* Replace double quotes with single quotes (flake8)
* Test event subscriber to tendermint via ws
* Problem: Tendermint is not part of stack for CI
Solution: Add Tendermint to stack for CI. For simplicity's sake
docker-compose is being used.
* Add SSL support for MongoDB connections
* Tests for TLS connectivity and other fixes
* Add test for ssl parameters
* Add test for AuthenticationError
* Cleanup branch
* Split env vars as per @r-marques suggestion
* Remove SSL_ENABLED and use BIGCHAINDB_DATABASE_SSL instead
* Changes as per comments from @r-marques
* Remove redundant tests
* Test for ConfigurationError
* Added replicaset name to bigchaindb config
* changed travis replSet to match bigchaindb default
* Updated initialize_replica_set
It now initializes the replica set with the name provided by the
bigchaindb config file.
* initialize_replica_set is now called when creating a mongodb connection.
This way we are sure that a replica set exists when we return a
connection.
* Moved the initialize replica set logic to the connection.
* update the config documentation
* Remove asset.validate_asset and move its validation checks to other areas
* Move Asset.get_asset_id to Transaction
* Remove Asset and AssetLink models
* Add test against creating TRANSFER transactions with bad asset
* Allow AssetLinks to be used in place of Assets in the Transaction Model and enforce `Transaction.transfer()` to only take an AssetLink
* Remove AssetLink's inheritance from Asset
* Remove id from the Asset model
* Fix get_txids_by_asset_id query for rethinkdb after removing asset's uuid
Because `CREATE` transactions don't have an asset that contains an id
anymore, one way to find all the transactions related to an asset is to
query the database twice: once for the `CREATE` transaction and another
for the `TRANSFER` transactions.
* Add TODO notice for vote test utils to be fixtures
* Update asset model documentation to reflect usage of transaction id
* Fix outdated asset description in transaction schema
* Remove unnecessary import of rethinkdb in a test
* Move test_run_query_util as a rethinkdb-specific test
* Move rethinkdb-specific command tests to own file
* Add __init__.py to new test folders
* Move command tests to their own test module
* Move fixtures out of command tests into separate conftest for commands
* Fix some small flake8 issues with rethinkdb's test_run_query_util
* Add pytest ignore hook to filter out test dirs that are not for the requested backend
* Move backend-specific tests in tests/db/ to tests/backend/
