Changelog

Unreleased

State Machine Breaking

(genesis) #5017 The x/genaccounts module has been deprecated and all components removed except the legacy/ package. This requires changes to the genesis state. Namely, accounts now exist under app_state.auth.accounts. The corresponding migration logic has been implemented for v0.38 target version. Applications can migrate via: $ {appd} migrate v0.38 genesis.json.

API Breaking Changes

(store) #4748 The CommitMultiStore interface now requires a SetInterBlockCache method. Applications that do not wish to support this can simply have this method perform a no-op.
(modules) #4665 Refactored x/gov module structure and dev-UX:
- Prepare for module spec integration
- Update gov keys to use big endian encoding instead of little endian
(modules) #5017 The x/genaccounts module has been deprecated and all components removed except the legacy/ package.

Client Breaking Changes

(rest) #4783 The balance field in the DelegationResponse type is now sdk.Coin instead of sdk.Int

Features

(store) #4724 Multistore supports substore migrations upon load. New rootmulti.Store.LoadLatestVersionAndUpgrade method in Baseapp supports StoreLoader to enable various upgrade strategies. It no longer panics if the store to load contains substores that we didn't explicitly mount.
#4972 A TxResponse with a corresponding code and tx hash will be returned for specific Tendermint errors:
- CodeTxInMempoolCache
- CodeMempoolIsFull
- CodeTxTooLarge
#3872 Implement a RESTful endpoint and cli command to decode transactions.
(keys) #4754 Introduce new Keybase implementation that can leverage operating systems' built-in functionalities to securely store secrets. MacOS users may encounter the following issue with the go-keychain library. If you encounter this issue, you must upgrade your xcode command line tools to version >= 10.2. You can upgrade via: sudo rm -rf /Library/Developer/CommandLineTools; xcode-select --install. Verify the correct version via: pkgutil --pkg-info=com.apple.pkg.CLTools_Executables.
(keys) #5097 New keys migrate command to assist users migrate their keys to the new keyring.

Improvements

(server) #4215 The --pruning flag has been moved to the configuration file, to allow easier node configuration.

(cli) #5116 The CLIContext now supports multiple verifiers when connecting to multiple chains. The connecting chain's CLIContext will have to have the correct chain ID and node URI or client set. To use a CLIContext with a verifier for another chain:

// main or parent chain (chain as if you're running without IBC)
mainCtx := context.NewCLIContext()

// connecting IBC chain
sideCtx := context.NewCLIContext().
  WithChainID(sideChainID).
  WithNodeURI(sideChainNodeURI) // or .WithClient(...)

sideCtx = sideCtx.WithVerifier(
  context.CreateVerifier(sideCtx, context.DefaultVerifierCacheSize),
)

(modules) #5017 The x/auth package now supports generalized genesis accounts through the GenesisAccount interface.
(modules) #4762 Deprecate remove and add permissions in ModuleAccount.
(modules) #4760 update x/auth to match module spec.
(modules) #4814 Add security contact to Validator description.
(modules) #4875 refactor integration tests to use SimApp and separate test package
(sdk) #4566 Export simulation's parameters and app state to JSON in order to reproduce bugs and invariants.
(sdk) #4640 improve import/export simulation errors by extending DiffKVStores to return an array of KVPairs that are then compared to check for inconsistencies.
(sdk) #4717 refactor x/slashing to match the new module spec
(sdk) #4758 update x/genaccounts to match module spec
(simulation) #4824 PrintAllInvariants flag will print all failed invariants

- Add RandomizedParams to the SimulationManager that registers each modules' parameters Content to simulate ParamChangeProposals
(simulation) #4893 Change SimApp keepers to be public and add getter functions for keys and codec
(simulation) #4906 Add simulation Config struct that wraps simulation flags
(store) #4792 panic on non-registered store
(types) #4821 types/errors package added with support for stacktraces. It is meant as a more feature-rich replacement for sdk.Errors in the mid-term.
(store) #1947 Implement inter-block (persistent) caching through CommitKVStoreCacheManager. Any application wishing to utilize an inter-block cache must set it in their app via a BaseApp option. The BaseApp docs have been drastically improved to detail this new feature and how state transitions occur.
(docs/spec) All module specs moved into their respective module dir in x/ (i.e. docs/spec/staking -->> x/staking/spec)

v0.36.0 - 2019-08-13

Breaking Changes

(rest) #4837 Remove /version and /node_version endpoints in favor of refactoring /node_info to also include application version info.

#4159 create the default module patterns and module manager
#4230 Change the type of ABCIMessageLog#MsgIndex to uint16 for proper serialization.
#4250 BaseApp.Query() returns app's version string set via BaseApp.SetAppVersion() when handling /app/version queries instead of the version string passed as build flag at compile time.
#4262 GoSumHash is no longer returned by the version command.
#4263 RestServer#Start now takes read and write timeout arguments.
#4305 GenerateOrBroadcastMsgs no longer takes an offline parameter.
#4342 Upgrade go-amino to v0.15.0
#4351 InitCmd, AddGenesisAccountCmd, and CollectGenTxsCmd take node's and client's default home directories as arguments.
#4387 Refactor the usage of tags (now called events) to reflect the new ABCI events semantics:
- Move x/{module}/tags/tags.go => x/{module}/types/events.go
- Update docs/specs
- Refactor tags in favor of new Event(s) type(s)
- Update Context to use new EventManager
- (Begin|End)Blocker no longer return tags, but rather uses new EventManager
- Message handlers no longer return tags, but rather uses new EventManager Any component (e.g. BeginBlocker, message handler, etc...) wishing to emit an event must do so through ctx.EventManger().EmitEvent(s). To reset or wipe emitted events: ctx = ctx.WithEventManager(sdk.NewEventManager()) To get all emitted events: events := ctx.EventManager().Events()
#4437 Replace governance module store keys to use []byte instead of string.
#4451 Improve modularization of clients and modules:
- Module directory structure improved and standardized
- Aliases autogenerated
- Auth and bank related commands are now mounted under the respective moduels
- Client initialization and mounting standardized
#4479 Remove codec argument redundency in client usage where the CLIContext's codec should be used instead.

#4521 Flatten x/bank structure by hiding module internals.
#4525 Remove --cors flag, the feature is long gone.
#4536 The /auth/accounts/{address} now returns a height in the response. The account is now nested under account.
#4543 Account getters are no longer part of client.CLIContext() and have now moved to reside in the auth-specific AccountRetriever.
#4588 Context does not depend on x/auth anymore. client/context is stripped out of the following features:
- GetAccountDecoder()
- CLIContext.WithAccountDecoder()
- CLIContext.WithAccountStore() x/auth.AccountDecoder is unnecessary and consequently removed.
#4602 client/input.{Buffer,Override}Stdin() functions are removed. Thanks to cobra's new release they are now redundant.
#4633 Update old Tx search by tags APIs to use new Events nomenclature.
#4649 Refactor x/crisis as per modules new specs.
#3685 The default signature verification gas logic (DefaultSigVerificationGasConsumer) now specifies explicit key types rather than string pattern matching. This means that zones that depended on string matching to allow other keys will need to write a custom SignatureVerificationGasConsumer function.
#4663 Refactor bank keeper by removing private functions
- InputOutputCoins, SetCoins, SubtractCoins and AddCoins are now part of the SendKeeper instead of the Keeper interface
(tendermint) #4721 Upgrade Tendermint to v0.32.1

Features

#4271 Implement Coins#IsAnyGT
#4318 Support height queries. Queries against nodes that have the queried height pruned will return an error.
#4409 Implement a command that migrates exported state from one version to the next. The migrate command currently supports migrating from v0.34 to v0.36 by implementing necessary types for both versions.
#4570 Move /bank/balances/{address} REST handler to x/bank/client/rest. The exposed interface is unchanged.
Community pool spend proposal per Cosmos Hub governance proposal #7 "Activate the Community Pool"

Improvements

#4194 ValidatorSigningInfo now includes the validator's consensus address.
#4235 Add parameter change proposal messages to simulation.
#4235 Update the minting module params to implement params.ParamSet so individual keys can be set via proposals instead of passing a struct.
#4259 Coins that are nil are now JSON encoded as an empty array []. Decoding remains unchanged and behavior is left intact.
#4305 The --generate-only CLI flag fully respects offline tx processing.
#4379 close db write batch.
#4384- Allow splitting withdrawal transaction in several chunks
#4403 Allow for parameter change proposals to supply only desired fields to be updated in objects instead of the entire object (only applies to values that are objects).
#4415 /client refactor, reduce genutil dependancy on staking
#4439 Implement governance module iterators.
#4465 Unknown subcommands print relevant error message
#4466 Commission validation added to validate basic of MsgCreateValidator by changing CommissionMsg to CommissionRates

#4629 Added warning event that gets emitted if validator misses a block.
#4674 Export Simapp genState generators and util functions by making them public
#4706 Simplify context Replace complex Context construct with a simpler immutible struct. Only breaking change is not to support Value and GetValue as first class calls. We do embed ctx.Context() as a raw context.Context instead to be used as you see fit.

Migration guide:
```
ctx = ctx.WithValue(contextKeyBadProposal, false)
```
Now becomes:
```
ctx = ctx.WithContext(context.WithValue(ctx.Context(), contextKeyBadProposal, false))
```
A bit more verbose, but also allows context.WithTimeout(), etc and only used in one function in this repo, in test code.
#3685 Add SetAddressVerifier and GetAddressVerifier to sdk.Config to allow SDK users to configure custom address format verification logic (to override the default limitation of 20-byte addresses).
#3685 Add an additional parameter to NewAnteHandler for a custom SignatureVerificationGasConsumer (the default logic is now in `DefaultSigVerificationGasConsumer). This allows SDK users to configure their own logic for which key types are accepted and how those key types consume gas.
Remove --print-response flag as it is no longer used.
Revert #2284 to allow create_empty_blocks in the config
(tendermint) #4718 Upgrade tendermint/iavl to v0.12.3

0.33.0

BREAKING CHANGES

Gaia REST API
- #3641 Remove the ability to use a Keybase from the REST API client:
  - password and generate_only have been removed from the base_req object
  - All txs that used to sign or use the Keybase now only generate the tx
  - keys routes completely removed
- #3692 Update tx encoding and broadcasting endpoints:
  - Remove duplicate broadcasting endpoints in favor of POST @ /txs
    - The Tx field now accepts a StdTx and not raw tx bytes
  - Move encoding endpoint to /txs/encode
Gaia
- #3787 Fork the x/bank module into the Gaia application with only a modified message handler, where the modified message handler behaves the same as the standard x/bank message handler except for MsgMultiSend that must burn exactly 9 atoms and transfer 1 atom, and MsgSend is disabled.
- #3789 Update validator creation flow:
  - Remove NewMsgCreateValidatorOnBehalfOf and corresponding business logic
  - Ensure the validator address equals the delegator address during MsgCreateValidator#ValidateBasic
SDK
- #3750 Track outstanding rewards per-validator instead of globally, and fix the main simulation issue, which was that slashes of re-delegations to a validator were not correctly accounted for in fee distribution when the redelegation in question had itself been slashed (from a fault committed by a different validator) in the same BeginBlock. Outstanding rewards are now available on a per-validator basis in REST.
- #3669 Ensure consistency in message naming, codec registration, and JSON tags.
- #3788 Change order of operations for greater accuracy when calculating delegation share token value

Updates for dependencies

0.7.1 (October 11, 2017)

IMPROVEMENTS:

server/commands: GetInitCmd takes list of options

0.7.0 (October 11, 2017)

BREAKING CHANGES:

Everything has changed, and it's all about to change again, so don't bother using it yet!

0.6.2 (July 27, 2017)

IMPROVEMENTS:

auto-test all tutorials to detect breaking changes
move deployment scripts from /scripts to /publish for clarity

BUG FIXES:

basecoin init ensures the address in genesis.json is valid
fix bug that certain addresses couldn't receive ibc packets

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.

FEATURES:

Introduce basecoin init and basecoin unsafe_reset_all

0.2.0 (March 6, 2017)

BREAKING CHANGES:

Update to ABCI v0.4.0 and Tendermint v0.9.0

FEATURES:

CLI for sending transactions and querying the state, designed to be easily extensible as plugins are implemented

Add /account path in Query
IBC plugin for InterBlockchain Communication
Demo script of IBC between two chains

IMPROVEMENTS:

Use new Tendermint /commit endpoint for crafting IBC transactions

Demo uses fewer sleeps

BUG FIXES:

Various little fixes in coin arithmetic
More commit validation in IBC
