Detailed Description of the Problem
as requested on the mailing list I file this as an issue to keep track of it:
After noticing this some years ago, I ran into this again: The haproxy configuration examples and tutorials like the one at https://www.haproxy.com/documentation/haproxy-configuration-tutorials/proxying-essentials/custom-rules/stick-tables/ propose the use of "stick-table type ip ...". While the name "ip" suggests that this can be actually any IP address this is limiting the stick-table to IPv4 only. To use stick-tables that work for both IPv4 and IPv6, you have to use "stick-table type ipv6 ...". This is counter-intuitive from the naming and it's bad for all the documentation that proposes such configurations that don't work for IPv6.
Expected Behavior
I'd propose to introduce a "ipv4" for stick-tables and make "ip" an alias for "ipv6" as the latter one works for both IPv4 and IPv6. Second best option would at least be to fix the documentation and make the examples IPv6 proof.
Steps to Reproduce the Behavior
Willy's reply:
I was absolutely certain that it was already the case, I thought we had
changed this years ago. But checking the code it's indeed not the case,
that's a bit of a shock to me! I think we had discussed it and nothing
changed, for whatever reasons possibly ranging from "not the right moment"
to "will use more RAM".
However, this is a breaking change, we cannot afford to do that right now
in LTS but we could plan it for 3.3. We could also accept ipv4 right now
so as to ease the transition to new versions.
Do you have any idea what may have caused this?
