+[![CircleCI](https://circleci.com/gh/tendermint/abci.svg?style=svg)](https://circleci.com/gh/tendermint/abci) + +Blockchains are systems for multi-master state machine replication. +**ABCI** is an interface that defines the boundary between the replication engine (the blockchain), +and the state machine (the application). +Using a socket protocol, a consensus engine running in one process +can manage an application state running in another. + +Previously, the ABCI was referred to as TMSP. + +The community has provided a number of addtional implementations, see the [Tendermint Ecosystem](https://tendermint.com/ecosystem) + +## Specification + +A detailed description of the ABCI methods and message types is contained in: + +- [A prose specification](specification.md) +- [A protobuf file](https://github.com/tendermint/abci/blob/master/types/types.proto) +- [A Go interface](https://github.com/tendermint/abci/blob/master/types/application.go). + +For more background information on ABCI, motivations, and tendermint, please visit [the documentation](http://tendermint.readthedocs.io/en/master/). +The two guides to focus on are the `Application Development Guide` and `Using ABCI-CLI`. + + +## Protocl Buffers + +To compile the protobuf file, run: + +``` +make protoc +``` + +See `protoc --help` and [the Protocol Buffers site](https://developers.google.com/protocol-buffers) +for details on compiling for other languages. Note we also include a [GRPC](http://www.grpc.io/docs) +service definition. + +## Install ABCI-CLI + +The `abci-cli` is a simple tool for debugging ABCI servers and running some +example apps. To install it: + +``` +go get github.com/tendermint/abci +cd $GOPATH/src/github.com/tendermint/abci +make get_vendor_deps +make install +``` + +## Implementation + +We provide three implementations of the ABCI in Go: + +- Golang in-process +- ABCI-socket +- GRPC + +Note the GRPC version is maintained primarily to simplify onboarding and prototyping and is not receiving the same +attention to security and performance as the others + +### In Process + +The simplest implementation just uses function calls within Go. +This means ABCI applications written in Golang can be compiled with TendermintCore and run as a single binary. + +See the [examples](#examples) below for more information. + +### Socket (TSP) + +ABCI is best implemented as a streaming protocol. +The socket implementation provides for asynchronous, ordered message passing over unix or tcp. +Messages are serialized using Protobuf3 and length-prefixed with a [signed Varint](https://developers.google.com/protocol-buffers/docs/encoding?csw=1#signed-integers) + +For example, if the Protobuf3 encoded ABCI message is `0xDEADBEEF` (4 bytes), the length-prefixed message is `0x08DEADBEEF`, since `0x08` is the signed varint +encoding of `4`. If the Protobuf3 encoded ABCI message is 65535 bytes long, the length-prefixed message would be like `0xFEFF07...`. + +Note the benefit of using this `varint` encoding over the old version (where integers were encoded as `` is that +it is the standard way to encode integers in Protobuf. It is also generally shorter. + +### GRPC + +GRPC is an rpc framework native to Protocol Buffers with support in many languages. +Implementing the ABCI using GRPC can allow for faster prototyping, but is expected to be much slower than +the ordered, asynchronous socket protocol. The implementation has also not received as much testing or review. + +Note the length-prefixing used in the socket implementation does not apply for GRPC. + +## Usage + +The `abci-cli` tool wraps an ABCI client and can be used for probing/testing an ABCI server. +For instance, `abci-cli test` will run a test sequence against a listening server running the Counter application (see below). +It can also be used to run some example applications. +See [the documentation](http://tendermint.readthedocs.io/en/master/) for more details. + +### Examples + +Check out the variety of example applications in the [example directory](example/). +It also contains the code refered to by the `counter` and `kvstore` apps; these apps come +built into the `abci-cli` binary. + +#### Counter + +The `abci-cli counter` application illustrates nonce checking in transactions. It's code looks like: + +```golang +func cmdCounter(cmd *cobra.Command, args []string) error { + + app := counter.NewCounterApplication(flagSerial) + + logger := log.NewTMLogger(log.NewSyncWriter(os.Stdout)) + + // Start the listener + srv, err := server.NewServer(flagAddrC, flagAbci, app) + if err != nil { + return err + } + srv.SetLogger(logger.With("module", "abci-server")) + if err := srv.Start(); err != nil { + return err + } + + // Wait forever + cmn.TrapSignal(func() { + // Cleanup + srv.Stop() + }) + return nil +} +``` + +and can be found in [this file](cmd/abci-cli/abci-cli.go). + +#### kvstore + +The `abci-cli kvstore` application, which illustrates a simple key-value Merkle tree + +```golang +func cmdKVStore(cmd *cobra.Command, args []string) error { + logger := log.NewTMLogger(log.NewSyncWriter(os.Stdout)) + + // Create the application - in memory or persisted to disk + var app types.Application + if flagPersist == "" { + app = kvstore.NewKVStoreApplication() + } else { + app = kvstore.NewPersistentKVStoreApplication(flagPersist) + app.(*kvstore.PersistentKVStoreApplication).SetLogger(logger.With("module", "kvstore")) + } + + // Start the listener + srv, err := server.NewServer(flagAddrD, flagAbci, app) + if err != nil { + return err + } + srv.SetLogger(logger.With("module", "abci-server")) + if err := srv.Start(); err != nil { + return err + } + + // Wait forever + cmn.TrapSignal(func() { + // Cleanup + srv.Stop() + }) + return nil +} +``` diff --git a/abci/client/client.go b/abci/client/client.go new file mode 100644 index 000000000..cdf2c60e7 --- /dev/null +++ b/abci/client/client.go @@ -0,0 +1,129 @@ +package abcicli + +import ( + "fmt" + "sync" + + "github.com/tendermint/tendermint/abci/types" + cmn "github.com/tendermint/tmlibs/common" +) + +const ( + dialRetryIntervalSeconds = 3 + echoRetryIntervalSeconds = 1 +) + +// Client defines an interface for an ABCI client. +// All `Async` methods return a `ReqRes` object. +// All `Sync` methods return the appropriate protobuf ResponseXxx struct and an error. +// Note these are client errors, eg.

It is left to prevent link breakages for the forseable future. It can safely be deleted in a few months. + +Message Types +~~~~~~~~~~~~~ + +ABCI requests/responses are defined as simple Protobuf messages in `this +schema +file `__. +TendermintCore sends the requests, and the ABCI application sends the +responses. Here, we provide an overview of the messages types and how they +are used by Tendermint. Then we describe each request-response pair as a +function with arguments and return values, and add some notes on usage. + +Some messages (``Echo, Info, InitChain, BeginBlock, EndBlock, Commit``), don't +return errors because an error would indicate a critical failure in the +application and there's nothing Tendermint can do. The problem should be +addressed and both Tendermint and the application restarted. All other +messages (``SetOption, Query, CheckTx, DeliverTx``) return an +application-specific response ``Code uint32``, where only ``0`` is reserved for +``OK``. + +Some messages (``SetOption, Query, CheckTx, DeliverTx``) return +non-deterministic data in the form of ``Info`` and ``Log``. The ``Log`` is +intended for the literal output from the application's logger, while the +``Info`` is any additional info that should be returned. + +The first time a new blockchain is started, Tendermint calls ``InitChain``. +From then on, the Block Execution Sequence that causes the committed state to +be updated is as follows: + +``BeginBlock, [DeliverTx], EndBlock, Commit`` + +where one ``DeliverTx`` is called for each transaction in the block. +Cryptographic commitments to the results of DeliverTx, EndBlock, and +Commit are included in the header of the next block. + +Tendermint opens three connections to the application to handle the different message +types: + +- ``Consensus Connection - InitChain, BeginBlock, DeliverTx, EndBlock, Commit`` + +- ``Mempool Connection - CheckTx`` + +- ``Info Connection - Info, SetOption, Query`` + +The ``Flush`` message is used on every connection, and the ``Echo`` message +is only used for debugging. + +Note that messages may be sent concurrently across all connections - +a typical application will thus maintain a distinct state for each +connection. They may be referred to as the ``DeliverTx state``, the +``CheckTx state``, and the ``Commit state`` respectively. + +See below for more details on the message types and how they are used. + +Echo +^^^^ + +- **Arguments**: + + - ``Message (string)``: A string to echo back + +- **Returns**: + + - ``Message (string)``: The input string + +- **Usage**: + + - Echo a string to test an abci client/server implementation + +Flush +^^^^^ + +- **Usage**: + + - Signals that messages queued on the client should be flushed to + the server.
