| RMR Release Notes |
| ================= |
| |
| The following is a list of release highlights for the RMR |
| library. At one point in time the RMR repo also housed a |
| wrapper library with a separate version and release cycle. |
| This resulted in *leap frogging* versions for each package; |
| the RMR core library was assigned odd major numbers (e.g. |
| 3.1.0). When the wrapper code was moved to a different repo |
| the need to leap frog versions ceased, and beginning with |
| version 4.0.0, the RMR versions should no longer skip. |
| |
| |
| 2021 March 31; version 4.7.0 |
| ---------------------------- |
| |
| The route table collector thread will capture the current |
| "offering" from the Route Manager (table generator) if the |
| RMR_SEED_RT environment variable is set. |
| |
| |
| |
| 2021 March 10; version 4.6.1 |
| ---------------------------- |
| |
| Corrected unit test "framework" to make manual testing |
| easier, and to add the ability to set the code optimisation |
| level via the CMake command line parameter OPT_LEVEL=n. |
| |
| |
| |
| 2021 February 22; Version 4.6.0 |
| ------------------------------- |
| |
| Enhanced to use millisecond based timestamps when writing log |
| messages. (RIC-627) |
| |
| Enhanced to eliminate the reqirement that the file specified |
| by the RMR_VCTL_FILE environment variable exist when RMR is |
| initialised. RMR will correctly find this file if it is |
| created after initialisation. Further, if the environment |
| variable is not given, the user may create and populate |
| /tmp/rmr.v at any time and the contents of this file will be |
| used as if it were supplied via the environment variable. |
| This should make debugging in existing containers easier. |
| |
| Enhanced to send an alarm manager when the user application |
| is not receiving messages fast enough. The original messages |
| written to the standard error are still generated. (RIC-204) |
| |
| |
| |
| 2021 January 21; Version 4.5.2 |
| ------------------------------ |

| |
| |
| |
| 2021 January 8; Version 4.5.0 |

| |
| |
| |
| 2020 April 21; version 4.0.0 |
| ---------------------------- |
| |
| The NNG based libraries are no longer included in the RMR |
| packages. This is considered a breaking change as NNG will |
| not be supported by default. It is still possible to build |
| with RMR-NNG libraries, but that is the exception. The API |
| between 3.8.2 and 4.0.0 is the SAME. Upgrading to 4.0.0 only |
| means that the underlying transport mechanism is limited only |
| to SI95. |
| |
| The rmr_rcv_specific() function has been deprecated as it was |
| necessary only for NNG and Nanomsg support. Its use should be |
| discontinued. |
| |
| |
| |

| SI95 has been removed. The length supplied during |
| initialisation is used as the "normal maximum" and default |
| buffer allocation size, but messages arriving which are |
| larger are accepted. (RIC-309) |

| payload was not always copied. |
| |
| |
| |
| 2019 November 13; version 1.12.1 |
| -------------------------------- |
| |
| New message type constants added to support A1. |
| |
| |
| |
| 2019 November 4; version 1.11.0 |
| ------------------------------- |
| |
| Version bump to move away from the 1.10.* to distinguish |
| between release A and the trial. |
| |
| |
| |
| 2019 November 7; version 1.12.0 |
| ------------------------------- |
| |
| Version cut to support continued development for next release |
| preserving the 1.11.* versions for release 1 (Amber) and |
| related fixes. |
| |
| |
| |
| 2019 October 31; version 1.10.2 |
| ------------------------------- |
| |
| Provide the means to increase the payload size of a received |
| message without losing the data needed to use the |
| rmr_rts_msg() funciton. |
| |
| |
| |
| 2019 October 21; version 1.10.1 |
| ------------------------------- |
| |
| Fix to prevent null message buffer from being returned by the |
| timeout receive function if the function is passed one to |
| reuse. |
| |
| |
| |
| 2019 October 21; version 1.10.1 |
| ------------------------------- |
| |
| Add periodic dump of send count info to stderr. |
| |
| |
| |
| 2019 September 27; version 1.9.0 |
| -------------------------------- |
| |
| Python bindings added receive all queued function and |
| corrected a unit test |
| |
| |
| |
| 2019 September 25; version 1.8.3 |
| -------------------------------- |
| |
| Correct application level test issue causing timing problems |
| during jenkins verification testing at command and merge |
| |
| Handle the NNG connection shutdown status which may now be |
| generated when a connection throug a proxy is reset. |
| |
| |
| |
| 2019 September 25; version 1.8.2 |
| -------------------------------- |
| |
| Correct bug in rmr_torcv_msg() when timeout set to zero (0). |
| |
| |
| |
| 2019 September 19; version 1.8.1 |
| -------------------------------- |
| |
| Correct missing constant for wrappers. |
| |
| |
| |
| 2019 September 19; version 1.8.0 |
| -------------------------------- |
| |
| New message types added: |
| RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED |
| |
| |
| |
| 2019 September 17; version 1.7.0 |
| -------------------------------- |
| |
| Initial connection mode now defaults to asynchronous. Set |
| RMR_ASYNC_CONN=0 in the environment before rmr_init() is |
| invoked to revert to synchronous first TCP connections. |
| (Recovery connection attempts have always been asynchronous). |
| |
| |
| |
| 2019 September 3; version 1.6.0 |
| ------------------------------- |
| |
| Fix bug in the rmr_rts_msg() function. If a return to sender |
| message failed, the source IP address was not correctly |
| adjusted and could cause the message to be "reflected" back |
| to the sender on a retry. |
| |
| Added the ability to set the source "ID" via an environment |
| var (RMR_SRC_ID). When present in the environment, the string |
| will be placed in to the message header as the source and |
| thus be used by an application calling rmr_rts_smg() to |
| return a response to the sender. If this environment variable |
| is not present, the host name (original behaviour) is used. |
| |
| |
| |
| 2019 August 26; version 1.4.0 |
| ----------------------------- |
| |
| New message types were added. |
| |
| |
| |
| 2019 August 16; version 1.3.0 |
| ----------------------------- |
| |
| New mesage types added. |
| |
| |
| |
| 2019 August 13; version 1.2.0 (API change, non-breaking) |
| -------------------------------------------------------- |
| |
| The function rmr_get_xact() was added to proide a convenient |
| way to extract the transaction field from a message. |
| |
| |
| |
| 2019 August 8; version 1.1.0 (API change) |
| ----------------------------------------- |
| |
| This change should be backward compatable/non-breaking A new |
| field has been added to the message buffer (rmr_mbuf_t). This |
| field (tp_state) is used to communicate the errno value that |
| the transport mechanism might set during send and/or receive |
| operations. C programmes should continue to use errno |
| directly, but in some environments wrappers may not be able |
| to access errno and this provides the value to them. See the |
| rmr_alloc_msg manual page for more details. |
| |
| |
| |
| 2019 August 6; version 1.0.45 (build changes) |
| --------------------------------------------- |
| |
| Support for the Nanomsg transport library has been dropped. |
| The library librmr.* will no longer be included in packages. |
| |
| Packages will install RMR libraries into the system preferred |
| target directory. On some systems this is /usr/local/lib |
| and on others it is /usr/local/lib64. The diretory is |
| determined by the sytem on which the package is built and |
| NOT by the system installing the package, so it's possible |
| that the RMR libraries end up in a strange location if the |
| .deb or .rpm file was generated on a Linux flavour that |
| has a different preference than the one where the package |
| is installed. |
| |
| |
| |
| 2019 August 6; version 1.0.44 (API change) |
| ------------------------------------------ |
| |
| Added a new message type constant. |
| |
| |
| |
| 2019 July 15; Version 1.0.39 (bug fix) |
| -------------------------------------- |
| |
| Prevent unnecessary usleep in retry loop. |
| |
| |
| |
| 2019 July 12; Version 1.0.38 (API change) |
| ----------------------------------------- |
| |
| Added new message types to RIC_message_types.h. |
| |
| |
| |
| 2019 July 11; Version 1.0.37 |
| ---------------------------- |
| |
| |
| librmr and librmr_nng |
| - Add message buffer API function rmr_trace_ref() |
| (see rmr_trace_ref.3 manual page in dev package). |
| |
| |
| |
| 2020 April 8; Version n/a |
| ------------------------- |
| |
| RMR Python moved to Python Xapp Framework |
| (https://gerrit.o-ran-sc.org/r/admin/repos/ric-plt/xapp-frame-py) |
| |
| |
| |
