## Description
Closes: #577
This pull request contains `Canceling unbonding delegation entry` and `delegate back to previous validator`
### `Msg` Service
```protobuf=
package cosmos.staking.v1beta1;
service Msg {
// CancelUnbondingDelegation
rpc CancelUnbondingDelegation(MsgCancelUnbondingDelegation) returns (MsgCancelUnbondingDelegationResponse);
}
// MsgCancelUnbondingDelegation
message MsgCancelUnbondingDelegation {
option (gogoproto.equal) = false;
option (gogoproto.goproto_getters) = false;
string delegator_address = 1 [(cosmos_proto.scalar) = "cosmos.AddressString"];
string validator_address = 2 [(cosmos_proto.scalar) = "cosmos.AddressString"];
cosmos.base.v1beta1.Coin amount = 3 [(gogoproto.nullable) = false];
// creation_height is the height which the unbonding took place.
int64 creation_height = 4;
}
// MsgCancelUnbondingDelegationResponse
message MsgCancelUnbondingDelegationResponse{
}
```
### `Msg` Method Implementation
```go=
func (k msgServer) CancelUnbondingDelegation(goCtx context.Context, msg *types.MsgCancelUnbondingDelegation) (*types.MsgCancelUnbondingDelegationResponse, error) {
/*
// checking the unbonding delegation at creation_height
// get the unbonding delegations of delegatorAddress
if ubdEntry balance is equal to msg.Amount
remove the entry from ubd
else
update the specific entry with new balance
if len(ubd.Entries) == 0 {
k.RemoveUnbondingDelegation(ctx, ubd)
} else {
k.SetUnbondingDelegation(ctx, ubd)
}
*/
// update the delegation back to validator
// get validator
validator, found := k.GetValidator(ctx, valAddr)
if !found {
return nil, types.ErrNoValidatorFound
}
// delegate the unbonding amount to validator back
_, err = k.Keeper.Delegate(ctx, delegatorAddress, msg.Amount.Amount, types.Unbonding, validator, false)
if err != nil {
return nil, err
}
_, err := ms.Keeper.CancelUnbondingDelegation(ctx,delegatorAddress,validatorAddress,amount,creation_height)
if err != nil {
return nil, err
}
return &types.MsgCancelUnbondingDelegationResponse{}, nil
}
```
#### `cli tx` Method
```bash=
simd tx staking cancel-unbond [validator-address] [amount] [creation_height] --from [user] --chain-id [chain-id]
Example:
simd tx staking cancel-unbond cosmosvaloper1mqtyv4qux68r26mql2hjhgrvz72snjwpulq22m 100000stake 10280 --from test1 --chain-id test-chain
```

* update staking specs
* use gosimple code in x/staking/client/testutil/suite.go
* small fixes
* add godoc to methods in msg_server and grpc_query
* changes to godoc and small fixes
* remove unnecessary lines
* remove mentions of serviceMsg and avoid having slash after Msg
* testing: refactore Validation and Delegation handling of x/staking
This Changeset introduces set of improvements for writing tests.
The idea is to create a testing subpackage which will provide functions
to make tests more dev-friendly and wrap higher level use-cases.
Here is a show-up of of creating a service for staking module
for tests.
This PR also changes the `x/staking/types.MsgCreateValidator.Pubkey` from string
to types.Any. This change motivated the other change to show the pattern I'm describing here.
* add validator checks
* type change fixes
* use deprecated
* adding test slashing
* new network comment update
* working on tests
* Fix TestMsgPkDecode test
* Add UnpackInterfaces to MsgCreateValidator
* Fix tests
* Convert bech32 pubkey to proto
* Fix test
* fix v039/migrate_test/TestMigrate
* fix tests
* testslashing: rename Service to Helper
* file rename
* update TestMsgDecode
