Bug 62813 – [filesystem] Remove old filesystem naming restrictions

• Status: RESOLVED
• Resolution: FIXED
• Component: DOM

[Eric U.]

The FileSystem spec has changed, and in particular has removed a lot of restrictions on how one can name files and directories [see http://dev.w3.org/2009/dap/file-system/file-dir-sys.html].  We should remove the restrictions from DOMFilePath::isValidPath.

Before this change goes in, however, Chromium will have to fix http://code.google.com/p/chromium/issues/detail?id=78860 [via https://bugs.webkit.org/show_bug.cgi?id=62811] or it will suddenly get much, much worse.

The chromium bug isn't fixed yet, but it's close, so I think we can go ahead and fix this one now, given that the code I'm removing has threading issues.

Who would be famliar enough with the spec to review this?  (even a non-reviewer)

This statement is false. :)

Kinuko [on the CC list] knows it well.  I believe David Levin's going to look at it, though, since this CL removes some non-thread-safe code that's annoying him.

Well, modifications of existing tests, I suppose.  OOPS! indeed.  ;'>

Just remove it and put in the correct statement.

NUL? Embedbed \0 are not allowed.

> +    if (path.find((UChar)0) != WTF::notFound)

Use c++ style casts. Or why not just do '\0'?
