[Perforce] Unity fails to checkout project assets

Version Control


To Reproduce:

1. Put attached project inside a workspace & set up a connection to Perforce.
2. Submit everything in the default changelist.
3. Click Connect.
4. Quickly open scene "main".
5. Unity will be in a state where it doesn't automatically checkout a scene if saved and other assets such as materials can be edited and saved without first needing checkout.
6. If you leave the project open, after a few minutes Unity will return to a working state where assets can be checked out properly.

    Getting an error from P4 Connect. P4 Connect says the following files could not be checked out. I cannot check out the files with in Unity with the P4 Connect tools. If I check out the files in P4, I still get the error message in Unity.

    I think this is still happening in 5.3.1. I have to check out the file scene in the project window.

    A fix is ready and will be in an upcoming 5.1 patch release.

    I've had a similar issue since I started using Perforce with Unity 4.5, and issues still persist today with Unity 5.1. However, it's not just related to scene files ... sometimes unity just simply makes a prefab editable in the inspector without checking out the file from perforce, and no version control operations can be done on the prefab.

    I get this as well:

    Every time I start, I get "Cannot set mode of files in offline mode" followed by "User XXXX logged out. (level 48)"

    Finally, there is a console message saying "can't add existing file (level 48)" about all of the files in the ProjectSettings folder.
