New submission from Arfrever Frehtes Taifersar Arahesis:
Function runtest() (used by single-process mode) always returns tuple with test
result as integer and test time as float.
This tuple is passed as second argument to function accumulate_result(), which
has (in Python 3.6):
def accumulate_result(self, test, result):
ok, test_time = result
self.test_times.append((test_time, test))
test_times is later used by code, which expects that times are floats:
if self.ns.print_slow:
self.test_times.sort(reverse=True)
print("10 slowest tests:")
for time, test in self.test_times[:10]:
print("%s: %.1fs" % (test, time))
Code used by multi-process mode can return tuple with integer and string
(describing error in subprocess), which with --slow option would cause
TypeError.
Example:
In terminal 1:
$ LD_LIBRARY_PATH="$(pwd)" ./python -m test.regrtest -j2 --slow test_lib2to3
In terminal 2 (sufficiently quickly):
$ kill -SIGINT $(ps aux | grep '"test_lib2to3"' | grep -v grep | awk '{print
$2}')
Output in terminal 1:
Test suite interrupted by signal SIGINT.
1 test omitted:
test_lib2to3
10 slowest tests:

print("%s: %.1fs" % (test, time))
TypeError: a float is required
My suggested fix is to return string describing error as third element of that
tuple.
