[squid-users] [squid][v5.6] : problem with "slow" or "fast" acl

[PERROT Eric DNUM SDCAST BST SSAIM]

Hello,

We use directives "reply_body_max_size", "request_body_max_size" and 
"delay_access" to limit upload, download and passband in our infra.

This configuration existes since a while, but we have noticed that with 
squid v4.16, our delay pool didn't react as we wanted anymore. We were 
excpeting improvment upgrading squid to v5.6. But it got worth :
- restriction still didn't work
- and squid had a segmentation fault each time some acl where used

Thanks to Alex Rousskov (bug 5231), after some investigation, it appears 
that we used "slow" acl (proxy_auth an time acl) where only "fast" acl 
where authorized...). The bug is still open as squid has not flagged the 
problem in cache logs,

My email, is to show you our configuration and the behaviour we espect, 
and the behaviour we finally have.
1 - squd v4.12 : we expect to limit downlod/upload and passband during 
working time for all login except those starting with cg_*

=> with this configuration, the delay pool seemed not to work anymore, 
so we upgraded squid to v5.6. Which caused the squid segmentation fault...

2 - squid v5.6 : to solve the segmentation fault, we had to take off 
my_ldap_auth/cgen (proxy_auth acl) and bureau (time acl). The limitation 
work again, but we are no more able to limit restriction during working 
time, or for spécific login...

Can you tell me if what we want to do is still possible? Limiting 
upload/download/passband for all logged user except those starting by 
cg_*..?.

Thank you for the time reading, and thank you for your answers.

Regards,

Eric Perrot
