Apache MINA is a network application framework which helps users develop high performance and high scalability network applications easily. It provides an abstract, event-driven, asynchronous API over various transports such as TCP/IP and UDP/IP via Java NIO.

The latest release is now available here:

http://mina.apache.org/downloads.html

This release has too many changes and fixed to enumerate in their entirety. Some of the key improvements include:

• Simplified and more consistent API
• Ability to share I/O processor threads between multiple servers and/or
  clients
• Improved support for streaming files
• Improved String and JMX integration
• Improved logging support
• Framework for simplifying state machine creation and maintenance
• Support for synchronous clients
• OSGi integration

This is a milestone release and is not yet considered suitable forproduction use. The intent of this release is to showcase the new modified API and other improvements in MINA. We hope that developers will start to use this release and provide feedback.

Binary and source distributions are available here.

There have been many improvements made since the 1.2 release. A key focus in this version has been ease of use. We’ve simplified developing your own tools by eliminating the ViewTool and Configurable interfaces, and we’ve simplified the syntax for using many of our existing tools within Velocity templates to both save keystrokes and reduce visual clutter.

The distribution also comes with a new showcase example webapp that demonstrates many of the uses of the various tools as well as allowing you to interactively play with them. Just download the binary distribution, and deploy the “showcase.war” example to your servlet container to try it out.

Also included are the usual slate of bug fixes, dependency upgrades, entirely new tools, and new functions for existing tools. For a full listing of changes, see the change log.

Changes with Apache 2.2.4

*) mod_isapi: Correctly present SERVER_PORT_SECURE.
PR: 40573.  [Matt Eaton ]

*) Allow htcacheclean, httxt2dbm, and fcgistarter to link apr/apr-util
statically like the older support programs.
[Eric Covener ]

*) core: Fix NONBLOCK status of listening sockets on restart/graceful
PR 37680.  [Darius Davis ]

*) mod_deflate: Rework inflate output and deflate output filter to fix several
issues: Incorrect handling of flush buckets, potential memory leaks,
excessive memory usage in inflate output filter for large compressed
content. PR 39854. [Ruediger Pluem, Nick Kew, Justin Erenkrantz]

*) mod_mem_cache: Memory leak fix: Unconditionally free the buffer.
[Davi Arnaut ]

*) Allow mod_dumpio to log at other than DEBUG levels via
the new DumpIOLogLevel directive. [Jim Jagielski]

*) rotatelogs: Improve error message for open failures.  PR 39487.
[Joe Orton]

*) mod_dbd: share per-request database handles across subrequests
and internal redirects [Chris Darroch]

*) mod_dbd: key connection pools to virtual hosts correctly even when
ServerName is unset/unavailable [Graham Leggett]

*) Better detection and clean up of ldap connection that has been
terminated by the ldap server.  PR 40878.
[Rob Baily ]

*) mod_mem_cache: Convert mod_mem_cache to use APR memory pool functions
by creating a root pool for object persistence across requests. This
also eliminates the need for custom serialization code.
[Davi Arnaut ]

*) mod_authnz_ldap: Add an AuthLDAPRemoteUserAttribute directive. If
set, REMOTE_USER will be set to this attribute, rather than the
username supplied by the user. Useful for example when you want users
to log in using an email address, but need to supply a userid instead
to the backend.  [Graham Leggett]

*) mod_cgi and mod_cgid: Don’t use apr_status_t error return
from input filters as HTTP return value from the handler.
PR 31579.  [Nick Kew]

*) mod_cache: Eliminate a bogus error in the log when a filter returns
AP_FILTER_ERROR.  [Niklas Edmundsson ]

*) core: Fix issue which could cause piped loggers to be orphaned and never
terminate after a graceful restart.  PR 40651.  [Joe Orton, Ruediger Pluem]

*) core: Fix address-in-use startup failure caused by corruption of the list
of listen sockets in some configurations with multiple generic Listen
directives.  [Jeff Trawick]

*) mod_headers: Support regexp-based editing of HTTP headers.  [Nick Kew]

*) mod_proxy: Add explicit flushing feature. When Servlet container sends AJP
body message with size 0, this means that Servlet container has asked for
an explicit flush. Create flush bucket in that case. This feature has been
added to the recent Tomcat versions without breaking the AJP protocol.
[Mladen Turk]

*) mod_proxy_balancer: Set the new environment variable BALANCER_ROUTE_CHANGED
if a worker with a route different from the one supplied by the client
had been chosen or if the client supplied no routing information for
a balancer with sticky sessions.  [Ruediger Pluem]

*) mod_proxy_balancer: Add information about the route, the sticky session
and the worker used during a request as environment variables. PR 39806.
[Brian ]

*) mod_proxy: Don’t try to use dead backend connection. PR 37770.
[Olivier BOEL ]

*) mod_proxy_balancer: Extract stickysession routing information contained as
parameter in the URL correctly. PR 40400.
[Ruediger Pluem, Tomokazu Harada ]

*) mod_proxy_ajp: Added cping/cpong support for the AJP protocol.
A new worker directive ping=timeout will cause CPING packet
to be send expecting CPONG packet within defined timeout.
In case the backend is too busy this will fail instead
sending the full header.  [Mladen Turk]

*) mod_disk_cache: Make sure that only positive integers are accepted
for the CacheMaxFileSize and CacheMinFileSize parameters in the
config file. PR39380.  [Niklas Edmundsson ]

*) mod_cache: From RFC3986 (section 6.2.3.) if a URI contains an
authority component and an empty path, the empty path is to be equivalent
to “/”. It explicitly cites the following four URIs as equivalents:

http://example.com

http://example.com/

http://example.com:/

http://example.com:80/

[Davi Arnaut ]

*) mod_cache: Don’t cache requests with a expires date in the past;
otherwise mod_cache will always try to cache the URL. This bug
might lead to numerous rename() errors on win32 if the URL was
previously cached. [Davi Arnaut ]

*) core: Deal with the widespread use of apr_status_t return values
as HTTP status codes, as documented in PR#31759 (a bug shared by
the default handler, mod_cgi, mod_cgid, mod_proxy, and probably
others). PR31759.  [Jeff Trawick, Ruediger Pluem, Joe Orton]

*) mod_ext_filter: Handle filter names which include capital letters.
PR 40323.  [Jeff Trawick]

*) mod_isapi: Avoid double trailing slashes in HSE_REQ_MAP_URL_TO_PATH
support.  Also corrects the slashes for Windows.
PR 15993.  [William Rowe]

*) mod_isapi: Handle “HTTP/1.1 200 OK” style status lines correctly, the
token parser worked while the resulting length was misinterpreted.
PR 29098.  [Brock Bland ]

*) mod_isapi: Return 0 (failure) for more of the various ap_pass_brigade
attempts to stream the response at the client.  Log these as well.
PR 30022, 40470.  [William Rowe, Matt Eaton ]

*) mod_isapi: Ensure we walk through all the methods the developer may have
employed to report their HTTP status result code.
PR 16637 30033 28089.  [Matt Lewandowsky , William Rowe]

*) mod_echo: Fix precedence problem in if statement. PR 40658.
[Larry Cipriani ]

*) mod_mime_magic: Fix precedence problem in if statement. PR 40656.
[Larry Cipriani ]

*) The full server version information is now included in the error log at
startup as well as server status reports, irrespective of the setting
of the ServerTokens directive.  ap_get_server_version() is now deprecated,
and is replaced by ap_get_server_banner() and ap_get_server_description().
[Jeff Trawick]

*) mod_proxy_balancer: Workers can now be defined as part of
a balancer cluster “set” in which members of a lower-numbered set
are preferred over higher numbered ones.  [Jim Jagielski]

*) mod_proxy_balancer: Workers can now be defined as “hot standby” which
will only be used if all other workers are unusable (eg: in
error or disabled). Also, the balancer-manager displays the election
count and I/O counts of all workers.  [Jim Jagielski]

*) mod_proxy_ajp: Close connection to backend if reading of request body
fails. PR 40310.  [Ian Abel ]

*) mod_proxy_balancer: Retry worker chosen by route / redirect worker if
it is in error state before sending “Service Temporarily Unavailable”.
PR 38962.  [Christian Boitel ]
