[kamailio/kamailio] Ability to reload location attributes at runtime (#2299)
by Sergiu Pojoga 26 Aug '22

26 Aug '22

### Description Looking for a mechanism to reload Location attributes at runtime. Having both registered and permanent Contacts under AoR, with Attributes from `usrloc` to be used for various routing decisions. This is about attributes of permanent Contacts. Registered ones have `xavp_contact` of `usrloc` to store attributes during registration. **Problem:** Only way to make it work is: 1. adding a permanent Contact using `rpc ul.add` 2. assigning attributes in DB `location_attr` per RUID (can't find an rpc function for attributes) 3. restart Kamailio modparam("usrloc", "db_mode", 1) modparam("usrloc", "db_load", 1) This however is far from ideal, having to restart Kamailio for every change in attributes of a Contact. ### Expected behavior #### Actual observed behavior #### Debugging Data ``` (paste your debugging data here) ``` #### Log Messages  ``` (paste your log messages here) ``` #### SIP Traffic  ``` (paste your sip traffic here) ``` ### Possible Solutions  ### Additional Information * **Kamailio Version** - output of `kamailio -v` version: kamailio 5.3.3 (x86_64/linux) 44ccb9 * **Operating System**:  ``` (paste your output here) ``` -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] keep new features in a file in the repository (#668)
by Victor Seva 26 Aug '22

This will allow us to point https://www.kamailio.org/wiki/features/new-in-devel to the file and "force" developers to update that file with the new features when they are introduced in the repository Remaining developers to upgrade the wiki seems pointless and anyone can create a PR for changes --- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] kazoo: consuming of events fails if message has no body (#1837)
by mihovilkolaric 26 Aug '22

26 Aug '22

### Description Consuming messages without message body fails due to a JSON parsing error: ``` ERROR: kazoo [kz_json.c:287]: kz_json_parse(): Error parsing json: unexpected end of data ERROR: kazoo [kz_json.c:288]: kz_json_parse(): ERROR: kazoo [kz_amqp.c:2960]: kz_amqp_send_worker_event(): error parsing json body ``` This makes it unable to consume messages from RabbitMQ's event exchange plugin ( https://www.rabbitmq.com/event-exchange.html ), as the documentatin states: **"The message body is always blank."** ### Possible Solutions As a possible fix I tried following change in kz_amqp.c: ``` void kz_amqp_send_worker_event(kz_amqp_server_ptr server_ptr, amqp_envelope_t* envelope, kz_amqp_bind_ptr bind) { char buffer[100]; kz_amqp_cmd_ptr cmd = NULL; kz_amqp_consumer_delivery_ptr ptr = NULL; json_obj_ptr json_obj = NULL; json_object* JObj = NULL; str* message_id = NULL; int idx = envelope->channel-1; int worker = 0; int _kz_server_id = server_ptr->id; int msg_size = envelope->message.body.len; //begin of changes int routingkey_size = envelope->routing_key.len; if (msg_size == 0 && routingkey_size > 0 ) { char *routingkey_data = pkg_malloc(routingkey_size + 1); memset(routingkey_data, 0, routingkey_size + 1); memcpy(routingkey_data, (char*)envelope->routing_key.bytes, routingkey_size); LM_DBG("Message size: %d\n", msg_size); LM_DBG("Routing Key: %s\n", routingkey_data); char *pos = strchr(routingkey_data,'.'); while (pos){ *pos = '_'; pos = strchr(pos,'.'); } LM_DBG("New Routing Key: %s\n", routingkey_data); sprintf(buffer, "kazoo:%s", routingkey_data); if(kz_amqp_consumer_fire_event(buffer) != 0) { LM_ERR("kazoo:%s not found", routingkey_data); } pkg_free(routingkey_data); return; } char *json_data = pkg_malloc(msg_size + 1); if(!json_data) { LM_ERR("no more package memory available. needed %d\n", msg_size + 1); return; } char *json_data = pkg_malloc(msg_size + 1); //end of changes if(!json_data) { LM_ERR("no more package memory available. needed %d\n", msg_size + 1); return; } ``` The change is rather simple: If there is no message-body supplied, the event-route _kazoo:<binding_key>_ is called (after replacing any '.' with '_' in the routing_key). -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] kamctl - maintenance for dbtextdb.py tool (#2469)
by Daniel-Constantin Mierla 24 Jun '22

24 Jun '22

**kamctl** include a python tool that is parsing SQL statements to do operations over the **db_text** files, for the common db operations (e.g., insert, delete). It is located at: * https://github.com/kamailio/kamailio/tree/master/utils/kamctl/dbtextdb The tool was contributed long time ago and not kept up to date, being known not to work with Python3 (e.g., #2464). This issue is created to see if someone has the interest to pick up the maintenance of this tool, if not it will be removed from kamctl. Note that db_text works with text files, so it is not necessary to have a tool for managing the content of these files, they can be simply updated with any text editor. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] [kamctl] Dispatcher operations in a case of db_text are mostly incorrect (#2464)
by Igor Olhovskiy 24 Jun '22

24 Jun '22

### Description On creating dispatcher with `kamctl` in the case of `db_text` it fails ### Troubleshooting #### Reproduction Point `kamctlrc` to DB_TEXT. Run `kamctl dispatcher add 1 sip:asterisk_2:5060 1 3` Run 'kamctl dispatcher add 1 sip:asterisk_2:5060 1 3 'prefix=123' 'test1'' Run 'kamctl dispatcher show' Run 'kamctl dispatcher reload' #### Debugging Data ``` # kamctl dispatcher add 1 sip:asterisk_2:5060 1 3 attrs cannot be empty or null -e \E[37;31mERROR: dispatcher - SQL Error ``` ``` # kamctl dispatcher add 1 sip:asterisk_2:5060 1 3 'prefix=123' 'test1' Traceback (most recent call last): File "/usr/lib/x86_64-linux-gnu/kamailio//kamctl/dbtextdb/dbtextdb.py", line 1243, in <module> main(sys.argv) File "/usr/lib/x86_64-linux-gnu/kamailio//kamctl/dbtextdb/dbtextdb.py", line 1230, in main dataset = conn.Execute(' '.join(argv[1:])) File "/usr/lib/x86_64-linux-gnu/kamailio//kamctl/dbtextdb/dbtextdb.py", line 423, in Execute self.WriteTempTable() File "/usr/lib/x86_64-linux-gnu/kamailio//kamctl/dbtextdb/dbtextdb.py", line 1138, in WriteTempTable self.temp_file.write(header.strip() + '\n') File "/usr/lib/python3.7/tempfile.py", line 620, in func_wrapper return func(*args, **kwargs) TypeError: a bytes-like object is required, not 'str' -e \E[37;31mERROR: dispatcher - SQL Error ``` dump is showing active dispatchers, show - is not. ``` # kamctl dispatcher dump { "jsonrpc": "2.0", "result": { "NRSETS": 1, "RECORDS": [{ "SET": { "ID": 1, "TARGETS": [{ "DEST": { "URI": "sip:asterisk_2:5060", "FLAGS": "AP", "PRIORITY": 0 } }] } }] }, "id": 124 } root@e529c8cb4f62:/# kamctl dispatcher show -e dispatcher gateways ``` No result on reload ``` # kamctl dispatcher reload { "jsonrpc": "2.0", "result": { }, "id": 160 } ``` ### Possible Solutions I've tried to add data to the table manually, but here I got another issue.

[kamailio/kamailio] [Feature Request] Add reload capability for geoip2 module (#2029)
by Joel Serrano 13 Apr '22

13 Apr '22

### Description Currently, the `geoip2` module loads the IP database at startup and keeps it in cache and there is no way to tell Kamailio to reload the database without a full restart. ### Possible Solutions To keep this module inline with other modules that use external datasources, I would suggest to implement a new RPC command and a new geoip2 function to reload the database defined in the `path` geoip2 modparam without the need of a restart. I'm not aware of the effort required for implementing either of them, but only having an RPC command would effectively solve this issue as you can call RPC commands from within Kamailio conf, thus, the reload function would not be something strictly required but more of a nice-to-have. ### Examples: Function: ``` geoip2_reload() ``` RPC command: ``` kamctl rpc gip2.reload / kamctl rpc geoip2.reload ``` Kamcmd command: ``` kamcmd geoip2.reload ``` -- You are receiving this because you are subscribed to this thread.
