+ edge cases. [William Rowe]
+
+Changes for APR 1.2.6
+
+ *) Fully test the detected libuuid or libc based uuid_create or
+ uuid_generate function against the detected uuid.h, uuid/uuid.h,
+ or sys/uuid.h (using only the first-found .h examined in that order)

+ on Win32.
+ [Philip Martin <philip codematters.co.uk>

+ when one or more of them are both readable and writable.
+ [Dror Shilo <Dror.Shilo ericom.com>, Gerry <gerry everythingsucks.co.uk>]
+
+ *) Fix apr_file_seek() to catch write failures when flushing

+ set when TCP_DEFER_ACCEPT was set. [Brian Pane]
+
+ *) Allow TCP_NODELAY and TCP_CORK to be set concurrently on
+ Linux 2.6 and later. [Joe Orton]
+
+ *) Fix apr_socket_addr_get(,APR_REMOTE,) after a non-blocking
+ connection is completed. PR 32737. [Joe Orton]

+ PR 34053. [Paul Querna]
+
+ *) 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

+ [Stas Bekman]
+
+ *) Added apr_os_uuid_get() support for Linux via libuuid and for modern
+ BSDs which have uuid_create as part of their libc. [Paul Querna]
+
+ *) Added Solaris 10 'Event Ports' as a backend for APR Pollset. This
+ backend also supports the APR_POLLSET_THREADSAFE flag. [Paul Querna]
+
+ *) Added the APR_POLLSET_THREADSAFE flag. This allows multiple threads
+ to call the Pollset Add or Remove functions in a thread safe manner.
+ Currently only EPoll and KQueue support this flag. [Paul Querna]
+
+ *) Split poll/unix/poll.c into separate files for each Poll or Pollset
+ implementation. [Paul Querna]

+
+ *) The whole codebase was relicensed and is now available under

+ [Apache Software Foundation]
+
+ *) Define apr_off_t as long rather than as off_t on platforms with a
+ 32-bit off_t to prevent incompatibility with packages such as
+ Perl which redefine the size of off_t via _FILE_OFFSET_BITS on
+ some platforms. [Ben Reser <ben reser.org>]
+
+ *) apr_socket_connect(): allow app to make subsequent call on
+ non-blocking socket. [Jeff Trawick]
+
+ *) Add apr_os_pipe_put_ex(), which allows the caller to tell APR
+ to establish a cleanup on the pipe. [Jeff Trawick, Brad Nicholes]
+
+ *) Fix make_exports.awk to work with apr-iconv. [Justin Erenkrantz]
+
+Changes with APR 0.9.4

+ [Mike Pilato <cmpilato collab.net>, William Rowe]
+
+ *) Work around a bug in Darwin when calling getnameinfo() on IPv4-mapped
+ IPv6-addresses. [Colm MacCárthaigh <colm stdlib.net>, Jeff Trawick,

+
+ *) Add apr_temp_dir_get() for getting the most suitable temp directory

+ [Colm MacCárthaigh <colm stdlib.net>, Justin Erenkrantz]
+
+ *) Change the behavior of unix process 'trylock's to return

+
+ *) Fix a subtle race where the ownership of a unix nested
+ thread lock could be corrupted when the prior owner released

+ [Joe Schaefer <joe+gmane sunstarsys.com>, Brian Pane]

+ *) Win32: Adopt Brian Havard's OS/2 rwlock implementation for
+ Windows [Marc Adkins, Bill Stoddard]
+
+ *) Add apr_proc_mutex_lockfile() for retrieving the name of the
+ file associated with a mutex. [Jeff Trawick]
+
+ *) Don't require the lock file name to be passed into
+ apr_proc_mutex_child_init() or apr_global_mutex_child_init().
+ This allows child init to work when the lock file was a temp
+ file created by APR. (The problem only occurred with flock-
+ based mutexes.) [Jeff Trawick]
+
+ *) When using a temporary file for flock- and fcntl-based mutexes,
+ don't let the file be deleted on close. For flock-based mutexes,
+ this corrects a fatal problem, since the file would disappear
+ when a program was spawned and cleanup-for-exec was performed,
+ and a subsequent attempt to perform child process mutex
+ initialization would fail. For fcntl-based mutexes, this was a
+ very minor issue that resulted in a failing unlink() when the
+ file was closed, since fcntl lock initialization always removes
+ the file immediately. [Jeff Trawick]
+
+ *) When writing to pipes with a timeout set, handle the situation
+ where the kernel says the pipe is writable but an attempt to
+ write <= PIPE_BUF bytes gets EAGAIN. APR will now write whatever
+ data will fit. APR applications that relied on the atomic nature
+ of relatively small pipe write requests may be affected.
+ PR 20295 [Mark Street <mark faime.demon.co.uk>, Jeff Trawick]
+
+ *) Define _THREAD_SAFE for all compilations on AIX. Previously
+ those of us who used the vendor compiler had it defined
+ implicitly and others did not. The difference became obvious
+ with the recent thread safety fixes to apr_password_validate().
+ PR 20420 [Jeff Trawick]
+
+ *) For apr_proc_detach(APR_PROC_DETACH_FOREGROUND), don't treat
+ a setsid() failure as fatal, as the usual cause is that the
+ caller is already a process group leader. PR 18519
+ [Jeff Trawick]
+
+ *) Fix some problems with non-blocking socket handling on unix
+ that resulted in infinite timeouts being used for non-blocking
+ sockets with apr_socket_connect() and some read/write calls.
+ [Jeff Trawick]
+
+ *) Fix a bug in socket timeout handling on unix that left the
+ socket non-blocking after disabling the timeout.
+ [Jacob Craig Lewallen <jlewalle cs.ucr.edu>]
+
+ *) Added flag APR_FILE_ATTR_HIDDEN for manipulating the "hidden"
+ file attribute on Windows and OS/2. [Branko Cibej]
+
+ *) SECURITY [CAN-2003-0245]: Fixed a bug that could be triggered
+ remotely through mod_dav and possibly other mechanisms, causing
+ an Apache child process to crash. The crash was first reported
+ by David Endler <DEndler iDefense.com> and was researched and
+ fixed by Joe Orton <jorton redhat.com>. Details will be released
+ on 30 May 2003.
+
+ *) apr_proc_wait(): Handle interrupted waitpid(2) calls by calling
+ it repeatedly until it succeeds or fails with errno other than
+ EINTR. This hides this UNIX-specific behavior from APR clients.
+
+ *) Removed the solaris-specific atomic code, due to licence
+ concerns (it was MPL 1.0, and the author could not be contacted)
+ [Ian Holsman]
+
+ *) apr_file_gets(): Return APR_SUCCESS if any characters are
+ returned. Any I/O errors or EOF will be reported on the
+ next call. Callers that are coded to expect returned
+ data + APR_EOF when there is no final newline are affected
+ by this change. [Jeff Trawick]
+
+ *) apr_proc_create() on Unix: Make the APR_SHELLCMD mode work
+ when there is more than one program argument passed in.
+ [Jeff Trawick]
+
+ *) Add --cc and --cpp flags to apr-config. [Jeff Trawick]
+
+ *) Don't segfault trying to close a file in error paths of flock
+ and fcntl mutex creation. PR 19036 [Jeff Trawick]
+
+ *) Add %pT support to apr_snprintf() for printing an apr_os_thread_t.
+ [Jeff Trawick]
+
+ *) Add APR_TCP_NODELAY_INHERITED & APR_O_NONBLOCK_INHERITED to apr.hw
+ [Allan Edwards]
+
+ *) Add APR_UINT64_T_HEX_FMT. [Jeff Trawick]
+

+ *) Note: We are in the process of deprecating the apr_lock.h API.
+ The new and improved lock/synchronization APIs now reside
+ in apr_thread_mutex.h, apr_proc_mutex.h, apr_thread_rwlock.h,
+ and apr_thread_cond.h. [Aaron Bannert]
+
+ *) Enable autoconf 2.52{f,g} build support.
+ [Blair Zajac <blair@orcaware.com>]
+
+ *) Added new functions for atomic operations. These are experimental
+ at the moment, so use in apps is discouraged [Ian Holsman]
+

+ and apr_file_open_stdxxx() fns. [William Rowe]
+
+ *) Begin implementation of the WinCE port.
+ [Mladen Turk <mturk@mappingsoft.com>]
+
+ *) Disable SHMEM_MMAP_ZERO on HPUX 11.x where it is not supported.
+ Use SHMEM_SHMGET_ANON instead. [Aaron Bannert]
+
+ *) Fix a few attempts to add to a void * ptr in the Unix shared
+ memory support code. PR #9710 Per Ekman [pek@pdc.kth.se]
+
+ *) In the Linux apr_sendfile(), fix the types of some parameters
+ to apr_send() and apr_recv(). Breakage was seen in 64-bit mode
+ on s/390. PR #9712 [Neale.Ferguson@SoftwareAG-usa.coom]
+
+ *) added APR_PROGRAM_ENV and APR_PROGRAM_PATH options for starting
+ processes via apr_proc_create() [Greg Stein]
+
+ *) Deprecated apr_pool_free_blocks_num_bytes() [Sander Striker]
+
+ *) Add --enable-pool-debug to make it easier for people to
+ enable pool debug mode. Removed the APR_POOL_DEBUG_VERBOSE
+ define that was previously being used. [Sander Striker]
+
+ *) Changed the apr_file_dup2() function prototype. It can only
+ take and reuse an apr_file_t*, and will no longer create one
+ if *new_file == NULL (use apr_file_dup() for that). [Aaron Bannert]
+
+ *) Implemented name-based shared memory on Unix. [Aaron Bannert]
+
+ *) Fix spelling mistakes in APRDesign.

+ *) Make sure to pre-mark anon SysV shared memory segments as
+ removed. [Jim Jagielski]
+
+ *) Add --with-efence to allow usage of Electric Fence.

+
+ *) Updated the pools debug code. Check if a pool is still
+ valid on the most common apr_pool_xxx functions.
+ Fix the way APR_POOL_DEBUG_VERBOSE was using stderr.
+ Make the output somewhat nicer in this debug mode. [Sander Striker]
+
+ *) Add new define APR_POOL_DEBUG_VERBOSE which spits out info
+ about pool creation/destruction [Ian Holsman]
+
+ *) Fix GMT offset adjustments for platforms that do not have native
+ GMT offset adjustments. [Jon Travis <jtravis@covalent.net>]
+
+ *) Add new apr_shm_t API and remove old apr_shmem_t API. The new
+ API handles both anonymous and name-based shared memory. Anonymous
+ shared memory segments are only usable on systems with process
+ inheritance, and so the new API with name-based segments is
+ usable on platforms like Win32. [Aaron Bannert and William Rowe
+ with much help from Justin Erenkrantz and Sander Striker]
+
+ *) Add --with-egd to support EGD-compatible entropy gatherers for
+ those platforms without native support. [Justin Erenkrantz]
+
+ *) apr_lock_create() and apr_proc_mutex_create() now have an
+ additional parameter for specifying the lock mechanism.
+ apr_lock_create_np() and apr_proc_mutex_create_np() have been
+ removed. [Jeff Trawick]
+
+ *) Change the prototype of apr_thread_exit() so that the apr_status_t
+ is no longer a pointer. It was difficult and sometimes hazardous
+ to return a apr_status_t* at times, and this allows us to return
+ the APR_* error codes directly. [Aaron Bannert]
+
+ *) Add apr_sockaddr_equal() for comparing APR sockaddrs.
+ [Jeff Trawick]
+
+ *) Win32: apr_sendfile() should return APR_ENOTIMPL if
+ oslevel < WINNT. [Bill Stoddard]
+
+ *) Put new pools code in place which allows applications to
+ switch off locking on pools operations in case a pool is
+ guaranteed to never being used in more than one thread
+ at the same time. We've seen a significant performance
+ improvement over the old code. [Sander Striker]
+
+ *) Add apr-config - a shell script to allow third-party programs

+
+ *) Fix a problem in Unix apr_file_dup() which caused 0 to be returned
+ by the first read. [Stas Bekman <stas@stason.org>]
+
+ *) Fix a buglet that caused APR_FILE_BASED_SHM to be set inadvertently

+
+ *) Speed up apr_table operations by using a cache/checksum and a
+ red-black tree in the overlay.
+ [Brian Pane <bpane@pacbell.net>, Cliff Woolley]
+
+ *) Speed up apr_pool_userdata_set[n] by letting hash_set figure out

+
+ *) Fix bug in Darwin DSO code. [Sander Temme]
+
+ *) Fix apr_setup_signal_thread() to grab the right error code from

+ sigprocmask() in lieu of pthread_sigmask(). [Jeff Trawick]
+
+ *) Fix the Unix HAVE_POLL flavor of apr_poll_socket_mask() so that
+ it doesn't segfault. Avoid some wasted storage in a poll-related
+ APR structure. [INOUE Seiichiro <inoue@ariel-networks.com>]
+
+ *) Fix apr_setup_signal_thread() so that threads don't block
+ synchronous signals (e.g., SIGSEGV). It is a programming error
+ to do so, and some platforms (e.g., Solaris, AIX) don't call any
+ registered signal handler when such signals are blocked.
+ [Jeff Trawick]
+
+ *) Change the apr_table_elts macro so that it provides access via
+ a const pointer instead of a non-const pointer.
+ [Brian Pane <bpane@pacbell.net>]
+
+ *) Use strerror_r() where available, since strerror() isn't always
+ thread-safe. Example systems where strerror() isn't thread-safe:
+ Linux+glibc, AIX [Jeff Trawick]
+
+ *) Fix some file cleanup problems in apr_proc_create() which could
+ result in the pipes for stdin/stdout/stderr being closed
+ immediately. [Jeff Trawick]
+
+ *) New functions apr_hash_[merge|copy], change to overlay fn
+ so that it calls merge, which does a inline iteration instead
+ of calling the iterator function. [Brian Pane <bpane@pacbell.net>]
+
+ *) Introduce the apr_pool_userdata_setn() variant that doesn't
+ strdup the key. Allows both the _setn() and _set() variant to
+ accept NULL for the cleanup. [Brian Pane <bpane@pacbell.net>]
+
+ *) Re-vamp the apr_proc_wait and apr_proc_wait_all functions. We
+ now return the exit code from the program and a reason that the
+ program died, either normal exit or signalled.
+ [Jeff Trawick and Ryan Bloom]
+
+ *) Implement portable accessors for proc mutex. These are equivalent
+ to apr_os_lock_get/set, but they work for apr_proc_mutex_t types
+ instead. [Aaron Bannert]
+
+ *) Added a new parameter to apr_thread_mutex_init(). Now, by default,
+ thread mutexes are not nested (sometimes called "recursive"). To
+ enable nested mutexes, a flag must be passed to the init script.
+ Non-nested mutexes are much faster than nested ones.
+ [Aaron Bannert]
+
+ *) read_with_timeout in apr/file_io/win32/readwrite.c incorrectly
+ returned APR_SUCCESS instead of APR_EOF when PeekNamedPipe failed
+ and the result from GetLastError() was ERROR_BROKEN_PIPE. Because
+ of this, the pipe wasn't closed as soon as it could be.
+ [Tim Costello <tim.costello@zcmgroup.com.au>]
+
+ *) Fix a problem in the Win32 pipe creation code called by
+ apr_proc_create(): It didn't register cleanups for either the
+ read or the write ends of the pipe, so file handles (and event
+ handles for pipes with asynchronous I/O mode set) are never
+ closed. [Tim Costello <tim.costello@zcmgroup.com.au>]
+
+ *) Add support for QNX 6. [J.T. Conklin <jtc@acorntoolworks.com>]
+
+ *) 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: apr.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 symbols. [Aaron Bannert]
+
+ *) Add the apr_thread_cond_timedwait function to the condition
+ variable API. [Aaron Bannert]
+
+ *) Fixed apr_file_mktemp on systems without mkstemp (Win32, etc).
+ [Mladen Turk, Cliff Woolley]
+
+ *) Fix a segfault in apr_poll_clear on Unix. Also fix the logic
+ for the case where there are multiple events ORed together in
+ the events list. [Jamshid Mahdavi <mahdavi@volera.com>]
+
+ *) Files opened on Unix with the flag APR_DELONCLOSE are now
+ not unlinked until they are actually closed, rather than as
+ soon as they're opened. The old approach worked but made
+ handling temp files harder. [Cliff Woolley]
+
+ *) Fix potential segfault when closing a file on Unix. If
+ apr_file_close() was called and it failed, it would not
+ deregister the file cleanup. Therefore the cleanup would
+ be run again later on a now-invalid descriptor. [Cliff Woolley]
+
+ *) Introduce apr_pool_lock for debugging, in combination with
+ ALLOC_USE_MALLOC + DEBUG_WITH_MPROTECT. Only implemented
+ on Win32 today, very effective for debugging pool constness.
+ [William Rowe]
+
+ *) Optimize apr_pstrcat by caching lengths of first 6 strings
+ [Brian Pane <bpane@pacbell.net>]
+
+ *) Add pool accessors to the apr_thread_mutex_t datatype.
+ [Aaron Bannert <aaron@clove.org>]
+
+ *) Add the apr_file_mktemp function. This creates and opens a
+ temporary file, for use by the program. This file is created
+ delete_on_close. The initial implementation only works on
+ Unix, but Windows is coming soon. [Ryan Bloom]
+
+ *) Make the unix version of apr_proc_wait_all_procs a simple wrapper
+ around apr_proc_wait, and which extracts the exit code from the
+ status returned by waitpid.
+ [Kevin Pilch-Bisson <kevin@pilch-bisson.net>]
+
+ *) Add process locking API to APR. [Aaron Bannert <aaron@clove.org>]
+
+ *) Add condition variables for Windows. [Ryan Bloom]
+
+ *) Add condition variables to the APR set of locking functions.
+ This does Unix, and provides stubs for all other platforms.
+ [Aaron Bannert <aaron@clove.org>]
+
+ *) Don't search for IPv6 names in apr_sockaddr_info_get() if the
+ application doesn't specify the family (i.e., the application
+ passes in AF_UNSPEC) and APR isn't built with IPv6 support.
+ [Jeff Trawick]
+
+ *) Fix the API for the apr_proc_create() call on Win32. Several
+ bad assumptions are gone, including a mismatch between unix and
+ win32, where win32 was defaulting to create detached. Also fixes
+ the apr_proc_t's pid member to a real pid (identity that works
+ across processes) instead of the handle (which is a new hproc
+ member value.) [William Rowe]
+
+ *) Modify the external apr_filepath_get() fn to take a flags arg,
+ currently only for APR_FILEPATH_NATIVE. This returns c:\foo
+ format on Win32, and should do the same on OS2, or sys\vol:\foo
+ on Netware. Primarily for internals, but possibly useful to
+ others (and it mirrors some of the other apr_filepath_*() calls.)
+ [William Rowe]
+
+ *) Add the new thread read/write lock API to APR.
+ [Aaron Bannert <aaron@clove.org>]
+
+ *) Add the new thread mutex lock API to APR.
+ [Aaron Bannert <aaron@clove.org>]
+
+ *) Cache GMT offset on platforms that don't store it in the tm struct.
+ This offset is normalized to be independent of daylight savings
+ time. [Brian Pane <bpane@pacbell.net>]
+
+ *) Initial support for cygwin. [Stipe Tolj <tolj@wapme-systems.de>]
+
+ *) Fix a problem with buffered files on Unix. [Brian Havard]
+
+ *) Fix the bungling of getaddrinfo() error codes. [Jeff Trawick]
+
+ *) Add an apr_thread_once function to APR. This allows a
+ program to ensure that a function is only called once.
+ [Ryan Bloom]
+
+ *) APR Documentation is now in Doxygen format.
+ [Ian Holsman]
+
+ *) Get apr_ungetc() to work with buffered files on Unix.
+ [Jeff Trawick]
+
+ *) Fixed apr_filepath_root on Unix [William Rowe, Cliff Woolley].
+
+ *) Rename XtOffset to APR_XtOffset. This namespace protection
+ is important to keep from conflicting with other packages.
+ [Perl]
+
+ *) Introduce a new --disable-ipv6 option to disable IPv6 support.
+ [Sterling Hughes <sterling@designmultimedia.com>, Jeff
+ Trawick]
+
+ *) Fix the new shared memory code. We need to pass a pointer to
+ an apr_file_t to apr_file_open. Also, apr_os_file_get returns
+ a status value, not the OS file descriptor. [Ryan Bloom]
+
+ *) Fix the new shared memory configure script. The APR_DECIDE
+ macros go in order, so the last set of dependancies that are
+ met are the ones used. That means that when using those macros,
+ options should be listed with the least desirable option first,
+ and the most desirable last. The new shared memory routines did
+ the opposite, so we chose the wrong shared memory option on Linux.
+ [Ryan Bloom]
+
+ *) Move the necessary shared memory code from MM into APR and remove
+ our dependency upon MM. [Justin Erenkrantz]
+
+ *) Get apr_lock_file and apr_unlock_file working on Windows 9x.
+ [Mladen Turk, Bill Stoddard]
+
+ *) Make all APR pools be allocated out of the permanent pool.
+ This brings APR pools back to a tree structure. There are
+ no longer any way to create a pool that is not a decendant
+ of the permanent_pool. [Ryan Bloom]
+
+ *) Wrap all functions in APR_DECLARE macro.
+ [Sterling Hughes <sterling@designmultimedia.com>]
+
+ *) Non-blocking connects shouldn't be calling connect a second
+ time. According to Single Unix, a non-blocking connect has
+ succeeded when the select pops successfully. It has failed
+ if the select failed. The second connect was causing 502's
+ in the httpd-proxy. [John Barbee barbee@veribox.net]
+
+ *) Fix apr_dir_rewind() for Win32 to avoid returning a bogus error.
+ [Jeff Trawick, William Rowe]
+
+ *) Detect required libraries first. This minimizes the libraries
+ needed in apr_hints.m4. [Justin Erenkrantz]
+
+ *) Support the AIX, glibc2, and Solaris variants of gethostby{name|addr}_r.
+ Use gethostbyaddr_r function when available.
+ [Sterling Hughes <sterling@designmultimedia.com>]
+
+ *) Add new socket option, APR_INCOMPLETE_READ, that should be
+ set when you expect the first non-blocking read to fail with
+ EAGAIN. Setting APR_INCOMPLETE_READ prior to calling apr_read
+ will cause select() to be called first to wait for bytes
+ to read. [Brian Pane, Dean Gaudet]
+
+ *) Better installation. This makes us install the APRVARS file,
+ as well as MM. [Ryan Bloom]
+
+ *) Provide new number conversion functions apr_itoa, apr_ltoa, and
+ apr_off_t_toa, and inline code in inet_ntop4, to reduce CPU
+ consumption. [Brian Pane]
+
+ *) Updated APR to pass the thread worker_function prototype
+ (apr_thread_start_t) two parameters, the apr private data
+ (apr_thread_t*) and the application private data (void*).
+ Applications' worker_thread() routines may use apr_thread_pool_get
+ to access the pool (implemented using APR_POOL_*_ACCESSOR() macros.)
+ [Aaron Bannert <aaron@ebuilt.com>]
+
+ *) Add Solaris 8's sendfilev() support. This requires the following
+ patches from Sun: 111297 (Sparc), 111298 (x86). You'll need the
+ other patches listed in the patch description. [Justin Erenkrantz]
+
+ *) Close file descriptor when we are done with fcntl or flock-based
+ cross-process lock. Otherwise, we leak descriptors.
+ [Justin Erenkrantz]
+
+ *) Fix a possible data corruption problem with the use of getpwnam_r() on
+ all platforms where that function is used.
+ Use getpwnam_r() and getgrgid_r() instead of getpwnam() and getgrgid()
+ with threaded builds on glibc (2.1, at least) to avoid thread safety
+ issues. [Jeff Trawick]
+
+ *) Added apr_lock_tryacquire. It will attempt to acquire the lock, but
+ will not block if it can not acquire the lock. Returns APR_EBUSY if
+ acquistion can not happen. [Justin Erenkrantz]
+
+ *) Added an inherit flag to apr_socket_create and other socket creation
+ functions. This allows APR programs to specify that a socket should
+ be passed to any child processes that are created. The inherit flag
+ is only meaningful if programs use apr_process_create(). This
+ also adds a couple of macros that allow APR types to set and unset
+ the inherit flag. [Ryan Bloom]
+
+ *) apr_connect()on Windows: Handle timeouts and returning the proper
+ status code when a connect is in progress. [Bill Stoddard]
+
+ *) apr_connect() on Unix: Handle EINTR during connect(). Handle timeouts.
+ [Jeff Trawick]
+
+ *) Handle the weird case where getpwnam() returns NULL but errno is zero.
+ [Jeff Trawick]
+
+ *) Add apr_file_flags_get() which returns the flags that were originally
+ passed in to apr_file_open(). [Cliff Woolley]
+
+ *) Added APR_HAS_XTHREAD_FILES macro that indicates whether or not the
+ platform handles files opened in APR_XTHREAD mode natively. Currently
+ only Win32 has such native support. [Cliff Woolley]
+
+ *) Fix gmt offset handling on Solaris. Apache log messages now show
+ local time again. PR #7902 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
+
+ *) apr_pstrcat() optimizations [Doug MacEachern, Jeff Trawick]
+
+ *) Make the apr_pool_is_ancestor logic public. This is required for

+ in that function debug only. [Ryan Bloom]
+
+ *) Clean up Win32 locks when the pool goes away.
+ [Justin Erenkrantz, Jeff Trawick]
+
+ *) Implement apr_get_home_directory for Win32. [William Rowe]
+
+ *) Complete the implementation of LARGEFILE support on Win32, although
+ the mmap semantics still need a touch of work. [William Rowe]
+
+ *) Fix the APR_XTHREAD support, and apr_sendfile mechanics, so we can
+ handle cross-threaded file handles on Win32. [William Rowe]
+
+ *) Implement APR_READWRITE locks on Unix with POSIX rwlocks.
+ Introduce new apr_lock_acquire_rw() function which takes in
+ APR_READER or APR_WRITER. [Justin Erenkrantz]
+
+ *) Add apr_open_stdin. This mirrors apr_open_stderr, except it works
+ on stdin. [Aaron Bannert <abannert@ebuilt.com>]
+
+ *) Add apr_strtok(), a thread-safe flavor of strtok() which has the
+ same interface as strtok_r(). [Jeff Trawick]
+
+ *) Add other child support to Win32 [Bill Stoddard]
+
+ *) Other-child registrations are automatically removed when the
+ associated pool is destroyed. This avoids garbage in the list
+ of registrations when a pool with a registration is freed.
+ [Jeff Trawick]
+
+ *) Allow LTFLAGS to be overridden by the configure command-line

+ Luke Kenneth Casson Leighton <lkcl@samba-tng.org>
+ Sander Striker <striker@samba-tng.org>
+ [David Reid]

+ Use set_h_errno() instead. PR #7651 [Jeff Trawick]
+
+ *) Add the test and build directories (when present) to the recursive
+ make process, being sure that they are run last. test is only done
+ recursively for make *clean targets. [Roy Fielding]
+
+ *) Make the apr_mmap_create() function use the native_flags variable.
+ This allows us to actually create WRITEABLE MMAPs.
+ [Ed Korthof <ed@apache.org>]
+
+ *) Completely revamp configure so that it preserves the standard make
+ variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
+ the configure additions to EXTRA_* variables. Also, allow the user
+ to specify NOTEST_* values for all of the above, which eliminates the
+ need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
+ of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
+ avoid pointless duplications. Fix the order in which flags are given
+ on the compile and link lines. [Roy Fielding]
+
+ *) Fix DSO code on HP/UX. We have to use == not =, and it makes more
+ sense to actually return errno, so that the return code means
+ something. [Ryan Bloom]
+
+ *) Clean up conditionals in unix DSO code so that we decide based on
+ the dynamic loading implementation, which we noticed at configure
+ time, instead of by operating system.
+ [Wilfredo Sanchez]
+
+ *) Add DSO support for dyld platforms (Darwin/Mac OS and OpenStep).
+ [Wilfredo Sanchez]
+
+ *) Amend the time code to better deal with time zones.
+ [David Reid]
+
+ *) Carefully select an appropriate native type for apr_int64_t and

+ [Justin Erenkrantz, William Rowe]
+
+ *) Make clean, distclean, and extraclean consistently according to the

+
+ *) Initial implementation of of apr_filepath (get/set/parse_root and

+
+ *) Cleaned up implementation of of apr_filepath (get/set/parse_root
+ and merge) for Unix. [Greg Stein, William Rowe]
+
+ *) Fixup the --enable-libtool option. This allows the test directory
+ to compile again. The test directory still doesn't work when
+ APR is configured without libtool. [Ryan Bloom]
+
+ *) If we don't have sigwait() in the system, see if sigsuspend() is
+ available, and use that instead. [Wilfredo Sanchez]
+
+ *) Make libtool optional at configure time. This is done with
+ --disable-libtool. [Ryan Bloom]
+
+ *) Recognize systems where the TCP_NODELAY setting is inherited from
+ the listening socket, and optimize apr_setsockopt(APR_TCP_NODELAY)
+ accordingly. [Jeff Trawick]
+
+ *) Recognize the presence of getnameinfo() on Tru64. [David Reid]
+
+ *) Allow APR to be installed. [Ryan Bloom]
+
+ *) Generate config.nice for easy re-run of configure. [Roy Fielding]
+
+ *) Define preprocessor flags in CPPFLAGS instead of CFLAGS and

+ [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
+
+ *) Add a with-sendfile option, so that people on platforms without a

+
+ *) Introduce apr_get_userid to return a named user's apr_uid_t and

+
+ *) In apr_shm_init(), check the retcode from mm_malloc(). Previously,

+ error scenario is when the lock file lives on a filesystem which
+ doesn't support locking. [Jeff Trawick]
+
+ *) Name protected the autoconf macros defined by APR. Moved the
+ REENTRANCY_FLAGS settings into apr_hints.m4. Inlined the
+ APR_PREPARE_MM_DIR macro because it could only be used once.
+ Removed the unused macros MY_TRY_RUN, MY_TRY_RUN_NATIVE, and
+ AC_USE_FUNCTION. Added some macro comments. [Roy Fielding]
+
+ *) Cope with BSDi installations where the default make has been
+ replaced with GNU make. [Joe Orton <joe@manyfish.co.uk>]
+
+ *) Changed apr/helpers to apr/build to be consistent with other Apache
+ source trees. Added make variables to rules.mk.in that point to the

+ and Makefile.in files to create and use the new scripts. Moved scandoc
+ to scandoc.pl and its default.pl template to scandoc_template.pl.
+ [Roy Fielding]
+
+ *) Updated config.guess and config.sub to GNU libtool 1.3.5 features,
+ with the Apache additions for OS/390 and OS/2 emx. [Roy Fielding]

+ *) Force FreeBSD to compile without threads by default. To enable
+ threads, use --enable-threads on the configure line.
+ [Ryan Bloom]
+
+ *) Purge system password buffer before returning from apr_password_get.
+ No longer abuses bufsize argument on return. [William Rowe]
+
+ *) Moved the prototypes for apr_snprintf and apr_vsnprintf to the
+ apr_strings.h header, from apr_lib.h. This location makes more
+ sense. [Ryan Bloom]
+
+ *) Added the APR_TRY_COMPILE_NO_WARNING configure macro for testing a
+ compile with -Werror as well as the APR_CHECK_ICONV_INBUF macro to
+ test for annoying iconv prototype differences.
+ [Jeff Trawick, Roy Fielding]
+
+ *) Fix a problem with configure on NetBSD. We must include sys/types.h
+ for some platforms. [jun-ichiro hagino <itojun@kame.net>]
+
+ *) Some fixes in the Win32 time support.
+ (IsLeapYear): New macro for quickly figgerin' out if a given year is a
+ leap year. (SystemTimeToAprExpTime): Perform the calculation of
+ tm_yday. Also, negate the sign of the tm_gmtoff field to be
+ consistent with Unix platforms and APR header file comments.
+ [Mike Pilato]
+
+ *) Implement WinNT Unix'ish permissions. [William Rowe]
+
+ *) Corrected an OS2'ism of apr_get_home_directory. OS2 now returns the
+ proper directory, including the user's name.
+
+ *) Removed private os2errno.h and integrated the OS2 network error codes
+ into apr_errno.h for optimized error tests (APR_STATUS_IS_EFOO(rv)).
+ [William Rowe]
+
+ *) Moved inclusion of <os2.h> header from multiple modules into apr.h
+ [William Rowe]
+
+ *) Added apr_compare_users() and apr_compare_groups() for more complex
+ apr_uid_t and apr_gid_t structures. Enabled both .user and .group
+ results from WinNT/2000 stat/getfileinfo, but expect to find that
+ .group is 'None' in most cases. [William Rowe]
+
+ *) Replace configure --with-optim option by using the environment
+ variable OPTIM instead. This is needed because configure options
+ do not support multiple flags separated by spaces. [Roy Fielding]
+
+ *) Eliminate the APR_SIG* aliases for standard signal names,
+ since they serve no useful purpose. [Roy Fielding]
+
+ *) Abstracted apr_get_username and apr_get_groupname for unix and win32.
+ Modified Win32 apr_uid_t and apr_gid_t to use PSIDs, and elimintated
+ the uid_t and gid_t definitions. [William Rowe]
+
+ *) Radically refactored apr_stat/lstat/getfileinfo/dir_read for Win32
+ to assure we are retrieving what we expect to retrieve, and reporting
+ the correct result (APR_SUCCESS or APR_INCOMPLETE). The potential
+ for a bit more optimization still remains. [William Rowe]
+
+ *) While we have the future opportunity to cache the apr_stat'ed file
+ handle for a very fast open (dup handle) on Win32, patched to close
+ that file after a stat always. Needs a new semantic before we leave
+ handles dangling when the user intends to rm. [William Rowe]
+
+ *) Correct Win32 apr_stat/lstat/getfileinfo/dir_read to all zero out
+ the finfo buffer on success (or incomplete success). [William Rowe]
+
+ *) Fix Win32/Unix apr_lstat to throw the .valid bit APR_FINFO_LINK to
+ indicate we attempted to open the link. Only the .filetype APR_LNK
+ reflects if the file found was, in fact, a link. [William Rowe]
+
+ *) Fixed apr_open and apr_rename to function on Win9x.
+ [Mike Pilato <cmpilato@collab.net>]
+
+ *) Add apr_open_stdout. This mirrors apr_open_stderr, except it works
+ on stdout. [Mike Pilato <cmpilato@collab.net>]
+
+ *) Fix bug in file_io/unix/dir.c. There is no such thing as a dirent,
+ it must be a struct dirent.
+ [Kevin Pilch-Bisson <kevin@pilch-bisson.net>]
+
+ *) Fix the configure script so that we can build from a different
+ directory. [Kevin Pilch-Bisson <kevin@pilch-bisson.net>]
+
+ *) Introduce the wanted flag argument to the apr_stat/lstat/getfileinfo
+ family of functions. This change allows the user to determine what
+ platform-specific file information is retrieved, to optimize both
+ portability and performance. [William Rowe]
+
+ *) Fix make depend. [Ryan Bloom]
+
+ *) All dso implementations now register a cleanup to unload the DSO
+ when it is loaded. If the pool is removed, we really do need to
+ remove the DSO. In the past, different platforms behaved differently
+ it this respect. [Ryan Bloom]
+
+ *) Add linkage declarations to the DSO code.
+ [Gregory Nicholls <gnicholls@level8.com>]
+
+ *) Some adjustment of hints.m4 setting flags (used to check if null
+ first) and added some verbosity. [Jim Jagielski]
+
+ *) Specify APR_DECLARE to some of the APR functions. This helps linking
+ on some operating systems. [Gregory Nicholls <gnicholls@level8.com>]
+
+ *) Libtool'ized APR and converted all the makefiles to share rules
+ from helpers/rules.mk. [Greg Stein]
+
+ *) Remove a warning on FreeBSD. FreeBSD defines TCP_NO_PUSH, but we
+ don't actually use it. This causes os_cork to be defined but not
+ used. This patch keeps us from defining os_cork and os_uncork on
+ FreeBSD. [Ryan Bloom]
+
+ *) Keep apr_terminate from seg faulting on terminate. This is
+ happening on systems that do not NULL out locks when they are
+ destroyed. To keep this from happening, we set the locks to
+ NULL after destroying them in apr_terminate, and we have to
+ check for NULL in free_blocks.
+ [Allan Edwards and Gregory Nicholls <gnicholls@level8.com>]
+
+ *) Remove the ability to allocate memory out of a NULL pool.
+ [Ryan Bloom]
+
+ *) Add an APR_GET_POOL macro to get a pool from any APR type that has
+ a pool. This requires that ALL apr types put the pool as the first
+ field in their structure. [Ryan Bloom]
+
+ *) Begin to remove the ability to allocate out of NULL pools. The first
+ problem to solve, is that we need an apr_lock in order to allocate
+ pools, so that we can lock things out when allocating. So, how do we
+ allocate locks without a pool to allocate from? The answer is to create
+ a global_apr_pool, which is a bootstrapping pool. There should NEVER
+ be a sub-pool off this pool, and it is static to an APR file. This is
+ only used to allow us to allocate the locks cleanly, without using the
+ NULL pool hack. [Ryan Bloom]
+
+ *) Fix a logic error in the poll code when implemented using select.
+ [Nick Caruso <ncaruso@gamesville.com>]
+
+ *) FreeBSD does not support sendfile() in combination with threads
+ before version 4.2. We no longer even try to support it.
+ [Ryan Bloom]
+
+ *) On FreeBSD, it is possible for the first call to sendfile to
+ get EAGAIN, but still send some data. This means that we cannot
+ call sendfile and then check for EAGAIN, and then wait and call
+ sendfile again. If we do that, then we are likely to send the
+ first chunk of data twice, once in the first call and once in the
+ second. If we are using a timed write, then we check to make sure
+ we can send data before trying to send it. [Ryan Bloom]
+
+ *) Cleanup to help Apache support programs build cleanly.
+ [Cliff Woolley <cliffwoolley@yahoo.com>]
+
+ *) Cleanup some compiler warnings on Solaris
+ [Dale Ghent <daleg@elemental.org>]
+
+ *) apr_getaddrinfo() can now return multiple addresses for a host
+ via the next field in apr_sockaddr_t. [Jeff Trawick]
+
+ *) Tighten up the check for getaddrinfo(). If it can't figure out
+ the appropriate address family for 127.0.0.1, it fails.
+ Unfortunately, Tru64 fails this test so we won't do IPv6 on
+ Tru64. [Jeff Trawick]
+
+ *) Rename apr_opendir to apr_dir_open. [Ryan Bloom]
+
+ *) apr_snprintf()'s %pI format string now takes apr_sockaddr_t *
+ instead of sockaddr_in *. [Jeff Trawick]
+
+ *) Fix a bug in apr_accept() for Win32 and Unix where the local
+ apr_sockaddr_t in the new connected socket was not initialized
+ properly. This could result in a bad string for apr_get_ipaddr(),
+ among other things. [Jeff Trawick]
+
+ *) Add apr_getnameinfo(), a replacement for apr_get_hostname() which
+ supports IPv6 and will be friendlier for use with eventual
+ SOCK_DGRAM support. apr_get_hostname() is gone. [Jeff Trawick]
+
+
+Changes with APR a9
+
+ *) Removed the iconv implementation from the i18n/unix/iconv branch.
+ This now resides in the apr-iconv repository, and will be ported
+ over time to use native apr types (e.g. apr_dso) for portability.
+
+ *) Only support IPv6 if we have sockaddr_in and a working
+ getaddrinfo(). [Jeff Trawick]
+
+ *) Add apr_parse_addr_port() for parsing the hostname:port portion
+ of URLs and similar strings. [Jeff Trawick]
+
+ *) Add Win32 MMAP support [William Rowe]
+
+ *) Allow the APR programmer to specify if the MMAP is read-only or
+ write-able.
+ [Ryan Bloom and Will Rowe]
+
+ *) Check more carefully for getaddrinfo(). Accept those that
+ require <netdb.h> to be included (e.g., Tru64). Reject those that
+ fail a very basic operational test (e.g., AIX). [Jeff Trawick]
+
+ *) Add apr_make_os_sock() for constructing a fully-capable APR
+ socket. [Jeff Trawick]
+
+ *) Make APR's shared memory routines always allocate enough memory
+ for the requested segment, the MM internal types, and the APR
+ internal types.
+ [Ryan Bloom]
+
+ *) Add APR_SIZE_T_FMT. Get the other APR_xx_T_FMT variables
+ defined properly on AIX. [Jeff Trawick]
+
+ *) network API changes: get rid of apr_get_socket_inaddr(),
+ apr_get_remote_name(), and apr_get_local_name() [Jeff Trawick]
+
+ *) Add a step at configure time to create a file at the top-level,
+ apr.exports, which lists every function exported by APR. The
+ file is generated by a script in helpers, that reads each header
+ file.
+ [Ryan Bloom]
+
+ *) Lock config changes: Detect SysV sem capability by the presence of
+ sempaphore functions, not by the presence of union semun. New
+ config variable apr_lock_method can override autodetection of the
+ apr_lock implementation method. For now, hints.m4 uses it to select
+ SysV semaphores for OS/390. New config variable
+ apr_process_lock_is_global specifies that the selected inter-process
+ lock method is sufficient for APR_LOCKALL (i.e., it blocks all
+ threads and processes). For now, hints.m4 turns on this flag for
+ OS/390. [Jeff Trawick]
+
+ *) Get APR_OFF_T_FMT defined properly on Solaris Sparc.
+ [Jeff Trawick]
+
+
+Changes with APR a8
+
+ *) Change the name of the sa_len field in apr_sockaddr_t to salen.
+ Some platforms have a macro named sa_len.
+ [Tony Finch]
+
+ *) apr_set_port(), apr_get_port(), apr_set_ipaddr(), and apr_get_ipaddr()
+ now take apr_sockaddr_t as a parameter instead of apr_socket_t +
+ apr_interface_e. This will allow the same routines to be used with
+ datagram APIs to be added later. Note that code which calls
+ apr_set_ipaddr() should probably be changed to call apr_getaddrinfo()
+ for protocol independence. [Jeff Trawick]
+
+ *) apr_create_tcp_socket() has been removed. Use apr_create_socket()
+ instead. [Jeff Trawick]
+
+ *) Source was moved from the apache-2.0 repository. For all CHANGES
+ prior to this time, please see the apache-2.0 repository
