Bug 53943 – VisibleSelection::setWithoutValidation() should allow caret selection.

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Jia Pu]

Currently setWithoutValidation() fails on "ASSERT(base != extent);" when undoing some paste operation. It also cause assertion failure in the patch for bug 52221. This function should be modified to allow caret selection.

How do we test this?  Please add tests or explain why testing is imposible in the ChangeLog.

Jia, can you create a test that exercises the case where you are undoing a paste operation that you mentioned in your description?

I have added such test.

Also, comparing the test result on LayoutTests/fast and LayoutTest/editing, this patch doesn't introduce any new test failure.

Darin, did I miss something in the ChangeLog, or is it something you need to do?

You removed the Reviewed by NOBODY (OOPS) line from the change logs or wrote them yourself so those lines are not in there. That is not right, because those lines are edited by the script to put in the reviewer name. You should post a new patch with those lines added back in.

Hmm, I'm almost certain I have received conflicting information from someone else. In fact, I did this to all the patches I have submitted. Somehow they all got landed. 

Anyway, I have uploaded a new patch. Thanks.

Maybe you’re confusing the “no tests” OOPS with the “reviewed by” OOPS?

Maybe you can point me to an example if you’d like to unravel the mystery.

Ah, my mistake. There're only a couple of patches without "OOPS" line. They seem to have been landed manually.

New problem is this:

undo-paste-when-caret-is-not-in-range.html is failing on WebKit2.  I can't tell whether or not a missing DRT feature is causing the failure: http://build.webkit.org/results/SnowLeopard%20Intel%20Release%20(WebKit2%20Tests)/r77995%20(8289)/editing/undo/undo-paste-when-caret-is-not-in-range-pretty-diff.html

It's also failing on GTK, Qt, and Windows:

hmm, does this mean I should generate platform specific expected file? how should I go about this if I don't easily have other platforms readily available.

Or can the test be written in a more platform independent way?

[Jia Pu]

I guess I should have used "layoutTestController.dumpAsText". Will upload a patch tonight.

OK.

[Jia Pu]

Reopened to submit additional patch.

[Brian Weinstein]

This test has been failing on Windows since it landed, added Windows-specific failing results in r78082.

If you could investigate and figure out the issue that is causing this test to fail on Windows, that would be great.

https://bugs.webkit.org/show_bug.cgi?id=54120 tracks the failure.

[Jia Pu]

The reason for test failure on other platforms is that I was dumping the render tree instead of plain text, hence the different result on different platforms. 

I have submitted a second patch to fix the test. Darin r+'ed it. But I forgot to change the bug status back to "REOPENED", so the build bot refused to process the patch. Can someone re-approve it and commit+ it? Thanks

I think a separate bug reports works best in cases like this.

[Darin Adler]

We’ll see if changing the flags like this works or not.
