Fork on a feed.

[wanderer]

from here

Which is also causing #321 for me on missing posts.

[pfrazee]

Did the script I posted resolve it for you?

[wanderer]

No, I didn't see the script you posted!

[wanderer]

I think @du5t must of commented on that thread. If he did, it seems like I miss messages that come after du5t comment.

[pfrazee]

He did, but it should just show up as a gap in the thread, not as the end of the thread. Can you post a screenshot of what you see at the end of that thread?

[wanderer]

Here you go @pfraze Do you see my last message on the feed?

[pfrazee]

Hmm. This is worrisome. I havent received those latest messages from you, and you haven't received my latest either.

Can you run sbot getLatest @hxGxqPrplLjRG2vtjQL87abX4QKqeLgCwQpS730nNwE=.ed25519 and show me the output? That will show my last message.

[wanderer]

I get

Ok, that's correct. I was concerned you might be getting more incorrect hashes.

@dominictarr is it possible that the replication failure on dust's feed is causing @wanderer's entire gossip flow to halt? Would one feed's failure abort the entire connection?

@wanderer I'll give you the script here, to fix the issue with dust. Then we'll see if you catch up across the board.

https://gist.github.com/pfraze/c679c4b601c78e194302

Stop patchwork/sbot, back up your ssb directory, put this script in your scuttlebot directory, and then run

node delete-msg.js "%vyyVmWprqjKPtcjw9nB1w0pmld+m41rQp/4pvM5yNw4=.sha256"

If everything looks correct, add --do-it. If you see any errors prior to do-it (which you might) copy them here for me.

[pfrazee]

I just read your last comment in that screenshot, and that's an interesting theory. @dominictarr make sure you see that.

[wanderer]

hmm the script doesn't seem to work. It looks like it deleted Du5t messages, but then when it resynced the message with "key": "%vyyVmWprqjKPtcjw9nB1w0pmld+m41rQp/4pvM5yNw4=.sha256" cames back. And none of dust's message after that sync.

[pfrazee]

No kidding. That's very interesting. Is it possible you're still using the JS version of chloride?

[wanderer]

nope but im using node -v v6.0.0-pre. I got chloride to compile successfully with it.

[pfrazee]

This suggests there's some codepath or condition which causes the hash-miscalculation to happen consistently. If you look at the message that you received after delete, does it look 100% the same as before?

[wanderer]

yep it looks exactly the same

@pfraze what do you get for message %VBfEJjeNUlxLuK0eyRzVha3TLu5PPWLwsvGgnmAdPas=.sha256 ?
