Changes for APR 1.0.2

  *) Switch to lazy initialization of the pollset that's used within
     apr_file_t on platforms where apr_wait_for_io_or_timeout() doesn't
     use poll(2).  (This fixes a performance problem observed in httpd-2.x
     on OS X due to the use of poll now being disabled by default on that
     platform.)  [Brian Pane]

  *) Support APR_SO_SNDBUF and APR_SO_RCVBUF on Windows.  PR 32177.
     [Sim <sgobbi datamanagement.it>, Jeff Trawick]

  *) Make install passed a shell expanded list of header files to the
     build/install.sh script, which can only install one file at a time.
     Changed to install one header file at a time. [Justin Erenkrantz,
     Graham Leggett]

  *) Add a build script to create a solaris package. [Graham Leggett]

  *) [NetWare] Fixed some type mismatches in threadproc/netware/proc.c and
     locks/netware/thread_mutex.c that prevented APR from building with the
     latest release of the LibC SDK. [Brad Nicholes]
     
  *) Fix issue with poll() followed by net I/O yielding EAGAIN on
     Mac OS 10.4 (Darwin 8). [Wilfredo Sanchez]

Changes for APR 1.0.1

  *) Fix HUP return codes in pollset when using KQueue.
     [Paul Querna]

  *) Prevent unbounded memory use during repeated operations on a hash table.
     [Julian Foad <julianfoad btopenworld.com>

  *) Moved repository to SVN
     [Hackathon]

  *) jlibtool: Ignore '-export-symbols-regexp' option.
     [Justin Erenkrantz]

  *) fix apr_file_dup and apr_file_dup2 win32 implementations
     to create a mutex [Steve Hay <steve.hay uk.radan.com>]

  *) Makes the threads to behave like on posix. If the thread is created
     without APR_DETACH expect that the thread_join will be called, so don't
     close the handle in advance, if the thread has already finished.
     [Mladen Turk]

  *) The apr/test/Makefile.win is missing a target to build a
     readchild.exe that test is depending on but is never built.
     [Mladen Turk]

  *) Improve apr_file_gets() performance on buffered files. [Justin Erenkrantz]

  *) Win32: Fix bug in apr_socket_sendfile that interferred with
     Win32 LSPs. PR 23982 [Jan Bilek, Bill Stoddard]

  *) Win32: Fix bug tracking the file pointer on a file opened for 
     overlapped/APR_XTHREAD io. [Bill Stoddard]

Changes with APR 1.0

  *) Only install apr-$MAJOR-config and add appropriate detection code to
     find_apr.m4 (APR_FIND_APR).  [Max Bowsher <maxb ukf.net>]

  *) Remove APR_STATUS_IS_SUCCESS() macro.  [Justin Erenkrantz]

  *) apr_proc_create() on Unix: Remove unnecessary check for read 
     access to the working directory of the child process.
     PR 30137.  [Jeremy Chadwick <apache jdc.parodius.com>]

  *) Add jlibtool - enabled with '--enable-experimental-libtool' option.
     [Justin Erenkrantz]

  *) Add support for KQueue and sys_epoll to apr_pollset.  [Paul Querna]

  *) Support threading on FreeBSD 5.x where kern.osreldate >= 502102.
     [Craig Rodrigues <rodrigc crodrigues.org>]

  *) Add an RPM spec file derived from Fedora Core.
     [Graham Leggett, Joe Orton]

  *) Fix apr_threadattr_detach_set() on Mac OS X.  PR 28472.
     [INOUE Seiichiro <inoue ariel-networks.com>]

  *) Change default inter-process locking mechanisms: POSIX semaphores
     and pthread cross-process mutexes are not used by default; on 
     Solaris, fcntl locks are used by default.  [Joe Orton]

  *) Add apr_threadattr_guardsize_set() for overriding the default stack
     guard area size for created created by apr_thread_create().
     [Joe Orton]

  *) Add apr_shm_remove() function for removing a named shared
     memory segment.  [Amit Athavale <amit_athavale persistent.co.in>]

  *) Add apr_strtoff() function for converting numeric strings into 
     apr_off_t values.  [André Malo <nd perlig.de>, Joe Orton]

  *) Fix stack overflow with IPv6 apr_socket_accept() on Win32.
     PR 28471.  [inoue <inoue ariel-networks.com>]

  *) Add new functions apr_signal_block, apr_signal_unblock to block/unblock
     the delivery of a particular signal.  [Madhusudan Mathihalli]

  *) Add support for developers to use their own hashing function with
     apr_hash_make_custom.  [Ami Ganguli <hse_ami@yahoo.co.uk>]

  *) Support "large files" by default on 32-bit Unix platforms which
     implement the LFS standard.  [Joe Orton]

  *) Add apr_threadattr_stacksize_set() for overriding the default
     stack size for threads created by apr_thread_create().
     [Jeff Trawick]

  *) The whole codebase was relicensed and is now available under
     the Apache License, Version 2.0 (http://www.apache.org/licenses).
     [Apache Software Foundation]

  *) Switch to a single, top-level make. [Greg Stein]

  *) new error status APR_STATUS_IS_ENOTENOUGHENTROPY, Doxygen fixes
     [Sander Temme <sander at temme dot net]

  *) Add apr_socket_type_get() for retrieving the type (e.g., stream)
     of the socket.  [Philippe M. Chiasson]

  *) Removed deprecated interface apr_proc_other_child_check() 
     that behaved differently between win32 and unix.
     The unix behavor is now accomplished with
         apr_proc_other_child_refresh_all(APR_OC_REASON_RESTART)
     The win32 behavor is now accomplished with
         apr_proc_other_child_refresh_all(APR_OC_REASON_RUNNING)

  *) Removed apr_socket_opt_{get|set}(..., APR_SO_TIMEOUT) which
     was deprecated in favor of apr_socket_timeout_{get|set}().

     use with 32-bit ints  [Brian Pane]
