Key architectural decisions: + +1. **Multiple Runtime Support**: The library uses `maybe-async` to support tokio, async-std, and sync runtimes through feature flags +2. **Backend Abstraction**: HTTP requests are abstracted through backend modules: + - `request/tokio_backend.rs` - Tokio + reqwest + - `request/async_std_backend.rs` - async-std + surf + - `request/blocking.rs` - Sync implementation with attohttpc + +3. **Request Signing**: AWS Signature V4 implementation in `s3/src/signing.rs` +4. **Streaming Support**: Large file operations support streaming to avoid memory issues + +### Feature Flags + +The library uses extensive feature flags to control dependencies: + +- **default**: `tokio-native-tls` runtime with native TLS +- **sync**: Synchronous implementation without async runtime +- **blocking**: Generates `*_blocking` variants of all async methods +- **fail-on-err**: Return Result::Err for HTTP errors +- **tags**: Support for S3 object tagging operations + +### Testing Approach + +Tests are primarily integration tests marked with `#[ignore]` that require actual S3 credentials. They're located inline within source files using `#[cfg(test)]` modules. Run ignored tests with: + +```bash +cargo test -- --ignored +``` + +## Important Implementation Notes + +1. **Request Retries**: All requests are automatically retried once on failure. Additional retries can be configured with `bucket.set_retries()` + +2. **Path vs Subdomain Style**: The library supports both path-style and subdomain-style bucket URLs. Subdomain style is default. + +3. **Presigned URLs**: The library supports generating presigned URLs for GET, PUT, POST, and DELETE operations without requiring credentials at request time. + +4. **Error Handling**: With `fail-on-err` feature (default), HTTP errors return `Result::Err`. Without it, errors are embedded in the response. + +5. **Streaming**: Use `get_object_stream` and `put_object_stream` methods for large files to avoid loading entire content in memory. + +## Code Conventions + +- Use existing error types from `s3/src/error.rs` +- Follow the async/sync abstraction pattern using `maybe_async` macros +- Integration tests should be marked with `#[ignore]` if they require credentials +- All public APIs should have documentation examples +- Maintain compatibility with multiple S3-compatible services (not just AWS) \ No newline at end of file diff --git a/Makefile b/Makefile index dbe5a02edf..2a78809534 100644 --- a/Makefile +++ b/Makefile @@ -1,24 +1,33 @@ all: ci-all -ci: s3-ci region-ci creds-ci +# Main CI targets - fmt and clippy first, then tests +ci: fmt clippy test -ci-all: s3-all region-ci creds-ci +ci-all: fmt clippy test-all +# Formatting targets fmt: s3-fmt region-fmt creds-fmt +# Clippy targets for all features clippy: s3-clippy region-clippy creds-clippy -s3-all: - cd s3; make test-all +# Test targets (run after fmt and clippy) +test: s3-test region-test creds-test + +test-all: s3-test-all region-test creds-test -s3-ci: - cd s3; make ci +# Test targets for individual crates +s3-test: + cd s3; make test-not-ignored + +s3-test-all: + cd s3; make test-all -region-ci: - cd aws-region; make ci +region-test: + cd aws-region; cargo test -creds-ci: - cd aws-creds; make ci +creds-test: + cd aws-creds; cargo test s3-fmt: cd s3; cargo fmt --all diff --git a/README.md b/README.md index 9033f36fea..dea114199c 100644 --- a/README.md +++ b/README.md @@ -71,6 +71,18 @@ All runtimes support either `native-tls` or `rustls-tls`, there are features for `Bucket` struct provides constructors for `path-style` paths, `subdomain` style is the default. `Bucket` exposes methods for configuring and accessing `path-style` configuration. `blocking` feature will generate a `*_blocking` variant of all the methods listed below. +#### LocalStack Compatibility + +When using LocalStack, you may need to skip sending the location constraint in bucket creation requests.
