@erikjohnston Hope it is OK to set you directly as the reviewer, but since we've already talked about it a bunch that seemed to make the most sense. This approach seems to work fine for streams that reset, with our assumption that a Please let me know how this looks! |

This will need to be expanded to include additional streams, if it is the right fix.

Yeah, I think this makes sense. Though I wonder if we should just call on_rdata so that we don't duplicate things

@erikjohnston Can you take a look at this again? |

This probably needs a comment, but I'm not really sure what to suggest...
Also call
on_rdatato ensure that stream positions are properly reset.

When processing
RDATAcommands via replication, discard anyRDATAthat has already been seen. This is calculated via asking the stream to get the "current position" and comparing to the incoming token.Fixes #7360
