Crashing Chrome

[kbowerma]

Description:

Sometimes my github (not necessarily issues page ) seems to lockup and nothing on the browser tab works however the other tabs seem fine. I have a lot of windows and several tabs open.

Requirements:

Please investigate and let us know if you are experiencing it to. I also have zenhub extension running

_update several minutes later_ I think this is related to zenhub because although it was not crashing it was very slow to respond. I just disabled zenhub and now it every char a type is realtime.

[cwdcwd]

ah ha! what does Zenhub inject? perhaps there's a conflict between the two?

[kbowerma]

it is not zenhub, I removed it. My work around is to have github open in an incognito tab which does not have blib enabled. But we will have to figure this out since it will happen with others too.

[cwdcwd]

Can you pop open a console when you see this happen and see if there's any errors or something loggin out?

[kbowerma]

I will keep looking but this is what I have so far:

content_script.js:57 Uncaught TypeError: Cannot read property 'appendChild' of nullinjectStyles @ content_script.js:57(anonymous function) @ content_script.js:67

And there is line 57: document.body.appendChild(node);

/**
 * Try to inject topcoder buttons on issues list and issue detail page.
 * This is infinite interval, because page content can be updated dynamically
 * (when new comment is added or because of html5 navigation).
 */
function injectStyles() {
    var node = document.createElement('link');
    node.rel = 'stylesheet';
    node.href = chrome.extension.getURL('styles/style.css');
    document.body.appendChild(node);

I repeated the same steps in my incognito window and don't see the error

[cwdcwd]

interesting. so that's where the style sheet for the button gets injected into the page.

The incognito thing is interesting. Can you dump me your list of extensions and see which ones are enabled/disabled in incognito mode?

[kbowerma]

sure will. I am sure it this extension but it can be very intermittent What happens is git is open for a long time. It just gets slower and slower until every char typing takes about a second to display. Could be network related? other times it works ok light right now.

thanks for that. So the ext's content script runs at "document start" (see this). I wonder if, because of github's background polling for updates, it's firing constantly. When you inspect the page, is that injection putting tons of link tags in? that's all speculation as none of that explains the incognito working out.

[cwdcwd]

FWIW I recently disabled "Markdown Here" as it was grinding everything to a halt at random times

[kbowerma]

that might be it. Like I said on the phone it seems like it may have fixed itself. I will close this ticket and we can open if it comes back.
