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>
2018-11-29API: Add support for type aliasesOle Troan2-3/+22
Previously all types are compound. This adds support for aliases, so one can do things like: typedef u32 interface_index; or typedef u8 ip4_address[4]; Change-Id: I0455cad0123fc88acb491d2a3ea2725426bdb246 Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Klement Sekera <ksekera@cisco.com>

2018-11-28vpp_papi: Use new style classes.Paul Vinciguerra6-13/+13

2018-10-22PAPI: Add support for format/unformat functions.Ole Troan5-12/+247
With the introduction of new types, like vl_api_address_t it is now possible to call a message using one of those functions with a string representation. E.g. for an IP address ip_add_address(address="1.1.1.1/24") The language wrapper will automatically convert the string into the vl_api_address_t representation. Currently the caller must do the reverse conversion from the returned named tuple with the unformat function. rv = get_address_on_interface(sw_if_index=1) print(VPPFormat.unformat(rv.address)) Change-Id: Ic872b4560b2f4836255bd5260289bfa38c75bc5d Signed-off-by: Ole Troan <ot@cisco.com>

The implementation of parallel test execution in VPP Test Framework. - VPPTestCase test methods are grouped together - tests are running in separate processes - VPP instances spawned by tests are assigned to different cores - output from these processes is redirected through pipes and printed out testcase by testcase - TEST_JOBS env var is used to specify the number of parallel processes - improved test summary - a bit of code cleanup Change-Id: I9ca93904d9fe2c3daf980500c64a8611838ae28c Signed-off-by: juraj.linkes <juraj.linkes@pantheon.tech>

2018-06-06Alter logging semantics for VPP PAPI objectIan Wells1-2/+11
Logging previously used a string name for the log level and changed the system-wide log level based on this string name. It now uses a logging-module provided constant for the log level and changes its own logger's level based on the name, and only if the level is provided. This allows the logging to be more compatible with Pythonic usage, where an external source may be used to dictate logging levels across the system on a per module basis and should not be overridden.
