We keep getting DATA RACE conditions (or total crashes and outages that require manual restarts in the middle of the night)
and besides other issues with concurrency suspected in Vars Middleware, Replacer, Matcher
also the (newly in us) cache-handler/souin "middleware" is one of the suspects.

It's possible that this happened in a "HTTP-Connection-Destructor" or similar related to closing a lot of open tabs, but I could be totally wrong.

Posting this here for future reference:

Not able to spend more time on collecting all "standard" details, as it's obvious that none of them help reproduce such rare issues, until we have a way to reproduce both data+timing in a consistent way.

The fork/build used is this one, which already. uses rwmutex + for the Vars Middleware so at least some potential problems can be excluded.

We've seen more Cache/Souin-related DATA RACE problems, as mentioned, but only on local builds.

Hey @christophcemper I see that you're using v1.6.47, there were some improvements since v1.7.0 can you try with this version.
I'm trying to find a way to reproduce your issue with v1.7.5 but that's tricky, what's I'm suspecting:
Two request comes to the RP
A (first), B (second)
A goes to the upstream
B waits for the A return
A is canceled
B got an empty response and crashed.

I'll write a unit test/integration test and see if it reproduces the data race.

From the logs: Reused response from concurrent .

Thanks for the quick response @darkweak !

Here's another DATA RACE based on Caddy v2.8.4 but not newer souin, for you and Matt hopefully helpful
based on this fork version

  • local build based on 2.8.4-rwmutexplus3
  • LRTcaddy-v2.8.4-v1.4.0-v0.12.0-race-20241115-v2.8.4-rwmutexplus3-local-00:04:09
