Changelog for libcfitsio-devel-3.350-13.1.x86_64.rpm :
Sun Jul 7 14:00:00 2013 asterios.dramisAATTgmail.com
- Update to version 3.350:

* fixed problem with the default tile size when compressing images with
fpack using the Hcompress algorithm.

* fixed returned value (\"status\" instead of \"
*status\")

* in imcompress.c, declared some arrays that are used to store the dimensions
of the image from \'int\' to \'long\', to support very large images (at least
on systems where sizeof(long) = 8),

* modified the routines that convert a string value to a float or double
to prevent them from returning a NaN or Inf value if the
string is \"NaN\" or \"Inf\" (as can happen with gcc implementation of the
strtod function).

* removed/replaced the use of the assert() functions when locking or
unlocking threads because they did not work correctly if NDEBUG is
defined.

* made modifications to the way the command-line file filters are parsed to
1) remove the 1024-character limit when specifying a column filter,
2) fixed a potential character buffer-overflow risk in fits_get_token, and
3) improved the parsing logic to remove any possible of confusing
2 slash characters (\"//\") in the string as the beginning of a
comment string.

* modified configure and Makefile.in so that when building CFITSIO
as a shared library on linux or Mac platforms, it will use the SONAME
convention to indicate whether each new release of the CFITSIO
library is binary-compatible with the previous version. Application
programs that link with the shared library will not need to be
recompiled as long as the versions are compatible. In practice,
this means that the shared library binary file that is created (on
Linux systems) will have a name like \'libcfitsio.so.I.J.K\', where I is the
SONAME version number, J is the major CFITSIO version number (e.g. 3),
and K is the minor CFITSIO version number (e.g., 34). Two link
files will also be created such that
libcfitsio.so -> libcfitsio.so.I, and
libcfitsio.so.I -> libcfitsio.I.J.K
Application programs will still run correctly with the new version of
CFITSIO as long as the \'I\' version number remains the same, but the
applications will fail to run if the \'I\' number changes, thus alerting
the user that the application must be rebuilt.

* fixed bug in fits_insert_col when computing the new table row width
when inserting a \'1Q\' variable length array column.

* modified the image compression routines so that the output compressed
image (stored in a FITS binary table) uses the \'1Q\' variable length
array format (instead of \'1P\') when the input file is larger than 4 GB.

* added support for \"compression directive\" keywords which indicate how
that HDU should be compressed (e.g., which compression algorithm to use,
what tiling pattern to use, etc.). The values of these keywords will
override the compression parameters that were specified on the command
line when running the fpack FITS file compression program.

* globally changed the variable and/or subroutine name \"dither_offset\"
to \"dither_seed\" and \"quantize_dither\" to \"quantize_method\" so
that the names more accurately reflects their purpose.

* added support for a new SUBTRACTIVE_DITHER_2 method when compressing
floating point images. The only difference with the previous method
is that pixels with a value exactly equal to 0.0 will not be dithered,
and instead will be exactly preserved when the image is compressed.

* added support for an alias of \"RICE_ONE\" for \"RICE_1\" as the value
of the ZCMPTYPE keyword, which gives the name of the image compression
algorithm. This alias is used if the new SUBTRACTIVE_DITHER_2 option
is used, to prevent old versions of funpack from creating a corrupted
uncompressed image file. Only newer versions of funpack will recognize
this alias and be able to uncompress the image.

* made performance improvement to fits_read_compressed_img so that
when reading a section of an compressed image that includes only
every nth pixel in some dimension, it will only uncompressed a tile
if there are actually any pixels of interest in that tile.

* fixed several issues with the beta FITS binary table compression code
that is used by fpack: added support for zero-length vector columns,
made improvements to the output report when using the -T option in fpack,
changed the default table compression method to \'Rice\' instead of
\'Best\', and now writes the \'ZTILELEN\' keyword to document the number
of table rows in each tile.

* fixed error in ffbinit in calculating the total length of the binary
table extension if the THEAP keyword was used to override the
default starting location of the heap.
- Removed cfitsio.patch (fixed upstream).
- Rebased cfitsio-zlib.patch to apply cleanly.
- Added a patch (no-return-in-nonvoid-function.patch) to fix \"Program returns
random data in a function\" rpm post build check error.

- aarch64-support.patch: Add support for aarch64

Wed Apr 3 14:00:00 2013 asterios.dramisAATTgmail.com
- Update to version 3.340:

* modified configure and configure.in to support cross-compiled cfitsio
as a static library for Windows on a Linux platform using MXE
(http://mxe.cc) - a build environment for mingw32. (contributed by
Niels Kristian Bech Jensen)

* added conditional compilation statementsfor the mingw32 environment in
drvrfile.c because mingw32 does not include the ftello and fseeko
functions. (contributed by Niels Kristian Bech Jensen)

* fixed a potential bug in ffcpcl (routine to copy a column from one table
to another table) when dealing with the rare case of a \'0X\' column (zero
length bit column).

* fixed an issue in the routines that update or modify string-valued
keyword values, as a result of the change to ffc2s in the previous
release. These routines would exit with a 204 error status if the
current value of the keyword to be updated or modified is null.

* fixed typo in the previous modification that was intended to ignore
numerical overflows in Hcompress when decompressing an image.

* moved the \'startcol\' static variable out of the ffgcnn routine and
instead added it as a member of the \'FITSfile\' structure that is defined
in fitsio.h. This removes a possible race condition in ffgcnn in
multi-threaded environments.
From version 3.330:

* modified the imcomp_decompress_tile routine to ignore any numerical
overflows that might occur when using Hcompress to decompress the
image. If Hcompress is used in its \'lossy\' mode, the uncompressed
image pixel values may slightly exceed the range of an integer
*2
variable. This is generally of no consequence, so we can safely ignore
any overflows in this case and just clip the values to the legal range.

* the default tiling pattern when writing a tile-compressed image
has been changed. The old behaviour was to compress the whole image
as one single large tile. This is often not optimal when dealing
with large images, so the new default behavior is to treat each
row of the image as one tile. This is the same default behavior
as in the standalone fpack program. The default tile size can
be overridden by calling fits_set_tile_dim.

* fixed bug bug that resulted in a corrupted output FITS image when
attempting to write a float or double array of values to a
tile-compressed integer data type image. CFITSIO does not support
implicit data type conversion in this case and now correctly
returns an appropriate error status.

* modified ricecomp.c to define the nonzero_count lookup table as an
external variable, rather then dynamically allocating it within the
3 routines that use it. This simplifies the code and eliminates the
need for special thread locking and unlocking statements. (Thanks to
Lars Kr. Lundin for this suggestion).

* modifed how the uncompressed size of a gzipped file is computed in the
mem_compress_open routine in drvrmem.c. Since gzip only uses 4 bytes
in the compressed file header to store the original file size, one may
need to apply a modulo 2^32 byte correction in some cases. The logic
here was modified to allow for corner cases (e.g., very small files, and
when running on 32-bit platforms that do not support files larger than
2^31 bytes in size).

* added new public routine to construct a 80 keyword record from the 3 input
component strings, i.e, the keyword name string, the value string, and
the comment string: fits_make_key/ffmkky. (This was already an undocumented
internal routine in previous versions of CFITSIO).

* modified ffc2s so that if the input keyword value string is a null string,
then it will return a VALUE_UNDEFINED (204) status value. This makes it
consistent with the behavior when attempting to read a null keyword
(which has no value) as a logical or as a number (which also returns
the 204 error). This should only affect cases where the header keyword
does not have an equal sign followed by a space character in columns 9
and 10 of the header record.

* Changed the \"char
*\" parameter declarations to \"const char
*\" in many
of the routines (mainly the routines that modify or update keywords) to
avoid compiler warnings or errors from C++ programs that tend to be more
rigorous about using \"const char
*\" when appropriate.

* added support for caching uncompressed image tiles, so that the tile does
not need to be uncompressed again if the application program wants
to read more data from the same tile. This required changes to the
main FITS file structure that is defined in fitsio.h, as well as
changes to imcompress.c.

* enhanced the previous modification to drvrfile.c to handle additional user
cases when running in the HEASARC\'s Hera environment.
From version 3.320:

* fixed flaw in the way logical columns (TFORM = \'L\') in binary tables
were read which caused an illegal value of 1 in the column to be
interpreted as a \'T\' (TRUE) value.

* extended the column filtering syntax in the CFITSIO file name parser to
enable users and scripts to append new COMMENT or HISTORY keyword into the
header of the filtered file (provided by Craig Markwardt). For example,
fcopy \"infile.fits[col #HISTORY=\'Processed on 2012-10-05\']\" outfile.fits
will append this header keyword: \"HISTORY Processed on 2012-10-05\"

* small change to the code that opens and reads an ASCII region file to
return an error if the file is empty.

* fixed obscure sign propagation error when attempting to read the
uncompressed size of a gzipped FITS file. This resulted in a memory
allocation error if the gzipped file had an uncompressed file
size between 2^31 and 2^32 bytes. Fix supplied by Gudlaugur Johannesson
(Stanford).
- Rebased cfitsio.patch to apply cleanly.

Tue Jul 31 14:00:00 2012 asterios.dramisAATTgmail.com
- Update to version 3.310:

* Enhanced the CFITSIO column filtering syntax to allow the comma, in
addition to the semi-colon, to be used to separate clauses, for example:
[col X,Y;Z = max(X,Y)]. This was done because users are not allowed to
enter the semi-colon character in the on-line Hera data processing
system due to computer security concerns.

* Enhanced the CFITSIO extended filename syntax to allow specifying image
compression parameters (e.g. \'[compress Rice]\') when opening an existing
FITS file with write access. The specified compression parameters will
be used by default if more images are appended to the existing file.

* Modified drvrfile.c to do additional file secrity checks when CFITSIO
is running within the HEASARC\'s Hera software system. In this case
CFITSIO will not allow FITS files to be created outside of the user\'s
individual Hera data directory area.

* Fixed an issue in fpack and funpack on Windows machines, caused by
the fact that the \'rename\' function behaves differently on Windows
in that it does not clobber an existing file, as it does on Unix
platforms.

* Fixed bug in the way byte-swapping was being performed when writing
integer
*8 null values to an image or binary table column.

* Added the missing macro definition for fffree to fitsio.h.

* Modified the low level table read and write functions in getcol
*.c and
putcol
*.c to remove the 32-bit limitation on the number of elements.
These routines now support reading and writing more than 2
*
*31 elements
at one time. Thanks to Keh-Cheng Chu (Stanford U.) for the patch.

* Modified Makefile.in so that the shared libcfitsio.so is linked against
pthreads and libm.
- Removed the fix to link the library to libpthread and libm from cfitsio.patch
(fixed upstream).
- Rebased cfitsio-zlib.patch to apply cleanly. Removed the linking of the
programs (fpack and funpack) to libz from the patch (not needed).
- Remove some more bundled zlib files from the package.

Wed May 9 14:00:00 2012 asterios.dramisAATTgmail.com
- Renamed package from libcfitsio0 to cfitsio.
- Renamed subpackage libcfitsio-doc to libcfitsio-devel-doc (added obsoletes
entry for libcfitsio-doc of previous openSUSE versions).
- Suggest the libcfitsio-devel-doc package in libcfitsio-devel.
- Removed the requirement for libcfitsio0 from libcfitsio-(devel)-doc (not
needed).

Tue May 8 14:00:00 2012 asterios.dramisAATTgmail.com
- Update to version 3.300:
Enhancements

* Added new routine called fits_is_reentrant which returns 1 or 0 depending
on whether or not CFITSIO was compiled with the -D_REENTRANT directive.
This can be used to determine if it is safe to use CFITSIO in
multi-threaded programs.

* Implimented much faster byte-swapping algorithms in swapproc.c based on
code provided by Julian Taylor at ESO, Garching. These routines
significantly improve the FITS image read and write speed (by more than a
factor of 2 in some cases) on little-endian machines (e.g., Linux and
Microsoft Windows running on x86 PCs) where byte-swapping is required.
This has no effect on big-endian machines (e.g., Macs). Even faster
performance can be achieved in some cases by invoking the new
\"--enable-sse2\" or \"--enable-ssse3\" configure options when building CFITSIO
on machines that have CPUs and compilers that support the SSE2 and SSSE3
machine instructions.

* added additional support for implicit data type conversion in cases where
the floating point image has been losslessly compressed with gzip. The
pixels in these compressed images can now be read back as arrays of short,
int, and long integers as well as single and double precision
floating-point.

* modified fitsio2.h and f77_wrap.h to recognize IBM System z mainframes by
testing if __s390x__ or __s390__ is defined.

* small change to ffgcrd in getkey.c so that it supports reading a blank
keyword (e.g., a keyword whose name simply contains 8 space chracters).
Bug Fixes

* fixed a bug in imcomp_decompress_tile that caused the tile-compressed image
to be uncompressed incorrectly (even though the tile-compressed image
itself was written correctly) under the following specific conditions:
- the original FITS image has a \"float\" datatype (R
*4)
- one or more of the image tiles cannot be compressed using the standard
quantization method and instead are losslessly compressed with gzip
- the pixels in these tiles are not all equal to zero (this bug does
affect tiles where all the pixels are equal to zero)
- the program that is reading the compressed image uses CFITSIO\'s
\"implicit datatype conversion\" feature to read the \"float\" image
back into an array of \"double\" pixel values.
If all these conditions are met, then the returned pixel values in the
affected image tiles will be garbage, with values often ranging
up to 10
*
*34. Note that this bug does not affect the fpack/funpack
programs, because funpack does not use CFITSIO\'s implicit datatype
conversion feature when uncompressing the image.
- Replaced cfitsio-makefile.patch with cfitsio.patch (taken from Fedora). It\'s
the same patch with the addition of linking libcfitsio with libpthread and
libm (fixes possible errors with packages requiring libcfitsio0 and compiled
with the \"--as-needed\" flag).
- Added a patch (cfitsio-zlib.patch) to use system zlib (based on patches from
Fedora and Debian). Added zlib-devel in build depencdencies.
- Added a patch (implicit-pointer-decl.patch) to fix \"implicit-pointer-decl\"
rpm post build check warning.
- Moved \"-lpthread\" and added \"-lz\" in Libs.private: of cfitsio pkg-config
file.
- Removed \"-fno-strict-aliasing\" from CFLAGS.
- Don\'t install static libraries.

Sun Dec 4 13:00:00 2011 asterios.dramisAATTgmail.com
- Update to version 3.290:
Enhancements

* modified Makefile.in to allow configure to override the lib and include
destination directories.

* added (or restored actually) support for tile compression of 1-byte integer
images in imcomp_compress_tile. Support for that data type was overlooked
during recent updates to this routine.

* modified the fits_get_token command-line parsing routine to perform more
rigorous checks to determine if the token can be interpreted as a number
or not.

* made small modification to fpack.c to not allow the -i2f option (convert
image from integer to floating point) with the \"-g -q 0\" option (do lossless
gzip compression). It is more efficient to simply use the -g option alone.

* made modifications to fitsio.h and drvrfile.c to support reading and
writing large FITS files (> 2.1 GB) when building CFITSIO using
Microsoft Visual C++ on Windows platforms.

* added new WCS routine (ffgicsa) which returns the WCS keyword values
for a particular WCS version (\'A\' - \'Z\').
Bug Fixes

* fixed a problem with multi-threaded apps that open/close FITS files
simultaneously by putting mutex locks around the call to
fits_already_open and in fits_clear_Fptr.

* fixed a bug when using the \'regfilter\' function to select a subset of the
rows in a FITS table that have coordinates that lie within a specified
spatial region on the sky. This bug only affects the rarely used panda
(and epanda and bpanda) region shapes in which the region is defined by
the intersection of an annulus and a pie-shaped wedge. The previous code
(starting with version 3.181 of CFITSIO where support for the panda region
was first introduced) only worked correctly if the 2 angles that define
the wedge have values between -180 and +180. If not, then fewer rows than
expected may have been selected from the table.

* fixed the extended filename parser so that when creating a histogram by
binning 2 table columns, if a keyword or column name is given as the
weighting factor, then the output histrogram image will have a floating
point datatype, not the default integer datatype as is the case when no
weigth is specified (e.g. with a filename like
\"myfile.fits[bin x,y; weight_column]\"

* added fix to the code in imcompress.c to work around a problem with
dereferencing the value of a pointer, in cases where the address of
that pointer has not been defined (e.g., the nulval variable).

* modified the byte shuffling algorithm in fits_shuffle_8bytes to work
around a strange bug in the proprietary SunStudioExpress C compiler
under OpenSolaris.

* removed spurious messages on the CFITSIO error stack when opening a
FITS file with FTP (in drvrnet.c);
- Removed the Makefile.in changes from cfitsio-makefile.patch (fixed upstream).
- Spec file updates:

* Changed License entry to SPDX style.

* Enable multithreading support.
