Subject: [Fix] Use math.floor for Lua 5.4 integer division compatibility
X-Git-Tag: 3.14.2~14
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b4ed7bffe681162fcef340f3c90e3ba006f1992c;p=thirdparty%2Frspamd.git

[Fix] Use math.floor for Lua 5.4 integer division compatibility

In Lua 5.4, the / operator always returns a float (2/2 = 1.0), while
LuaJIT returns an integer (2/2 = 1). This caused test dependency
registration to fail as tostring(i/2) produced "1.0" instead of "1".
