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
35 * Implement instance delete
36 * Moves away from the status vector and now aggregates statuses
37 * Pop through a1s mailbox "3x as often"; on all 3 kinds of instance GET since all such calls want the latest information
38 * Misc cleanups in controller (closures ftw)
39 * Add rmr-version.yaml for CICD jobs
44 * Implement GET all policy type ids
45 * Implement GET all policy instance ids for a policy type
46 * fix a tiny bug in integration test receiver
51 * switch to rmr 1.8.1 to pick up a non blocking variant of rmr that deals with bad routing tables (no hanging connections / blocking calls)
52 * improve test receiver to behave with this setup
53 * add integration test for this case
54 * this also switches past 1.5.x, which included another change that altered the behavior of rts; deal with this with a change to a1s helmchart (env: `RMR_SRC_ID`) that causes the sourceid to be set to a1s service name, which was not needed prior
55 * improve integration tests overall
64 * Read type GET to get schema for instance PUT
65 * Remove Utils (no longer needed)
66 * lots more tests (unit and integration)
72 * This is on the road to release 1.0.0. It is not meant to be tested (E2E) as it's own release
73 * Implement the Release A spec in the openapi.yaml
74 * Rework A1 to follow that spec
75 * Remove rmr_mapping now that we use policyid as the mtype to send and a well known mtype for the ACKs
76 * Add the delay receiver test to the tavern integration tests
77 * Remove unneeded ENV variables from helm charts
78 * Switch away from builder images to avoid quicksand; upgrade rmr at our own pace
85 * Update to later rmr-python
86 * Add docs about upgrading rmr
87 * remove bombarder since tavern runs apache bench
94 * Update to later rmr-python
100 * Greatly reduce the size of A1 docker from 1.25GB to ~278MB.
101 * Add a seperate dockerfile for unit testing
108 * Rename all /ric/ URLs to be consistent with requirements of /a1-p/
116 * Implement the GET on policies
117 * 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).
125 * Fix the 400, which was in the API, but wasn't actually implemented
126 * Update the test fixture manifests to reflect the latest adm control, paves way for next feature coming which is a policy GET
135 * Use base Docker with NNG version 1.1.1
144 * Upgrade RMR due to a bug that was preventing rmr from init in kubernetes
153 * Run unit tests as part of docker build
162 * Convert docs to appropriate format
163 * Move rmr string to int mapping to a file
172 * Use tavern to test the actual running docker container
173 * Restructures the integration tests to run as a single tox command
174 * Re-ogranizes the README and splits out the Developers guide, which is not needed by users.
183 * 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
184 * Adds a test "bombarding" script that tests this
193 * 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.
194 * Fix a bug in the unit tests (found using a fresh container with no RIC manifest!)
195 * Fix a (critical) bug in a1rmr due to a rename in the last iteration (RMR_ERR_RMR_RCV_RETRY_INTERVAL)
196 * Make unit tests faster by setting envs in tox
197 * Move to the now publically available rmr-python
198 * Return a 400 if am xapp does not expect a body, but the PUT provides one
199 * Adds a new test policy to the example RIC manifest and a new delayed receiver to test the aformentiond race condition
208 * Upgrade to rmr 0.10.0
209 * Fix bad api spec RE GET
210 * 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
219 * Rip some testing structures out of here that should have been in rmr (those are now in rmr 0.9.0, upgrade to that)
220 * Run Python BLACK for formatting
229 * Fix a blocking execution bug by moving from rmr's timeout to a non blocking call + retry loop + asyncronous sleep
230 * Changes the ENV RMR_RCV_TIMEOUT to RMR_RCV_RETRY_INTERVAL
239 * Update to rmr 0.8.3
240 * Change 503 to 504 for the case where downstream does not reply, per recommendation
241 * Add a 502 with different reasons if the xapp replies but with a bad/malformed/missing status
242 * Make testing much more modular, in anticipating of moving some unit test functionality into rmr itself
251 * Crash immediately if manifest isn't mounted
252 * Add unit tests for utils
262 * Upgrade A1 to rmr 0.8.0
263 * Go from deb RMR installation to git
264 * Remove obnoxious receiver logging
273 * Upgrade A1 to rmr 0.6.0
282 * Add license headers
291 * Introduce RIC Manifest
292 * Move some testing functionality into a helper module
293 * Read the policyname to rmr type mapping from manifest
294 * Do PUT payload validation based on the manifest
303 * Bump rmr python dep version
304 * Include a Dockerized test receiver
305 * Stencil out the mising GET
307 * Include a test docker compose file
316 * Initial Implementation
