Subject: luci-app-statistics - allow rrd files to contain :
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=7bab4a3ef23397991c7f2296508cd52be20b4e49;p=oweals%2Fluci.git

luci-app-statistics - allow rrd files to contain :

Fixes situations where RRD file name contains ":" (eg. _ping/ipv6_) in `rrdtool` it's unescaped - thus not able to render image. Adding simple escaping of `:` to `\\:` fixes the situation.

Might be a solution for #958.
