memory leak and too many open files about swiftshell HOT 3 CLOSED

I assume this is for stress testing purposes?

Each run opens 2 Pipes (for stdout and stderror), and each of those has 2 FileHandles. I assume this is where the open files come from. To test this, try using runAndPrint instead, it uses your application's own stdout and stderror.

Even so, I don't think the files should be kept open after the output from run has been discarded. I'm on Easter vacation for 1,5 weeks now, but I'll take a look at it when I get back.

After more investigation on this issue recently, the memory leak seems to be inevitable. Even if I create a simple Process without a Pipe and set its stdin, stdout and stderr to nil, it still leaks after its termination. The problem seems to be related to apple's own Process Api. However the open files can be fixed by closing all file handles after process terminates and it resolves the main source of memory leaks in my case.

Thanks, I'll look into having swiftshell close all file handles manually after a Process finishes.
