Hi,
HAProxy 2.1.11 was released on 2021/01/08. It added 65 new commits
after version 2.1.10.
I'd like to remind everyone that 2.1 is living its last months as its end
of life was announced as Q1 2021 as anyone can see by typing "haproxy -v".
As long as it doesn't hurt to emit a few more releases, I don't care much
about keeping it alive a little bit if some still need it, but barring any
new serious bug, you should reasonably consider that it's likely the last
one you're going to deploy before upgrading to 2.2 or 2.3. As usual, if
for any reason you think you need it to be maintained a bit longer (e.g.
facing a regression in more recent ones), please let us know very quickly.
Here come the bugs that were fixed since 2.2.6:
- Gilchrist Dadaglo fixed a number of issues in the SPOA Python example,
particularly on the error handling path. I seem to understand that most
of them are related to risks of memory leaks. If you wrote some code
using them as a form of documentation, please have a look at the recent
changes there to see if you need to fix your code as well.
- Olivier fixed a problem affecting users of ARM-based Macs, whose
assembler takes the semi-colon as a comment instead of an instruction
delimiter, causing the CAS to fail and loop forever.
- Olivier and I addressed some memory ordering issues in the scheduler and
self-locked lists that triggered on AWS' new ARM Graviton2 platform. We
can thank Ashley Penney for all the useful tests and traces he provided!
- Christopher fixed a delay issue affecting tunnels, where MSG_MORE was
accidently left set, possibly delaying sending incomplete packets by up
to 200ms.
- Christopher also addressed a race condition affecting leastconn if a
server's weight is changed to zero at the same moment the server is
repositionned in the tree. In fact it's only an issue for 1.8 but the
code was not correct in more recent versions either, but they're just
more robust :-)
- Christopher fixed a possible dangling pointer in SPOE that could cause
random memory overwrites. Special thanks to Maciej Zdeb for tirelessly
deploying test patches and checking traces to narrow it down!
- Maciej fixed the sample fetches to retrieve messages cookies when
called without cookie name. This case was never properly handled,
contrary to what the doc says.
- Tim fixed a missing call to the H2 mux's wakeup function in some
cases. The bug could in theory cause some delays on long
responses having no otherwise traffic, but could not be observed.
- Thierry addressed a handful of low-importance Lua issues that were
found during a code review.
- Fred fixed a few bugs in the peers protocol parser and the dictionaries
that were occasionally causing peers to get desynchronized.
- the "concat" converter could corrupt its output if a non-string variable
was used in the middle (e.g. an integer).
That's roughly all for bugs. Two minor features were backported, one is
William Dauchy's new "build_info" field in the prometheus exporter, which
reports the exact haproxy version for those who need to adjust their
behavior depending on the version, and the second is the new "url_enc"
converter which eases encoding of anything to be placed used in a query
string (e.g. for a redirect that will be decoded using url_dec).
And there were the usual amount of build fixes and doc updates.
