+ OSSP sa - Socket Abstraction
+
+ CHANGELOG
+
+ This is a list of all changes to OSSP sa.
+ For a more brief summary please have a look at the NEWS file.
+
+ Changes between 1.2.4 and 1.2.5 (29-Jan-2005 to 02-Oct-2005)
+
+ o Added pkg-config(1) specification sa.pc
+ [Ralf S. Engelschall <rse@engelschall.com>]
+
+ o Upgrade build environment to GNU libtool 1.5.20 and
+ GNU shtool 2.0.3
+ [Ralf S. Engelschall <rse@engelschall.com>]
+
+ o Follow FlexeLint suggestions and "constify" some API
+ function parameters.
+ [Ralf S. Engelschall <rse@engelschall.com>]
+
+ Changes between 1.2.3 and 1.2.4 (24-Jan-2005 to 29-Jan-2005)
+
+ o Fix timeout handling in various functions by fixing the internal
+ select(2) usage: the timeout structure is (standard compliantly)
+ modified in place on some platforms (like Linux), so its values
+ have to be preserved before calls to select(2)).
+ [Robert Wood <Robert.Wood@smdc.army.mil>]
+
+ Changes between 1.2.2 and 1.2.3 (26-Jun-2004 to 24-Jan-2005)
+
+ o Adjusted all copyright messages for new year 2005.
+ [Ralf S. Engelschall]
+
+ o Do not pass NULL directly to variadic functions because NULL
+ is not guarrantied to be a pointer.
+ [Ralf S. Engelschall <rse@engelschall.com>]
+
+ o Added SA_SYSCALL_GETHOSTBYNAME for supporting the overloading
+ of gethostbyname(2) system calls.
+ [Ralf S. Engelschall <rse@engelschall.com>]
+
+ o Upgrade build environment to GNU libtool 1.5.10
+ and GNU shtool 2.0.1
+ [Ralf S. Engelschall <rse@engelschall.com>]
+
+ Changes between 1.2.1 and 1.2.2 (11-Jun-2004 to 26-Jun-2004)
+
+ o Allow negative values for SA_OPTION_LINGER to cover the
+ special case of l_onoff=1/l_linger=0 where a TCP RST
+ based connection termination is performed on close(2).
+ [Alexandre Balaban <abalaban@free.fr>]
+
+ o Provide Autoconf check (AC_CHECK_VA_COPY) for va_copy(d,s) macro
+ and fallback implementations and now that we can be sure that
+ va_copy() exists for us, use it in var_formatv() and ts.c instead
+ of the direct assignments (which are not sufficiently portable).
+ [Ralf S. Engelschall <rse@engelschall.com>]
+
+ o Remove "#undef socklen_t" from sa.h because the socklen_t
+ fallback is a "typedef" since a longer time.
+ [Ralf S. Engelschall <rse@engelschall.com>]
+
+ Changes between 1.2.0 and 1.2.1 (02-Apr-2003 to 11-Jun-2004)
+
+ o Fix timeout implementation related to SO_RCVTIMEO/SO_SNDTIMEO.
+ [Ralf S. Engelschall <rse@engelschall.com>,
+ Thomas Lotterer <thomas@lotterer.net>]
+
+ o Upgrade build environment to GNU libtool 1.5.6
+ [Ralf S. Engelschall <rse@engelschall.com>]
+
+ Changes between 1.1.0 and 1.2.0 (10-Nov-2003 to 02-Apr-2004)
+
+ o In sa_connect() also select(2) on the socket if EINTR was
+ returned similar to what is done already for EINPROGRESS, because
+ one is not allowed to re-start connect(2) according to STEVENS
+ (Unix Network Programming, volume 1, section 5.9) but instead have
+ to perform the same post-processing under EINTR (under both timeout
+ and non-timeout situations) what we already did for EINPROGRESS (in
+ timeout-aware situation).
+ [Ralf S. Engelschall]
+
+ o Adjusted all copyright messages for new year 2004.
+ [Ralf S. Engelschall]
+
+ o Restart accept(2) after interrupted system call.
+ OSSP lmtp2nntp daemon failed to accept a connection after a signal
+ handler was run on Solaris which caused the system call to be
+ interrupted. Issue was found and reported by Amos Gouaux.
+ [Thomas Lotterer <thl@dev.de.cw.net>]
+
+ o Add SA_CHECK_SOCKOPT autoconf check to detect setsockopt failing
+ under run-time on Solaris 2.6,8,9,10 and Debian 2.2 because
+ SO_RCVTIMEO|SO_SNDTIMEO are defined but not implemented.
+ Issue was found and reported by Amos Gouaux.
+ [Thomas Lotterer <thl@dev.de.cw.net>, Amos Gouaux <amos@utdallas.edu>]
+
+ o Upgrade and unify build environment devtool and devtool.func.
+ Change devtool.conf to require current versions of
+ shtool, libtool and autoconf; correct spelling
+ [Thomas Lotterer <thl@dev.de.cw.net>]
+
+ Changes between 1.0.5 and 1.1.0 (31-Jan-2003 to 10-Nov-2003)
+
+ o Upgrade build environment to GNU autoconf 2.58.
+ [Ralf S. Engelschall <rse@engelschall.com>]
+
+ o Upgrade build environment to GNU libtool 1.5.
+ [Ralf S. Engelschall <rse@engelschall.com>]
+
+ o Fix memory leak in test suite (sa_test.c).
+ [Ralf S. Engelschall <rse@engelschall.com>]
+
+ o Added internal address resolving support via the new IEEE Std
+ 1003.1g-2000 ("POSIX.1") getaddrinfo(3) API. This especially
+ provides more portable IPv6 address resolving.
+ [Ralf S. Engelschall <rse@engelschall.com>]
+
+ Changes between 1.0.4 and 1.0.5 (28-Jan-2003 to 31-Jan-2003)
+
+ o Fixed test suite library (ts.c): the ts_suite_free()
+ function performed an illegal iteration for freeing elements (they
+ were freed but still references for traversing to next element).
+ This is now solved by a look-ahead traversion.
+ [Ralf S. Engelschall, Brian T. Egleston <brian@egleston.com>]
+
+ o Fixed test suite (sa_test.c): an sa_addr_t was destroyed
+ too early and this way crashed the test suite.
+ [Brian T. Egleston <brian@egleston.com>]
+
+ Changes between 1.0.3 and 1.0.4 (06-Jan-2003 to 28-Jan-2003)
+
+ o Fixed embedding support: mappings for symbols sa_sendf and sa_id
+ were missing.
+ [Thomas Lotterer <thl@dev.de.cw.net>]
+
+ Changes between 1.0.2 and 1.0.3 (04-Dec-2002 to 06-Jan-2003)
+
+ o Adjusted all copyright messages for new year 2003.
+ [Ralf S. Engelschall]
+
+ o Fixed generated owner in distribution tarball.
+ [Ralf S. Engelschall]
+
+ o Fixed two compile-time warnings in sa_test.c.
+ [Ralf S. Engelschall]
+
+ Changes between 1.0.1 and 1.0.2 (07-Nov-2002 to 04-Dec-2002)
+
+ o Fixed a few bugs and lots of internal type inconsistencies,
+ all found by splint(1).
+ [Ralf S. Engelschall]
+
+ o Upgraded build environment to GNU autoconf 2.57.
+ [Ralf S. Engelschall]
+
+ Changes between 1.0.0 and 1.0.1 (01-Nov-2002 to 07-Nov-2002)
+
+ o Make sure that "va_list" variables are not compared against NULL
+ because this is not possible on all platforms.
+ [Ralf S. Engelschall]
+
+ o Ported to brain-dead OpenUNIX where shutdown(3)'s SHUT_XX values
+ are not easily available and where variables named sa_len conflict
+ with structure fields in vendor headers.
+ [Ralf S. Engelschall]
+
+ o Fixed two compile-time warnings.
+ [Alvaro Lopez Ortega <alvaro@alobbs.com>]
+
+ o Upgraded build environment to GNU shtool 1.6.2
+ [Ralf S. Engelschall]
+
+ Changes between 0.9.3 and 1.0.0 (30-Oct-2002 to 01-Nov-2002)
+
+ o Consistently return SA_ERR_MEM instead of SA_ERR_SYS
+ if memory allocations failed.
+ [Ralf S. Engelschall]
+
+ o Various source tree cleanups.
+ [Ralf S. Engelschall]
+
+ o Cleanup markup in manual page (sa.pod)
+ [Ralf S. Engelschall]
+
+ o API Cleanups: use politically correct use "extern" keyword in sa.h;
+ use leading underscores for variables names in prototypes; move
+ "raddr" argument to second position in sa_{send,recv,sendf}.
+ [Ralf S. Engelschall]
+
+ Changes between 0.9.2 and 0.9.3 (11-Oct-2002 to 30-Oct-2002)
+
+ o Added a function sa_sendf(3) which is a convience wrapper
+ to sa_send(3) for sending formatted data. This is similar to what
+ sa_writef(3) does for sa_write(3). The difference is just that
+ sa_writef(3) does not need a temporary buffer (because can use the
+ stream I/O write buffer) while sa_sendf(3) requires a temporary
+ buffer for its operation. Nevertheless the temporary buffer is
+ allocated only if the formatted data is large. For small formatted
+ data a fast stack-based buffer is used for higher performance.
+ [Ralf S. Engelschall]
+
+ o Finished implementation of test suite in order to cover
+ mostly all functionality of the API.
+ [Ralf S. Engelschall]
+
+ o Rewrote the implementation of sa_option(3) in order to make options
+ configurable _before_ the underlying socket is implicitly
+ allocated. This fixes especially sa_option(sa, SA_OPTION_REUSEADDR, 1)
+ before sa_bind().
+ [Ralf S. Engelschall, Michael van Elst <mlelstv@dev.de.cw.net>]
+
+ o Finished writing the documentation (manual page sa.pod).
+ [Ralf S. Engelschall]
+
+ o Fixed return code and error handling in sa_read(3).
+ [Ulrich Dessauer <udessauer@agnitas.de>]
+
+ o Upgraded build environment to GNU autoconf 2.54 and GNU libtool 1.4.3.
+ [Ralf S. Engelschall]
+
+ o Source tree cleanups and polishing.
+ [Ralf S. Engelschall]
+
+ Changes between 0.9.1 and 0.9.2 (15-Mar-2002 to 11-Oct-2002)
+
+ o Check for inet_addr, inet_aton, inet_pton, inet_ntoa and inet_ntop
+ under configure time and use this to use reasonable fallbacks for
+ the underlying usage of address manipulation functions.
+ [Ralf S. Engelschall]
+
+ o Upgraded build environment to GNU shtool 1.6.1.
+ [Ralf S. Engelschall]
+
+ o Fixed "make realclean" target.
+ [Ralf S. Engelschall]
+
+ Changes between 0.9.0 and 0.9.1 (31-Jan-2002 to 15-Mar-2002)
+
+ o Removed gcc -ggdb3 option under --enable-debug.
+ [Ralf S. Engelschall]
+
+ o Upgraded build environment to GNU autoconf 2.53 and GNU shtool 1.6.0.
+ [Ralf S. Engelschall]
+
+ o Fixed internal snprintf implementation
+ [Ralf S. Engelschall]
+
+ o Fixed internal test suite library
+ [Ralf S. Engelschall]
