Unfolding not always possible

[DarkLite1]

Issue Description

Since the last update of the PowerShell Preview extension there is an issue with unfolding certain code blocks. When refactoring some code you will see that pressing CTRL + 0 will collapse all regions but sometimes it's no longer possible to expand the regions by clicking on the arrow in front of the collapsed code. When doing this nothing is unfolding and after 10 to 15 seconds it does unfold sometimes, but not always.

It's pretty hard to replicate this as it happens randomly but quite often. Usually I run a Pester test script to test a script and then when I come back the folding becomes an issue.

@DarkLite1 is there anything in the logs suggesting an error?

[TylerLeonhardt]

Also a sample script that you've seen this with would be very helpful.

[DarkLite1]

I knew this question was coming ;) It's just very hard to consistently reproduce, but it happens quite often as in every 2 times after refactoring code.

I've add some test code in attachment. When both files are open and you are in the file ``Set permissions.Tests.ps1and pressF5` to execute it, everything goes fine. Than you refactor something in the production file or the test file, press `CTRL + 0` or try to unfold a specific section and it will fail 1 out of 3 times. What's also not working is formatting code after refactoring, copy/pasting a pester `it` clause for example. When you do that and press `ALT + CTRL + F` nothing is happening for a while.

I hope you guys (or girls) see something I can't see. Thanks anyhow for looking into this and sorry for not being able to be more precise.

Figured out how to reproduce this:

1. Open the file Testie.ps1 in attachment
2. Collapse all by using CTRL + K and CTRL + 0
3. Open the top comment section of the file and add some random text in the comments or simply change the e-mail address in the last line AUTHOR SomeoneElse@ms.com
4. Try to click on the arrow before Process{ to unfold it
   Notice that unfolding that section is impossible

I can confirm this is something that started in the last release (preview@2020.2.0).
But it's not an unfolding problem, it's everything the extension do hang for a long time.

To reproduce do the steps @DarkLite1 provided in his last post.
Add to step 4 more things like F8 on some line and hover over a variable to get the intelligence tooltip.
The unfold will not work, the F8 will not execute and the tooltip will say "Loading..."
Then wait for ~1 minute, it will suddenly unfold, Run the F8 and show the tooltip info.

BTW is 2020.3.0 already on the way? Or can this be fix before that?

[rjmholt]

Does it work if you go into the console and press Ctrl+C?

Does it work if you go into the console and press

Ctrl+C doesn't seems to effect this.

[rjmholt]

@DarkLite1 could you post your example as text?

I can confirm this. My observation is that extension spends a lot of time to analyze PS Script Analyzer along with my customized settings for it.

My observation is that extension spends a lot of time to analyze PS Script Analyzer along with my customized settings for it.

Can you expand on this? How did you observe this? Does it seem to be interacting with folding?

@rjmholt It's simple:

1. Launch VSCode
2. Load ps1 script which has functions/foldable regions
3. Immediately start clicking multiple times at the fold 'arrow', folding/unfolding is not possible
4. In the background, Powershell interactive console is starting and with it, PSSctiptAnalyzer starts to analyze code
5. When PSSctiptAnalyzer display list of problems at "Problems" tab, folding/unfolding is possible again
   Hope that this helps.
