Subject: MINOR: lua-thread: Add verbosity in errors
X-Git-Tag: v2.4-dev3~105
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=46278ff8286cde41e0f267c1d385661d6d20dff5;p=thirdparty%2Fhaproxy.git

MINOR: lua-thread: Add verbosity in errors

Because lua-load-per-thread could not load the same code for each thread,
this patch displays the state-id associated with the error.
