Can't download entire main.client.bundle.js

[DamianFekete]

Summary

Functionality is not working as expected (e.g. deselecting JS engines, seeing the entire test code)

Expected behavior

Receive the entire main.client.bundle.js file ( 635 kB)

Actual behavior

Received only 65 kB bytes.
Opera reports net::ERR_INCOMPLETE_CHUNKED_ENCODING, curl curl: (18) transfer closed with 538030 bytes remaining to read

Steps to reproduce

curl -vO https://test262.report/main.client.bundle.js

Can you be more specific, re: the functionality that is not working as expected.

[DamianFekete]

I guess most of the functionality doesn't work taking into account that I only get 10% of the JS file that is needed for the page.
E.g.

• Deselecting a JS engine doesn't do anything visible

• Clicking on the calendar or the arrow next to it doesn't do anything
  

• Not all code is visible and I can't scroll to the bottom

[rwaldron]

The test code file you see displayed is only for reference, it's not used for testing. The actual testing is done via automation on a private server.

@DamianFekete is referring to the bundled javascript file that is produced during the build of the site.

Nginx reports the Content-Length (filesize) as 635969.

➜ curl -I https://test262.report/main.client.bundle.js            
HTTP/1.1 200 OK
Server: nginx/1.14.0 (Ubuntu)
Date: Wed, 06 Jan 2021 17:31:02 GMT
Content-Type: application/javascript; charset=UTF-8
Content-Length: 635969
Connection: keep-alive
X-Powered-By: Express
Accept-Ranges: bytes
Cache-Control: public, max-age=0
Last-Modified: Tue, 06 Oct 2020 15:59:08 GMT
ETag: W/"9b441-174fea34922"
Vary: Accept-Encoding

...when attempting to download the file the server stops short of delivering the whole thing (with curl and with firefox/chrome/etc):

curl -SsL https://test262.report/main.client.bundle.js | wc -c 
curl: (18) transfer closed with 538030 bytes remaining to read
97939

As this file contains all the functionality for the site, the site is broken for users who experience this behavior (I am seeing it too).

The nginx error logs on the server running the site should show something obviously wrong.

Oh!! I occasionally encountered this and didn't find what is happening. Really great catch!!!!

[rwaldron]

The test source frame occasionally not resizing correctly (and appearing "incomplete") is the result of an odd race condition that I couldn't pin down in ever browser, for every file, and which wasn't worth investing a ton of time in because it usually just needs to be refreshed.

Whatever you're trying to accomplish by downloading https://test262.report/main.client.bundle.js directly is not supported.

[DamianFekete]

@rwaldron, it seems we're on completely different wavelengths, and I don't and can't understand why.

Whatever you're trying to accomplish by downloading https://test262.report/main.client.bundle.js directly is not supported.

Nobody is trying to download the JS manually and use it. Downloading with curl was used just to show the error.
I've already added a screenshot where I've opened the test262.report page and the browser itself tried to download the JS file and it couldn't do it. Even after multiple refreshes the "logic of the site" can't be downloaded.

@boazsender, @isaacdurazo, can you help?

[isaacdurazo]

Hi @DamianFekete, apologies for my late response. I want to confirm that after a few tries I was able to reproduce the issue. I asked my colleagues to help us address this and will give you an update as soon as I know more.
