* NEWS: Document the bug fix.
* src/od.c (skip): Call fseek even when n_skip is exactly the
same as the length of the current file. Otherwise, the next
iteration would use unadjusted input stream pointer, thus ignoring
the desired "skip". Report and patch by Paul GHALEB.

* src/copy.c (copy_reg): Read from a regular file, even if it
appears (stat.st_size == 0) to be empty. This reverts an
optimization introduced on 2005-11-23 for coreutils-6.0.
Otherwise, "cp /proc/cpuinfo /tmp" creates an empty file,
on e.g., linux-2.6.20.

manually appending to OPTIONAL_BIN_PROGS and MAN.
Move the code that adds "df" to the list of programs to build from
m4/jm-macros into this file.
Use gl_INCLUDE_EXCLUDE_PROG, then handle special cases: ginstall, [.

corresponding to "bin" programs. Add $(MAN) instead.

I wanted to use the xgetgroups function from id.c, so factored it out

Include "mgetgroups.h".
(print_group_list): Use mgetgroups, not xgetgroups.

Here's a patch along the lines of
<http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/10849/focus=10857>.
It's a bit large since it changes the test cases to match the behavior,
and the test cases' file names depend on the behavior!
* NEWS: pr -F no longer suppresses the footer or the first two blank
lines in the header.
* doc/coreutils.texi (pr invocation): Likewise. Also, a too-short
page length implies -t, not -T.
* src/pr.c (lines_per_header, lines_per_footer): Now constants.
(init_parameters): Don't try to change them.
(print_header): Use the same header and footer format regardless of
wither form feeds are being used.
(usage): Adjust to above change when describing too-short page length.
Too-short page length impliesy -t, not -T.
* tests/pr/2-S_f-t_notab: Adjust to the fact that -F now affects
only formfeed handling; it does not change the header.
* tests/pr/2-Sf-t_notab: Likewise.
...
* tests/pr/3-5l17f-t: Remove, since it's been renamed to another
file whose name has a line count 7 larger,
reflecting the new line count needed for this behavior.
* tests/pr/3a3l8f-t: Likewise.

--parents and symlinks. Close some race conditions possible when
the destination replaces a newly-created file with a symlink.
* NEWS: Document that 'cp --parents' no longer mishandles
symlinks in file name components of source.

(lchown) [!defined HAVE_LCHOWN]: Define to chown, for convenience.
* src/cp.c (lchown) [!HAVE_LCHOWN]: Likewise.
* src/install.c (lchown [!HAVE_LCHOWN]: Likewise.

* src/cp.c (re_protect): Likewise.
* src/install.c (change_attributes): Likewise.
* src/copy.c (copy_internal): Use ordinary C rather than an #if.
* src/cp.c (lchown) [!HAVE_LCHOWN]: Define to chown, for convenience.
(struct dir_attr): Cache the entire struct stat of the directory,
rather than just its mode, so that we needn't stat the directory
twice (which can lead to races).
(re_protect): Don't use XSTAT as that's not appropriate in
this context (symlinks should be followed here). Instead, use
the cached stat value.
(make_dir_parents_private): Save dir's entire struct stat, not
just its mode.
* tests/cp/cp-parents: Add test to check against bug with
cp --parents and symlinks.

* NEWS: "cp" no longer considers a destination symlink to be the
same as the referenced file when copying links or making backups.
* src/copy.c (copy_reg): When following a symlink, use the
followed name in later chown etc. requests, so that the created
file is affected, rather than the symlink. Use O_NOFOLLOW on
source when not dereferencing symlinks; this avoids a race.
Preserve errno correctly when doing multiple open attempts on the
destination.
(copy_internal): Follow destination symlinks only when copying a
regular file and only when we don't intend to remove or rename the
destination first, regardless of whether following source
symlinks; this is because since POSIX and tradition (e.g.,
FreeBSD) say we should ordinarily follow destination symlinks if
the system calls would ordinarily do so.
* src/copy.h (struct cp_options): Add comment that 'dereference'
is only for source files.
* src/cp.c (usage): Note that --derereference etc. are only for
source files.
(make_dir_parents_private): Follow symlinks, regardless of whether
--dereference is specified, because these are destination symlinks.
* tests/cp/same-file: Adjust tests to match revised behavior.
Filter out perror output since it might vary from host to host.
Use sed alone instead of also using echo.
* doc/coreutils.texi (cp invocation): Document the behavior better when
the destination is a symlink. Clarify source versus destination
symlinks. Describe the new behavior for destination symlinks.
2007-06-15 Jim Meyering <jim@meyering.net>
* src/copy.c: Include "canonicalize.h".
(copy_reg): Use canonicalize_filename_mode to follow the symlink,
so that we can always open with O_EXCL and avoid a race.
