Read-Host paste dropping letters after F8/F5

[ili101]

Issue Type: Bug

This is similar to fixed bug #2291
On the original issue it was happening every time Read-Host was used.

Apparently now it happens only if you F8 or F5 (Run anything doesn't matter) then F8 or F5 again this time with Read-Host and paste something.
Random characters from the string pasted will be missed.
If you Enter/Ctrl+C between the 2 actions this doesn't happen.

I'm also struggling with same issue, I believe it is related: pasting text to integrated PS console keeps dropping/replacing characters. I copy credentials from password app, and use right mouse click to paste.

In the image at the left you see GUID pasted to PS integrated console and the beginning is strangely messed up, haven't figured out any logic what it is doing there. Next I pasted it into Notepad and that is correct.

If I paste to PS integrated console, then backspace to remove the incorrect string, and paste again, it pastes correctly. There isn't a constant repro, as usually it works. I haven't been able to figure out what triggers this, but I feel it is happening more often on fresh consoles. Killing console and opening a new one doesn't guarantee a repro, though.

When the issue occurs, I also see the missing characters outputted at the end on the blank command line, as in OP video.

@jpalo Yes looks like the same thing. 100% reproducible for me also with Get-Credential

Bug regression - this was fixed in stable in 2020-2021 but is happening again in PowerShell Preview (tested on v2022.3.0)

@ili101 Can you test the build I just posted in #3876 (comment)? I'm not sure if this is the fix for this issue, but would like to see...

[andyleejordan]

I don't think that build is going to fix your issue, it seems separate. Like, I just repro'd it. Very strange.

[andyleejordan]

How big an issue is this for you @ili101, is it blocking any scenarios or can you just call Read-Host interactively and paste that way?

[ili101]

@andschwa Did some more testing (with the build you mentioned).
No problem when using terminal directly without F8/F5.
With F8/F5 when typing it will miss the first letter.
With F8/F5 when pasting unpredictable.

I think it's maybe related to #3881

[andyleejordan]

Feels like a repeat of #2291

Rewrite part 2 coming up? 🤔😁
Just an uninformed idea, will it be easier or harder to use the VSCode input thingy instead of the terminal for input?

[andyleejordan]

...that's a brilliant idea. We'd need to rewire Read-Host to send a message over LSP to ask for input, and then handle that in the client...but doable. @SeeminglyScience add this to the list of ideas! I think it'd make for a really nice UX.

[andyleejordan]

Hi there, we just released v2022.4.0-preview! Could you please try PowerShell Preview for VS Code and verify this is fixed? It seemed to be in my testing, so marking as resolved, but please let me know if it's still occurs (or if new bugs show up)!

Rewrite part 2 coming up?

It happened!!!
