Read-only files not deletable on Windows #1610
Description
I was syncing some files from a Linux machine to the Windows 8 host, then deleted some of those files again.
The log on the Windows machine turned up these errors:
[GUEL3] 22:27:05 INFO: Puller (folder "Photos", file "2012\\08\\04\\124620.jpeg")
: delete: remove C:\Users\Fred\Photos\2012\08\04\124620.jpeg: access denied
[GUEL3] 22:27:05 INFO: Puller (folder "Photos", file "2012\\08\\04\\124628.jpeg")
: delete: remove C:\Users\Fred\Photos\2012\08\04\124628.jpeg: access denied
[GUEL3] 22:27:05 WARNING: Folder "Photos" isn't making progress - check logs for
possible root cause. Pausing puller for 1m0s.
I could delete those files manually using the Windows explorer, but trying to run del in a cmd window gave an error too:
> del C:\Users\Fred\Photos\2012\08\04\124628.jpeg
C:\Users\Fred\Photos\2012\08\04\124628.jpeg
Access is denied.
Turns out, that on Windows, you cannot simply delete files having the READONLY flag set. See the discussion here: golang/go#9606
Basically, you would have to remove the read-only attribute prior to trying call os.remove.
