Bug 48494 – fix setSize() order in WebP image decoding

• Component: Images
• Status: RESOLVED FIXED

[Pascal Massimino]

Hi,

in WEBPImageDecoder.cpp, setSize() was only called
when onlySize was true, causing refresh problems.
This patch makes sure setSize() is always called
appropriately.

Looks good, but we need a ChangeLog and (ideally) a test.

If any of these errors are false positives, please file a bug against check-webkit-style.

You need to fill out all those fields in the ChangeLog (except the Reviewed by NOBODY line).  Also, we can't land a patch with tabs.

Adam,

oops... added the missing ChangeLog...

to exercise the bug (lack of refresh) there's some manual intervention required:
 - load a big picture
 - switch to another tab
 - switch back to the picture tab
 - scroll up/down
=> some parts were blank.

I'm not sure how a test can reproduce that...

This line is ok because the tools fill in the reviewer automatically for you.

> WebCore/ChangeLog:6
> +        fix setSize() call flow: it was only called the first
> +        time (when onlySize is true)

Also, you should link to the bug from the ChangeLog so folks can find it from the SVN revision history.

> WebCore/ChangeLog:8
> +        No new tests. (OOPS!)

There's an SVN pre-commit hook that rejects OOPS in files.  This line will prevent the patch from being landed.  You should replace this line with an explanation of why there is no test.

fix the changeLog: add bug URL, explain the missing test.
