Suspected cause: multicasting not working for nodes with an interface 0 due to lack of 'mirroring_add 0 0' line in hp4commands.txt

And it is super awesome One thing left for VIBRANT support - modify_field_rng_uniform Should be a can of cake

Unfortunately, remove_header is broken. But add_header works and it is awesome.

ISSUES.md can track all known issues, starting with the fact that parse_ctrl.state should be a match parameter in match.p4t tables, as a ternary match since it won't be needed all the time.

We've applied a fix to p4_hp4 but are not yet sure it is correct in all cases; test_select.txt includes some p4_hp4 data structures to look at following generation of tset_pipeline_config entries

Current codebase supports the following configurations, where the first number is the number of stages supported, and the second number is the max number of primitives per stage supported: - 2 x 9 - 3 x 8 - 4 x 5 - 5 x 4 - 6 x 3 - 8 x 2 - 9 x 1 ...as well as any configuration smaller in at least one dimension than one of the listed configurations.

Number of actions does not change with hp4's configuration in terms of the number of stages and primitives supported. The total number of actions is currently 150 and only changes as we modify P4 support. This number is well under Agilio's limit of 256 actions.

Generates all hp4 configurations 1-X by 1-Y, where X is the number of stages supported, and Y is the max number of primitives per stage supported. Then counts the total number of actions defined per configuration, and collects results across all configurations into a .csv.

The test reveals that p4_hp4 does not properly handle this type of parser return statement yet; ongoing analysis is in tests/analysis/test_select.txt.

Unwanted output noted in previous commit was result of forgetting that the hp4controller modules had been installed to /usr/local/... via setuptools (setup.py in hp4-ctrl), so the modules being accessed were not the ones I was modifying in my home directory. To more easily modify these files and run tests, instead of using setuptools we modify PYTHONPATH in .profile in the home directory. We must also modify sudoers to preserve the environment when running commands via sudo, because the test requires the use of sudo, because of mininet. We should add basic instructions to this effect.

Demo: HP4 running test_hub; two tests: - h1 ping h2 (expected: success) - h1 ping h3 (expected: fail) Both tests return the expected results. To run: sudo ./test.py. Additional tests may be added with 1-3 files per need: - <proj>.p4 - [<proj>.commands] -- bmv2 runtime table management commands - [<proj>.py] -- test cases + mininet script If the <proj>.py file is not present, the framework uses test_mininet.py with the two tests described above (h1 ping h2, h1 ping h3).

Action handling now involves checking whether meta_primitive_state.primitive[+Y+] == 0 between primitives, which indicates no further primitives remain, but that value was used to indicate a modify_field primitive, so the value for modify_field has been changed.

This folder housed old tests that have long since been rendered obsolete by 1) changes to HyPer4; and 2) the controller repository (hp4-ctrl: git@gitlab.flux.utah.edu:hp4/hp4-ctrl.git). Saved two analysis scripts that may yet be useful in hp4/analysis.
