1 Megaco Release Notes
This document describes the changes made to the Megaco system
from version to version. The intention of this document is to
list all incompatibilities as well as all enhancements and
bugfixes for every release of Megaco. Each release of Megaco
thus constitutes one section in this document. The title of each
section is the version number of Megaco.
1.1 Megaco 3.2.3
Version 3.2.3 supports code replacement in runtime from/to
version 3.2.2, 3.2.1 and 3.2 except
when using any of the drivers (flex for text or asn1 for binary).
1.1.1 Improvements and new features
-
Assumed a more strict approach to the return values of
the callback functions of the
megaco_user behaviour.
Now, a return value other then what is described in
the behaviour documentation, will result in a warning
message.
Except for the
handle_trans_request/3 and
handle_trans_request_long/3,
which still results in error messages.
Own Id: OTP-5830
Aux Id: Seq 10148
-
Introduced a strict version control (strict_version)
connection info and user info option. See the
user_info and
conn_info functions
for more info.

1.2.1 Improvements and new features
-
1.2.2 Fixed bugs and malfunctions
-
Digit Map: Megaco does not handle "unexpected event"
according to chapter 7.1.14.5 point 5. See
eval_digit_map
and
test_digit_event.
Own Id: OTP-5799
Aux Id: Seq 10085
-
The text codec of prev3b should handle
encoding/decoding of indAudMediaDescriptor as specified
in the final version of the v3 spec. This is backward
compatible and more aligned with the ASN.1.
Own Id: OTP-5803
Aux Id: Seq 10119
-
Flex scanner cannot handle empty local/remote
descriptors.
Own Id: OTP-5804
Aux Id: Seq 10119
-
Text codecs does not handle messages of unsupported versions
(or with incorrect version) in a good way.
Own Id: OTP-5805
Aux Id: Seq 10131
-
The documentation of the reply-timer was unclear.
Own Id: OTP-5816
Aux Id: Seq 10142
1.2.3 Incompatibilities
1.3 Megaco 3.2.1
Version 3.2.1 supports code replacement in runtime from/to
version 3.2 except
when using any of the drivers (flex for text or asn1 for binary).
1.3.1 Improvements and new features
-
In order to allow the user to drop (ignore) a transaction
request a new return value,
ignore_trans_request
, has
been added to the
handle_trans_request/3
callback function.
Own Id: OTP-5725
Aux Id: Seq 10084
1.3.2 Fixed bugs and malfunctions
-
Text encoding of the termination id list in
contextTerminationAudit incorrect. Missing { }.
All versions.
Own Id: OTP-5793
Aux Id: Seq 10116
1.3.3 Incompatibilities
-
1.4 Megaco 3.2
Version 3.2 supports code replacement in runtime from/to
version 3.1 and 3.0.1 except
when using any of the drivers (flex for text or asn1 for binary).
1.4.1 Improvements and new features
-
Added support for another pre version of v3 (
prev3b
).
This is basically the same as prev3a
except that
context priority (in contextProperties) has been
"fixed" so that it is backward compatible with v2.
Own Id: OTP-5717
1.4.2 Fixed bugs and malfunctions
-
The (digit map)
test and
eval function(s)
was lacking result info on what kind of completion
was done;
full
or unambiguous
.
Own Id: OTP-5750
Aux Id: Seq 10085
1.4.3 Incompatibilities
1.5 Megaco 3.1
Version 3.1 supports code replacement in runtime from/to
version 3.0.1 and 3.0 except
when using any of the drivers (flex for text or asn1 for binary).
1.5.1 Improvements and new features
-
The
megaco_incr_timer
has been tweaked so that the
max_retries field can now also take the value
infinity_restartable
. This means that the only way
to actually restart the timer is if some external event
occurs, e.g. a pending message when the long request timer
is running. That is, if the timeout time actually expires,
then so does the timer.
Own Id: OTP-5619
Aux Id: Seq 9845
-
Added function
format_versions
to print the extended version info produced by the
versions1 and
versions2
functions.
Own Id: OTP-5664
1.5.2 Fixed bugs and malfunctions
-
Incorrect text encoding of embedded Events.
Own Id: OTP-5601
-
Incorrect text encoding of embedded Signal.
Own Id: OTP-5600
-
Misc bugs detected by Dyalizer.
Own Id: OTP-5597
-
Encoding of SDP was in text not done strictly
according RFC2327. Each line should be terminated
with carriage return and newline (0x0d0a), but was only
terminated with single newline (0x0a).
Own Id: OTP-5542
Aux Id: Seq 9669
1.5.3 Incompatibilities
-
1.6 Megaco 3.0.1
Version 3.0.1 supports code replacement in runtime from/to
version 3.0 except
when using any of the drivers (flex for text or asn1 for binary).
1.6.1 Improvements and new features
-
1.6.2 Fixed bugs and malfunctions
-
Pending limit cleanup error's.
In some situations (high load), reply-records where never removed,
blocking new requests with the same transaction id.
Own Id: OTP-5401
-
Added utility functions to retrieve some system and application
info, see
versions1 and
versions2.
Own Id: OTP-5446
-
When the
enable_trace
function is called with the
File
argument, it sets
up dbg
so that trace events are written as plain text
to the given file (using io:format
).
Own Id: OTP-5447
1.6.3 Incompatibilities
-
The
File
argument to the function
enable_trace no
longer sets up dbg
to write the trace events directly to
file but instead to be written to a plain text file using
io:format
.
Also enable_trace
no longer accepts the argument
{io, Verbosity}
.
Own Id: OTP-5447
1.7 Megaco 3.0
1.7.1 Improvements and new features
-
Implementation of the Megaco v2 corrigendum 1 (03/2004).
This means in short:
-
The ModemDescriptor has been deprecated.
If this descriptor is found in a received message
it will be ignored (removed from the message).
If an attempt is made to encode a message containing
a ModemDescriptor, an error will be returned.
If in the binary codec case, encoding-config
contains native, then the ModemDescriptor
will however be included in the message when encoding and
also decoded. This means that it in this case it is up the
user to never include the ModemDescriptor in a
transmitted message and to ignore it, if received.
-
Addition of the EmergencyOffToken, which is used
in the contextProperty.
Own Id: OTP-5204
-
Added receiving pending limit config property. This is
the limit for the number of pending messages that is
accepted before a request is considered "a lost cause".
Own Id: OTP-5220
-
Added support for preliminary version 3. Based on TD-33.
See chapter Handling megaco versions on how to configure and
use the preliminary version 3 (prev3a).
Own Id: OTP-5236
-
Added configure thread support.
Own Id: OTP-5351
1.7.2 Fixed bugs and malfunctions
-
When text encoding the ServiceChangeParm in v2, the
serviceChangeInfo field was ignored.
Own Id: OTP-5352
-
When text parsing serviceChangeParm in v2, all of auditItem
was put into the auditToken field of the AuditDescriptor
(the serviceChangeInfo field of the ServiceChangeParm record).
The indAudterminationAudit should go into the auditPropertyToken
field.
Own Id: OTP-5353
-
Binary name resolver was based on RFC 2885 (version 0.8
of the megaco standard). Among other things the
package id numbering was incorrect.
This is the case both for version 1 and 2.
Own Id: OTP-5272
1.7.3 Incompatibilities
-
Package number scheme (among other things) was changed
in version 1 of the standard..
Own Id: OTP-5272
-
The config property orig_pending_limit has been
renamed to sent_pending_limit.
Own Id: OTP-5220
1.8 Megaco 2.1.8
Version 2.1.8 supports code replacement in runtime from/to
version 2.1.7 and 2.1.6 except
when using any of the drivers (flex for text or asn1 for binary).
1.8.1 Improvements and new features
-
1.8.2 Fixed bugs and malfunctions
-
The error counter medGwyGatewayNumErrors did not work.
This counter is incremented by the megaco application
when decode of a message fails. Due to the
construction of the decoders, nothing beyond the
error reason (in the text case, basically an
unintelligible list of tokens) is returned. E.g. not
the Mid needed to be able to deduce which MG
(conn-handle), this message came from. This resulted
in an increment of the "global" medGwyGatewayNumErrors
counter instead of the connection specific.
This has been fixed. In the text case by adding a mini
decoder, that basically only decodes the message as
far as the Mid (if the error is in or before the Mid,
then this decoder also fails).
Own Id: OTP-5296
Aux Id: Seq 9669
-
When the
megaco:cancel/2
function is called, the
megaco application is supposed to perform a cleanup.
E.g. remove aut-dated request and reply records. For
the reply-records this did not work, since it only
removed those record which had the state field
set to wait_for_ack, and not aborted!
If the state had been set to aborted and not
yet been removed (which normally happens when
the reply_timer times out) when the disconnect
and cancel functions where called, those records
would never be removed. This means that if eventually
a transaction was received which had the same
transaction-id as the aborted reply, this whould
just be ignored!
Own Id: OTP-5310
Aux Id: Seq 9668
-
Incorrect definition of hexdig in the flex-scanner.
Angelo Contardi
Own Id: OTP-5312
-
Various cleanup of the v2 text parser:
1) Removed unused nonterminal and rule digitMapName.
2) Token 'TimeStampToken' also a safeToken.

1.9 Megaco 2.1.7
Version 2.1.7 supports code replacement in runtime from/to
version 2.1.6, 2.1.5, 2.1.4, 2.1.3, 2.1.2, 2.1.1 and 2.1 except
when using any of the drivers (flex for text or asn1 for binary).

-
1.10 Megaco 2.1.6
Version 2.1.6 supports code replacement in runtime from/to
version 2.1.5, 2.1.4, 2.1.3, 2.1.2, 2.1.1 and 2.1 except when using
any of the drivers (flex for text or asn1 for binary).
1.10.1 Improvements and new features
-
Minor error handling improvement to the text encoder.
Own Id: OTP-5193
1.10.2 Fixed bugs and malfunctions
-
The megaco text codec failed to properly encode a message
containing no or an empty terminationAudit list or possibly
a terminationAudit list with only an "empty" emptyDescriptor
(e.g. an AuditDescriptor without any values; auditToken is
either asn1_NOVALUE or []). This effected AmmsReply and
auditOther (AuditResult) and both v1 and v2.
Own Id: OTP-5186
Aux Id: Seq 9226
-
Version 2 codec corrections: Incorrectly transformed (encoded
and decoded) IndAudStreamDescriptor (binary), encoded
IndAudMediaDescriptor and IndAudStreamDescriptor (text).
Incorrectly decoded IndAudMediaDescriptor (text).
Own Id: OTP-5201
1.10.3 Incompatibilities
-
1.11 Megaco 2.1.5
Version 2.1.5 supports code replacement in runtime from/to
version 2.1.4, 2.1.3, 2.1.2, 2.1.1 and 2.1 except when using
any of the drivers (flex for text or asn1 for binary).
1.11.1 Improvements and new features
-
1.11.2 Fixed bugs and malfunctions
-
Bad error message when encoding invalid termination id.
Own Id: OTP-5133
Aux Id: Seq 9153
-
The included tcp transport module had a possible
message queue accumulation loophole. If the
connection is terminated between the calls
gen_tcp:accept/1 and gen_tcp:controlling_process/2
we did not clean up the message queue.
Also, if controlling_process failes, a cleanup must
be done.
Own Id: OTP-5130
1.11.3 Incompatibilities
-
1.12 Megaco 2.1.4
Version 2.1.4 supports code replacement in runtime from/to
version 2.1.3, 2.1.2, 2.1.1 and 2.1 except when using any of the
drivers (flex for text or asn1 for binary).
1.12.1 Improvements and new features
-
1.12.2 Fixed bugs and malfunctions
-
Failure to decode indAudLocalControlDescriptor with
more then one indAudlocalParm.
This applies only to version 2.
Own Id: OTP-5106

-
1.13 Megaco 2.1.3
Version 2.1.3 supports code replacement in runtime from/to
version 2.1.2, 2.1.1 and 2.1 except when using any of the
drivers (flex for text or asn1 for binary).
1.13.1 Improvements and new features
-
1.13.2 Fixed bugs and malfunctions
-
Failure to encode a ActionReply with empty contextReply
(asn1_NOVALUE) and commandReply ([]).
Failure to decode ActionReply with error descriptor with
non-empty contextReply and/or commandReply.
This applies to both version 1 and 2.
Own Id: OTP-5085
1.13.3 Incompatibilities
-
1.14 Megaco 2.1.2

Encoding of a MediaDescriptor fails if the
streams part is empty (asn1_NOVALUE).
Own Id: OTP-5068
1.14.3 Incompatibilities
-
1.15 Megaco 2.1.1
Version 2.1.1 supports code replacement in runtime from/to
version 2.1 except when using any of the drivers (flex for
text or asn1 for binary).
1.15.1 Improvements and new features
-
1.15.2 Fixed bugs and malfunctions
-
A pretty text message containing an ObservedEvents
without timestamp, will fail to decode. This effects
both v1 and v2.
Own Id: OTP-5042
-
During node restart in a high load scenario,
the megaco_messenger:receive_reply_remote function
could be called on a node before the megaco app
has actually been started. This will result in a
crash (EXIT with badarg). This is now handled in the
same way as if the request was not found (with a
call to the callback function handle_unexpected_trans).
Own Id: OTP-5025
Aux Id: Seq 8658
1.15.3 Incompatibilities
-
1.16 Megaco 2.1
1.16.1 Improvements and new features
-
Allow separatelly encode action requests. Handle sending
of those previously encoded action requests as binaries
(as well as lists of action requests).
See
encode_actions,
call and
cast.
-
Introduce a transaction sender process (one for each
connection) which will accumulate transactions and send
several in one message.
See transaction sender,
user_info and
conn_info.
-
New encoding-config options for the erl_dist encoder which
makes it possible to compress the megaco messages. This makes
the erl_dist encoded message much more compact (about 1/3 of
the size).
See megaco_compressed.
1.16.2 Fixed bugs and malfunctions
-
Text parser(s) did not handle parsing of the StreamId field of
RequestedEvent and SecondRequestedEvent.
Own Id: OTP-4974
-
Repeated transaction request receiving when exceeding
pending limit will cause the message handling process
to crash.
Own Id: OTP-4956
Aux Id: Seq 8445
-
Text parser did not handle auditReturnItem properly,
as defined in IGv11.
Own Id: OTP-4950
-
Missing [text] servChgReplyParm constistency check.
Own Id: OTP-4949
-
Incorrect handling of comments in text messages.
Own Id: OTP-4946
-
Missing [text] serviceChangeParm constistency check.
Own Id: OTP-4945
1.16.3 Incompatibilities
-
Text parser did not handle auditReturnItem properly,
as defined in IGv11. The result which was supposed to
have been presented as the tuple:
{emptyDescriptor, #'AuditDescriptor{}}
in the termination audit list, was instead entered as
{auditReturnItem, atom()}
in the termination audit list. This has been fixed.
Own Id: OTP-4950
-
In previous releases there where a couple of user and
connection config items dealing with accumulating
transaction ack sending. These has all been renamed
due to the introduction of the transaction sender.
See transaction sender,
user_info and
conn_info.
1.17 Megaco 2.0.1
1.17.1 Improvements and new features
-
1.17.2 Fixed bugs and malfunctions

Own Id: OTP-4920
-
Text encoding of hex-digits sometimes incorrect.
Own Id: OTP-4921

-
1.18 Megaco 2.0
1.18.1 Improvements and new features
-
Support for both version 1 & 2 of the Megaco standard,
updated according with IGv10-13.
Version selection is described in chapter
Handling megaco versions 1 & 2.
-
It is now possible to use the ASN.1 linked in driver
for decode/encode of messages (encoding config driver).
See chapter
Configuration of binary encoding module(s).
-
Added a new configuration parameter, orig_pending_limit, to
support the xOriginatingPendingLimit (x = MG or MGC)
property in the root package.
See the
orig_pending_limit
parameter of the user_info function (also conn_info).
-
Added a new configuration parameter, threaded.
This tells the megaco app, that all
transaction requests in a message should be executed
in parallel (e.g. each in it's own process).
See the
threaded parameter
of the user_info function (also conn_info).
-
Added behaviour modules
megaco_transport and
megaco_encoder.
-
Added new (message) test functions to the megaco module, see
test_request and
test_reply.
-
Minor improvements to the tracing.
-
Minor improvements to the simple example.
1.18.2 Fixed bugs and malfunctions
-
Update of the request timer incorrect when receiving
a pending message. Could cause an exit of the process
handling the message and a subsequent call to the
handle_disconnect
callback function.
Own Id: OTP-4836
-
Failed stopping the request timer when receiving a reply.
The only effect this had was that the request timer
possibly ran one extra time (without doing anything).
Own Id: OTP-4843
1.18.3 Incompatibilities
-
signalsDescriptor has changed i v2
-
ServiceChangeProfile has changed in v2
1.19 Megaco 1.2.3
1.19.1 Improvements and new features
-
1.19.2 Fixed bugs and malfunctions
-
Megaco re-transmission loop, when setting the long request timer
to an inremental timer. Megaco changes to the long request timer
when receiving an pending message (after having sent a request).
Each time the (long) timer expire, it will incorrectly result in
an re-send of the request. This is meaningless since we know from
the received pending that the "other side" has received the request
and is working on it. Furthermore, when in this case the "other
side" receives the request again, it will send another pending
message. Receiving a pending message in this case will
restart the timer (reset it to the initial values). This
means that the timer will actually never fully expire and the two
stacks will continue to exchange request/pending messages for as
long as the "other side" is working on the request.

Own Id: OTP-4710
1.20.3 Incompatibilities
When downgrading form 1.2.2, reply-timers started when running
1.2.2 will not be properly handled since the format has changed.
An error message will be printed when they expire.
1.20.4 Known bugs and problems
-
1.21 Megaco 1.2.1
Version 1.2.1 only supports code replacement in runtime from/to
version 1.2.
1.21.1 Improvements and new features
-
This is just a code up-/downgrade cleanup release. I.e. It's the
same as version 1.2 minus the ugly stuff needed to handle up-/downgrade
from/to version 1.1.2, 1.1.1 and 1.1.0.

It is now possible to send more then one transaction (request)
in a message. See call
and cast.
Req Id: M[4]-1
Own Id: OTP-4589
-
Two new parameters for user and connection info has been added:
accu_ack_timer
and accu_ack_maxcount
.
These are used together with the auto_ack
flag and control
whether the acks should be sent immediatly or accumulated (and sent
later). Note that this has nothing to do with the
immAckRequired
-flag in reply transactions.
See user_info
and conn_info.

1.22.2 Fixed bugs and malfunctions
-
TCP transport supervision error (cut-and-paste error).
The megaco_tcp worker child was started as if it where a
supervisor (and not a worker) and with a dependency to
megaco_tcp_connection_sup (which it has none)
Own Id: OTP-4649
-
Encoding of transaction ack fails with id ranges.
This was not really a problem in previous releases
since such a message was never created (Ack was, possibly,
sent for each received transaction reply).
Own Id: OTP-4652
1.22.3 Incompatibilities
-
1.22.4 Known bugs and problems
-
Neither the TCP nor the UDP transport mechanisms are
part of the megaco supervsion tree. This makes code up-/downgrade
difficult when either of them are used as transport.
This will be fixed in a future release of megaco.

A message containing a transaction request without the transaction id value
is incorrectly reported back to the sender with a just an ErrorDescriptor.
The correct behaviour is describen in chapter 8.1.1 of RFC 3015.
Now the result will be a transactioReply with transaction id = 0 and an
ErrorDescriptor.

1.28 Megaco 1.0.2
1.28.1 Improvements and new features
-
Added another binary decoder; per_bin.
To be able to use the per_bin encoder the ASN.1
application of version 1.3.2 or later is needed for R8B systems.
For R7B01, ASN.1 of version 1.3.1.3 or later must be used.
1.28.2 Fixed bugs and malfunctions
-
Memory leak in the flex scanner. Message larger then approx.
1000 bytes cannot be decoded. Will cause a core dump!
Note that this will only be a problem if the flex scanner
has been configured as encoding/decoding module!
