papi: add wrapper to validate crc manifest
If a client application is built against 19.08, it can dump the "manifest" of API signatures. Either the all APIs (--dump) or the APIs it is interested in (--dumpfiltered). When the developers of said client application wants to verify that it works with VPP 20.01. It can connect to VPP and --validate the old mainfest file, and will be told a list of messages (both request and reply) that has changed. import argparse from vpp_papi import VPP import sys import argparse parser = argparse.ArgumentParser() group = parser.add_mutually_exclusive_group() group.add_argument("--dump", action="store_true") group.add_argument("--dumpfiltered", action="store_true") group.add_argument("--validate", action="store_true") args = parser.parse_args() vpp = VPP(use_socket=True) vpp.connect(name='apimanifest') if args.validate: # Verify manifest message_table = eval(sys.stdin.read()) missing = vpp.validate_message_table(message_table) print ('Changed message signatures: {}'.format(missing)) elif args.dump: # Output manifest to stdout print('{}'.format(vpp.dump_message_table())) elif args.dumpfiltered: # Output manifest to stdout filterlist = eval(sys.stdin.read()) print('{}'.format(vpp.dump_message_table_filtered(filterlist))) vpp.disconnect() Type: feature Change-Id: I7e708b36f599ed88e4864970c8593cc2fe5fbf61 Signed-off-by: Ole Troan <ot@cisco.com>
