Comment 3 Santosh Mahto 2013-10-14 06:38:46 PDT 
There is two bug in the crash.

1. Actual assert is probably useless. on remove-format command we need to remove the property even if it is declared as !important.

2. second pushing down style on iframe element. it is done in same way as for other inline element. adding styled node around inline element.But this triggers looping in onload event call, as new node are inserted in iframe which again triggers loadframe and again onload eventhandler are called.

So pushing down style on iframe element should be done by adding style attribute to iframe element.

I uploaded the patch which solves the crash,
Please review....

This doesn't make any sense. The whole point of setTextDecorationProperty is to take care of that.
We should figure out why setTextDecorationProperty has the assertion instead of working around it here.

Please fix the indentation.
Also, we should use dump-as-text or dump-as-markup.
There is no reason for this test to be a render tree dump.
r- because of this.

Another testcase(bit less confusing)

Bit simple test case .

Try as it is OR   remove contenteditable from <html contenteditable> and uncomment designmode.
Both case it will crash in setTextDecorationproperty.
Comment 6 Santosh Mahto 2013-10-16 10:34:59 PDT 
New test case code.

<!DOCTYPE html>
<html contenteditable>

    <body  style="text-decoration: underline !important;"><p>dasda</p>foo
    <span >santosh</span>
	<script>
   // document.designMode='on';
	document.execCommand('selectall');
	document.execCommand('RemoveFormat', false, null);

> Why?

Yes becasue we do it for other styleproperty in same function. In code ApplyStyleCommand::addInlineStyleIfNeeded :  we try to find StyleChange that we need to apply(pushing down style in conflicting style node childs).
 StyleChange class constructor doesnot consider !important in its calculation for any other property.it just try to find 6 text changes to applied.
    : m_applyBold(false)
    , m_applyItalic(false)
    , m_applyUnderline(false)
    , m_applyLineThrough(false)
    , m_applySubscript(false)
    , m_applySuperscript(false)

What I mean is these text properties are applied in different way (by surrounding with node <b>, <i> etc) not by CSS rules to child node. So we need to clear out css style (style->removeProperty()) whether it is declared !important or not.

!important property is used in resolving the style among multiple CSS contenders. since for textdecoration:underline !important  we will enforce style by adding node(utag) so !important consideration is useless.

As above explanation: since textdecoration:underline style will be applied by surrounding node and so !important is not relevant. So We should remove property[ style->removeProperty(propertyID);](if empty) even if it is declared as important in code.

So in this path of flow ASSERT is wrong.
I think better way is to remove ASSERT from setTextDecorationProperty.

I will update updated testcase in next patch, thanks

There is more to explain: 
Actually crash is Quite general(see next test case).

code modification in iframe:
As you can see in patch I added an iframe check. The reason for this was that
since we apply style on inline block by surrounding with node(utag, <b>), To do this we disconnect iframe node and again reattach as child of styling node.But whenever iframe node is added on tree, subframe loading is triggered and again onload event handler will be called (1st test case) and again everything will repeat and finally stackoverflow.

But I think node->renderer()->isReplaced() will be a better check there.

please comment if i confused you anywhere...

All replaced elements?  So we do this for img, input, etc...?  That doesn't sound right.
We also need tests for that.

I think the point of this code is that if text-decoration was specified with !important then we don't want to be overriding it with a new text decoration.
We should add a bunch of test cases for that.

Can we move this function out of the attribute and put it in the script element below?

You are probably right.., considering the domain of bug it not right to change the behavior for all replaced element. I am planning to stick to just iframe check.

The point is new text decoration at this point will  be empty.
     if (newTextDecoration->length())
{
}
    else {
        ASSERT(!style->propertyIsImportant(propertyID));
        style->removeProperty(propertyID);

The point is new text decoration at this point will  be empty. So we remove the property. it does not matter its important or not. 

     if (newTextDecoration->length()) 
    {
    }
    else {  // newTextDecoration->length() == 0

        ASSERT(!style->propertyIsImportant(propertyID));  
        style->removeProperty(propertyID);
    }

  But here we should always override as per current flow.
Here we are not allowing removing of text property if it is declared !important.this way we would be end applying text decoration in two way simultaneously(one by style property and other by utag)

Regarding removal of ASSERT in setTextDecorationProperty():

setTextDecorationProperty() is private function and called from two places in EditingStyle Class. I checked the both scenarios and found ASSERT is wrong in setTextDecorationProperty(). There is no meaning of !important if new text decoration value is empty in Editing scope.

Are you use neither function is called while pushing style in ApplyStyleCommand?  The problem here is that even if new text-decoration was empty or some other value, we shouldn't be overriding a property with !important.

Although we don't do a good job dealing with !important anyway so there is an argument to be made about ignoring !important in some cases.

Regardless, we need a lot more test cases involing !important in applying & removing inline styles.

I got your concerns. The !important  handling is really debatable here.
Although changes look ok to me (with overriding issue). But really I need to write more test cases covering the inline style handling scenario and to confirm about safety.

Thanks for your points...

On my second thought, it might make more sense to simply ignore iframe because adding inline style on iframe should have no effect.
e.g. underlining, bolding, etc… iframe doesn't make any sense since the said inline style won't be applied to the content inside iframe.

Although if iframe's fallback content were to be shown, perhaps…

Nit: Space around =.

> +    document.execCommand('selectall');

Why don't we also capitalize SelectAll?

> LayoutTests/editing/execCommand/remove-format-textdecoration-in-iframe.html:15
> +    Markup.dump('container');

Since the style is on body, it doesn't really help to dump the body. Can we add a wrapping node inside body with text-decoration?
If that doesn't work, it might make sense to dump the whole html after removing script elements (to avoid cluttering).
