[Serusers] ser-0.9.6: modules/postgres bugreport & patch
by Alexandre Snarskii 13 Oct '08

13 Oct '08

Hi! I'm running ser-0.9.6, on FreeBSD 6.1-stable, database backend is postgresql version 8.1.3. Today I got errors in logfiles, saying: messages.2.bz2:May 29 14:35:03 <XXX> /usr/local/sbin/ser[51448]: ERROR:avpops:dbrow2avp: dbrow contains NULL fields The similar problem reported in: http://lists.iptel.org/pipermail/serusers/2005-May/019681.html with much more detailed description of error, database contents and config samples. Patch is trivial, and looks more like a fix to copy'n'paste error: in mysql/val.c function str2val states: if (!_s) { memset(_v, 0, sizeof(db_val_t)); VAL_TYPE(_v) = _t; VAL_NULL(_v) = 1; return 0; } VAL_NULL(_v) = 0; and the last line mentions that 'well, that's value is not NULL'. In postgresql/db_val.c, line 182, function str2valp, the same statement is the: if (!_s) { DLOG("str2valp", "got a null value"); VAL_TYPE(_v) = _t; VAL_NULL(_v) = 1; return 0; } without explicit notification that this is not-NULL value. More than, nowhere else in this function VAL_NULL(_v) not set to 0. So, if a value _v.val contained anyting but 0 at the function start, resulting value will be threated as NULL despite the fact, that _s is NOT NULL. Patch is obvious, just add VAL_NULL(_v)=0; after cited block (line 188) and everyting will be ok. At least for me it's ok for some hours :)

[Users] failure route doubts
by Jose Silva 27 Oct '06

27 Oct '06

Hi, I'm having some doubts on how to use/do some things with dispatcher module and failure route. I'll try to explain my problem. On my main route block I select the destination (using ds_select_dst) to where I want to send the message, and indicate that responses should pass through the failure_route, I also add a header with some things that are needed by the next proxy. On the failure route when I get 408 Time Out I mark the previous destination and select the next destination. until here everything goes fine. After this I want to change the message that I'm going to send to next proxy, for this I need to remove the header that I inserted previously on the main route block and access the destination URI that the ds_next_dst updates. My first doubt is that when I print the destination URI it has the previous destination ( the one used in the main route block) but when it relay's the message it goes to the right destination (the one returned from ds_next_dst), Is there any reason for this ? I'm using $du to access it, is this wrong? My second doubt is, what sip message do I have access to in the failure route (the one I received or the one I sent out)? I ask this because I try to remove the header I inserted in the main route block and it does not remove anything but when I relay the message the header I tried to remove goes on the message. Thanks in advance, José Carlos Silva

[Serusers] Carrier-grade framework for SER
by Andreas Granig 27 Sep '06

27 Sep '06

Hi guys, I'd like to propose another possibility for a highly-available and scalable system design based on SER: The problems I've encountered for scalable systems are: - Distribution of the user location and alias location among the nodes (user location is based on registrations, alias location comes from web interfaces and is used for call forwarding). - Reloading up to date location tables after breakdown and recovery of a node So I'm just thinking loud about the following provisioning system: - Write a client which fulfills the this demands: - Receive one or more locations from SER via a SER module or from a web application and distribute them to other known clients. Take care of retransmissions if a client isn't reachable or reports a temporary failure. - Receive one or more locations from other clients and write them into the SER FIFO. If writing into the FIFO fails, try to write directly into the database (location-table, alias-table etc.). Report a temporary failure if this also fails. Maybe a centralized server should be used which receives the locations from the clients and distributes them to other clients, so that the nodes just know about the server and nothing about other nodes. This would make integration of new nodes easy. On the other hand, it's another single point of failure, so a decentralized solution should be considered. But that would mean that you've to inform every node about the existence of a new node. The protocol used between the nodes should be simple and fast. So I think SOAP drops out here. Maybe XMLRPC or ICE (http://www.zeroc.com/ice.html) could be used. One might think now why not just use replication on SIP layer, but t_replicate only supports one peer and you've no possibility to get locations on a node while it's down. Replication of other location tables like the alias-table is also not possible. I'd be willing to release these parts as GPL for creating an open framework for carrier-grade SER integration, so any feedback, improvements or flames are highly welcome. Cheers, Andy

[Users] Using subst() of Textops module
by Leonid Fainshtein 29 Aug '06

29 Aug '06

Hi, In the textops module doc (http://openser.org/docs/modules/1.0.x/textops.html#AEN124) there is an example that demonstrates how to replace URI in the header "To" with the message URI: # replace the uri in to: with the message uri (just an example) if ( subst('/^To:(.*)sip:[^@]*@[a-zA-Z0-9.]+(.*)$/t:\1\u\2/ig') ) {}; After I've fixed a small mistake (instead of /t: I put /To:) it worked. But I don't understand how does it work. It looks like "u" is substituted by URI from R-URI but I didn't find such core variable. Could somebody explain me? Thank you in advance, Leonid Fainshtein

R: R: [Users] using AVPs to write into database

Thanks, I've looked into but it works only with 1.1.x version...!!! What's the different with avp_db_store command, may I use it to store something in my SQL DB? I'll try to do but I have some problems, he doesn't register... I have another question: I need to work over sdp messages, is possible to do a parsing, always using the scripts language...? Any thought?
