Apache 2.0alpha4 Released
-------------------------

The Apache Group is pleased to announce the release of the fourth public
alpha release of Apache 2.0.  

Apache 2.0 offers numerous enhancements, improvements and performance
boosts over the 1.3 codebase. The most visible and noteworthy addition
is the ability to run Apache in a hybrid thread/process mode on any
platform that supports both threads and processes.  This has shown to
improve the scalability of the Apache HTTPD server significantly in
our early testing, on some versions of Unix.  This release also
greatly improves the performance and robustness of Apache on the
Microsoft Windows Operating Systems.  Lastly we are proud to announce
support for BeOS in this version of the server.

There are more than 45 bug fixes and enhancements since alpha 3. They
are listed in the bottom of this announcement.

Apache 2.0a4 under UNIX has undergone some testing, but there are some
known issues in the current release (hey, it is an "alpha" for a
reason!). It is intended for developers and experienced Apache HTTPD
administrators to play around with and work on. It is not a production
release. If you do not feel comfortable compiling and working with
code, the Apache Group strongly recommends that you wait for a more
stable beta release before you try this version.

Apache 2.0a4 under Windows has undergone some testing as well.  There
are known issues in the current release with regards to Apache on windows
95 and 98.  We are working through those problems, and hope to have them
fixed for future releases of the 2.0 alpha.

There are new snapshots of the Apache httpd source available every 6
hours from http://dev.apache.org/from-cvs/apache-2.0/ - please
download and test if you feel brave. We don't guarantee anything
except that it will take up disk space, but if you have the time and
skills, please give it a spin on your platforms.

Apache has been the most popular web server on the Internet since
April of 1996. The May 2000 WWW server site survey by Netcraft (see:
http://www.netcraft.co.uk/Survey/) found that more web servers were
using Apache than any other software running on more than 60% of the
Internet web servers.

Changes with Apache 2.0a4 since Apache 2.0a3

  *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
     won't need to call it.  [Greg Ames, Jeff Trawick]

  *) Move pre_config hook call to between configuration read and config
     tree walk.  This allows all modules to implement pre_config hooks
     and know that they will be called at an appropriate time.
     [Ryan Bloom] 

  *) mod_cgi, mod_cgid: Make ScriptLog directive work again.  
     [Jeff Trawick]

  *) Add pre-config hooks back to all modules.
     [Ryan Bloom]

  *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
     ContentDigest enabled and we can't/don't mmap the file. 
     [Jeff Trawick]

  *) We now report the correct line number for syntax errors in config
     files.  [Ryan Bloom, Greg Stein, Jeff Trawick]

  *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
     related bugs, and changed shmem/locking to use apr API. Shared-mem
     is currently disabled, however, because of problems with graceful
     restarts. [Ronald Tschalär]

  *) Fix corruption of IFS variable in --with-module= handling.  
     Depending on the user's shell or customization thereof, there 
     would be errors generating ap_config_auto.h later in the configure
     procedure.  [Jeff Trawick]

  *) mod_cgi: Restore logging of stderr from child process when ScriptLog 
     isn't used (as in 1.3), except that on Unix it is now logged via 
     ap_log_rerror() instead of by the child having STDERR_FILENO refer
     to the error log.  [Greg Ames, Jeff Trawick]

  *) Add '-D' argument processing for run time configuration defines.
     [William Rowe]

  *) Organize http_main.c as independent code, such that no code or
     global data is exported from it.  WIN32 will dynamically link it
     to the server core, so this will prevent mutual dependency.
     [William Rowe]

  *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
     and APR_VAR_EXPORT to correctly resolve apr functions and globals.
     [William Rowe]

  *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
     [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]

  *) Add mod_charset_lite for configuring character set translation.
     [Jeff Trawick]

  *) Add '-n' option to htpasswd to make it print its user:pw record
     on stdout rather than having to frob a text file.  [Ken Coar]

  *) Fix saferead.  Basically, we flush the output buffer if a read on the
     input will block.
     [Ryan Bloom]
 
  *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
     a conversion is single-byte only. [Jeff Trawick]

  *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
     the BeOS 5.0 documentation says that shutdown doesn't work yet.
     [Roy Fielding]

  *) Fix some minor errors where pid was being manipulated as an int
     instead of the portable pid_t.  [Roy Fielding]

  *) Fix some error log prints that were printing the pointer to a
     structure rather than the pid within the structure.
     [Jeff Trawick, Roy Fielding]

  *) ab: Fix a command-line processing bug; track bad headers in 
     err_response; support reading headers up to 2K. 
     [Ask Bjoern Hansen <ask@valueclick.com>]

  *) Fix ap_resolve_env() so that it handles new function added in a prior
     alpha (see "Added the capability to do ${ENVVAR} constructs in the
     config file.") as well as the constructs used by mod_rewrite.
     [Paul Reder <rederpj@raleigh.ibm.com>]

  *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]

  *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
     APR to perform translation, instead of accessing the hard-coded tables
     in 1.3's ebcdic.c. [Jeff Trawick]

  *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing. 
     [Jeff Trawick]

  *) Add the ability to hook into the config file reading phase.  Basically
     if a directive is specified EXEC_ON_READ, then when that directive is
     read from the config file, the assocaited function is executed.  This
     should only be used for those directives that must muck with HOW the
     server INTERPRETS the config.  This should not be used for directives
     that re-order or replace items in the config tree.  Those changes should
     be made in the pre-config step.
     [Ryan Bloom]

  *) Add mod_example to the build system.
     [Tony Finch]

  *) APR: Add ap_xlate_conv_byte() to convert one char between single-
     byte character sets. [Jeff Trawick]

  *) Pick up various EBCDIC fixes from 1.3 (from Martin
     Kraemer and Oliver Reh originally according to the change log).
     [Jeff Trawick]

  *) Fix a couple of problems in RFC1413 support (controlled by the
     IdentityCheck directive).  Apache did not build the request string
     properly and more importantly Apache would loop forever if the 
     would-be ident server dropped the connection before sending a
     properly terminated response. [Jeff Trawick]

  *) apxs works in 2.0.
     [Ryan Bloom]

  *) Reliable piped logs work in 2.0.
     [Ryan Bloom]

  *) Introduce a hash table implementation into APR to be used for
     replacing tables and other random data structures in Apache.
     [Tony Finch]

  *) Add some more error reporting to htpasswd in the case of problems
     generating or accessing the temporary file.  Also, pass in a
     buffer if the implementation knows how to use it (i.e., if L_tmpnam
     is defined).  [Ken Coar]

  *) Configure creates config.nice now containing your configure
     options. Syntax: ./config.nice [--more-options]
     [Sascha Schumann]

  *) Fix various return code problems in APR on Win32.  For most of
     these, APR was returning APR_EEXIST instead of GetLastError()/
     WSAGetLastError().  [Jeff Trawick]

  *) Make piped logs work again in version 2.0
     [Ryan Bloom]

  *) Add VPATH support to UNIX build system of Apache and APR.
     [Sascha Schumann]

  *) Fix ap_tokenize_to_argv to respect the const arguments that are
     passed to it.
     [Ryan Bloom]

  *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
     Patch submitted to author.
     [Sascha Schumann]

  *) Fix mm configuration on Solaris 8 x86 and OS/390.  Don't require
     /sbin in PATH on FreeBSD (all submitted to rse previously) 
     [Jeff Trawick]

  *) Fix building Pthread-based MPMs on OpenBSD
     [Sascha Schumann] PR#26

  *) Fix ap_readdir() problem on systems where d_name[] field in
     struct dirent is declared with only one byte.  (This problem only 
     affected multithreaded builds.)  This caused a segfault during
     pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at 
     least). [Jeff Trawick]

  *) Fix some make-portability problems on at least Tru64, Irix
     and UnixWare.
     [Sascha Schumann] PR#18, PR#39

  *) Add ap_sigwait() to support old-style sigwait() on systems
     like OS/390 and UnixWare.
     [Sascha Schumann] 

  *) Add POSIX-thread flags for more platforms.
     [Sascha Schumann]

  *) Fix some minor bugs in ap_strerror().  Teach ap_strerror()
     (on Unix, at least) to handle resolver errors.  Fix a bug in
     the definition of APR_ENOMEM so that ap_strerror() can spit
     out the correct error message for it.
     [Jeff Trawick]
