Log of Changes Made to CFITSIO Version 3.45 - May 2018 - New support for reading and writing unsigned long long datatypes. This includes 'implicit datatype conversion' between the unsigned long long datatype and all the other datatypes. - Increased the hardcoded NMAXFILES setting for maximum number of open files from 1000 to 10000. - Bug fix to fits_calc_binning wrapper function, which wasn't filling in the returned float variables. - Fixed a parsing bug for image subsection and column binning range specifiers that was introduced in v3.44. Version 3.44 - April 2018 - This release primarily patches security vulnerabilities. We strongly encourage this upgrade, particularly for those running CFITSIO in web accessible applications. In addition, the following enhancements and fixes were made: - Enhancement to 'template' and 'colfilter' functionality. It is now possible to delete multiple keywords using wildcard syntax. See "Column and Keyword Filtering Specification" section of manual for details. - histo.c uses double precision internally for all floating point binning; new double-precision subroutines fits_calc_binningd(), fits_rebin_wcsd(), and fits_make_histd(); existing single-precision histogram functions still work but convert values to double-precision internally. - new subroutine fits_copy_cols() / ffccls() to copy multiple columns - Fix in imcompress.c for HCOMPRESS and PLIO compression of unsigned short integers. - Fix to fits_insert_card(ffikey). It had wrongly been capitalizing letters that appeared before an '=' sign on a CONTINUE line. Version 3.43 - March 2018 The NASA security team requires the following warning to all users of CFITSIO: ===== The CFITSIO open source software project contains vulnerabilities that could allow a remote, unauthenticated attacker to take control of a server running the CFITSIO software. These vulnerabilities affect all servers and products running the CFITSIO software. The CFITSIO team has released software updates to address these vulnerabilities. There are no workarounds to address these vulnerabilities. In all cases, the CFITSIO team is recommending an immediate update to resolve the issues. ===== - Fixed security vulnerabilities. - Calls to https driver functions in cfileio.c need to be macro- protected by the HAVE_NET_SERVICES variable (as are the http and ftp driver function calls). Otherwise CMake builds on native Windows will fail since drvrnet.o is left empty. - Bug fix to ffmvec function. Should be resetting a local colptr variable after making a call to ffiblk (which can reallocate Ftpr-> tableptr). Originally reported by Willem van Straten. - Ignore any attempted request to not quantize an image before compressing it if the image has integer datatype pixels. - Improved error message construction throughout CFITSIO. Version 3.42 - August 2017 (Stand-alone release) - added https support to the collection of drivers handled in cfileio.c and drvrnet.c. This also handles the case where http transfers are rerouted to https. Note that this enhancement introduces a dependency on the libcurl development package. If this package is absent, CFITSIO will still build but will not have https capability. - made fix to imcomp_init_table function in imcompress.c. It now writes ZSIMPLE keyword only to a compressed image that will be placed in the primary header. - fix made to fits_get_col_display_width for case of a vector column of strings. Version 3.42 - March 2017 (Ftools release only) - in ftp_open_network and in ftp_file_exist, added code to repeatedly attempt to make a ftp connection if the ftp server does not respond to the first request. (some ftp servers don't appear to be 100% reliable). - in drvrnet.c added many calls to 'fclose' to close unneeded files, to avoid exceeding the maximum allowed number of files that can be open at once. - made substantial changes to the ftp_checkfile and http_checkfile routines to streamline the process of checking for the existence of a .gz or .Z compressed version of the file before opening the uncompressed file (when using http or ftp to open the file). - modified the code in ftp_open_network to send "\r\n" as end-of-line characters instead of just "\n". Some ftp servers (in particular, at heasarc.gsfc.nasa.gov) now require both characters, otherwise the network connection simply hangs. - modified the http_open_network routine to handle HTTP 301 or 302 redirects to a FTP url. This is needed to support the new configuration on the heasarc HTTP server which sometimes redirects http URLS to a ftp URL. Version 3.41 - November 2016 - The change made in version 3.40 to include strings.h caused problems on Windows (and other) platforms, so this change was backed out. The reason for including it was to define the strcasecmp and strcasencmp functions, so as an alternative, new equivalent functions called fits_strcasecmp and fits_strncasecmp have been added to CFITSIO.as a substitute. All the previous calls to the str[n]casecmp functions have been changed to now call fits_str[n]casecmp. In addition, the previously defined ngp_strcasecmp function (in grparser.c) has been removed and the calls to it have been changed to fits_strcasecmp. - The speed.c utility program was changed to correctly call the gettimeofday function with a NULL second arguement. Version 3.40 - October 2016 - fixed a bug when writing long string keywords with the CONTINUE convention which caused the CONTINUE'd strings to only be 16 characters long, instead of using up all the available space in the 80-character header record. - fixed a missing 'defined' keyword in fitsio.h. - replaced all calls to strtok (which is not threadsafe) with a new ffstrtok function which internally calls the threadsafe strtok_r function. One byproduct of this change is that <strings.h> must also be included in several of the C source code files. - modified the ffphbn function in putkey.c to support TFORM specifiers that use lowercase 'p' (instead of uppercase) when referring to a variable-length array column. - modified the lexical parser in eval.y and eval_y.c to support bit array columns (with TFORMn = 'X') with greater than 256 elements. Fix to bitcmp function: The internal 'stream' array is now allocated dynamically rather than statically fixed at size 256. This was failing when users attempted a row filtering of a bitcol that was wider than 256X. In bitlgte, bitand, and bitor functions, replaced static stream[256] array allocation with dynamic allocation. - modified the ffiter function in putcol.c to fix a problem which could cause the iterator function to incorrectly deal with null values. This only affected TLONG type columns in cases where sizeof(long) = 8, as well as for TLONGLONG type columns. - Fix made to uncompress2mem function in zcomprss.c for case where output uncompressed file expands to over the 2^32 (4Gb) limit. It now checks for this case at the start, and implements a 4Gb paging system through the output buffer. The problem was specifically caused by the d_stream.avail_out member being of 4-byte type uInt, and thus unable to handle any memory position values above 4Gb. - fixed a bug in fpackutil.c when using the -i2f (integer to float) option in fpack to c
