Hi,
HAProxy 2.2.15 was released on 2021/07/16. It added 90 new commits
after version 2.2.14.
This release is very similar to the 2.3.11/2.3.12. To sum up, most
noticeable bugs fixed in this release are:
* A possible deadlock if "set maxconn server" command was used when there
was a pending connection ready to be dequeued.
* A possible infinite loop in process_stream() when a connection error was
reported while the stream was waiting for a retry.
* A possible race between free() and pool_alloc() in the pools lockless
variant.
* A bug in the HTX defragmentation leading to crash. The bug might be
encountered in the HTTP compression filter or in HTTP header
replacement.
* An old bug preventing the dequeuing for servers with a very low maxconn
because the load balancing was not skipped when a new connection was
picked from the proxy's or server's queue.
* A bug in the sock part leading to high CPU usage because some early
connection failures might be missed.
* A thread-safety issue with the SHCTX code when compiled with
USE_PRIVATE_CACHE mode. It was not using any locks.
* Most of resolvers performance issues and several other bugs in this area.
* An issue with the abortonclose option. It was not working since a while.
* A bug in the HTTP compression leading to truncated or corrupted
responses.
* A bug with synchronous connect in tcpcheck when several connections come
one after the other.
* "url_ip"/"url_port" sample fetches not properly handling url parsing
errors.
In addition, the http-ignore-probes is now respected for H2
connections. When this option is set, no errors are reported anymore when
connections are aborted during preface. And the FCGI multiplexer was
slightly improved to send a relative path instead of a normalized URI to an
application and to expose SERVER_SOFTWARE parameter by default. Finally, as
a consequence of the bug fixed in the pools, the code was simplified. The
lockless implementation is used everywhere, resulting in the removal of the
very old locked implementation that was kept for non-capable
architectures. As a result, threads will now be faster on less common
architectures (e.g. i686, MIPS, PPC64, ...). The rest is less visible but
contains, as usual, cleanups, small fixes here and there, improvements...
It is strongly advised to update to this version. Thanks everyone for your
help and your contributions!
