| prefixes and regular expressions. |
| |
| * Separated :ndn-cxx:`Face::registerPrefix()` and :ndn-cxx:`Face::setInterestFilter()` |
| methods allow distinct operations of registering with the local NDN forwarder and setting |

| |
| - **Build** |
| |
| + enabled support of precompiled headers for clang and gcc compilers to speed up compilation |
| |
| Updates and bug fixes: |
| ^^^^^^^^^^^^^^^^^^^^^^ |
| |
| - **Base** |
| |
| + Serialization of socket write operations |
| (`Issue #1707 <http://redmine.named-data.net/issues/1707>`_) |
| |
| + Enforcing limit on Interest and Data packet size in :ndn-cxx:`Face::expressInterest` |

| + Cleaning up transport state on communication failure, so Face can try to reconnect |
| in the future. |
| |
| + Fix bug with Face::removePendingInterest |
| (`Issue #1917 <http://redmine.named-data.net/issues/1917>`_) |
| |
| - **Wire encoding** |
| |
| + Nonce field is now encoded as 4-byte uint8_t value, as defined by NDN-TLV spec. |
| |
| + Optimized Data packet signing |
| |
| :ndn-cxx:`KeyChain::sign` method now pre-allocates :ndn-cxx:`EncodingBuffer`, requests |
| unsigned portion of :ndn-cxx:`Data` using ``Data::wireEncode(EncodingBuffer, true)``, |
| and then appends the resulting signature and prepends :ndn-cxx:`Data` packet header. |
| This way there is no extra memory allocation after :ndn-cxx:`Data` packet is signed. |
| |
| + Optimized implicit digest calculation in :ndn-cxx:`Interest::matchesData` method |
| (`Issue #1769 <http://redmine.named-data.net/issues/1769>`_) |
| |
| - **Management** |
| |
| + Add link-layer byte counts in FaceStatus data structure |
| (`Issue #1765 <http://redmine.named-data.net/issues/1765>`_) |
| |
| - **Security** |
| |
| + Allow user to explicitly specify the cert name prefix before 'KEY' component in |
| ``ndnsec-certgen`` |
| |
| + ``SignatureSha256`` has been renamed to :ndn-cxx:`DigestSha256` to conform with |
| `NDN-TLV specification <http://named-data.net/doc/ndn-tlv/>`_. |
| |
| + Add checking of ``Timestamp`` and ``Nonce`` fields in signed Interest within |
| :ndn-cxx:`ValidatorConfig` |
| |
| + Allow validator customization using hooks: |
| |
| Sub-classes of :ndn-cxx:`Validator` class can use the following hooks to fine-tune the |
| validation process: |
| |
| * :ndn-cxx:`Validator::preCertificateValidation <preCertificateValidation>` to |
| process received certificate before validation. |
| * :ndn-cxx:`Validator::onTimeout <onTimeout>` to process interest timeout |
| * :ndn-cxx:`Validator::afterCheckPolicy <afterCheckPolicy>` to process validation requests. |
| |
| + Fix memory issues in :ndn-cxx:`SecPublicInfoSqlite` |
| |
| - **Miscellaneous tools** |
| |
| + Redefine method for random number generation: ``random::generateWord*`` and |
| ``random::generateSecureWord*`` to generate cryptographically non-secure (fast) and |
| secure (slow) random numbers. |
| |
| - Other minor fixes and corrections |
| |
| Deprecated: |
| ^^^^^^^^^^^ |
| |
| - ``SignatureSha256`` class, use :ndn-cxx:`DigestSha256` instead. |
| |
| - All :ndn-cxx:`Face` constructors that accept ``shared_ptr<io_service>``. |
| |
| Use versions that accept reference to ``io_service`` object. |
| |
| - ``Face::ioService`` method, use :ndn-cxx:`Face::getIoService` instead. |
| |
| - :ndn-cxx:`Interest` constructor that accepts name, individual selectors, and individual |
| guiders as constructor parameters. |
| |
| Use ``Interest().setX(...).setY(...)`` or use the overload taking ``Selectors`` |
| |
| - ``name::Component::toEscapedString`` method, use :ndn-cxx:`name::Component::toUri` instead. |
| |
| - ``SecPublicInfo::addPublicKey`` method, use :ndn-cxx:`SecPublicInfo::addKey` instead. |
| |
| - ``Tlv::ConentType`` constant (typo), use ``Tlv::ContentType`` instead. |
| |
| - ``CommandInterestGenerator`` and ``CommandInterestValidator`` utility classes. |
| :ndn-cxx:`ValidatorConfig` should be used instead. |
| |
| Removed: |
| ^^^^^^^^ |
| |
| - support of ndnd-tlv (only NFD management protocol is supported now) |
| |
| - ``SecPublicInfoMemory`` and ``SecTpmMemory`` classes that were no longer used |
| |
| - Removing concept of periodic event from :ndn-cxx:`Scheduler`. |
| |
| In applications, periodic events should be just re-scheduled within the callback for |
| single-shot events. |
| |
| |
| |
| ndn-cxx v0.1.0 |
| ++++++++++++++ |
| |
| Release date: May 7, 2014 |
| |
| Version 0.1.0 is the initial release of ndn-cxx, an NDN C++ library with eXperimental |
| eXtensions. |
| |
| Originally based on `ndn-cpp library <https://github.com/named-data/ndn-cpp>`_ the ndn-cxx |
| library adopts a slightly different design philosophy (including an extensive use of Boost |
| libraries to facilitate development, as well as the use of Crypto++ library to support |
| cryptographic operations), and includes a number of extensions that aim to simplify NDN |
| application development. |
| |
| The current features include: |
| |
| - **Base** |
| |
| + Fully asynchronous, event-driven communication model, which is implemented using `Boost.Asio |
| <http://www.boost.org/doc/libs/1_48_0/doc/html/boost_asio.html>`_ |
| + Single-threaded, but thread-safe Face operations |
| |
| A single Face object can be safely used in multiple threads to express Interests and |
| publish Data packets |
| |
| + Explicit time management for NDN operations using `Boost.Chrono |
| <http://www.boost.org/doc/libs/1_48_0/doc/html/chrono.html>`_ |
| + Simplified and extended `NDN API <doxygen/annotated.html>`_ |
| + Extensive set of unit-tests based on `Boost.Test framework |
| <http://www.boost.org/doc/libs/1_48_0/libs/test/doc/html/index.html>`_ |
| |
| - Continuous integration using an in-house installation of Jenkins build bots and the |
| hosted `Travis CI <https://travis-ci.org/named-data/ndn-cxx>`_ continuous |
| integration service compile and verify correctness of the library for each commit |
| |
| - **Wire format** |
| |
| + Full support of `NDN-TLV packet format v0.1 <http://named-data.net/doc/NDN-TLV/0.1/>`_ |
| + Pure C++ implementation of wire encoding/decoding with simple access to wire format |
| of all NDN packet abstractions via ``wireEncode`` and ``wireDecode`` methods |
| |
| In many cases, NDN packet abstractions are just "indices" to the wire format |
| |
| - **Communication with the forwarder** |
| |
| + Enable connecting to local forwarder via UNIX and TCP transports and to remote |
| forwarders using TCP transport |
| + Full support for communication with `Named Data Networking Forwarding Daemon (NFD) |
| <https://github.com/named-data/NFD>`_ |
| |
| - Full support for `NFD management protocols |
| <http://redmine.named-data.net/projects/nfd/wiki/Management>`_ to NFD status |
| information, create and manage NFD Faces, receive NFD Face status change |
| notifications, update StrategyChoice for namespaces, and manage routes in RIB |
| - Support for `LocalControlHeader |
| <http://redmine.named-data.net/projects/nfd/wiki/LocalControlHeader>`_ to implement |
| special NDN applications that need low-level control of NDN packet forwarding |
| |
| - **Security support** |
| |
| + A set of security primitives to allowing implementation of secure NDN applications in |
| a simplified manner |
| |
| - **KeyChain**: provides simple interfaces of packet signing, and key and certificate |
| management |
| - **ValidatorConfig**: validator that implements trust model defined in a configuration |
| file |
| - **CommandInterestGenerator** and **CommandInterestValidator**: convenient helpers to produce |
| and validate command interests, while preventing potential replay attacks |
| |
| + Several implementations of trusted platform modules to securely manage private keys |
| |
| - **SecTpmOsx**: TPM based on OSX KeyChain (OSX-specific) |
| - **SecTpmFile**: TPM that uses file-based access control to protect keys (cross-platform) |
| |
| + Extensive set of security command-line tools to manage security identities and certificates |
| |
| - Generating private/public keys |
| - Issuing certificates |
| - Exporting/importing identities |
| - Managing default security settings |
| |
| - **Miscellaneous tools** |
| |
| + Scheduler to support delayed time operations |
| + NDN regular expressions |
| + Simple config file to alter various aspects of the library |
| + **tlvdump**: a simple tool to visualize TLV-encoded blocks |
