Bug 247488 – net-proxy/squid epoll problem (+ squid-3.1.0.2 ebuild on example)

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Denis Kaganovich 2008-11-18 19:51:13 UTC]

In latest environment epoll unstable or slow (kernel+glibc versions related? not too test). Suggested "epoll" to be moved into USE.

I am too complex changing environment - kernel+glibc, then not too sure. In 2.6.27 + glibc-2.8_p20080602 squid was dead sleep, in 2.6.28 + 2.7-r2 ("way to destruction") - only temporary light sleeps. Universal solution - "--disable-epoll". Squid - 2.7 & 3.0. Then I suggest to add "epoll" into USE flags and disable by default. There are squid-3.1.0.2 ebuild (without ZPH & kerberos) with USE example.

Reproducible: Always

Fixed in versions 2.7.5-r1 3.0.10-r1 by adding epoll and kqueue USE flags.

[Comment 15 Denis Kaganovich 2008-12-08 17:59:16 UTC]

Also fixed in latest kernel 2.6.28 (Dec 1 13:13:55 2008).
I use:
echo 8192 >/proc/sys/fs/epoll/max_user_watches

I am not sure in this (8192) value, just equal to max file handles. You may add this into squid startup script or calculate more correct value.
