Make audit_path more stringent. The following properties of a path are now checked for: - under top-level .hg - starts at the root of a windows drive - contains ".." - traverses a symlink (e.g. a/symlink_here/b) - inside a nested repository If any of these is true, the path is rejected. The check for traversing a symlink is arguably stricter than necessary; perhaps we should be checking for symlinks that point outside the repository.
