Syntax checker not detecting change of files.

[jhoneill]

Prerequisites

• I have written a descriptive issue title.
• I have searched all issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

I can not see this as an issue and I think it is the extension but it may be VS code itself (if so I'll close this and and open there).

I'm working with some scripts which generate other PowerShell scripts, so the process goes

• Edit generator or Edit instructions in VSCode
• Run the generator script from the PowerShell integrated console
• Edit the resulting code

What I'm finding is the error highlighting is marking thing in the text as errors which were in a previous version. What seems to cause this is the change made to the file outside VS code, as if there is a copy cached, which is still used when the updated file is opened.

Steps to Reproduce

1. Add extra lines containing a syntax error to an otherwise valid file. Problems should be displayed correctly
2. Close it, and edit it outside VS Code to remove the error
3. Reopen in VSCode and note the problems show before are still show. (see Visuals below)

Postscript - this also seems to impact folding. If the file has changed in the middle folding tries to fold were the old file should have folded.

@jhoneill thanks for the issue report...if you edit the open file at all in VSCode, does this problem go away?

[jhoneill]

No - not quite.
I opened the file in notepad and vscode.
I made a couple of breaking edits an extra } at the end and unused variable , saved & closed, in Code, and then saved from notepad to back out out the changes.
If I add and delete spaces at the end, it stops complaining about the extra } but nothing seems to get rid of the complaint about the unused variable, and folding is off by one line as if the extra variable line is still there.

And if I close and re-open the file it adds an extra instance of the erroneous message each time

@jhoneill the latter is sadly known: #3252

@SydneyhSmith the bot shouldn't have closed this - do you need any more repro info ?
