Purging directory: System.IO.PathTooLongException

peter.rodda · April 6, 2017, 2:57pm

We’ve a minor issue where under certain circumstances our app creates a number of folders and files and the path becomes too long. On the subsequent deployment, it causes Octopus to fail to purge the folder when deploying a package:

09:15:46   Info     |       Purging the directory 'E:\WebApp'

Workaround is to simply delete the contents of the folder manually and carry on.

Octopus Server version 3.11.4
Calamari version 3.7.5

Hello,

Thanks for getting in touch. Yes, long paths are not great to deal with, thanks for letting us know you encountered this, it helps us prioritize what issues to work on.

We have an issue in progress to fix this across the various sub-systems of Octopus. But it’s still a work in progress. I appreciate it’s not ideal but if you can just keep going with your manual work around for now.

If you like you can follow along with the progress of the 2 related issues here: https://github.com/OctopusDeploy/Issues/issues/3129 and https://github.com/OctopusDeploy/Issues/issues/2532

Thanks &
Regards,
Nick

Thanks Nick for the quick response, I’ll look out for a fix in a future version.

Like I mentioned, just a minor issue for us that crops up from time to time, but can confuse (or panic) an inexperienced deployer so it would be good to see a resolution.

Thanks again.
