+ config.guess and config.sub. [Rainer Jung]
+
+ *) Add support for Berkeley DB 4.6 to 4.8.
+ [Arfrever Frehtes Taifersar Arahesis <arfrever.fta gmail.com>,
+ Rainer Jung]
+
+Changes with APR-util 0.9.17
+

+
+Changes with APR-util 0.9.14
+

+
+Changes with APR-util 0.9.13
+
+ *) Add support for Berkeley DB 4.5 to the configure scripts.
+ [Garrett Rooney]
+
+ *) Allow apr_queue.h to be included before other APR headers.
+ PR 40891 [Henry Jen <henryjen ztune.net>]
+
+ *) Provide folding in autogenerated .manifest files for Win32 builders
+ using VisualStudio 2005 [William Rowe]
+
+ *) Fix incorrect byte order (PR 37342) and incorrect timestamp type
+ in the fallback UUID generator used when no external UUID generator
+ is detected by APR.
+ [Max Bowsher]
+
+Changes with APR-util 0.9.12
+
+ *) Win32 / Netware - add missing apu_version.c for apu_version_string()
+ to the Windows and Netware specific builds. Unix platforms supported
+ this API since 0.9.1. [William Rowe, Brad Nicholes].
+
+Changes with APR-util 0.9.11
+
+ *) Sync get-version.sh from apr source at ./buildconf time, to correctly
+ retrieve 2 digit subversion, which broke the 0.9.10 candidate, and
+ keep any other updates in sync going forwards. [William Rowe]
+
+ *) Port apr tree change for 'make check' test/ binaries on Darwin to
+ avoid -no-install which can break the tests. [William Rowe, Joe Orton]
+
+Changes with APR-util 0.9.10
+
+ *) Minor build and runtime fixes.
+
+Changes with APR-util 0.9.9
+
+ *) Unix: No longer require an APR source directory to be available at
+ ./configure time, by making use of mkdir.sh, make_exports.awk,
+ make_var_export.awk installed to the installbuilddir by APR >= 0.9.9.
+ [Max Bowsher]
+
+ *) Stop trying to link against Berkeley DB by default. To enable use
+ of Berkeley DB users must now explicitly pass --with-berkeley-db to
+ configure, since Berkeley DB is released under a viral license that
+ requires distribution of source code for any program that uses it.
+ [Garrett Rooney]
+
+ *) Stop trying to link against GDBM by default. To enable use of GDBM
+ users must now explicitly pass --with-gdbm to configure, since GDBM
+ is licensed under the GPL.
+ [Garrett Rooney]
+
+ *) Fix VPATH builds, and symlink builds where apr and apr-util
+ reside in parallel as symlinks to directories with more explicit
+ names, e.g. apr-1.x and apr-util-1.x. This solves various breakage
+ on Solaris in particular with ./buildconf and ./configure.
+ [William Rowe]
+
+ *) Add support for Berkeley DB 4.4 to the configure scripts.
+ [Garrett Rooney]
+
+Changes with APR-util 0.9.7
+
+ *) Fix apr_rmm_realloc() offset calculation bug. [Keith Kelleman
+ <keith.kelleman oracle.com>]
+
+ *) Fix handling of a premature EOF with the FILE bucket; a new bucket
+ is not inserted for each attempt to read past EOF. PR 34708.
+ [Jeff Trawick, Joe Orton]
+
+ *) Fix build failure with non-threaded APR on AIX. PR 34655.
+ [Ryan Murray <rmurray+apache cyberhqz.com>]
+
+ *) Backport the apr_reslist_timeout_set and apr_reslist_invalidate
+ functions already in APR 1.0.x. [Paul Querna]
+
+ *) Fix linking problem on cygwin. [Max Bowsher <maxb ukf.net>]
+
+Changes with APR-util 0.9.6
+
+ *) Fix the detection of ldap.h on Solaris - it needs lber.h to be
+ defined first. [Graham Leggett]
+
+ *) Add an RPM spec file. [Graham Leggett]
+
+ *) Add a build script to create a solaris package. [Graham Leggett]
+
+ *) Add support for Berkeley DB 4.3. [Jani Averbach <jaa jaa.iki.fi>]
+
+Changes with APR-util 0.9.5
+
+ *) Guarantee and require default address alignment for block offsets
+ within segments in the apr_rmm interface. PR 29873. [Joe Orton]
+
+ *) SECURITY: CAN-2004-0786 (cve.mitre.org)
+ Fix input validation in apr_uri_parse() to avoid passing negative
+ length to memcpy for malformed IPv6 literal addresses.
+ [Joe Orton]
+
+ *) Fix build issues in paths containing symlinks. PR 8867.
+ [Joe Orton]
+
+ *) Fix corrupt output from the apr_xlate_* interfaces on AIX 4.x.
+ [Joe Orton]
+
+ *) Change the order in which ldap.h and lber.h are defined, to fix
+ a compile bug in Solaris v2.8 which requires lber.h then ldap.h.
+ PR 27379. [Andrew Connors <andy.connors idea.com>]
+
+ *) Restore support for SHA1 passwords in apr_validate_password.
+ PR 17343. [Paul Querna <chip force-elite.com>]
+
+ *) Fix DESTDIR install for bundled expat library. PR 14076
+ [David S. Madole <david madole.net>]
+
+ *) Fix occasional crash in apr_rmm_realloc(). PR 22915.
+ [Jay Shrauner <shrauner inktomi.com>]
+
+ *) Fix apr_dbm_exists() for sdbm when sizeof(int) != sizeof(size_t).
+ [Joe Orton]
+
+ *) The whole codebase was relicensed and is now available under
+ the Apache License, Version 2.0 (http://www.apache.org/licenses).
+ [Apache Software Foundation]
+
+ *) Fix xlate.c compile failure on AIX 5.2. PR 25701. [Jeff Trawick]
+
+ *) Fixed a bug in apr_rmm that would cause it to mishandle blocks of
+ a size close to the one requested from the allocator.
+ [Kevin Wang <xwang_tech yahoo.com>]
+
+Changes with APR-util 0.9.4
+
+ *) Changed apr_bucket_alloc_create() so that it uses the allocator
+ from the pool that was passed in rather than creating its own.
+ Also, the bucket_allocator is now allocated from the apr_allocator_t
+ rather than using apr_palloc(). Added apr_bucket_alloc_create_ex()
+ which takes an apr_allocator_t* directly rather than an apr_pool_t*.
+ [Cliff Woolley, Jean-Jacques Clar]
+
+ *) Added debugging consistency checks to the buckets code. Add
+ -DAPR_BUCKET_DEBUG to the build flags to enable.
+ [Cliff Woolley]
+
+ *) Make the version of the db library APU built against visible.
+ [Thom May]
+
+ *) Fix a problem with VPATH builds copying the APR rules.mk into the
+ source directory rather than the build directory. [Justin Erenkrantz]
+
+ *) SECURITY [httpd incident CAN-2003-0189] Address a thread safety
+ issue with apr_password_validate() on AIX, Linux, Mac OS X, and
+ possibly other platforms. [Jeff Trawick, Justin Erenkrantz]
+
+ *) Fix a problem with LDAP configuration which caused subsequent
+ configure tests to fail since LIBS contained LDAP libraries for
+ subsequent tests but LDFLAGS no longer included the path to such
+ LDAP libraries. [Jeff Trawick]
+
+ *) Fix a problem preventing the use of the bundled Expat when APR-util
+ is built stand-alone. [Jeff Trawick]
+
+ *) Use the same compiler and preprocessor for the APR-util config tests
+ which were used by APR. The user can override this via CC and CPP.
+ This was done all along for the actual build, but not necessarily
+ for the config tests. [Jeff Trawick]
+
+ *) Fix apr_uuid_parse() on EBCDIC machines. [Jeff Trawick]
+
+ *) Fix alignment problem when allocating memory using apr_rmm. The problem
+ showed up while trying to write a double in the memory allocated.
+ [Madhusudan Mathihalli]
+
+Changes with APR-util 0.9.3
+
+ *) Allow apr_date_parse_rfc to parse 'Sun, 06-Nov-1994 08:49:37 GMT' as a
+ valid date. [Dmitri Tikhonov <dmitri@netilla.com>]
+
+ *) Fix error in apu-config when symlinks are involved.
+ [Garrett Rooney <rooneg@electricjellyfish.net>]
+
+Changes with APR-util 0.9.2
+
+ *) Fix the APR_BUCKET_IS_foo() macros so they parenthesize their parameter.
+ This fixes compile problems with some types of parameters.
+ [Jim Carlson <jcarlson@jnous.com>]
+
+ *) Queue overwrite, we now return the item pushed, not a reference to it.
+ [Paul Marquis <PMarquis@pobox.com, Jacob Lewallen <jlwalle@cs.ucr.edu>]
+
+ *) Remove include/apr_ldap.h on distclean. PR 15592. [Justin Erenkrantz]
+
+ *) Fix race conditions in apr_queue.
+ [Jacob Lewallen <jlwalle@cs.ucr.edu>]
+
+ *) Stop buildconf copying rules.mk, copy it at configure time.
+ [Thom May]
+
+ *) Make buildconf copy rules.mk as well.
+ [Garrett Rooney <rooneg@electricjellyfish.net>]
+
+ *) Add --includedir flag to apu-config. [Justin Erenkrantz]
+
+ *) Fix brokenness in sdbm when sizeof(int) != sizeof(size_t)
+ (e.g., 64-bit AIX, 64-bit Solaris). PR 14861. [Jeff Trawick]
+
+ *) Have buildconf copy required files from apr so that apr-util can build
+ on its own. [Craig Rodrigues <rodrigc@attbi.com>]
+
+ *) Detect OpenLDAP when used with Solaris 9. PR 13427.
+ [Gary Algier <gaa@ulticom.com>]
+
+ *) Detect Berkeley DB 4.1 when compiled with --with-uniquenames
+ [Thom May]
+
+ *) Allow apu-config to work in symlinked install directories when
+ 'realpath' is available. [Justin Erenkrantz]
+
+ *) Fix bug in apr_strmatch when used with case-insensitive patterns.
+ [Justin Erenkrantz]
+
+ *) Allow apr_queue to have greater than int number of elements.
+ [Justin Erenkrantz]
+
+ *) Detect Berkeley DB 4.0 compiled with --with-uniquenames.
+ [Philip Martin <philip@codematters.co.uk>]
+
+ *) Allocate brigades from a bucket allocator rather than a pool. [Brian Pane]
+
+ *) Update with the latest APR renames [Thom May]
+
+ *) Update doxygen tags. [Justin Erenkrantz]
+
+ *) Add apr_ldap.hw for Windows build.
+ [Andre Schild <A.Schild@aarboard.ch>]
+
+ *) Add IPv6 literal address support to apr_uri_parse(), apr_uri_unparse(),
+ and apr_uri_parse_hostinfo(). PR 11887 [Jeff Trawick]
+
+ *) Add apr_brigade_writev() [Brian Pane]
+
+ *) Add support for Berkeley DB 4.1. [Justin Erenkrantz]
+
+ *) Add --bindir option to apu-config. [Justin Erenkrantz]
+
+Changes with APR-util 0.9.1
+
+ *) Add versioning infrastructure.
+ [Justin Erenkrantz]
+
+ *) Running "make check" in the toplevel directory or the test/ directory
+ will build and run all test programs. [Aaron Bannert]
+
+ *) Bug #9789 : NDBM support
+ [Toomas Soome <tsoome@muhv.pri.ee>, Ian Holsman]
+
+ *) Added a Thread safe FIFO bounded buffer (apr_queue) [Ian Holsman]
+
+ *) Changed file_bucket_setaside() to use apr_file_setaside() instead
+ of turning the file bucket into an mmap bucket. [Brian Pane]
+
+ *) Install libaprutil support libraries before installing libaprutil
+ itself, since on some platforms libaprutil is relinked during
+ make install and the support libraries need to exist already.
+ [Jeff Trawick]
+
+ *) Added a Resource List API for threadsafe access to persistent
+ and dynamically created user-defined resources. [Aaron Bannert]
+
+ *) Adopted apr-util/xlate from apr/i18n for inclusion of apr-iconv
+ as required by missing libiconv. [William Rowe]
+
+ *) Adopted apr-util/crypto/ uuid and md5 from apr. [William Rowe]
+
+ *) Look for expat in lib64 directories. [Peter Poeml <poeml@suse.de>]
+
+ *) Faster implementation of apr_brigade_puts() [Brian Pane]
+
+ *) Fixed a segfault in apr_date_parse_rfc() for some date formats
+ where it was trying to overlay a potentially static input
+ string even though it didn't really need to.
+ [Cliff Woolley, Doug MacEachern]
+
+ *) Ensure that apu-config does not print libtool libraries when
+ using --libs. [Justin Erenkrantz]
+
+ *) Added apr_bucket_file_enable_mmap() function to the bucket
+ API to let an application control whether a file bucket may
+ be turned into an mmap bucket upon read. (The default remains
+ to do the mmap, but this function lets the app prevent the
+ mmap in contexts where mmap would be a bad idea. Examples
+ include multiprocessors where mmap doesn't scale well and
+ NFS-mounted filesystems where a bus error can result if
+ a memory-mapped file is removed or truncated.) [Brian Pane]
+
+ *) Added string-matching API (apr_strmatch.h) [Brian Pane]
+
+ *) Rearrange INCLUDES so that APRUTIL_PRIV_INCLUDES is always
+ first. [Garrett Rooney <rooneg@electricjellyfish.net>]
+
+ *) Add --old-expat option to apu-config to allow users of apr-util to
+ determine what expat it should expect to be installed. If the
+ flag is set to yes, it should include xmlparse.h. If it is set to
+ no, it should include expat.h. [Justin Erenkrantz]
+
+ *) Fix exporting of includes in apu-config. [Justin Erenkrantz]
+
+ *) Change bucket brigades API to allow a "bucket allocator" to be
+ passed in at certain points. This allows us to implement freelists
+ so that we can stop using malloc/free so frequently.
+ [Cliff Woolley, Brian Pane]
+
+ *) add apr_rmm_realloc() function
+ [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
+
+ *) renames: apr_ansi_time_to_apr_time becomes apr_time_ansi_put
+ ap_exploded_time_t becomes apr_time_exp_t
+ [Thom May <thom@planetarytramp.net>]
+
+ *) Add detection support for FreeBSD's expat and expat2 ports.
+ [Justin Erenkrantz]
+
+ *) Deprecate check_brigade_flush(), which had several nasty bugs, and
+ which was causing apr_brigade_write()'s logic to be less than obvious.
+ Everything is now done in a slightly rearranged apr_brigade_write().
+ [Cliff Woolley]
+
+ *) Don't add /usr/include to the INCLUDES variable on expat's account.
+ [Joe Orton <joe@manyfish.co.uk>]
+
+ *) Remove the autoconf 2.5x cache directory in buildconf.
+ [Joe Orton <joe@manyfish.co.uk>]
+
+ *) BerkleyDB should NULL out the key if it is @EOF in vt_db_nextkey
+ [Ian Holsman]
+
+ *) Add ability to natively fetch and split brigades based on LF lines.
+ [Justin Erenkrantz]
+
+ *) add --with-berkeley-db=DIR & --with-gdbm configure flags
+ [Ian Holsman/Justin Erenkrantz]
+
+ *) Fix expat detection to recognize installed versions.
+ [Eric Gillespie, Jr. <epg@pretzelnet.org>]
+
+ *) Add find_apu.m4 to allow third-party programs that use APR-util
+ to have a standard m4 macro for detection. [Justin Erenkrantz]
+
+ *) Add apu-config - a shell script to allow third-party programs
+ easy access to APR configuration parameters. [Justin Erenkrantz]
+
+ *) Add GMT offset calculation to apr_date_parse_rfc().
+ [Justin Erenkrantz]
+
+ *) Introduce the apr_rmm api, to allow relocatable memory management
+ of address-independent data stores, such as shared memory.
+ [William Rowe]
+
+ *) Rework and fix VPATH-build support. [Justin Erenkrantz]
+
+ *) Add support for Berkeley DB4. [Justin Erenkrantz]
+
+ *) Improve testdbm help. [Justin Erenkrantz]
+
+ *) Improve autoconf detection of DBMs. [Justin Erenkrantz]
+
+ *) BerkeleyDBM v2 now checks minor level for cursor ops [Ian Holsman]
+
+ *) Reading a file bucket bigger than APR_MMAP_LIMIT (4MB) now yields
+ a string of 4MB mmap buckets, rather than a string of 8KB heap buckets
+ plus a 4MB mmap bucket. To accomodate this, the mmap bucket destroy
+ function explicitly deletes the apr_mmap_t after last reference
+ to avoid having too much of a large file mapped at once if possible.
+ [Cliff Woolley]
+
+ *) Multi-DBM support (via apr_dbm_open_ex). [Ian Holsman]
+
+ *) Use apr_mmap_dup in mmap_setaside(). [Brian Pane <bpane@pacbell.net>]
+
+ *) Dropped the "w" parameter from apr_bucket_heap_create() and
+ apr_bucket_heap_make(). That parameter was originally intended
+ to return the amount of data copied into the bucket, but it
+ ended up being unnecessary because that amount is invariant from
+ the size of the data and is available as b->length in the
+ resulting bucket anyway. [Cliff Woolley]
+
+ *) Fix Makefile conversion for BSD/OS. [Cliff Woolley]
+
+ *) Use APR_XtOffsetOf instead of offsetof() in the ring macros for
+ portability. [Cliff Woolley]
+
+ *) We now create exports.c and export_vars.h, which in turn create
+ exports.c. From this we generate two more files with different
+ purposes: aprutil.exp - list of exported symbols; and exports.lo
+ (exports.o) - an object file that can be linked with an executable
+ to force resolution of all apr-util symbols. [Aaron Bannert]
+
+ *) Fix Berkley DBM support [Ian Holsman <ianh@apache.org>]
+
+ *) Fix apr_brigade_vprintf so that it can handle more than
+ 4k of data at one time. [Cody Sherr <csherr@covalent.net>]
+
+ *) prefix UNP_* flags with APR_URI_
+
+ rename:
+ apr_uri_components -> apr_uri_t
+ apr_uri_unparse_components -> apr_uri_unparse
+ apr_uri_parse_components -> apr_uri_parse
+ apr_uri_parse_hostinfo_components -> apr_uri_parse_hostinfo
+
+ s/APU_URI_/APR_URI_/g
+ [Perl]
+
+ *) Landed the link-to-LDAP to the build process, and the LDAP v2/v3
+ compatibility functions.
+ [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
+
+ *) Fix URI unparse function to handle the case where it would place a @
+ when both the username and password were present but omitted.
+ [Jon Travis <jtravis@covalent.net]
+
+ *) Added apr_xml_parse_file() routine and a testxml program.
+ [Ian Holsman <ianh@cnet.com>]
+
+ *) Extend apr_bucket struct to add a pointer to a function used
+ to free the bucket. This change enables custom buckets to
+ completely specify how they are to be allocated and freed.
+ Before this change, custom buckets were required to use the
+ same memory allocation scheme as the standard APR buckets.
+ [Saeid Sakhitab, Bill Stoddard, Cliff Woolley, Roy Fielding]
+
+ *) Install Expat when installing APR-util. [Justin Erenkrantz]
+
+ *) Make APR-util configure script rely on APR. This removes the locally
+ generated copy of libtool and uses the one in APR. Fix up how we
+ call the expat configure script. Generate config.nice file.
+ [Justin Erenkrantz]
+
+ *) The apr_bucket lengths are now consistently apr_size_t, while any
+ apr_brigade lengths (short of a read) are consistently apr_off_t.
+ This is required for APR_HAS_LARGE_FILES handling. [William Rowe]
+
+ *) apr_bucket_file_create() and apr_bucket_file_make() now take a pool
+ parameter which is the pool into which any needed data structures
+ should be created during file_read(). This is used for MMAPing the
+ file and reopening the file if the original apr_file_t is in XTHREAD
+ mode. [Cliff Woolley]
+
+ *) apr_brigade_partition() now returns an apr_status_t. [Cliff Woolley]
+
+ *) Add MD4 implementation in crypto. [Sander Striker, Justin Erenkrantz]
+
+ *) Moved httpd 2.0.18's util_date to apr_date and enhanced its parsing
+ capabilities. [Justin Erenkrantz]
+
+ *) Moved httpd 2.0.18's util_uri to apr_uri and name-protected its
+ symbols and functions. [Justin Erenkrantz, Roy Fielding]
+
+ *) Rename field "private" in struct apr_xml_elem to "priv" for C++
+ compatibility. PR #7727 [Joshua MacDonald <jmacd@cs.berkeley.edu>]
+
+ *) Make APR_IMPLEMENT_EXTERNAL_HOOK_BASE generate a
+ ${namespace}_hook_get_${hookname} function to fetch the
+ list of registered hooks [Doug MacEachern]
+
+ *) Allow LTFLAGS to be overridden by the configure command-line
+ (default="--silent") and introduce LT_LDFLAGS. [Roy Fielding]
+
+ *) Add APR_SHARELOCK support to apr_sdbm_open(), locking read operations
+ with a shared lock and all write ops with an excl lock. [Will Rowe]
+
+ *) Namespace protect apr_sdbm, and normalize the return values (including
+ the apr_sdbm_fetch, apr_sdbm_firstkey and apr_sdbm_nextkey functions).
+ Normalized the get/clear error function names, and stores the actual
+ apr error for apr_sdbm_error_get. [Will Rowe]
+
+ *) Introduce an apr_fileperms_t argument to apr_dbm_open(). [Will Rowe]
+
+ *) Removed apr_bucket_do_create() macro, which was causing warnings
+ about unreachable code in some compilers (notably MSVC). What
+ used to be done by this macro is now done inline in the various
+ apr_bucket_foo_create() functions. [Cliff Woolley]
+
+ *) Make clean, distclean, and extraclean consistently according to the
+ Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
+
+ *) Migrate the --disable-libtool changes from APR to APR-util.
+ This cleans things up, and allows more flexibility when building
+ programs. [Ryan Bloom]
+
+ *) Allow APR-util to be compiled without libtool. The default is
+ to use libtool, but it can turned off with --disable-libtool
+ on the configure command. [Ryan Bloom]
+
+ *) Repair calling convention for apr_register_optional_fn to
+ eliminate GP fault on Win32. [William Rowe]
+
+ *) Substantial changes to correct linkage and declarations for
+ generic hooks on dso architectures. [Ben Laurie, Will Rowe]
+
+ *) apr_bucket_shared_destroy() now returns a boolean value.
+ [Cliff Woolley]
+
+ *) We have to initialize the heap buckets to the correct length.
+ we were seeing heap buckets with 17 chars in them reporting
+ a length of 9017, because they were initialized to the amount
+ of memory allocated, instead of the amount of memory used.
+ This was only an issue for heap buckets created by the
+ apr_brigade_* functions. [Ryan Bloom]
+
+ *) apr_bucket_init_types() and apr_bucket_insert_type() have been
+ removed... they're not needed anymore. [Cliff Woolley]
+
+ *) The apr_bucket_shared and apr_bucket_simple structures have been
+ removed as an API simplification/optimization. This should be
+ transparent outside APR-util except to callers who attempt to
+ directly manipulate the buckets' internal structure (which is
+ not recommended anyway) and to callers who create their own
+ bucket types. [Cliff Woolley]
+
+ *) apr_bucket_simple_split() and apr_bucket_simple_copy() are now
+ exported functions, which could be helpful in implementing
+ external bucket types. [Cliff Woolley]
+
+ *) The third parameter to apr_bucket_shared_make() is now
+ 'apr_off_t length' rather than 'apr_off_t end', since the
+ end usually had to be computed by the caller and all we
+ really want is the length anyway. [Cliff Woolley]
+
