The information on that page was either wrong or redundant, so I either deleted it or linked to where to find the same information in the docs about contributing to BigchainDB.
* Problem: No good way to check for val set absence.
Solution: Make get_validator_set/get_validators return None/[] when there are no validators yet.
* Problem: Incompatible ABCI chain upgrades.
Solution: Record known chains and sync through InitChain. Triggering the migration and adjusting other ABCI endpoints will follow.
Solution: Election ID has to be unique but not every validator set record has it. MongoDB does not support partial indexes, does not even allow for multiple Nones. This is a temporary fix since we are introducing an `election` collection to store election IDs in #2498.
* Problem: cyrptoconditions dependency updated because of vulnerability CVE-2018-10903
* update cc to ~=0.7.2
* Fix test using b58encode
* Fixing some more tests failing because of base58 update
Solution: Remove un-necessary code. Deployment of MongoDB with or without replicaSet should be the responsibility of MongoDB admin which can and cannot be a BigchainDB node operator. As far as BigchainDB is concerned replicaset, if provided in bigchaindb configs, should be used to establish connection with MongoDB.
* Problem: We need to store the `election_id` as part of the `validator_update` so we can efficiently check which election was resposible for the change
Solution: Added the parameter to `store_validator_set` and aligned the tests
* Problem: Logic for `upsert-validator show` is convoluted
Solution: Rewrote the function to be much simpler
* Problem: Need a uniqueness constraint for election_id wrt validator changes
Solution: Added a new key to the db schema
Solution: BigchainDB by default writes logs in the same directory it is
run. The `looponfail` feature provided by pytest waits for changes in
the current directory, so it is continuously triggered. This patch tells
pytest to only watch the `bigchaindb` and `tests` directories.
Solution: if a TRANSFER transaction is validated after a CREATE
transaction, the system crashes with `AttributeError: 'NoneType' object
has no attribute 'txid'`.
This happens because querying `get_spent` checks the attributes `txid`
and `output` of `input.fulfills` for every transaction in the current
buffer (`current_transactions`). For a CREATE, `input.fulfills` is None,
so the check would fail.
The solution is to check if `input.fulfills` is defined. If not, then
the current transaction cannot spend any output, so we can safely skip
it.
Solution: Transfer vote to the election public key; generalize implemenation to handle election txn type
* Problem: Upsert valdiator 'new' doesn't accept public in base64 format
Solution: Tendermint stores all keys in base64 format so it would suitable to
abandon base58 encoding in favour of base64 encoding
* Problem: Not test for invalid execution of upsert-validator 'new'
Solution: Write tests to when invalid power or private key path has been supplied
* Problem: Exceptions are not informational when executing upsert-validator
Solution: generate error logs or print statement indicating success
Solution: have a more general approach to process transaction types. If
a transaction does *not* contain `asset.id`, then the `id` of the
`asset` is the `id` of the transaction.
* Problem: `run_upsert_validator_approve` was getting the voting power in a convoluted way
Solution: Changed it to get the voting power from the election outputs
* Problem: `run_upsert_validator_approve` casts votes for *all* voters, not just the user calling the command
Solution: Filter vote txs by the users public key
* Problem: Docs needed a more specific description of how to input the path to the private-key file
Solution: Changed the wording a bit
* Problem: several tests are skipped
Solution: activate or remove tests
* Problem: store_transaction is deprecated
Solution: replace it with store_bulk_transaction
* Problem: we don't test the transaction split
Solution: undelete `test_store_transaction`
* Problem: failing tests
Solution: merge master and change deprecated store_transaction
* Problem: tests in test_bigchain_api are not activated
Solution: remove or active tests
* Problem: TransactionNotInValidBlock was removed
Solution: remove TransactionNotInValidBlock from tests
