ndn-cxx version 0.2.0
---------------------
Release date: August 25, 2014
Changes since version 0.1.0:
New features:
^^^^^^^^^^^^^
- **Base**
+ The license under which the library is released is changed to **Lesser GNU Public
License version 3.0**.
+ New ways to use incoming Interest dispatching:
* New :ndn-cxx:`InterestFilter` abstraction that supports filtering based on name
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
up application-specific ``OnInterest`` call dispatch using InterestFilters.
+ Add support for new `NDN naming conventions
<http://named-data.net/doc/tech-memos/naming-conventions.pdf>`_ (:issue:`1761`)
- **Security**
+ Add ``type dir`` :ref:`trust-anchor in ValidatorConfig <validator-conf-trust-anchors>`
to add all certificates under the specified directory as trust anchors.
The new option also allow periodic reloading trust anchors, allowing dynamic trust
models.
+ Added support for multiple signature types to :ndn-cxx:`PublicKey`,
:ndn-cxx:`SecPublicInfo` abstractions
+ New :ndn-cxx:`SignatureSha256WithEcdsa` signature type
+ Updates in :ndn-cxx:`Signature` data structure to reflect changes in `NDN-TLV spec
0.1.1 <http://named-data.net/doc/NDN-TLV/0.1.1/>`_
- **Wire encoding**
+ :ndn-cxx:`Data::getFullName() <getFullName()>` method to get :ndn-cxx:`Data` packet
name with implicit digest
+ New :ndn-cxx:`Name::getSuccessor()` method to get name successor (:issue:`1677`)
+ New in-wire refreshing of Interest's nonce (:issue:`1758`)
- **Management**
+ Support for :ndn-cxx:`ChannelStatus`, :ndn-cxx:`StrategyChoice` datasets
+ Defining new common Route Origins for NFD RIB management protocol (:issue:`1719`)
+ New RibEntry and Route data structures for RIB management protocol (:issue:`1764`)
+ Add support for RIB flags for setInterestFilter and registerPrefix (:issue:`1842`)
- **Miscellaneous tools**
+ Introduce :ndn-cxx:`Scheduler::cancelAllEvents` to cancel all previously scheduled events
(:issue:`1757`)
+ Introduce :ndn-cxx:`util::EventEmitter`, :ndn-cxx:`util::NotificationSubscriber`,
:ndn-cxx:`util::NotificationStream`, and :ndn-cxx:`nfd::FaceMonitor` utility classes
+ Introduce :ndn-cxx:`util::SegmentFetcher` helper class to fetch multi-segmented data
(:issue:`1879`)
- **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`)
+ Enforcing limit on Interest and Data packet size in :ndn-cxx:`Face::expressInterest` and
:ndn-cxx:`Face::put` methods (:issue:`1774`)
+ Cleaning up transport state on communication failure, so Face can try to reconnect
in the future.
+ Fix bug with Face::removePendingInterest (:issue:`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`)
- **Management**
+ Add link-layer byte counts in FaceStatus data structure (:issue:`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:`SecPublicInfoSqlite3`
- **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.
