    Added strings.c to build.

2003-01-25  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * src/xi.c
    Read seems to be working so looking at write.

    * src/sndfile.h.in
    Added SF_FORMAT_XI, SF_FORMAT_DPCM_8 and SF_FORMAT_DPCM_16 enum values.

    * tests/floating_point_test.c tests/lossy_comp_test.c tests/Makefile.am
    Added test for 8 and 16 bit XI format files.

2003-01-24  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    Added a non-lawyer readable summary of the licensing provisions as
    suggested by Steve Dekorte.

2003-01-23  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

2003-01-15  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * examples/sndfile-play.c examples/sndfile-info.c
    When run on Win32 without any command line parameters print a message and
    then sleep for 5 seconds. This means the when somebody double clicks on
    these programs in explorer the user will actually see the message.

2003-01-14  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * tests/misc_test.c
    Bypass permission test if running as root because root is allowed to open
    a readonly file for write.

    * Win32/Makefile.msvc
    Added pvf.c and xi.c source files to project.

    * src/sndfile.h
    Updated for PVF files.

2003-01-07  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    Hooked in new file xi.c.

2002-12-30  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * src/rx2.c
    Added a patch from Marek Peteraj which sheds a little more light on the
    slices within an RX2 file. Still need to find out data encoding.

2002-12-20  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * src/wav.c
    Started work on decoding 'acid' and 'strc' chunks.

2002-12-14  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * tests/peak_check_test.c
    Minor cleanup.

2002-12-12  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * tests/write_read_test.tpl
    Added check to make sure no error was generated when an attempt was made to
    read past the end of the file.

2002-12-11  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * doc/lists.html
    Added "mailto" links for all three lists.

    * src/pvf.c
    New file for Portable Voice Format files.

    * src/sndfile.h.in src/sndfile.c src/common.h src/command.c src/Makefile.am
    Added hooks for SF_FORMAT_PVF format files.

    * tests/write_read_test.tpl tests/std*.c
    Add tests for SF_FORMAT_PVF.

    * doc/index.html
    Add PVF to the compatibility matrix.

    * src/pcm.c src/alaw.c src/ulaw.c src/float32.c src/double64.c
    Previously, attempts to read beyond the end of a file would set psf->error
    to SFE_SHORT_ERROR. This behaviour diverged from the behaviour of the POSIX
    read() call but has now been fixed.
    Attempts to read beyond the end of the file will return a short read count
    but will not longer set any error.

2002-12-09  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * src/sndfile.c
    Add more sanity checking when opening a RAW file for read. When format is
    not RAW, zero out all members of the SF_INFO struct.

    * tests/raw_test.c
    Add bad_raw_test() to check for above problem.

    * tests/stdin_test.c examples/sndfile-info.c
    Set the format field of the SF_INFO struct to zero before calling
    sf_open().

    * doc/api.html
    Add information about the need to set the format field of the SF_INFO struct
    to zero when opening non-RAW files for read.

    * configure.ac
    Removed use of conversion script on Solaris. Not all Solaris versions
    support it.

    * doc/lists.html
    New file containg details of the mailing lists.

    * doc/index.html
    Add a link to the above new file.

2002-12-04  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * tests/dft_cmp.c
    Fixed a SIGFPE on Alpha caused by a log10 (0.0). Thanks to Joshua Haberman
    for providing the gdb traceback.

2002-11-28  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * src/wav.c
    Added more capabilities to 'smpl' chunk parser.

    * src/sndfile.c
    Fixed some (not all) possible problems found with Flawfinder.

2002-11-24  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * src/sndfile.c
    Fixed a bug in sf_seek(). This bug could only occur when an attempt was
    made to read beyond the end and then sf_seek() was called with a whence
    parameter of SEEK_CUR.

    * src/file_io.c
    Win32's _fstati64() does not work, it returns BS. Re-implemented
    psf_get_filelen() in terms of psf_fseek().

    * tests/write_read_test.tpl
    Add a test to detect above bug.

    * src/float_cast.h
    Modification to prevent compiler warnings on Mac OS X.

    * src/file_io.c
    Fixes for windows (what a f**ked OS).

2002-11-08  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * configure.ac
    Disable use of native lrint()/lrintf() on Mac OSX. These functions exist on
    Mac OSX 10.2 but not on 10.1. Forcing the use of the versions in
    src/float_cast.h means that a library compiled on 10.2 will still work on
    10.1.

2002-11-06  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * configure.in configure.ac
    Renamed configure.in to configure.ac as expected by later versions of
    autoconf.
    Slight hacking of configure.ac to work with version 2.54 of autoconf.
    Changed to using -dumpversion instead of --version for determining GCC
    version numer as suggested by Anand Kumria.

    * src/G72x/Makefile.am
    Slight hacking required for operation with automake 1.6.3.

2002-11-05  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * src/common.c
    In psf_binheader_readf() changed type parameter type "b" type from size_t
    to int to prevent errors on IA64 CPU where sizeof (size_t) != sizeof (int).
    Thanks to Enrique Robledo Arnuncio for debugging this.

2002-11-04  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * test/command_test.tpl
    Changed test value so test would pass on Solaris.

    * src/Version_script.in
    Modified version numbering so that later versions of 1.0.X can replace
    earlier versions without recompilation.

    * src/vox_adpcm.c
    Fixed bug causing short reads.

2002-11-03  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * test/floating_point_test.c
    Code cleanup using functions from util.c.
    Add test for IEEE replacement floats and doubles.

2002-11-01  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * src/wav.c
    Fixed a possible divide by zero error when read the 'smpl' chunk. Thanks to
    Serg Repalov for the example file.

    * tests/pcm_test.tpl
    Used sf_command (SFC_TEST_IEEE_FLOAT_REPLACE) to test IEEE replacement code.
    Clean up pcm_double_test().

    * src/float32.c src/double64.c
    Force use of IEEE replacement code using psf->ieee_replace is TRUE,
    Print message to log_buffer as well.
    Rename all broken_read_* and broken_write* functions to replace_read_* and
    replace_write_*.

    * tests/util.tpl
    Added string_in_log_buffer().

    * tests/pcm_test.tpl
    Use string_in_log_buffer() to ensure that IEEE replacement code has been
    used.

    * configure.in
    Removed --enable-force-broken-float option. IEEE replacement code is now
    always tested.

2002-10-31  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * src/double64.c
    Implement code for read/writing IEEE doubles on platforms where the native
    double format is not IEEE.

    * src/float32.c src/common.h
    Remove float32_read() and float32_write(). Replace with float32_le_read(),
    float32_be_read(), float32_le_write() and float32_be_write() to match stuff
    in src/double64.c.

    * src/common.c
    Fix all usage of float32_write().

    * src/sndfile.h.in
    Added SFC_TEST_IEEE_FLOAT_REPLACE command (testing only).

    * src/common.h
    Added SF_PRIVATE field ieee_replace.

    * src/sndfile.c
    In sf_command() set/reset psf->ieee_replace.

2002-10-26  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * tests/pcm_test.tpl
    Fixed a problem when testing with --enable-force-broken-float. The test was
    generating a value of negative zero and the broken float code is not able
    to write negative zero. Removing the negative zero fixed the test.

2002-10-25  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * src/file_io.c
    Added fix for Cygwin (suggested by Maros Michalik).

2002-10-23  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * src/file_io.c
    Improved error detection and handling.

    * src/file_io.c src/common.h
    Removed functions psf_ferror() and psf_clearerr() which were redundant
    after above improvements.

    * src/aiff.c src/svx.c src/w64.c src/wav.c
    Removed all use of psf_ferror() and psf_clearerr().

    * src/sndfile.c
    Removed #include of <stdio.h>, <unistd.h>, <fcntl.h> and <math.h> which
    are no longer needed.

    * tests/misc_test.c
    Added test to make sure the correct error message is returned with an
    existing read-only file is openned for write.

    * src/vox_adpcm.c src/Makefile.am
    New file for handling OKI Dialogic ADPCM files.

    * src/sndfile.h
    Add new subtype SF_FORMAT_VOX_ADPCM.

    * src/sndfile.c
    Renamed function is_au_snd_file () to format_from_extenstion () and expanded
    its functionality to detect headerless VOX files.

    * src/raw.c
    Added hooks for SF_FORMAT_VOX_ADPCM.

    * examples/sndfile-info.c
    Print out file duration (suggested by Conrad Parker).

    * libsndfile.spec.in
    Force installation of sndfile.pc file (found by John Thompson).

    * tests/Makefile.am tests/lossy_comp_test.c tests/floating_point_test.c
    Add tests for SF_FORMAT_VOX_ADPCM.

2002-10-18  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * tests/misc_test.c
    Add test which attempts to write to /dev/full (on Linux anyway) to check
    for correct handling of writing to a full filesystem.

    * src/sndfile.c
    Return correct error message if the header cannot be written because the
    filesystem is full.

    * tests/util.tpl
    Corrected printing of file mode in error reporting.

    * src/mat5.c
    Fixed a bug where a MAT5 file written by libsndfile could not be opened by
    Octave 2.1.36.

2002-10-13  Erik de Castro Lopo  <erikd AT mega-nerd DOT com>

    * src/common.h src/file_io.c
    All low level file I/O have been modified to be better able to report
    system errors resulting from calling system level open/read/write etc.
