(#3228) Process .Net 4.8 installation earlier in program execution #3789
Conversation
|
For our future selves: When I said "where I think this is happening (or at least relatively close)" in #3228, what I mean by the relatively close part is that if I set the .Net registry key such that Chocolatey CLI will fail with this error, Visual Studio will not load properly, and so debugging is not really feasible. However: the logs all encounter this error during the container registration, so the change I made is to verify the .Net version before container registration. One side effect of this is that termination of the program occurs before Chocolatey outputs it's version information, however given that the alternative is for it to terminate before Chocolatey outputs it's version information with an altogether entirely unhelpful error, this seems like a happy middle ground. |

There are instances where .Net is not installed in a way that allows Chocolatey CLI to function. In these scenarios, the version in the registry seems to be very old. This commit accounts for this by wrapping the container registration in a try cath, and displaying a descriptive error in that case. Additionally, this changes the check to use Registry64 instead of Registry32, as on 64 bit systems the 64 bit registry is the one that determines the .Net version. And the lookup on 32 bit systems gracefully falls back to the 32 bit registry.
This updates the .Net version Pester test to use the 64 bit registry as that is the one that Chocolatey CLI is using. Further, it adds a test for the .Net version to be a low integer instead of deleting it. It's been found in some scenarios where the version is there but low .Net misbehaves. It also adds a retry onto taking ownership of the registry key as we've seen instances where it fails to take the ownership and so the test fails. This retry should hopefully resolve these sporadic failures.

I mixed up the version from the config, so a number of the tests failed. I've updated the description with the latest Test Kitchen runs. |

Description Of Changes
Update the check for .Net version to happen before the container is initialized.
Motivation and Context
If .Net is sufficiently old, the container initialization fails and does not provide helpful context.

Fixes #3228
Reason for Draft
I am still validating the Test Kitchen tests, and working on if others should be added.
