[SR-Users] htable + event_routes + mod-init + htable:expired

[Brandon Armstead]

Daniel,

   In short kamcmd does not reflect the value set in $sht(server=>auth
::token)

It alternates between being set and not being set (reflecting in kamcmd
htable.dump

root at main:/etc/kamailio# kamcmd htable.dump server

{

entry: 11

size: 1

slot: {

{

name: auth::token

value:
{"data":{"token":{"token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJDUllZIiwiaWF0IjoxNjA0MzQ2NzgzLCJleHAiOjE2MDQzNTAzODMsIm1ldGhvZCI6InBvc3Q6YXV0aDp0b2tlbiIsImFjY291bnQiOnsiaWQiOiIxIiwiZmlyc3RuYW1lIjoiVGVzdCIsImxhc3RuYW1lIjoiQXJtc3RlYWQiLCJlbWFpbCI6ImJyYW5kb25AY3J5eS5jb20ifSwic291cmNlIjp7ImFkZHJlc3MiOiIzNC45NC4xMjMuMTIxIn19.aFGWqQg31oNnw10XfZ61Xm5Jncvt7RoNri2ZuDJ6yLQ","header":{"alg":"HS256","typ":"JWT"},"payload":{"iss":"CRYY","iat":1604346783,"exp":1604350383,"method":"post:auth:token","account":{"id":"1","firstname":"Test","lastname":"Armstead","email":"

type: str

}

}

}


In the kamailio logs it always shows AUTH_TOKEN_RECEIVED (correctly, with
the correct auth token), kamcmd dump of htable alternates between execution
of this route: htable:expired:server

Exec 1:

auth::time => [timestamp]

Exec 2:

auth::token => token

Exec 3:

auth::time => [timestamp]

So on and so forth, [ kamcmd htable.dump server ] it does not correctly
hold both $sht(server=>auth::time) and  $sht(server=>auth::token) like it
should, despite kamailio logs showing the HTTP_AUTH_TOKEN received message
with the correct auth token (100% of the time).

It's almost like there is a race condition when using the modules
http_client_query in both init and expired event route.

When I changed it to the resolved code block above separating the calls and
introducing http_async_client inside htable:expired:server

The result is 100% of the time auth token exists correctly, just like the
logs 100% of the time show the auth token received regardless of
event_route implementation.

So somewhere somehow the problematic config causes the hash table to not
store HTTP_AUTH_TOKEN it receives and logs.
