Fast rm sometimes fails unit tests about b2_command_line_tool

[przadka]

@ppolewicz Can you please provide more info on how/where to reproduce it?

I did not manage to reproduce it on my machine, maybe I am doing something wrong. I wrote a simple bash script to run the test 100 times, but not a single run failed. I only run test_rm_fail_fast in isolation, not the full suite.

For reference, here is the script:

#!/bin/bash

# Set failure counter
failures=0

# Repeat the test 100 times
for i in {1..100}
do
    echo "Run $i"
    # Run the test and check if it fails
    nox -s unit-3.10 -- -k test_rm_fail_fast
    if [ $? -ne 0 ]; then
        ((failures++))
    fi
done

# Output the number of failures
echo "Failures: $failures"
