Pyndn

----------------------------

Changes
* https://redmine.named-data.net/issues/3798 In KeyChain.verifyData and verifyInterest,
use onValidationFailed callbacks which include a reason string.
* https://github.com/named-data/PyNDN2/pull/3 In Node, support a callable object
for onInterest. (Thanks Pedro!)
* https://redmine.named-data.net/issues/3543 Support for Link objects in the
encrypt package Producer and Consumer.
* https://redmine.named-data.net/issues/3922 In ChronoSync2013, support optional
application info in the SyncState messages.
* In Blob, if isNull(), changed toRawStr() to return "" instead of None.
* ChronoSync2013: Added method getProducerPrefixes().

Deprecated
* In KeyChain, deprecated verifyData that takes an onValidationFailed(data)
callback without a reason string. You should use the callback with the reason
string.
* In KeyChain, deprecated verifyInterest that takes an onValidationFailed(interest)
callback without a reason string. You should use the callback with the reason
string.

----------------------------

Changes

* Added support for the Name component type ImplicitSha256Digest, and methods:
Name.Component.fromImplicitSha256Digest, isGeneric and isImplicitSha256Digest.
Name.appendImplicitSha256Digest.
* In SegmentFetcher.fetch, allow a validatorKeyChain for asynchronous Data validation.
* https://redmine.named-data.net/issues/3447 In Data, added getFullName, and
in Interest added matchesData to use it.
* INSTALL: Added instructions to build the optional _pyndn C module for faster
encoding/decoding.

----------------------------

Breaking changes
* In encrypt/Consumer, moved ErrorCode to encrypt/EncryptError, affecting the
onError callback to Consumer.consume.

Changes
* In MemoryContentCache.registerPrefix, added optional onRegisterSuccess. (Thanks to Zhehao Wang.)

* In Interest, added methods to support link objects and SelectedDelegation:
hasLink, getLink, unsetLink, get/setLinkWireEncoding, get/setSelectedDelegationIndex.
* Added support for NDNLPv2:
In Face.expressInterest, added an OnNetworkNack callback.
In Interest and Data, the method getIncomingFaceId provides the incoming face ID (if configured).
* http://redmine.named-data.net/issues/3260 Added GenericSignature.
* http://redmine.named-data.net/issues/3449 Added Name.isPrefixOf and getSuccessor.
In compare, support compare(int, int, Name, int, int).
* http://redmine.named-data.net/issues/3450 Added Name.Component.isSegment,
isSegmentOffset, isVersion, isTimestamp and isSequenceNumber.
* http://redmine.named-data.net/issues/3451 Added static Name.Component.fromSegment,
fromSegmentOffset, fromVersion, fromTimestamp and fromSequenceNumber.
* http://redmine.named-data.net/issues/3452 Added Interest.refreshNonce.
* http://redmine.named-data.net/issues/3152 In API callbacks, catch and log exceptions.
* http://redmine.named-data.net/issues/3355 In Producer.createContentKey and produce,
added an optional onError callback.
* http://redmine.named-data.net/issues/3590 Added MemoryContentCache.setInterestFilter.
* In IdentityManager, added prepareUnsignedIdentityCertificate, getAllIdentities
and getAllCertificateNamesOfKey.
* In KeyChain, removed getAnyCertificate and getAnyIdentityCertificate.
* Unit tests: In test_data_methods, added test_verify_ecdsa.
* Unit tests: Added test_link.
* Integration tests: In test_face_methods, added test_network_nack.
* Examples: Added test_sign_verify_data_hmac.

Deprecated
* In KeyChain, deprecated getIdentityCertificate. Use getCertificate.

Bug fixes
* http://redmine.named-data.net/issues/3589 Update examples face-status.proto.
* http://redmine.named-data.net/issues/1517 Use the onInterest callback only on registerPrefix success.
* Fix bug in encrypt/Schedule to solve problems when the black repetitive interval list is empty.
* In Producer, the produced data name should not use a rounded timestamp.

----------------------------

Changes
* Use the cryptography package instead of pycrypto. See INSTALL.md to update.
* In OSXPrivateKeyStorage, implemented generateKeyPair.

----------------------------

Changes
* Added the pyndn.encrypt package for the Group-Based Encryption Protocol, ported from
https://github.com/named-data/ndn-group-encrypt
* In Name, added support for hash(name). (A Name can be a dictionary key.)
* INSTALL: Removed unsupported OS X 10.8.4.
* INSTALL: Added OS X 10.11, Ubuntu 15.04 (64 bit) and Raspbian Jessie.

Bug fixes
* Fix bug in BasicIdentityStorage.getCertificate (Thanks Zhehao)
* http://redmine.named-data.net/issues/3342 In expressInterest, call onTimeout when there is no interest lifetime.

----------------------------

Changes
* In security, added KeyChain.createIdentityAndCertificate which returns the
certificate name, instead of the deprecated createIdentity which returns the
key name.
* Added AsyncTcpTransport and AsyncUnixTransport which use asyncio and do not
require the application to call processEvents.
* http://redmine.named-data.net/issues/3005 In Face.registerPrefix, added the
optional onRegisterSuccess callback.
* In ThreadsafeFace, for the constructors ThreadsafeFace(loop) and
ThreadsafeFace(loop, host, port) use AsyncTcpTransport or AsyncUnixTransport
which do not require the application to call processEvents.
* In ThreadsafeFace, remove support for stopWhen() since this requires a
processEvents loop which we want to avoid when using asyncio. The application
must stop the asyncio loop - see examples/test_get_async_threadsafe.py .
* In ThreadsafeFace, do not automatically run a processEvents loop since the
default AsyncTcpTransport and AsyncUnixTransport don't need it. (If your
application uses a different transport which does not use the asyncio loop,
then it needs to run a processEvents loop.)
* In ThreadsafeFace, don't automatically import it into the pyndn module since
asyncio is optional. To explicitly import it, use:
from pyndn.threadsafe_face import ThreadsafeFace
* In security ConfigPolicyManager, added load(input, inputName) to read
configuration rules from a string.
* In integration_tests, added test_registration_callbacks.
* In Face.registerPrefix, removed deprecated support to register with NDNx.
* In Interest, removed deprecated NDNx get/setScope.
* In ForwardingFlags, removed deprecated NDNx flags active, advertise, last,
local, tap and captureOK.
* Removed deprecated NDNx ForwardingEntry.
* Removed deprecated NDNx support for binary XML packets.
* In WireFormat, removed ENABLE_NDNX since all NDNx support is now removed.

Deprecated
* Deprecated KeyChain.createIdentity. Use createIdentityAndCertificate which
returns the certificate name instead of the key name.
* In Interest, deprecated get/setScope since it is for NDNx and NFD does not use it.

Bug fixes
* http://redmine.named-data.net/issues/2846 Self-signed cert name needs a version component.
* http://redmine.named-data.net/issues/2847 Lower-case "ksk-" in generated key name.
