Chris Nauroth updated HADOOP-9043:
----------------------------------
Attachment: HADOOP-9043.trunk.4.patch
Here is version 4 of the trunk patch, with the following changes since last
time:
# {{RawLocalFs#getPathWithoutSchemeAndAuthority}} now returns {{File}} instead
of {{String}}.
# Added comment in {{TestLocalFSFileContextSymlink}} stating that dangling
symlinks are not supported on Windows.
# Added tests in {{TestWinUtils}} for asserting that winutils symlink will
return an error if attempting to pass it paths with forward slashes in either
link or target. The earlier version of the symlink.c patch only checked
target, so I also changed that to check both link and target.
How does this look? Once I have +1 on the trunk patch, I'll prep the
equivalent branch-1-win patch.

> In general, the winutils symlink command rejects attempts to create symlinks
> targeting a destination file that does not exist. However, if given a
> symlink destination with forward slashes pointing at a file that does exist,
> then it creates the symlink with the forward slashes, and then attempts to
> open the file through the symlink will fail.
