node: refactor node.NewNode (#3456) The node.NewNode method is pretty complex at the moment, an in order to address issues like #3156, we need to simplify the interface for partial node instantiation. In some places, we don't need to build up a full node (like in the node.TestCreateProposalBlock test), but the complexity of such partial instantiation needs to be reduced. This PR aims to eventually make this easier/simpler. See also this gist https://gist.github.com/thanethomson/56e1640d057a26186e38ad678a1d114c for some background work done when starting to refactor here. ## Commits: * [WIP] Refactor node.NewNode to simplify The `node.NewNode` method is pretty complex at the moment, an in order to address issues like #3156, we need to simplify the interface for partial node instantiation.

rpc: add support for batched requests/responses (#3534) Continues from #3280 in building support for batched requests/responses in the JSON RPC (as per issue #3213). * Add JSON RPC batching for client and server As per #3213, this adds support for [JSON RPC batch requests and responses](https://www.jsonrpc.org/specification#batch). * Add additional checks to ensure client responses are the same as results * Fix case where a notification is sent and no response is expected * Add test to check that JSON RPC notifications in a batch are left out in responses * Update CHANGELOG_PENDING.md * Update PR number now that PR has been created * Make errors start with lowercase letter * Refactor batch functionality to be standalone This refactors the batching functionality to rather act in a standalone way. In light of supporting concurrent goroutines making use of the same client, it would make sense to have batching functionality where one could create a batch of requests per goroutine and send that batch without interfering with a batch from another goroutine. * Add examples for simple and batch HTTP client usage * Check errors from writer and remove nolinter directives * Make error strings start with lowercase letter * Refactor examples to make them testable * Use safer deferred shutdown for example Tendermint test node * Recompose rpcClient interface from pre-existing interface components * Rename WaitGroup for brevity * Replace empty ID string with request ID * Remove extraneous test case * Convert first letter of errors.Wrap() messages to lowercase * Remove extraneous function parameter * Make variable declaration terse * Reorder WaitGroup.Done call to help prevent race conditions in the face of failure * Swap mutex to value representation and remove initialization * Restore empty JSONRPC string ID in response to prevent nil * Make JSONRPCBufferedRequest private * Revert PR hard link in CHANGELOG_PENDING * Add client ID for JSONRPCClient This adds code to automatically generate a randomized client ID for the JSONRPCClient, and adds a check of the IDs in the responses (if one was set in the requests). * Extract response ID validation into separate function * Remove extraneous comments * Reorder fields to indicate clearly which are protected by the mutex * Refactor for loop to remove indexing * Restructure and combine loop * Flatten conditional block for better readability * Make multi-variable declaration slightly more readable * Change for loop style * Compress error check statements * Make function description more generic to show that we support different protocols * Preallocate memory for request and result objects

In this PR, each and every `PanicXXX` function call is replaced with a simple `panic` call. * add a changelog entry

mempool: remove only valid (Code==0) txs on Update (#3625) * mempool: remove only valid (Code==0) txs on Update so evil proposers can't drop valid txs in Commit stage. Also remove invalid (Code!=0) txs from the cache so they can be resubmitted. Fixes #3322 @rickyyangz: In the end of commit stage, we will update mempool to remove all the txs in current block. // Update mempool. err = blockExec.mempool.Update( block.Height, block.Txs, TxPreCheck(state), TxPostCheck(state), ) Assum an account has 3 transactions in the mempool, the sequences are 100, 101 and 102 separately, So an evil proposal can only package the 101 and 102 transactions into its proposal block, and leave 100 still in mempool, then the two txs will be removed from all validators' mempool when commit. So the account lost the two valid txs. @ebuchman: In the longer term we may want to do something like #2639 so we can validate txs before we commit the block. But even in this case we'd only want to run the equivalent of CheckTx, which means the DeliverTx could still fail even if the CheckTx passes depending on how the app handles the ABCI Code semantics. So more work will be required around the ABCI code. See also #2185 * add changelog entry and tests * improve changelog message * reformat code
