Sebb commented on IO-299:
-------------------------
The Javadoc says clearly that Unix and Windows are treated the same, also that
invalid names return null.
Although double-slashes are collapsed to a single slash, this does not apply at
the start of a path, because there they are used for UNC names in Windows.
As far as I can tell, the current behaviour is correct, because UNC paths must
have a valid server name.
The Javadoc should probably be updated to clarify this; it would help to add
some examples (and test cases if necessary).
> getPrefixLength returns null if filename has leading slashes
> ------------------------------------------------------------
>
> Key: IO-299
> URL: https://issues.apache.org/jira/browse/IO-299
> Project: Commons IO
> Issue Type: Bug
> Components: Utilities
> Affects Versions: 2.0.1, 2.1
> Reporter: Rick Latrine
> Original Estimate: 2h
> Remaining Estimate: 2h
>
> Situation:
> FilenameUtils.getPrefixLength is used in FilenameUtils.doNormalize.
> FilenameUtils.normalize("////I don't want to become null!") returns null.
> Problem:
> Expected was: "I don't want to become null!"
> The method FilenameUtils.getPrefixLength returns -1 for the mentioned string.
> The root problem is found in following lines of code:
> {code:title=FilenameUtils.getPrefixLength}
> ...
> int posUnix = filename.indexOf(UNIX_SEPARATOR, 2);
> int posWin = filename.indexOf(WINDOWS_SEPARATOR, 2);
> if ((posUnix == -1 && posWin == -1) || posUnix == 2 || posWin
> == 2) {
> return -1;
> }
> ...
> {code}
> Solution:
> All leading slashes should be ignored at all, but considering the rest of the
> string.
