Refactor Test-Connection by vexx32 · Pull Request #10044 · PowerShell/PowerShell

vexx32 · 2019-07-01T23:10:00Z

PR Summary

Refactor the Test-Connection cmdlet according to PowerShell/PowerShell-RFC#172

PR Context

Resolves #6768

NOTE: Currently this changes the pattern from Ping.Send() to Ping.SendAsync() with a manual event handler. This is due to a bug that was only recently resolved (see https://github.com/dotnet/corefx/issues/38770#issuecomment-507788270)

We can return to the simpler Ping.Send() pattern once we hit .NET Core 3-preview8 per the comment in that issue. 🙂

TODO:

Cleanup verbose messages
Add tests

Additional suggestions:

Add sequence numbers or timestamps to the standard PingStatus items so it's easy to see the order they were received in. Test-Connection Changes PowerShell-RFC#172 (comment) - @bobfrankly
Add the ability to ping all IP addresses in a given CIDR range (DDoS concerns maybe?) - @romero126

PR Checklist

Simplify some variable declarations, fix up some uber long lines, etc.

& some misc cleanup. Implementing IDisposable allows us to put the Ping() instances used everywhere into a single field and dispose it whenever the command is.

Kinda in the name aight?

@vexx32 Please move all style changes in 1,2,3 new simple PRs.

Also I think it makes no sense create a workaround with async if we get Core Preview8 soon.

Not sure it even makes sense to split style changes to be honest as this changes / rewrites a heck of a lot that I would cover in a style PR anyway.

We're still blocked on preview6 so I'm leaving the temp fix in for now so we can trust test results. When we get preview8 it isn't difficult to switch the pattern back.

iSazonov · 2019-07-03T11:25:15Z

Have pity!😭 We have open about 50 PRs...

vexx32 · 2019-07-03T13:19:29Z

I know. But is one of these better, or four for the same thing? 😕

If you'd really rather extra style PRs I can probably look to trim some of that out, but in a lot of ways the style changes are kind of tied into the rest of the changes. Let me know what you'd prefer! 😊

iSazonov · 2019-07-03T13:44:50Z

@vexx32 You will spend some time for temporary PRs but save a lot of time of reviewers.
It's incredible that someone can view more than 400-500 changes at a time.
After PR exeeds 100 changes, any style change significantly slows down the code review and begins to annoy.
While the PR draft you could make temporary PRs. I see many renames.
Also you could split functional changes too, ex. separate ping, traceroute and etc. to different PRs.
As for async, we get Preview7 in 5 weeks. I suppose we have nowhere to hurry.

vexx32 · 2019-07-03T13:46:31Z

Yeah, I guess that makes sense.

I'll look to do a style pass and see how I can split it out from there. Thanks! 💖
I may keep working in here till I see what I mucked up in the tests but as soon as I have this sorted I'll start splitting. 🙂
