Hi, HAProxy 3.0-dev11 was released on 2024/05/10. It added 43 new commits after version 3.0-dev10.
Another very calm release, thanks to two days off here in France, combined with the return of the sun today :-) Some 3.0 regressions were fixed, such as the broken logs over TCP after recent ring changes, and a QUIC crash when sending STOP_SENDING after the stream above was detached. The RST_STREAM reason code can finally be forwarded to the server for client aborts. This addresses the problem a few users were facing with gRPC where the abort reason was not respected. For now this is purposely limited to only a few reason codes that are relevant to gRPC so that we don't ruin the possibility to later extend that to H3 and maybe H1. We also managed to address the design issue around the buffer_wait code (the stuff that queues tasks waiting for a buffer on low memory). Now tasks are queued by criticality depending on what buffer is missing, so as to guarantee forward progress. It works pretty well for H1 and applets already so that convinced me that we should finish it instead of dropping all that. H2 and a few other places still need to be slightly revisited, and I'd like to also merge a simplification that I experimented with that allows the scheduler to deal itself with waiters instead of having every user think about calling offer_buffers() when leaving. For now that part was put to pause because doing it revealed another recent hard-to-trigger regression that we'll work on early next week. Finally, the build on Illumos was fixed, the log format options are now processed at boot time to improve runtime processing performance, and as usual, a few cleanups, doc and CI updates were included. Overall this is getting good and I think we're on the right track for a release around the end of the month.
