There's no reason to parse "http_status_line"; the PHP interpreter already
does this. If the line contains a valid status code, it's assigned to
"http_response_code".
This also fixes invalid status line handling, where the nxt_int_parse()
function returned -1; it was cast to unsigned, yielding response code 65535.
Added the following command line arguments:
-d, --detailed: Show detailed output for tests
Usage examples:
./test/run.py --detailed
python3 test/test_access_log.py --detailed
python3 test/test_access_log.py -d TestUnitAccessLog.test_access_log_ipv6
-l, --log: Save unit.log after the test execution
Usage examples:
./test/run.py -l
python3 test/test_access_log.py -l
python3 test/test_access_log.py --log TestUnitAccessLog.test_access_log_ipv6
