Crash closing browser after zooming after upgrading

Postby hyzerfool » Fri Oct 04, 2024 12:38 pm

If a user closes a browser after zooming in, we hit a fatal error (callstack and log far below). Any suggestions will be deeply appreciated.

We are trying to upgrade from 116.0.15 to 128.4.12. This bug does not occur in 116 for us. We are a Windows MFC program using multiple document interface and the user can open / close multiple browsers.

I noticed that closing browsers wasn't working quite the same in 128 as 116 and I have changed our closing in response to that, which muddles the question of whether our crash is due to zooming whether the crash is due to my breaking things by closing browsers incorrectly.

In 116:
1) Make a note in CMainFrame that we are about to kill a browser
2) Call m_pBrowser->GetHost ()->CloseBrowser (true);
3) DoClose is called, we return false so WM_CLOSE will be sent
4) CMainFrame handles WM_CLOSE and calls m_pViewBeingDestroyed->RemoveView (), which calls DestroyWindow on our view (browser's parent window)
5) This leads to OnBeforeClose being called and the world is a happy place.

In 128
1) Make a note in CMainFrame that we are about to kill a browser
2) Call m_pBrowser->GetHost ()->CloseBrowser (true);
3) DoClose IS NOT CALLED
4) OnBeforeClose is called before WM_CLOSE is sent (I have a breakpoint in PostMessage via the magic of microsoft's Detours library, which I love). OnBeforeClose is called deep underneath WebContentsImpl::Close()

WM_CLOSE is not sent (except later on when I close the CChildFrame, then WM_CLOSE is sent once per browser we closed) so I wasn't finishing closing my browser's parent window. This is the callstack for when WM_CLOSE is finally sent:

So I modified things and close the browser's parent window from OnBeforeClose and simply kept track of how many WM_CLOSE's we expect and received and, while it felt exceptionally clumsy, it also seemed to work. Until now with the zoom crash.

Re: Crash closing browser after zooming after upgrading

Try --disable-chrome-runtime first (while it is still around). If this passes, it is probably because now chrome runtime is the default.

DoClose will be called with Alloy style browsers. You will likely want to use that. See https://github.com/chromiumembedded/cef/issues/3685

Thanks for the tips. My immediate solution is to upgrade to 125 for our next release (where our browser closing works correctly), which gives me time to learn about the shiny new things after that...

Re: Crash closing browser after zooming after upgrading

Postby hyzerfool » Tue Oct 08, 2024 3:08 pm

For anyone else who might hit this, we ended up taking magreenbatt's suggestion and using alloy style browsers. In our case, at least, the complete work to achieve this was to add:
Code: Select all
info.runtime_style = CEF_RUNTIME_STYLE_ALLOY;

before calls to CefBrowserHost::CreateBrowser

As far as I can tell, this has fixed our close browser issues and the zoom-in crash.

Very much appreciate the help!
