See git log at https://code.google.com/p/diskscrub/ 2008-11-14 Jim Garlick <garlick@llnl.gov> * : tag scrub-2.1 * src/sig.c : Fix a bug where uninitialized malloc buffer was written to first block of file/device when writing signature. That buffer could contain some data from the original file. This bug was introduced with scrub 1.8 on 2006-08-16. * tests/t14 : Test for above regression. * tests/pat.c : Utility program for above test. 2008-06-03 Jim Garlick <garlick@llnl.gov> * htdocs/index.html : Add SF logo per policy. 2008-05-30 Jim Garlick <garlick@llnl.gov> * : tag scrub-2.0 * src/scrub.c : Drop warning about zero length resource fork to address failing tests on darwin. * test/t10-marklar.exp : Add test for checking disk size on darwin. 2008-05-28 Jim Garlick <garlick@llnl.gov> * scrub.spec : Set --program-prefix to prevent AIX from adding one. 2008-05-27 Jim Garlick <garlick@llnl.gov> * test/pad.c, src/scrub.c, src/getsize.c : Eliminate warnings on HP-UX 11. 2008-05-26 Jim Garlick <garlick@llnl.gov> * src/fillfile.[ch] : Get rid of growfile(). Add ENOSPC handling to fillfile(). Elminiate is_char() and instead call filetype(). * src/scrub.c : Re-implement scrub -X to create many ulimit-size files in a directory rather than one big file. * src/progress.[ch] : Fill remaining progress-space with 'x' if progress_destroy() is called with < 100% complete. * src/util.[ch] : Move bool definition, filetype(), and blkalign() from scrub.c. Add an UP|DOWN parameter to blkalign. Split filetype() return value SPECIAL into BLOCK and CHAR. 2008-05-25 Jim Garlick <garlick@llnl.gov> * src/scrub.1 : Add longopts to option description. * src/scrub.c : Add longopts to usage message. * src/scrub.c : Add support for Gutmann pattern sequence. * src/pattern.[ch] : Factor out pattern handling stuff from scrub.c. * test/t11 : New, verify Gutmann sequence. * src/scrub.c : Allow -s on a regular file for testing. * test/t12 : New, ensure -s grows a file to the correct size. 2008-05-21 Jim Garlick <garlick@llnl.gov> * : tag scrub-1.10 * test/* : Add test infrastructure. * src/scrub.c : Add --test-sparse option. * src/* : Replace perror() with strerror(errno). * src/fillfile.c : Fix a bug where file argument to -X had to exist. 2008-05-20 Jim Garlick <garlick@llnl.gov> * : Integrated automake/autoconf. * htdocs/* : Added small web page. * src/scrub.c : Put main() at the top and add getopt_long() support. * src/*.c : Large file support through autoconf. 2007-09-26 Jim Garlick <garlick@llnl.gov> * scrub.c, scrub.1 : Added -v option [suggested by Daniel Hoit]. 2007-03-30 Jim Garlick <garlick@llnl.gov> * fillfile.c : Open with O_SYNC instead of calling fsync() periodically on non-char-special files. 2007-03-20 Jim Garlick <garlick@llnl.gov> * : tag scrub-1.9 * progress.c : Fflush stdout in the batch case so progress can still be assessed by looking at log file [reported by Jim Harm]. 2007-01-28 Jim Garlick <garlick@llnl.gov> * getsize.c : Handle > 2TB device size in Linux. 2007-01-18 Jim Garlick <garlick@llnl.gov> * scrub.c, scrub.1 : Changed default blocksize to 1M [Graham Smith]. * getsize.c : Cleanup [Graham Smith]. 2007-01-05 Jim Garlick <garlick@llnl.gov> * scrub.c : Add -r option to unlink file after scrub [Sean Morrison]. 2006-12-28 Jim Garlick <garlick@llnl.gov> * getsize.c : Added getsize() implementation for hpux [Graham Smith]. 2006-11-27 Jim Garlick <garlick@llnl.gov> * scrub.c : Refuse to scrub a zero length file (avoids assertion failure in progress.c) [Markus Schatzl]. 2006-11-22 Jim Garlick <garlick@llnl.gov> * scrub.c : Change sprintf's to snprintf [Markus Schatzl]. 2006-10-18 Jim Garlick <garlick@llnl.gov> * : add __hpux to large file ifdef * getsize.c : use sscanf("%llu") instead of strtoull for hpux portability. 2006-08-17 Jim Garlick <garlick@llnl.gov> * getsize.c: Fixed logic error in main (only affects test prog). 2006-08-16 Jim Garlick <garlick@llnl.gov> * NEWS: Renamed README. * scrub.c: Added -S option to skip writing scrub signature. * : tag scrub-1.8 2006-08-07 Jim Garlick <garlick@llnl.gov> * getsize.c: Added str2int(). * scrub.c: Call str2int() to parse blocksize arg. 2006-08-04 Jim Garlick <garlick@llnl.gov> * scrub.spec: Minor change to support building RPM's on AIX. * : make error reporting more verbose all around. 2006-08-03 Jim Garlick <garlick@llnl.gov> * Makefile: Add CC, CFLAGS, LDADD for AIX compilers. * sig.c: Fix typo. * pad.c, sig.c: Add large file includes. 2006-07-28 Jim Garlick <garlick@llnl.gov> * sig.[ch]: Read/write even blocksize multiples for AIX. 2006-07-23 Jim Garlick <garlick@llnl.gov> * scrub.c: Emit a warning if off_t is not 64 bits. * scrub.c, filldentry.[ch]: Use int instead of char for pattern array elements, and encode VERIFY and RANDOM in high bits to allow for all possible byte values in a pattern, * sig.[ch]: New. * scrub.c: Refuse to scrub a previously scrubbed file, unless the -f option is specified. * getsize.c: Clean up size2str(), silence compiler warnings. * scrub.c: Abort before progress bar display if no permission. 2006-07-17 Jim Garlick <garlick@llnl.gov> * fillfile.c: Only fsync() regular files. * scrub.c: Change scrub_disk() size argument from size_t to off_t, yet another 32 bit truncation bug on some systems. 2006-07-07 Jim Garlick <garlick@llnl.gov> * getsize.c: Fix truncation bug in AIX getsize(). * scrub.c, getsize.c: Fix truncation bug in -s option handling.
