Changelog

0.6.1 (June 28, 2017)

Make lots of small cli fixes that arose when people were using the tools for the testnet.

IMPROVEMENTS:

  • basecoin
    • basecoin start supports all flags that tendermint node does, such as --rpc.laddr, --p2p.seeds, and --p2p.skip_upnp
    • fully supports --log_level and --trace for logger configuration
    • merkleeyes no longers spams the logs... unless you want it
      • Example: basecoin start --log_level="merkleeyes:info,state:info,*:error"
      • Example: basecoin start --log_level="merkleeyes:debug,state:info,*:error"
  • basecli
    • basecli init is more intelligent and only complains if there really was a connected chain, not just random files
    • support localhost:46657 or http://localhost:46657 format for nodes, not just tcp://localhost:46657
    • Add --genesis to init to specify chain-id and validator hash
      • Example: basecli init --node=localhost:46657 --genesis=$HOME/.basecoin/genesis.json
    • basecli rpc has a number of methods to easily accept tendermint rpc, and verifies what it can

BUG FIXES:

  • basecli
    • basecli query account accepts hex account address with or without 0x prefix
    • gives error message when running commands on an unitialized chain, rather than some unintelligable panic

0.6.0 (June 22, 2017)

Make the basecli command the only way to use client-side, to enforce best security practices. Lots of enhancements to get it up to production quality.

BREAKING CHANGES:

  • ./cmd/commands -> ./cmd/basecoin/commands
  • basecli
    • basecli proof state get -> basecli query key
    • basecli proof tx get -> basecli query tx
    • basecli proof state get --app=account -> basecli query account
    • use --chain-id not --chainid for consistency
    • update to use --trace not --debug for stack traces on errors
    • complete overhaul on how tx and query subcommands are added. (see counter or trackomatron for examples)
    • no longer supports counter app (see new countercli)
  • basecoin
    • basecoin init takes an argument, an address to allocate funds to in the genesis
    • removed key2.json
    • removed all client side functionality from it (use basecli now for proofs)
      • no tx subcommand
      • no query subcommand
      • no account (query) subcommand
      • a few other random ones...
    • enhanced relay subcommand
      • relay start did what relay used to do
      • relay init registers both chains on one another (to set it up so relay start just works)
  • docs
    • removed example-plugin, put counter inside docs/guide
  • app
    • Implements ABCI handshake by proxying merkleeyes.Info()

IMPROVEMENTS:

  • basecoin init support --chain-id
  • intergrates tendermint 0.10.0 (not the rc-2, but the real thing)
  • commands return error code (1) on failure for easier script testing
  • add reset_all to basecli, and never delete keys on init
  • new shutil based unit tests, with better coverage of the cli actions
  • just make fresh when things are getting stale ;)

BUG FIXES:

  • app: no longer panics on missing app_options in genesis (thanks, anton)
  • docs: updated all docs... again
  • ibc: fix panic on getting BlockID from commit without 100% precommits (still a TODO)

0.5.2 (June 2, 2017)

BUG FIXES:

  • fix parsing of the log level from Tendermint config (#97)

0.5.1 (May 30, 2017)

BUG FIXES:

  • fix ibc demo app to use proper tendermint flags, 0.10.0-rc2 compatibility
  • Make sure all cli uses new json.Marshal not wire.JSONBytes

0.5.0 (May 27, 2017)

BREAKING CHANGES:

  • only those related to the tendermint 0.9 -> 0.10 upgrade

IMPROVEMENTS:

  • basecoin cli
    • integrates tendermint 0.10.0 and unifies cli (init, unsafe_reset_all, ...)
    • integrate viper, all command line flags can also be defined in environmental variables or config.toml
  • genesis file
    • you can define accounts with either address or pub_key
    • sorts coins for you, so no silent errors if not in alphabetical order
  • light-client integration
    • no longer must you trust the node you connect to, prove everything!
    • new basecli command
    • integrated key management, stored encrypted locally
    • tracks validator set changes and proves everything from one initial validator seed
    • basecli proof state gets complete proofs for any abci state
    • basecli proof tx gets complete proof where a tx was stored in the chain
    • basecli proxy exposes tendermint rpc, but only passes through results after doing complete verification

BUG FIXES:

  • no more silently ignored error with invalid coin names (eg. "17.22foo coin" used to parse as "17 foo", not warning/error)

0.4.1 (April 26, 2017)

BUG FIXES:

  • Fix bug in basecoin unsafe_reset_X where the priv_validator.json was not being reset

0.4.0 (April 21, 2017)

BREAKING CHANGES:

  • CLI now uses Cobra, which forced changes to some of the flag names and orderings

IMPROVEMENTS:

  • basecoin init doesn't generate error if already initialized
  • Much more testing

0.3.1 (March 23, 2017)

IMPROVEMENTS:

  • CLI returns exit code 1 and logs error before exiting

0.3.0 (March 23, 2017)

BREAKING CHANGES:

  • Remove --data flag and use BCHOME to set the home directory (defaults to ~/.basecoin)
  • Remove --in-proc flag and start Tendermint in-process by default (expect Tendermint files in $BCHOME/tendermint). To start just the ABCI app/server, use basecoin start --without-tendermint.
  • Consolidate genesis files so the Basecoin genesis is an object under app_options in Tendermint genesis. For instance:
{
  "app_hash": "",
  "chain_id": "foo_bar_chain",
  "genesis_time": "0001-01-01T00:00:00.000Z",
  "validators": [
    {
      "amount": 10,
      "name": "",
      "pub_key": [
	1,
	"7B90EA87E7DC0C7145C8C48C08992BE271C7234134343E8A8E8008E617DE7B30"
      ]
    }
  ],
  "app_options": {
    "accounts": [{
      "pub_key": {
        "type": "ed25519",
        "data": "6880db93598e283a67c4d88fc67a8858aa2de70f713fe94a5109e29c137100c2"
      },
      "coins": [
        {
          "denom": "blank",
          "amount": 12345
        },
        {
          "denom": "ETH",
          "amount": 654321
        }
      ]
    }],
    "plugin_options": ["plugin1/key1", "value1", "plugin1/key2", "value2"]
  }
}

Note the array of key-value pairs is now under app_options.plugin_options while the app_options themselves are well formed. We also changed chainID to chain_id and consolidated to have just one of them.

  • Introduce basecoin init and basecoin unsafe_reset_all
