Several old classes whose instances can be shared by multiple request exchanges have been replaced by immutable equivalents. The 4.3 branch also contains performance optimizations such as reduced TCP packet fragmentation and more efficient lease / release operations for pools of persistent connections on the client side. This release also includes all fixes from the 4.2.x release branch. Users of HttpCore 4.2 are encouraged to upgrade.

Contributed by Ignat Alexeyenko * Blocking connections do not clean session input buffer when closed (input data from a read operation may still remain in the buffer if the connection is re-opened). Contributed by Oleg Kalnichevski Release 4.2.5 ------------------- This maintenance release fixes a number of bugs found in NIO components since 4.2.4. We advise users of HttpCore NIO of all versions to upgrade. This is likely to be the last release in the 4.2.x branch.

Contributed by Oleg Kalnichevski Release 4.3-ALPHA1 ------------------- This is the first release from the 4.3.x release branch. The main focus of the 4.3 release series is streamlining of component configuration and deprecation of the old configuration API based on HttpParams in favor of constructor based dependency injection and plain objects for configuration parameters. We are kindly asking all upstream projects to review API changes and help us improve the APIs by providing feedback and sharing ideas on dev@hc.apache.org. This release also includes all fixes from the stable 4.2.x release branch. Release 4.2.3 ------------------- This maintenance release fixes a number of bugs and found since 4.2.2 including a major bug in the NIO module that can cause an infinite loop in SSL sessions under special circumstances when the remote peer terminates the session in the middle of SSL handshake. Please note this issue does not affect blocking I/O components used by HttpClient. We advise users of HttpCore NIO of all versions to upgrade. Change Log ------------------- * [HTTPCORE-319, HTTPCORE-322] Non-blocking SSLIOSession can enter an infinite loop under special circumstances when the remote peer terminates the session in the middle of SSL handshake.

Contributed by Oleg Kalnichevski Release 4.2-ALPHA2 ------------------- This is the second ALPHA release of HttpCore 4.2. This release comes with completely redesigned and rewritten asynchronous protocol handlers. New protocol handling API used in conjunction with connection pooling components introduced in the previous ALPHA release is expected to make development of asynchronous HTTP client agents and HTTP proxies easier and less error prone. Sample application shipped with the release include an example of an HTTP file server capable of direct channel (zero copy) data transfer and an example of a non-blocking, fully streaming reverse proxy. We are kindly asking existing and prospective users of HttpCore to review and try out the new protocol handlers and give us feedback while the 4.2 API is still not final. If no major flaws are discovered the 4.2 API is expected to be frozen with the next BETA release. Please note that new features included in this release are still considered experimental and their API may change in the future ALPHA releases. This release also marks the end of support for Java 1.3. As of this release HttpCore requires Java 1.5 for all its components.

This release mainly improves the documentation and fixes a few minor bugs reported since the previous release. HttpCore now comes with a complete tutorial presenting an in-depth coverage of the API. HttpCore is a set of low level HTTP transport components that can be used to build custom client and server-side HTTP services with a minimal footprint. HttpCore supports two I/O models: blocking I/O model based on the classic Java I/O and non-blocking, event driven I/O model based on Java NIO. The blocking I/O model may be more appropriate for data intensive, low latency scenarios, whereas the non-blocking model may be more appropriate for high latency scenarios where raw data throughput is less important than the ability to handle thousands of simultaneous HTTP connections in a resource efficient manner. * [HTTPCORE-180] Fixed NPE in standard I/O event dispatchers when IOEventDispatch#disconnected fires before the session was fully initialized (IOEventDispatch#connected was not called).

Contributed by Oleg Kalnichevski * [HTTPCORE-172] Added #close() method to SharedInputBuffer and SharedOutputBuffer. The purpose of the new method is to close the buffer in case of normal / orderly termination of the underlying HTTP connection. Use #shutdown() method to force-close the buffer in case of abnormal / exceptional termination of the underlying connection. Contributed by Oleg Kalnichevski * [HTTPCORE-170] Fixed race condition in SharedOutputBuffer. Contributed by Jason Walton * [HTTPCORE-169] Fixed bug causing connecting I/O reactors to shut down due to ClosedChannelException if a pending session request is cancelled before the new channel has been registered with the selector. Contributed by Anders Wallgren * [HTTPCORE-167] Fixed handling the end of stream (EOF) condition in the #isStale() check of blocking HTTP connections. Contributed by Oleg Kalnichevski * [HTTPCORE-166] NIO reactors now maintain an audit log of fatal exceptions, which can be used to examine the cause and problems experienced during the shutdown process. Contributed by Oleg Kalnichevski * [HTTPCORE-165] Improved handling of CancelledKeyException in I/O reactors Contributed by Oleg Kalnichevski Release 4.0 Beta 2 ------------------- The second BETA version of HttpComponents Core has been released.

Perera * [HTTPCORE-150] Entity implementation that serializes a Java object Contributed by Andrea Selva * [HTTPCORE-157] ChunkedOutputStream#flush() now behaves consistently with the specification of OutputStream#flush(). Contributed by Oleg Kalnichevski * [HTTPCORE-147] Fixed handling of requests with partially consumed content in ThrottlingHttpServiceHandler. Contributed by Oleg Kalnichevski * [HTTPCORE-92] ChunkEncoder splits input data larger than available space in the session output buffer into smaller chunks instead of expanding the buffer. Contributed by Andrea Selva and Oleg Kalnichevski * [HTTPCORE-149] I/O reactors now count period of inactivity since the time of the last read or write operation. Previously only read operations resulted in timeout counter reset. Contributed by Oleg Kalnichevski * [HTTPCORE-148] Improved asynchronous server and client HTTP protocol handler implementations.

Contributed by Steffen Pingel * [HTTPCORE-102] Exceeding of maximum line length limit detected late Contributed by Steffen Pingel * [HTTPCORE-21] Transport and connection metrics Contributed by Andrea Selva and Oleg Kalnichevski * [HTTPCORE-91] new interceptor RequestDate, renamed constants in protocol.HTTP Contributed by Roland Weber * [HTTPCORE-90] Version detection based on build-time properties Contributed by Oleg Kalnichevski and Roland Weber * [HTTPCORE-88] Added convenience methods to HttpRequestInterceptorList, HttpResponseInterceptorList interfaces Contributed by Andrea Selva * [HTTPCORE-89]: Fixed bug in DefaultConnectingIOReactor causing incorrect handling of local (immediate) connections on some platforms (affects Sun Solaris 2.9 / Sparc and likely other Solaris 2.x platforms) Contributed by Sam Berlin Release 4.0 Alpha 5 ------------------- The fifth ALPHA version of HttpComponents Core has been released. This release delivers a number of incremental improvements across the board in all modules and adds several performance oriented features such as ability to transfer data directly between a file and a socket channels. HttpCore is almost fully feature complete now and we are likely to freeze the public APIs as of next release (BETA1). * [HTTPCORE-87] RuntimeExcpetions thrown in I/O worker threads are now correctly propagated to the I/O reactor. Contributed by Oleg Kalnichevski * [HTTPCORE-84]: Removed DateUtils/DateParseException from core. Contributed by Roland Weber * [HTTPCORE-63]: Made I/O select interval configurable for all default I/O reactor implementations. Contributed by Oleg Kalnichevski and Anders Wallgren * [HTTPCORE-82]: Revised linking of HttpParams to reduce potential for misuse. Method #setDefaults() removed from the HttpParams interface. Contributed by Roland Weber * [HTTPCORE-81]: Maximum line length and maximum header counts parameters are now correctly enforced in both base and NIO modules. Fixed maximum line length check when parsing folded header lines. Contributed by Steffen Pingel * Added HTTP client handler implementation that allocates fixed size content buffers upon initialization and is capable of throttling the rate of I/O events in order to make sure those content buffers do not get overflown. Contributed by Oleg Kalnichevski * [HTTPCORE-76]: Added IOSession#shutdown() method intended to force-close I/O sessions (primarily needed to terminate hung SSL connections). Contributed by Sandeep Tamhankar * [HTTPCORE-78]: Added ByteBufferAllocator interface that can be used to apply different ByteArray allocation strategies to session and content buffers. Use heap bound implementation for short-lived or variable in length (requiring frequent content re-allocation) buffers. Contributed by Steffen Pingel * [HTTPCORE-77]: The result of CharsetDecoder#decode() and CharsetEncoder#encode() was not checked for errors resulting in an infinite loop in SessionInputBuffer#readLine() and SessionOutputBuffer#writeLine() when malformed characters were processed. Contributed by Steffen Pingel * [HTTPCORE-71]: HttpParams can be copied. Contributed by Roland Weber * [HTTPCORE-75]: DefaultNHttpServerConnection and DefaultNHttpClientConnection now correctly terminate the underlying I/O session when closed. BufferingHttpServiceHandler now correctly applies connection keep-alive strategy when sending a response with no content body. Contributed by Steffen Pingel * [HTTPCORE-73]: Fixed bug preventing NHttpServiceHandler#responseReady and NHttpClientHandler#requestReady events from being fired if the HTTP message has no content body. Contributed by Steffen Pingel * [HTTPCORE-67]: Improved event listener interface Contributed by Oleg Kalnichevski * [HTTPCORE-43]: Support for FileChannel#transferFrom() and FileChannel#transferTo() methods. Direct coping from and to FileChannel is expected to improve performance of file bound operations Contributed by Andrea Selva * [HTTPCORE-66]: Fixed handling of HTTP HEAD methods Contributed by Steffen Pingel and Oleg Kalnichevski * [HTTPCORE-58]: NIO HTTP connections changed to throw checked ConnectionClosedException instead of unchecked IllegalStateException when an attempt is made to perform an I/O operation on a closed conection Contributed by Oleg Kalnichevski * [HTTPCORE-56]: DefaultConnectingIOReactor no longer terminates due to a CancelledKeyException, if a session request gets canceled before selection key is fully initialized. Contributed by Oleg Kalnichevski Release 4.0 Alpha 4 ------------------- The forth ALPHA version of HttpComponents Core has been released. The ALPHA4 release fixes a number of bugs and adds a number of improvements to HttpCore base and HttpCore NIO extensions. HttpCore NIO can be used to build HTTP services intended to handle thousands of simultaneous connections with a small number of I/O threads. This release also introduces NIOSSL extensions that can be used to extend HttpCore non-blocking transport components with ability to transparently encrypt data in transit using SSL/TLS protocol. * [HTTPCORE-49]: DefaultConnectingIOReactor can now correctly handle unresolved socket addresses. It no longer terminates with the UnresolvedAddressException runtime exception. Contributed by Oleg Kalnichevski * [HTTPCORE-42]: Added server-side API for the expectation verification. Improved support for the 'expect: continue' handshake in HttpCore and HttpCore NIO. Contributed by Oleg Kalnichevski * [HTTPCORE-26]: Added SSL support for HttpCore NIO. Contributed by Oleg Kalnichevski * [HTTPCORE-40]: API classes no longer reference impl classes in module-main. Contributed by Roland Weber * [HTTPCORE-39]: Refactored HttpStatus, spun off [English]ReasonPhraseFactory. Contributed by Roland Weber * [HTTPCORE-32]: HttpRequestInterceptorList, HttpResponseInterceptorList Contributed by Roland Weber * [HTTPCORE-38]: Packages nio.impl.* are now impl.nio.*, same for examples. Contributed by Roland Weber * [HTTPCORE-27]: I/O reactors can now accept a thread factory as an optional parameter. Contributed by Oleg Kalnichevski * [HTTPCORE-36]: Fixed #setHandlers() method and matching of request URIs with a query part in HttpRequestHandlerRegistry Contributed by Oleg Kalnichevski * [HTTPCORE-28]: DefaultConnectingIOReactor now maintains a queue of connect requests and registers new sessions with the selector on the I/O thread. Contributed by Oleg Kalnichevski * [HTTPCORE-29] DefaultConnectingIOReactor changed to ensure IOExceptions are correctly propagated to the caller, if an exception is thrown while initializing a newly connected socket. Contributed by Oleg Kalnichevski * [HTTPCORE-24] Fixed bug in non-blocking connection implementations, which prevented the session buffer from being correctly flushed when the content coding process has been completed. Contributed by Oleg Kalnichevski * [HTTPCORE-23] Fixed threading bug in DefaultConnectingIOReactor. Contributed by Asankha C. Perera Release 4.0 Alpha 3 ------------------- The third ALPHA version of HttpCore has been released. The ALPHA3 release includes a number of API optimizations and improvements and introduces a set of NIO extensions to the HttpCore API. NIO extensions can be used to build HTTP services intended to handle thousands of simultaneous connections with a small number of I/O threads. * [HTTPCORE-15] Provided a interafce to access IP address of the local and remote end points. Contributed by Oleg Kalnichevski * [ HTTPCORE-14] Scheme, SocketFactory and SecureSocketFactory moved to HttpClient. Decoupled HttpHost and Scheme. Contributed by Oleg Kalnichevski * [HTTPCORE-13] Refactored HttpProcessor interface and related impl classes Contributed by Roland Weber * [HTTPCORE-11] Client connection interface no longer defines a specific method to open a connection. HTTP connections can now represent any abstract I/O transport such as those based on NIO API. Contributed by Oleg Kalnichevski * [HTTPCORE-10] Non-blocking (async) client side I/O transport based on NIO. Contributed by Oleg Kalnichevski * [HTTPCORE-9] Non-blocking (async) server-side I/O transport based on NIO. Contributed by Oleg Kalnichevski * [HTTPCORE-7] ConnectionReuseStrategy interface changed to allow access to the HTTP execution context. Contributed by Roland Weber * [HTTPCORE-6] Header implementation allowing for performance short-cuts when serializing and deserializing HTTP headers. Contributed by Oleg Kalnichevski * [HTTPCORE-5] Header, HeaderElement, NameValuePair, RequestLine, StatusLine, HttpVersion changed to interfaces. API no longer contains any parsing and formatting code and does not imply any specific physical representation of HTTP messages and their elements. Contributed by Oleg Kalnichevski Release 4.0 Alpha 2 ------------------- This is a maintenance release that mostly fixes minor problems found since the previous release. The upstream projects are strongly encouraged use this release as a dependency while HttpCore undergoes another round of reviews and optimization in the SVN trunk Change Log: --------- * [HTTPCORE-4] optional header and line length limits to contain OOME risks Contributed by Oleg Kalnichevski Release 4.0 Alpha 1 ------------------- This release represents a complete redesign of the Jakarta Commons HttpClient 3.x API and a significant rewrite of the core HTTP components derived from HttpClient 3.0 code base. These components will form the foundation of the future releases of Jakarta HttpClient and can also be used separately to build custom client- and server-side HTTP services.
