ndn-cxx version 0.3.0

Release date: February 2, 2015

Changes since version 0.2.0:

New features:

  • Build
    • The code now requires C++11. The minimum supported gcc version is 4.6, as earlier versions do not have proper support for C++11 features.
  • Base
    • Enable detailed version information when built from shallow clone or tarball (Issue #1915)
    • Make default transport configurable (Issue #2189)
    • Add ability to do partial Name comparison (Issue #2090)
  • Security
    • Add support for KeyDigest key locator (Issue #1426)
    • Add a method to get KeyDigest from a PublicKey instance (Issue #1964)
    • Add support for KeyChain to sign Interest using SHA256 digest (Issue #2218)
    • Add ndnsec-dsk-gen tool to generate a pair of Data-Signing-Key (DSK) for the specified identity (Issue #2246)
    • Pair-up PIB and TPM in KeyChain: PIB remembers the last used TPM type/location, which is used during KeyChain construction (unless overriden) (Issue #2242)
  • Wire encoding
    • Add support for application-defined meta information blocks (Issue #2021)
    • Introduce new name::Component::is* methods to allow checking if the name component follows the specific naming convention without relying on the exception handling (Issue #2088)
    • Add definition of producer-generated NACK (Issue #2111)
    • Add std::hash<Name> specialization to support unordered_map container (Issue #2147)
    • Add support for ImplicitSha256DigestComponent (Issue #1640)
    • Allow tagging Interest and Data packets with arbitrary information (Issue #2336)
  • Management
  • Miscellaneous tools
    • Add a new helper to calculate digests over dynamic inputs (Issue #1934)
    • Add DNS resolver helper (Issue #1918)
    • Import and re-license Ethernet and FaceUri classes from NFD codebase, add FaceUri canonization support for udp, tcp, and ether schemas (Issue #1994)
    • Add per-application in-memory storage with LRU, LFU, and FIFO replacement policies (Issue #1940)
    • Add ability to specialize system and steady clocks (e.g., for unit tests and simulation purposes) (Issue #2158)
    • Expose DummyClientFace as public API
    • New IndentedStream helper class to simplify writing to streams with the specified indents or prefixes (Issue #2238)
    • New Signal class template as an enhanced version of the deprecated EventEmitter (Issue #2279)
    • New scheduler::ScopedEventId helper to automatically cancel scheduled events upon destruction (Issue #2442)
    • New NetworkMonitor helper to detect network state changes (Issue #2443)

Updates and bug fixes:

  • Base
    • Prevent flags being set for rib/unregister command (Issue #1945)
    • Fix segfault caused by Face::unregisterPrefix when registeredPrefixId does not exist
    • Add explicit internal KeyChain to Face class. KeyChain previously existed in the Face as part of NFD controller class. (Issue #2039)
    • Properly disable assertions in release builds (Issue #2135)
    • Connect to Transport during construction of Face instance (Issue #2318)
  • Wire encoding
    • Fix segfault when decoding empty Exclude element (Issue #1970)
    • Provide EqualityComparable concept for Exclude element
    • Correct Marker in Name::appendVersion() (Issue #2086)
    • Ensure that wire-encoding errors are inherited from tlv::Error (Issue #1983)
  • Management
    • Replace FaceFlags with individual fields in face management data structures (Issue #1992)
    • ndn::nfd::Controller extended to allow generating ControlCommand for remote prefix registration (Issue #2039)
    • Change ForwarderStatus.NfdVersion to string (Issue #2003)
  • Security
    • Fix ndnsec-cert-gen to correctly infer prefix before KEY component (Issue #2052)
    • Help message corrections in ndnsec-cert-dump, ndnsec-cert-gen, and ndnsec-key-gen (Issue #2052)
    • Accept --sign-id and --cert-prefix in ndnsec-cert-revoke (Issue #2058)
    • Changes output format of ndnsec-cert-revoke to base64 encoding (Issue #2059)
    • Add a new (safer) option to ndnsec-cert-gen allowing inclusion of additional information blocks into the certificate. The new --signed-info parameter makes minimum assumptions, treating text before first space as OID and the rest as the associated string with this OID.
    • Make Face optional in Validator class (Issue #2124)
    • Display signature information when printing a certificate (Issue #2196)
    • Handle certificate decoding error in validation process (Issue #2212)
    • Fix segmentation fault in ndnsec-sign-req (Issue #2211)
    • Allow verbose option in ndnsec-list (Issue #2197)
    • Allow generation of DSK using ndnsec-key-gen (Issue #2247)
    • Allow ndnsec-key-gen to generate ECDSA keys (Issue #2248)
    • Fix memory leak in SecPublicInfoSqlite3 (Issue #2253)
    • Properly report status of ndnsec-delete execution (Issue #2275)
  • Miscellaneous tools
    • Fix incorrect tag map in tlvdump tool
    • Change to default resolver behavior in util::dns::Resolver (Issue #2415)
  • Documentation
    • Update of tutorials and installation instructions
    • Rename manpage of client.conf to ndn-client.conf (Issue #1967)
    • Updated and extended ndn-cxx code style:
      • add rules for some C++11 constructs
      • prefer BOOST_ASSERT and static_assert
    • Improve example applications (Issue #1976)
  • Tests
    • Improve security unit test cases (Issue #1683)
    • Embedding CI build and test running scripts into the repository
    • Partial unit test coverage for Face class (previously covered only by integration tests) (Issue #1947)
    • Improve stability of unit tests by using UnitTestTime (wall clock independent time) (Issue #2152)
  • Build
    • Redesign the way default compiler flags are determined (Issue #2209)
    • Support tools and examples with multiple translation units (Issue #2344)
    • Disable installation of internal headers and headers of the disabled components (Issue #2266, and Issue #2269)
    • Enable conditional compilation based on presence of getpass() function
