Sozu Versions Save

This is the first release of Sōzu which is a huge steps since the beginning of the project. We would like to thanks every people involved in the development of Sōzu. The next steps is to implements h2(c) on top of kawa with a rework of session to be able to use http 1.x clients with h2 backends and h2 clients with h2 backends, h2 clients with http 1.x backends.

🌟 Features

• This release is the first one that use protobuf-everywhere. It means that we are moving out from the old exchange model for sockets (which are data exchanges between main process and workers processes and also main process and control plane process) that use Rust structures that we serialize into json to structures described in protobuf that generate Rust source code and then communicate with binary format. Besides, this work also have some nice side-effects on fork when creating new workers (due to a self-healing or at start) which allow to reduce the time to configure a worker by around 50%. It also introduces a new way to emit access logs in a binary way, see [ dfacdb7 ], [ a6ffebe ], [ fb11245 ], [ 6daf43c ], [ 8e81a02 ], [ 24a941b ], [ 6d160b4 ], [ e382a1c ], [ 4f2d760 ], [ 6d43eb1 ] and [ 5852c6b ].
• We have reworked emitted logs and access logs format, if you are tools that parse them, you have to take a look at the new one. Besides, it will be easier to parse. Furthermore, we have added color on logs to improve readability, see [ 0885863 ], [ d3eeddc ], [ 3bb3997 ] and [ 5f55561 ].
• We have bump the minimum Rust supported version to v1.74.0, see [ 2c4363d ], [ 96f5329 ] and [ e6bcfe0 ].
• We have introduce a way to define custom http response for a wide range of status code, see 3f0bfa1, 4923153, b9df0c1, ee2430f, 3030944, 6023216, 55242ba, 55242ba, 8faa16c, a5058c2, fb6aad9 and a2236d1.
• We also fix a bug that could occur on some streaming https requests with tcp-keepalive when going through multiple Sōzu which does not flush correctly the ending chunk of data when calling rustls::write_vectored, see d83f399.
• We also change how works timeout on frontends as it is now closed by the backend, once we have received a first chunk of data, see 6114e17.

🚀 Performance

• Thanks to the work achieved on Rustls (v0.23.0) with the help of maintainers (a huge thanks to them ❤️), we have gain between 10% and 20% performance on https requests depending of the workload, see [ 7fa680d ].

⛑️ Fixed

• We have fixed a bug that occurs during http request when doing streaming and tcp keep-alive which prevent to send the close-delimiter on response, see [ 59c0615 ].
• We have fix a few bugs on certificate replacement and improve the resolution of certificates, see [ 6aa45b9 ].
• We have fix a bug that involved timeout on frontend sockets which did not take the given value, see [ d20e759 ].

✍️ Changed

• We have work on errors to have a better context when something happens, see [ ba8b51a ], [ 629551f ] and [ 1c90c04 ].

📚 Documentation

• We have added some documentation about logs and access logs, see [ d44b227 ] and [ 7241c0e ].
• We have reworked or improved examples, see [ 31bc55e ] and [ 95624e6 ].
• We have added some documentation of using Sōzu with firewalld (thanks @obreidenich), see [ 4cba552 ].
• We have setup a github continuous integration to provides and document a way to benchmark Sōzu (values on the ci are not reliable), see [ 8df9ba5 ].

Full Changelog: https://github.com/sozu-proxy/sozu/compare/0.15.19..1.0.0

🌟 Features

1.0.0-rc.1 - 2024-03-19

This changelog is the first release candidate before the version 1.0.0, its goal is to allow to migrate smoothly other crates as the sozu-client to be compatible with the protobuf-everywhere part and to be able to make tests on production at Clever-Cloud by doing some A/B testing.

🌟 Features

• This version is the first one that use protobuf-everywhere. It means that we are moving out from the old exchange model for sockets (which are data exchanges between main process and workers processes and also main process and control plane process) that use Rust structures that we serialize into json to structures described in protobuf that generate Rust source code and then communicate with binary format.

Full Changelog: https://github.com/sozu-proxy/sozu/compare/0.15.3...0.15.4

🌟 Features

• We have reworked the error management in the command library to remove anyhow in favor of thiserror, the idea behind is to give to the binary or library that use this crate a way to better understand the error and be able to differentiate, if something is going wrong or not and take actions, see e7b530d, d2e1dcc, d0389d8, 447bed5, aa55b97, 0a92877, a04fe34, e1e7ce2, bdde240, d109ccc, bda6913, cc341e3, 5c7a8ef, b919515 and f9353d2.
