Re: [sr-dev] Lua sr.pv.get and htable pv problem

Hi,

when using sr.pv.get() in app_lua the pv value is not always returned.

Lua code is:

local fscript = sr.pv.get("$(sht(myscripts=>" .. args["filterid"] .."))")

if(fscript) then
    sr.log("info","Filterscript is " .. fscript)
else
    sr.log("warn","fscript not found!")
end

And log shows:

app_lua [app_lua_sr.c:888]: pv get: (sht(myscripts=>1)) <core> [pvapi.c:318]: pvar [$(sht(myscripts=>1))] found in cache WARNING: app_lua [app_lua_sr.c:99]: fscript not found!

So the pv is being discovered in the pv cache, but sr.pv.get() returns no value.

I think the problem occurs especially in the case, when using sht_reload mi command. So I have had a short look into htable.c and I did not find any code, that clears the pv cache... is that necessary/may the reason for the problem, that pv is found in pv cache but nothing returned? (kamailio 3.2.3)

Thanks for any ideas...

the cache is for PV names, not for PV values. What is printed as value of fscript anyhow? It might get 0 which will result in same logic with IF.
