Largest blocks are trimmed first. * rescuebook.cc: Largest blocks are now split first until logfile reaches '--logfile-size' entries. * logbook.cc (extend_sblock_vector, truncate_vector): Terminate if truncation would discard finished blocks. * rescuebook.cc: Mark failed blocks with 1 sector as bad-sector. * logbook.cc (extend_sblock_vector): Remove last block of logfile if it starts at isize and is not marked as finished. * io.cc (show_status,update_rates): Detect a jump back in time and adjust status. * ddrescue.h (slow_read): Return false for the first 10 seconds. * io.cc (show_status) Leave cursor after message so that ^C does not overwrite it. * main.cc: Do not require '--force' for generate mode. * ddrescue.h (Logbook::logfile_exists): Do not return false if logfile exists but is empty. * Added new chapter 'Using ddrescue safely' to the manual. * Documented that 'direct disc access' only reads whole sectors. * configure: Options now accept a separate argument. * Makefile.in: Added new target 'install-bin'. 2012-06-11 Antonio Diaz Diaz <ant_diaz@teleline.es> * Version 1.16 released. * Added new option '-K, --skip-size'. * Added new option '-T, --timeout'. * Changed short name of option '--try-again' to '-A'. * Maximum skip size is now limited to 1% of infile size or 1 GiB (whichever is smaller), rounded to the next multiple of sector size. * Set current_pos to end of block when reading backwards. * The '-E, --max-error-rate' option now checks the rate of actually failed reads, not the growth of error size. * The option '-v, --verbose' now increases verbosity if repeated. * Changed quote characters in messages as advised by GNU Standards. * configure: 'datadir' renamed to 'datarootdir'. * New files rational.h, rational.cc. 2012-01-01 Antonio Diaz Diaz <ant_diaz@teleline.es> * Version 1.15 released. * Added new option '-a, --min-read-rate'. * Added new option '-I, --verify-input-size'. * Added new option '-x, --extend-outfile'. * main.cc: Verify that infile, outfile and logfile are all different. * Non-tried blocks are now read aligned to cluster-size sectors. * rescuebook.cc: Improved skip algorithm for the split pass. * main.cc: Removed spurious warning about '-D' ignored in fill mode. * ddrescue.texinfo: Improved description of algorithm. * logbook.cc (change_chunk_status): Return an adjust value (-1, 0, 1) to keep "errors" updated without calling count_errors every time. * ddrescue.cc: Renamed to io.cc. * Added 'ddrescuelog', a program for logfile manipulation. 2011-01-10 Antonio Diaz Diaz <ant_diaz@teleline.es> * Version 1.14 released. * Added new option '-R, --reverse'. * Added new option '-E, --max-error-rate'. * Extended syntax '--max-errors=+N' to specify new errors. * Changed short name of option '--retrim' to '-M'. * Removed spurious warning about 'preallocation not available'. * Code reorganization.
