There was a problem hiding this comment.
This code has always bothered me - it's more complicated than a redirected command.
I wonder how possible it would be to move most of this logic into a helper method and avoid generating so much complicated code.

Fix #4812
Summary
When handling file redirection for CommandExpression, we don't call 'DoComplete' on the underlying
PipelineProcessorof theFileRedirectionobject, and thus theEndProcessingmethod is not called onOut-File, which causes different behaviors between<expr> > out.txtand<expr> | Out-File out.txt.The fix is to make sure 'DoComplete' is called after the stream output has been written to the redirection pipe.
Also fix another issue
This PR also fixes an issue that could mess up restoring the original pipes. Here is the repro:
The root cause is that we don't always restore pipes in the correct order. Please see the code changes in
Compiler.csfor more details./cc @mklement0
