Waiting for d35aaqx5ub95lt.cloudfront.net...

Post by vingtzwanzig » 2019-04-13, 21:20

On Duolingo, very occasionally they show this page after completing a lesson with a try 7 days for free button:

duolingo PLUS
No ads, no interruptions
TRY 7 DAYS FOR FREE

Waiting for d35aaqx5ub95lt.cloudfront.net...

The page freezes Pale Moon and it does not respond, when you press the X close button a dialogue pops up offering to kill the window as it is not responding. The status bar at the bottom left says it's waiting for the cloudfront thing. You can go to other apps, the desktop itself is not frozen, just the Pale Moon window.
After about 10 minutes it did eventually go past this page to the Duolingo home page. Running Pale Moon from the terminal did not reveal any error messages and CPU use was not abnormal while the freeze was occurring. Latest unstable version, 28.5.0a1 (64 bit) (2019-03-26) Adblock Latitude 5.01 PDF Viewer 2.0.961. It's happened a time or two in the past too whenever this page is shown. All the other Duolingo pages I encounter seem to work normally.

If you think it is d35aaqx5ub95lt.cloudfront.net that is the issue, are you able to block that in your adblocker?

It isn't a simple website with individual pages, I'm not sure how it works exactly. That cloudfront thing turns out to be one of the required domains, and is accessed at other times with no ill effects:
https://forum.duolingo.com/comment/1023 ... e-required
If I navigate to that address:
https://d35aaqx5ub95lt.cloudfront.net/
I see this displayed:
<Error><Code>AccessDenied</Code><Message>Access Denied</Message><RequestId>AD275384F91FCF59</RequestId><HostId>wQUgkMHXb9aD2boA9awk0q32lQBvZc38lBr/YHOpjd8eTor8r/8i5TQ/7DTQKkv8HufJ1TWTsEM=</HostId></Error>

So I guess it's some server with content that's dynamically provided to create the pages that are displayed as the lessons progress? Because as you complete each question in a lesson, the address in the address bar stays the same. I wonder if the duolingo adfree system conflicts with Adblock Latitude and actually turning off ad blocking would help, but it might not.

FYI: cloudfront is a CDN. It's possible the website owners have not set up their origin server link to the CDN properly yet causing delays or errors.

..or perhaps d35aaqx5ub95lt.cloudfront.net is blocked by some sort of security software/extension.
In this case, Norton Safe Web turned out to be the culprit:

I am using a fairly minimal Linux installation and don't have additional security software, just a fairly standard Pale Moon with the pdf and Ad Block Latitude extensions. The cloudfront CDN in question (which sounds quite like the NTP pool system, having now read a bit about that) can usually be successfully accessed, just not on that page. If my net access is running slow I can read various addresses in the status bar while the pages load. The odd thing from a Pale Moon perspective is that the entire browser locks up, you can't just close that tab or even switch to another, apparently the only ways out are to leave it until it eventually goes back to the Duolingo homepage, presumably on some timeout, or sigkill the Pale Moon process. I disabled Ad Block Latitude everywhere on Duolingo, and will see what happens like that, although the problem page may only appear every 2 weeks or so, it is pretty rare to be shown it. There aren't many ads shown on there any way.
Looking for built in blocking, there are a few settings in about:config that sound like they could potentially block things:
security.block_script_with_wrong_mime; true
security.data_uri.block_toplevel_data_uri_navigations; true
security.mixed_content.block_active_content; true
services.sync.prefs.sync.accessibility.blockautorefresh; true
I don't see any Google safebrowsing in there though.

OK, I will try to remember that, although I will have to enable it at the possible relevant point before the browser freezes. It wasn't anything to do with adblock latitude as it has happened again with that disabled for the whole duolingo website.

With a working Oracle Java plugin, this page worked. There was a moving display of some images and text that showed various offers which slid in from one side then slid off the other after a pause. Then I tried disabling the java plugin to see if that was really helping or the page had been fixed, and it sort of stopped then worked a bit. So I changed the view to js. I then tried switching the java plugin on again and the browser froze up and stopped responding to any buttons clicks or sliders, with the view shown, but the little diamonds in the background still slowly floated up the screen and one CPU core was fully occupied in top, I think it was xorg about 50%, 2 kworkers around 20%, and Pale Moon around 7%.
app-06b1b074.js is shown next to the cloudfront address. It looks possible the problem is something to do with java or javascript.

On this page a week ago it displayed the moving animations but jammed and would not respond to any button clicks, with the Oracle java plugin enabled. So the java plugin seems to help it display better but not fix the problem. That time it said:
looking up js.stripe.com...
transferring data from js.stripe.com...
I killed the browser. I wanted to do a save web page - complete but couldn't. I tried that on an ordinary Duolingo lesson session, when I tried to reopen the saved page it came up with a blank white page, so it must need to be run in a certain way, possibly with cookies involved to register some sort of state or progress. Looking at the js files I saw some stuff that looked like UA sniffing, so I set a custom useragent override for Duolingo:
general.useragent.override.duolingo.com;Mozilla/5.0 (X11; Linux x86_64; rv:60.9) Gecko/20100101 Firefox/60.9
After upgrading to the latest PM unstable today I got to that page again, which locked up the browser as usual. I looked in the .moonchild profile, in /run and /tmp but could not find any cached javascript files, I suppose it stores them in RAM for an active / current tab? So I haven't found exactly what content is being run at that point.
But I did run strace on the jammed Pale Moon:
$ sudo strace -p 5892 -o palemoonstrace.txt

It seems it sticks on a time request that keeps failing, probably from some piece of js, which I have not yet found a way to capture.
It also eventually stopped saying looking up this or that too.

I don't know why people thing that straces are in any way useful for debugging. They aren't.
strace traces system calls between the application and the kernel, which in no way helps to track down internal code issues.

OK, thanks, it adds some vague clues I think, but won't say much on its own. Other ideas I have to find out more are to install Chromium, and try to save the complete webpage, if it runs there, also if I can do it perhaps save the rendered html content as the displayed screen might be created from javascript and server apps. It would be ideal to get some saved snapshot that could be tested at will. I was just trying gdb on the running Pale moon, it freezes Pale Moon when attached but I can use bt to get a backtrace. Looking at the strace log it does show, in conjunction with the visual observation of the animations, there are several things going on, it doesn't just stop dead in every respect, although mostly multiple time requests at the start. Do you have any ideas to find out more another week?

Using Chromium with Duolingo, it asks questions that you need to speak into the microphone to answer. You don't get that with Pale Moon, even on the exact same lesson. This is just as well, because I don't have a microphone thus cannot use Duolingo with Chromium... :D

Searching the Pale Moon forum I found Duolingo has a settings page you can turn this off. Testing it to see if it worked then brought me to the problem page in Chromium :clap:
https://yadi.sk/d/euIJbVFYIbOIKg
That is a tar.xz of the web page which I did a save complete page on from Chromium, also I used the JSFiddle bookmarklet mentioned here which I previously installed to get the generated html, also included in the tarball after copy pasting it to a text file:
https://superuser.com/questions/414198/get-current-html-of-page-built-with-ajax-requests

Looking in Chromium dev tools it looks like the various java script files are indeed saved in the files dir of the saved page, although in dev tools I can view them unminified.
The 2 js files related to cloudfront (if that is even relevant) are these:
app-676b15de.js
vendor-af88618e.js

The files are fairly big. More data gathered, but does it help?

At the problem page again in Pale Moon, this time I had the dev console open in a maximized separate window, but when the main window stopped, that showed a white blank window, it had been working before. But here is some gdb output, I restarted PM and stopped it again and got a different backtrace, perhaps the multithread backtrace at the end is more helpful.

The Pale Moon window stops responding at this line:
22:40:29.147 > POST XHR https://m.stripe.com/4
But then some other messages are written on the console later, it still does not respond to mouse clicks. The XML Parsing Error message often appears when using Duolingo with no obvious bad effects at those other times. In the page source files, m.stripe.com is mentioned only once, in the file inner.html near the end.
$ palemoon inner.html
gives a blank page and the console says:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://m.stripe.com/4. (Reason: CORS header ‘Access-Control-Allow-Origin’ does not match ‘https://m.stripe.network’).
It seems to mostly consist of <script>javascript</script> within the html I think, it might not be that bit causing the problem anyway.
This is still with the java plugin enabled. I've now disabled it to see if it stops at the same spot or elsewhere, if I get to that point again with the right console page on view at the time :) .
Stripe? "Stripe is a technology company that builds economic infrastructure for the internet. Businesses of every size—from new startups to public companies—use our software to accept payments and manage their businesses online."
So the page is probably accessing Stripe and Duolingo code at that point.

Just a quick guess.

As mentioned, cloudfront is a CDN (Content Delivery Network) it is from Amazon's AWS. Many websites use cloudfront to offload images, audio, scripts, etc to segregate content in an effort to improve page load times, etc. My guess is that if Adblock Latitude is the only add-on you have and not NoScript it may have a filter there that is blocking the cloudfront URL. Try going into Adblock Latitude and see what elements or URLs are being blocked. If you have something like NoScript look in there, too. Absent of that, put Pale Moon in safe mode and see if cloudfront loads. If cloudfront still doesn't load then I'd investigate a network issue or temporally remove your prefs.js file letting PM build a new one then test again. Make sure you keep a backup copy of your original prefs.js.
If you're that smart and act like a dork, then you're not that smart after all. :geek:

Re: PM and Duolingo.com almost totally freezes together with Linux on one specific animated site[html5 animation?]

Post by vingtzwanzig » 2019-10-10, 19:22

Moderator note: Moved from different topic to this thread. It was off-topic in the other thread and hijacking it for -this- one. Please don't.

I had a similar problem here:
viewtopic.php?t=21862
The Duolingo site loads content from remote servers to display the pages, in addition to the actual code present on the web page. If you do a lesson you stay on the same page, even when the offer is shown, but the content is loaded to display the different 'pages' you seem to go through. I wondered if something was going wrong with that process due to some java script incompatibility. But it might not be that. Also I did get the animation working with a java plugin in Pale Moon and the page still locked up the browser totally, but was displaying the animation happily. And the same floaty stars are on other Duolingo pages which display OK.
What I have not added to that info was I also found a way to regularly trigger my problem page to appear - simply by starting Pale Moon in a fresh profile, so after 1 or 2 lessons they will show that offer page, which saves waiting all week.
I even made a short script to do this:
#! /usr/bin/bash

rm -rf "/tmp/pmtmpprofiledir"
mkdir "/tmp/pmtmpprofiledir"
palemoon -no-remote -profile "/tmp/pmtmpprofiledir"

But I haven't contacted Duolingo, (which might have been a good idea) and just resorted to closing all open tabs before going on there and then hitting the Pale Moon window close button until I get a window not responding - kill this app message.
Here's the console messages I get on your new page:

This error:

appears a lot on Duolingo pages, possibly that is relevant?
Both these pages are not locking up NTP's GTK3 unstable version as much as in earlier versions, as it's possible to change tabs after a ~10 second delay and then it works normally on other tabs so long as you don't return to that one.

Off-topic:
Oh, sorry. Please delete that post and this one too then, I don't really need my words recorded for all time in general, and especially not my mistakes!
On the old Void forum it was common for users and mods to delete posts on a whim, and the entire forum was eventually deleted too. :D
However there is no delete or edit button as it has 'expired'.
Incidentally, would it be better to have that facility?

I hadn't thought about it before but even FaceBook and similar allow that.

Off-topic:
When you post on a forum, ANY forum, you post publicly. Public information is going to be recorded for as long as the ones recording it retain it. If you don't want your posts to be public and recorded knowledge, then you should refrain from using public boards.
This is not social media where your posted content is under your (private) control. The GDPR does not apply.

The reason why we limit editing and deleting of posts is because if allowed indefinitely, it invites destructive behavior from those who "ragequit", often completely breaking dialog flow in threads by deleting/changing past posts. For those using the forum as a source of reference, this is disastrous. It is also limited to prevent spammers from necro-editing posts to slip in SEO links and other nasties.
