Bug 97171 – Support the replace attribute of window.open

• Status: RESOLVED
• Resolution: WONTFIX
• Component: WebCore JavaScript

[KyungTae Kim]

According to a spec of window.open() below, if the 'replace' attribute is false, the current window must be exist in the window's session history.
http://www.w3.org/TR/2009/WD-html5-20090423/browsers.html#dom-open

When test with the attached html file, 
I can back to the page after redirected on the IE and the the Firefox, but not on the Webkit browser.

Is the last parameter of the below function ignored on Webkit?
window.open("http://www.google.com", "_self", "", false);

The standard says  "the replace attribute, if true, means that whatever page is currently open in that window will be removed from the window's session history".
http://www.w3.org/TR/2009/WD-html5-20090423/browsers.html#dom-open

Then, if the replace attribute is false, what is proper operation?
Not remove the current opened page, or following "by the user gesture" rules?

Looks like you have compile and test failures.

> Source/WebCore/page/DOMWindow.cpp:1933
> +        bool lockHistory = false, lockBackForwardList = false;
> +        if (locking == LockHistoryAndBackForwardList)
> +            lockHistory = lockBackForwardList = true;

This is pretty far out of style.  Please take a look at http://www.webkit.org/coding/coding-style.html

First, that's a REALLY OLD version of the spec, quite obsolete. The up to date link is:

   http://whatwg.org/html#dom-open

The behaviour of the "replace" argument is just "If the replace is true or if the browsing context was just created as part of the rules for choosing a browsing context given a browsing context name, then replacement must be enabled". (The text quoted in comment 6 isn't normative and doesn't define what "replace" does, it's just descriptive. Please ignore it for when implementing the spec. See the introduction to the spec for information on how to read the spec to avoid interpreting non-normative statements as normative ones; the basic idea is that if it doesn't say "must", it's not normative.)

The meaning of "replacement enabled" is defined here:

   http://whatwg.org/html#replacement-enabled

If "replace" isn't specified, then replacement isn't enabled and so the text above doesn't take effect.

HTH.

Only IE/Edge implements this. It looks like it is about to get removed from the specification:
