Hi guys,

we have following octodiff warnings during deployment.

Any ideas why this is happening and how critical is it for deployment?
Server and tentacles version: 3.3.14

Hi Vladimir,

Thanks for geting in touch! Octodiff is our delta compression library. The delta compression is used to minimise the size of files being sent to tentacles during deployments.
http://docs.octopus.com/display/OD/Delta+compression+for+package+transfers

As for what could be causing this issue, is it possible that an antivirus could be scanning the file as it is being created?

It is not too critical for your deployment if Octodiff is not run, you could turn it off if you do not want to see the error, it will make new package deployments slower.
If you wish to turn this feature off, create the project variable Octopus.Acquire.DeltaCompressionEnabled and set its value to False

Looking forward to hearing from you. :slight_smile:

Best regards,
Daniel

Hi Daniel,

Thank you for reply.
We reviewed doc for Octodiff (https://github.com/OctopusDeploy/Octodiff)
Here is

Usage: Octodiff signature <basis-file> [<signature-file>] [<options>]
Arguments:
      basis-file             The file to read and create a signature from.
      signature-file         The file to write the signature to.

so arg should be signature-file, but in logs we have

 "C:\Program Files\Octopus Deploy\Octopus\Octodiff.exe" signature "C:\Octopus\Packages\efc\efc.9.13.0.127.nupkg" "C:\Octopus\OctopusServer\PackageCache\efc.9.13.0.127.nupkg.octosig.partial" --progress

used just signature and exit code 4 also confirm wrong argument.

Any ideas how could it be fixed?

Hi Vladimir,

I have investigated this a little further.
It appears the problem is that octodiff.exe is being supplied with a partial signature file. i.e. C:\Octopus\OctopusServer\PackageCache\efc.9.13.0.127.nupkg.octosig.partial.

This shouldn’t happen. I have raised an issue, which you can watch.
We’ll get this resolved as soon as we can.

Apologies for any inconvenience.

Regards,
Michael
