Background

  • Operating System: Manjaro Linux kernel 4.19.78-1-MANJARO
  • CKAN Version: 1.26.4
  • KSP Version: 1.8.0

Problem

When downloading large-ish mods, on my ADSL internet connection, after an unkown number of seconds which i suspect could be precisely measured and reproductible, CKAN crashes, vomiting a huge stacktrace. Upon investigation, seems like it's a TCP timeout issue, altough the download progresses (and i can indeed download the incriminated file outside CKAN).

Of course, this exception should not be raised, since the download is progressing at a steady pace.

Steps to reproduce

  • Go to my house, or any house with slow internet (1MB/s or so)
  • Install CKAN via the AUR (UPDATE: running a downloaded ckan.exe gives the same results)
  • Click on any large mod (>= 100MB), then proceed to installation, wait for what feels like 1 minute...
  • See error, if you launched CKAN in a terminal. Otherwise, nothing.

Expected behavior
Of course, i would expect CKAN to continue downloading. However, I suspect the issue is more on mono's side, but i'm far from even begining to understand C#'s ecosystem...

You will find the complete shell session below:

~ [255] $  # 255 is the return code of the ckan invocation, but i guess that won't help you, looks too generic to me

Of course, i will end this bug report by thanking you for your work.
I would like to help, but i'm afraid C# is really too alien to me. If you have requests i could assist with, i will do my best to answer them.

We should be smarter about raising download errors / re-raising the error popup in general:

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.InvalidOperationException: The form is already displayed as a modal dialog.
