2020-02-18papi: harden socket handlingVratko Polak1-18/+24
In the previous implementation of socket transport for PAPI, socket methods .send and .recv_into were used. But they are not guaranteed to send/receive all the data for the full message. The receive part contained a loop, but it handled only the main message, not the header. This patch replaces .send with .sendall and uses newly defined _read_fixed method. Also, removed Paul from maintainers, as he is not active much, lately.

2020-02-18papi: introduce read_blockingVratko Polak1-3/+29
Previously, self.transport.q got the messages (at least for socket transport), stored in the encoded (packed) form. In order to avoid accessing internals for async reads, a new method is introduced, to perform blocking reads of decoded (unpacked) messages. The method is also used in _call_vpp(), so sync and async reads are kept compatible.

2019-09-09api: enforce vla is last and fixed string typeOle Troan2-16/+70
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 <ot@cisco.com> (cherry picked from commit e5ff5a36dd126ee57dca4e0b03da2f7704e0a4f5) Signed-off-by: Ole Troan <ot@cisco.com>

2019-07-31api papi: add alias for timestamp(datetime)/timedeltaPaul Vinciguerra1-1/+8
Now that we have support for f64: - create explicit types for timestamp(datetime)/timedelta - update log_details to use timestamp and remove redundant string representation. If you need the string representation, in python do str(timestamp). If you prefer the raw f64 value, the client can pass in the _no_type_conversion option.

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.

This is the first step to be able to remove all the API message wrappers in vpp_papi_provider.py.

Note when removing functions, the calls in vpp_papi_provider wrappers do not necessarily follow message order.
