rerecord all the storageserver patches in one go darcs was dying trying to deal with the conflict resolution patches. this adds a (very rough) bucketstore and storageserver. probably needs lots of work both in api and implementation. 2006-12-01 03:14:23 +00:00			`from base64 import b32encode, b32decode`

rearrange encode/upload, add URIs, switch to ReplicatingEncoder Added metadata to the bucket store, which is used to hold the share number (but the bucket doesn't know that, it just gets a string). Modified the codec interfaces a bit. Try to pass around URIs to/from download/upload instead of verifierids. URI format is still in flux. Change the current (primitive) file encoder to use a ReplicatingEncoder because it provides ICodecEncoder. We will be moving to the (less primitive) file encoder (currently in allmydata.encode_new) eventually, but for now this change lets us test out PyRS or zooko's upcoming C-based RS codec in something larger than a single unit test. This primitive file encoder only uses a single segment, and has no merkle trees. Also added allmydata.util.deferredutil for a DeferredList wrapper that errbacks (but only when all component Deferreds have fired) if there were any errors, which unfortunately is not a behavior available from the standard DeferredList. 2007-01-16 04:22:22 +00:00			`assert isinstance(i, str), "tried to idlib.b2a non-string '%s'" % (i,)`
