Issue descriptionUserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.94 Safari/537.36 Steps to reproduce the problem: ** DO NOT CLOSE BECAUSE "CAN'T REPRODUCE" ** The very nature of the issue prevents me from figuring out what is triggering it, hence I cannot provide an easily reproducible example. However, what happens *SOMETIMES* is that: 1. I visit a page where presumably some element (a script or image or stylesheet or whatever, the only sure thing being that it's NOT the html page itself) takes very long to load, perhaps even times out. 2. I look at the Network tab in the Developer Tools What is the expected behavior? To start with, it should never, ever happen in the first place that the "Loading" animation on the left next to the title of the tab keeps spinning forever, unless (a) the page itself is infinite, or (b) some script continuously keeps adding content that needs to be loaded, or (c) some element in the page (image, css, script...) is infinite in size. If some request gets stuck and takes forever to get a response, it will eventually time out and fail, and hence the "loading" animation will stop. ANYWAY, **if** something in the page is really taking forever or very long to load, then there **MUST** be some request in the Network tab of the DevTools whose status is listed as "(pending)". What went wrong? The "loading" animated icon in the tab keeps spinning forever, yet there is no request in the Network tab listed as "pending". All of them are listed with http response codes, which means that all request are finished (whether succesfully or not). Did this work before?

If you can reproduce this with relative ease, can you please give us a dump of: chrome://net-internals/ ? This file will contain sensitive data! So please only do this if you are OK with us seeing this data. Please send it to allada@chromium.org. DO NOT POST IT HERE! Thanks!

Unfortunately I cannot reproduce it with ease. When I reported this bug I was observin it systematically on a given website, but after restarting Chrome it stopped happening. It wasn't the first time I observed it, though. If I see it again (and if it keeps happening when it starts) I'll send you a net internals dump. However it may not be anytime soon, so I'd suggest not to leave this bug in Needs-Feedback status, otherwise it's likely to expire.

Duplicate of a previous issue. Essentially, if all network requests are good and the spinner is stuck after a while then some script is stuck in a tight loop. Reloading will either reveal the issue or fix it, but there is no way for the DevTools to help with this since you'll be jumping in halfway through execution. This means DevTools isn't in the position to pick up on what is going on.

What do you mean by a "tight loop"? If the script is loading something, the pending request should show up in DevTools. If the script is doing anything else, there's no reason why the icon should be spinning. There's no way this can be possibly right.

By the way, the other issue seems to be about opening the devtools when the icon is already spinning. I observe the issue even with the devtools already open.

Also, this is not only about not being able to figure out what's going on in DevTools. It's also about the icon spinning forever in the first place, which as I pointed out is something that just can't legitimately happen, except if: > (a) the page itself is infinite, or (b) some script continuously keeps > adding content that needs to be loaded, or (c) some element in the page > (image, css, script...) is infinite in size. and I can tell for sure that every time I have observed it, none of those was the case. |
