33 Fixes some bugs and possible memory likeage in SI95 code.
35 2021 December 2; version 4.8.0
36 Fixing memory leak in python support function (RIC-858).
37 New API added for debugging rmr rx queue (RIC-838).
39 2021 April 22; version 4.7.4
40 Beef up unit testing in SI package and fix a few static analysis
43 2021 April 19; version 4.7.3
44 Correct flag check bug in route table functions (RIC-777).
46 2021 April 9; version 4.7.2
47 Ensure that route table update received from route generator is not
48 applied before a full route table is received.
50 2021 April 2; version 4.7.1
51 Correct issues found during static code analysis.
53 2021 March 31; version 4.7.0
54 The route table collector thread will capture the current "offering"
55 from the Route Manager (table generator) if the RMR_SEED_RT environment
58 2021 March 10; version 4.6.1
59 Corrected unit test "framework" to make manual testing easier, and to
60 add the ability to set the code optimisation level via the CMake
61 command line parameter OPT_LEVEL=n.
63 2021 February 22; Version 4.6.0
64 Enhanced to use millisecond based timestamps when writing log messages.
67 Enhanced to eliminate the reqirement that the file specified by the
68 RMR_VCTL_FILE environment variable exist when RMR is initialised. RMR
69 will correctly find this file if it is created after initialisation.
70 Further, if the environment variable is not given, the user may create
71 and populate /tmp/rmr.v at any time and the contents of this file will
72 be used as if it were supplied via the environment variable. This should
73 make debugging in existing containers easier.
75 Enhanced to send an alarm manager when the user application is not
76 receiving messages fast enough. The original messages written to
77 the standard error are still generated. (RIC-204)
79 2021 January 21; Version 4.5.2

138 2020 August 3; Version 4.2.0
139 Add support for the RMR_RTREQ_FREQ environment variable to control
140 the request frequency for a new route table (default 5s if not
143 2020 July 21; Version 4.1.4
144 Fix bug in SI95 -- possible use of pointer after free (RIC-626).
146 2020 July 9; version 4.1.3
147 Allow RTS messages to be sent before the arrival of the initial
148 route table. Calls to RTS (heart beat responses) prior to the
149 initial route table load could cause a crash if a framework
150 blindly assumes that RTS is valid. (RIC-589)
152 2020 June 22; version 4.1.2
153 Fix typo in RIC Message header file.
155 Add document for message type constants and the scripts
158 2020 June 22; version 4.1.1

187 Correct message type constant for Traffic Steering predication (RIC-342)
189 2020 April 21; version 4.0.0
190 The NNG based libraries are no longer included in the RMR packages.
191 This is considered a breaking change as NNG will not be supported by
192 default. It is still possible to build with RMR-NNG libraries, but
193 that is the exception. The API between 3.8.2 and 4.0.0 is the SAME.
194 Upgrading to 4.0.0 only means that the underlying transport mechanism
195 is limited only to SI95.
197 The rmr_rcv_specific() function has been deprecated as it was necessary
198 only for NNG and Nanomsg support. Its use should be discontinued.
200 2020 April 20; version 3.8.2

202 table updates. (RIC-336)
204 2020 April 20; version 3.8.1

211 segment fault when in level 2 debug (RIC-335)
213 2020 April 15; version 3.7.4
214 Add missing message type to header file (RIC-334)

219 2020 April 10; version 3.7.2
220 Fix bug related to static route table only mode (RIC-331)
222 2020 April 9; version 3.7.1
223 The max length restriction for receiving messages when using SI95 has
224 been removed. The length supplied during initialisation is used as
225 the "normal maximum" and default buffer allocation size, but messages
226 arriving which are larger are accepted. (RIC-309)
228 2020 April 7; version 3.7.0
229 The health check support programme was renamed to rmr_probe (RIC-308).
231 2020 April 6; version 3.6.6

329 2020 January 16; version 3.0.0
330 Introduce support for SI95 transport library to replace NNG.
331 (RMR library versions will use leading odd numbers to avoid tag collisions
332 with the wrapper tags which will use even numbers.)
334 2019 December 9; version 1.13.1
335 Correct documentation and missing rel-notes update for RTD.
337 2019 December 6; version 1.13.0

354 preserving the 1.11.* versions for release 1 (Amber) and
357 2019 October 31; version 1.10.2
358 Provide the means to increase the payload size of a received message
359 without losing the data needed to use the rmr_rts_msg() funciton.
361 2019 October 21; version 1.10.1
362 Fix to prevent null message buffer from being returned by the timeout
363 receive function if the function is passed one to reuse.
365 2019 October 21; version 1.10.1
366 Add periodic dump of send count info to stderr.
368 2019 September 27; version 1.9.0
369 Python bindings added receive all queued function and corrected a unit test
371 2019 September 25; version 1.8.3
372 Correct application level test issue causing timing problems during
373 jenkins verification testing at command and merge
375 Handle the NNG connection shutdown status which may now be
376 generated when a connection throug a proxy is reset.
378 2019 September 25; version 1.8.2
379 Correct bug in rmr_torcv_msg() when timeout set to zero (0).
381 2019 September 19; version 1.8.1
382 Correct missing constant for wrappers.
384 2019 September 19; version 1.8.0
385 New message types added:
386 RAN_CONNECTED, RAN_RESTARTED, RAN_RECONFIGURED
388 2019 September 17; version 1.7.0
389 Initial connection mode now defaults to asynchronous. Set RMR_ASYNC_CONN=0
390 in the environment before rmr_init() is invoked to revert to
391 synchronous first TCP connections. (Recovery connection attempts
392 have always been asynchronous).
394 2019 September 3; version 1.6.0
395 Fix bug in the rmr_rts_msg() function. If a return to sender message
396 failed, the source IP address was not correctly adjusted and could
397 cause the message to be "reflected" back to the sender on a retry.
399 Added the ability to set the source "ID" via an environment var
400 (RMR_SRC_ID). When present in the environment, the string will
401 be placed in to the message header as the source and thus be used
402 by an application calling rmr_rts_smg() to return a response to
403 the sender. If this environment variable is not present, the host
404 name (original behaviour) is used.
406 2019 August 26; version 1.4.0
407 New message types were added.
409 2019 August 16; version 1.3.0
410 New mesage types added.
412 2019 August 13; version 1.2.0 (API change, non-breaking)
413 The function rmr_get_xact() was added to proide a convenient
414 way to extract the transaction field from a message.
416 2019 August 8; version 1.1.0 (API change)
417 This change should be backward compatable/non-breaking
418 A new field has been added to the message buffer (rmr_mbuf_t).
419 This field (tp_state) is used to communicate the errno value
420 that the transport mechanism might set during send and/or
421 receive operations. C programmes should continue to use
422 errno directly, but in some environments wrappers may not be
423 able to access errno and this provides the value to them.
424 See the rmr_alloc_msg manual page for more details.
426 2019 August 6; version 1.0.45 (build changes)
427 Support for the Nanomsg transport library has been dropped.
428 The library librmr.* will no longer be included in packages.
430 Packages will install RMR libraries into the system preferred
431 target directory. On some systems this is /usr/local/lib
432 and on others it is /usr/local/lib64. The diretory is
433 determined by the sytem on which the package is built and
434 NOT by the system installing the package, so it's possible
435 that the RMR libraries end up in a strange location if the
436 .deb or .rpm file was generated on a Linux flavour that
437 has a different preference than the one where the package
440 2019 August 6; version 1.0.44 (API change)
441 Added a new message type constant.
443 2019 July 15; Version 1.0.39 (bug fix)
444 Prevent unnecessary usleep in retry loop.
446 2019 July 12; Version 1.0.38 (API change)
447 Added new message types to RIC_message_types.h.
449 2019 July 11; Version 1.0.37
451 librmr and librmr_nng
452 - Add message buffer API function rmr_trace_ref()
453 (see rmr_trace_ref.3 manual page in dev package).
