Operating system: CentOS Linux release 8.2.2004 (Core)
SonarLint plugin version: v3.11.0
Programming language you’re coding in: PHP
Is connected mode used: No
Connected to SonarCloud or SonarQube (and which version):
And a thorough description of the problem / question:
It works for some files (which are about 200 lines), but for some particular files(1548 lines), it hangs forever(and cpu usage of the process is 100%).
Hello, welcome to the community! And thanks for reporting this.
I suspect that there is a construct in this file that is not well supported by our PHP analyzer. Would it be possible for you to privately share (e.g by private message on this forum) the offending file?
Could you also please share the value of the sonarlint.rules property in your user settings? This could help us check whether a particular rule has a performance hotspot.
Sorry I cannot share that file. I’m using the default rules by the way.
After some investigation(trying to remove/modify line by line), I found it’s able to avoid this problem by removing long text which may also cause the linter to produce “0 issues”. Here is an example:
Set sonarlint.output.showVerboseLogs and sonarlint.output.showAnalyzerLogs to true in your user settings
Open the SonarLint Output (“Command Palette” > “SonarLint: Show SonarLint Output”)
Clear the output using (“Command Palette” > “View: Clear Output”)
Open the offending file
Copy and paste here the content of the SonarLint output (enclosed in tripled backticks like this ```)
I did not manage to reproduce the issue with the reproducer you shared, however with a longer line I got the following:

In the log above, there is one line that tickles my curiosity:

This could explain why you get 0 issues (although it does not explain the 100% CPU usage).
