Description

When using the Python3 extension for KEMI, registrar.save complains about an unknown location: registrar [api.c:44]: regapi_save(): usrloc domain [location] not found. Saving the user location works without problems in the core scripting language.

Troubleshooting

Reproduction

Here is a fairly minimal Python3 script:

import KSR as KSR

def mod_init():
    KSR.info("===== from Python mod init\n")
    return kamailio()

class kamailio:
    def __init__(self):
        KSR.info('===== kamailio.__init__\n')

    def child_init(self, rank):
        KSR.info('===== kamailio.child_init(%d)\n' % rank)
        return 0

    def ksr_request_route(self, msg):
        KSR.hdr.remove('Route')
        if KSR.is_method('INVITE'):
            KSR.rr.record_route()

        if not KSR.is_myself_ruri():
            KSR.info(f'Relaying to foreign domain: to={msg.RURI} method={msg.Method}\n')
            return self.relay(msg)

        if KSR.is_method("REGISTER"):
            return self.registration(msg)
        KSR.registrar.lookup("location")
        KSR.sl.send_reply(100, "Trying")
        return self.relay(msg)

    def ksr_reply_route(self, msg):
        KSR.info(f'Received response: from={msg.src_address} status={msg.Status}\n')
        return 1

    def ksr_onsend_route(self, msg):
        if msg.Type == 'SIP_REQUEST':
            KSR.info(f'Sending request: to={msg.dst_address} method={msg.Method}\n')
        return 1

    def registration(self, msg):
        if not KSR.registrar.save("location", 0x01):
            KSR.sl.sl_reply_error()
        return 1

    def relay(self, msg):
        if not KSR.tm.t_relay():
            KSR.sl.sl_reply_error()
        return 1

If this script is used for request routing, the user locations cannot be saved and the above mentioned error is logged.
