* added last_tx switch to the TX get query to only get the latest TX for a given asset.
* extended test case to contain last_tx field
* Add last_tx option in query module
* Fix natural descending cursor sort argument
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
* 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: HTTP info endpoints don't include "blocks"
Solution: Add "blocks" to the response to the HTTP info endpoints
* Removed "blocks" endpoints from "Advanced Usage"
because they are really not that advanced
* Problem: We need a way to synchronize a halt to block production to allow for upgrades across breaking changes.
* Solution: Created `MigrationElection`.
* Problem: Need documentation for `migration` elections.
* Solution: Updated the docs.
* Problem: `MigrationElection` needs 'new' CLI method.
* Solution: Updated the definition of `election` to include the new `migration` type.
* Problem: The way `end_block` checks for concluded elections assumes there is only one type of election (so we can't conclude an `upsert-validator` and a `chain-migration` at the same height).
* Solution: Re-engineered the code in `Elections` to conclude multiple elections in the same block. If more than one election change the validator set, only one of them is applied.
* Problem: Tendermint change to store validator changes at height h+2 will break `Election.get_status`.
* Solution: Reworked `get_validator_change` to look at only the latest block height or less.
- Hard-wire the supported Tendermint version(s) right in the code of BigchainDB Server. Check the version of Tendermint and disconnect if Tendermint version is an unsupported one.
- Expose a CLI command bigchaindb tendermint-version to display the supported Tendermint versions.
- PR also takes care the long list of warnings we get when we run tests.
- Updated deprecated pymongo methods
- Do not call pytest fixtures directly.
- Also added the doc for the new cli command
Solution: Stop getting events from the Tendermint events API. Get the
event right before returning from the COMMIT phase of Tendermint, and
publish it to the events queue.
* Problem: `ValidatorElection` and `MigrationElection` need to inherit from a common `Election` class
Solution: Factored the common logic out of `ValidatorElection` and moved it to `Election` parent class
* Problem: Adding base58 as a requirement seems to break the build...
Solution: Reverting the changes
* Problem: Responding to a suggestion for improved method naming
Solution: Refactored `get_result_by_election_id` to `get_election_result_by_id`
* Problem: No need to store different types of elections in their own tables
Solution: Remove `DB_TABLE` property from `Election` class
* Revert "Problem: No need to store different types of elections in their own tables"
This reverts commit db45374d3c.
* Problem: Missed a method in `Bigchain` class when updating the naming for an election method
Solution: Finished the refactoring
* Problem: Need a table to store data for all elections
Solution: Created the `elections` table with secondary_index `election_id`
* Problem: `Election` class needs to be updated to store concluded elections in the `elections` table
Solution: Updated the class to use the new table
* Problem: `UpsertValidatorVote` can be generalized to just be `Vote`
Solution: Renamed, refactored and moved the `Vote` class to tie in with the more general `Election` base class
* Problem: Error in docstring return signature
Solution: Fixed the docstring
* Problem: Hardcoded reference to the `VOTE_TYPE` in `Election` base class
Solution: Pointed the reference to the class variable
* Problem: Schema still refers to `ValidatorElectionVote` instead of `Vote`
Solution: Renamed `TX_SCHEMA_VALIDATOR_ELECTION_VOTE` as `TX_SCHEMA_VOTE`
* Problem: `Election` class variable `ELECTION_TYPE` is overly specific
Solution: Renamed `ELECTION_TYPE` to `OPERATION`
* Problem: Command line options for `upsert-validator` can be generalized to manage any type of election
Solution: Refactored the CLI to manage generalized elections
* Problem: Default for `show_election` not implemented for `Election` class
Solution: Create a default method that work if all fields in the 'asset[data]' can be displayed without additional formatting
* Problem: Multiple small issues with style etc.
Solution: Addressed comments from PR
* Problem: `Election` class variable to `VOTE_TYPE` unnecessary
Solution: Removed the variable and hardcoded everything to use the `Vote` class
* Problem: Minor style issues with PR
Solution: Addressing comments
* Problem: Changes to format for validator keys broke some tests
Solution: Aligned the tests to reflect the changed key format
* Problem: `election show` command displaying the base56 public key
Solution: Cast any public key to base64
* Problem: `election_parser` help message still refers to upsert-validator
Solution: Updated the help message
* Log rotation for tendermint and BigchainDB using Monit
* Change file size from 100KB used for testing to 200 MB for test envs
* Add docs for log rotation
* remove --consensus.create_empty_blocks from monit start
Because already taken care of in the config file
* do not run bigchaindb with debug flag instead use config file
* Address comments I
- Rephrase log rotation to imply monit is not default
- Add statement to explain where bigchaindb log files are created
- Fix HTML comment
- Add log rotation to index
* Address comments II
Solution: Change the docs to recommend installing a specific Tendermint version.
Also update our release process so we change that version number before a release, if necessary.
Solution: Document when the transactions posted in the async and sync modes can be lost. Describe how they are stored. Mention that BigchainDB does not store or expose rejected transactions.
