514005 - Table layout reftests involving border-collapse fail on WinCE tegra device

Status: RESOLVED WONTFIX

(Core :: Layout: Tables, defect)

Description

[Jonathan Griffin (:jgriffin)]

Attachment: reftest log

A group of 15 table layout reftests involving the CSS border-collapse property fail on the Windows CE tegra device.  The tests pass on desktop Firefox.

The REFTEST IMAGE data which is normally available for failed reftests, for use in the reftest analyzer, is not available for tests run on the tegra device.

The failing tests are:

layout/reftests/table-background/border-separate-table-column.html
layout/reftests/table-background/border-separate-table-row-group.html

Attachment: reftest log with image data!

New reftest log which includes reftest analyzer image data.  This log was saved from a run on the following build of the tegra:

Mozilla/5.0 (Windows; U; WindowsCE 6.0; en-US; rv:1.9.2a2pre) Gecko/20090902 Namoroka/3.6a2pre

[Vladimir Vukicevic [:vlad] [:vladv] (needinfo me, slow to respond)]

This looks like a 16bpp dithering issue more than anything else; the images look identical to me, especially with regards to borders.  We should probably avoid using anything with may discrete colors (like that rainbow image) in tests, or we'll always have dithering issues with this stuff... unless we're explicitly checking that.

Comment 3

[Bernd]

There are no visible borders in those test cases, the last test cases move all images up regardless of their rainbow color.

Comment 4

[Ed Morley [:emorley]]

WinCE/Windows Mobile support has been removed from the main build system, Spidermonkey, mobile installer, in-app updater and so on (see bug 614720, bug 554087 and all their dependants). Until such point where MS decide to release a Windows Phone 7 NDK and the decision is made to port to that platform, this is WONTFIX.
