Release 4.0 Alpha 4 ------------------- ALPHA4 marks the completion of the overhaul of the connection management code in HttpClient. All known shortcomings of the old HttpClient 3.x connection management API have been addressed. NTLM authentication remains the only missing major feature in the new codeline that prevents us from moving awards the API freeze. There has been a number of important bug fixes since ALPHA3. All upstream projects are encouraged to upgrade to the latest release. ------------------- HttpClient 3.x features that have NOT yet been ported: ------------------- * NTLM authentication scheme ------------------- Changelog: ------------------- * [HTTPCLIENT-769] Do not pool connection marked non-reusable. Contributed by Oleg Kalnichevski * [HTTPCLIENT-763] Fixed problem with AbstractClientConnAdapter#abortConnection() not releasing the connection if called from the main execution thread while there is no blocking I/O operation. Contributed by Oleg Kalnichevski * [HTTPCLIENT-652] Added optional state attribute to managed client connections. This enables connection managers to correctly handle stateful connections. Contributed by Oleg Kalnichevski * [HTTPCLIENT-673] Revised max connections per route configuration Contributed by Oleg Kalnichevski * [HTTPCLIENT-753] Class Scheme and related classes moved to a separate package Contributed by Oleg Kalnichevski * [HTTPCLIENT-757] Improved request wrapping in the DefaultClientRequestDirector. This also fixed the problem with the default proxy set at the client level having no effect. Contributed by Oleg Kalnichevski * [HTTPCLIENT-734] Request abort will unblock the thread waiting for a connection Contributed by Sam Berlin * [HTTPCLIENT-759] Ensure release of connections back to the connection manager on exceptions. Contributed by Sam Berlin * [HTTPCLIENT-758] Fixed the use of generics in AbstractHttpClient #removeRequestInterceptorByClass and #removeResponseInterceptorByClass Contributed by Johannes Koch * [HTTPCLIENT-749] HttpParams beans Contributed by Stojce Dimski * [HTTPCLIENT-755] Workaround for known bugs in java.net.URI.resolve() Bug ID: 4708535 Contributed by Johannes Koch HttpClient API changes (generated by JarDiff 0.2) -------------------------------------- Class removed: public org.apache.http.client.methods.UrlEncodedFormEntity extends org.apache.http.entity.AbstractHttpEntity Class removed: public org.apache.http.client.utils.URLUtils extends java.lang.Object Class removed: public abstract org.apache.http.conn.LayeredSocketFactory extends java.lang.Object implements org.apache.http.conn.SocketFactory Class removed: public final org.apache.http.conn.PlainSocketFactory extends java.lang.Object implements org.apache.http.conn.SocketFactory Class removed: public final org.apache.http.conn.Scheme extends java.lang.Object Class removed: public final org.apache.http.conn.SchemeRegistry extends java.lang.Object Class removed: public abstract org.apache.http.conn.SocketFactory extends java.lang.Object Class removed: public org.apache.http.conn.util.SocketUtils extends java.lang.Object Class removed: public org.apache.http.impl.client.RoutedRequest.Impl extends java.lang.Object implements org.apache.http.impl.client.RoutedRequest Class added: public org.apache.http.auth.params.AuthParamBean extends org.apache.http.params.HttpAbstractParamBean Class added: public org.apache.http.client.entity.UrlEncodedFormEntity extends org.apache.http.entity.StringEntity Class added: public org.apache.http.client.params.ClientParamBean extends org.apache.http.params.HttpAbstractParamBean Class added: public org.apache.http.client.protocol.ClientContextConfigurer extends java.lang.Object Class added: public org.apache.http.client.utils.URIUtils extends java.lang.Object Class added: public org.apache.http.client.utils.URLEncodedUtils extends java.lang.Object Class added: public abstract org.apache.http.conn.ClientConnectionRequest extends java.lang.Object Class added: public final org.apache.http.conn.MultihomePlainSocketFactory extends java.lang.Object implements org.apache.http.conn.scheme.SocketFactory Class added: public org.apache.http.conn.params.ConnConnectionParamBean extends org.apache.http.params.HttpAbstractParamBean Class added: public org.apache.http.conn.params.ConnManagerParamBean extends org.apache.http.params.HttpAbstractParamBean Class added: public abstract org.apache.http.conn.params.ConnPerRoute extends java.lang.Object Class added: public final org.apache.http.conn.params.ConnPerRouteBean extends java.lang.Object implements org.apache.http.conn.params.ConnPerRoute Class added: public org.apache.http.conn.params.ConnRouteParamBean extends org.apache.http.params.HttpAbstractParamBean Class added: public abstract org.apache.http.conn.scheme.LayeredSocketFactory extends java.lang.Object implements org.apache.http.conn.scheme.SocketFactory Class added: public final org.apache.http.conn.scheme.PlainSocketFactory extends java.lang.Object implements org.apache.http.conn.scheme.SocketFactory Class added: public final org.apache.http.conn.scheme.Scheme extends java.lang.Object Class added: public final org.apache.http.conn.scheme.SchemeRegistry extends java.lang.Object Class added: public abstract org.apache.http.conn.scheme.SocketFactory extends java.lang.Object Class added: public org.apache.http.cookie.params.CookieSpecParamBean extends org.apache.http.params.HttpAbstractParamBean Class added: public org.apache.http.impl.conn.tsccm.Aborter extends java.lang.Object Class added: public abstract org.apache.http.impl.conn.tsccm.PoolEntryRequest extends java.lang.Object Class added: public org.apache.http.impl.conn.tsccm.WaitingThreadAborter extends java.lang.Object Class changed: org.apache.http.auth.AuthSchemeRegistry Methods added: public synchronized void setItems(java.util.Map);

As of this release HttpClient requires Java 5 compatible runtime environment and takes full advantage of generics and new concurrency primitives. This release also introduces new default cookie policy that selects a cookie specification depending on the format of cookies sent by the target host. It is no longer necessary to know beforehand what kind of HTTP cookie support the target host provides. HttpClient is now able to pick up either a lenient or a strict cookie policy depending on the compliance level of the target host. Another notable improvement is a completely reworked support for multipart entities based on Apache mime4j library. ------------------- HttpClient 3.x features that have NOT yet been ported: ------------------- * NTLM authentication scheme ------------------- Changelog: ------------------- * [HTTPCLIENT-742] common interface for HttpRoute and RouteTracker Contributed by Roland Weber * [HTTPCLIENT-741] Fixed concurrency issues in AbstractClientConnAdapter.

This release finally addresses several design flaws that existed since the 1.0 release and could not be fixed without a major code overhaul and breaking API compatibility. The HttpClient 4.0 API is still very experimental and is bound to change during the course of the ALPHA development phase. Several important features have not yet been ported to the new API. Architectural changes --------------------- * Redesign of the HttpClient internals addressing all known major architectural shortcomings of the 3.x codeline * Cleaner, more flexible and expressive API * Better performance and smaller memory footprint due to a more efficient HTTP transport based on HttpCore. HttpClient 4.0 is expected to be 10% to 25% faster than HttpClient 3.x codeline * More modular structure * Pluggable redirect and authentication handlers * Support for protocol incerceptors * Improved connection management * Improved support for sending requests via a proxy or a chain of proxies * Improved handling redirects of entity enclosing requests * More flexible SSL context customization * Reduced intermediate garbage in the process of generating HTTP requests and parsing HTTP responses ------------------- HttpClient 3.x features that have NOT yet been ported ------------------- * NTLM authentication scheme * RFC2965 cookie policy (Cookie2) * Support for multipart MIME coded entities ------------------- Changelog ------------------- The following is a list of contributions tracked in JIRA. Note that this is not a complete list of contributions or changes. Since the API was redesigned completely, tracking everything outside of the source code repository would have been too burdensome. * [HTTPCLIENT-655] User-Agent string no longer violates RFC Contributed by Oleg Kalnichevski * [HTTPCLIENT-541] Virtual host API redesign Contributed by Oleg Kalnichevski * [HTTPCLIENT-614] Allow for different strategies when checking CN of x509 certificates Contributed by Julius Davies * [HTTPCLIENT-136] Fixed inadequate proxy support Long standing architectural problem.
