Transactions are corrupted when server restarts

[tathougies]

I'm on v0.10.0 from git.
I'm running a simple cluster of 3 VMs (although i see the same problem when running locally on different ports). I'm using the builtin UV TCP transport.
When I take a node down and bring it back up, the first X bytes of a transaction are cut off. If I examine the open-1 file of the node I take down, it contains the full transaction data, but when I restart the node, the transaction is corrupted.

Any ideas? How would I debug?

I read through the code. There is this comment on line 740 of uv_segment.c:

        /* TODO: enforce the requirement of 8-byte alignment also in the
         * higher-level APIs. */

That would have been really good to know. Even a comment in the docs somewhere, or a hard failure, would have made this way easier to debug. Everything seems to work now.

@tathougies Thanks, we'll keep it in mind for future improvements. Can I close this?

[tathougies]

Yes. you can close this. Something that would pad/unpad automatically would be good. Otherwise, an error code should be returned
