CBL Replication states

[Matt Quinn]

Hi all,

I'm working on unit tests so I can file an issue about unexpected results from CBL Android's Replication.isRunning() and getStatus() methods, but first I want to confirm what the expected states are.

This is my best guess at the expected results. Do these look right?

Thanks,
Matt

Jens it's probably best for you to confirm this.

I've added comments on the gist.

Perfect, thanks Jens! You even anticipated my next question about how
continuous replications deal with error states.

If a one-shot replication hits an error, does it retry itself as well,
or simply record the error and stop? (The intended behaviour, I mean; I
understand Android might not have implemented it yet).

Thanks,
Matt

The intention is that it should retry on some classes of error that are likely to be transitory, like host-not-found* or connection-dropped. (I'm being weaselly with the language because I suspect that in the iOS implementation not all cases of this are handled.) But a non-transitory error like a 403 will cause it to stop.

The retry uses an exponential back-off and gives up after a minute or so.

Hi Jens & Traun,

Any idea on when's reachability going to get implemented on Android?

I don't have an ETA, but since we are currently in the middle of splitting the Couchbase Lite Android projects and repos into a pure java and Android specific libraries, it will happen sometime after that. 

I'm planning to send a follow up email once that plan is nailed down a bit further.
