Trailing data (if any) are saved alone in the last +file. (Gaps may contain garbage or may be members with corrupt headers or +trailers). -The test used by lziprecover to discriminate trailing data from a corrupt -header in multimember or concatenated files has been improved to a -Hamming distance (HD) of 3, and the 3 bit flips must happen in different -magic bytes for the test to fail. As a consequence some kinds of files -no longer can be appended to a lzip file as trailing data unless the -'--loose-trailing' option is used when decompressing. -Lziprecover can be used to remove conflicting trailing data from a file. +'--ignore-errors' now makes '--list' show gaps between members, ignoring +format errors. -The contents of a corrupt or truncated header found in a multimember -file is now shown, after the error message, in the same format as -trailing data. +'--ignore-errors' now makes '--range-decompress' ignore a truncated last +member. -The 'bits/byte' ratio has been replaced with the inverse compression -ratio in the output. +Errors are now also checked when closing the input file in decompression +mode. -The progress of decompression is now shown at verbosity level 2 (-vv) or -higher. +Some diagnostic messages have been improved. -Progress of decompression is only shown if stderr is a terminal. +'\n' is now printed instead of '\r' when showing progress of merge or repair +if stdout is not a terminal. -A final diagnostic is now shown at verbosity level 1 (-v) or higher if -any file fails the test when testing multiple files. +Lziprecover now compiles on DOS with DJGPP. (Patch from Robert Riebisch). -In case of (de)compressed size mismatch, the stored size is now also -shown in hexadecimal to ease visual comparison. +The new chapter 'Tarlz', explaining the ways in which lziprecover can +recover and process multimember tar.lz archives, has been added to the +manual. -The dictionary size is now shown at verbosity level 4 (-vvvv) when -decompressing or testing. +The configure script now accepts appending options to CXXFLAGS using the +syntax 'CXXFLAGS+=OPTIONS'. + +It has been documented in INSTALL the use of +CXXFLAGS+='-D __USE_MINGW_ANSI_STDIO' when compiling on MinGW. |
