Lost TXT packets when server is started after client

[flotter]

Hi,

I do not have much experience with DNS-SD, but I have observed a difference in behaviour I cannot explain. Perhaps someone could help me understand this?

1. Working Example:

I start the responder first (which includes TXT key-value fields). After the responder was started (given ample time), I run the client browser with a context with timeout (e.g. 5 seconds).

In this case the browser service reponse includes the TXT fields.

2. Non-working Example:

I start the client first with context timeout 5 seconds. Just one second after the client is started, I start the responder.

In this case the browser is showing the service, but it does not include the TXT key / value data. However, the TXT packets are indeed sent (as I can confirm via wireshark).

Replacing the client/browser with avahi-browse -a -r, shows the results I expect, with the TXT fields populated.

Is this a known issue, or expected behaviour?

This is definitely not a known issue and needs some investigation.
