Enable passing a custom timeout value to run_all.py. If unspecified, the default remains 180. Tested: on kernel netdev-netnext/master HEAD at commit 5e437416ff669 (1) verify default timeout remains 180: $ python ./packetdrill/run_all.py -S -v -L -l tcp/mss/mss-getsockopt-tcp_maxseg-server.pkt OK [/export/hda3/tmp/tannerlove/net/tcp/mss/mss-getsockopt-tcp_maxseg-server.pkt (ipv4)] stdout: stderr: OK [/export/hda3/tmp/tannerlove/net/tcp/mss/mss-getsockopt-tcp_maxseg-server.pkt (ipv6)] stdout: stderr: OK [/export/hda3/tmp/tannerlove/net/tcp/mss/mss-getsockopt-tcp_maxseg-server.pkt (ipv4-mapped-v6)] stdout: stderr: Ran 3 tests: 3 passing, 0 failing, 0 timed out (3.83 sec): tcp/mss/mss-getsockopt-tcp_maxseg-server.pkt (2) verify -t 0 results in timeout: python ./packetdrill/run_all.py -S -v -L -l -t 0 tcp/mss/mss-getsockopt-tcp_maxseg-server.pkt KILL [/export/hda3/tmp/tannerlove/net/tcp/mss/mss-getsockopt-tcp_maxseg-server.pkt (ipv4)] stdout: stderr: KILL [/export/hda3/tmp/tannerlove/net/tcp/mss/mss-getsockopt-tcp_maxseg-server.pkt (ipv4-mapped-v6)] stdout: stderr: KILL [/export/hda3/tmp/tannerlove/net/tcp/mss/mss-getsockopt-tcp_maxseg-server.pkt (ipv6)] stdout: stderr: Ran 3 tests: 0 passing, 0 failing, 3 timed out (1.85 sec): tcp/mss/mss-getsockopt-tcp_maxseg-server.pkt Signed-off-by: Tanner Love <tannerlove@google.com>
When flag is specified, run_all.py does not look for .pkt files in subdirectories of the specified directory. Tested: (on kernel netdev-netnext/master HEAD at commit 5e437416ff669) Currently there are no existing cases where we have both a foo/bar.pkt and a foo/baz/buz.pkt. To simulate this likely future scenario, I did: (0) setup: duplicate a test in a parent dir $ cp gtests/net/tcp/fastopen/server/client-ack-dropped-then-recovery-ms-timestamps.pkt \ gtests/net/tcp/fastopen/client-ack-dropped-then-recovery-ms-timestamps.pkt (1) verify that subdirs are traversed when flag is not specified $ python ./packetdrill/run_all.py -S -v -L -l tcp/fastopen OK [/export/hda3/tmp/tannerlove/net/tcp/fastopen/client-ack-dropped-then-recovery-ms-timestamps.pkt (ipv4)] stdout: stderr: OK [/export/hda3/tmp/tannerlove/net/tcp/fastopen/client-ack-dropped-then-recovery-ms-timestamps.pkt (ipv6)] stdout: stderr: OK [/export/hda3/tmp/tannerlove/net/tcp/fastopen/server/client-ack-dropped-then-recovery-ms-timestamps.pkt (ipv4-mapped-v6)] stdout: stderr: OK [/export/hda3/tmp/tannerlove/net/tcp/fastopen/client-ack-dropped-then-recovery-ms-timestamps.pkt (ipv4-mapped-v6)] stdout: stderr: OK [/export/hda3/tmp/tannerlove/net/tcp/fastopen/server/client-ack-dropped-then-recovery-ms-timestamps.pkt (ipv6)] stdout: stderr: OK [/export/hda3/tmp/tannerlove/net/tcp/fastopen/server/client-ack-dropped-then-recovery-ms-timestamps.pkt (ipv4)] stdout: stderr: Ran 6 tests: 6 passing, 0 failing, 0 timed out (4.32 sec): tcp/fastopen (2) verify that subdirs are not traversed when flag is specified $ python ./packetdrill/run_all.py -S -v -L -l --no-traverse_subdirs tcp/fastopen OK [/export/hda3/tmp/tannerlove/net/tcp/fastopen/client-ack-dropped-then-recovery-ms-timestamps.pkt (ipv4)] stdout: stderr: OK [/export/hda3/tmp/tannerlove/net/tcp/fastopen/client-ack-dropped-then-recovery-ms-timestamps.pkt (ipv6)] stdout: stderr: OK [/export/hda3/tmp/tannerlove/net/tcp/fastopen/client-ack-dropped-then-recovery-ms-timestamps.pkt (ipv4-mapped-v6)] stdout: stderr: Ran 3 tests: 3 passing, 0 failing, 0 timed out (2.64 sec): tcp/fastopen Signed-off-by: Tanner Love <tannerlove@google.com>
