                            Apache 2.0.36 Released
                                       
     Apache 2.0.36 was released on 8th May 2002 and is now the latest
     version of the Apache server. This is the second stable release of
     Apache 2.0, following up on 2.0.35 which was released on 6th April
     2002. Read our [1]special feature for more information about the
     history of Apache 2.0.
     
     Apache 2.0.36 is available in source form for compiling on Unix or
     Windows, for download from the [2]main Apache site or from any
     [3]mirror download site.
     
     This is mainly a bug fix release, with a few new features. Users
     should upgrade if they will be affected by the particular bugs
     mentioned below, or would like to use any of the new features.
     
New features

     The new features in this release (added since 2.0.35) are:
     * Two new experimental thread-based MPMs "leader/follower" and
       "threadpool" are included, which aim to address performance
       limitations in the worker MPM
     * Hooks have been added to mod_dav allowing a repository provider
       module to implement the [4]DASL (WebDAV search) specification
     * The new MIME types image/vnd.djvu and application/xhtml+xml are
       included in the default configuration. ([5]BZ#7795, [6]BZ#7969)
       
Bug Fixes

     The bugs fixed in this release include:
     * Many performance and reliability fixes in the worker MPM
     * Several improvements to mod_ssl, including a fix to allow using
       mod_proxy as a reverse SSL to HTTP proxy ([7]BZ#8174), a fix for
       an infinite loop which could be by using Netscape Navigator
       ([8]BZ#8389), a fix for using virtual hosts with long hostnames
       ([9]BZ#8572), and synchronisation with the changes in mod_ssl
       2.8.8
     * The AcceptPathInfo directive has been fixed; previously the logic
       of the directive was inverted ([10]BZ#8234)
     * A fix for sub-request handling which resulted in invalid
       Content-Length headers being returned when using certain
       combinations of modules ([11]BZ#7966)
     * A fix for segfaults seen when generating "invalid byte-range"
       responses (status code 416)
     * mod_proxy fixes: improved error handling ([12]BZ#8407), fixes for
       use of persistent connections ([13]PR#10010) and operation on
       EBCDIC platforms
     * Fixes to HTTP compliance problems: the server will now read
       trailing headers of chunked input bodies, and does allow an empty
       Host: header ([14]BZ#7441)
     * Many small build and configure fixes ([15]BZ#7840, [16]BZ#7818,
       [17]BZ#7802, [18]BZ#7841)
     * Many documentation updates ([19]BZ#8037, [20]BZ#7832, [21]BZ#8144,
       [22]BZ#8643)
       
Platform-specific fixes

     * A fix for a performance problem under high load in the Windows NT
       MPM.
     * A fix for a possible deadlock in the Netware MPM
     * A plethora of portability fixes: including for AIX ([23]BZ#7957,
       [24]BZ#8707), Solaris ([25]BZ#7876, [26]BZ#8214), Mac OS X
       ([27]BZ#7970), and Windows ([28]BZ#7910, [29]BZ#8014, [30]BZ#8009)
       
                               Under development
                                       
     The mod_deflate module included in Apache 2.0 was moved out of the
     "experimental" modules directory this week, indicating it is ready
     for production use. It was noted that some manual configuration is
     needed by those wishing to use this module, to set up BrowserMatch
     directives disabling deflate support for certain browsers which
     have buggy Content-Encoding support (for instance 4.x versions of
     MSIE).
     
     A patch was submitted to the list this week which would make each
     MPM module include an identifying string in the Server response
     header, along with the version of Apache and any major modules.
     Several group members were unhappy with revealing this
     configuration detail; a proposal was even made to restrict the
     information revealed in the Server header to just the Apache
     version using the ServerTokens minimal directive.
     
                    ApacheCon 2002: Call For Participation
                                       
     Now that the date for [31]ApacheCon US 2002, Las Vegas, Nevada, has
     been settled on 18-21 November 2002, the ASF members are starting
     to design its technical program which will include over 40
     sessions. The good news is - you are still in time to sign up to
     present a session which can range from 30 minutes to 2 hours.
     Session proposals can cover any educational issues related to
     projects of the Apache Software Foundation or the Web in general
     excluding commercial sales or marketing presentation. Topics sought
     include:
     * Apache Web server topics (installation, compilation,
       configuration, migration, Version 2.0)
     * All Apache Software Foundation projects (Jakarta, mod_perl,
       Xerces, etc.)
     * scripting languages and dynamic content (Java, PHP, Perl, TCL,
       Python, XML, XSL, etc.)
     * Security and eCommerce
     * Performance tuning, load balancing, high availability
     * tips for writing Apache Web server modules
     * Technical and non-technical case studies
     * new Web-related technologies
       
     If you would like to be a speaker at the ApacheCon 2002 event,
     please go to the ApacheCon site, [32]log in, and choose the "Submit
     a CFP" option from the list provided before Friday 31 May 2002
     17:30 EDT. Should you be interested in giving a vendor
     presentation, please send an email to [33][email protected]
     instead.
     
                               Featured articles
                                       
     In this section we highlight some of the articles on the web that
     are of interest to Apache users.
     
     The Solaris Developer Connection site provides this [34]tutorial
     which guides you through each step of installing Apache 1.3.24,
     mod_ssl 2.8.8, and OpenSSL 0.9.6c on a Solaris platform. It
     explains how to compile and configure Apache with Dynamic Shared
     Object (DSO) support, and load mod_ssl as a DSO module. It also
     provides instructions for generating a sample custom server
     certificate.
     
     Apache developer William Rowe, Jr answers the question of,
     [35]"What's New and Improved in Apache 2.0 on Windows?" by
     examining three major areas in Apache 2.0 that affect the Windows
     platform. The first is the Multi-Processing Module that is
     optimised for Windows NT (mpm_winnt), followed by the Apache
     Portable Runtime (APR) library, and lastly he looks at the most
     important Windows-NT-specific change which is the addition of
     Unicode support.
     
     In [36]"PHP and PostgreSQL", Vikram Vaswani walks us through six
     examples which demonstrate how to use PHP's built-in PostgreSQL
     functions to manipulate data in the database. He shows us how to
     use a few different methods to extract data, apply PostgreSQL
     support for transactions, and debug some PHP scripts using the
     error-handling functions.
