Hello Matthias, hello *,
by coincidence, I just stumbled across a Squid 5.4 source tarball on source.ipfire.org:
pmueller@people01:~$ ls -lah /pub/sources/source-2.x/squid-5.* -rw-r--r-- 1 mfischer people 2.5M Aug 2 2021 /pub/sources/source-2.x/squid-5.1.tar.xz -rw-r--r-- 1 mlorenz people 2.5M Oct 6 07:44 /pub/sources/source-2.x/squid-5.2.tar.xz -rw-r--r-- 1 mfischer people 2.5M Dec 7 18:42 /pub/sources/source-2.x/squid-5.3.tar.xz -rw-r--r-- 1 mfischer people 2.5M Feb 7 17:10 /pub/sources/source-2.x/squid-5.4.tar.xz
I therefore presume you are working on this one. :-)
While Squid 5.2, as it is now present in the upcoming Core Update 164, works fine, I observed at least one memory leak in it that eventually caused swapping on a productive infrastructure (under high load). Squid 5.4 should have that fixed.
Because of this, I'd like to have Squid 5.4 in Core Update 164, so our users won't have to suffer from this bug. It is good to see you are taking care of it. Please do not feel pressured in any way, I just thought I mention this to you. :-)
Thanks in advance for your efforts, and best regards, Peter Müller
