The HTML testcase as an attachment would be more useful than inline (and less clutter). Movies are less useful, not worth the space or time unless the testcase is unclear.
Status: UNCONFIRMED → NEW
Crash Signature: [@ OOM | small ]
Ever confirmed: true
Keywords: crash, csectype-dos, hang
Whiteboard: [sg:dos]
With e10s I was able to close the testcase tab, but the content process remained hung so the rest of my tabs were useless. I could quit Firefox from the menu and the windows closed, but both the parent and child processes kept running for a while. They did eventually quit on their own. In addition to the timeout/onload being an inifinite loop, the testcase does keep growing the content by adding another frame and onload each time. That's likely the source of the OOM crash reported in comment 2 though the stack is a little weird at the top: brotli doesn't call layout's BuildDisplayList().

Some considerations: 1- You can minimize the html code to the minimum expression: <a href="https://www.mozilla.org/en-US/firefox/new" onclick=" x = open(this.href,window,''); x.document.body.outerHTML += '\ <iframe src=https://www.mozilla.org/media/img/firefox/template/header-logo-inverse.510f97e92635.png onload=parent.top.opener.x.document.write(parent.opener.x.document.body.innerHTML)></iframe>'; return false;"> Page Locking </a> 2- The infinite loop occurs with parent.top.opener.x.document and not with parent.top.opener.document 3- The infinite loop occurs if the src of the iframe is an image (I've tested it with a Google image). If we upload any website, for example https://www.mozilla.org, it works correctly. Screenshot: https://drive.google.com/file/d/0B5G3cbs08P16dHp1MC1qU3hwMjQ/view 4- In Google Chrome the result is the same as in Firefox, but as each tab launches a separate process, the browser does not hang (you can use other tabs)

The testcase doesn't trigger on firefox anymore because it fails a cross origin check, you can fix that by changing the target to 'about:blank'. New version: http://swarm.cs.pub.ro/~cbadea/test/crash.html What happens is we get into an infinite loop where a page has an iframe that, when loaded, triggers a document.write() on the parent which in turn adds more iframes that continue the cycle. iframe = document.createElement('iframe'); iframe.src = 'about:blank'; iframe.onload = function() { document.write(document.body); } document.body.append(iframe); This results in the content processes almost freezing, however this is not different from just adding iframes in a loop: while(true) document.body.append(document.createElement('iframe'). Compared to Chrome, Firefox performs worse when the iframes contain images, with jank being noticeable in the parent process as well. I am not sure if we can fix this.
Flags: needinfo?(catalin.badea392)
Simple version (will hang your browser) without the image: http://swarm.cs.pub.ro/~cbadea/test/test.html
Switching tabs considerably reduces jank in the parent process, probably because we throttle background pages.

This is just an elaborate while loop that adds iframes. There isn't much we can do to prevent this.

Hi Johann, Please comment on this.
Flags: needinfo?(wleung) → needinfo?(jhofmann)
So, trying the examples from comment 16 and comment 17 I agree that this bug isn't as high priority as some of the other hang issues we're investigating. Generally it's still an issue that we spill over into the parent process in some cases. Our goal should be isolating content process hangs so that the user is able to stop running the script with the hang reporter. In any case, INCOMPLETE is definitely not the right resolution for this, the bug contains a valid reproducible example for what the bug description says (hanging the browser). We could at most WONTFIX it, but I would prefer to give this a low priority instead.
Flags: needinfo?(jhofmann)
The crash happens on the child process. The parent process remains responsive and it allows the closing and opening of tabs. The major problem I see is that, when opening new tabs, some of them will be assigned to the 'busy' process, which will not be able to load them. We should try to load new tabs only on non-too-busy content processes. The fix of this issue is definitely low priority.

(In reply to Johann Hofmann [:johannh] - On leave until October, slow/no response on BMO, DM me if urgent from comment #24)

In any case, INCOMPLETE is definitely not the right resolution for this, the
bug contains a valid reproducible example for what the bug description says
(hanging the browser). We could at most WONTFIX it, but I would prefer to
give this a low priority instead.

Would we get closer to a WONTFIX once Fission is enabled (limiting probably the hang to the content process of the bogus website) ?

The major problem I see is that, when opening new tabs, some of them will be
assigned to the 'busy' process, which will not be able to load them. We
should try to load new tabs only on non-too-busy content processes.

I assume this will get better with Fission ?

I don't see why it would.

(In reply to Olli Pettay [:smaug] from comment #28)

I don't see why it would.

At least we would not block other sites?

This crash signature is extremely generic, so having it attached to this bug, which is about a specific test case, is probably more confusing than useful.

Crash Signature: [@ OOM | small ]
Severity: normal → S3
Priority: P2 → P3

The testcase seems not to reproduce out of the box for me on a current nightly (thus fission enabled). Jose, are you still seeing this?
