[squid-users] get many logentries "ACL is used in context without an ALE state. Assuming mismatch" after upgrade from 3.5 to 4.0.21 when using external helper

[Dieter Bloms]

Hello,

I used external helper with squid 3.5.xx several years without any
problem.
Now I tried to upgrade to squid 4.0.21 and squid seems to work fine, but
I get many logentries like:

--snip--
2017/09/14 07:43:12 kid3| WARNING: blockhostsdomain ACL is used in context without an ALE state. Assuming mismatch.
2017/09/14 07:43:12 kid3| WARNING: blockhostsip ACL is used in context without an ALE state. Assuming mismatch.
2017/09/14 07:44:12 kid4| WARNING: blockhostsdomain ACL is used in context without an ALE state. Assuming mismatch.
2017/09/14 07:44:12 kid4| WARNING: blockhostsip ACL is used in context without an ALE state. Assuming mismatch.
--snip--

when I switched the acls to a file list, the warnings are gone.

my acls for external helpers look like:

external_acl_type blockhostiptype ttl=3600 negative_ttl=3600 grace=50 children-max=10 children-startup=2 %DST /usr/bin/dnsbl-ip.pl bl
acl blockhostsip external blockhostiptype
external_acl_type blockhostdomaintype ttl=3600 negative_ttl=3600 grace=50 children-max=10 children-startup=2 %DST /usr/bin/dnsbl.pl dbl
acl blockhostsdomain external blockhostdomaintype

when I replaced to above lines with this two, the warnings are gone:

acl blockhostsip dst "/etc/squid/blockhosts.ips"
acl blockhostsdomain dstdomain "/etc/squid/blockhosts.domains"

but I want to use the external helpers, because the lists were updated
many times a day and a reconfigure of squid has an impact of 2-3 seconds.

As I said before, squid works fine and checks the acls, but I get many
warnings in the cache.log and don't know the cause of it.
