[QA] Windows VFS tries to hydrate excluded filenames and fails

[jnweiger]

Seen with ownCloud client 2.7.0 RC3 on windows 10 using VFS.

• With the web UI on the server create a folder 'Music', with a few files in them. (PNG files in my case)
• wait until sync finishes.
• Make sure the status column of the folder shows a cloud. If needed click and and choose 'Free up space'
• on the client rename the folder to one of the excluded filenames. e.g. Music~
• the folder gets removed from the server. BAD. The contents is lost now. See [QA] renaming a dehydrated folder to an excluded name leads to data loss #8217
• enter the folder, click open a file.

Windows tries to connect the owncloud client for the contents of the file and fails after a timeout:

Expected behaviour: an excluded file should always be exclude in fully hydrated state only. (Or alternatively, the exculded files list is not applied for renames. )
The file is always available locally.

After the rename to the excluded pattern the the files are removed from the sync set, meaning they are deleted on the server and the placholders are invalid.
TODO:

• Improve the error message.
• Add documentation
