"Oh, no!" error page when uploading a package with an invalid license URL

[claycompton]

To repro:

1. Create a package with an invalid license URL. I was able to reproduce this behavior with a URL that was over 4000 chars long.
2. Attempt to upload the package using the Gallery UI.

Result: After the initial package upload, you'll receive a WSOD. Investigating the error logs reveals that we don't handle the EntityException that gets thrown. For the full stack trace and error details, see https://qa.nugettest.org/Admin/Errors.axd/detail?id=3774.

Expected: Package validation errors should be presented to the user ideally in a way that resembles form validation errors. In any case, though, we shouldn't white-screen.

If the only invalid case is an url that is over 4000 chars long I'm going to vote won't fix.

I agree with @claycompton here... We use validation for a reason. If it's not working, we need to fix it.

[TimLovellSmith]

Validation works. This is just an edge case. URLs don't normally run 4000 characters, so I think the rational allocation of bug to milestone is this goes to up for grabs.

We need to validate all package metadata to ensure it matches the requirements of the database fields. For example, if I upload a package with a bogus version, what happens? etc.

I'll take a look.
