Recent fixes have been made to problems associated with rapidly changing
objexts especially on re-opening of the bookie. Test of rotating
objects from both an index query and a fetch perspective added to better
detect such issues in the future.
To try and improve performance index entries had been removed from the
Ledger Cache, and a shadow list of the LedgerCache (in SQN order) was
kept to avoid gb_trees:to_list on push_mem.
This did not go well. The issue was that ets does not deal with
duplicate keys in the list when inserting (it will only insert one, but
it is not clear which one).
This has been reverted back out.
The ETS parameters have been changed to [set, private]. It is not used
as an iterator, and is no longer passed out of the process (the
memtable_copy is sent instead). This also avoids the tab2list function
being called.
Added basic support for 2i query. This involved some refactoring of the
test code to share functions between suites.
There is sill a need for a Part 2 as no tests currently cover removal of
index entries.
