[sr-dev] git:master: modules/app_lua: Fix to lua_sr_pv_is_null()

Module: sip-router Branch: master Commit: 4e4069330fd44e454c7db19b5d944dbe4ca46a39 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=4e40693… Author: pd <peter.dunkley(a)crocodile-rcs.com> Committer: pd <peter.dunkley(a)crocodile-rcs.com> Date: Fri Oct 14 13:55:24 2011 +0100 modules/app_lua: Fix to lua_sr_pv_is_null() - Previously this function returned an error when it could not retrieve the pv (for example if it did not exist). As Lua is not a language in which you have to declare variables not existing is equivalent to NULL. This function now treats a pv that does not exist as NULL. --- modules/app_lua/app_lua_sr.c | 5 +++-- 1 files changed, 3 insertions(+), 2 deletions(-) diff --git a/modules/app_lua/app_lua_sr.c b/modules/app_lua/app_lua_sr.c index 1271ba2..3a2bf72 100644 --- a/modules/app_lua/app_lua_sr.c +++ b/modules/app_lua/app_lua_sr.c @@ -1081,8 +1081,9 @@ static int lua_sr_pv_is_null (lua_State *L) memset(&val, 0, sizeof(pv_value_t)); if(pv_get_spec_value(env_L->msg, &pvs, &val) != 0) { - LM_ERR("unable to get pv value for [%s]\n", pvn.s); - return 0; + LM_NOTICE("unable to get pv value for [%s]\n", pvn.s); + lua_pushboolean(L, 1); + return 1; } if(val.flags&PV_VAL_NULL) {
