David Storey - Squashing bugs on the road to Kestrel

Squashing bugs on the road to Kestrel

Monday, 26. February 2007, 15:59:58

As the build numbers roll on in the development of our next major release, there is some good news on the long standing bug front. When talking about standards support in Opera, many people bring up the example here of a bug Opera has had since version 7. This test page shows that Opera has a bug where when margin or padding has a value of over 20.47ems, Opera has a rounding issue that rounds all decimal places above that to the next whole number. The great news for all web designers and people that like to bring up this bug, is that in the latest builds of Kestrel this is now fixed. A screenshot of this in action can be found here.

Thanks to Tim Altman for pointing out this bug fix on his blog.

Now this is fixed what other bugs cause you the biggest pain when trying to get your sites working in Opera? I'd like to push to get the issues that cause the greatest problems fixed as soon as possible.

How about use rounding instead flooring?
Opera, Safari and iCab use flooring.
Internet Explorer, Mozilla use rounding.
Firefox 3 Alpha does best job for now.
Why not follow "big brothers" in that case?

Other pains for me as web designer:

Strange padding (introduced in Opera 9)
Inaccessible links (introduced in Opera 9) bug # 227187 - WordPress default template also being hurt...
Unnecessary horizontal scrollbar showed for the whole page, but only when float used... (Opera 7, 8, 9)

What about bugs listed on my page: http://bugs.blaut.biz/ ? Especially long standing: http://my.opera.com/community/forums/topic.dml?id=30837

...And if you have time to fix more, please look at broken generated content (introduced in Opera 9)

FataL: do you have bug numbers for those, or have they not been reported?

Andrey Petrov # 26. February 2007, 21:35

I will try to find bug numbers and post them here.

Quiris: If the second issue is bug 126535 then it is fixed.

WOW! Incredible

Thank you! What about other 15 bugs?

Please talk a look at this farm:
http://zajec.net/bugi

Especially:
scrolling.textarea
gmail_jumping
Flickering_Favicon (actually wrong pointer now)
and probably same as the last one - link_cursor

Have a good read

And the most important - positioned blocks inside inline elements. Will this work without redraw issues?

David Storey # 28. February 2007, 03:26

Fatal: Bug 227187 is marked as a duplicate, and the bug that it is a dup of is fixed so I assume it works now.

d.i.z: you have a bug number or testcase for the last issue you hi-light?

Robert Błaut # 28. February 2007, 06:05

bug-254066

bug-254066

Well, this is not exactly the case I was talking about.
There is no block inside inline in this testcase (although this testcase was originally like this).
I will try to look for this particular bug when I get home tonight.

Quiris: bug 254066 is fixed

My most annoying bug is where Opera sometimes does weird things when given large negative lengths in CSS. The threshold seems to be around -32767px (or equivalent in other units, -9999em qualifies). I've reported bug 246155 for this, although that bug only mentions missing scrollbars. I've seen missing or misplaced content too.
