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
25 Versioning <http://semver.org/>`__.
32 * Use base Docker with NNG version 1.1.1
41 * Upgrade RMR due to a bug that was preventing rmr from init in kubernetes
50 * Run unit tests as part of docker build
59 * Convert docs to appropriate format
60 * Move rmr string to int mapping to a file
69 * Use tavern to test the actual running docker container
70 * Restructures the integration tests to run as a single tox command
71 * Re-ogranizes the README and splits out the Developers guide, which is not needed by users.
80 * 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
81 * Adds a test "bombarding" script that tests this
90 * 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.
91 * Fix a bug in the unit tests (found using a fresh container with no RIC manifest!)
92 * Fix a (critical) bug in a1rmr due to a rename in the last iteration (RMR_ERR_RMR_RCV_RETRY_INTERVAL)
93 * Make unit tests faster by setting envs in tox
94 * Move to the now publically available rmr-python
95 * Return a 400 if am xapp does not expect a body, but the PUT provides one
96 * Adds a new test policy to the example RIC manifest and a new delayed receiver to test the aformentiond race condition
105 * Upgrade to rmr 0.10.0
106 * Fix bad api spec RE GET
107 * 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
116 * Rip some testing structures out of here that should have been in rmr (those are now in rmr 0.9.0, upgrade to that)
117 * Run Python BLACK for formatting
126 * Fix a blocking execution bug by moving from rmr's timeout to a non blocking call + retry loop + asyncronous sleep
127 * Changes the ENV RMR_RCV_TIMEOUT to RMR_RCV_RETRY_INTERVAL
136 * Update to rmr 0.8.3
137 * Change 503 to 504 for the case where downstream does not reply, per recommendation
138 * Add a 502 with different reasons if the xapp replies but with a bad/malformed/missing status
139 * Make testing much more modular, in anticipating of moving some unit test functionality into rmr itself
148 * Crash immediately if manifest isn't mounted
149 * Add unit tests for utils
159 * Upgrade A1 to rmr 0.8.0
160 * Go from deb RMR installation to git
161 * Remove obnoxious receiver logging
170 * Upgrade A1 to rmr 0.6.0
179 * Add license headers
188 * Introduce RIC Manifest
189 * Move some testing functionality into a helper module
190 * Read the policyname to rmr type mapping from manifest
191 * Do PUT payload validation based on the manifest
200 * Bump rmr python dep version
201 * Include a Dockerized test receiver
202 * Stencil out the mising GET
204 * Include a test docker compose file
213 * Initial Implementation
