From 33a58171e5995d9e649b414bfc77f2aab26e4c58 Mon Sep 17 00:00:00 2001 From: Ole Troan Date: Wed, 4 Sep 2019 09:12:29 +0200 Subject: api: autogenerate api trace print/endian In addition to the external vppapitrace tool, VPP itself supports dumping of API trace files. In two formats, "custom-dump" and "dump". "dump" gives a human friendly list, and "custom-dump" is meant to give a list of commands that can be fed to VAT. This patch only deals with "dump". Prior to this fix, auto-generation was only done for the basic types. This fix adds support for any type, including lists, and supports pretty-printing of enums, strings, IP addresses, MAC addresses and so on. Usage: api trace dump For example Change-Id: I4e485680e6dcfce7489299ae6cf31d835071ac40 ---------- trace 48 ----------- vl_api_sw_interface_set_flags_t: _vl_msg_id: 75 client_index: 0 context: 10 sw_if_index: 1 flags: IF_STATUS_API_FLAG_ADMIN_UP ---------- trace 49 ----------- vl_api_sw_interface_add_del_address_t: _vl_msg_id: 88 client_index: 0 context: 11 sw_if_index: 1 is_add: 1 del_all: 0 prefix: 172.16.1.1/24 ---------- trace 51 ----------- vl_api_cli_inband_t: _vl_msg_id: 819 client_index: 0 context: 13 cmd: packet-generator capture pg0 pcap /tmp/vpp-unittest-TestMAP-YhcmDX/pg0_out.pcap disable ---------- trace 58 ----------- vl_api_ip_neighbor_add_del_t: _vl_msg_id: 199 client_index: 0 context: 20 is_add: 1 neighbor: sw_if_index: 2 flags: IP_API_NEIGHBOR_FLAG_NONE mac_address: 0202.0000.ff02 ip_address: fd01:2::2 Signed-off-by: Ole Troan Change-Id: I5556d06008de2762e7c2d35a8b0963ae670b3db1 Type: fix Signed-off-by: Ole Troan Signed-off-by: Ole Troan Signed-off-by: Ole Troan Signed-off-by: Ole Troan Signed-off-by: Ole Troan Signed-off-by: Ole Troan Signed-off-by: Ole Troan Signed-off-by: Ole Troan --- src/tools/vppapitrace/vppapitrace.py | 11 ++++++----- 1 file changed, 6 insertions(+), 5 deletions(-) (limited to 'src/tools/vppapitrace') diff --git a/src/tools/vppapitrace/vppapitrace.py b/src/tools/vppapitrace/vppapitrace.py index 640b820d994..8089b3a2236 100755 --- a/src/tools/vppapitrace/vppapitrace.py +++ b/src/tools/vppapitrace/vppapitrace.py @@ -102,6 +102,7 @@ def unserialize_msgtbl(data, offset): def serialize_msgtbl(messages): offset = 0 + # XXX 100K? data = bytearray(100000) nmsg = len(messages) data = struct.pack(">I", nmsg) @@ -380,8 +381,8 @@ def generate(args): filename, file_extension = os.path.splitext(args.input) input_type = JSON if file_extension == '.json' else APITRACE - filename, file_extension = os.path.splitext(args.output) + if args.todump: output_type = DUMP else: @@ -395,7 +396,7 @@ def generate(args): if input_type == output_type: sys.exit("error: Nothing to convert between") - if input_type == JSON and output_type == APITRACE: + if input_type != JSON and output_type == APITRACE: sys.exit("error: Input file must be JSON file: {}".format(args.input)) messages, services = init_api(args.apidir) @@ -407,11 +408,11 @@ def generate(args): i += 1 n, result = json2apitrace(messages, args.input) + msgtbl = serialize_msgtbl(messages) + print('API messages: {}'.format(n)) - header = struct.pack(">IIB", n, len(messages), 0) + header = struct.pack(">IIB", n, len(msgtbl), 0) - i = 0 - msgtbl = serialize_msgtbl(messages) with open(args.output, 'wb') as outfile: outfile.write(header) outfile.write(msgtbl) -- cgit 1.2.3-korg
