• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Pavel Podivilov]

Web Inspector: do not re-create RawSourceCode when toggling pretty-print mode.

* implement RawSourceCode.setFormatted that allows toggling pretty-print mode on the fly without recreating everything
* add RawSourceCode unit tests
* remove source mapping listeners and console messages from presentation model

Can this test be split into a few smaller ones?

It should be originalSetTimeout.call(window,...)

Why do you do it exactly thrice? Should it loop until timers is empty? If you assume that firing timers may modify "timers" map it should be cloned before the iteration.

Here and below script content and start/end line/column should be in sync, otherwise the test uses invalid scripts. r- for this.

Can this method derive end coordinates from the start and source?

This is a set of unit tests for a single class, I think it's nice to have them defined in the same file. Also, it's faster than loading multiple test documents.

Done.

I don't want this test to start timing out if there is a setTimeout chain somewhere.
Three times is just enough for the test purpose, and there shouldn't be any problems with it.
Keys list is cloned by VM, no need to do it manually (items added during enumeration are guaranteed not to be visited.

Are there real setTimeout chains that can't be handled with listeners/sniffers like in other inspector tests? We don't intervene in the timer in other tests I don't see why we should here.

Good to know.

Removed use of timers from RawSourceCode._createSourceMapping and the test.

I think it's fixed in http://trac.webkit.org/changeset/94689.

Mn... the test still appears to be flaky on Qt:

I'm going to rollout the patch for now since I don't understand what the test is testing or what this change is about, and nobody appears to be actively working on it.
