Naming is now confusing now we have TicTac Trees. This query builds a
list of keys and hashes not a tree - so it was misleading anyaway. Now
renamed hashlist_query.
This at least checks the file is present, and the Key exists in the
index of that file. If the value is corrupt it will be removed by
compation, and then this will fail (unless the file is never compacted).
TODO: resolve issus of files which are corrupt - but never compacted
- a job for backup?
Clena the API of Riak specific methods, and also resolve timing issue in
simple_server unit test. Previously this would end up with missing data
(and a lower sequence number after start) because of the penciller_clerk
timeout being relatively large in the context of this test. Now the
timeout has bene reduced the L0 slot is cleared by the time of the
close. To make sure an extra sleep has been added as a precaution to
avoid any intermittent issues.
Busted the hashtable in a Journal file, and demonstrated it can be fixed
by changing the extension name (no need to recover from backup if only
the hashtable is bust)
Changes the stratup otpions to a prolist to make it easier to get
environment variables as default.
Tried application:start - and completely baffled as to how to get this
to work.
