[ANNOUNCEMENT] HttpComponents Client 5.4-alpha2 Released

[Oleg Kalnichevski]

The Apache HttpComponents project is pleased to announce 5.4-alpha2
release of HttpComponents HttpClient.

This is the second and likely the last ALPHA release in the 5.3 release
series. It finalizes the new Cache API introduced in the previous ALPHA
release and also improves TLS customization for the classic transport,
SNI and endpoint identification support, authentication data caching,
and HTTP context performance. It also introduces support for optional
TLS upgrades for HTTP/1.1 connections.


IMPORTANT! Please note the new cache entry serialization format is
incompatible with earlier versions of HttpClient Cache. Persistent
caches (file system based, Memcached, EhCAche with object
serialization) created with any earlier version MUST be flushed and re-
populated or the cache backend MUST be configured to use the old
deprecated cache entry serializer.


Notable changes and features included in the 5.4 series:

* Improved conformance to RFC 9110 (HTTP Semantics), RFC 7616 (HTTP
Digest Access Authentication), RFC 2617 (’Basic’ HTTP Authentication
Scheme).

* UTF-8 encoding to be used by default for text where appropriate.

* Compatibility with Java Virtual Threads and Java 21 Runtime.

* Redesign and rewrite of the HTTP caching protocol layer for better
efficiency and improved conformance to RFC 9111 (HTTP Caching).

* Cache control and context APIs.

* ETag APIs.

* TLS SNI and endpoint identification improvements.

* Support for RFC 2817 (Upgrading to TLS Within HTTP/1.1).

* Auth cache no longer makes use of Java serialization.

* Deprecation of ConnectionSocketFactory and
LayeredConnectionSocketFactory.

* HttpContext optimization and performance improvement.

increasing the number of applications that require HTTP support.

Designed for extension while providing robust support for the base HTTP
protocol, HttpClient may be of interest to anyone building HTTP-aware
client applications such as web browsers, web service clients, or
systems that leverage or extend the HTTP protocol for distributed
communication.

The Hyper-Text Transfer Protocol (HTTP) is perhaps the most
significantprotocol used on the Internet today. Web services, network-
enabled appliances and the growth of network computing continue to
expand the role of the HTTP protocol beyond user-driven web browsers,
while increasing the number of applications that require HTTP support.

Although the java.net package provides basic functionality for
accessing resources via HTTP, it doesn't provide the full flexibility
or functionality needed by many applications. HttpClient seeks to fill
this voidby providing an efficient, up-to-date, and feature-rich
package implementing the client side of the most recent HTTP standards
and recommendations.

Designed for extension while providing robust support for the base HTTP
protocol, HttpClient may be of interest to anyone building HTTP-aware
client applications such as web browsers, web service clients, or
systems that leverage or extend the HTTP protocol for distributed
communication.

[CVE-2020-13956] Apache HttpClient incorrect handling of malformed URI authority component

[Oleg Kalnichevski]

CVE-2020-13956: Apache HttpClient incorrect handling of malformed
authority component in request URIs

Severity: Medium

Vendor:
The Apache Software Foundation

Versions Affected:
Apache HttpClient 4.5.12 and prior 
Apache HttpClient 5.0.2 and prior

Description:

Apache HttpClient versions prior to version 4.5.13 and 5.0.3 can
misinterpret malformed authority component in request URIs passed to
the library as java.net.URI object and pick the wrong target host for
request execution.  

Mitigation:

As of release 4.5.13 and 5.0.3 HttpClient will reject URIs with
ambiguous malformed authority component as invalid. Users of HttpClient
are advised to upgrade to version 4.5.13 or 5.0.3 and sanitize request
URIs when using java.net.URI as input.

Credit:
This issue was discovered and reported by Priyank Nigam

About HttpComponents HttpClient

The Hyper-Text Transfer Protocol (HTTP) is perhaps the most significant
protocol used on the Internet today. Web services, network-enabled
appliances and the growth of network computing continue to expand the
role of the HTTP protocol beyond user-driven web browsers, while
increasing the number of applications that require HTTP support.

Although the java.net package provides basic functionality for
accessing resources via HTTP, it doesn't provide the full flexibility
or functionality needed by many applications. HttpClient seeks to fill
this void by providing an efficient, up-to-date, and feature-rich
package implementing the client side of the most recent HTTP standards
and recommendations.

Designed for extension while providing robust support for the base HTTP
protocol, HttpClient may be of interest to anyone building HTTP-aware
client applications such as web browsers, web service clients, or
systems that leverage or extend the HTTP protocol for distributed
communication.

About HttpComponents Core

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: a blocking I/O
model based on the classic Java I/O and a non-blocking, event driven
I/O model based on Java NIO.

[ANNOUNCEMENT] HttpComponents Core 5.0 beta11 (GA candidate) released

[Oleg Kalnichevski]

The Apache HttpComponents project is pleased to announce 5.0-beta11 (GA
candidate) release of HttpComponents Core. 

This BETA improves handling of illegal or invalid requests on the
server side and fixes a number of defects in HTTP/2 protocol code found
since the last release.

IMPORTANT: This release is expected to be the last BETA version. If no
major design flaws are found the actual 5.0 API will be frozen and the
next version will be promoted to GA.


Notable changes and features included in the 5.0 series:

* Support for HTTP/2 protocol and conformance to requirements and
recommendations of the latest HTTP/2 protocol specification (RFC 7540,
RFC 7541)

  Supported features:

** HPACK header compression
** stream multiplexing (client and server)
** flow control
** response push (client and server)
** message trailers
** expect-continue handshake
** connection validation (ping)
** application-layer protocol negotiation (ALPN) on Java 9+
** TLS 1.2 security features

   Features out of scope for 5.0 release:

** padding of outgoing frames
** stream priority
** plain connection HTTP/1.1 upgrade
** CONNECT method

* Improved conformance to requirements and recommendations of the
latest HTTP/1.1 protocol specification (RFC 7230, RFC 7231)

* New asynchronous HTTP transport APIs consistent for both HTTP/1.1 and
HTTP/2 transport.

* Redesigned I/O reactor APIs and improved NIO based reactor
implementation for a greater performance and scalability.

* Support for server side request filters for classic and asynchronous
server implementations. Request filters could be used to implement
cross-cutting protocol aspects such as the 'expect-continue'
handshaking and user authentication / authorization.

* Redesigned connection pool implementation with strict connection
limit guarantees. The connection pool is expected to have a better
performance under higher concurrency due to reduced global pool lock
contention.

* New connection pool implementation with lax connection limit
guarantees and better performance under higher concurrency due to
absence of a global pool lock.

* Package name space changed to 'org.apache.hc.core5'

* Maven group id changed to 'org.apache.httpcomponents.core5'

HttpCore 5.0 releases can be co-located with earlier versions.

The 5.0 APIs are considered feature complete and are not expected to
undergo any major changes anymore. The focus of development is now
shifting to API polish, code stabilization and documentation
improvements.

About HttpComponents HttpClient

The Hyper-Text Transfer Protocol (HTTP) is perhaps the most significant
protocol used on the Internet today. Web services, network-enabled
appliances and the growth of network computing continue to expand the
role of the HTTP protocol beyond user-driven web browsers, while
increasing the number of applications that require HTTP support.

Although the java.net package provides basic functionality for
accessing resources via HTTP, it doesn't provide the full flexibility
or functionality needed by many applications. HttpClient seeks to fill
this void by providing an efficient, up-to-date, and feature-rich
package implementing the client side of the most recent HTTP standards
and recommendations.

Designed for extension while providing robust support for the base HTTP
protocol, HttpClient may be of interest to anyone building HTTP-aware
client applications such as web browsers, web service clients, or
systems that leverage or extend the HTTP protocol for distributed
communication.

[ANNOUNCEMENT] HttpComponents Core 5.0 beta6 released

[Oleg Kalnichevski]

The Apache HttpComponents project is pleased to announce 5.0-beta6

library, and fixes a number of defects found since the previous
release.

Notable changes and features included in the 5.0 series:

* Support for HTTP/2 protocol and conformance to requirements and
recommendations of the latest HTTP/2 protocol specification (RFC 7540,
RFC 7541)

[ANNOUNCEMENT] HttpComponents Client 5.0 alpha2 released

[Oleg Kalnichevski]

The Apache HttpComponents project is pleased to announce 5.0-alpha2
release of HttpComponents Client. 

This is a major release that introduces support for HTTP/2 protocol and
event driven messaging APIs consistent for all supported HTTP protocol
versions.

HttpClient ships with two client implementations:

* Classic: it is based on the classic (blocking) I/O model; largely
compatible with the 4.x APIs; supports HTTP/1.1 only.

* Async: based on NIO model; new event driven APIs consistent for all
supported HTTP protocol versions; supports both HTTP/1.1 and HTTP/2.

Notable changes and features included in the 5.0 series are:

* Partial support for HTTP/2 protocol and conformance to requirements
and recommendations of the latest HTTP/2 protocol specification (RFC
7540, RFC 7541)

  Supported features:

** HPACK header compression
** stream multiplexing (client and server)
** flow control
** response push
** message trailers
** expect-continue handshake
** connection validation (ping)
** application-layer protocol negotiation (ALPN) on Java 1.9+
** TLS 1.2 security features

* Improved conformance to requirements and recommendations of the
latest HTTP/1.1 protocol specification (RFC 7230, RFC 7231)

* Redesigned connection pool implementation with reduced pool lock
contention.

* Package name space changed to 'org.apache.hc.client5'

* Maven group id changed to 'org.apache.httpcomponents.client5'

* Apache Log4j2 logging APIs used for internal logging instead of
Commons Logging APIs

!!!IMPORTANT!!! 
If you disagree with our choice of the logging APIs please do let us
know by posting a message to d...@hc.apache.org  

Fetures presently that are presently NOT supported:

* HTTP/2 transport (classic)

* HTTP tunneling (async)

* Automatic response content decompression (async)

* Caching (async)


HttpClient 5.0 releases can be co-located with earlier versions.

Please note that as of 5.0 HttpClient requires Java 1.7 or newer.

!!!IMPORTANT!!! 
We have been considering upgrading minimal JRE level to 1.8 for all
HttpClient 5.x artifacts. If you would like HttpClient to remain 1.7
compatible please do let us know by posting a message to dev@hc.apache.
org  

Please note that at this point 5.0 APIs are considered API experimental

About HttpComponents HttpClient

The Hyper-Text Transfer Protocol (HTTP) is perhaps the most significant
protocol used on the Internet today. Web services, network-enabled
appliances and the growth of network computing continue to expand the
role of the HTTP protocol beyond user-driven web browsers, while
increasing the number of applications that require HTTP support.

Although the java.net package provides basic functionality for accessing
resources via HTTP, it doesn't provide the full flexibility or
functionality needed by many applications. HttpClient seeks to fill this
void by providing an efficient, up-to-date, and feature-rich package
implementing the client side of the most recent HTTP standards and
recommendations.

Designed for extension while providing robust support for the base HTTP
protocol, HttpClient may be of interest to anyone building HTTP-aware
client applications such as web browsers, web service clients, or
systems that leverage or extend the HTTP protocol for distributed
communication.

This is the first stable (GA) release of HttpAsyncClient 4.1. Notable
features and enhancements included in 4.1 series are:

* Support for pipelined request execution 

* Support for the latest HTTP state management specification (RFC 6265).
Please note that the old cookie policy is still used by default for
compatibility reasons. RFC 6265 compliant cookie policies need to be
explicitly configured by the user. Please also note that as of next
feature release support for Netscape draft, RFC 2109 and RFC 2965 cookie
policies will be deprecated and disabled by default. It is recommended
to use RFC 6265 compliant policies for new applications unless
compatibility with RFC 2109 and RFC 2965 is required and to migrate
existing applications to the default cookie policy.

* Enhanced, redesigned and rewritten default SSL hostname verifier with
improved RFC 2818 compliance

* Default SSL hostname verifier and default cookie policy now validate
certificate identity and cookie domain of origin against the public
suffix list maintained by Mozilla.org
https://publicsuffix.org/list

* Authentication cache thread-safety: authentication cache used by
HttpClient is now thread-safe and can be shared by multiple threads in
order to re-use authentication state for subsequent requests

The Apache HttpComponents project is pleased to announce 4.4 GA
release of HttpComponents HttpClient.

Notable features and enhancements included in 4.4 series are:

* Support for the latest HTTP state management specification (RFC 6265).
Please note that the old  cookie policy is still used by default for
compatibility reasons. RFC 6265 compliant cookie policies need to be

improved RFC 2818 compliance

* Default SSL hostname verifier and default cookie policy now validate
certificate identity and cookie domain of origin against the public
suffix list maintained by Mozilla.org https://publicsuffix.org/list

* More efficient stale connection checking: indiscriminate connection
checking which results in approximately 20 to 50 ms overhead per request
has been deprecated in favor of conditional connection state validation
(persistent connections are to be re-validated only if a specified
period inactivity has elapsed)

* Authentication cache thread-safety: authentication cache used by
HttpClient is now thread-safe and can be shared by multiple threads in
order to re-use authentication state for subsequent requests

* Native Windows Negotiate and NTLM via SSPI through JNA: when running
on Windows OS HttpClient configured to use native NTLM or SPNEGO
authentication schemes can make use of platform specific functionality
via JNA and current user credentials. This functionality is still
considered experimental, known to have compatibility issues and subject
to change without prior notice. Use at your discretion.

This release also includes all fixes from the stable 4.3.x release
branch.

Please note that as of 4.4 HttpClient requires Java 1.6 or newer.
