Re: [vpp-dev] vpp api versioning

Hello folks, I've just sent 3 patches addressing issues in LCP [0] [1] [2]. First one for marking APIs in progress. 2nd only for s/namespace/netns/g. 3rd fixes endian issues in different methods. One thing I can't understand - if the "autoendian" keyword is specified for API type - I should use ma

Re: [vpp-dev] vpp api versioning

Hi Matt, Oh right, so especially given the plugin is marked experimental, in-place approach would make a lot of sense… By saying “experimental” I was thinking of marking the API messages as “in-progress” [0] - which would then exempt them from the change enforcements and allow further iteratio

Re: [vpp-dev] vpp api versioning

Hi Andrew, Neale and I are the maintainers of linux-cp. I am ok with changing it in place because the use of "namespace" is preventing Stanislav from even being able to compile his code. When you say "mark the APIs as experimental" are you talking about putting "state: experimental" in the FEATUR

Re: [vpp-dev] vpp api versioning

Hi Andrew, Thanks for the explanation. I'll try to reach maintainers of the lcp plugin and convince them :) Yes, I'm working on an agent for managing vpp through binary api and it's written in C++ - so it breaks the compilation. I have a patch in my local repo for that, but now I'm trying to merge

Re: [vpp-dev] vpp api versioning

Hoi, Currently, linux-cp API doesn't seem to work, at least in Python and GoVPP (see previous threads on this mailinglist with bugreports), lcp_itf_pair_add_del_v2() eventually succeeds but throws an error to the caller. This snippet: r = vpp.api.create_loopback() print(r) host_if_name = "loop

Re: [vpp-dev] vpp api versioning

Hi Stanislav, The api is marked as “Production” so the behavior of checkstyle is there to protect the users (as for the duplication - it is a choice to do it once in VPP or in each and every downstream consumer). As for the pure code exercise - I just did it for the sake of a test, took a grand

Hi Ole, Thank you for this, but it is not enough. I don't mean that to come across ungratefully, but it doesn't fix the problem. We need to also remove backward compatible tags from the enums in the .api files. The need for this arose from the fact that enums and enum flags got mixed together a

Hi Andrew, A couple of questions? Firstly, about unit testing aka make test. This is the salient passage in your guide: "foo_message_v2 is tested in "make test" to the same extent as the foo_message" IMHO "to the same extent" implies everywhere v1 is used v2 should now be used in its place.
