zebrad: document Inbound, ChainSync responsibilities
2020-09-18 16:13:57 -07:00
//! Holds components of a Zebra node.
//!
//! Some, but not all, of these components are structured as Abscissa components,
//! while the others are just ordinary structures. This is because Abscissa's
//! component and dependency injection models are designed to work together, but
//! don't fit the async context well.
Re-order Zebra startup, so slow services are launched last (#3091) * Start network before verifiers This makes the Groth16 download task start as late as possible. * Explain why the Groth16 download must happen first * Speed up Zebra shutdown: skip waiting for the tokio runtime

Stop downloading unnecessary blocks in Zebra acceptance tests (#3072) * Implement graceful shutdown for the peer set * Use the minimum lookahead limit in acceptance tests * Enable a doctest that compiles with newly public modules

Create initial transaction crawler for the mempool (#2646) * Create initial `mempool::Crawler` type The mempool crawler is responsible for periodically asking peers for transactions to insert into the local mempool. This initial implementation will periodically ask for transactions, but won't do anything with them yet. Also, the crawler is currently configured to be always enabled, but this should be fixed to avoid crawling while Zebra is still syncing the chain. * Add a timeout to peer responses Prevent the crawler from getting stuck if there's communication with a peer that takes too long to respond. * Run the mempool crawler in Zebra Spawn a task for the crawler when Zebra starts. * Test if the crawler is sending requests Create a mock for the `PeerSet` service to intercept requests and verify that the transaction requests are sent periodically. * Use `full` Tokio features when testing Make it simpler to select the features for test builds. Co-authored-by: teor <teor@riseup.net> * Link to the issue for crawler activation Make it easy to navigate from the `TODO` comment to the current project planning.

Gossip recently verified block hashes to peers (#2729) * Implement a task that gossips verified block hashes * Log an info message for block broadcasts * Simplify the gossip task Co-authored-by: Janito Vaqueiro Ferreira Filho <janito.vff@gmail.com> * Re-use the old tip change if there is no new tip change Also improve the comments. * Add an assertion message * Rename task join handles and futures in start method * Add a dedicated BlockGossipError type This type helps distinguish between syncer and state errors. * Test that committed blocks are gossiped to peers Also do a minor type cleanup on the existing test code, replacing `Option<Vec<_>>` with `Vec<_>`. * Formatting * Remove excess newlines Co-authored-by: Alfredo Garcia <oxarbitrage@gmail.com> * Clear the initial gossiped blocks during test setup Co-authored-by: Janito Vaqueiro Ferreira Filho <janito.vff@gmail.com> Co-authored-by: Alfredo Garcia <oxarbitrage@gmail.com>

Tracing endpoint (#3) * Add a TracingConfig and some components Co-authored-by: Deirdre Connolly <deirdre@zfnd.org> * Restructure, use dependency injection, initialize tracing * Start a placeholder loop in start command * Add hyper alpha.1, bump tokio to alpha.4 * Hello world endpoint using async/await from hyper 0.13 alpha Also cleaned up some linter messages. Co-authored-by: Henry de Valence <hdevalence@hdevalence.ca> * Update to tracing_subscriber 0.1 * fmt * add rust-toolchain * Remove hyper::Version import * wip: start filter_handler impl * Add .rustfmt.toml * rustfmt * Tidy up .rustfmt.toml * Add filter reloading handling. * bump toolchain * Remove generated hello world acceptance tests. These test the behaviour of the autogenerated binary and work as examples of how to test the behaviour of abscissa binaries. Since we don't print "Hello World" any more, they fail, but we don't yet have replacement behaviour to add tests for, so they're removed for now. * Clean up config file handling with Option::and_then.

zebrad: move seed command into inbound component Remove the seed command entirely, and make the behavior it provided (responding to `Request::Peers`) part of the ordinary functioning of the start command. The new `Inbound` service should be expanded to handle all request types.
