# Contributing
|
|
|
|
First, thank you for contributing to Meilisearch! The goal of this document is to provide everything you need to start contributing to Meilisearch.
|
|
|
|
Remember that there are many ways to contribute other than writing code: writing [tutorials or blog posts](https://github.com/meilisearch/awesome-meilisearch), improving [the documentation](https://github.com/meilisearch/documentation), submitting [bug reports](https://github.com/meilisearch/meilisearch/issues/new?assignees=&labels=&template=bug_report.md&title=) and [feature requests](https://github.com/meilisearch/product/discussions/categories/feedback-feature-proposal)...
|
|
|
|
Meilisearch can manage multiple indexes, handle the update store, and expose an HTTP API. Search and indexation are the domain of our core engine, [`milli`](https://github.com/meilisearch/meilisearch/tree/main/milli), while tokenization is handled by [our `charabia` library](https://github.com/meilisearch/charabia/).
|
|
|
|
If Meilisearch does not offer optimized support for your language, please consider contributing to `charabia` by following the [CONTRIBUTING.md file](https://github.com/meilisearch/charabia/blob/main/CONTRIBUTING.md) and integrating your intended normalizer/segmenter.

## How to Contribute
|
|
|
|
1. Ensure your change has an issue! Find an
|
|
[existing issue](https://github.com/meilisearch/meilisearch/issues/) or [open a new issue](https://github.com/meilisearch/meilisearch/issues/new).
|
|
* This is where you can get a feel if the change will be accepted or not.
|
|
2. Once approved, [fork the Meilisearch repository](https://help.github.com/en/github/getting-started-with-github/fork-a-repo) in your own GitHub account.
|
|
3. [Create a new Git branch](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-and-deleting-branches-within-your-repository)
|
|
4. Review the [Development Workflow](#development-workflow) section that describes the steps to maintain the repository.
|
|
5. Make your changes on your branch.
|
|
6. [Submit the branch as a Pull Request](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request-from-a-fork) pointing to the `main` branch of the Meilisearch repository. A maintainer should comment and/or review your Pull Request within a few days. Although depending on the circumstances, it may take longer.
|
|
|
|
## Development Workflow
|
|
|
|
### Setup and run Meilisearch
|
|
|
|
```bash
|
|
cargo run --release
|
|
```
|
|
|
|
We recommend using the `--release` flag to test the full performance of Meilisearch.
|
|
|
|
### Test
|
|
|
|
```bash
|
|
cargo test
|
|
```
|
|
|
|
This command will be triggered to each PR as a requirement for merging it.
|
|
|
|
#### Snapshot-based tests
|
|
|
|
We are using [insta](https://insta.rs) to perform snapshot-based testing.
|
|
We recommend using the insta tooling (such as `cargo-insta`) to update the snapshots if they change following a PR.
|
|
|
|
New tests should use insta where possible rather than manual `assert` statements.
|
|
|
|
Furthermore, we provide some macros on top of insta, notably a way to use snapshot hashes instead of inline snapshots, saving a lot of space in the repository.
|
|
|
|
To effectively debug snapshot-based hashes, we recommend you export the `MEILI_TEST_FULL_SNAPS` environment variable so that snapshot are fully created locally:
|
|
|
|
```
|
|
export MEILI_TEST_FULL_SNAPS=true # add this to your .bashrc, .zshrc, ...
|
|
```
|
|
|
|
#### Test troubleshooting
|
|
|
|
If you get a "Too many open files" error you might want to increase the open file limit using this command:
|
|
|
|
```bash
|
|
ulimit -Sn 3000
|
|
```
|
|
|
|
#### Build tools
|
|
|
|
Meilisearch follows the [cargo xtask](https://github.com/matklad/cargo-xtask) workflow to provide some build tools.
|
|
|
|
Run `cargo xtask --help` from the root of the repository to find out what is available.
|
|
|
|
### Logging
|
|
|
|
Meilisearch uses [`tracing`](https://lib.rs/crates/tracing) for logging purposes. Tracing logs are structured and can be displayed as JSON to the end user, so prefer passing arguments as fields rather than interpolating them in the message.
|
|
|
|
Refer to the [documentation](https://docs.rs/tracing/0.1.40/tracing/index.html#using-the-macros) for the syntax of the spans and events.
|
|
|
|
Logging spans are used for 3 distinct purposes:
|
|
|
|
1. Regular logging
|
|
2. Profiling
|
|
3. Benchmarking
|
|
|
|
As a result, the spans should follow some rules:
|
|
|
|
- They should not be put on functions that are called too often. That is because opening and closing a span causes some overhead. For regular logging, avoid putting spans on functions that are taking less than a few hundred nanoseconds. For profiling or benchmarking, avoid putting spans on functions that are taking less than a few microseconds.
|
|
- For profiling and benchmarking, use the `TRACE` level.
|
|
- For profiling and benchmarking, use the following `target` prefixes:
|
|
- `indexing::` for spans meant when profiling the indexing operations.
|
|
- `search::` for spans meant when profiling the search operations.
|
|
|
|
### Benchmarking
|
|
|
|
See [BENCHMARKS.md](./BENCHMARKS.md)
|
|
|
|
## Git Guidelines
|
|
|
|
### Git Branches
|
|
|
|
All changes must be made in a branch and submitted as PR.
|
|
|
|
We do not enforce any branch naming style, but please use something descriptive of your changes.
|
|
|
|
### Git Commits
|
|
|
|
As minimal requirements, your commit message should:
|
|
- be capitalized
|
|
- not finish by a dot or any other punctuation character (!,?)
|
|
- start with a verb so that we can read your commit message this way: "This commit will ...", where "..." is the commit message.
|
|
e.g.: "Fix the home page button" or "Add more tests for create_index method"
|
|
|
|
We don't follow any other convention, but if you want to use one, we recommend [the Chris Beams one](https://chris.beams.io/posts/git-commit/).
|
|
|
|
### GitHub Pull Requests
|
|
|
|
Some notes on GitHub PRs:
|
|
|
|
- All PRs must be reviewed and approved by at least one maintainer.
|
|
- The PR title should be accurate and descriptive of the changes.
|
|
- [Convert your PR as a draft](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/changing-the-stage-of-a-pull-request) if your changes are a work in progress: no one will review it until you pass your PR as ready for review.<br>
|
|
The draft PRs are recommended when you want to show that you are working on something and make your work visible.
|
|
- The branch related to the PR must be **up-to-date with `main`** before merging. Fortunately, this project uses [Bors](https://github.com/bors-ng/bors-ng) to automatically enforce this requirement without the PR author having to rebase manually.
|
|
|
|
## Release Process (for internal team only)
|
|
|
|
Meilisearch tools follow the [Semantic Versioning Convention](https://semver.org/).
|
|
|
|
### Automation to rebase and Merge the PRs
|
|
|
|
This project integrates a bot that helps us manage pull requests merging.<br>
|
|
_[Read more about this](https://github.com/meilisearch/integration-guides/blob/main/resources/bors.md)._
|
|
|
|
### How to Publish a new Release
|
|
|
|
The full Meilisearch release process is described in [this guide](https://github.com/meilisearch/engine-team/blob/main/resources/meilisearch-release.md). Please follow it carefully before doing any release.
|
|
|
|
### How to publish a prototype
|
|
|
|
Depending on the developed feature, you might need to provide a prototyped version of Meilisearch to make it easier to test by the users.
|
|
|
|
This happens in two steps:
|
|
- [Release the prototype](https://github.com/meilisearch/engine-team/blob/main/resources/prototypes.md#how-to-publish-a-prototype)
|
|
- [Communicate about it](https://github.com/meilisearch/engine-team/blob/main/resources/prototypes.md#communication)
|
|
|
|
### Release assets
|
|
|
|
For each release, the following assets are created:
|
|
- Binaries for different platforms (Linux, MacOS, Windows and ARM architectures) are attached to the GitHub release
|
|
- Binaries are pushed to HomeBrew and APT (not published for RC)
|
|
- Docker tags are created/updated:
|
|
- `vX.Y.Z`
|
|
- `vX.Y` (not published for RC)
|
|
- `latest` (not published for RC)
|
