Flavio Junqueira commented on ZOOKEEPER-882:
--------------------------------------------
I agree with your description of the behavior of next, and sounds right to me
that we should be setting hdr and calling "return next();" at the end of the
catch block.
Regarding init(), we first use the value of zxid to determine which log files
to read: all log files tagged with a value higher than zxid and the last log
file that is less than zxid. Next we iterate over the log files until
hdr.getZxid() is greater or equal to zxid (should be zxid really). This
guarantees that the next call to next(), after init() returns, will return
zxid+1. Does it sound right to you?

> On startup, the server first loads the latest snapshot, and then loads from
> the log starting at the last transaction in the snapshot. It should begin
