[jira] Commented: (MSHARED-121) FilteringUtils.escapeWindowsPath doesn't handle paths that leave out the drive letter.

Kathy Hale commented on MSHARED-121:
------------------------------------

It's funny you say that because I have the opposite problem. I'm using this bug to disable the auto trigger because I couldn't find any way to disable it. So if I need a path to remain unescaped (single backslashes, not doubled), I've been breaking up the filter param like "${drive}${path}", such that ${drive} is "{{C:}}" and {{${path}}} is "{{\path\}}."

> FilteringUtils.escapeWindowsPath requires a drive letter to be present in the path, or at least the string {noformat}":\\"{noformat} to be present in order to trigger escaping the value as a windows path.
> In cases where the path is an absolute reference to a file on the current drive (no drive letter is included), or when the path starts with an unresolved expression (in cases where n+1 level interpolation will eventually resolve the expression), escaping doesn't happen at all.
