Description

Configured the location module to load the expires column as a datetime instead of an integer but db_redis ignored the parameter and loaded the data with the default schema. As of today, the default schema has last_modified and expires columns as integers but stores them as timestamps.

id/int,ruid/string,username/string,domain/string,contact/string,received/string,path/string,expires/**int**,q/double,callid/string,cseq/int,last_modified/**int**,flags/int,cflags/int,user_agent/string,socket/string,methods/int,instance/string,reg_id/int,server_id/int,connection_id/int,keepalive/int,partition/int,

Troubleshooting

Reproduction

Use db_redis as backend and use the location module.

While handling INVITE:

if (!lookup("location")) {
sl_send_reply("404", "User Not Found");
return;
}

While handling REGISTER:

if (!save("location"))
sl_reply_error();

Possible Solutions

I patched the default schema with the following and it worked.

id/int,ruid/string,username/string,domain/string,contact/string,received/string,path/string,expires/**timestamp**,q/double,callid/string,cseq/int,last_modified/**timestamp**,flags/int,cflags/int,user_agent/string,socket/string,methods/int,instance/string,reg_id/int,server_id/int,connection_id/int,keepalive/int,partition/int,
