CHANGELOG

0.7.0 (unreleased)

Breaking: hyper-1.0 for both server and client modules.
Breaking: Remove override_host option in upstream options. Add a reverse option, i.e., disable_override_host. That is, rpxy always override the host header by the upstream hostname by default.
Breaking: Introduced native-tls-backend feature to use the native TLS engine to access backend applications.
Redesigned: Cache structure is totally redesigned with more memory-efficient way to read from cache file, and more secure way to strongly bind memory-objects with files with hash values.
Redesigned: HTTP body handling flow is also redesigned with more memory-and-time efficient techniques without putting the whole objects on memory by using futures::stream::Stream and futures::channel::mpsc
Refactor: lots of minor improvements

Feat: Add a build feature of native-roots to use the system's default root cert store.
Feat: Add binary release in addition to container release
Refactor: lots of minor improvements

Fix: fix a "watch" bug for docker. Due to a docker limitation, we need to mount a dir, e.g, /rpxy/config, instead of a file, rpxy.toml, to track changes of the configuration file. We thus updated a start up script in docker container for the case "WATCH=true".

Feat: Enabled h2c (HTTP/2 cleartext) requests to upstream app servers (in the previous versions, only HTTP/1.1 is allowed for cleartext requests)
Feat: Initial implementation of caching feature using file + on memory cache. (Caveats: No persistance of the cache. Once config is updated, the cache is totally eliminated.)
Refactor: lots of minor improvements

Fix: fix server in the response header (rpxy_lib -> rpxy)
Fix: fix bug for hot-reloading configuration file (Add termination notification receiver in proxy services)

Feat: s2n-quic with s2n-quic-h3 is supported as QUIC and HTTP/3 library in addition to quinn with h3-quinn, related to #57.
Feat: Publish dockerfile for rpxy with s2n-quic on both amd64 and arm64.
Feat: Start to publish docker images on ghcr.io
Refactor: logs of minor improvements

Feat: Continuous watching on a specified config file and hot-reloading the file when updated
Feat: Enabled to specify TCP listen backlog in the config file
Feat: Add a GitHub action to build arm64 docker image.
Bench: Add benchmark result on amd64 architecture.
Refactor: Split rpxy into rpxy-lib and rpxy-bin
Refactor: lots of minor improvements

HTTP/3 Deps: Update h3 with quinn-0.10 or higher. But changed their crates from crates.io to git submodule as a part of work around. I think this will be back to crates.io in a near-future update.
Load Balancing: Implement the session persistance function for load balancing using sticky cookie (initial implementation). Enabled in default-features.
Docker UID:GID: Update Dockerfiles to allow arbitrary UID and GID (non-root users) for rpxy. Now they can be set as you like by specifying through env vars.
Refactor: Various minor improvements

Update docker of nightly built from develop branch along with amd64-slim and amd64 images with latest and latest:slim tags built from main branch. nightly image is based on amd64.
Update h3 with quinn-0.10 or higher.
Implement path replacing option for each reverse proxy backend group.
