This functionality is used in make test when DEBUG=gdb is used. Type: fix Signed-off-by: Klement Sekera <ksekera@cisco.com> Change-Id: I1339e6460aa624a3bcb4b03db46991590e126f92

2020-12-03papi: allow client control over loggersPaul Vinciguerra1-0/+3
This change enables a client to set debug levels globally as well as individually. exposes loggers as vpp_papi vpp_papi.serializer vpp_papi.transport Type: improvement Change-Id: Ib6bd1a1f552b51a22c9fe3de819a5fb970963ae5 Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>
2019-12-03papi: add a per-call _timeout optionPaul Vinciguerra1-2/+4
add the ability to override the default timeout value on a per-call basis. Use: rv = self.vapi.papi.cli_inband(cmd='wait 10', _timeout=15) Type: feature Change-Id: Ia90a58586a1f63e02118599a2a4b7141e5a0b90d Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>
2019-10-14papi: fix socket sendall callsVratko Polak1-4/+6
No point in checking the return value, as .sendall() raises on error (and the previous check was missing "not"). Type: fix Change-Id: I9e07709ddd7093f91ffef87808abbab264b8aa5a Signed-off-by: Vratko Polak <vrpolak@cisco.com>
2019-10-11papi: 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. Type: fix Change-Id: Iae1a68bf8f9e666856b7c7d62ebfe22defc5dfe1 Signed-off-by: Vratko Polak <vrpolak@cisco.com>

2019-06-26papi: prevent message_table inconsistenciesVratko Polak1-0/+2
Socket transport is maintaining message_table to map message name to index. After disconnect and re-connect, the VPP may have been restarted with different set of plugins, so message_table has to be wiped. + Edited MAINTAINERS to recognize "papi" as a separate component. Type: fix Change-Id: I1f16ad7ee0886e03bbc6a17bcddbfcaa322354e5 Signed-off-by: Vratko Polak <vrpolak@cisco.com>

2019-06-12papi: make socket disconnect more robustVratko Polak1-1/+1
Previusly, read error could happen before message_thread starts, so do not attempt to join in that case. Change-Id: Ie119916831e320e38eb02e48515b4c6a9cb937e5 Signed-off-by: Vratko Polak <vrpolak@cisco.com>
2019-06-07API: Add support for "defaults"Ole Troan1-6/+6
Add support in the API language for specifying a field default. Add default support in Python binding. define foo { u16 mtu [default = 1500]; }; This is client side only. I.e. if the mtu argument is not passed to the foo function, the client language binding will set it default to 1500.

2019-05-10vpp_transport_socket: make connect more resilientVratko Polak1-11/+32
This should make connect() partially retriable, at least against "No such file or directory on socket", and when disconnect() is called before retrying connect(). Added TODOs for future improvements. Change-Id: I5ee727fbc17d66446589b8c781f270055187db68 Signed-off-by: Vratko Polak <vrpolak@cisco.com>

2019-05-07Allow repeated connects on PAPI socket transportVratko Polak1-1/+10
The previous implementation fails with RuntimeError("cannot set daemon status of active thread") when a second connect() follows first disconnect(). Change-Id: I671005923eb020130a57b0b484a3386a05d7be33 Signed-off-by: Vratko Polak <vrpolak@cisco.com>
2019-04-23API: Python and Unix domain socket improvementOle Troan1-27/+19
Handle the case where buffer overflows. Then SOCK_SEQPACKET assumption that multiple API messages are not returned by recv() is broken. Use SOCK_STREAM for API exchanges instead. Add support for running tests over sockets. make test SOCKET=1 Change-Id: Ibe5fd69b1bf617de4c7ba6cce0a7c2b3f97a2821 Signed-off-by: Ole Troan <ot@cisco.com>
2018-12-13API: Use string type instead of u8.Ole Troan1-2/+1
The new string type is modelled after string in proto3. It is always variable length. Change-Id: I64884067e28a80072c8dac31b7c7c82d6e306051 Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Michal Cmarada <mcmarada@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com>

2018-11-29vpp_papi: Fix: raise NotImplemented.Paul Vinciguerra1-1/+1
'raise NotImplemented' should be 'raise NotImplementedError'. NotImplemented is not part of the Exception heirarchy. Change-Id: I7fb647f1d56e689fafa2cd9a5566da826def072b Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>
