heaps of ebt ValidateNext() errors

[ahdinosaur]

hi :smiley_cat:

i tried upgrading from the node pub to the go pub: https://github.com/cryptoscope/ssb/issues/121

i used ssb-offset-converter, but seems ebt replication isn't working, there's a repeating pattern of error messages.

logs snippet:

i tried removing the logs and re-sync-ing from just the secret and a manual connection, but that didn't seem to work either..

okay, starting over and disabling ebt seems to be working. but i hope i'm just doing something wrong.

tried again with a converted db (after using legacy replication for a time), no luck:

go-sbot.log

Hi @ahdinosaur!

I can't speak for @cryptix, but if I remember correctly EBT was very experimental before the NGI project started. I believe it was significantly improved upon over the course of the project, but as you've been noticing, there might be more to do.

It feels bad to send you on a wild goose chase, but I figure I should mention that there's a still open PR that might have some fixes on the EBT front: https://github.com/cryptoscope/ssb/pull/111

Wish I could help you more, but I never touched the EBT guts; I'm but a fledgling gopher in this project 👶

fwiw the pub that I tried to migrate from node-pub to go-pub is also still not working (https://github.com/cryptoscope/ssb/issues/126). Maybe I should try disabling EBT for it as well (or maybe its an unrelated issue)

[cryptix]

That's odd... I haven't seen these in a long time and not from clean slate...

@ahdinosaur can you try running with -fsck sequence? If that finds any error you need to run that again with -repair, too.

If it doesn't find a problem with any of the feeds, please try deleting the ebt-state-matrix folder in the repo ($HOME/.ssb-go by default)
