1.0.0-rc.1

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. 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 ].

⛑️ 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 ].

🚀 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 ].

✍️ 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 ].
