-implementing sync_from_cloud).

I used get_md5() and then I calculated the md5 from my local file using;

hashlib.md5 (open (file, 'r').read()).hexdigest()

but it appears the md5 I calculate locally never matches the md5 I get from get_md5().

Any ideas?

Never mind - I got it working - my mistake

Hi,

Glad it all worked out.

Quick question: Was there some functionality you needed that sync_from_cloud didn't offer?

Best,

Aaron

I wanted to know when a file was updated, so I implemented the md5 check myself.
