[ANNOUNCEMENT] Updated: findutils-4.3.1-1

Hash: SHA1

A new release of findutils, 4.3.1-1, is available, replacing 4.3.0-2 as

This is a new development upstream release.  Although it is still marked
beta upstream, it has proven to be more reliable than the stable 4.2.x
series on cygwin.  As a beta release, it adds new optimization features
that might be withdrawn depending on feedback received.  Upstream news
since 4.3.0 is attached, see also /usr/share/doc/findutils-4.3.1/.

The findutils package contains programs which will help you locate files
on your system.  The find utility searches through a hierarchy of
directories looking for files which match a certain set of criteria (such
as a filename pattern).  The xargs utility builds and executes command
lines from standard input arguments (usually lists of file names generated
by the find command).  The locate utility scans a database of filenames
and displays matches.  The updatedb utility builds the database for locate.

To update your installation, click on the "Install Cygwin now" link on the web page.  This downloads setup.exe to your system.
Save it and run setup, answer the questions and pick up 'findutils' from
the 'Base' category (it should already be selected).

Note that downloads from (aka aren't

** Bug Fixes

Find now follows POSIX rules for determining where directories end and
expressions start.  This means that "find \(1 \!2 \, \)" now searches
in the four named directories, rather than trying to parse an
expression. (Savannah bug #15235).

You now get a more helpful error message when you use command lines
which have missing expressions, such as 
      find . ( )
      find . !
      find . -a
      find . \( -not \)
      find . \( -true -a

Savannah bug #15800: If find finds more subdirectories within a parent
directory than it previously expected to based on the link count of
the parent, the resulting error message now gives the correct
directory name (previously an error message was issued but it
specified the wrong directory).

Savannah bug #16738: "find .... -exec ... {} +" now works if you have
a large environment and many files must be passed to the -exec
action.  The same problem affected the -execdir action, though since
the number of files in a given directory will normally be smaller, the
problem was worse for -exec.

Savannah bug #16579: Updatedb now works if it is running as a user
whose login shell is not actually a shell.

There have also been a number of documentation improvements (includng
Savannah bug #16269).

** Functional changes

For find, debug output can now be enabled at runtime with the -D
option.  This causes the printing of various sorts of information
about find's internal state and progress.

The find option -nowarn cannot itself produce a warning (this used to
happen with commands like "find . -name quux -nowarn -print".

** Performance Enhancements

Find now has a rudimentary cost-based optimiser.  It has an idea of
the basic cost of each test (i.e. that -name is very cheap while -size
is more expensive).  It re-orders tests bearing in mind the cost of
each test and its likely success.  Predicates with side effects (for
example -delete or -exec) are not reordered.  The optimiser is not
yet enabled by default, but the new option -O controls the query 
optimisation level.  To see this in action, try
  find -D opt -O3 . -type f -o -type c -o -size 555 -name Z
and compare the optimised query with:
  find -D opt -O3 . -size 555 -o -type c -o -type f -name Z
  find -D opt     . -size 555 -o -type c -o -type f -name Z

Over time, as optimisations are proven to be robust and correct, they
will be moved to lower optimisation levels.  Some optimisations have
always been performed by find (for example -name is always done early
if possible).
