The following packages have been uploaded to the Cygwin distribution:

* ddrescue-1.27-1

GNU ddrescue is a data recovery tool.  It copies data from
one file or block device (hard disc, cdrom, etc) to another, trying
hard to rescue data in case of read errors.  Ddrescue does not
truncate the output file if not asked to.  So, every time you run
it on the same output file, it tries to fill in the gaps.

https://www.gnu.org/software/ddrescue/ddrescue.html

This is an update to the latest upstream release.

- Changes in version 1.27:

A deadlock in command mode when stdout is fully buffered has been fixed by
flushing stdout after executing each command.

The new option '-W, --compare-before-write' has been added. It omits
superfluous writes in rescue mode.

Diagnostics caused by invalid arguments to command line options now show the
argument and the name of the option.

The option synonym '--direct' has been removed and is no longer recognized.

'long long' is now used instead of 'long' for time variables.

- Changes in version 1.26:

While writing the mapfile, ddrescue now checks the return value of each call
to 'fprintf' to catch any temporary failure of 'fprintf' not reported by the
system when closing the file.

Domain mapfiles may now contain unordered and overlapping blocks when
'-L, --loose-domain' is specified as long as no block overlaps with other
block of different status.

Ddrescue now shows the file name in all the diagnostics with a file 
involved.

Ddrescue now exits with status 1 on fatal read errors.

Empty phases are now completely skipped.

Ddrescue now scrolls forward after each pass. This keeps on the screen the
final status of the previous pass, making it easier to estimate the amount
of work done by the current pass.

In case of error in a numerical argument to a command line option, ddrescue
now shows the name of the option and the range of valid values.

The option synonyms '--*-logfile' and '--pause' have been removed and are no
longer recognized.

Ddrescuelog now can convert between mapfiles and bitmaps of blocks (big and
little endian). The new option '-F, --format' has been added to ddrescuelog.
It selects the input format for '--create-mapfile', or the output format for
'--list-blocks'.

Option '-d, --delete-if-done' of ddrescuelog no longer returns an error if
the mapfile is read from standard input. Instead it behaves like
'-D, --done-status' because there is nothing to delete.

'ddrescuelog --show-status' now rounds percentages up to get the sum closer
to 100%.

The description of the algorithm in the manual has been improved.

Regards,
Christian Franke
