Changes for APR 1.2.7 *) Netware - add missing apu_version.c parsing for apu_version_string() to the Netware specific builds. Unix platforms supporte this API since 0.9.1. [Brad Nicholes] *) Fix a regression in the updated win32 apr_file_read with timeouts since 1.2.6 which would fail to return the bytes read in specific 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) for correct compilation. Resolves various apr_os_uuid issues on multiple environments. [William Rowe] *) Prevent detection of robust mutex support with glibc 2.4, fixing APR_LOCK_PROC_PTHREAD locks. PR 38442. [Joe Orton] *) Correct bug in kqueue backend for apr_pollset where we would erroneously indicate that a socket was readable or writeable. [Garrett Rooney] *) Make the filePtr in apr_file_t an apr_off_t on Unix, to avoid issues truncating offsets down to 32 bits on large file systems. [Garrett Rooney] *) Fix seeks with files opened in xthread mode for append on win32. [M Joonas Pihlaja <jpihlaja cc.helsinki.fi>, Garrett Rooney] *) Keep testpipe.c from hanging on win32. [Garrett Rooney] *) Cause apr_file_write_full on win32 to consider the timeout value set by apr_file_pipe_timeout_set. PR 30182 [<eholyat olf.com>] *) Fix assertion from double close of a handle with a rwlock on win32. [Evgueni Brevnov <evgueni.brevnov gmail.com>] *) Fix EOF handling for unbuffered reads on win32. [Konstantin Sharenkov <Konstantin.Sharenkov enterra-inc.com>] *) Documented that apr_stat and apr_dir_read can return APR_INCOMPLETE, and how to determine which parts of the resulting apr_finfo_t can be used in such a case. [Garrett Rooney] *) Fix passing "" as an argument to the program started by apr_proc_create on Win32. [Philip Martin <philip codematters.co.uk> *) Bugfix for apr_pollset_poll() on systems that implement pollsets using select(2): properly compute the number of signalled desciptors 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 pending writes for a buffered file. [Joe Orton] Changes for APR 1.2.2 *) Fix crash in apr_dir_make_recursive() for relative path when the working directory has been deleted. [Joe Orton] *) Win32: fix apr_proc_mutex_trylock() to handle WAIT_TIMEOUT, returning APR_EBUSY. [Ronen Mizrahi <ronen@tversity.com>] *) Fix apr_socket_opt_set() issue where TCP_NODELAY would be 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] *) Fix apr_file_gets() and apr_file_read() to catch write failures when flushing pending writes for a buffered file. [Joe Orton] *) Fix apr_file_write() infinite loop on write failure for buffered files. [Erik Huelsmann <ehuels gmail.com>] *) Fix error handling where apr_uid_* and apr_gid_* could return APR_SUCCESS in failure cases. PR 34053 continued. [Joe Orton] Changes for APR 1.2.1 *) Refactor Win32 condition variables code to address bugs 27654, 34336. [Henry Jen <henryjen ztune.net>, E Holyat <eholyat yahoo.com>] Changes for APR 1.2.0 *) If getpwuid_r or getgrgid_r set their results to NULL, it is an error. 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 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] *) Fix Pollset corruption on Solaris 10. [Paul Querna] *) Add %pt support to apr_snprintf() for printing an apr_os_thread_t in hex format. [Jeff Trawick] *) Support APR_SO_SNDBUF and APR_SO_RCVBUF on Windows. PR 32177. [Sim <sgobbi datamanagement.it>, Jeff Trawick] *) Fix apr_table_overlap()'s handling of tables allocated from different pools.

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] *) Rewrite apr_file_printf to handle arbitrary length strings. PR 28029. [Chris Knight <Christopher.D.Knight nasa.gov>, Garrett Rooney <rooneg electricjellyfish.net>] Changes for APR 1.0.2 *) [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.

[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.

[Philip Martin <philip codematters.co.uk>] *) Add APR_LARGEFILE flag to allow opening files with the O_LARGEFILE flag; not recommended for general use, see include/apr_file_io.h. [Joe Orton] *) Various build fixes: thread_rwlock.c on some Solaris platforms (PR 22990); filestat.c on ReliantUnix (PR 22990); config.status on IRIX (PR 19251). [Various] *) Use NI_NAMEREQD instead of NI_NUMERICHOST in APR_CHECK_GETNAMEINFO_IPV4_MAPPED. PR 24469. [Justin Erenkrantz] *) Ensure that apr_sockaddr_info_get() does not return anything other than AF_INET and AF_INET6 addresses. [Joe Orton] *) Clarify that apr_dir_read() does not guarantee order of returned entries as previously claimed. [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] *) 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 *) win32: fix apr_file_dup() and apr_file_dup2() to dup the ungetchar member [Stas Bekman] *) Preserve leading '../' segments as when merging to an empty and unrooted path - fixes a bug observed in SVN with Win32/Netware/OS2. [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, Justin Erenkrantz] *) Add apr_temp_dir_get() for getting the most suitable temp directory [Mike Pilato <cmpilato collab.net>, Thom May] *) Modify apr_sockaddr_info_get to call the resolver when we do not have a hostname. Also, fix bugs in the getaddrinfo() implementation. [Colm MacCárthaigh <colm stdlib.net>, Justin Erenkrantz] *) Change the behavior of unix process 'trylock's to return APR_ENOTIMPL instead of segfaulting, consistent with the other lock implementations. [William Rowe] *) Fix a subtle race where the ownership of a unix nested thread lock could be corrupted when the prior owner released the lock with another thread waiting on the same lock. [William Rowe] *) apr_socket_data_set(): allow the same key to be used for multiple sockets in the same pool. [Jeff Trawick] *) Add new table function apr_table_compress() and replace red-black trees with mergesort in apr_table_overlap() [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] *) Add parameter to APR_SUBDIR_CONFIG to drop options passed to configure before the subdir's configure is invoked. [Jeff Trawick, Justin Erenkrantz] *) Implement APR_SO_RCVBUF socket option on Unix. [Adam Sussman <myddryn vishnu.vidya.com>] *) Don't add the math library (-lm) if the modf() function is already available via libc. [Roy Fielding] *) Solaris cc: Don't use the -mt option for threaded builds. That is for non-Posix threading, and the use of it prevented us from linking with -lpthread, which in turn caused weird problems for APR applications. [Kristofer Spinka <kspinka style.net>] *) OS/2: apr_stat() fixes - When a character device is stat'ed, fill in finfo.name if it was asked for. Return APR_INCOMPLETE when appropriate. Addresses httpd incident [CAN-2003-0134]. [Brian Havard] Changes with APR 0.9.3 *) Don't enable posixsem, at build time, on systems where sem_t * won't "fit" into an int (sizeof-wise). Also, better error handling when we fail to create a posixsem. PR 17186 [Scott Herod <sherod pillardata.com>, Jim Jagielski] *) Default hpux 10.x to disable threading, since if it exists at all the pthread implementation should not be trusted, while hpux 10 had its own threads implementation that is no longer supported. PR 9457 [William Rowe] *) Fix error in apr-config when symlinks are involved. [Garrett Rooney <rooneg electricjellyfish.net>] Changes with APR 0.9.2 *) Numerous bug fixes for file and socket inheritence by child processes on Unix, correcting bugs that affected the correct behavior of apr_[file|socket]_inherit_[un]set() API. [Bjoern A. Zeeb <bz zabbadoz.net>, William Rowe, Joe Orton] *) Define APR_UINT64_T_FMT and APR_UINT64_T_FMT_LEN. Define APR_INT64_T_FMT_LEN on Windows and Netware. [Branko Cibej] *) Correct apr_file_gets() on OS2 and Win32 so that '\r's are no longer eaten, and apr_file_gets() -> apr_file_puts() moves the contents uncorrupted. [William Rowe] *) Alter Win32's handling of the apr_proc_t hproc member, so that we close that system handle wherever an apr function would invoke the final waitpid() against a zombie process on Unix. [William Rowe] *) APR_MAX_SECONDS_TO_LINGER and APR_FNM_* #defines replace their old undecorated names (missing APR_ prefix). The old names will disappear with APR 1.0.0. [Craig Rodrigues <rodrigc@attbi.com>, William Rowe] *) When generating a semaphore name for posixsem locking, try to be a little more robust (and unique). [Jim Jagielski] *) Add functions apr_env_get, apr_env_set and apr_env_delete for manipulating the environment. [Branko Cibej] *) Fix APR_LAYOUT to work with layout files with no preceding blank lines and emit errors when layout is not found. PR 15679. [Justin Erenkrantz] *) Add functions apr_filepath_list_split and apr_filepath_list_merge for managing search paths. [Branko Cibej] *) Introduce Release mode debugging symbols for Win32 builds of apr. All library builds gain /Zi for debug symbols (which are discarded at link time if some flavor of the /debug flag isn't passed to link) and .dll builds gain .pdb symbols. [Allen Edwards, William Rowe] *) Add two new proc attributes to improve diagnostics for apr_proc_create() failures on platforms where fork()+exec() is used. See the doc for apr_procattr_child_errfn_set() and apr_procattr_error_check_set(). [Jeff Trawick] *) Rename rules.mk to apr_rules.mk and make apr_rules.mk be installed. [Thom May] *) Fix a bug in apr_proc_create() that could cause a new child process to run the parent's code if setrlimit() fails. [Jeff Trawick] *) Disable apr_socket_sendfile() on 64-bit AIX to avoid an apparent system problem. PR 11408. [Jeff Trawick] *) Add --includedir flag to apr-config. [Justin Erenkrantz] *) Only include sys/syslimits.h if we don't have limits.h [Craig Rodrigues <rodrigc@attbi.com>, Garrett Rooney <rooneg@electricjellyfish.net>, Thom May] *) Allow apr-config to work in symlinked install directories when 'realpath' is available. [Justin Erenkrantz] *) Namespace protect the header files in include/arch [Thom May] *) Add function apr_filepath_encoding and associated constants. [Branko Cibej] *) Allow apr_hash to have greater than int number of elements. [Justin Erenkrantz] *) Allow generation of dependencies by non-GCC compilers. [Justin Erenkrantz] *) Prevent obscenely large values of precision in apr_vformatter from clobbering a buffer. [Sander Striker, Jim Jagielski] *) limit the renames performed in apr_rename.pl to the most recent renames. [Thom May] *) Changed apr_mmap_dup() and friends so that there's no longer any is_owner concept on the mmaped region, but rather something more along the lines of a reference count.

[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 some new logic that is going into HTTPD. I have left the join logic 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 (default="--silent") and introduce LT_LDFLAGS. [Roy Fielding] *) Add memory code kindly donated to APR by Elrond <elrond@samba-tng.org> Luke Kenneth Casson Leighton <lkcl@samba-tng.org> Sander Striker <striker@samba-tng.org> [David Reid] *) Fix a problem with the FreeBSD flavor of apr_sendfile() where we could return APR_EAGAIN+bytes_sent. [Jeff Trawick] *) Fix a problem on unixware where clearing h_errno wouldn't work. 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 define its format as APR_INT64_T_FMT and literal using APR_INT64_C(). [Justin Erenkrantz, William Rowe] *) Make clean, distclean, and extraclean consistently according to the Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>] *) Initial implementation of of apr_filepath (get/set/parse_root and merge) for Windows. [William Rowe] *) 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 bring some sanity to the compiler command-lines. [Roy Fielding] *) Use the dso/aix subdirectory for older versions of AIX and fix a number of bugs in the dso code in that directory. [Victor Orlikowski] *) Allow libtool 1.3b to be used. [Victor Orlikowski] *) Misc. Win32 fixes: Set the pool pointer in apr_sockaddr_t structures created with the apr_socket_t to prevent segfault in certain apps. Flush unwritten buffered data when the file is closed. [Jeff Trawick] *) Win32: Get APR to compile with MSVC 5.0 (a.k.a. VC97). PR #7489 [Jeff Trawick] *) First draft implementation of apr_filepath (get/set/parse_root and merge) for Unix. [William Rowe] *) Add apr_ipsubnet_create() and apr_ipsubnet_test() for testing whether or not an address is within a subnet. [Jeff Trawick] *) Add apr_sendto and apr_recvfrom for Unix. Start of adding UDP support. [David Reid] *) Add a method to get the password from the system for a given user. [John Barbee <jbarbee@covalent.net>] *) Change the include path order, so that we look for included files in the APR paths first, and the system paths second. [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>] *) Add a with-sendfile option, so that people on platforms without a sendfile implementation for APR can easily disable it from the configure line. [Ryan Bloom] *) Change the check for netinet/tcp.h to work around an issue with that header file on IRIX 6.5 which prevented it from being detected. PR #6459 [Jeff Trawick] *) Introduce apr_get_userid to return a named user's apr_uid_t and apr_gid_t across platforms [Cliff Woolley, William Rowe] *) In apr_shm_init(), check the retcode from mm_malloc(). Previously, we segfaulted here if mm_malloc() failed to get a lock. An example 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 builders directory and its scripts. Updated buildconf, configure.in, 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] *) Moved hints.m4, apr_common.m4, and helpers/apr-conf.m4 into the new build directory as apr_hints.m4, apr_common.m4, apr_network.m4, and apr_threads.m4. [Roy Fielding] *) Get apr_sendfile() working on HP-UX. This gets APR to build on HP-UX without having to turn off APR_HAS_SENDFILE. [Jeff Trawick] *) 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
