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.

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.

Contributed by Sam Berlin * Fixed concurrency bug in the ThrottlingHttpServerHandler protocol handler. Contributed by Oleg Kalnichevski * Fixed bug in SharedInputBuffer that caused input events to be incorrectly suspended. Contributed by Asankha C. 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 Sam Berlin * [HTTPCORE-143] Ensure the underlying channel is closed if the session request is canceled or times out.

HttpCore is now feature complete and we are planning to freeze the public APIs as of next release (BETA1). * [HTTPCORE-120] new interface HeaderIterator, available from HttpMessage Contributed by Roland Weber * [HTTPCORE-118] Purge closed sessions prior to opening new ones. This should reduce chances of running out of memory when opening and closing lots of NIO connections in a tight loop. Contributed by Oleg Kalnichevski * [HTTPCORE-117] Fixed bug preventing protocol handlers from closing timed out NIO connection when pending output (output session buffer is not empty). Contributed by Oleg Kalnichevski * [HTTPCORE-86] Allow for optional handling of runtime exceptions thrown by protocol handlers to ensure the I/O dispatch thread remains running. Contributed by Oleg Kalnichevski * [HTTPCORE-116] moved parameter names to interfaces Contributed by Roland Weber * [HTTPCORE-109] Improved shutdown process of the I/O reactors in 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.

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.

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.

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 Changelog: --------- * [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.
