As per #2127, this refactors the RequestCheckTx ProtoBuf struct to allow for a flag indicating whether a query is a recheck or not (and allows for possible future, more nuanced states). In order to pass this extended information through to the ABCI app, the proxy.AppConnMempool (and, for consistency, the proxy.AppConnConsensus) interface seems to need to be refactored along with abcicli.Client. And, as per this comment, I've made the following modification to the protobuf definition for the RequestCheckTx structure: enum CheckTxType { New = 0; Recheck = 1; } message RequestCheckTx { bytes tx = 1; CheckTxType type = 2; } * Refactor ABCI CheckTx to notify of recheck As per #2127, this refactors the `RequestCheckTx` ProtoBuf struct to allow for: 1. a flag indicating whether a query is a recheck or not (and allows for possible future, more nuanced states) 2. an `additional_data` bytes array to provide information for those more nuanced states. In order to pass this extended information through to the ABCI app, the `proxy.AppConnMempool` (and, for consistency, the `proxy.AppConnConsensus`) interface seems to need to be refactored. Commits: * Fix linting issue * Add CHANGELOG_PENDING entry * Remove extraneous explicit initialization * Update ABCI spec doc to include new CheckTx params * Rename method param for consistency * Rename CheckTxType enum values and remove additional_data param
Application BlockChain Interface (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
Installation & Usage
To get up and running quickly, see the getting started guide along with the abci-cli documentation which will go through the examples found in the examples directory.
Specification
A detailed description of the ABCI methods and message types is contained in:
Protocol Buffers
To compile the protobuf file, run (from the root of the repo):
make protoc_abci
See protoc --help and the Protocol Buffers site
for details on compiling for other languages. Note we also include a GRPC
service definition.
