Re: [ZODB-Dev] Zodb with Yaml
Hmm. A scan of the files in ZODB and persistence also turn up the conflict resolution code, the import/export machinery, and FileStorage. And a bunch of tests. And maybe the pickle cache and cPersistence.c (although I haven't looked closely enough at that code to know if it would need to be modified, maybe the function names in the code are misleading). - C On Mar 19, 2006, at 2:37 PM, Dieter Maurer wrote: Chris McDonough wrote at 2006-3-18 20:58 -0500: If yaml (or pysyck) supports all of the features of pickle, it's theoretically possible.

Re: [ZODB-Dev] Zodb with Yaml
If yaml (or pysyck) supports all of the features of pickle, it's theoretically possible. You would need to track down all of the places in ZODB where the code serializes and deserializes data from pickle format and write alternate serializing/deserializing logic. But AFAIK the serialization code in ZODB is not very "pluggable". As a result, it would be a nontrivial thing to do, especially given that some serialization-sensitive portions of ZODB are written in C. So I suspect that this is one of those questions that has an answer that goes something like "assuming it's worth the effort, if you need to ask, the answer is yes." ;-) You might want to try adapting Durus instead as I believe it's written entirely in Python. - C On Mar 18, 2006, at 1:21 PM, Chris Spencer wrote: Just out of curiosity, would there be any huge technical hurtles to getting Zodb to use Yaml for serialization instead of Pickle?
