in the intro page about the Simple Deployment Template:
- removed the note about the BigchainDB Testnet for now
- changed the link to the docs about contributing to BigchainDB from Markdown to RST
* Updated changelog for 2.0.0b7
* Change 2.0.0b3 to b7 in network-setup.md
* Updated k8s yamls for 2.0.0b7 release
* Updated version.py for 2.0.0b7 release
1. Save pre-commit state in the beginning of end block.
2. Provide an interface for custom elections to rollback on crash recovery.
3. Simplify pre-commit management.
4. Add crash recovery for updert-validator and chain migration elecitons.
* Copy-edited the log rotation page (docs)
* Fix and add some hyperlinks re/ logging.
* Add back the section/link to log-rotation.html
* Correct the location of BigchainDB logs. Omit mention of bigchaindb-benchmark.log
* Revive notes re BigchainDB Server log rotation
* Problem: Outputs API doesn't respond with correct unspent/spent outputs
Solution: Fix fastquery such that embedded document is queried properly
* Problem: key order agnostic queries not implemented
Solution: get_spent queries embedded documents which respect key order. This is
not expected by the application hence the query should be altered to query any
kind of key order
* Problem: Mongo query for get_spent too complicated
Solution: Simplify query using $elemMatch
* Problem: No test for checking mixed spent outputs
Solution: Add test for `get_spending_transactions` to check that correct
matching is done when querying documents with multiple inputs
* Problem: tranasction ids not assert when getting spent outputs
Solution: assert tranasction ids
* Separate pending and effective validator updates.
- Pending validator updates do not prevent elections from concluding.
- ValidatorElection overrides has_conclude to not conclude when there is a pending update for the matching height.
- Effective validator updates deem past elections inconclusive.
* Problem: Looking for election block is inefficient.
Solution: Record placed elections, update the records upon election conclusion.
* Clarify the conclusion order in Election.process_blocks.
* Insert election records in bulk.
Otherwise, one can significantly slow nodes down by posting a whole bunch of unique elections.
* Change get_election to use find_one.
* Calculate total votes without making extra query.
* Fix the pending valset check.
* Fix election test setup.
