Stuck after a while

[thany]

Describe the bug The program gets stuck "downloading" (not really) after a while. I don't know what triggers it. I onlyknow that it gets into some kind of intermediate state, where it's not possible to either resume downloading, or stop downloading. It's in a kind of limbo.

Sure I can kill the process, but that will also kill any progress, causing it to happily download already-downloaded files, appending (1) to the filename to force uniqueness (which is totally bonkers on its own, but that's a different issue from this one).

So it's stuck. And here's how:

No CPU usage No GPU usage Very occasional disk I/O usage Almost no network I/O usage

The most notable thing is that it keeps 2 connections open:

DownloaderForReddit.exe (1844), <redacted hostname>, 53422, 199.232.149.140, 443, TCP, Established, 
DownloaderForReddit.exe (1844), <redacted hostname>, 53635, 176.56.179.186, 80, TCP, Established, 

And ONLY these two. If I kill these, the download process completes with an error Failed to save content without mentioning a reason.

Environment Information

• Windows 10
• Software version 2.3.4
• Are you running a compiled version or from source? -> Yes

To Reproduce (optional) Steps to reproduce the behavior:

1. Download
2. Download some more until the above happens
3. Pray to a deity of choice that your debug tools are running, because I can't tell you for the life of me how to reproduce this reliably.

For all but the most trivial of issues, please attach the latest log file.

Sure, but I think this line is what you're going to need:

    "name": "DownloaderForReddit.DownloaderForReddit.Core.Content",

Perhaps you meant http://None?", 
    "url": null, 
    "save_path": null
}

I don't know why the url for a perfectly normal an visitable url is being set to null.

You are using a long obsolete version of the software. The entire codebase was overhauled and largely re-written for version 3.0. Hopefully whatever was causing this issue has since been fixed.

[thany]

Maybe so, but 2.3.4 is the latest stable version... I'm not seeing a stable 3.x release, unless there's something I'm missing.

[thany]

@MalloyDelacroix Can you comment on the above please? A stable 3.x release and such? Otherwise am I not totally correct in using 2.3.4, as that's latest version that was declared stable?

[MalloyDelacroix]

The 3.x versions are technically in beta, but they only remain so because of issue #234 which falsely flags the app as a virus on Windows. The newest release is stable in all regards but that, and that issue appears to be intermittent.
