Subject [jira] [Commented] (IVY-1498) Mixed use of symlinks leads to cache corruption

Stephen Haberman commented on IVY-1498:
---------------------------------------

Hi [~hibou], sorry about that, I'd probably rebased it at some point; here's my "symlink_fix"
branch:

https://github.com/stephenh/ant-ivy/commits/symlink_fix

Only the 1st "Avoid corrupting ivycache by writing to symlinks." is required. The 2nd was
a cleanup that assumed Java 7.

Sorry I don't have any tests for this one.

> If a user switches between "use symlinks" or not (or, say, has ant/ivy configured with
symlinks but Eclipse/IvyDE without symlinks), the ivycache can be corrupted.
> Specifically, if a symlink was setup in symlink mode:
> lib/foo.jar --> ivycache/com/foo/foo-1.2.jar
> And then later we retrieve into lib without symlink mode, Ivy retrieve will write, say,
foo-1.3.jar's bytes into the lib/foo.jar location...which will then overwrite the foo-1.2.jar
bytes in the ivycache.
