Lua sr.pv.get and htable pv problem
by Jasmin Schnatterbeck 14 Mar '13

14 Mar '13

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... Cheers Jasmin

massive SQL load and one subscriber only with presence 3.3
by Jasmin Schnatterbeck 14 Mar '13

14 Mar '13

Hi, in kamailio 3.3 the presence DB mode parameters "subs_db_mode", "publ_cache" and "notifier_processes" control how the module stores presentity and watcher info in DB. If they have been set to the following values: subs_db_mode=3 publ_cache=0 notifier_processes=3 the following query is executed >10 times/second (mysql log): "select presentity_uri,callid,to_tag,from_tag,event from kamailio_active_watchers where updated=123 AND event<>'presence.winfo'" According to the notifier_poll_rate default value (==10) and the formula in the documentation 1/(waitn_time * notifier_poll_rate * notifier_processes) That results in 1/(5*10*3) == 1/150 So is it really regular behaviour, if the query is performed that often? What about using triggers in that situation? Additionally I have noticed, that only one subscriber gets notified, if a presentity changes although all subcribers have been stored correctly in active_watchers. When I set notifier_processes to 0 (old behaviour) every subscriber gets notified correctly... Cheers Jasmin

MySQL max index length and DB structure
by Jasmin Schnatterbeck 14 Mar '13

14 Mar '13

Hi, when upgrading to kamailio 3.3 I have noticed, that in the database structure new indexes are present (e.g. in presence module). The problem is, that some of those indexes are too long for mysql, if the DB charset is utf8 (mysql calculates several bytes per character): "Specified key was too long; max key length is 1000 bytes". This is a very well-known limitation in mysql: http://bugs.mysql.com/bug.php?id=4541 ... and I think we can not expect this behaviour to be changed in future versions of mysql (at least that is what comments like "redesign your table" or "table design is bad" indicate). Not using utf8 at all is (in my opinion) not really a solution. That means, that mysql-support for the DB structure is somewhat limited...? What about MariaDB as an alternative? Cheers Jasmin

What is ICE ?
by Khoa Pham 14 Mar '13

14 Mar '13

Hi, AFAIK, ICE is used to detect as many ways as possible to send media stream to the other client. If it can't find, it will use TURN protocol to determine media relay proxy. How can ICE detect many ways? Can we benefit from ICE if we're in symmetric NAT? -- Khoa Pham HCMC University of Science Faculty of Information Technology
