Changes for APR 1.7.5

*) Unix: Implement apr_shm_perms_set() for the "POSIX shm_open()"
     and "classic mmap" shared memory implementations.  [Joe Orton,
     Ruediger Pluem]

*) Fix missing ';' for XML/HTML hex entities from apr_escape_entity().
     [Yann Ylavic]

*) Fix crash in apr_pool_create() with --enable-pool-debug=all|owner.
     [Yann Ylavic]

*) Improve platform detection by updating config.guess and config.sub.
     [Rainer Jung]

*) CMake: Add support for CMAKE_WARNING_AS_ERROR. [Ivan Zhakov]

*) CMake: Enable support for MSVC runtime library selection by abstraction.
     [Ivan Zhakov]

*) CMake: Export installed targets (libapr-1, apr-1, libaprapp-1, aprapp-1)
     to apr:: namespace. [Ivan Zhakov]

Changes for APR 1.7.4

*) Fix a regression where writing to a file opened with both APR_FOPEN_APPEND
     and APR_FOPEN_BUFFERED did not properly append the data on Windows.
     (This regression was introduced in APR 1.7.3)  [Evgeny Kotkov]

Changes for APR 1.7.3

*) apr-1-config: Fix crosscompiling detection in apr-1-config. PR 66510
     [Ruediger Pluem]

*) configure: Add --enable-sysv-shm to use SysV shared memory (shmget) if
     available. [Ruediger Pluem]

*) apr_socket_sendfile: Use WSAIoctl() to get TransmitFile function
     pointer on Windows. [Ivan Zhakov]

*) apr_dir_read: Do not request short file names on Windows 7
     and later. [Ivan Zhakov]

*) apr_file_gets: Optimize for buffered files on Windows.
     [Evgeny Kotkov]

*) Fix a deadlock when writing to locked files opened with APR_FOPEN_APPEND
     on Windows. PR 50058. [Evgeny Kotkov]

*) Don't seek to the end when opening files with APR_FOPEN_APPEND on Windows.
     [Evgeny Kotkov]

*) apr_file_write: Optimize large writes to buffered files on Windows.
     [Evgeny Kotkov]

*) apr_file_read: Optimize large reads from buffered files on Windows.
     [Evgeny Kotkov]

Changes for APR 1.7.2

*) Correct a packaging issue in 1.7.1. The contents of the release were
     correct, but the top level directory was misnamed.

Changes for APR 1.7.1

*) SECURITY: CVE-2022-24963 (cve.mitre.org)
     Integer Overflow or Wraparound vulnerability in apr_encode functions of 
     Apache Portable Runtime (APR) allows an attacker to write beyond bounds 
     of a buffer.

*) SECURITY: CVE-2022-28331 (cve.mitre.org)
     On Windows, Apache Portable Runtime 1.7.0 and earlier may write beyond 
     the end of a stack based buffer in apr_socket_sendv(). This is a result 
     of integer overflow.

*) SECURITY: CVE-2021-35940 (cve.mitre.org)
     Restore fix for out-of-bounds array dereference in apr_time_exp*() functions.
     (This issue was addressed as CVE-2017-12613 in APR 1.6.3 and
     later 1.6.x releases, but was missing in 1.7.0.)  [Stefan Sperling]

*) configure: Fix various build issues for compilers enforcing
     strict C99 compliance.  PR 66396, 66408, 66426.
     [Florian Weimer <fweimer redhat.com>, Sam James <sam gentoo.org>]

*) apr_atomic_read64(): Fix non-atomic read on 32-bit Windows [Ivan Zhakov]

*) configure: Prefer posix name-based shared memory over SysV IPC.
     [Jim Jagielski]

*) configure: Add --disable-sctp argument to forcibly disable SCTP
     support, or --enable-sctp which fails if SCTP support is not
     detected.  [Lubos Uhliarik <luhliari redhat.com>, Joe Orton]

*) Fix handle leak in the Win32 apr_uid_current implementation.
     PR 61165. [Ivan Zhakov]

*) Add error handling for lseek() failures in apr_file_write() and
     apr_file_writev().  [Joe Orton]

*) Don't silently set APR_FOPEN_NOCLEANUP for apr_file_mktemp() created file
     to avoid a fd and inode leak when/if later passed to apr_file_setaside().
     [Yann Ylavic]

*) APR's configure script uses AC_TRY_RUN to detect whether the return type
     of strerror_r is int. When cross-compiling this defaults to no.

This commit adds an AC_CACHE_CHECK so users who cross-compile APR may
     influence the outcome with a configure variable. [Sebastian Kemper
     <sebastian_ml gmx net>]

*) Add a cache check with which users who cross-compile APR
     can influence the outcome of the /dev/zero test by setting the variable
     ac_cv_mmap__dev_zero=yes [Sebastian Kemper <sebastian_ml gmx net>]

*) Trick autoconf into printing the correct default prefix in the help.
     [Stefan Fritsch]

*) Don't try to use PROC_PTHREAD by default when cross compiling.
     [Yann Ylavic]

*) Add the ability to cross compile APR. [Graham Leggett]

*) While cross-compiling, the tools/gen_test_char could not
     be executed at build time, use AX_PROG_CC_FOR_BUILD to
     build native tools/gen_test_char

Support explicit libtool by variable assigning before buildcheck.sh,
     it is helpful for cross-compiling (such as libtool=aarch64-linux-libtool)
     [Hongxu Jia <hongxu.jia windriver.com>]

*) Avoid an overflow on 32 bit platforms. [René Hjortskov Nielsen
     <r... hjortskov.dk>]

*) Use AC_CHECK_SIZEOF, so as to support cross compiling. PR 56053.
     [Mike Frysinger <vapier gentoo.org>]

*) Add --tag=CC to libtool invocations. PR 62640. [Michael Osipov]

*) apr_pools: Fix pool debugging output so that creation events are
     always emitted before allocation events and subpool destruction
     events are emitted on pool clear/destroy for proper accounting.
     [Brane Čibej]

*) apr_socket_listen: Allow larger listen backlog values on Windows 8+.
     [Evgeny Kotkov <evgeny.kotkov visualsvn.com>]

*) Fixed: apr_get_oslevel() was returning APR_WIN_XP on Windows 10

*) Fix attempt to free invalid memory on exit when apr_app is used
     on Windows. [Ivan Zhakov]

*) Fix double free on exit when apr_app is used on Windows. [Ivan Zhakov]

*) Fix a regression in apr_stat() for root path on Windows. [Ivan Zhakov]

Changes for APR 1.7.0

*) apr_dir_read: [Unix] Dropped the preference of the dirread_r() flavor
     for dirread(), because the former is both deprecated and unneeded.
     [Yann Ylavic, William Rowe]

*) apr_file_info: [Win32 only] Treat only "name surrogate" reparse points
     as symlinks, and not other reparse tag types. PR47630
     [Oleg Liatte <olegliatte gmail.com>]

*) Test %ld vs. %lld to avoid compiler emits using APR_OFF_T_FMT, in the
     case of apparently equivilant long and long long types. [William Rowe]

*) Recognize APPLE predefined macros as equivilant to DARWIN. [Jim Jagielski]

*) Signals: Allow handling of SIGUSR2 in apr_signal_thread. [Yann Ylavic]

*) Atomics: Support for 64bit ints. [Jim Jagielski]

*) Add the apr_encode_* API that implements RFC4648 and RFC7515
     compliant BASE64, BASE64URL, BASE32, BASE32HEX and BASE16
     encode/decode functions. [Graham Leggett]

*) rand: Use arc4random_buf() on BSD platforms and getrandom() on Linux,
     when available. [Christian Weisgerber <naddy openbsd.org, Yann Ylavic]

*) Add apr_sockaddr_zone_set, apr_sockaddr_zone_set to set and retrieve
     the zone for link-local IPv6 addresses.  [Joe Orton]

*) apr_sockaddr_equal: Compare link-local IPv6 addresses with different
     zones as not equal.  [Joe Orton]

*) apr_sockaddr_ip_getbuf, apr_sockaddr_ip_get: Append "%zone" for
     IPv6 link-local addresses.  [Joe Orton]

*) Locks: add a --disable-timedlocks config option in case users
     encounter more platforms where it fails [Nick Kew].

*) apr_allocator, apr_pools: Add apr_allocator_page_size() and
     apr_allocator_min_order_set() to respectively get the (system's) page size
     in use and set the minimum allocation size for an allocator (expressed in
     2^order pages).  [Yann Ylavic]

*) locks: provide portable implementations of timedlock()s for
     posix-sems, sysv-sems and pthreads for those platforms that
     lack native versions (eg: OSX/macOS). [Jim Jagielski]

*) locks: Introduce apr_{thread,proc,global}_mutex_timedlock().
     [Yann Ylavic]
