From 48ea1a7b5f1d4ca784e3d6da8d33e1461c24733c Mon Sep 17 00:00:00 2001 From: Mingwei Zhang Date: Fri, 27 Mar 2026 20:53:06 -0700 Subject: [PATCH 1/6] refactor: client-first architecture with flat module layout MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Reorganize the codebase around OneIo as the central type. Free-standing functions (get_reader, download, etc.) are now thin wrappers over a shared default OneIo client via default_oneio(). Module layout: - Remove src/oneio/ sub-directory; all modules moved to src/ - Split client.rs (OneIo impl) and builder.rs (OneIoBuilder + default_oneio) - Merge src/oneio/compressions/*.rs into single src/compression.rs - Extract ProgressReader into src/progress.rs - Extract async functions into src/async_reader.rs OneIoBuilder additions: - header(HeaderName, HeaderValue) and header_str(&str, &str) — infallible header API - user_agent(HeaderValue) — infallible, previously returned Result - configure_http(f) — escape hatch for any reqwest::blocking::ClientBuilder option - timeout(), connect_timeout(), proxy(), no_proxy(), redirect() - add_root_certificate_pem(), add_root_certificate_der() - ONEIO_CA_BUNDLE env var support OneIo additions: - get_reader_with_type(path, compression) — explicit compression override - from_client(Client) — construct from existing reqwest client - download_with_retry() uses exponential backoff between attempts Error type updates: - OneIoError is now #[non_exhaustive] - Add NetworkWithContext { url, source } for network errors with URL context - Add InvalidHeader and InvalidCertificate variants Bug fixes: - Compression detection strips URL query params and fragments before reading the file extension (e.g. file.gz?token=x now detects gz correctly) --- CHANGELOG.md | 30 ++ examples/progress_tracking.rs | 2 +- src/async_reader.rs | 134 ++++++ src/bin/oneio.rs | 2 +- src/builder.rs | 216 +++++++++ src/client.rs | 296 +++++++++++++ src/compression.rs | 154 +++++++ src/crypto.rs | 84 ++++ src/{oneio => }/digest.rs | 17 +- src/error.rs | 18 +- src/lib.rs | 381 ++++++---------- src/oneio/compressions/bzip2.rs | 36 -- src/oneio/compressions/gzip.rs | 38 -- src/oneio/compressions/lz4.rs | 40 -- src/oneio/compressions/mod.rs | 112 ----- src/oneio/compressions/xz.rs | 35 -- src/oneio/compressions/zstd.rs | 39 -- src/oneio/crypto.rs | 124 ------ src/oneio/mod.rs | 751 -------------------------------- src/oneio/remote.rs | 351 --------------- src/oneio/utils.rs | 121 ----- src/progress.rs | 39 ++ src/remote.rs | 109 +++++ src/{oneio => }/s3.rs | 354 +-------------- tests/CERTIFICATES.md | 68 +++ tests/basic_integration.rs | 233 ++++++++++ tests/test-cert.der | Bin 0 -> 911 bytes tests/test-cert.pem | 21 + tests/test-key.pem | 28 ++ tests/test_data.json | 6 + 30 files changed, 1579 insertions(+), 2260 deletions(-) create mode 100644 src/async_reader.rs create mode 100644 src/builder.rs create mode 100644 src/client.rs create mode 100644 src/compression.rs create mode 100644 src/crypto.rs rename src/{oneio => }/digest.rs (63%) delete mode 100644 src/oneio/compressions/bzip2.rs delete mode 100644 src/oneio/compressions/gzip.rs delete mode 100644 src/oneio/compressions/lz4.rs delete mode 100644 src/oneio/compressions/mod.rs delete mode 100644 src/oneio/compressions/xz.rs delete mode 100644 src/oneio/compressions/zstd.rs delete mode 100644 src/oneio/crypto.rs delete mode 100644 src/oneio/mod.rs delete mode 100644 src/oneio/remote.rs delete mode 100644 src/oneio/utils.rs create mode 100644 src/progress.rs create mode 100644 src/remote.rs rename src/{oneio => }/s3.rs (51%) create mode 100644 tests/CERTIFICATES.md create mode 100644 tests/test-cert.der create mode 100644 tests/test-cert.pem create mode 100644 tests/test-key.pem create mode 100644 tests/test_data.json diff --git a/CHANGELOG.md b/CHANGELOG.md index c52d370..6134b0e 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -4,16 +4,46 @@ All notable changes to this project will be documented in this file. ## [Unreleased] +### Breaking changes +- `OneIoError` is now `#[non_exhaustive]`;

now always use the progress path on a terminal - Align --download and s3 download progress behavior: both try the progress bar on a terminal regardless of whether file size is known - Progress bar no longer uses hidden/reveal dance; bar writes to stderr immediately with a spinner when total size is unknown - Fix parse_header to split on first ':' only, accepting both "Name: Value" and "Name:Value" formats - Document that --compression is ignored when --download is used - Extract build_oneio() and s3_credentials_or_exit() helpers - Shorten success messages ("uploaded to ...", "downloaded to ...") - Fix get_reader_with_progress callback signature in README (Fn(u64, u64)) - Update README CLI examples to match actual output --- CHANGELOG.md | 9 ++ Cargo.toml | 3 +- README.md | 388 +++++++++++++++++++++++++++++++++-------------- src/bin/oneio.rs | 300 ++++++++++++++++++++++++++---------- 4 files changed, 504 insertions(+), 196 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 6134b0e..b544626 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -41,6 +41,15 @@ All notable changes to this project will be documented in this file. - Added a benchmark helper script for comparing gzip backend feature flags and bz2 decompression - Added reusable `OneIo` and `OneIoBuilder` APIs for sharing headers and TLS certificate configuration across requests +### CLI +- Added `-H`/`--header` flag for custom HTTP headers (`"Name: Value"` or `"Name:Value"`), can be repeated +- Added `--compression` flag to override compression detection (gz, bz2, lz4, xz, zst);

Bug fix: LZ4 compressed writes were silently truncated because lz4::Encoder has no Drop impl and requires an explicit finish() call to write the end-of-stream frame marker. Fixed with a Lz4Writer wrapper in compression.rs that calls finish() on drop. The write tests caught this regression. New tests: - LZ4/XZ/Zstd: read, write round-trip, get_reader_with_type override - Progress: callback fires with correct bytes/total on HTTP and local files - Cache reader: creation, reuse, force-refresh, nested directory creation - JSON: struct deserialization, invalid input returns error - Content length: local file via metadata, HTTP with Content-Length header - Error variants: InvalidCertificate (PEM + DER), network error display - Env vars: ONEIO_CA_BUNDLE (valid + missing path), ONEIO_ACCEPT_INVALID_CERTS - SHA256 digest: known hash assertion, missing file returns error - get_writer_raw: creates plain uncompressed file, creates parent directories --- CHANGELOG.md | 3 + TEST_PLAN.md | 218 +++++++++++++++++++ src/compression.rs | 30 ++- tests/basic_integration.rs | 428 +++++++++++++++++++++++++++++++++++++ 4 files changed, 678 insertions(+), 1 deletion(-) create mode 100644 TEST_PLAN.md diff --git a/CHANGELOG.md b/CHANGELOG.md index b544626..e643a6c 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -50,6 +50,9 @@ All notable changes to this project will be documented in this file. - Terminal detection uses `std::io::IsTerminal` from the standard library; no extra dependency needed - Added `indicatif` to the `cli` feature for progress bars +### Bug fixes +- LZ4 compressed writes were silently truncated: `lz4::Encoder` has no `Drop` impl and requires an explicit `finish()` call to write the end-of-stream marker.
