From 30d28bdfd8aca4d6d3c70482ad9ebfdb753610aa Mon Sep 17 00:00:00 2001 From: Ole Troan Date: Fri, 23 Aug 2019 22:55:18 +0200 Subject: api: enforce vla is last and fixed string type Enforce that variable length fields are the last element of API messages. Add a 'fixed' version of string type, since dealing with multiple variable length strings turned out too painful for the C language bindings. The string type is now: { string name[64]; // NUL terminated C-string. Essentially decays to u8 name[64] string name[]; // Variable length string with embedded len field (vl_api_string_t) }; The latter notation could be made available to other types as well. e.g. { vl_api_address_t addresses[]; } instead of { u32 n_addr; vl_api_address_t addresses[n_addr]; }; Type: fix Change-Id: I18fa17ef47227633752ab50453e8d20a652a9f9b Signed-off-by: Ole Troan (cherry picked from commit e5ff5a36dd126ee57dca4e0b03da2f7704e0a4f5) Signed-off-by: Ole Troan --- test/ext/vapi_c_test.c | 13 ++++--------- test/ext/vapi_cpp_test.cpp | 7 ++----- 2 files changed, 6 insertions(+), 14 deletions(-) (limited to 'test/ext') diff --git a/test/ext/vapi_c_test.c b/test/ext/vapi_c_test.c index 0b22fff1706..d49f23023dd 100644 --- a/test/ext/vapi_c_test.c +++ b/test/ext/vapi_c_test.c @@ -359,14 +359,11 @@ show_version_cb (vapi_ctx_t ctx, void *caller_ctx, { ck_assert_int_eq (VAPI_OK, rv); ck_assert_int_eq (true, is_last); - ck_assert_str_eq ("vpe", (char *) vl_api_from_api_string (&p->program)); + ck_assert_str_eq ("vpe", (char *) p->program); printf ("show_version_reply: program: `%s', version: `%s', build directory: " - "`%s', build date: `%s'\n", - vl_api_from_api_string (&p->program), - vl_api_from_api_string (&p->version), - vl_api_from_api_string (&p->build_directory), - vl_api_from_api_string (&p->build_date)); + "`%s', build date: `%s'\n", p->program, p->version, p->build_directory, + p->build_date); ++*(int *) caller_ctx; return VAPI_OK; } @@ -802,9 +799,7 @@ generic_cb (vapi_ctx_t ctx, void *callback_ctx, vapi_msg_id_t id, void *msg) ck_assert_int_eq (id, vapi_msg_id_show_version_reply); ck_assert_ptr_ne (NULL, msg); vapi_msg_show_version_reply *reply = msg; - ck_assert_str_eq ("vpe", - (char *) vl_api_from_api_string (&reply-> - payload.program)); + ck_assert_str_eq ("vpe", (char *) reply->payload.program); return VAPI_OK; } diff --git a/test/ext/vapi_cpp_test.cpp b/test/ext/vapi_cpp_test.cpp index 68366af2ac8..2c2a82c8a9d 100644 --- a/test/ext/vapi_cpp_test.cpp +++ b/test/ext/vapi_cpp_test.cpp @@ -49,11 +49,8 @@ void verify_show_version_reply (const Show_version_reply &r) auto &p = r.get_payload (); printf ("show_version_reply: program: `%s', version: `%s', build directory: " "`%s', build date: `%s'\n", - vl_api_from_api_string (&p.program), - vl_api_from_api_string (&p.version), - vl_api_from_api_string (&p.build_directory), - vl_api_from_api_string (&p.build_date)); - ck_assert_str_eq ("vpe", (char *)vl_api_from_api_string (&p.program)); + p.program, p.version, p.build_directory, p.build_date); + ck_assert_str_eq ("vpe", (char *)p.program); } Connection con; -- cgit 1.2.3-korg
