8.3. Regressions in 7.2.0

The following regressions occurred in Connext 7.2.0, but nearly all were fixed by release 7.3.0 or 7.4.0. If you never installed release 7.2.0, you can ignore this section. See Regressions in 7.3.0.

8.3.1. Core Libraries

8.3.1.1. XCDR serialization of a mutable union with an unknown discriminator value is not compliant with OMG specification

This regression was introduced in 6.0.0 and has not yet been fixed. See XCDR serialization of a mutable union with an unknown discriminator value is not compliant with OMG specification in the 6.0.0 Regressions section.

8.3.1.2. Some properties no longer accept LENGTH_UNLIMITED string as valid value

This regression was introduced in 7.0.0 and is not yet fixed. See Some properties no longer accept LENGTH_UNLIMITED string as valid value in the 7.0.0 Regressions section.

8.3.1.3. Fixed in 7.4.0

8.3.1.3.1. Possible segmentation fault while enabling a DataWriter that enables batching

This regression was introduced in 7.0.0 and has been fixed in 7.4.0. See Possible segmentation fault while enabling a DataWriter that enables batching in the 7.0.0 Regressions section.

8.3.1.3.2. Running out of memory during DomainParticipant creation causes DomainParticipantFactory finalization to hang

This regression was introduced in 7.0.0 and has been fixed in 7.4.0. See Running out of memory during DomainParticipant creation causes DomainParticipantFactory finalization to hang in the 7.0.0 Regressions section.

8.3.1.4. Fixed in 7.3.0

8.3.1.4.1. Potential bus error when calling print and to_string APIs in TypeCode

This regression was introduced in 7.1.0 and is fixed in release 7.3.0. See Potential bus error when calling print and to_string APIs in TypeCode in the 7.1.0 Regressions section.

8.3.1.4.2. Sentinel constant for “invalid” Time contained unexpected value

Due to a regression in 7.2.0, the sentinel Time value that indicates an “invalid” timestamp is incorrect and doesn’t match the value of an “invalid” SampleInfo::source_timestamp (which can be returned when an instance state is NOT_ALIVE_NO_WRITERS). This makes a comparison such as the following to never be true:

if (info.source_timestamp() == Time::invalid()) {} // never true due to this bug

Starting in 7.3.0, Time::invalid() contains the expected sentinel value.

[RTI Issue ID CORE-14334]

8.3.1.4.3. Error message printed for each filtered sample when using writer-side filtering, FlatData, and Zero Copy over shared memory

When using FlatData, Zero Copy over shared memory, and writer-side filtering, every sample that is filtered incorrectly causes an error similar to the following to be logged:

ERROR [0x0101501F,0x044D6680,0xBF657AAB:0x80000002{Entity=DW,Topic=Example CameraImage,Type=CameraImage,Domain=0}|WRITE] REDAThresholdBufferPool_returnBuffer:!attempting to return a buffer to a pool that it was not allocated from.

There is no impact on functionally, the samples are still filtered correctly. This issue is fixed in 7.3.0.

[RTI Issue ID CORE-14144]

8.3.1.4.4. RTI Monitor unable to start due to missing nddsjava.jar in rti_connext_dds-7.2.0/lib/java in LM bundles

The nddsjava.jar file is missing in rti_connext_dds-7.2.0/lib/java, making RTI Monitor unable to start. You can work around this issue manually by copying nddsjava.jar from rti_connext_dds-7.2.0/lib/java to rti_connext_dds-7.2.0/resource/app/lib/java. This issue only affects LM bundles and is fixed in 7.3.0. It was also fixed in a 7.2.0 patch release.

[RTI Issue ID INSTALL-977]

8.3.2. Security Plugins

8.3.2.1. Fixed in 7.4.0

8.3.2.1.1. Segmentation fault in Java while enabling a DataWriter that protects payloads and enables batching

This regression was introduced in 7.0.0 and has been fixed in 7.4.0. See Segmentation fault in Java while enabling a DataWriter that protects payloads and enables batching in the 7.0.0 Regressions section.

8.3.2.2. Fixed in 7.3.0

8.3.2.2.1. Verbosity of security-related messages is per application

The last DomainParticipant explicitly setting the plugin-specific logging.verbosity property (set by you, in the QoS settings) will apply that setting to all the DomainParticipants within the application and all security-related messages logged from the Connext libraries. This is the behavior in all Connext releases, except for 7.2.0.

Connext 7.2.0 introduced support for running a combination of DomainParticipants from the Builtin Security Plugins library (nddssecurity) and the Lightweight Builtin Security Plugins library (nddslightweightsecurity) inside the same application. In 7.2.0, the logging verbosity (for all security-related messages) of all the DomainParticipants belonging to the same security library is determined by the last DomainParticipant of that library (as opposed to the last DomainParticipant within the application) that your application creates.

Connext 7.3.0 reverts this behavior. In 7.3.0, the logging verbosity for all security-related messages is again determined by the last DomainParticipant that your application creates.

[RTI Issue ID SEC-2368]

8.3.2.2.2. Memory leak when running Security Plugins SDK tester

Running a Security Plugins tester (AccessControlTester, CryptographyTester, or LightweightTester) causes a memory leak, because the testers don’t finalize the DomainParticipantFactory. This issue is fixed in 7.3.0. In 7.3.0, the testers call DDS_DomainParticipantFactory_finalize_instance() upon finalization.

[RTI Issue ID SEC-2279]

8.3.2.2.3. Wrong default Governance configuration for legacy Builtin Secure Logging topic

The Governance configuration for the DDS:Security:LogTopic legacy builtin topic is wrong in Security Plugins 7.2.0 by default. This issue prevents DDS:Security:LogTopic DataReaders from being interoperable with previous versions of Connext and with other vendors. The workaround is to manually configure the topic-level security attributes in the Governance Document:

<topic_rule>
    <topic_expression>DDS:Security:LogTopic</topic_expression>
    <enable_discovery_protection>false</enable_discovery_protection>
    <enable_liveliness_protection>false</enable_liveliness_protection>
    <enable_read_access_control>true</enable_read_access_control>
    <enable_write_access_control>false</enable_write_access_control>
    <metadata_protection_kind>SIGN</metadata_protection_kind>
    <data_protection_kind>ENCRYPT</data_protection_kind>
</topic_rule>

This issue is fixed in 7.3.0. In 7.3.0, there is no need to configure the builtin logging topic security attributes in the Governance Document. Subscriptions to both the legacy and non-legacy builtin logging topics work by default in 7.3.0.

8.3.3. Recording Service

8.3.3.1. Fixed in 7.4.0

8.3.3.1.1. <content_filter> tags did not work for Topic groups

This regression was introduced in 6.1.0 and has been fixed in 7.4.0. See <content_filter> tags did not work for Topic groups in the 6.1.0 Regressions section.

8.3.4. Limited Bandwidth Plugins

8.3.4.1. Fixed in 7.3.0

8.3.4.1.1. Limited Bandwidth ZRTPS transport crashes if an external compression library fails to load

This regression was introduced in 6.1.2 and is fixed in release 7.3.0. See Limited Bandwidth ZRTPS transport crashes if an external compression library fails to load in the 6.1.1/6.1.2 Regressions section.
