Hello, I once again lost a (precious) file to this bug (using leafpad with gvfs over sftp) ðŸ˜.
( gvfs 1.28.2 , leafpad 0.8.17 , debian 8 or ubuntu xenial ) Leafpad is just the trigger here. as the behavior of gvfs+sftp differs from the local ext4 file system, it could cause some data loss in other software. Reformulation of the bug: if some data written to a stream file pointer are still not flushed before opening+closing a second stream file pointer on that same file, the flushing of remaining data on the first file pointer will : - succeed on a local ext4 filesystem. - fail when using gvfs+sftp (over a remote fs, or even over the local fs) with EOPNOTSUPP error code @Max Rockatanski: I think I will create a new bug report specifically for leafpad
