Carbons doesn't seem to work from one Pidgin instance to another

[rrthomas]

I have Pidgin installed much the same on two Ubuntu machines (2.14.10), and have Carbons installed and activated on both. Carbons only seems to work reliably with one running instance of Pidgin; if I have two, then one of them gets all messages "carboned" from Snikket, but the other doesn't, and neither seems reliably to get messages I send on the other.

Any hints on what I might be doing wrong?

Thanks very much for this plugin and lurch, which together make Pidgin work much better with Snikket.

hi, thank you for your report.

you mean both pidgin instances are running at the same time, right? could you copy the raw xml messages from the debug log of the instance which does not (visibly) receive the messages it should?

if you quit pidgin while the debug window is open, pidgin will start with the debug window open the next time. so you could also check if the feature discovery + activation works.

this is a simple protocol and it has been pretty stable, but sometimes servers change or mangle their replies. i don't really know snikket, do happen to know which server software it uses?

thank you, i appreciate that :slightly_smiling_face:

I'm sorry I've not found time to respond yet: having found various problems with Pidgin and modern XMPP, I switched to Gajim. But I would like Pidgin to improve, so I will find time to get those debug logs!

I can tell you one thing: Snikket is just a repackaging of Prosody (server) and Conversations (Android client).

thank you!

there was in issue with a specific prosody version in the past, however i doubt that snikket would use such an old version on purpose.

Prosody version says (unhelpfully): Snikket release beta.20220119.2

As far as I can tell from the scripts that build Snikket's docker image, it uses the nightly build of Prosody current on the relevant day, which for the date above is somewhere around 0.11.1 to 0.11.2.

I captured a debug log from starting up Pidgin with the Debug window open, and it says "Successfully activated carbons". Is there anything else you need to know on that front?
