           Summary: XMLHTTPRequestUpload events not firing
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh Intel
        OS/Version: Mac OS X 10.6
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: XML
        AssignedTo: webkit-unassigned at lists.webkit.org

Webkit does not seem to fire various events (onload, onprogress) when uploading
files with XMLHTTPRequest.send. I found bug
https://bugs.webkit.org/show_bug.cgi?id=26979 and used FormData to send the
files (I added Firefox's get/sendAsBinary way to test FF, see:
https://developer.mozilla.org/en/Using_files_from_web_applications and
http://blog.igstan.ro/2009/01/pure-javascript-file-upload.html, hopefully FF
soon lands FormData too, so it automatically handles headers).

The test I used: http://pastie.org/925509, server side:
http://pastie.org/925510. (I tested with "real server" with my home connection,
uploading a pdf file about 700KB.)

Output with webkit (nighlty, r57720):
(0) request readystatechange: 1
(0) request start
(0) upload start
(0) request readystatechange: 2
(0) request progress: 60 / 60 = 100%
(0) request readystatechange: 3
(0) request readystatechange: 4
(0) request finished: upload success fileinput : file.pdf

The inspector shows 2.4s for the XHR.

The same test with Firefox (v3.6.3):
