* src/df.c (alloc_table_row): Use the size of char** to enlarge
the table. Spotted by Coverity.
|
|
* src/ln.c (do_link): It's not obvious that record_file() is a noop
in the symlink case (in that case dest_set is NULL and so ignored).
So to make it obvious, and to avoid false positives seen in coverity,
add the explicit condition here.
|
|
* NEWS: Fix a confusing old entry.
* cfg.mk (old_NEWS_hash): Adjust accordingly.
* src/cp.c (usage): Separate the -Z and --context descriptions.
* src/install.c: Likewise.
* src/mkdir.c: Likewise.
* src/mkfifo.c: Likewise.
* src/mknod.c: Likewise.
Fixes http://bugs.gnu.org/17220

* tests/misc/numfmt.pl: Fix comment misspelling.
* src/cut.c: Likewise.
* src/tsort.c (detect_loop): Replace an fprintf() with error().
|
|
* doc/coreutils.texi (shred invocation): Mention some reasons
why clearing slack space might be useful.
* src/shred.c (do_wipefd): Add initial writes for each pass
for small regular files in case the storage for those is
in the inode, and thus a larger write up to a block size would
bypass that. Move the direct I/O control to...
(dopass): ... here so we can avoid enabling it for these small
initial writes. It's better to retry direct I/O for each pass
anyway to handle the case where direct I/O is disabled for only
the last portion of a file when the size is not a multiple of
the block size. Note we don't avoid the sync for the initial
write as it will be small but more importantly could be on a
different part of the disk and so worth doing independently
to ensure the write is not discarded.
* tests/misc/shred-exact.sh: Check some more direct I/O cases.
* NEWS: Mention the improvements.
The inode storage issue was mentioned by Paul Eggert.
|
|
* src/shred.c (do_wipefd): Don't increase the size written
for an empty file up to a full block. Also increase the size
to OFF_T_MAX in the edge case where we do overflow.
* NEWS: Mention the shred improvements from recent changes.
* tests/misc/shred-passes.sh: Adjust as we no longer
write a BLKSIZE of data for empty files.
|
|
* src/copy.c (copy_internal): Replace dev_t arg DEVICE with struct
stat pointer arg PARENT. All callers changed. This removes an
unwarranted assumption that dev_t values of 0 cannot occur in file
systems. See: http://bugs.gnu.org/17179
|
|
* src/shred.c (do_wipefd): Shred one block of empty regular files.
This reverts an unintended part of the previous change.
|
|
See: http://bugs.gnu.org/17149
* src/shred.c [__linux__]: Include <sys/mtio.h>.
(dorewind): New function, which works around the lseek problem with
tape drives on GNU/Linux, the same way that dd does.
(dopass): Use it. New arg ST, needed for dorewind. All uses changed.
(do_wipefd): Don't rely on undefined behavior on integer overflow
of file sizes. Use INT_ADD_OVERFLOW instead.
|
|
This removes an unportable assumption that if lseek succeeds, the
file is capable of seeking. See: http://bugs.gnu.org/17145
* src/head.c (elseek): New function, for consistency in reporting
lseek failures.
(elide_tail_bytes_file, elide_tail_lines_seekable)
(elide_tail_lines_file, head_lines, head): Use it.
(elide_tail_bytes_file, elide_tail_lines_file):
New args CURRENT_POS and SIZE. All uses changed. Don't bother
invoking lseek, since we know the file's pos and size now.
(elide_tail_bytes_file): Change a local from uintmax_t to off_t,
since it fits.
(head): Use lseek only on regular files, since its behavior on
unseekable devices is implementation-defined.
* NEWS: Document this.
|
|
* src/head.c (elide_tail_bytes_file): Fix typo in lseek invocation.
* tests/misc/head-c.sh: Add test for this bug.
* NEWS: Document this.
|
|
* src/copy.c (overwrite_ok): Fix the gettext calls so
that the second string is tagged for translation.
Display the correct "replace ..." prompt when in move_mode.
* tests/mv/i-3.sh: Display the output on failure to ease debugging.
|
|
* src/ptx.c (main): Add a 'break' after the --format handling case.
Otherwise it would fall through into the usage case.
* tests/misc/ptx.pl: Add test cases for --format=tex and --format=roff.
* NEWS (Bug fixes): Mention the fix.
Bug introduced in 1999-04-04 commit, SH-UTILS-1_16f-269-gd815c15.
Spotted by coverity (MISSING_BREAK).
|
|
* src/basename.c (usage): Mention that -s implies -a.
(main): Add "fall through" comment to case 's'.
Spotted by coverity: MISSING_BREAK.
|
|
* src/copy.c (overwrite_ok): Rename from overwrite_prompt. Invoke
yesno instead of having the caller do it; that's cleaner. Return
bool, not void. All callers changed.
|
|
* src/copy.c (overwrite_prompt): New arg X. All callers changed.
Use X to improve the quality of the prompt (Bug#17087).
* tests/mv/i-2.sh, tests/mv/i-3.sh: Change test to match new prompt.
|

Input buffering is best avoided because it introduces
delayed processing of output for intermittent input,
especially when the output size is less than that of
the input buffer. This is significant when output
is being further processed which could happen if split
is writing to precreated fifos, or through --filter.
If input is arriving quickly from a pipe then this will
already be buffered before we read it, so fast arriving
input shouldn't be a performance issue.
* src/split.c (lines_split, lines_bytes_split, bytes_split,
lines_chunk_split, bytes_chunk_extract): s/full_read/safe_read/.
* THANKS.in: Mention the reporter.
* NEWS: Mention the improvement.
|
|
* src/chroot.c (setgroups): Change this replacement to
fail when called so that platforms like Interix without support for
supplemental groups don't silently ignore a --groups option.
|
|
For files with "special" bits set, we would stat the relative
file name in the wrong directory, giving an erroneous ENOENT diagnostic.
This issue was introduced with commit v5.92-653-gc1994c1
which changed fts to not change directory on traversal.
* src/chmod.c (mode_changed): Use fts->fts_cwd_fd with fstatat rather
than stat. All callers changed.
* tests/chmod/c-option.sh: Add a test case.
* NEWS: Mention the fix.

Problem reported by Rich Burridge.
* src/stat.c [HAVE_GETATTRAT]: Include <attr.h>, <sys/nvpair.h>.
(print_statfs, print_stat, print_it):
Pass fd, too, for the benefit of get_birthtime.
All uses changed.
(get_birthtime): New function, for porting to Solaris 11.
(print_stat): Use it.
* configure.ac (getattrat, LIB_NVPAIR): New checks.
* src/local.mk (src_stat_LDADD): Add $(LIB_NVPAIR).
|

Prior to this change, "ln -sr '' F" would segfault, attempting
to read path2[1] in relpath.c's path_common_prefix function.
This problem arises whenever canonicalize_filename_mode returns
NULL.
* src/ln.c (convert_abs_rel): Call relpath only when
both canonicalize_filename_mode calls return non-NULL.
* tests/ln/relative.sh: Add a test to trigger this failure.
* THANKS.in: List reporter's name/address.
* NEWS (Bug fixes): Mention it.

- Support arbitrary numbers in --groups, consistent with
what is already done for --userspec
- Avoid look-ups entirely for --groups items with a leading '+'
- Support names that are actually numbers in --groups
- Ignore an empty --groups="" option for consistency with --userspec
- Look up both inside and outside the chroot with inside taking
precedence. The look-up outside may load required libraries
to complete the look-up inside the chroot. This can happen for
example with a 32 bit chroot on a 64 bit system, where the
32 bit NSS plugins within the chroot fail to load.
* src/chroot.c (parse_additional_groups): A new function refactored
from set_addition_groups(), to just do the parsing. The actual
setgroups() call is separated out for calling from the chroot later.
(main): Call parse_user_spec() and parse_additional_groups()
both outside and inside the chroot for the reasons outlined above.
* tests/misc/chroot-credentials.sh: Ensure arbitrary numeric IDs
can be specified without causing look-up errors.
* NEWS: Mention the improvements.
* THANKS.in: Add Norihiro Kamae who initially reported the issue
with a proposed patch.
Also thanks to Dmitry V. Levin for his diagnosis and sample patch.

* src/df.c (usage): Adjust the --human and --si descriptions
to not depend on each other. Also include an example that is
illustrative of the rounding, suffix, width, and localized fractions.
* src/system.h (emit_size_note). Adjust so that it's obvious the
description is pertaining to the input SIZE argument, and not
to any sizes that might be output by df for example.
Fixes http://bugs.gnu.org/16922

* src/copy.c (copy_dir): Use the new SAVEDIR_SORT_FASTREAD, not
SAVEDIR_SORT_INODE. Problem reported by Bernhard Voelker in:

* src/copy.c (copy_dir): Adjust to recent gnulib change.
|
|
* src/shuf.c (main): s/No/no/, introduced by commit v8.22-25-g9f60f37.
* NEWS: Also adjust the NEWS for that recent commit to make it
clear this was new bug rather than a regression.
Prompted by the syntax-check rule sc_error_message_uppercase

Problem reported by valiant xiao in <http://bugs.gnu.org/16855>.
* NEWS: Document this.
* src/shuf.c (main): With -r, report an error if the input is empty.
* tests/misc/shuf.sh: Test for the bug.
|
|
* src/copy.c (copy_reg): If linkat() is available it doesn't
matter about the gnulib emulation provided, and thus the
LINK_FOLLOWS_SYMLINKS should not have significance here.
This was noticed on FreeBSD and the consequence is that
cp --link will create hardlinks to symlinks there, rather
than emulating with symlinks to symlinks.
* tests/cp/link-deref.sh: Adjust the checks to cater
for all cases where hardlinks to symlinks are supported.

If we can't output more data, we should immediately
diagnose the issue and exit rather than consuming all
of input (in some cases).
* src/tail.c (xwrite_stdout): Also diagnose the case where
only some data is written. Also clearerr() to avoid the
redundant less specific error from atexit (close_stdout);
* src/head.c (xwrite_stdout): Copy this new function from tail,
and use it to write all output.
* tests/misc/head-write-error.sh: A new test to ensure we
exit immediately on write error.
* tests/local.mk: Reference the new test.
|
|
* src/head.c (elide_tail_lines_pipe): Just output all input in
this case to avoid the issue and also avoid redundant '\n' processing.
(elide_tail_lines_seekable): Likewise.
* tests/misc/head-elide-tail.pl: Add tests for no '\n' at EOF.
* NEWS: Mention the fix.

* src/od.c (main): Handle the new --endian option,
taking "little" and "big" as parameters.
(usage): Describe the new option.
(PRINT_FIELDS): Adjust to swap bytes if required.
* tests/misc/od-endian.sh: A new test to verify
the byte swapping operations for hex (ints) and floats
for all sizes between 1 and 16 inclusive.
* test/local.mk: Reference the new test.
* doc/coreutils.texi (od invocation): Describe the new option.
* NEWS: Mention the new feature.
|
|
* src/stat.c (human_fstype): Add new file system ID definitions.
* NEWS: Mention the improvement.
Fixes http://bugs.gnu.org/16336
|
|
* src/ls.c: Remove all mention of SELinux since ls
should treat all security context labels equally.
* doc/coreutils.texi (ls invocation): Likewise.
(id invocation): Clarify that -Z outputs the context
inherited by the process, rather than one specific to a user.
Note for SMACK this can be set instead by the SMACK64EXEC label,
in the unusual case where this is set on the id executable.
* src/id.c (usage): Likewise.
* src/mkdir.c (usage): Clarify that -Z is specific to SELinux,
while --context=CTX is also supported for SMACK.
* src/mkfifo.c (usage): Likewise.
* src/mknod.c (usage): Likewise.
|
|
* src/ln.c (errno_nonexisting): A new function to determine if
the errno implies that a file doesn't or can't (currently) exist.
(target_directory_operand): Use the new function to expand the
set of errors we handle.
* tests/ln/sf-1.sh: Add test cases for the newly handled errors.
* THANKS.in: Mention the reporter.
* NEWS: Mention the bug fix.
|
|
* src/selinux.c (restorecon_private): On ArchLinux the
`fakeroot cp -a file1 file2` command segfaulted due
to getfscreatecon() returning a NULL context.
So map this to the sometimes ignored ENODATA error,
rather than crashing.
* tests/cp/no-ctx.sh: Add a new test case.
* tests/local.mk: Reference the new test.
* NEWS: Mention the fix.
Fixes http://bugs.gnu.org/16335

|
* src/copy.c (copy_internal): Use the global process context
to set the context of existing directories before they're populated.
This is more consistent with the new directory case, and fixes
a bug for existing directories where we erroneously set the
context to the last copied descendent, rather than to that of
the source directory itself.
* tests/cp/cp-a-selinux.sh: Add a test for this case.
* NEWS: Mention the fix.
* THANKS.in: Add reporter Michal Trunecka.
|
|
* src/selinux.c: As the copyright is assigned to the FSF for all
of coreutils, replace the copyright holder from "Red Hat, Inc."
to "Free Software Foundation, Inc.". Prompted by a warning of
'make update-copyright'. Also update the copyright year.
|
|
Run "make update-copyright", but then also run this,
perl -pi -e 's/2\d\d\d-//' tests/sample-test
to make that one script use the single most recent year number.

hostfs is provided by the Linux UML subsystem.
smackfs is provided by the Linux Smack security module.
* src/stat.c (human_fstype): Add new file system ID definitions.
* NEWS: Mention the improvement, and adjust for the fact that
SNFS is a remote file system.
|
|
* src/tail.c: With inotify, when a file is initially absent,
we fstat(-1) for that file spec, thus recording an errnum of EBADF,
which caused the "has become accessible" diagnostic to be issued,
when the file first appears. Instead we avoid the fstat(-1) and
thus emit the more natural and consistent "has appeared" diagnostic.
* tests/tail-2/retry.sh: Use the new diagnostic which also causes
this test to pass on systems without inotify.
|
|
Original problem reported by Philipp Thomas in
<http://bugs.gnu.org/16061>.
* NEWS: shuf --repeat, not shuf --repetitions.
* doc/coreutils.texi (shuf invocation):
* src/shuf.c (usage, long_opts, main):
* tests/misc/shuf.sh:
Likewise. Also, the default head-count is infinity.
|
|
* src/selinux.h (ignorable_ctx_err): A new function used
to determine if a warning should be given after a call
to defaultcon() or restorecon().
* src/cp.c (main): Fix the setfscreatecon() call to use
the argument passed by the user.
* src/mkdir.c (make_ancestor): Show all but "ignoreable" errors
from defaultcon() and restorecon().
* tests/misc/selinux.sh: Add a test run as root in selinux enforcing
mode, to ensure cp --context=invalid is honored and fails immediately.

libcrypto is generally available and has well optimized
crypto hash routines particular to various systems.
For example, testing sha1sum with openssl-1.0.0j
on an i3-2310M, gives a performance boost of about 40%:
$ time sha1sum.old --tag ~/test.iso
SHA1 (/home/padraig/test.iso) = 3c27f7ed01965fd2b89e22128fd62dc51a3bef30
real 0m4.692s
user 0m4.499s
sys 0m0.162s
$ time sha1sum.new --tag ~/test.iso
SHA1 (/home/padraig/test.iso) = 3c27f7ed01965fd2b89e22128fd62dc51a3bef30
real 0m2.685s
user 0m2.512s
sys 0m0.170s
* configure.ac: By default, enable use of libcrypto if available.
* src/local.mk: Link with libcrypto.
* NEWS: Mention the md5sum and sha*sum improvements.

* src/df.c (get_disk): Use the same heuristic used in
get_point() to select the shortest file system mount point,
in an attempt to show the base mounted file system.
* NEWS: Mention the bug fix.

This is so the matching for the device is done on the canonical name
of the disk node, rather than on the path of the symlink.
In any case the user will generally want to use the symlink target.
* src/df.c (get_disk): Canonicalize the passed file,
before matching against the list of mounted file system devices.
Note we pass the original symlink name to the "file" output field,
as the symlink target is usually available through the "source" field.
* tests/df/df-symlink.sh: Test the dereferencing operation.
* tests/local.mk: Mention the new test.
* NEWS: Mention the fix.

Add a new rule to ensure the use of quote() instead of '%s' or `%s'
in format strings of diagnostics messages.
* cfg.mk (sc_prohibit_quotes_notation): Add rule.
* TODO: Remove the entry regarding the '%s' notation.
* src/mkfifo.c (main): Remove the offending and in this case even
duplicate quoting in the format string of the error diagnostic.
* src/mknod.c (main): Likewise.
* src/df.c (decode_output_arg): Change two invocations of error()
according to the above new rule.
* src/numfmt.c: Fix numerous wrong quote notations to fit the above
new rule, mostly in internal debugging diagnostic messages.
|
|
* src/longlong.h: Sync with the latest longlong.h from libgmp to:
- avoid arm asm when being compiled for the thumb instruction [sub]set
- avoid old powerpc assembly that is incompatible with newer GCC
- add arm64 optimized count_trailing_zeros()
- add sparc64 optimized add_ssaaaa() and umul_ppmm()
|

* src/extent-scan.c (extent_need_sync): Remove the FIXME comment about
removing the work around. As discussed in [1], the needed FIEMAP fix
never made it into the Linux kernel.
* src/realpath.c (longopts): Remove the FIXME comment about deprecating
the --strip option as it's a valid alias for --no-symlinks option.
Also discussed in [1].
