X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=bbf668a18a20fa52a28a9958357c159d99747cfe;p=thirdparty%2Fhaproxy.git

BUG/MINOR: applet: Fix applet_getword() to not return one extra byte

applet_getword() function is returning one extra byte when a string is
returned because the "ret" variable is not reset before the loop on the
data. The patch also fixes applet_getline().

It is a 3.3-specific issue. No need to backport.
