Reference implementation of the Filecoin protocol, written in Go
7fddbb528d
This is aproposal for an additional flag --manual-stateless-deal and a corresponding API endpoint ClientStatelessDeal. This allows firing off an offline-style deal against a miner without keeping further track of it locally. Not keeping any local state introduces the limitation of requiring free storage deals, as there is nothing to tie the payment channel setup to. Rationale/need for this type of flow is the case of incredibly large sets of data nd deals, where the client and providers have prearranged payment ahead of time, and the client has a separate-from-lotus database of deal inventory. This way the client can use their lotus node merely as a network gateway, without running into any limitations currently present in both lotus as a whole and go-fil-markets in particular. Specific context for this work is filecoin-discover, where the requirement is to onboard ~ 12,000,000 individual deals against a pool of miners with whom the client has prearranged a relationship. |

Contribute
Lotus is a universally open project and welcomes contributions of all kinds: code, docs, and more. However, before making a contribution, we ask you to heed these recommendations:
- If the proposal entails a protocol change, please first submit a Filecoin Improvement Proposal.
- If the change is complex and requires prior discussion, open an issue or a discussion to request feedback before you start working on a pull request. This is to avoid disappointment and sunk costs, in case the change is not actually needed or accepted.
- Please refrain from submitting PRs to adapt existing code to subjective preferences. The changeset should contain functional or technical improvements/enhancements, bug fixes, new features, or some other clear material contribution. Simple stylistic changes are likely to be rejected in order to reduce code churn.
When implementing a change:
- Adhere to the standard Go formatting guidelines, e.g. Effective Go. Run
go fmt. - Stick to the idioms and patterns used in the codebase. Familiar-looking code has a higher chance of being accepted than eerie code. Pay attention to commonly used variable and parameter names, avoidance of naked returns, error handling patterns, etc.
- Comments: follow the advice on the Commentary section of Effective Go.
- Minimize code churn. Modify only what is strictly necessary. Well-encapsulated changesets will get a quicker response from maintainers.
- Lint your code with
golangci-lint(CI will reject your PR if unlinted). - Add tests.
- Title the PR in a meaningful way and describe the rationale and the thought process in the PR description.
- Write clean, thoughtful, and detailed commit messages. This is even more important than the PR description, because commit messages are stored inside the Git history. One good rule is: if you are happy posting the commit message as the PR description, then it's a good commit message.
