Contributed by Ignat Alexeyenko <ignatalexeyenko at gmail.com> * 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 <olegk at apache.org> 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. Changelog ------------------- * [HTTPCORE-345] EntityAsyncContentProducer fails to release resources allocated by the underlying entity when #produceContent is never invoked. Contributed by Tad Whitenight <tadwhitenight at gmail.com> * Non-blocking connection pool to avoid scanning the entire queue of pending connection requests on each connection lease / release operation (under heavy load the request queue can contain a significant number of pending requests, a full linear scan of which can cause massive performance degradation). Contributed by Oleg Kalnichevski <olegk at apache.org> * Use bulk ByteBuffer#put method instead of single byte ByteBuffer#put Contributed by Oleg Kalnichevski <olegk at apache.org> * [HTTPCORE-336] Unhandled CancelledKeyException leads to a shutdown of the underlying IOReactor.

Contributed by Thomas Dudek <mail.dudek at gmail.com> Release 4.3-BETA1 ------------------- This is the first BETA release from the 4.3.x release branch. The main theme 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. This release also includes performance optimizations intended to reduce TCP packet fragmentation when writing out HTTP messages both in blocking and non-blocking I/O modes, which should result in up to 20% higher throughput for short entity enclosing messages. This release also includes all fixes from the stable 4.2.x release branch. Changelog ------------------- * Reduced TCP packet fragmentation when writing out message content with blocking and non-blocking connections. Contributed by Oleg Kalnichevski <olegk at apache.org> * [HTTPCORE-330] Clarify InputStreamEntity length constructor argument.

Contributed by Oleg Kalnichevski <olegk at apache.org> Release 4.1-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. Changelog ------------------- * [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 <olegk at apache.org> Release 4.2 ------------------- This is the first stable (GA) release of HttpCore 4.2. The most notable features included in this release are connection pool components for blocking and non-blocking HTTP connections and new asynchronous client and server side protocol handlers. New protocol handling API used in conjunction with connection pooling components is expected to make development of asynchronous HTTP client agents and HTTP proxies easier and less error prone. Connection pool components are based on mature code migrated from HttpClient and HttpAsyncClient modules but have a slightly different API that makes a better use of Java standard concurrent primitives. Changelog ------------------- * Fixed HttpAsyncRequestExecutor incorrect execution of message exchanges that span across multiple hosts (for instance, in case of a request redirect).

Contributed by Oleg Kalnichevski <olegk at apache.org> 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. Several classes and methods deprecated between versions 4.0-beta1 and 4.0 GA (more than two years ago) have been removed in this release. Changelog ------------------- * [HTTPCORE-270] Fixed IllegalStateException in AbstractSessionOutputBuffer and AbstractSessionInputBuffer. Contributed by William R. Speirs <bill.speirs at gmail.com> * [HTTPCORE-269] Connection pools incorrectly handle lease requests when the max limit for the given route has been exceeded and all connections in the route pool are stateful. Contributed by Oleg Kalnichevski <olegk at apache.org> Release 4.2-ALPHA1 ------------------- This is the first ALPHA release of 4.2. The most notable feature included in this release is support for connection pools of blocking and non-blocking HTTP connections. Connection pool components are based on mature code migrated from HttpClient and HttpAsyncClient modules but have a slightly different API that makes a better use of Java standard concurrent primitives. Support for connection pools in HttpCore is expected to make development of client and proxy HTTP services easier and less error prone.

Perera <asankha at apache.org> and Oleg Kalnichevski <olegk at apache.org> Release 4.0 ------------------- This is the first stable (GA) release of HttpCore 4.0. 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 <olegk at apache.org> * [HTTPCORE-175] Chunk decoders no longer accept truncated chunks as valid input. Contributed by Oleg Kalnichevski <olegk at apache.org> Release 4.0 Beta 3 ------------------- The third BETA version of HttpComponents Core has been released.

Contributed by Oleg Kalnichevski <olegk at apache.org> * [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 <olegk at apache.org> * [HTTPCORE-170] Fixed race condition in SharedOutputBuffer. Contributed by Jason Walton <Jason.Walton at alcatel-lucent.com> * [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.
