Use compliant OMG IDL syntax

  • Legacy Issue Number: 16956
  • Status: closed  
  • Source: Object Computing, Inc. - OCI ( Mr. Adam Mitz)
  • Summary:

    IDL is defined by OMG’s own document formal/2011-11-01 in section 7. As another OMG specification (and most importantly, for clarity and precision), the current pseudo-IDL throughout the RTPS document must be changed to be actual compliant IDL. Compliant IDL does not use anonymous types: newly-constructed types appear in their own typedefs.
    Section: 9.2.2
    Page: 149
    Change: replace IDL with
    typedef octet OctetArray3[3];
    struct EntityId_t

    { OctetArray3 entityKey; octet entityKind; };

    Section: 9.3.1.1
    Page: 150
    Change: replace IDL with
    typedef octet GuidPrefix_t[12];

    Section: 9.3.1.2
    Page: 150
    Change: replace IDL with
    typedef octet OctetArray3[3];
    struct EntityId_t { OctetArray3 entityKey; octet entityKind; }

    ;

    Section: 9.3.1.5
    Page: 153
    Change: replace IDL with
    struct GUID_t

    { GuidPrefix_t guidPrefix; EntityId_t entityId; }

    ;

    Section: 9.3.2, Table 9.4 row “Time_t”
    Page: 153
    Change: replace IDL with
    struct Time_t

    { long seconds; unsigned long fraction; }

    ;

    Section: 9.3.2, Table 9.4 row “VendorId_t”
    Page: 153
    Change: replace IDL with
    typedef octet OctetArray2[2];
    struct VendorId_t

    { OctetArray2 vendorId; }

    ;

    Section: 9.3.2, Tables 9.4 and 9.5
    Page: 154-159
    Change: For ALL table entries with a struct move struct's identifier to directly follow the keyword "struct" (SequenceNumber_t, FragmentNumber_t, Locator_t, Count_t, ProtocolVersion_t, KeyHash_t, StatusInfo_t, ParameterId_t, ContentFilterProperty_t, ContentFilterInfo_t, OriginalWriterInfo_t, LocatorUDPv4_t) and in cases where "typedef" is used to introduce a struct, remove it (ProtocolVersion_t, ContentFilterProperty_t, ContentFilterInfo_t)
    Section: 9.3.2, Table 9.4
    Page: 155-157
    Change: Use of anonymous types is deprecated (applies to Locator_t::address, KeyHash_t::value, StatusInfo_t::value, all fields in ContentFilterProperty_t except for filterExpression). Replace the anonymous type with a typedef.
    Section: 9.3.2, Table 9.4
    Page: 157
    Change: Array bounds for FilterSignature_t must be at the end of the typedef
    Section: 9.4.2.6
    Page: 161
    Change: IDL syntax error due to use of anonymous types and the struct’s identifier must directly follow the keyword “struct”; also use unsigned long for bitmap
    Section: 9.4.2.8
    Page: 163
    Change: IDL syntax error due to use of anonymous types and the struct’s identifier must directly follow the keyword “struct”; also use unsigned long for bitmap
    Section: 9.4.2.11
    Page: 165
    Change: Use an unsigned short for “length” and mark this as "pseudo" IDL as there is no way to represent a sequence with a 2-byte length field or an array with runtime-determined bounds
    Section: 9.4.5.1
    Page: 168
    Change: struct’s identifier must directly follow the keyword “struct”
    Section: 9.6.2.1
    Page: 180
    Change: IDL syntax error due to use of anonymous types
    Section: 9.6.2.2
    Page: 181
    Change: IDL syntax error, the keyword "struct" is not used to identify types of fields. Also, IDL does not allow differences only in case so "WriterProxy writerProxy;" is ill-formed.
    Section: 10.1.1.1
    Page: 193
    Change: IDL syntax error, array bounds for Identifier must be at the end of the typedef, and the typedef keyword is missing.

Interpreting Liveliness Heartbeats

  • Legacy Issue Number: 11072
  • Status: closed  
  • Source: Real-Time Innovations ( Mr. Kenneth Brophy)
  • Summary:

    Source:
    Real-Time Innovations, Inc. (Ken Brophy, ken@rti.com)
    Summary:
    For better performance and simpler reliability, a liveliness heartbeat should be allowed to be a liveliness-only message without heartbeat semantics. As subclassed from a heartbeat, a liveliness heartbeat may trigger an ACKNACK response; to be a liveliness-only message, no ACKNACKs should be triggered. To enable this, setting the final flag should not trigger ACKNACKs.

    Resolution:
    A liveliness heartbeat with final-flag set must not trigger any ACKNACKs.

    Revised Text:
    Append to 8.4.2.3.2:

    The response is not required when a liveliness HEARTBEAT has both liveliness and final flags set to indicate it is a liveliness-only message.

Reader-side Heartbeat response suppression

  • Legacy Issue Number: 11071
  • Status: closed  
  • Source: Real-Time Innovations ( Mr. Kenneth Brophy)
  • Summary:

    Source:
    Real-Time Innovations, Inc. (Ken Brophy, ken@rti.com)
    Summary:
    The specification does not prevent multiple Heartbeats from arriving in rapid succession. For example, the piggyback heartbeat of a repair message may immediately be followed by a periodic wildcard heartbeat. In order to prevent duplicate repair sessions, the specification should define heartbeat suppression on the reader's side. This heartbeat response suppression should be handled by a reader attribute that controls the duration for which duplicate heartbeats would be ignored.

    Resolution:
    Add reader attribute, heartbeatSuppressionDuration, that defines the duration in which received heartbeats are suppressed from triggering duplicate ACKNACKs.

Clarify interoperability requirement 8.4.2.3.3

  • Legacy Issue Number: 11070
  • Status: closed  
  • Source: Real-Time Innovations ( Mr. Kenneth Brophy)
  • Summary:

    Real-Time Innovations, Inc. (Ken Brophy, ken@rti.com)
    Summary:
    The requirement contained in Section 8.4.2.3.3 is too restrictive and doesn't specify when resources can be reclaimed. If all Readers have acknowledged a sample, the Writer should be allowed to reclaim that sample's resources. Also, if a Reader NACKs a sample it has already ACKed, and the Writer is still able to provide a repair, it should.
    Resolution:
    Allow Writer to reclaim resources and send repairs if possible.
    Revised Text:
    Add the paragraph to the end of Section 8.4.2.3.3:

    Once a Writer has received positive acknowledgement from all Readers, the Writer can reclaim any associated resources. However, if a Writer receives a negative acknowledgement to a previously positively acknowledged sample, and the Writer can still service the request, the Writer should send the sample.

    Change: In NTP, TIME_ZERO represents a point in time in 1900. If this was followed by RTPS with its 31-bit field for positive seconds, the maximum point in time would be in 1968, long before RTPS was invented. Therefore the meaning of TIME_ZERO must be specified here. Additionally, leaving only 31 bits for positive seconds and assuming 1970 is used as TIME_ZERO, RTPS times are only valid through 2038. Is there a need for a sign bit in “seconds”?

  • Reported: DDSI-RTPS 2.0 — Tue, 27 Dec 2011 05:00 GMT
  • Disposition: Resolved — DDSI-RTPS 2.2
  • Disposition Summary:

    The format used is similar to NTP in that is uses seconds and fractions of a second
    (to make arithmetic simple) rather than seconds and nanoseconds. However it uses
    a signed seconds such that signed arithmetic can be applied.
    For these reasons and to facilitate conversion to operating system times (timeval and
    timespec) the time origin TIME_ZERO is defined to be the Unix prime epoch 0h, 1

    Change: The "register" Lifecycle operation is not discussed, should it be indicated with a zero value for StatusInfo_t? This should be explicit in the spec.

  • Reported: DDSI-RTPS 2.0 — Tue, 27 Dec 2011 05:00 GMT
  • Disposition: Resolved — DDSI-RTPS 2.2
  • Disposition Summary:

    The ‘register” operation is currently described as a local operation on the writer side
    and there is nothing in the specification requiring or preventing it from being
    propagated. From the reader perspective the registration will occur automatically the
    first time data is received for a particular instance.
    Most implementations do not propagate registrations, but in case some
    implementation chooses to do that we should clarify what the StatusInfo_t flags that
    would be associated with the submessage.
