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 the **GNU Lesser
|
|
General 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.
|
|
|
|
* Separate ``Face::registerPrefix()`` and ``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 the `NDN naming conventions (revision 1)
|
|
<https://named-data.net/publications/techreports/ndn-tr-22-ndn-memo-naming-conventions/>`_
|
|
(: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 ``PublicKey``, ``SecPublicInfo`` abstractions
|
|
|
|
+ New :ndn-cxx:`SignatureSha256WithEcdsa` signature type
|
|
|
|
+ Updates in ``Signature`` data structure to reflect changes in the `NDN-TLV spec v0.1.1
|
|
<https://docs.named-data.net/NDN-packet-spec/0.1.1/>`__
|
|
|
|
- **Wire encoding**
|
|
|
|
+ :ndn-cxx:`Data::getFullName` method to get the Data packet name including the implicit digest
|
|
|
|
+ :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` and :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 in ``setInterestFilter()`` and ``registerPrefix()`` (:issue:`1842`)
|
|
|
|
- **Miscellaneous tools**
|
|
|
|
+ Introduce :ndn-cxx:`Scheduler::cancelAllEvents` to cancel all previously scheduled events
|
|
(:issue:`1757`)
|
|
|
|
+ Introduce ``util::EventEmitter``, :ndn-cxx:`util::NotificationSubscriber`,
|
|
:ndn-cxx:`util::NotificationStream`, and :ndn-cxx:`nfd::FaceMonitor` utility classes
|
|
|
|
+ Introduce :ndn-cxx:`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:`1769`)
|
|
|
|
+ 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 in ``Face::removePendingInterest()`` (:issue:`1917`)
|
|
|
|
- **Wire encoding**
|
|
|
|
+ The Nonce field is now encoded as a 4-byte 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 to the
|
|
`NDN-TLV specification <https://docs.named-data.net/NDN-packet-spec/0.1.1/>`__
|
|
|
|
+ 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:
|
|
|
|
* ``preCertificateValidation`` to process received certificate before validation
|
|
* ``onTimeout`` to process interest timeout
|
|
* ``afterCheckPolicy`` to process validation requests
|
|
|
|
+ Fix memory issues in ``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 ``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 ``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 for 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.
