SaunaFS 5.2.0 now stable!

[uristdwarf]

Hello everyone!

The released was delayed a bit (usually we try to release monthly). We had not seen any issues for 5.2.0, except one: We found a bug with .saunafs_path_by_inode, which causes it to lock up the application that not even SIGKILL can save.
We postponed the release a bit to investigate this. However, we found that this bug likely exists in earlier versions, so we decided to release the RC as is, and that issue will be fixed in the next release (it is already in dev).

So I'm glad to finally release 5.2.0 as stable. 🥳

The release comes with a new API, but otherwise is mostly just bug fixes. Here's some of the significant changes:

Significant Changes

• The performance feature from 5.1.0 and 5.1.1 that was reverted (multiple block writes per HDD job) has been re-introduced, with a proper fix to it.
• Fixed an issue where a stray SIGVALRM could cause shadow to crash.
• Fixed an issue where if a chunkserver/master stops or crashes, it would have lost chunks.
• Fixed CGI for python 3.13+
• Other, smaller fixes
• General refactoring

SaunaFS API

I'm also proud to introduce a REST API for monitoring SaunaFS. This is developed off this repository, and can be found here:

https://github.com/leil-io/saunafs-api

This API allows you to access the same things as the CGI, but through a simple REST API. This allows you to integrate with an existing monitoring system easily, or develop your own.

That's it for this release, as always, please report any bugs you find.
