Proposed changes to migrate to 2.0

browserid support

  • token server and metadata tokens

max individual request size

  • right now we limit (not implemented in python!) wbo size, but not total size. Restrict post body size to 1M?

drop parentid

drop predecessorid

talk to rnewman/gps about preferred way to transmit timestamps

  • figure out how to get the timestamp into integer precision

405 for wrong method

  • Cornice probably buys us this directly

304 not modified when X-Weave-Timestamp < current

  • Saves processing the request body

drop whoisi as a return format

delete /storage takes multiple collections

  • Will give us the ability to delete "everything except keys" without using a loop

Proposed changes to migrate to 2.1

generate better docs for how to implement backoff on client

sync sesssions with server-generated token - helps avoid races

  • generated on write without auth token if none exists on server side
  • can't write if there's a token in place without it. Can't read? (may be inconsistent)
  • need a way to have client expire token and length after which it autoexpires
  • make it part of auth protocol


way to let the server know that there's a data problem

  • have a flag that says "this account reported corrupted" to handle HMAC mismatches, etc
  • Maybe in metaglobal?
  • is this a storage problem? or particular to sync
