Not terribly helpful perhaps, but in using the channel API I always had to build in polling backups because it wasn't uncommon at all for messages to not be received. Presumably the chat messages are stored somewhere, so how about adding a timeout such that if the client doesn't receive a message within N seconds, poll for any missed messages? Maybe it's just me, but I never considered the channel API to be very robust. Tokens randomly didn't work, exceptions were raised from the library for seemingly no reason, etc. I just use it as a tool to drastically cut down on Datastore queries, not as the foundation of an application. > > cheers, > Aleksei > > -- > You received this message because you are subscribed to the Google Groups > "Google App Engine" group. > To view this discussion on the web visit > https://groups.google.com/d/msg/google-appengine/-/4PMdsL9OPJIJ. > To post to this group, send email to google-appengine@googlegroups.com. > To unsubscribe from this group, send email to > google-appengine+unsubscr...@googlegroups.com. > For more options, visit this group at > http://groups.google.com/group/google-appengine?hl=en. > -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
