Memory Limit Exceeded Support about process_control HOT 4 CLOSED

This is a great idea. I've looked into it a bit, and it seems fairly straightforward on Windows, as expected. Unix will be more complicated but should be possible too.

However, I should point out that a programming judge would likely need a separate environment for user programs. There will always be a way to circumvent limits from this crate, potentially allowing programs to damage the system. This crate is mostly intended for trusted programs that might unintentionally exceed their limits, such as code run by test harnesses. Does that still work for your use case?

Yes, it does still work for my use case

I have mentioned the example of the virtual judge to get the idea across, but I am also running and monitoring a reliable process, which in the worst case can exceed the defined memory limits.

I think that feature can be useful in many other use cases.

I agree. This has been implemented in version 3.2.0 and will be released tomorrow. The API doesn't exactly match the one in this issue, since it resembles the syscalls offered by supported platforms. They cause allocation to fail if the memory usage would be above the memory limit.

Also, MacOS isn't currently supported, since it doesn't offer syscalls for limiting memory usage.

Version 3.2.0 has been released with Control::memory_limit, so I'm closing this issue. Let me know if you have any issues.
