liaodn opened a new issue, #226:
URL: https://github.com/apache/bifromq/issues/226
In the local non shared subscription path, when a local route exists but the
corresponding session is missing or not an `IMQTTTransientSession`,
`LocalDistService.dist` does not write a result entry for that `MatchInfo`.
This causes upstream `BatchDeliveryCall` to log repeated `No deliver result`
warnings.
Expected behavior is to return `NO_RECEIVER` and always include a result
entry.
Example log:
```
2026-02-04 22:23:14.338 WARN ... BatchDeliveryCall
[BatchDeliveryCall.java:137] No deliver result: tenantId=tffffffff,
route=matcher {
filterLevel: "#"
mqttTopicFilter: "#"
}
receiverId: "1000061147400331990937"
incarnation: 1147400331990937
, batcherKey=DelivererKey[subBrokerId=0,
delivererKey=cb3564ba-7c07-4e92-bfcb-8c5839ee9a01/1672626574:tffffffff:2]
```
### **Reproducible Steps**
1. Start a single node BifroMQ without any custom plugins
2. Create a local non shared subscription route, for example subscribe to
`#`
3. Disconnect the corresponding client session so the session is missing or
not an `IMQTTTransientSession`
4. Publish a message that matches the route
5. Observe repeated `No deliver result` warnings in logs
**Root cause**
In the local route branch of `LocalDistService` where missing or non
transient sessions do not generate a result entry.
