We refactor our continuous integration workflow with the following goals in mind: - Run as few jobs as possible - Have the jobs finish as fast as possible - Have the jobs redo as little work as possible There are only so many jobs that GitHub Actions will run in parallel. Thus, it makes sense to not create massive matrices but instead group things together meaningfully. The new `test` job will: - Run once for each crate - Ensure that the crate compiles on its specified MSRV - Ensure that the tests pass - Ensure that there are no semver violations This is an improvement to before because we are running all of these in parallel which speeds up execution and highlights more errors at once. Previously, tests run later in the pipeline would not get run at all until you make sure the "first" one passes. We also previously did not verify the MSRV of each crate, making the setting in the `Cargo.toml` rather pointless. The new `cross` job supersedes the existing `wasm` job. This is an improvement because we now also compile the crate for windows and MacOS. Something that wasn't checked before. We assume that checking MSRV and the tests under Linux is good enough. Hence, this job only checks for compile-errors. The new `feature_matrix` ensures we compile correctly with certain feature combinations. `libp2p` exposes a fair few feature-flags. Some of the combinations are worth checking independently. For the moment, this concerns only the executor related transports together with the executor flags but this list can easily be extended. The new `clippy` job runs for `stable` and `beta` rust. Clippy gets continuously extended with new lints. Up until now, we would only learn about those as soon as a new version of Rust is released and CI would run the new lints. This leads to unrelated failures in CI. Running clippy on with `beta` Rust gives us a heads-up of 6 weeks before these lints land on stable. Fixes #2951.

Repository Structure
The main components of this repository are structured as follows:
-
core/
: The implementation oflibp2p-core
with itsTransport
andStreamMuxer
API on which almost all other crates depend. -
transports/
: Implementations of transport protocols (e.g. TCP) and protocol upgrades (e.g. for authenticated encryption, compression, ...) based on thelibp2p-core
Transport
API . -
muxers/
: Implementations of theStreamMuxer
interface oflibp2p-core
, e.g. (sub)stream multiplexing protocols on top of (typically TCP) connections. Multiplexing protocols are (mandatory)Transport
upgrades. -
swarm/
: The implementation oflibp2p-swarm
building onlibp2p-core
with the central interfacesNetworkBehaviour
andConnectionHandler
used to implement application protocols (seeprotocols/
). -
protocols/
: Implementations of application protocols based on thelibp2p-swarm
APIs. -
misc/
: Utility libraries. -
examples/
: Worked examples of built-in application protocols (seeprotocols/
) with commonTransport
configurations.
Community Guidelines
The libp2p project operates under the IPFS Code of Conduct.
tl;dr
- Be respectful.
- We're here to help: abuse@ipfs.io
- Abusive behavior is never tolerated.
- Violations of this code may result in swift and permanent expulsion from the IPFS [and libp2p] community.
- "Too long, didn't read" is not a valid excuse for not knowing what is in this document.
