download sometimes starts, never ends

ntoskrnl

Also 100% reproducible with this PDF file (datasheet):

http://www.lighting-spot.com/pdf/HL296HO-IS-UV-W.pdf

This issue only occurs if you attempt to start the download by clicking a link. There is no problem if you paste the address in the address bar.

Another aspect is that if you open the link in a background tab, and then switch to that tab, there's something weird going on (the download is not offered and the tab has no address in the address bar, although it does download if you press refresh).

Vivaldi v4.1.2369.10

Download in mixed content environment cause this. Mixed means opening a link without SSL (the http://...) in a page with SSL (the https://).
Some new Chromium 92 core security feature Vivaldi inherits.

I think, for you context menu "Save link as… " should work.

Pathduck

@doctorg Good point about the mixed content

It might indeed explain some of the weird behaviour we're seeing in Vivaldi where downloads never finish. But I don't think it explains it every time.

What's weird is that for instance downloading the above PDF (insecure link) will trigger it to be a stuck download in the panel. While doing the same with the EXE on last page (edited the url to also be insecure), will simply block the download (as it should), and no stuck download.

Do you know if the developers are aware of this problem and are working on a fix? Or even better, if they are planning to scrap the entire "download warning" feature?

They know about the issue, i hope they investigate the next days/week.

As this is a chromium core feature it is not so easy to remove it.

Pathduck

@doctorg Thanks, we will see, hopefully soon this feature will be dead.

Yes, but like I've mentioned earlier, it does not even behave the same in Chromium any more, it looks like this at the bottom of the page:

So the Vivaldi code is the old behaviour in Chromium.

Edit: I made a video to show the different behaviour I mentioned between EXE files and PDF files.

@pathduck Perhaps Chromium has a blocklist for executables and for less insecure files it tries to download.

I never found out how download worked and i have no time to inspect the large Chromium sources.

since //downloads is shown as a page, might not the warning box be a frame - and the problem related to this? :

@fritzli The chrome://downloads is not a part of the Vivaldi UI, it's part of the Chromium base. The URL just changes to vivaldi://. It is not accessible from the Vivaldi UI and is not meant for Vivaldi users to access. In this specific case it is useful to have for troubleshooting the issue though.

I doubt the iframe issue is involved at all. Iframes are used in web pages, while this warning we're talking about is part of the Chromium base UI.

But good on you for thinking outside the box, it's a good quality

a download that doesn't start I get going with <RC-save link as>
in ://downloads the first discard/keep dialog appears.
choosing keep brings up the confirmation dialog. Choosing keep here does nothing until the download is complete . before that X (only?) will dismiss it and the download will still hang. Once the download has completed the keep / confirm keep works as intended and the file is renamed and available.

fritzli

when I left click on a download button and it doesn't start the downloads panel pops up but the new file in question does not show - neither does it show in //downloads with any warning.
Once I do get it underway with right click - save link as then
the link says https in the //downloads screen (chrome UI) but just http in the panel and also when I hover over the download button (vivaldi UI).

New 4.3 is out with SO-good-looking download panel (c), but this bug is still there $:\$

rubenalamina

Confirming this still happens in the latest 4.3 version. I have resorted to pin the vivaldi://downloads page while dealing with files from old servers that I need to download. What happens is still the same:

Click on a link to trigger a download but nothing happens. When you get the save dialog or trigger the download start automatically depending on your settings, it will go on indefinitely once it reaches the full file size. Only way to have it "finish" is to go into vivaldi://downloads and click on keep since there will be a dialog there not shown anywhere else, which is the main problem for everyone.

DoctorG

A security core feature does not allow download of http:// URLs in a tab which opend with https:// URL.

Workaround: Open such http:// URL with Shift+Click in foreground tab and hot Save as…, that will save your download.

@doctorg Annoying bug, how to disable this security core feature?

how to disable this security core feature

I fear, not so easy, too much work and troublesome for the small Vivaldi dev team.

rubenalamina

@doctorg The issue most have with this is not the feature itself, is that the dialog that the user should be getting when attempting a download like that is not shown at all and the download silently fails. Or the dialog is not shown, download starts but never completes because the user needs to select cancel or keep in the dialog that is not being shown.

At least there's the workaround of opening vivaldi:downloads to be able to see the dialog. There's something to be done for sure, it's not a proper way to handle a feature like this.

DoctorG

@rubenalamina If you think such feature is useful, please read Request New Feature, open forum Feature Requests and post request.

And read Help us to reproduce the issue carefully and then report bug to Vivaldi tracker.
