*sadfaces* CPG has broken e4x for the gdata provider, so I need to solve things differently for the Lightning 1.7 release.

This removes e4x usage. I hope I didn't miss anything and that everything works!

Phillip, can this be applied to versions of Provider running under earlier Lightning releases, or will I need to wait to test until I have a working Lightning 1.7 build?

The patch will work with earlier releases too, as the techniques used are standard DOM and XPath, but its only broken in Lightning 1.7 and the matching Thunderbird where the CPG patch has landed.

Thanks, Philipp (apologies for the typo last time!). I'll patch my current installation to see if anything odd happens. I don't do the Lightning builds for OS/2, so I'm not sure when Dave will be putting a 1.7 together. It's good to know that this shouldn't break backward compatibility.

Don't worry, 1.7 is at least 12 weeks down the road :-)

Well, we weren't so lucky insofar as backward compatibility is concerned. I noticed it in the diff, but didn't look much further.

The diff references:


which doesn't exist under Lightning 1.2.3 (at least, not on my system).

So, upon applying the diff and restarting, I get:

Tue May 22 2012 22:28:35
Error: [Exception... "Component returned failure code: 0x80520012 (NS_ERROR_FILE_NOT_FOUND) [nsIXPCComponents_Utils.import]"  nsresult: "0x80520012 (NS_ERROR_FILE_NOT_FOUND)"  location: "JS frame :: resource://calendar/modules/calUtils.jsm -> file:///J:/OS2WEB/Mozilla/SeaMonkey/Profiles/4h0tldty.default/extensions/%7Ba62ef8ec-5fdc-40c2-873c-223b8a6925cc%7D/js/calGoogleUtils.js :: <TOP_LEVEL> :: line 40"  data: no] (file:///J:/OS2WEB/Mozilla/SeaMonkey/Profiles/4h0tldty.default/extensions/%7Ba62ef8ec-5fdc-40c2-873c-223b8a6925cc%7D/js/calGoogleUtils.js)
Source file: resource://calendar/modules/calUtils.jsm
Line: 86

And it's not just an easy matter of pulling calXMLUtils.jsm and/or the updated calUtils.jsm from cvs and dropping them in the Lightning /modules directory, either.

So, it looks like this isn't as backward-compatible as I'd hoped, but no matter. I'll wait until I'm in a better position to test. ;-)

Oh right, forgot that one. You can get the file here:

and then just drop it into this path:

Isn't that odd... I did that before (see my comment 6), but I still got an error in the console (referencing a missing ";" in calUtils.jsm, but running the patch again this time and restarting (with the calXLMUtils.jsm in place), it all worked. I guess my initial patch must have not quite gone through.

Anyway, it's up and running now, so I'll play wiht it for a couple of days and will let you know if I find anything which is not working right.
