* [PATCH] app/testpmd: fix auto completion for indirect list action @ 2024-03-18 9:21 Shani Peretz 2024-03-19 14:51 ` Ferruh Yigit 0 siblings, 1 reply; 8+ messages in thread From: Shani Peretz @ 2024-03-18 9:21 UTC (permalink / raw) To: dev Cc: shperetz, mkashani, Ori Kam, Aman Singh, Yuying Zhang, Gregory Etelson In the process of auto completion of a command in testpmd, the parser splits the command into tokens, where each token represents an argument and defines a parsing function. The parsing function of the indirect_list action argument was returning before having the opportunity to handle the argument. The fix ensures that the function appropriately handles the argument before finishing.

What is the status of incorporating this feature into dts? But I guess it won't catch this issue, as it uses full flow commands. This issue is related to the testpmd command parsing code.

A similar idea has been proposed for DTS. I believe the plan is at the end of 2024 techboard is going to discuss adding this as a requirement for patches affecting certain components in DPDK. So a change related to the new feature must come with an accompanied /dts testsuite addition at the same time. > > > > > > Thanks Gregory, I missed this proposal, we need something to verify flow > APIs, so +1 to the effort. > What is the status of incorporating this feature into dts? The DTS 24.07 roadmap does not include testsuites verifying flow APIs, but if work proceeds at a good pace and there is space for it, we can look at writing something for 24.07. Otherwise it falls to 24.11 or 25.03.

I wonder if > we can find a way to verify testpmd parsing code? What if flow command validation program breaks a tested command into tokens and then pass each token followed by the TAB key to the controlled testpmd process ? There are 3 possible outputs for the token + TAB sequence: 1. a valid token will trigger meaningful testpmd help ouput that can be matched. 2. invalid token output will fail [1]. 3. invalid token will crash the controlled testpmd process. I've compiled a small programm to test that idea. Please check it out.
