Allow observers to watch for resource 401s and to specify a new uri to request. Test to make sure "weave:resource:status:401" gets notified and resource handles uri changes.
Save the time the tracker adds a new changed id and use that to compare the age of the record on the server vs the age of the local change to decide if it's server wins or client wins. Fix up various direct uses of changedIDs to use the API and make the save-to-disk lazy to avoid excessive writes. Add a test to make sure addChangedID only increases in time.
Start an abortTimer onStartRequest and refresh the timer on each onDataAvailable only to cancel on an onStopRequest. If the timer triggers, the sync/async call will be aborted.
Inline various _init calls and do super's init with <Super>.call(this, args..). Add various get/set sugar to those missing e.g., meta.keyring. Also simplify crypto record creation by setting cleartext in the parent.
Include the URI on success/fail requests and only trace log the onStartRequest. Switch various debug messages to trace and remove importing Log4Moz in fx-weave-overlay and generic-change. Drop the rootLogger to Debug to not log trace messages from unpreffed loggers.
Get rid of Filters and automatically JSON.stringify PUT/POST data that aren't strings, so plain Records can be passed in to PUT and POST. This leverages toJSON of Records to provide an object that can be serialized. Fix up client record serialize/deserialize to still escape/unescape non-ASCII.
Always allow getting an object representation of potentially JSON response for any Resource instead of explicitly on filterDownload. Update existing Resource GETs that manually parse the response. This prevents the String response from accidentally toString()ing a filteredDownload that converted to a different type.
Get rid of lastChannel and return a String object from _request with additional properties of status, succeeded, headers -- even if the response was handled by cache. Update engines to check for non-success and throw the failure. Update tests to use these additional properties instead of lastChannel, etc.
Wrap the error code with a JS Error to track the stack, and re-wrap it to get the full stack trace. Also, remove args for __request for the stack because it's sometimes the whole record..
Incrementally process records as the collection finds record boundaries and converts them to records for the engine to use. Get rid of the collection iterator and original RecordParser. Add tests for incremental record parsing and remove old iter tests.
