2018-02-17vpp_papi: remove legacy way of calling VPP APIsKlement Sekera1-7/+0
This allows VPP to define APIs which conflict with internal function names used in vpp_papi without issues. Change-Id: I56c21814e1c11fa2aa6bcd95adb3fdeacd304e8e Signed-off-by: Klement Sekera <ksekera@cisco.com>
2018-02-17vpp_papi: reduce memory leaksKlement Sekera1-12/+16
This changes makes unused VPP objects collectable by garbage collector, allowing running all `make test` tests again instead of python crashing due to running out of memory. Change-Id: I0e271c2b3f195d9d3b64840f9f11144da0fe967d Signed-off-by: Klement Sekera <ksekera@cisco.com>

2017-11-20Have PAPI find its API definition filesChris Luke1-5/+140
- Add a basic heuristic to have vpp_papi search in several places for the JSON API files. - It's clever enough to work out the path to these files from within several places in the source tree, falling back to the system location as a last resort.

2017-10-31VPP PAPI: Error in unserializer for non-array compound types.Ole Troan1-0/+1
A bug in the decoder of messages when there was a non-array compound type. The typical result was an error message from the struct library: "error:unpack_from requires a buffer of at least 4 bytes" Change-Id: Ie30fec6fc39b9f4177b54fa4adc4fc69674f0e12 Signed-off-by: Ole Troan <ot@cisco.com>

2017-03-03python API: work towards python/vpp api separationKlement Sekera1-1/+30
This change improves vpp_papi behaviour by introducing alternate way of calling vpp APIs. The common code is the same: vpp = VPP(...) vpp.connect(...) Calling VPP API is different, instead of deprecated: vpp.show_version() # deprecated one should write vpp.api.show_version() this allows VPP messages like "connect" and "disconnect" to be used, once the old API is dropped (in 17.07). Also part of this patch is a check for name conflict, to prevent VPP object overwriting its own functionality with generated code based on json files.

2017-01-27Python API: event_callback not initialised.Ole Troan1-0/+1
Even when not requesting notification the VPP API sends event notifications on certain calls. E.g. creating interfaces. Traceback (most recent call last): File "/vpp/ipfix/src/vpp-api/python/vpp_papi/vpp_papi.py", line 447, in msg_handler_sync if self.event_callback: AttributeError: VPP instance has no attribute 'event_callback' Change-Id: I4ca30c49df298655dc8948c5ebd68de0b3d6a592 Signed-off-by: Ole Troan <ot@cisco.com>
2017-01-26Change automake python macro to get python pathTomofumi Hayashi1-1/+2
Previously install path for python binding is fixed, as lib/python2.7/site-packages and other version/enironement is not supported. This change introduces automake's python macro and gets the install path from environment dynamically.

2017-01-20Python API: Missing locking of results data structure.Ole Troan1-84/+219
The wrong assumption that the GIL combined with CPython's "mostly" thread safe assurance does not hold. The combination of a slow event handler for notification and calling the API at the same time let to contention on the results data structure. Added suitable locking. Also added an atexit() to attempt a VPP disconnect on shutdown. Also: lots more comments, docstrings, duplicated code removed. Some of the problem here was a disagreement between caller and author as to how the API should be used; the comments should help.
