After this revision the tst_qwebhistory stuck with this output: ********* Start testing of tst_QWebHistory ********* Config: Using QTest library 4.6.2, Qt 4.6.2 PASS : tst_QWebHistory::initTestCase() PASS : tst_QWebHistory::title() PASS : tst_QWebHistory::count() 239031 1 fishd 2010-06-16 13:00:00 -0700 Perhaps this is related to the addition of the HistoryItem::itemSequenceNumber property. http://trac.webkit.org/changeset/61207 I don't know enough about the Qt port, but if you have any questions about that patch, I'd more than happy to help answer them. 239305 2 jedrzej.nowacki 2010-06-17 02:17:15 -0700 I reprodced it, It is not an infite loop it simply hangs. I don't think that it is related to HistoryItem::itemSequenceNumber. It seems that QWebPage doesn't emit signal loadFinished() after call to QWebHistory::back(). 239325 3 ossy 2010-06-17 03:47:40 -0700 FYI: I disabled running tst_qwebhistory test on http://webkit.sed.hu/buildbot/waterfall site temporarily (until fix) to make bot happier. 239350 4 jedrzej.nowacki 2010-06-17 05:48:02 -0700 (In reply to comment #2) > I don't think that it is related to HistoryItem::itemSequenceNumber.

Now loadFinished signal can be emitted immediately. I think that it should be ok, as we didn't explicitly define it. 240437 6 59103 hausmann 2010-06-20 04:30:31 -0700 Comment on attachment 59103 Fix v1 WebKit/qt/tests/qwebhistory/tst_qwebhistory.cpp:87 + connect(page, SIGNAL(loadFinished(bool)), &waitForLoadFinished, SLOT(quit()), Qt::QueuedConnection); Why the queued connection? 240438 7 59103 commit-queue 2010-06-20 04:46:29 -0700 Comment on attachment 59103 Fix v1 Clearing flags on attachment: 59103 Committed r61504: <http://trac.webkit.org/changeset/61504> 240439 8 commit-queue 2010-06-20 04:46:34 -0700 All reviewed patches have been landed.

As I wrote in comment 5 the patch slightly change behavior. I think it is because load function isn't called while traversing through history. 242512 10 ossy 2010-06-24 07:45:30 -0700 It works with Qt-4.7: ********* Start testing of tst_QWebHistory ********* Config: Using QTest library 4.7.0, Qt 4.7.0 PASS : tst_QWebHistory::initTestCase() PASS : tst_QWebHistory::title() PASS : tst_QWebHistory::count() PASS : tst_QWebHistory::back() PASS : tst_QWebHistory::forward() PASS : tst_QWebHistory::itemAt() PASS : tst_QWebHistory::goToItem() PASS : tst_QWebHistory::items() PASS : tst_QWebHistory::serialize_1() PASS : tst_QWebHistory::serialize_2() PASS : tst_QWebHistory::serialize_3() PASS : tst_QWebHistory::saveAndRestore_crash_1() PASS : tst_QWebHistory::saveAndRestore_crash_2() PASS : tst_QWebHistory::saveAndRestore_crash_3() PASS : tst_QWebHistory::popPushState() PASS : tst_QWebHistory::clear() PASS : tst_QWebHistory::cleanupTestCase() Totals: 17 passed, 0 failed, 0 skipped ********* Finished testing of tst_QWebHistory ********* But unfortunately it still hangs with Qt 4.6.2: ********* Start testing of tst_QWebHistory ********* Config: Using QTest library 4.6.2, Qt 4.6.2 PASS : tst_QWebHistory::initTestCase() PASS : tst_QWebHistory::title() PASS : tst_QWebHistory::count() PASS : tst_QWebHistory::back() PASS : tst_QWebHistory::forward() PASS : tst_QWebHistory::itemAt() PASS : tst_QWebHistory::goToItem() PASS : tst_QWebHistory::items() PASS : tst_QWebHistory::serialize_1() ^CQFATAL : tst_QWebHistory::serialize_2() Received signal 2 --> I stopped here. 244261 11 jedrzej.nowacki 2010-06-29 06:45:21 -0700 (In reply to comment #10) > It works with Qt-4.7: (...) > But unfortunately it still hangs with Qt 4.6.2: I can confirm, it doesn't work with 4.6.2, but I tried 4.6.3 (default on my debian machine) and it is ok. 244281 12 jedrzej.nowacki 2010-06-29 07:26:00 -0700 It is really odd, It seems that there are a dependency between tests even if an operation are applied to different instances of the QWebPage.

I couldn't find a Qt change that was neccessery for the workaround as the only link to it was via an expired pasbin's element. 245202 14 60212 jedrzej.nowacki 2010-07-01 01:35:07 -0700 Comment on
