18 A1 Mediator Release Notes
19 =========================
21 All notable changes to this project will be documented in this file.
23 The format is based on `Keep a Changelog <http://keepachangelog.com/>`__
24 and this project adheres to `Semantic Versioning <http://semver.org/>`__.
30 * Release 1.0.0 will be the Release A version of A1
37 * This is on the road to release 1.0.0. It is not meant to be tested (E2E) as it's own release
38 * Implement the Release A spec in the openapi.yaml
39 * Rework A1 to follow that spec
40 * Remove rmr_mapping now that we use policyid as the mtype to send and a well known mtype for the ACKs
41 * Add the delay receiver test to the tavern integration tests
42 * Remove unneeded ENV variables from helm charts
43 * Switch away from builder images to avoid quicksand; upgrade rmr at our own pace
50 * Update to later rmr-python
51 * Add docs about upgrading rmr
52 * remove bombarder since tavern runs apache bench
59 * Update to later rmr-python
65 * Greatly reduce the size of A1 docker from 1.25GB to ~278MB.
66 * Add a seperate dockerfile for unit testing
73 * Rename all /ric/ URLs to be consistent with requirements of /a1-p/
81 * Implement the GET on policies
82 * Add a new endpoint for healthcheck. NOTE, it has been decided by oran architecture documents that this policy interface should be named a1-p in all URLS. In a future release the existing URLs will be renamed (existing URLs were not changed in this release).
90 * Fix the 400, which was in the API, but wasn't actually implemented
91 * Update the test fixture manifests to reflect the latest adm control, paves way for next feature coming which is a policy GET
100 * Use base Docker with NNG version 1.1.1
109 * Upgrade RMR due to a bug that was preventing rmr from init in kubernetes
118 * Run unit tests as part of docker build
127 * Convert docs to appropriate format
128 * Move rmr string to int mapping to a file
137 * Use tavern to test the actual running docker container
138 * Restructures the integration tests to run as a single tox command
139 * Re-ogranizes the README and splits out the Developers guide, which is not needed by users.
148 * Adds a defense mechanism against A1 getting queue-overflowed with messages A1 doesnt care about; A1 now ignores all incoming messages it's not waiting for, so it's queue size should now always be "tiny", i.e., never exceeding the number of valid requests it's waiting for ACKs back for
149 * Adds a test "bombarding" script that tests this
158 * Main purpose of this change is to fix a potential race condition where A1 sends out M1 expecting ACK1, and while waiting for ACK1, sends out M2 expecting ACK2, but gets back ACK2, ACK1. Prior to this change, A1 may have eaten ACK2 and never fufilled the ACK1 request.
159 * Fix a bug in the unit tests (found using a fresh container with no RIC manifest!)
160 * Fix a (critical) bug in a1rmr due to a rename in the last iteration (RMR_ERR_RMR_RCV_RETRY_INTERVAL)
161 * Make unit tests faster by setting envs in tox
162 * Move to the now publically available rmr-python
163 * Return a 400 if am xapp does not expect a body, but the PUT provides one
164 * Adds a new test policy to the example RIC manifest and a new delayed receiver to test the aformentiond race condition
173 * Upgrade to rmr 0.10.0
174 * Fix bad api spec RE GET
175 * Fix a (big) bug where transactionid wasn't being checked, which wouldn't have worked on sending two policies to the same downstream policy handler
184 * Rip some testing structures out of here that should have been in rmr (those are now in rmr 0.9.0, upgrade to that)
185 * Run Python BLACK for formatting
194 * Fix a blocking execution bug by moving from rmr's timeout to a non blocking call + retry loop + asyncronous sleep
195 * Changes the ENV RMR_RCV_TIMEOUT to RMR_RCV_RETRY_INTERVAL
204 * Update to rmr 0.8.3
205 * Change 503 to 504 for the case where downstream does not reply, per recommendation
206 * Add a 502 with different reasons if the xapp replies but with a bad/malformed/missing status
207 * Make testing much more modular, in anticipating of moving some unit test functionality into rmr itself
216 * Crash immediately if manifest isn't mounted
217 * Add unit tests for utils
227 * Upgrade A1 to rmr 0.8.0
228 * Go from deb RMR installation to git
229 * Remove obnoxious receiver logging
238 * Upgrade A1 to rmr 0.6.0
247 * Add license headers
256 * Introduce RIC Manifest
257 * Move some testing functionality into a helper module
258 * Read the policyname to rmr type mapping from manifest
259 * Do PUT payload validation based on the manifest
268 * Bump rmr python dep version
269 * Include a Dockerized test receiver
270 * Stencil out the mising GET
272 * Include a test docker compose file
281 * Initial Implementation
