2019-07-24vapi: add python scripts to vpp-dev packageVratko Polak1-7/+19
As requested in https://lists.fd.io/g/vpp-api-dev/message/18 three vapi scrips are packaged, destination to share/vpp/. Also: + Add "vapi" as a separate component to maintainers file. + Add also vppapigen/generate_json.py to share/vpp/. + Improve CMakeLists.txt indentation.

2019-07-24papi: add additional types to vpp_serializerPaul Vinciguerra1-0/+3
vppapigen supports additional types not handled by the papi seializer. This adds the types for the sake of parity. Change-Id: Id8efad7f169b5023879935575ace2cc3e9c291d4 Type: feature Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>
2019-07-16papi: use the injected logger wherever possibleVratko Polak1-18/+6
As the injected logger is already expected to be used everywhere, this is a fix. The few lines in vpp_serializer.py are not fixed, but they are not encountered in CSIT testing. Functions call_logger and return_logger have single call site each (and confusing names, as they do not log), so saved few lines by inlining them.

2019-07-08map gbp papi: match endianess of f64Paul Vinciguerra1-1/+1
clib_net_to_host_f64, clib_host_to_net_f64 are now implemented as '=', https://gerrit.fd.io/r/#/c/20406/ set papi to match. - all f64 api references are now wrapped with clib_net_to_host_f64 or clib_host_to_net_f64. IEEE f64 endianess is not defined. If clib_net_to_host_f64 and clib_host_to_net_f64 are later defined in VPP as big-endian, it is a single character change in the papi vpp_serializer. Note: This breaks the api in a manner that would not be detected by the flag day initiative. The scope is small. This only impacts map.api, which applied the u64 transformation, while the gbp api uses '='. The implementation of "=" raises issues for the papi socket implementation if used between systems of differing endianess. See Vratko's comments. - Added get_f64_endian_value() to api to allow client to verify endianess of f64's.
