[Bug]: MeshChat 2.12.1 Does Not Work with Latest AREDN Nightly Builds

[K5RA]

Contact Details

Version

v2.12.0

System Type

Unknown

What happened?

System 1: meshchat_2.12.1_all.ipk running in a UBNT Rocket XW.
System 2: meshchat-api_2.12.1_all.ipk running in a hAP ac lite with meshchat_1.02_all.deb running in R-Pi 5b service computer

The systems in question are part of a mesh island with about forty AREDN nodes and about 120 devices. Six of the nodes have advertised MeshChat servers. The six nodes with servers are running AREDN firmware stable release 3.24.10.0. All advertised services have service name NEW-NTXChat with no appended service-type icon. The message databases of the six MeshChat servers are synchronized.

When the AREDN firmware of either System 1 or 2 was upgraded to a current nightly build, MeshChat ceased working correctly. Messages originated in the upgraded node would sync to the other five, but messages from nodes running the stable release would not appear on the node running the nightly build. This was demonstrated on one Type 1 system and three Type 2 systems.

Apparently a new version of MeshChat is needed because existing version does not work with the current AREDN nightly builds. The current MeshChat may not be compatible with changes to libraries that are shipped with AREDN and/or with how services are now represented (no longer in flat files). (per KN6PLV)

MeshChat configuration

No response

Connection type

Mesh network connected through IP tunnel

Node names

System 1: K5RA-RK2C-FB. This node is DTD to System 2. System 2: K5RA-HAP-FB with K5RA-RP5B1

What browsers are you seeing the problem on?

Chromium in the RP5B

Below is the patch to get MeshChat working again .. but unfortunately against my repo (https://github.com/kn6plv/meshchat) rather than this one. Hopefully @hickey can extract the changes and apply them here.

I had a few minutes this afternoon to copy the fixes over as a PR against this version. I still dont know how to build this version.
