Subject: [OPTIM] halog: remove support for tab delimiters in input data
X-Git-Tag: v1.5-dev8~191
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=14389e703663adf7348ab938ed676292a35b8bf8;p=thirdparty%2Fhaproxy.git

[OPTIM] halog: remove support for tab delimiters in input data

Haproxy does not use tabs when sending logs, and checking for them
wastes no less than 4% of CPU cycles. Better get rid of these tests.
