Will this work with runspaces?
mrboring opened this issue · comments
Hi
I've got some modules that use Foreach-Object -Parallel and Start-ThreadJob. I did a quick test and it does not look like Profiler analyses code in runspaces. Is this correct?
Thanks.
Did not try that. Would help me if you posted a simple repro. Are you seeing a ton of debug output when running your scripts even after running warmup? If so this would be a symptom of failing to hook the profiler in the runspace. It replaces TraceLine method during runtime and it does not fully work on first run in PS7.
I'll try to put something together to reproduce the issue.
The built in profiler that will ship in PowerShell 7 somewhere in the future will work. I am planning to upload a build from the respective powershell repo branch, so people can just download it when they want to play around with it, it tracks runspaces.
The hack I am currently using plugs into TraceLine which does not run in the other runspaces.
