Release 4.3-ALPHA2
-------------------
This is the second 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.
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.
* [HTTPCORE-323] Undocumented UnsupportedCharsetException in org.apache.http.entity.ContentType.getOrDefault.

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

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 Paul Donohue <apache-jira at PaulSD.com> and
Oleg Kalnichevski <olegk at apache.org>
* [HTTPCORE-316] HeaderGroup#clone removes headers from the original object.
Contributed by Markus Thies <markus at dr-thies.com>
* [HTTPCORE-315] AbstractNIOConnPool fails to correctly deallocate connection if it is immediately
released from the session request callback causing a resource leak.
Contributed by Scott Stanton <snstanton at gmail.com>
* [HTTPCORE-313] ContentType#parse now ignores empty and blank charset attributes.
HttpEntityUtils#toString now throws checked I/O exception if it encounters an unsupported
charset.
Contributed by Oleg Kalnichevski <olegk at apache.org>
Release 4.2.2
-------------------
This is a maintenance release that fixes a number of bugs and regressions found since 4.2.1
including a major bug in the NIO module causing incorrect handling of outgoing Content-Length
delimited messages larger than 2GB.
Users of HttpCore 4.2 are advised to upgrade.
Changelog
-------------------
* [HTTPCORE-312] NIO length delimited content encoder incorrectly handles messages larger than 2GB.
Contributed by Oleg Kalnichevski <olegk at apache.org>
* [HTTPCORE-310] Fixed regression in DefaultConnectionReuseStrategy causing it to incorrectly
flag connections as non-reusable after a 204, 205 or 304 response.
Contributed by Oleg Kalnichevski <olegk at apache.org>
* [HTTPCORE-309] Fixed regression in HttpAsyncRequestExecutor causing it to handle 204, 205
and 304 responses incorrectly by returning a message with an enclosed content body.
Contributed by Oleg Kalnichevski <olegk at apache.org>
* [HTTPCORE-306] I/O reactor TCP_NODELAY parameter now defaults to true.
Contributed by Oleg Kalnichevski <olegk at apache.org>
* [HTTPASYNC-21] request execution handler does not get closed in case of a premature HTTP
exchange termination.
Contributed by Oleg Kalnichevski <olegk at apache.org>
* [HTTPCORE-303] ContentType made Serializable.
Contributed by Oleg Kalnichevski <olegk at apache.org>
Release 4.2.1
-------------------
This is a maintenance release that fixes a non-critical number of bugs found since 4.2.
Users of HttpCore 4.2 are encouraged to upgrade.
Changelog
-------------------
* [HTTPCORE-299] ContentType should rely on Charset#name() instead of Charset#toString()
for building header value.
Contributed by Oleg Kalnichevski <olegk at apache.org>
* [HTTPCORE-263] Under rare circumstances incorrectly delineated or garbled HTTP message
can cause an IndexOutOfBoundsException in AbstractSessionInputBuffer#readLine()
Contributed by Michael Pujos <bubbleguuum at free.fr>
* Made connection pools use FIFO algorithm instead of LIFO when leasing / releasing persistent
connections.
Contributed by Oleg Kalnichevski <olegk at apache.org>
* [HTTPCORE-298] Fixed non-blocking SSLIOSession state can getting out of sync with the underlying
IOSession in case the I/O session is terminated by the I/O reactor rather than by the protocol
handler.
Contributed by Sandeep Tamhankar <sandman at electric-cloud.com>
* Fixed NPE in StringEntity constructor thrown if ContentType#getCharset is null.
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>
* AbstractHttpClientConnection#isResponseAvailable method now catches SocketTimeoutException
and returns false.
Contributed by Oleg Kalnichevski <olegk at apache.org>
* [HTTPCORE-296] Server side connections (both blocking and non-blocking) can now handle entity
enclosing requests without Content-Length and Transfer-Encoding headers.
Contributed by Oleg Kalnichevski <olegk at apache.org>
* [HTTPCORE-295] [HTTPCORE-288] Provided direct access to the underlying socket of non-blocking
HTTP connection to allow modification of socket level settings such as TCP_NODELAY, SO_KEEPALIVE,
TrafficClass, etc.
Contributed by Oleg Kalnichevski <olegk at apache.org>
* [HTTPCORE-289] HttpAsyncService fails to invoke Cancellable#cancel() when the ongoing HTTP
exchange is aborted by the client.
Contributed by Oleg Kalnichevski <olegk at apache.org>
Incompatible changes
--------------------
[Compared to release version 4.1.4]
The following methods have been deprecated for some time now and have been deleted:
org.apache.http.impl.SocketHttpServerConnection#createHttpDataReceiver(Socket, int, HttpParams)
org.apache.http.impl.SocketHttpServerConnection#createHttpDataTransmitter(Socket, int, HttpParams)
org.apache.http.protocol.HttpRequestHandlerRegistry#matchUriRequestPattern(String, String)
The following classes have been deprecated for some while now and have been deleted:
org.apache.http.nio.entity.ByteArrayNIOEntity
org.apache.http.nio.entity.FileNIOEntity
org.apache.http.nio.entity.HttpNIOEntity
org.apache.http.nio.entity.StringNIOEntity
org.apache.http.nio.protocol.NHttpClientHandlerBase
org.apache.http.nio.protocol.NHttpServiceHandlerBase
Release 4.2-BETA1
-------------------
This is the first BETA 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 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.
This release also incorporates bug fixes from the stable 4.1.x branch and includes an updated
HttpCore tutorial.
Release 4.1.4
-------------------
This is a maintenance release that fixes a number of bugs found since 4.1.3. It is also likely
to be the last release in the 4.1.x branch.
Changelog

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.
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.

-------------------
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).

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.
