### Known Issues
|
||||
|
||||
Tendermint changed how it responds to a request to store data (via the [Tendermint Broadcast API](http://tendermint.readthedocs.io/projects/tools/en/master/using-tendermint.html#broadcast-api)) between version 0.12 and 0.19.2. We started modifying the code of BigchainDB Server to account for those changes in responses (in [pull request #2239](https://github.com/bigchaindb/bigchaindb/pull/2239)), but we found that there's a difference between what the Tendermint documentation _says_ about those responses and how Tendermint actually responds. We need to determine Tendermint's intent before we can finalize that pull request.

|

We use the phrase "BigchainDB consortium" (or just "consortium") to refer to the set of people and/or organizations who run the nodes of a BigchainDB network. A consortium requires some form of governance to make decisions such as membership and policies. The exact details of the governance process are determined by each consortium, but it can be very decentralized.
|
||||
|
||||
If sharding is turned on (i.e. if the number of shards is larger than one), then the actual data is decentralized in that no one node stores all the data.
|
||||
|
||||
Every node has its own locally-stored list of the public keys of other consortium members: the so-called keyring. There's no centrally-stored or centrally-shared keyring.
|
||||
|
||||
A consortium can increase its decentralization (and its resilience) by increasing its jurisdictional diversity, geographic diversity, and other kinds of diversity. This idea is expanded upon in [the section on node diversity](diversity.html).
|
||||
|
||||
There’s no node that has a long-term special position in the BigchainDB network. All nodes run the same software and perform the same duties.
|
||||
|
||||
If someone has (or gets) admin access to a node, they can mess with that node (e.g. change or delete data stored on that node), but those changes should remain isolated to that node. The BigchainDB network can only be compromised if more than one third of the nodes get compromised. See the [Tendermint documentation](https://tendermint.readthedocs.io/projects/tools/en/master/introduction.html) for more details.

See the [Tendermint documentation](https://tendermint.com/docs/introduction/introduction.html) for more details.
|
||||
|
||||
It’s worth noting that not even the admin or superuser of a node can transfer assets. The only way to create a valid transfer transaction is to fulfill the current crypto-conditions on the asset, and the admin/superuser can’t do that because the admin user doesn’t have the necessary information (e.g. private keys).

@ -8,16 +8,8 @@ BigchainDB and Smart Contracts
|
||||
|
||||
One can store the source code of any smart contract (i.e. a computer program) in BigchainDB, but BigchainDB won't run arbitrary smart contracts.
|
||||
|
||||
BigchainDB will run the subset of smart contracts expressible using `Crypto-Conditions <https://tools.ietf.org/html/draft-thomas-crypto-conditions-03>`_.
|
||||
BigchainDB can be used to enforce who has permission to transfer assets, both fungible assets and non-fungible assets. It will prevent double-spending. In other words, a BigchainDB network could be used instead of an ERC-20 (fungible token) or ERC-721 (non-fungible token) smart contract.
|
||||
|
||||
The owners of an asset can impose conditions on it that must be met for the asset to be transferred to new owners. Examples of possible conditions (crypto-conditions) include:
|
||||
Asset transfer permissions can also be interpreted as write permissions, so they can be used to control who can write to a log, journal or audit trail. There is more about that idea in :ref:`the page about permissions in BigchainDB <permissions-in-bigchaindb>`.
|
||||
|
||||
- The current owner must sign the transfer transaction (one which transfers ownership to new owners).
|
||||
- Three out of five current owners must sign the transfer transaction.
|
||||
- (Shannon and Kelly) or Morgan must sign the transfer transaction.
|
||||
|
||||
Crypto-conditions can be quite complex. They can't include loops or recursion and therefore will always run/check in finite time.
|
||||
|
||||
.. note::
|
||||
|
||||
We used the word "owners" somewhat loosely above. A more accurate word might be fulfillers, signers, controllers, or transfer-enablers. See the section titled **A Note about Owners** in the relevant `BigchainDB Transactions Spec <https://github.com/bigchaindb/BEPs/tree/master/tx-specs/>`_.
|
||||
A BigchainDB network can be connected to other blockchain networks, via oracles or inter-chain communications protocols. That means BigchainDB can be used as part of a solution that uses *other* blockchains to run arbitrary smart contracts.

|
||||
**This is an experimental feature. Users are advised not to use it in production.**
|
||||
|
||||
|
||||
Manage elections to add, update, or remove a validator from the validators set of the local node. The upsert-validator subcommands implement [BEP-21](https://github.com/bigchaindb/BEPs/tree/master/21). Check it out if you need more details on how this is orchestrated.
|
||||
Manage elections to add, update, or remove a validator from the validators set. The upsert-validator subcommands implement [BEP-21](https://github.com/bigchaindb/BEPs/tree/master/21), please refer it for more details.
|
||||
|
||||
Election management is broken into several subcommands. Below is the command line syntax for each,
|
||||
|
||||
#### upsert-validator new
|
||||
|
||||
Calls a new election, proposing a change to the validator set.
|
||||
Create a new election which proposes a change to the validator set. An election can be used to add/update/remove a validator from the validator set.
|
||||
|
||||
Below is the command line syntax and the return value,
|
||||
|
||||
```bash
|
||||
$ bigchaindb upsert-validator new E_PUBKEY E_POWER E_NODE_ID --private-key PATH_TO_YOUR_PRIVATE_KEY
|
||||
<election_id>
|
||||
[SUCCESS] Submitted proposal with id: <election_id>
|
||||
```
|
||||
|
||||
Here, `E_PUBKEY`, `E_POWER`, and `E_NODE_ID` are the public key, proposed power, and node id of the validator being voted on. `--private-key` should be the path to wherever the private key for your validator node is stored, (*not* the private key itself.). For example, to add a new validator, provide the public key and node id for some node not already in the validator set, along with whatever voting power you'd like them to have. To remove an existing validator, provide their public key and node id, and set `E_POWER` to `0`.
|
||||
- `E_PUBKEY`: Public key of the node to be added/updated/removed.
|
||||
- `E_POWER`: The new power for the `E_PUBKEY`. NOTE, if power is set to `0` then `E_PUBKEY` will be removed from the validator set when the election concludes.
|
||||
- `E_NODE_ID`: Node id of `E_PUBKEY`. The node operator of `E_PUBKEY` can generate the node id via `tendermint show_node_id`.
|
||||
- `--private-key`: The path to Tendermint's private key which can be generally found at `/home/user/.tendermint/config/priv_validator.json`. For example, to add a new validator, provide the public key and node id for some node not already in the validator set, along with whatever voting power you'd like them to have. To remove an existing validator, provide their public key and node id, and set `E_POWER` to `0`. Please note that the private key provided here is of the node which is generating this election i.e.
|
||||
|
||||
|
||||
NOTE: A change to the validator set can only be proposed by one of the exisitng validators.
|
||||
|
||||
Example usage,
|
||||
|
||||
```bash
|
||||
$ bigchaindb upsert-validator new B0E42D2589A455EAD339A035D6CE1C8C3E25863F268120AA0162AD7D003A4014 1 12345 --private-key /home/user/.tendermint/config/priv_validator.json
|
||||
$ bigchaindb upsert-validator new HHG0IQRybpT6nJMIWWFWhMczCLHt6xcm7eP52GnGuPY= 1 fb7140f03a4ffad899fabbbf655b97e0321add66 --private-key /home/user/.tendermint/config/priv_validator.json
|
||||
[SUCCESS] Submitted proposal with id: 04a067582cf03eba2b53b82e4adb5ece424474cbd4f7183780855a93ac5e3caa
|
||||
```
|
||||
|
||||
If the command succeeds, it will create an election and return an `election_id`. Elections consist of one vote token per voting power, issued to the members of the validator set. Validators can cast their votes to approve the change to the validator set by spending their vote tokens. The status of the election can be monitored by providing the `election_id` to the `show` subcommand.
|
||||
If the command succeeds, it will create an election and return an `election_id`. A successful execution of the above command **doesn't** imply that the validator set will be immediately updated but rather it means the proposal has been succcessfully accepted by the network. Once the `election_id` has been generated the node operator should share this `election_id` with other validators in the network and urge them to approve the proposal. Note that the node operator should themsleves also approve the proposal.
|
||||
|
||||
|
||||
**NOTE**: The election proposal consists of vote tokens allocated to each current validator as per their voting power. Validators then cast their votes to approve the change to the validator set by spending their vote tokens.
|
||||
|
||||
|
||||
#### upsert-validator approve
|
||||
Approve an election by voting for it.
|
||||
Below is the command line syntax and the return value,
|
||||
|
||||
Approve an election by voting for it. The propsal generated by executing `bigchaindb upsert-valdiator approve ...` can approved by the validators using this command. The validator who is approving the proposal will spend all their votes i.e. if the validator has a network power of `10` then they will cast `10` votes for the proposal.`
|
||||
Below is the command line syntax and the return value,
|
||||
|
||||
```bash
|
||||
$ bigchaindb upsert-validator approve <election_id> --private-key PATH_TO_YOUR_PRIVATE_KEY
|
||||
[SUCCESS] Your vote has been submitted
|
||||
```
|
||||
Here, `<election_id>` is the transaction id of the election the approval should be given for. `--private-key` should be the path to Tendermint's private key which can be generally found at `/home/user/.tendermint/config/priv_validator.json`.
|
||||
|
||||
- `election_id` is the transaction id of the election the approval should be given for.
|
||||
- `--private-key` should be the path to Tendermint's private key which can be generally found at `/home/user/.tendermint/config/priv_validator.json`.
|
||||
|
||||
Example usage,
|
||||
```bash
|
||||
$ bigchaindb upsert-validator approve 04a067582cf03eba2b53b82e4adb5ece424474cbd4f7183780855a93ac5e3caa --private-key /home/user/.tendermint/config/priv_validator.json
|
||||
[SUCCESS] Your vote has been submitted
|
||||
```
|
||||
If the command succeeds, a message will be returned, that the vote was submitted successfully.
|
||||
|
||||
If the command succeeds a message will be returned stating that the vote was submitted successfully. Once a proposal has been approved by sufficent validators (more than `2/3` of the total voting power) then the proposed change is applied to the network. For example, consider a network wherein the total power is `90` then the proposed changed applied only after `60` (`2/3 * 90`) have been received.
|
||||
|
||||
#### upsert-validator show
|
||||
|
||||
Retrieves information about an election initiated by `upsert-validator new`.
|
||||
|
||||
Below is the command line syntax and the return value,
|
||||
|
||||
```bash
|
||||
$ bigchaindb upsert-validator show ELECTION_ID
|
||||
public_key=<e_pub_key>
|
||||
power=<e_power>
|
||||
node_id=<e_node_id>
|
||||
status=<status>
|
||||
```
|
||||
|
||||
The `public_key`, `power`, and `node_id` are the same values used in the `upsert-validator new` command that originally triggered the election. `status` takes three possible values, `ongoing`, if the election has not yet reached a 2/3 majority, `concluded`, if the election reached the 2/3 majority needed to pass, or `inconclusive`, if the validator set changed while the election was in process, rendering it undecidable.

* `database.replicaset` is the name of the MongoDB replica set. The default value is `null` because in BighainDB 2.0+, each BigchainDB node has its own independent MongoDB database and no replica set is necessary.
|
||||
* `database.login` and `database.password` are the login and password used to authenticate to the backend database, specified in plaintext.
|
||||
* `database.ssl` determines if BigchainDB connects to MongoDB over TLS/SSL or not. It can be set to `true` or `false`.
|
||||
* `database.replicaset` is the name of the MongoDB replica set. The default value is `null` because in BigchainDB 2.0+, each BigchainDB node has its own independent MongoDB database and no replica set is necessary. Replica set must already exist if this option is configured, BigchainDB will not create it.
|
||||
* `database.ssl` must be `true` or `false`. It tells BigchainDB Server whether it should connect to MongoDB using TLS/SSL or not. The default value is `false`.
|
||||
|
||||
There are three ways for BigchainDB Server to authenticate itself with MongoDB (or a specific MongoDB database): no authentication, username/password, and x.509 certificate authentication.
|
||||
|
||||
**No Authentication**
|
||||
|
||||
If you use all the default BigchainDB configuration settings, then no authentication will be used.
|
||||
|
||||
**Username/Password Authentication**
|
||||
|
||||
To use username/password authentication, a MongoDB instance must already be running somewhere (maybe in another machine), it must already have a database for use by BigchainDB (usually named `bigchain`, which is the default `database.name`), and that database must already have a "readWrite" user with associated username and password. To create such a user, login to your MongoDB instance as Admin and run the following commands:
|
||||
|
||||
```text
|
||||
use <database.name>
|
||||
db.createUser({user: "<database.login>", pwd: "<database.password>", roles: [{role: "readWrite", db: "<database.name>"}]})
|
||||
```
|
||||
|
||||
* `database.login` is the user's username.
|
||||
* `database.password` is the user's password, given in plaintext.
|
||||
* `database.ca_cert`, `database.certfile`, `database.keyfile`, `database.crlfile`, and `database.keyfile_passphrase` are not used so they can have their default values.
|
||||
|
||||
**x.509 Certificate Authentication**
|
||||
|
||||
To use x.509 certificate authentication, a MongoDB instance must be running somewhere (maybe in another machine), it must already have a database for use by BigchainDB (usually named `bigchain`, which is the default `database.name`), and that database must be set up to use x.509 authentication. See the MongoDB docs about how to do that.
|
||||
|
||||
* `database.login` is the user's username.
|
||||
* `database.password` isn't used so the default value (`null`) is fine.
|
||||
* `database.ca_cert`, `database.certfile`, `database.keyfile` and `database.crlfile` are the paths to the CA, signed certificate, private key and certificate revocation list files respectively.
|
||||
* `database.keyfile_passphrase` is the private key decryption passphrase, specified in plaintext.

## Problem Description
|
||||
When posting a transaction it is broadcast asynchronously to Tendermint which enables the client to return immediately. Furthermore, the transaction status API would allow the client to get the current status for a given transaction. The above workflow seems efficient when the client doesn't need to wait until a transaction gets committed. In case a client wishes to wait until a transaction gets committed it would need to poll the transaction status api.
|
||||
The Tendermint api allows to post a transaction in [three modes](http://tendermint.readthedocs.io/projects/tools/en/master/using-tendermint.html#broadcast-api),

## The tests/ Folder
|
||||
Most of the tests in the `tests/` folder are unit tests. For info about how to write and run tests, see [the docs about contributing to BigchainDB](http://docs.bigchaindb.com/projects/contributing/en/latest/index.html), especially:
|
||||
|
||||
The `tests/` folder is where all the tests for BigchainDB Server live. Most of them are unit tests. Integration tests are in the [`tests/integration/` folder](./integration/).

|
||||
A few notes:
|
||||
|
||||
- [`tests/common/`](./common/) contains self-contained tests only testing
|
||||
[`bigchaindb/common/`](../bigchaindb/common/)
|
||||
- [`tests/backend/`](./backend/) contains tests requiring
|
||||
the database backend (MongoDB)
|
||||
|
||||
|
||||
## Writing Tests
|
||||
|
||||
We write unit and integration tests for our Python code using the [pytest](http://pytest.org/latest/) framework. You can use the tests in the `tests/` folder as templates or examples.
|
||||
|
||||
|
||||
## Running Tests
|
||||
|
||||
### Running Tests Directly
|
||||
|
||||
If you installed BigchainDB Server using `pip install bigchaindb`, then you
|
||||
didn't install the tests. Before you can run all the tests, you must install
|
||||
BigchainDB from source. The [`CONTRIBUTING.md` file](../CONTRIBUTING.md) has
|
||||
instructions for how to do that.
|
||||
|
||||
Next, make sure you have Local MongoDB running in the background. You
|
||||
can run MongoDB using `mongod`.
|
||||
|
||||
The `pytest` command has many options. If you want to learn about all the
|
||||
things you can do with pytest, see [the pytest
|
||||
documentation](http://pytest.org/latest/). We've also added a customization to
|
||||
pytest:
|
||||
|
||||
`--database-backend`: Defines the backend to use for the tests. It defaults to
|
||||
`localmongodb`.
|
||||
|
||||
Now you can run all tests using:
|
||||
```text
|
||||
pytest -v
|
||||
```
|
||||
|
||||
or, if that doesn't work, try:
|
||||
```text
|
||||
python -m pytest -v
|
||||
```
|
||||
|
||||
or:
|
||||
```text
|
||||
python setup.py test
|
||||
```
|
||||
|
||||
How does `python setup.py test` work? The documentation for [pytest-runner](https://pypi.python.org/pypi/pytest-runner) explains.
|
||||
|
||||
The `pytest` command has many options. If you want to learn about all the things you can do with pytest, see [the pytest documentation](http://pytest.org/latest/). We've also added a customization to pytest:
|
||||
|
||||
|
||||
### Running Tests with Docker Compose
|
||||
|
||||
You can also use [Docker Compose](https://docs.docker.com/compose/) to run all the tests.
|
||||
|
||||
First, bring up all the services BigchainDB, MongoDB, Tendermint in the background:
|
||||
|
||||
```text
|
||||
$ docker-compose up -d bdb
|
||||
```
|
||||
|
||||
then run the tests using:
|
||||
|
||||
```text
|
||||
$ docker-compose run --rm --no-deps bigchaindb pytest -v
|
||||
```
|
||||
|
||||
## Automated Testing of All Pull Requests
|
||||
|
||||
We use [Travis CI](https://travis-ci.com/), so that whenever someone creates a new BigchainDB pull request on GitHub, Travis CI gets the new code and does _a bunch of stuff_. We use the same `docker-compose.yml` for tests. It tells Travis CI how to install BigchainDB, how to run all the tests, and what to do "after success" (e.g. run `codecov`). (We use [Codecov](https://codecov.io/) to get a rough estimate of our test coverage.)
|
||||
|
||||
|
||||
### Tox
|
||||
|
||||
We use [tox](https://tox.readthedocs.io/en/latest/) to run multiple suites of tests against multiple environments during automated testing. Generally you don't need to run this yourself, but it might be useful when troubleshooting a failing Travis CI build.
|
||||
|
||||
To run all the tox tests, use:
|
||||
```text
|
||||
tox
|
||||
```
|
||||
|
||||
or:
|
||||
```text
|
||||
python -m tox
|
||||
```
|
||||
|
||||
To run only a few environments, use the `-e` flag:
|
||||
```text
|
||||
tox -e {ENVLIST}
|
||||
```
|
||||
|
||||
where `{ENVLIST}` is one or more of the environments specified in the [tox.ini file](../tox.ini).
|
||||
Note: There are acceptance tests in the `acceptance/` folder (at the same level in the hierarchy as the `tests/` folder).
