./archivers/lziprecover, Recovery tool for lossless data compressor based on the LZMA algorithm

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 1.19, Package name: lziprecover-1.19, Maintainer: pkgsrc-users

Lziprecover is a data recovery tool and decompressor for files in the
lzip compressed data format (.lz) able to repair slightly damaged files,
recover badly damaged files from two or more copies, extract undamaged
members from multi-member files, decompress files and test integrity of
files.

Lziprecover is able to recover or decompress files produced by any of
the compressors in the lzip family; lzip, plzip, minilzip/lzlib, clzip
and pdlzip. This recovery capability contributes to make the lzip format
one of the best options for long-term data archiving.

Lziprecover is able to efficiently extract a range of bytes from a
multi-member file, because it only decompresses the members containing
the desired data.

Log message:
Changes in version 1.19:

'--merge' is now able to fix files with thousands of scattered errors
per member by grouping the errors into clusters and then merging the
files as if each cluster were a single error.

The option '-a, --trailing-error' now works with '-l, --list' and
'-D, --range-decompress'.

The output of option '-l, --list' has been simplified to make it easier
to read.

In test mode, lziprecover now continues checking the rest of the files
if any input file is a terminal.

Trailing data are now shown both in hexadecimal and as a string of
printable ASCII characters.

        * lzip.texi: Added chapter 'Trailing data'.
        * configure: Avoid warning on some shells when testing for g++.

Log message:
Update to 1.16:

Changes in version 1.16:

Repairing of single-byte errors is now about 10 times faster depending
on file size and position of error.

Copying of file dates, permissions, and ownership now behaves like "cp -p".
(If the user ID or the group ID can't be duplicated, the file permission
bits S_ISUID and S_ISGID are cleared).

Some minor improvements have been made.

"lziprecover.texinfo" has been renamed to "lziprecover.texi".

The license has been changed to GPL version 2 or later.

Log message:
Update to 1.15:

Changes in version 1.15:

Lziprecover can now repair multi-member files with up to one byte error
per member, without having to split them first.

Lziprecover can now merge multi-member files without having to split
them first even if some copies have the header and the trailer damaged.

The chapters "Repairing files", "Merging files" and \ 
"Unzcrash" have been
added to the manual.
