Following are the before and after operations for seekable files,
for the various erroneous offsets handled by this patch:
skip beyond end of file
before: immediately exit(0);
after : immediately printf("cannot skip to specified offset"); exit(0);
skip > max file size
before: read whole file and exit(0);
after : immediately printf("cannot skip: Invalid argument"); exit(1);
seek > max file size
before: immediately printf("truncate error: EFBIG"); exit(1);
after : immediately printf("truncate error: EFBIG"); exit(1);
skip > OFF_T_MAX
before: read whole device/file and exit(0);
after : immediately printf("cannot skip:"); exit(1);
seek > OFF_T_MAX
before: immediately printf("truncate error: offset too large"); exit(1);
after : immediately printf("truncate error: offset too large"); exit(1);
skip > device size
before: read whole device and exit(0);
after : immediately printf("cannot skip: Invalid argument"); exit(1);
seek > device size
before: read whole device and printf("write error: ENOSPC"); exit(1);
after : immediately printf("cannot seek: Invalid argument"); exit(1);
* NEWS: Summarize this change in behavior.
* src/dd.c (skip): Add error checking for large seek/skip offsets on
seekable files, rather than deferring to using read() to advance offset.
(dd_copy): Print a warning if skip past EOF, as per FIXME comment.
* test/Makefile.am: Add 2 new tests.
* tests/dd/seek-skip-past-file: Add tests for first 3 cases above.
* tests/dd/seek-skip-past-dev: Add root only test for last case above.
* tests/dd/reblock: Change the IPC mechanism to the dd process
under test, from pipes to fifos. Also change the delay
between data writes to 0.2s for both tests.
This should increase the chance that the dd process
will read the data chunks separately.
* tests/test-lib.sh (Exit): New function by Ralf Wildenhues in automake
http://git.sv.gnu.org/gitweb/?p=automake.git;a=commitdiff;h=20594c08f63
* tests/**: Convert all uses:
This restrictive change converted the vast majority:
git grep -l '^(exit \$fail); exit \$fail$' \
| xargs perl -pi -e 's/'^\(exit \$fail\); exit \$fail$/Exit \$fail/'
And this did the rest, plus a few undesirable ones, so I manually
backed out the changes to ChangeLog-* and build-aux/check.mk:
git grep -l -E '\(exit [^)]+\); exit ' \
| xargs perl -pi -e 's/\(exit (.+?)\); exit \1/Exit $1/'
* src/dd.c (O_FULLBLOCK): Define using an enum, not #define.
Derive the value, rather than hard-coding to one that might conflict.
(usage): Mention iflag=fullblock in --help output.
(scanargs): Reset the O_FULLBLOCK bit, so that we don't try to set
an undefined attribute via fcntl (fd, F_SETFL, ...
* tests/dd/misc: Signal framework_failure when necessary.
Use "compare actual expected", so any diffs look "right".
* NEWS (dd): Alphabetize and reword.
* coreutils.texi (dd invocation): Adjust wording.
* src/dd.c (iread_fullblock): New function for reading full blocks.
(scanargs): Check for new parameter iflag=fullblock.
(skip): Use iread_fnc pointer instead of iread function.
(dd_copy): Use iread_fnc pointer instead of iread function.
* tests/dd/misc: Add test for dd - read full blocks.
* doc/coretuils.texi: Mention new parameter iflag=fullblock.
* NEWS: Mentioned the change.
* tests/check.mk (TESTS_ENVIRONMENT): Save and restore TMPDIR around
envvar-check, so that the few scripts that require $TMPDIR don't fail.
This is also good to let a user's default TMPDIR setting be used e.g.,
in the search for an 'other-partition'.
FIXME: this is pretty ugly. maybe undo it and find a better way.
(TESTS_ENVIRONMENT): Invoke perl scripts with $(PERL), and use -T
if the script requires that. Otherwise, use $(SHELL).
* tests/misc/md5sum-newline: Create a file whose name contains
a newline in Perl (resort to using "system", since open refuses).
Fix old brokenness exposed by this change:
* tests/du/files0-from: Correct test not to rely on stdin
being attached to a non-tty.
* tests/misc/sort (3g, 3h, 3i): Likewise: add explicit empty input file.
Avoid warnings about using qw()-around-commas.
* tests/rm/fail-eperm: Now that this test is run from a temporary
subdirectory, adjust the full name of the "rm" program we're going
to run.
Change #!/bin/sh to #!/usr/bin/perl, and factor out the few lines
of boilerplate code to invoke perl. Do not "require 5.00x";
a configure-time Perl test handles that

One side-effect of this change is that "make check" now works even if
you put "." early in your shell's search PATH (don't do that!).
Remove all test-related Makefile.am files, except those generated
by mk-script. Instead, tests/Makefile.am now lists not only the
tests directly under tests/, but also those in tests/*/ that are
not generated by mk-script, e.g., cp/abuse, cp/acl, mv/i-1, etc.
A lot of these changes are like this:
-. $srcdir/../lang-default
+. $top_srcdir/tests/lang-default
-. $srcdir/../test-lib.sh
+. $top_srcdir/tests/test-lib.sh
* configure.ac (AC_CONFIG_FILES): Remove corresponding Makefiles.
* tests/check.mk (vc_exe_in_TESTS): Relax syntax requirements.
* tests/rwx-to-mode: Remove file. Rewritten as...
* tests/test-lib.sh (rwx_to_mode_): ...this new function.
* tests/Makefile.am (EXTRA_DIST): Remove rwx-to-mode.
(SUBDIRS): Remove each dir with a removed Makefile.am.
(EXTRA_DIST): Add $(TESTS).
(TESTS): Add over 300 entries.
* lib/fd-reopen.c: Work even if FILE is "/dev/stdin".
Problem reported by Geoffrey Lee in <http://bugs.debian.org/290727>.
* tests/dd/misc: Check for this bug.
* src/mktemp.c: Update copyright to use newer form.
Make first copyright lines consistent. Some did not end in ", Inc.".
Due to that missing ", Inc" at end of line, emacs' copyright-updating
code missed some opportunities. This corrects most of those, and
adds some mistakenly omitted years.
* src/chown-core.c: Adjust.
* src/chown-core.h: Likewise.
* src/copy.c: Likewise.
* src/copy.h: Likewise.
* src/cp-hash.c: Likewise.
* src/cp.c: Likewise.
* src/group-list.h: Likewise.
* src/mktemp.c: Likewise.
* src/stat.c: Likewise.
* tests/chmod/equal-x: Likewise.
* tests/dd/skip-seek: Likewise.
* tests/envvar-check: Likewise.
* tests/mv/into-self-2: Likewise.
* tests/rm/Makefile.am (TESTS): Add empty-name and unreadable.
* tests/rm/empty-name: Likewise.
* tests/rm/unreadable: Reenable this test. Adjust for new rm.
* tests/mkdir/Makefile.am: Add writable-under-readonly.
* tests/mkdir/writable-under-readonly: Add some comments.
This test is always skipped, for now.
* tests/Makefile.am (ta): Hook up the new root-only script.
* tests/tail-2/infloop-1: Make this test pass.
* tests/tail-2/Makefile.am (TESTS): Add infloop-1.
* tests/tail-2/fflush: Remove unused file.
* tests/check.mk (vc_executable_is_in_TESTS): More portable.
* tests/check.mk (check): Depend on the above.
* build-aux/check.mk: Remove comment mentioning AUTHORS file.
tests/check.mk (top_srcdir): Define.
tests/*/Makefile.am: Remove definitions of $(srcdir), $(top_srcdir),
$(abs_top_srcdir), and $(abs_top_builddir), since they're
defined via the included tests/check.mk.
* tests/CuTmpdir.pm: New file.
* tests/Makefile.am (EXTRA_DIST): Add CuTmpdir.pm.
* tests/misc/od, tests/misc/base64, tests/misc/basename:
* tests/misc/cut, tests/misc/date, tests/misc/dirname:
* tests/misc/expand, tests/misc/fold, tests/misc/head-elide-tail:

* tests/dd/skip-seek, tests/dircolors/simple, tests/du/files0-from:

* tests/seq/basic, tests/sha1sum/basic-1, tests/sha1sum/sample-vec:
* tests/sum/basic-1, tests/tsort/basic-1, tests/unexpand/basic-1:
* tests/mv/i-1, tests/rm/empty-name, tests/rm/unreadable: Use it.
* tests/misc/test-diag: Use "$ENV{abs_top_builddir}/src/test",
not "../../src/test", so it works when run from a subdirectory.
* tests/ls-2/tests: Create temp files and dirs from within the perl
script, so that they're removed, when run from a subdirectory.
* doc/coreutils.texi (dd invocation): Warn that noatime might not be
reliable.
* src/dd.c (flags, usage): Look at O_NOATIME, not
HAVE_WORKING_O_NOATIME, to decide whether to support the noatime
flag, so that dd attempts O_NOATIME even if the build file system
does not support it. Problem reported by Jim Meyering today in
bug-coreutils.
* tests/dd/misc: Generate a warning, not a failure, if noatime
exists but fails.
* Transform all Makefile.am files so that when running "make check",
CU_TEST_NAME is set to the name of the test. This is so that when I
run valgrind-enabled (--log-file-qualifier=CU_TEST_NAME) "make check"
on the entire package it is more convenient to map a leak or error
found in a valgrind log file back to the offending test.
Use this command:
(echo tests/Makefile.am.in; find tests -name Makefile.am) \
|xargs perl -pi -e '/^(\s*)PATH=...VG_PATH_PREFIX/ and ' \
-e 'print $1,q|CU_TEST_NAME=`basename $(abs_srcdir)`,$$tst |,"\\\n"'
as POSIX requires.
* src/dd.c (scanargs): Implement it.
* tests/dd/misc (outbytes): Test it.
* doc/coreutils.texi (dd invocation): Specify that bs=N
overrides later ibs and obs, undoing part of the
previous change. (The behavior was wrong.)
Remove from CVS, since ./bootstrap generates them automatically.
* .cvsignore: Add INSTALL, Makefile.in, *.cache, *.lineno, *.log.
Remove more-specific entries. This catches files like configure.lineno.
* man/.cvsignore: Add Makefile.in.
* src/.cvsignore: Add Makefile.in.
Remove .version, dir.c, install, mvdir, stamp-v, vdir.c, version.c.
For .cvsignore file under the tests directory:
Add Makefile.in. Sort entries if necessary. Remove *.I, *.E,
*.X, *.O, *-tests, build-script, mk-script if they're never
created in this directory.
* build-aux/.cvsignore: New file.
* doc/.cvsignore: Add Makefile.in, coreutils.html, coreutils.pdf,
coreutils.ps, coreutils.tps. Remove coreutils.cm (dunno what it
is, but the makefile doesn't mention it). Remove coreutils.info
as it is subsumed by coreutils.info*.
* lib/.cvsignore: Add Makefile.in, getdate.tab.h.
Remove stat.c, sysexit.h.
* m4/.cvsignore: Remove Makefile, dev-ino.m4, glibc2.m4, intdiv0.m4,
inttypes-h.m4, inttypes-pri.m4, jm-glibc-io.m4, lcmessage.m4,
lock.m4, printf-posix.m4, same-inode.m4, size_max.m4,
uintmax_t.m4, ulonglong.m4, visibility.m4, xsize.m4. Many of
these are put in automatically by ../bootstrap, but that's a
bootstrap bug that I plan to fix shortly.
* po/.cvsignore: More ../bootstrap-related fixes, plus remove old
cruft. Add *.po, LINGUAS, Makevars. Remove *.cat, *.msg,
cat-id-dbl.c, messages.mo, stamp-cat-id.
(set -x when VERBOSE=yes) when stderr is redirected before stdout
causing shell tracing of the stdout redirection to be written to
the stderr file. Avoid problem and test failure on HP-UX by
redirecting stderr last.
* tests/dd/unblock-sync: Order shell file redirections for
stderr and stdout in the common style.
tests/acl: Likewise.
