As described in bug 644596, we have to implement the rest of the de-facto standard methods in the console object. This bug will track the work for the group, groupCollapsed and groupEnd methods.

A simple implementation for group/groupEnd that does not allow collapsing the grouped messages.

The simplest implementation possible. Proper group labels are displayed, new messages are indented as expected, but you can't collapse the groups, like you can in Firebug and WebKit Inspector. Group collapsing will be implemented in a followup bug. Here is a screencast showing this in action: http://vimeo.com/25082943

The behavior is identical to what webkit and firebug do: when too many nested groups have been started, the console output grows larger and we get a horizontal scrollbar. > ::: > toolkit/components/console/hudservice/tests/browser/ > browser_webconsole_bug_664131_console_group.js > @@ +24,5 @@ > > + content.console.group("a"); > > + findLogEntry("a"); > > + let msg = outputNode.querySelectorAll(".webconsole-msg-icon-container"); > > + is(msg.length, 1, "one message node displayed"); > > + is(msg[0].style.margin, "0pt 0pt 0pt " + GROUP_INDENT + "px", "correct group indent found"); > > Please only check style.marginLeft. Done. Thanks for the review!

Rebased against latest fx-team repo.

Rebased due to the creation of the new devtools module. This patch has already received an r+ from Mihai who is a devtools module peer, so Gavin, I think you only need to look at the dom/ bits, and perhaps more importantly, with your sr hat on.

That doesn't > seem desirable. You are absolutely right! This version stores the current depth in the HeadsUpDisplay object which is unique per tab. I also rebased the patch on top of the latest fx-team.

Just a note for future reference - it would be ideal to generate patches with at least 8 lines of context. This patch in particular is rather sucky to review with the default 3 lines :) https://developer.mozilla.org/en/Installing_Mercurial#Configuration has some config examples.

Comment on attachment 550706 [details] [diff] [review] Patch v6 I don't think this is suitable either, since a HUD object is still shared amongst a top-level window and all of its child frames, so frames from different contexts can still interfere with each other. I think you'll need a solution similar to the one for bug 658368 (perhaps code can even be shared for storing per-window state like this).

Sorry about that, I'm using 3 lines of context (per jorendorff's suggestion) to reduce the merge conflicts with mq. I was just being lazy and uploaded the mq patch file as-is, instead of using hg diff to get 8 lines of context. This is the relevant part of my configuration: [defaults] commit = -v diff=-U 8 -p qdiff=-U 8 qnew = -U [diff] git = 1 showfunc = 1

Panos, I suggested in bug 669658 that we do a manual qdiff -U 8 (looks like you've already got that set, goody!) for producing patches for review.

I think you'll need > a solution similar to the one for bug 658368 (perhaps code can even be > shared for storing per-window state like this). Let me see if I understand the failure scenario. Pointing two different tabs at http://htmlpad.org/group with consoles opened does not seem to cause interference in the grouping, after the fix in v6. That is, if you only click the outer button. On the other hand, clicking on the button in the iframe causes the log message grouping in the iframe to be dependent on the grouping level of the outer frame. This however is consistent with what the other browsers are doing (tested on Chrome, Safari, Opera and Firebug). In my mind this makes sense, because the web console is visually connected to the tab, so I would expect console operations from anywhere in the tab's contents to be interfering with each other. I can see some benefits in treating iframes differently, but I'm not sure if this is worth the deviation from what the rest of the web is doing?

Hmm, perhaps you're right. Seems odd that different frames can share that same state, but I guess that's never really a problem in practice (and only an annoyance even if it does somehow come up).

Did you get a chance to think about this some more? Can we land this?
