Changes for APR 1.6.4

  *) configure: Fix detection of <net/if.h> on OpenBSD.
     PR 61976. [David Carlier <devnexen gmail.com>, Yann Ylavic]

  *) Fix apr_parse_addr_port() regression in scope_id parsing introduced
     in 1.6.3.  [Rainer Jung]

  *) Fix Win32 file buffer locking behavior for single threaded file streams.
     [Evgeny Kotkov, Mladen Turk, Jean-Frederic Clere]

  *) Numerous corrections to APR poll behavior. [Yann Ylavic]

Changes for APR 1.6.3

  *) apr_file_trunc: Truncating a buffered file could add unexpected
     data after the truncate position. PR 51017.
     [Evgeny Kotkov <evgeny.kotkov visualsvn.com>]

  *) apr_file_trunc: Fix an issue where reading from a buffered file
     after truncate could return stale data from the buffer.
     [Evgeny Kotkov <evgeny.kotkov visualsvn.com>]

  *) apr_ipsubnet_create() now fails for an empty input string.
     [Joe Orton]

Changes for APR 1.6.2

  *) Corrected non-Unix builds for APR_LOCK_DEFAULT.

Changes for APR 1.6.1

  *) Defer timed locks API for later 1.7 release [Nick Kew, William Rowe]

  *) Export build files find_apr.m4 and apr_common.m4 [Jacob Champion]

Changes for APR 1.6.0

  *) apr_allocator: Provide apr_allocator_align() to get the true size that
     would be allocated for the given size (including the header and
     alignment).  [Yann Ylavic]

  *) apr_os_proc_mutex_put_ex: Allow to specify whether the OS native
     mutex should or not be cleaned up (destroyed) with the constructed
     APR mutex (given pool), and default to not for the simple _put()
     function.  [Yann Ylavic]

  *) apr_proc/global_mutex: Fix API regarding the native OS mutexes
     accessors from/to available APR mechanisms, adding the new functions
     apr_os_proc_mutex_get_ex() and apr_os_proc_mutex_set_ex() which give
     control to the user over the selected mechanisms, including the missing
     POSIX semaphores (sem_t) on platforms supporting them.
     [Yann Ylavic]

  *) apr_proc_mutex-pthread: Refcount shared mutexes usage to avoid
     destruction while still is use by some process(es).  PR 49504.
     [Yann Ylavic]

  *) apr_file_io: Add apr_file_pipe_create_pools() allowing a pair of
     pipes to be created, each in a different pool. [Graham Leggett]

  *) Add apr_pollcb_wakeup(), with similar behavior to
     apr_pollset_wakeup(). Add apr_pollcb_method_name(), with similar 
     behavior to apr_pollset_method_name().
     [Neil Conway <nrc cs berkeley edu>, Jeff Trawick]

  *) apr_table_overlap: Add APR_OVERLAP_TABLES_ADD to merge and set when
     overlapping tables. [Graham Leggett]

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

  *) Introduce the apr_cstr_fn() family of functions, derived from
     the svn_cstring_ functions of the Subversion project.

  *) Add APR_SO_FREEBIND option for apr_socket_opt_set.  PR 58725.
     [Ashley GC, Jan Kaluza, Joe Orton]

  *) apr_filepath_merge: Fix truename length calculation on Windows
     in cases where the "short" name variant is actually longer than
     the "long" or "true" name. See: testnames.c:merge_shortname().
     [Bert Huijben <rhuijben a.o>]

  *) apr_atomic: Fix errors when building on Visual Studio 2013 while
     maintaining the ability to build on Visual Studio 6 with Windows
     Server 2003 R2 SDK. PR 57191. [Gregg Smith]

  *) apr_skiplist: Add apr_skiplist_addne*() family to preserve existing
     values (no duplicate), add apr_skiplist_size(), apr_skiplist_height()
     and apr_skiplist_preheight() to get the corresponding current values,
     and apr_skiplist_set_preheight() to modify it. [ Yann Ylavic ]

  *) Add new --enable-allocator-guard-pages which is like allocator-uses-mmap,
     but will also add inaccessible guard pages before and after each memnode.
     This will result in higher ressource usage but allow to find/protect
     against certain buffer overflow/overread bugs. Under Linux, it may be
     necessary to increase /proc/sys/vm/max_map_count . [Stefan Fritsch]

  *) apr_skiplist: Add apr_skiplist_add() to support multiple values.

  *) Add new --enable-pool-concurrency-check configure option to detect
     thread-unsafe concurrent accesses to pools. Runtime costs should be
     relatively low. [Stefan Fritsch]

  *) Add support code to teach valgrind about APR pools and allocators.
     [Stefan Fritsch]

  *) Add apr_sockaddr_info_copy(), for making a deep copy of an
     apr_sockaddr_t into a specified pool.  [Yann Ylavic
     <ylavic.dev gmail.com>]

  *) Added Unix domain socket support.
     [Mladen Turk]

  *) Add apr_shm_delete() to compliment apr_shm_remove().
     [Jim Jagielski]

  *) Intruduce APR_PERMS_SET macros for setting the owner/group on
     objects. Currently only implemented for shm, proc and global
     mutexes on posix platforms.
     [Mladen Turk]

  *) Add apr_escape_ldap() and apr_pescape_ldap(), escaping characters
     as described by RFC4514 and RFC4515 respectively. [Graham Leggett]
