XSLTProcessor fails with <import>

Add-ons Development
#1

I’ve been using XSLTProcessor without problems like this:

  var xsltProcessor = Cc['@mozilla.org/document-transformer;1?type=xslt'].createInstance(Ci.nsIXSLTProcessor);
  xsltProcessor.importStylesheet(xsl);
  var result = xsltProcessor.transformToFragment(xml, doc);

Starting with 45a builds importing another xsl file fails:

<xsl:stylesheet version="1.0"
                xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:import href="file.xsl"/>
    ...
</xsl:stylesheet>

This code is called from a XBL binding. importStylesheet() throws an exception without message or name:

Exception { message: “”, result: 2153775131, name: “”, filename: “file.js”, lineNumber: 46, columnNumber: 0, data: null, stack: “…”, location: XPCWrappedNative_NoHelper }

I’ve had a look at recent changes, but that didn’t really help to find a solution. Also, I can’t look at the associated bug report (“You are not authorized to access bug 1072150”). Release notes for developers don’t mention anything related to this as far as I can see. I’m stumped. What can I do about this?

I suggest that you file a new bug for that regression, make it block bug 1072150 and needinfo the patch author (Bobby Holley) about it. It could be that it’s a necessary security fix, or it could be an unintended consequence.

#3

Thanks, just added the bug, but I’m not allowed to make it block the other bug or even just reference it either.

#4

What’s the number of the bug you filed?

#5

It’s bug 1249572.
