runtime: Hang in ReinitializeConsole while waiting for child process exit
I’ve been getting reports of an intermittent hang in MSBuild running on Linux in the dotnet CLI build process. Original report with a fair amount of debugging info in case I drop something in this summary: https://github.com/Microsoft/msbuild/issues/3563
In two instances that I’ve observed, my process is hung in HandleToolNotifications, a method that waits on several ManualResetEvents that are triggered by event handlers hooked up to a Process. The process on which it’s waiting is in “zombie” state, waiting to be reaped by its parent.
In both instances, a thread running MSBuild code has called into a WaitHandle.Wait* method, and that thread appears to be handling a signal and calling ReinitializeConsole. It’s hung on a write inside that.

This is how the terminal works in a docker context:
Create container, allocate terminal (-t):
The id of this container is
81338bfd0463609f43274c696ff90febcbe6c296c5a43ef8f291f09b1857f79d.As part of creating the container, docker created a shim process.
This shim is the ‘terminal master’: it reads what comes from the standard out in the container. This is passed via a named FIFO
init-stdoutto thedockerdprocess:I’m having another look at this.
In the kernel I see this: https://github.com/torvalds/linux/blob/bab5c80b211035739997ebd361a679fa85b39465/drivers/tty/vt/vt.c#L1814-L1815
Because there is a lock involved, this may mean it is not safe to change the mode from a signal handler.
We can move the ReinitializeConsole call from the signal handler to the SignalHandlerLoop thread. This is functionally the same. Then we can observe if that solves the hanging cli builds.
