Hi,
HAProxy 3.2-dev4 was released on 2025/01/24. It added 44 new commits
after version 3.2-dev3.
This version contains fixes for some visible bugs (most of which are
already either backported or planned for backporting). One issue
concerns a risk of crash in QUIC with too large crypto frames, another
one causes confusion on log servers having the same name in different
backends, and another one could leave some HTTP/1 connections blocked
till the timeout. The other bugs are just in the range of common ones.
Concerning the improvements, we have this:
- new sc_key() sample fetch to retrieve the key currently tracked
by a strick-counter. It can be useful for logging, for lookups
in other tables or anything like this. It has been missing for
a long time and can simplify some configurations (e.g. by no
longer having to set a variable to hold that value).
- new table_{inc,dec}_gpc* converters to act on gpc counters after
looking up the input sample. That's convenient to set match
thresholds.
- the parsing of the -dt keyword used to enable traces from the
command line was revamped to be more flexible and to provide a
help message explaining how to use it. Also -dt now has precedence
over the traces section.
- the QUIC pacing now works pretty well without wasting CPU cycles,
we managed to get back to millisecond resolution with excellent
results, even when the process is severely loaded. We intend to
enable it by default starting from dev5 since it will enable
easier testing and significantly improve performance (on a client
running on a small CPU core, the performance jumped by around x20
just thanks to significantly reducing losses).
- some updates to make the output of "show dev" more easily parsable
and friendlier.
- doc updates to mention the "any" type input on some converters,
the support for implicit tables, and a bit of consistency between
keywords regarding optional arguments syntax.
There are still pending series under review and about to be merged. One
of them concerns more detailed error statuses so that we finally know
in detail (and in the right order) the events that led to a connection
being terminated. Another one concerns the queues in high thread counts
environments, where we know it's still possible to see watchdogs on AMD
EPYC CPUs due to inter-CCX cache latency. If all goes well, this should
land in the branch next week or so, stay tuned.
In the mean time, please play with dev4. And if you're using QUIC and
want to test it with pacing, just add "expose-experimental-directives"
to your global section, and append "quic-cc-algo bbr" or "quic-cc-algo
cuboc(,1)" to your bind lines.
