Did you check what happens with the dispatch fiber when it gets a message during migration?

It shouldn't? The connection migrates, before it does it joins the dispatch_fb_
. At this point we got no messages and we are the active fiber on the thread we are executing. Then we suspend on the current thread and we continue our execution on the thread we migrate. During that time the dispatch_fb_
should stay joined
(that is, it couldn't be restarted) since no other operation can or should really wake it -- thinking of ACL's here(since the connection won't even show up when it gets removed by the thread local connection table and when it becomes available again on the thread local of the migrated thread it will be the active fiber - so no other fiber can wake up its queue).
Am I missing something?

Theoretically... we check that no subscriptions are active when we migrate and no command is ongoin, so there shouldn't be any, right.
We have this dcheck to catch it if it does. Maybe there will be a reason do so in the future and we'll forget this is a potential bug 🙂

@kostasrim @dranikpg it is a bug.

can SendAsync
be called from another connection? In that case it would kick off the fiber. Correct @dranikpg ?

can SendAsync be called from another connection?
Sure it can, pubsub as an example. I had a feeling that's something's wrong here, that's why I asked.
We migrate only when we don't have any subscriptions. The question is whether ACL messages or checkpoint messages see us on the new or old thread during migration

We should
check this -- I can -- but once I wrap up the current staff.
can SendAsync be called from another connection?
Both connection fiber and dispatch fiber run on the same thread so during a migration the connection fiber is active
so SendAsync
should happen after
the migration and therefore it should have the correct semantics?
Maybe I am missing something... Either way we have a track record of having issues around this code and we should take care of it.
I will ping here once I get a chance

It could be that the Fiber is migrated but was not switched to yet. Meanwhile another producer-fiber find the connection on a new thread and calls SendAsync. The migrated fiber finaly resumes and finds out its dispatch_fb_ has started. Seems like a valid scenario.
