Subject: Re: [webkit-changes] [24935] trunk

Hi Kevin,

 You are right that HTML 5 only specifies the behavior of createElement for
HTML documents (which is not directly related to HTML serialization though).
However, the concept of "a Document created with an XHTML MIME type" is
completely alien to this spec AFAIK, so our current behavior is in rather
bad contradiction with it.

 Also, Hixie's comments in bug 8007 and other ones seem to indicate that
the intention is to make namespace-unaware methods behave consistently in
XML and HTML documents as much as possible.

 Looking at Zimbra's bugzilla, I believe that yes, their TOT works with
Safari 3 (pre-r24935). I haven't tested this myself, though.

Hi Alexey, hopefully I am explaining this correctly.  r24935 was aimed

at changing crateElement wrt XML serialization (as opposed to HTML

serialization) which I don't believe is specified in the HTML5 spec,

and the change is purely to match compatibility with FireFox (the

differences I saw I turned into the layouttests).  Are you sure Zimbra

workes with TOT before r24935?

If I'm unclear on something please feel free to clarify

any workarounds. Do we have any other reasons to be non-conformant

HTML5? If not, I'd suggest reverting r24935.

Hi Kevin,

Thank you for the clarification!

Do you expect that this will make it to HTML5, or will WebKit be

non-conformant from the very beginning? HTML5 seems to have a nice

model

(old-style DOM functions always work in HTML namespace), and doesn't

have a

notion of "a Document created with an XHTML MIME type" AFAICT. A

real life

site that breaks on an "isSafari" branch is not a very convincing

example.

Hi Alexey,

  Sorry I wasn't clearer.  I reverted r24146 and added some code

so

now you will get an XHTML namespace when calling CreateElement if

you

are an HTMLDocument or a Document created with an XHTML MIME type.

I will update the bugs below with this information.  I think 14835

can

probably be closed, and the rest just need a comment.  This does

fix

the given error in 11565 but we are still unable to log into Zimbra

for another reason.

I think 8007 is where the conversation for this issue should take

place.  I'll add a comment.

What is the new behavior, and is it documented anywhere? It's not

even

quite obvious which previous change was reverted.

See bugs 8007, 14506, 10932, 14835 - I think some or all of them

may need

to be updated to describe the new behavior.

Would it be possible to have this bug reflected in Bugzilla, so

that the

rationale would be known? It's good to know the title of the bug,

but maybe

there was some useful information in the report and in subsequent

discussions?

In particular, I'm wondering if this is in fact a workaround for

some

broken Safari-specific code in Zimbra (see bug 11565, which is

probably

different, but may be tangentially related).
