I'm upgrading to CBL 1.1.0 from CBL 1.0.3.1. Upon initial replication from
CouchDB to CBL we show a progress bar using code similar to this.
*double* progress = 0.0;
*double* total = *self*.pullReplication.changesCount + *self*.
pushReplication.changesCount;
*unsigned* completed = *self*.pullReplication.completedChangesCount +
*self*.pushReplication.completedChangesCount;
progress = completed / total;
NSLog(@"%f%@ - %u / %f", progress * 100, @"%", completed, total);
We then use `progress` to show a progress bar. However the `total` seems
to grow over a period of time during the replication making the `progress`
percentage kind of useless as the percentage goes up and down not giving
the user any useful information of actual progress.
Is there anything to be done to determine the actual total `changesCount`
for pushing and pulling so the `progress` bar becomes useful again? Is
this a CBL 1.1.0 bug or just the expected behavior that just happened to
work previously in CBL 1.0.3.1?
Here's sample data output from the `NSLog` above.
