Run aggregations against a multi-threaded target program and validate that the results are correct. Work in progress. - I haven't worked out how to use signed integers for min/max aggregations...
This script should print "true": ``` BEGIN { @[1] = 1; @[2] = 2; $count = len(@); // Uncomment this line and it works //$count = 2; printf("count: %d\n", $count);...
Run `./build/tests/bpftrace_test`, leave it to run for a few seconds and then try pressing Ctrl-C. The tests won't terminate and will run to completion. It is only a subset of...

In #2203, a signal handler for SIGUSR1 was added, which prints all maps when the signal is received. Note: it appears that the docs for this feature have been deleted...
