| <p> Test case for <a href="https://bugs.webkit.org/show_bug.cgi?id=36156"> bug 36156</a>: XHR 'progress' event code assumes wrongly that expectedLength >= 0</p> |
| <p> Verify that the progress event total property is 0 when the expected overall length can't be computed.<p> |
| <p>PASS should appear below:</p> |
| <p id=console></p> |
| <script type="text/javascript"> |
| if (window.testRunner) { |
| testRunner.dumpAsText(); |
| testRunner.waitUntilDone(); |
| } |
| |
| function log(message) |
| { |
| document.getElementById('console').appendChild(document.createTextNode(message + '\n')); |
| } |
| |
| function test() |
| { |
| var xhr = new XMLHttpRequest(); |
| xhr.open("GET", "resources/chunked-transfer.php", true); |
| |
| xhr.onprogress = function(e) { |
| if (xhr.readyState != xhr.LOADING) { |
| // As this test ends when a readystatechange event arrives with |
| // readyState == DONE, a "progress" event cannot arrive when |
| // readyState == DONE. |
| log("FAIL: xhr.readyState must be LOADING when a progress event arrives, but is " + xhr.readyState); |
| } |
| if (e.loaded == 4 && e.total == 0 && !e.lengthComputable) |
| log("PASS"); |
| else if (e.total != 0 && !e.lengthComputable) |

| xhr.onreadystatechange = function(e) { |
| if (xhr.readyState == xhr.DONE) |
| { |
