Refer to http://redmine.ccnx.org/projects/ccn/versions/10 for more details on CCNx 0.6.1. * Improvements in interest forwarding (#100321) - Introduce new PIT data structure. Major revision to the way ccnd manages pending interests and improve way interest lifetimes are accounted. In the default strategy, preserve more of the ordering. This change removes the "hack" that allowed a few similar interests from the same source to pass through. This may affect applications that attempt to do hole-filling by resending interests prior to their timeout. For an example, see #100806. * TCP for libccn connections (#100760) - Make it possible to configure only TCP for local connect with -DCCN_LOCAL_TCP, as alternative to Unix-domain socket. This offers a way for devices with sandboxed filesystems such as within the Android context to get around the issue of sharing the UNIX domain file descriptor to connect to ccnd. * C implementation of text chat (ccnc) (#100787, #100790, #100791, #100793) - The *ccnc* utility is a text-based community chat program. Works with existing CCNx chat clients. * Improvements to Android CCNx Services stability (#100784, #100645, 100778, #100781) - Fixed a number of Android CCNx Services stability issues, including refresh updates to IP address in the UI when there an intent CONNECTIVITY_UPDATE is received, improve number of checks on service startup to print useful diagnostics to the user, and avoid problems that may prevent startup and proper functioning of CCNx. Added About menu item to get CCNx version information and added a Reset menu item to clear error states and clear startup/shutdown errors. * Issues Resolved: * Bug #100321: Improve efficiency interest suppression * Bug #100358: DataUtils getBytesFromFile and large files * Bug #100374: test.repo.Misc.java has bad logic * Bug #100645: Android CCNx service control - tapping "Start All" button multiple times quickly causes services to fail. * Bug #100682: CCNx tests uses grep flags unsupported by Solaris SunOS default grep but tests still succeed * Bug #100694: Fix ccntestloop stop command to more reliably clean up spawned processes * Bug #100711: Some gitignore files ignore too much * Bug #100728: HttpProxy tries to generate a keystore using a script that is no longer installed * Bug #100733: Binary decoder should increase its buffer size by larger increments at overflow * Bug #100744: CCN_GET_NOKEYWAIT flag to ccn_get() doesn't work * Bug #100746: Compiler erroneously detects uninitialized use of "cmd" in ccnsyncslice.c * Bug #100747: duplicate object file in csrc/ccnd/Android.mk * Bug #100748: small memory leak in ccnr when creating a new repository * Bug #100749: Warning in java repo due to method change * Bug #100750: Mac OS X 10.7 Lion users need clear instructions on what build pre-req tools need to be installed * Bug #100755: ccnd should hold unsatisfied scope0 interests * Bug #100758: SyncCacheEntryFetch can miss existing entries * Bug #100764: Java logging for FAC_SEARCH is broken * Bug #100765: BinaryXMLDecoder uses inappropriate algorithm for increasing decoder array sizes and the logging is broken. * Bug #100766: Null pointer dereference in ccnr * Bug #100768: fix potential NULL pointer deref and some uses of realloc() that could result in leaks * Bug #100769: name enumeration attempts to open mid stream * Bug #100770: versioning profile should be more defensive about what a valid version number is * Bug #100771: CCNxProtocol document description of FIB should not refer to destinations * Bug #100778: Android CCNx Service crashes on startup if CCNR "Unable to get repository policy object version" * Bug #100780: CCNx Android makefile should be posix compliant * Bug #100781: Android CCNx Service fails to start CCNR with "Unable to get repository policy object version" * Bug #100783: libccn code should be compiled with PIC on NetBSD * Bug #100784: Android CCNx Service displays loopback address on ICS even when other *faces are available * Bug #100788: exception in ccnlsrepo * Bug #100790: lned does not work properly on Mac OS X 10.5 * Bug #100791: ccnc input logic needs improvement * Bug #100792: MergeSecureKeyCacheTestRepo has initialization bug * Bug #100795: CCNDCacheManager.clearCache() issues too many interests * Bug #100796: Improve performance of ccnr rightmost-child operations * Bug #100800: ServiceDiscoveryProfile suffers from a race condition when publishing a local service key * Bug #100801: ccnr takes a segmentation fault if output fd closed due to other errors * Bug #100802: LatestVersionTest failures with new interest forwarding * Bug #100805: Memory leak in ccnr * Bug #100806: VLC plugin needs updates * Feature #100041: java tools should support a -h argument * Feature #100647: Default support for multiple architectures in MacOS X build * Feature #100701: A number of methods in ContentName have no general test coverage * Feature #100715: Provide interface for applications to set up Sync configuration slices and receive notification of (newly) sync'ed ContentObjects - in java library * Feature #100752: Side door for quickly adding content to a repo * Feature #100759: Extensions to HttpProxy * Feature #100760: C library needs method for connecting to ccnd via TCP in place of Unix-domain socket * Feature #100761: Implement deletion of btrees entries * Feature #100767: ccnsyncwatch should flush output after each line * Feature #100787: Provide a version of ccnchat that uses libccn * Feature #100793: ccnc man page needs to be updated to document new options * Support #100745: Update jenkins CI to use latest NDK/SDK for Android build project * Support #100757: Prepare for ccnx-0.6.1 release * Support #100779: CCNx Android build should explicitly set APP_PLATFORM and APP_ABI Changes between 0.5.1 and 0.6.0: -------------------------------- This highlights some important changes since the most recent numbered release. Refer to http://redmine.ccnx.org/projects/ccn/versions/9 for more details on CCNx 0.6.0. * A new varargs constructor has been added to ContentNames, a new Component class has been created, and ContentNameProvider and ComponentProvider interfaces have been provided to simplify the generation and minimize the overhead of building ContentNames. The Component class provides an immutable Component type, which encapsulates the component as a byte[] array, that is designed to hold static components to be passed into ComponentName constructors. In code, a Component should be used wherever possible in lieu of a static final byte[] array or a static final String, to avoid unnecessary copying. The ContentName varargs constructor, and the ContentNameProvider and ComponentProvider interfaces, allow classes to pass ContentNames and Components directly into the ContentName constructor. Most of the static component-related methods that previously existed under ContentName have been moved to the new Component class. The old methods remain available but are deprecated; it is recommended that code be changed to use the new static methods under Component. Please see Component, ContentName, and ContentNameProvider documentation for more information. * Issues Resolved: * Bug 100739 Provide installed command to manipulate Sync configuration slices * Bug 100738 Missing dependencies for csrc/lib/ccn_sync.c * Feature 100732 Tests should use C repo (repo2) instead of the old java one * Bug 100737 ccnr can fail to answer enumeration requests when interests are reordered * Bug 100725 The signing and verification code in the C library needs to conditionally compile elliptic curve (EC) features in case the crypto library is too old or has them compiled out. * Bug 100722 CCN C-library changes for must be brought up to date in Android * Bug 100470 Make in android directory with current tools leaves chaff * Bug 100726 Still some occasional deadlocks in VLC plugin * Feature 100729 VLC CCN plugin should provide access to prefetch offset via VLC option * Feature 100499 Unify ContentName constructors * Bug 100046 OpenSolaris build fails when cc is actually gcc * Bug 100724 Possible memory leaks of crypto allocated memory in merkle hash tree signature verification * Bug 100723 VLC plugin needs prefetcher * Bug 100719 User requested flush should actually flush out to network * Bug 100712 Java repo queue mismatch causes heap space problems * Bug 100704 Improve performance of flow control * Bug 100686 ccnlink parses its arguments incorrectly * Bug 100677 Several utilities do an incorrect close, causing a warning exception * Bug 100671 Netmanager thread can die mysteriously * Feature 100661 Improve logging in flow controller * Bug 100657 VLC plugin needs updates * Feature 100654 Input streams should have a true "blocking" mode * Bug 100608 CCNNetworkObjectTestRepo and other IO tests using the repo need to insure files have reached the repo before testing them * Feature 100574 Add a new logging facility (FAC_SEARCH?) for features like NameEnumeration and PathFinder * Bug 100528 VersioningProfile logging should be part of a facility * Bug 100717 Make loops in doc/manpages * Bug 100708 SyncNodeIncRC implementation is incorrect * Feature 100713 Refactor matching code so Exclude tests can be done separately * Bug 100716 fix couple of compiler warnings in ccn_sync.c * Support 100662 Setup CCNx Open Source project commit notifications via email + outbound tweets for all commits to projectccnx * Bug 100664 Remove ccnd/android_msg.c * Feature 100675 C/Java Libraries should be able to use different digest algorithms based on key type for signing * Bug 100676 Multiple registrations using ccn_set_interest_filter with same prefix do not work well * Bug 100688 Man page for ccntestloop * Feature 100690 Improve decoding performance * Bug 100691 Inconsistent formatting and use of asciidoc markup * Support 100692 Prepare for ccnx-0.6.0 release * Support 100695 Improve comments in ccnd * Bug 100696 Broken link in top-level README * Support 100697 Prepare for ccnx-0.5.2 release * Feature 100698 Add use of deltas to the RootAdvise protocol * Bug 100699 ccndc fails with Unable to create face in ccnx-0.5.1 on guest OS (fixed on 0.6.0) * Bug 100702 Intermittent test_repo_performance failures on slow platforms * Bug 100703 sync header files include other files only needed for implementation * Feature 100706 Integrate ccn_schedule events with ccn_run() * Feature 100707 Provide interface for applications to set up Sync configuration slices and receive notification of (newly) sync'ed ContentObjects * Feature 100709 Update schema and assign DTAG for new sync delta RootAdvise response Changes between 0.5.0 and 0.5.1: -------------------------------- This highlights some important changes since the most recent numbered release.

Refer to http://redmine.ccnx.org/projects/ccn/versions/5 for more details on CCNx 0.5.0. * Experience shows that many applications need local persistent storage. With the introduction of Repository-based synchronization, we now expect that most nodes will use a local Repository running alongside their local ccnd. As a result, we have changed defaults for storing content in a Repository so that those store operations target only the local Repository. * This release introduces an updated version of the Repository, with much improved scalability, that is capable of easily handling content collections many gigabytes in size. The new Repo, named ccnr, is written in C, has a disk-resident index, and has much higher performance, a smaller footprint, and faster start-up times. The startup and shutdown procedures have changed, as have some of the configuration options and the procedure for obtaining debug information. See doc/manpages/ccnr.1.html for more information about starting, stopping, using, and configuring Repo, Repo policies, and links to Repository protocol descriptions. While the Repo startup procedure has changed, it still must be started explicitly. * This release introduces Sync, a mechanism for CCN components to define collections of named data in Repositories, and for automatically synchronizing copies of identically defined collections in neighboring nodes. Sync is currently embedded in Repo, but will be made available separately in the future. Sync is started automatically when Repo starts unless configured otherwise. See the man page for SyncTest in doc/manpages/SyncTest.1.html for more information about Sync, and how to use SyncTest, a command line tool for testing Sync and creating collections. See doc/technical/SynchronizationProtocol.html for a description of the CCNx Create Collection Protocol and the internal protocol used by Sync Agents in neighboring nodes to keep their collections in synchrony. * The default for a RepositoryFlowControl has changed from allowing any Repository to answer to requiring only a local (connected to the same ccnd as the application) Repository. Direct users of the RepositoryFlowControl class can control the behavior through a (previously present) boolean in the constructor. Users of CCNNetworkObject can still control the local/non-local behavior through the SaveType REPOSITORY (allows non-local Repositories) and LOCALREPOSITORY. The SystemConfiguration option FC_LOCALREPOSITORY is unchanged and can still be used to force a local Repository. It cannot force permission to use a non-local Repository. ccnputfile/ccnputmeta has been updated to have an -allownonlocal option. The default behavior has also changed to require a local Repository if no command-line option is given. * Issues Resolved: * Feature 100112 Repo requires data storage in memory - this is unscalable *

For compatibility, it is still present by default, but further use should be phased out. The libraries have been changed to use local service discovery instead. The java option "org.ccnx.ping.timeout" is replaced by "org.ccnx.ccndid.timeout". (100187, 100188, 100189) * Responsibility for key saving has been shifted from the client library to repo. The Java API did not change but, as the result of a protocol change, the new library is not compatible with the old repo. (100288) * The Java library now uses TCP to communicate with ccnd, rather than UDP, to avoid problems and inefficiencies caused by UPD packet drops. (100078) * An explicit lifetime element has been added to Interest messages in order to give applications control of their timeouts. (100127) * FlowControl addNameSpace is now logged at info in the constructor. (100180) * ContentObjects are now created earlier to improve throughput by more efficiently balancing tasks between different threads. (100197) * Performance of writes has been improved by avoiding copies when the application is only calling write with integral multiples of the segment size. (100206) * The ccnseqwriter command has been installed and documented. (100227) * The traffic meters in the ccnd status display have been improved by metering activity in both directions, splitting out by content/interest, and showing rates as well as totals. (100256) * Android ccnChat uses a multicast interface by default, which does not work well in the emulator. To address this, an option to use a point-to-point face has been added to the configuration screen. (100267) * A sequence number has been added to each packet, encoded so that it is distinguishable from interest and content packets, that allows the receiving side to detect missing packets. (100275) * The CommonOutput doPut() method now returns the version written so command line utilities know the version name just created. In addition, logging in the while() loop in do_write has been isolated for improved performance. (100276) * java.library.path and -Xcheck:jni are now forwarded to daemon (100279) * Stream access for CCN segments has been added to the C library. (100283) * Support was added to the library for splitting an interest when the exclusion list gets too big. (100290) * The ccncat command was converted to use the ccn_fetch library in order to take advantage of pipelining. (100291) * Efficiency of flow controller was improved with more fine grained locking. (100299) * Counters were added to the CCNNetworkManager to facilitate debugging. (100300) * stats and clearstats signals were added to Repo. (100302) * A categorized statistics interface was added. (100306) * The efficiency of getRegisteredPrefix was improved. (100309) * An example of ccnb encoding of a data packet payload in Java was created. (100312) * The KeyDirectory class was split into a KeyDirectory base class and a PrincipalKeyDirectory subclass to make the KeyDirectory structure available for purposes other than Access Control. (100316) * The HTTP proxy demo code was added. (100322) * The performance of ContentName.fromURI() was improved. (100323) * Facility-based logStackTrace and logException methods were added. (100326) * Additional tests were added to verify that the InterestListener continues to auto-refresh the interest even when an InterestFilter for the same exact name as the InterestListener is closed on the same handle. (100327) * Performance was improved for ContentName.componentParseURI(). (100331) * A StatusResponse message type was added to allow such things as an error response for prefix registrations. (100341) * CCN_FORW_TAP was added to repo prefix registration. (100342) * Repo no longer unnecessarily uses multiple Interest handlers. (100343) * Implemented more useful interactions between forwarding flags. In particular, the definition of CCN_FORW_TAP includes the provision that it is not subject to capture, and flags that have an effect on the prefix as a whole (including CCN_FORW_CAPTURE) do not change behavior depending on the setting of CCN_FORW_ACTIVE. (100345) * Synchronization in InterestTable was improved. (100353) * CCNNetworkManager was updated to limit thread creation for handlers. (100354) * The following enhancements were made to ccntestloop: (100356) - Accumulate testout directories outside of javasrc - Read config via script - Handle start/stop/restart/status verbs - All output to files (when using start verb) - Handle kill better - Record pid - Allow configuration of port range * Instances of ccnd are now allocated dynamically to allow more testing flexibility. (100363) * The log command in utilities now sets the level for all facilities. (100364) * Java interest handling code now has a log facility. (100366) * A Java library routine that sets the ccnd caches stale has been created to ensure that readbacks are actually from repo and not from the cache. (100367) * Logging between CCNNetworkManagers and CCNNetworkChannel has been made unique. Note that there is no relationship between CCNNetworkManager ids and Channel ids. (100432) * openssl for Android builds are now based on 1.0.0d. (100438) * ccnChat was updated to publish its keys under the chat channel namespace. (100439) * A testing framework was added to make assertions in child threads catchable. (100454) * ccnd is now able to sense the presence of other end (i.e., to distinguish between loss of connection and simple lack of incoming data). (100461) * Added a junit to check that prefixes are as expected in the FIB when doing localRepoSync. (100464) * [Support] Instructions in the README for ccnchat were enhanced. (100338) * [Support] Description of forwarding flags used in ccn_set_interest_filter_with_flags (100467) * Issues Resolved: * Bug 100091 Long running java applications can't recover from ccnd restart * Bug 100094 infinite loop building wireshark plugin * Bug 100196 SecureKeyCache debug output incorrectly describes output * Bug 100199 Incorrect values of DEFAULT_DIGEST_LENGTH * Bug 100201 Missing

between 0.2.0 and 0.3.0: -------------------------------- * Android support. This release includes support for Android 2.1 platform development. (100246) * Self-registration protocol. This functionality allows clients to register the prefixes for interests they wish to receive. (100071, 100072, 100073) The old form of self-registration (operating on the prefix ccnx:/ccnx/reg/self) has been removed. (100114) * Prefix registration on incoming connections. For a ccnd to act as a hub (as in a hub-and-spoke configuration) there needs to be a way to get prefix registration on incoming connections. Eventually, routing agents will perform this operation. This implementation retains the 'flooding' behavior of earlier releases for selected prefixes. NOTE: this requires explicit additional configuration via CCND_AUTOREG setting. (100225) * ccnd_destroy(). This functionality provides improved flexibility beyond exit() to free up all resources. (100051) * destroyface(). Implementation of the previously documented functionality. (100068) * ccnChat improvements: * This release changes ccnchat() to display user friendly names instead of partial key digest (100214). * ccnchat is refactored to be re-usable, called from the ccnChat.java GUI and the ccnChatNet.java module. It is also available on the command line: bin/ccnchat -text namespace (100234). * ccnchat now verifies the first packet: if verification fails, it rejects that version and looks for a later one. (100163) * Performance improvements in CCNNetworkObject. This release includes a revamp of the network objects including a few major API changes (100088): * Write constructors create flow controllers at construction time, leaving lazy creation for read constructors. Write constructors make/take a FC start listening for interests for their base name immediately (if they know it) * The repository is the default behavior for network objects, rather than "raw". * Support a customized DTAG dictionary. This release changes the ccn_ccnbtoxml and ccn_xmltoccnb tools so that a customized dictionary could be provided at runtime; this enables the tools to be used for protocols that live outside of the CCNx base. (100129) * Key naming. This release defines the KeyProfile (100055) and uses it for key ids, guids, and other component types (100131). This change is incompatible with existing header naming; backward compatibility is enabled by default. * Still-pending interests behavior. This release changes how ccnd keeps track of the outbound faces for an interest. In the new representation, pe->outbound is kept in send order instead of the reverse, and the new index pe->sent is advanced as the faces are used. This leaves a trail of the faces that have been used already, giving more flexibility in altering the outbound list to the right of pe->sent. (100103) * Repository publishes public key. Any app that wants to depend on name enumeration, checked writes, etc, needs to be able to validate who a repository is. This release includes publishing the repository key using localhost key discovery, making it easier to configure where the repository publishes its key. (100144) * javax.xml streams. Removed as many dependencies as possible such that their use is isolated to the text xml encoder/decoder. (100053) * Access control to stream/object encryption. The access control system allows you to assign keys to content/recipients, and automatically retrieve keys. In this release, the output and input streams (and the network objects that use them) retrieve keys and automatically encrypt content. (100063) * Bulk import to repo. This release supports bulk importing of a sequence of content objects (data) from a file in a single operation. The file must contain content objects in wire format. The repository can incorporate the file as a new storage file directly if that is compatible with its store format. (100210) * Local repo save and save-type override. This release supports objects and streams to be written to a local (same device) repo (100213). In addition, it implements an environment variable to allow objects to be saved in a local repository even if they were generically coded to be written to any/multiple repos (100223). * Localhost tcp peers considered friendly. Now ccnd considers tcp connections from localhost to be "friendly" and only considers incoming localhost udp traffic to be "friendly" if it starts out with a heartbeat packet. (100120) * Next-neighbor scope. For applications that want to be assured that they are communicating only with immediately neighboring machines, this release defines a new allowed Scope value in the interests. (Scope = 2) (100123) * EnumeratedNameList methods. This release includes methods to replace deprecated methods in EnumeratedNameList. (100230) * Capture-prefix flag. In the FIB, if a shorter registration has the CCN_FORW_CHILD_INHERIT set, a registration for a longer match can't be used to prevent the interest from being propagated. This release includes a flag that can be applied on the longer prefix to override the effect of CHILD_INHERIT on the shorted prefixes. (100116) * Prefix registration using a ContentName. In this release, the PrefixRegistrationManager accepts a ContentName object for the prefix to register in addition to a URI encoded string. (100186) * Multicast traffic. ccnd is now able to set up multicast using the standard ccnd socket. This involved changing the way ccnd keeps track of the sending side when the multicast cannot be done using a single socket. Instead of keeping 2 fds per face, ccnd now keeps 1 fd and a faceid to be used for datagram sends. Because the faceids are never reused, the bookkeeping becomes simpler. A user-visible side effect of this is that there are now faces visible in the status display that are not used for ccnx traffic. These represent the stream listeners and the datagram sockets that are shared among other faces. They carry the face flag CCN_FACE_PASSIVE. (100135) * Timeouts. Timeouts are now settable for situations which may require longer than usual timeouts. (100153) * Key cache. You can set a variable to control whether or not to save/load the key cache. This variable is set to false by default. (100154) * ccn directory location. libccn now uses the CCNX_DIR environment variable. (100026) * Compatibility with openssl-1.0.0beta4 and following. ccn is now compatible with the STACK_OF macro and related changes in the OpenSSL code. (100095) * Local service discovery protocol. This release introduces the CCN_FORW_LOCAL forwarding flag. The presence of this flag in a FIB entry marks the namespace as local to the host (more specifically, to apps directly connected to the ccnd in question). This is in support of implementing a host-local namespace useful for local service discovery. The ccnd does its best to make sure that content within such a namespace comes only from local apps, and is delivered only to local apps. There is one known flaw in the current implementation, namely that an off-machine attacker could cause a stale content object in the local space to become fresh again. To do this, the attacker would have to already have a copy of the C.O., which was supposed to be machine-local. Thus there must also be some collusion going on for this to happen. (100134) * Logging changes. This release includes a number of changes to logging configuration and content: * Log messages use the facility name for the logger name instead of org.ccnx.ccn.CCNHandle for everything. This change makes it easier to find specific facility related messages in large log files. The DEFAULT_APPLICATION_CLASS must be a prefix in the Logging namespace of the other loggers so that they inherit the handlers added to it. (100185) * ccntestloop now keeps logs for failed runs and the last few successes, and deletes the rest. (100220) * This release allows you to reduce the number of messages produced by ccndstart.sh: specify CND_LOG for ccndstart so ccndstart will discard messages about stuffing the cache. (100069) * Stream open/close events are now logged. (100181) * FAC_USERxx facility names include more complete logging. (100183) * Many small bug fixes to address issues with tests. * Clarity and documentation: The RepositoryDataListener method and variable names better reflect the current functionality (100216); there is now a manpage entry for ccndstatus (100232). * Interests. Bugs fixed for interest handling behavior include: * Repo generating new responses to ccnls interests (100102) * Java library sending explicit AnswerOriginKind in interests, using the default value (100106) * Change default behavior for ccnput command to wait for interest (100117) * ccnd occasionally retransmits interest (spurious interest re-expression fixed) (100121) * ccnd can occasionally fail to remove interests from prefix table (100226) * Pipeline fixes. The release includes the following fixes in the area of pipelining data segments: * MetadataProfile getLatestVersion() will no longer append a version based on the current time if there is no version found in the network in the passed-in timeout (100233) * Pipeline code sent the first segment interest when version was not known yet (100141) * Pipelining initialization problem: Some timing circumstances caused pipelining to hang (100194) * Repo pipelining now issues new interest before processing received content failed verification and advancing the pipeline (100221) * Streaming fixes. The release includes the following fixes in the area of streaming data: * CCNAbstractInputStream now uses Long instead of String for readerReady (100204) * NullOutputStream now provides byte string methods to reduce call overhead (100212) * Input streams now call close() and close() shuts down pipelining and closes any headers that might be retrieved (or attempted). (100235) * ccn_resolve_version(). The exclude filter is now fixed to always return the highest version; ccn_resolve_version() returns quickly if a version is already present. * Repo FreshnessSeconds. This release increases the FreshnessSeconds on repository startWrite() response to 12 sec from 1 sec so transactional data are not held for a long time in ccnd. (100139) * Issues Resolved: * Bug #100012 java ContentObject code calculates digest on content only * Bug #100018 content explorer takes exception when there is no repo * Bug #100044 ccnget -c returns incorrect status * Bug #100061 ccnd Exclude processing needs performance improvement * Bug #100066 unsolicited content should not cause ccnd to toss good content * Bug #100074 ccn_initkeystore.sh fails if $USER is not set * Bug #100076 Use of $$ in csrc/tests/test-* considered harmful * Bug #100085 ccnchat doesn't work with java 1.5 by default * Bug #100090 Java ContentType definition for ENCR does not match the one in ccn.h * Bug #100093 seg fault in ccndc * Bug #100098 ccnchat gets illegalArgumentException for empty line * Bug #100099 Implement unreg action in ccnd - unregister prefix * Bug #100108 Some system loggers can't handle log parameters * Bug #100109 Java prefix registration should not use interest nonces * Bug #100110 ccnd blocks when attempting a connect * Bug #100113 ccnd does not allow clearing of flags in FIB * Bug #100124 Logging can cause repository to deadlock * Bug #100126 Java header creation inconsistent with ccnx.xsd header schema * Bug #100130 ccnsendchunks / ccncatchunks block size problems * Bug #100136 Nonce-based interest suppression in ccd is incomplete * Bug #100137 The handling of responses from the ccnd internal client does not cope with multiple messages in the buffer, causing them to be discarded. * Bug #100151 All Repo related logging should use FAC_REPO * Bug #100176 EnumeratedNameList.getNewData only gets data once * Bug #100179 ServiceKeyDiscoveryTest hardwires data writing into "." * Bug #100184 getLatestVersion resets the attempt time * Bug #100191 Java ForwardingEntry object validation is incorrect * Bug #100200 The constructor for PublisherPublicKeyDigest(String) should raise an exception if the string is not a proper base64Binary encoding. Both that and the PublisherPublicKeyDigest(byte []) constructor should probably raise an exception if the input is too long, rather than silently truncating. * Bug #100208 It is possible for WaitForPutDrain to go into an endless loop rather than throwing an exception when the buffer hasn't been drained correctly. * Bug #100231 Fix ccndc delete command to correctly remove prefix registration rather than attempting to destroy a face. * Bug #100240 Java library missing some forwarding flag definitions * Bug #100244 CCNNetworkManager code should log using FAC_NETMANAGER facility * Bug #100252 Reduce number of writing threads in network manager Changes between 0.1.2 and 0.2.0: -------------------------------- NOTE: 0.2.0 introduces some changes to the core CCNx protocol, most notably a change in the definition of ephemeral digests. * The implicit digest component used as the last component in the name of a ContentObject, used in Links and Exclude filters, now use the digest of the entire encoded ContentObject, rather than merely the digest of the CO's content field. This allows exclusion of inadvertent or malicious traffic with the same name and content but different signing information from the intended traffic. Described in doc/technical/DigestComponent.txt * Removed dependency on javax.xml.streams. Replaced with stream-based XML Pull parser as implemented in the kXML library (http://kxml.sourceforge.net/). This removes the JDK 1.5-specific requirement for JSR 173 jars; JDK 1.5 users can delete jsr173.jar and jsr173_ri.jar from their lib directories. * Repositories now have their own key pairs, rather than using the user's default key. This will enable policy-related communication with the repo and more sophisticated, multi-repository name enumeration protocols. * Implementation of the registration protocol, which allows clients to register with ccnd the prefixes for Interests they wish to receive, is well under way (see issues #100071, #100072, #100073). Until this code is stable, we will retain the default Interest flooding behavior. * Initial version of Java-based registration control client, ccndcontrol, analogous to ccndc. * Added new ccnFileProxy application, and start script bin/ccnfileproxy; this proxies a specified portion of local file space to CCNx. Note that the proxy currently does not respect access controls, and will make all files it can read available. * Logging cleanups and improvements throughout. * Bump CCN_API_VERSION to 2000. * Make a more palatable C API for signing content objects; see ccn_sign_content(...). * Fix -v handling for ccnputfile. * Remove troublesome uses of $$ in csrc/tests/test_* (Bug #100076) * Fix ccn_initkeystore.sh to not rely on $USER. Use the id command instead. * Start to make configuration settings more robust to platform variations; improved options for controlling KEYSTORE_DIRECTORY, CCN_DIR and username. * Fix ccnd to verify the signatures in face management and registration requests. * Added a C library mechanism for obtaining ccndid, needed by self-registration. * Allow ccndsmoketest to send zero-length datagrams if so instructed. * Remove unused ccn_signed_info_create_default() from API. * Add vlc parameters to control: ccn-fifo-maxblocks -- the maximum number of blocks held in the FIFO ccn-fifo-blocksize -- the size of blocks queued in the FIFO * Improved vlc plugin to use data prefetching, and attempt reconnection when disconnected from ccnd. * Make the XML jar file a property so it can be overriden on the command line if using different library. * Cleanup, bug fixes and additional tests for access control code. * Many small bugfixes to address issues with tests. * Issues Resolved: * Feature #100010 Change implicit digest component * Bug #100012 java ContentObject code calculates digest on content only * Bug #100020 repo policy files should be able to span multiple ContentObjects * Bug #100022 hashtb.c needs the delayed finalization case to be implemented Was included in 0.1.2. * Bug #100031 ccnd should check for AF_UNIX * Bug #100034 CCNWriter doesn't take preexisting Interests * Bug #100048 perror calls in ccnd should use ccnd_msg instead * Bug #100050 Refactor ccnd for improved flexibility in file locations and logging Added CCN_LOCAL_SOCKNAME and CCND_KEYSTORE_DIRECTORY variables. * Feature #100050 Refactor ccnd for improved flexibility in file locations and logging * Feature #100053 remove dependency on javax.xml streams * Feature #100054 repository needs its own keys * Feature #100066 unsolicited content should not cause ccnd to toss good content * Feature #100067 Refactor ccnd keystore directory * Feature #100068 Implement destroyface in ccnd * Feature #100069 make ccndstart.sh less chatty * Feature #100071 Self-registration protocol in ccnd * Bug #100076 Use of $$ in csrc/tests/test-* considered harmful * Bug #100077 Please write some more code here (reduced debugging output) * Bug #100079 ccnputfile does not write any segments for zero-length files * Bug #100083 ccnd not listening to both ipv4 and ipv6 tcp addresses on Linux Known issues: * intermittent Java test failures, usually around failure to retrieve segments; there is work in process that we expect will fix most of these * intermittent failures of the C test test_destroyface * intermittent JVM crashes on Java 1.5 on OSX Leopard * the default ant/jUnit on Solaris 11 doesn't work; you need to copy over the ant-junit.jar from /usr/grails/1.0.3/ant/lib/ant-junit.jar to /usr/share/lib/ant/ant-junit.jar Changes between 0.1.1 and 0.1.2: -------------------------------- NOTE: ccnChat will not inter-operate with older versions due to fix for #100030. * Changes to crypto implementation for compatibility with older versions of BouncyCastle and configurations with varied crypto support. Also improved handling of crypto providers. * Added stopall argument to ccn_repo command to stop all running repos on machine. * Turned off ccnd message about heartbeats by default (use CCND_DEBUG=128 to get these messages back). * Fixed ccnput to allow name components after the version marker, generate FinalBlockID where appropriate. * Added support for file segmentation convention to ccncatchunks2. * Centralized timeout definitions in Java library to SystemConfiguration. * Improved VLC plugin, incl. using name "ccnx", supporting versioned files. * Small improvements to ContentExplorer such as option to save a file to filesystem. * Enlarged time scale for C test_scale to reduce chance of spurious failure. * Added scripts for running experiments with content distribution. * Handle null return from readLine for binary decoding in Java library (#100025). * Improvements to CCNFilterListener support in Java library (#100027). * Improvements to repo performance (#100017) * Issues Resolved: * Bug #100009 Repository makes duplicate data requests. * Bug #100014 Update code to use IANA allocated port. Replaced temporary port number with registered ccnx port number 9695. See http://www.iana.org/assignments/port-numbers * Bug #100015 ccndc only processes last command in config file. * Bug #100016 Repo should not process each piece of content as a potential policy update. * Bug #100019 Incorrect marker byte used for enumeration, repo protocols. * Bug #100021 Repo should have a simple way to specify prefix on startup. * Bug #100023 c tests minsuffix and contenthash failing. * Bug #100024 BasicKeyManager passes null to generateConfigurationException. * Bug #100030 ccnChat/default network string shouldn't use Java serialization. Converted Java CCNStringObject to use UTF-8 string encoding. * Bug #100039 ccn.h should have an API version identifier. * Introduce Java ContentEncodingException and use IOException rather than using XMLStreamException widely. * Bug fixes and additional tests for AccessControlManager. * Bug fixes for name enumeration. * Improvement of internal state handling in BloomFilter.java. * Adjustments to logging level of some Java tests. * Reorganization of some Java tests to help track down intermittent failures. * ContentExplorer checks for presence of VLC plugin. * Bug fixes for Java test CCNNetworkObjectTestRepo. * Build fixes for Mac OS X 10.6 * Added optimization for Java network objects based on immutable values. * Fixed broken parameter check in ccndc. * Merged specifications of infinite timeout values for Java API. * Improvements to Java CCNFlowControl and creation of simple in-memory server to serve keys. * Improved exception handling for Java network objects. * Cleaned up XML handling for repo policy files. * Added new support for local repo write unit tests. * Eliminated timersub from signbenchtest.c for portability. * Improved interest reexpression in Java library. * Minor refinements to Java log messages. * Revisions to Java documentation. * Minor improvements to C library. Changes between 0.1.0 and 0.1.1: -------------------------------- * Fixed timing window bug in RepositoryFlowControl affecting repository writing. * Minor improvements to logging in Java library. * Minor changes in build/packaging, Java import list. * Fixed varargs handling in C library for C99 compliance and to fix operation on FreeBSD/amd64. * Auto-generated documentation has been improved, particularly in some Java classes. * ccncatchunks2 now produces a summary output. * org.ccnx.ccn.profiles.access.AccessControlProfile.principalInfoToNameComponent now takes a PrincipalInfo object as input rather than individual values from such object. * The logging level for the Java end-to-end test has been increased to help track down intermittent bugs. * Bugs have been fixed in org.ccnx.ccn.test.io.content.CCNNetworkObjectTest, CCNNetworkObjectTestRepo. * ccnls now prints a usage message if not given useful input (#100004). * Java ContentName now has additional convenience constructor. * New naming structure for test data has been introduced to use test-specific, timestamped names for unit tests. This is not yet fully implemented in test suite. * Java Eclipse project name is now CCNx-Java, and the README now explains how to import the Eclipse projects from files in the distribution to get the cross-references. * The BinaryEncoding and SignatureGeneration technical documentation has been slightly repaired. * Java lib CCNAbstractInputStream now decrypts content objects as a unit, improving random access performance for streams without significant security penalty.
