[kamailio 3.1.0]PostgreSQL + Permissions + DRouting: Concurrent db access fault on returning result set

by Giorgio Maria Santini

Hello everybody, We need to deploy kamailio with both drouting and permissions modules enabled. We are using kamailio 3.1.0 and we found, probably, a bug in one of the two modules (we don't know where) that cause kamailio to quit for an invalid table_version founded for table Permissions. First, I want to say that in table version there is the right record: kamailio=# select * from version where table_name='trusted'; LOG: statement: select * from version where table_name='trusted'; table_name | table_version ------------+--------------- trusted | 5 (1 row) Then, debugging I've found that kamailio do the right query, but returns a wrong recordset. Here a little snapshot of the debug: 1(2615) DEBUG: <core> [db.c:294]: connection 0x82bc910 found in pool 1(2615) DEBUG: db_postgres [km_dbase.c:149]: 0x82bc8f8 PQsendQuery(select gwid,address,strip,pri_prefix,type,attrs from dr_gateways ) ... .... 2(2616) DEBUG: db_postgres [km_dbase.c:149]: 0x82a74e8 PQsendQuery(select table_version from version where table_name='trusted') 2(2616) DEBUG: <core> [db_res.c:116]: allocate 28 bytes for result set at 0x82a7598 LOG: statement: select gwid,address,strip,pri_prefix,type,attrs from dr_gateways 2(2616) DEBUG: db_postgres [km_dbase.c:403]: 0x82a74e8 PQresultStatus(PGRES_TUPLES_OK) PQgetResult(0x870c010) 2(2616) DEBUG: db_postgres [km_res.c:108]: 6 columns returned from the query instead of saying "1 columns returned from the query" it returns the number of columns of the query launched in the other thread, I think. In this case "select gwid,address,strip,pri_prefix,type,attrs from dr_gateway" but it's not always the same query, sometimes returns the query of the usrloc, or other else. The strange is that it's happen only when Permissions and Drouting modules are enabled together. If I remove one of this, not depending on which one I choose, everything works ok. We absolutely need both modules working together, but this errors (a bug??) destroys our dreams of success :) Here is the complete log: 0(2614) DEBUG: db_postgres [km_pg_con.c:72]: opening connection:

about contact params

by Juha Heinanen

i noticed that if i add ;alias param to contact header that does not surround its contact uri in <>s like this: Contact: sip:foo@bar;alias=value then some sip entities interpret ;alias as header param rather than uri param. so i went and added <>s if they are not present resulting to this: Contact: <sip:foo@bar;alias=value> i have tried to figure out from rfc3261 what kind of param ;alias is in the first example, but have not found the answer. looks like it is unspecified in rfc3261. any comments on this? -- juha

[tracker] Comment added: $Ts returns wrong timestamp

by sip-router

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. The following task has a new comment added: FS#105 - $Ts returns wrong timestamp User who did this - Alex Hermann (axlh) ---------- Ok, that explains the first case in technical terms. Logically i still find it strange the $Ts in failure_route is not the same as the one in request_route because it is supposed to handle the same message/request. The 2nd case of the timestamp being from an entirely different message is a bit more worrying. Besides the annoyance of the wrong timestamp, I fear the timestamp may not be the only variable not correctly being cleared/initialized when a fake reply is created. I still haven't dared to look into tm though, so can't say for sure. ---------- More information can be found at the following URL: http://sip-router.org/tracker/index.php?do=details&task_id=105#comment140 You are receiving this message because you have requested it from the Flyspray bugtracking system.

[tracker] Comment added: $Ts returns wrong timestamp

by sip-router

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. The following task has a new comment added: FS#105 - $Ts returns wrong timestamp User who did this - Daniel-Constantin Mierla (miconda) ---------- The caching is done based on message id and process handling the message. So it should be same value for a request all along to forward in a route block. But for failure_route can be another process, therefore it is different except a very unlikely case when it is same process that did the forward and was no other message processed there meanwhile. Also, reply processing in onreply route is a different message than reprocessing request again in failure route even due to that reply. There is a small potential of overlapping because of using only message ids for caching (this is not only for $Ts) -- there were some discussions to add PID as part of the ID for a better message unique key. if you need the time of the moment when the request was received, the option is to store it in avp. ---------- More information can be found at the following URL: http://sip-router.org/tracker/index.php?do=details&task_id=105#comment139 You are receiving this message because you have requested it from the Flyspray bugtracking system.
