lovetox, the question is now when the monitoring plugin duplicates messages, its when not!

iirc it duplicates the messages n times, where n is the number of people in the MUC

ok what is this plugin for? Is this plugin the MAM implementation?

some clients discard duplicates, so you dont always see them, gajim as we have established in the past is very good at finding bad stanzas, as it ignores nothing :)

theres also an issue with OMEMO and the MAM implementation, sometimes a duplicate message is sent, but OMEMO cant decrypt it

theres also some issue with OMEMO where certain clients (namely dino <--> dino, and dino <--> Monal) cant discover the other clients OMEMO keys, but I think this is down to a PEP issue.

I did want to take a crack at patching this a while back, but MAM is a very big XEP and debugging where this is going wrong would take _ages_

mainly because I dont know the codebase well

are you talking now about Gajim or Openfire

or dino, or monal

im lost a bit

lovetox, sorry I was just explaining the numerous issues Openfire has :D

duplication and OMEMO errors happen on all clients, but not discovering OMEMO keys happen on select clients...

which cant be reproduced on prosody, so its an Openfire problem :p

that a message cant be decrypted twice is not an omemo bug

the root cause would be that you received a message twice, which should not happen

ah yes
