Eliminating it reduces the number of false -positives for corruption and makes error detection more accurate). - -When decompressing, the file specified with the '--output' option is now -deleted if the input is a terminal. - -"--merge", "--range-decompress", "--repair" and "--split" now preserve -dates, permissions, and, when possible, ownership of the files created -just as "--decompress" does. - -Dictionary size and size of trailing data (if any) are now printed when -"-lv" is specified. - -The new option "-A, --alone-to-lz", which converts lzma-alone files to -lzip format without recompressing, just adding a lzip header and -trailer, has been added. Only streamed files with default LZMA -properties can be converted; non-streamed lzma-alone files lack the end -of stream marker required in lzip files. - -The new option "-W, --debug-decompress=<pos>,<val>", which sets the byte -<pos> to the value <val> and then decompresses to stdout the resulting -corrupt data, has been added. - -The new option "-X, --show-packets", which shows the LZMA packets -(coding sequences) coded in a given file, has been added. - -The short name of option "--debug-delay" has been changed to "-Y". - -The short name of option "--debug-repair" has been changed to "-Z". - -The new options "-B, --block", "-d, --delta", "-t, --truncate" and "-z, ---zcmp" have been added to unzcrash. - -Unzcrash now can read files as large as RAM allows. - -Unzcrash now compares the output of the decompressor for the original -and corrupt files when the decompressor returns with zero status. For -this unzcrash needs a 'zcmp' program able to understand the format being -tested. For example the one provided by 'zutils'. - -Unzcrash now accepts negative position (relative to the end of file) and -negative size (relative to the rest of the file). - -The new chapter "Trailing data" has been added to the manual. - -A harmless check failure on Windows, caused by the failed comparison of -a message in text mode, has been fixed. +Trailing data are now shown both in hexadecimal and as a string of +printable ASCII characters. |
