* 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.

The description of -u was inaccurate when combined with -D:
$ printf '%s\n' '1 a' '2 a' | uniq -uD -f1
1 a
* doc/coreutils.texi (uniq invocation): Clarify that it's
the last repeated line that is suppressed from the output.
Fixes http://bugs.gnu.org/17022

* man/chmod.x: s/[+-=]/[-+=]/
* doc/perm.texi (Symbolic Modes): Likewise.
* THANKS.in: Remove patch owner.
Fixes http://bugs.gnu.org/17041
|
|
* 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.
Reported by Erik Bernstein in 739752@bugs.debian.org.
Fixes http://bugs.gnu.org/17010.

* gl/lib/fadvise.c: Use a pragma to turn off this warning option:
-Wsuggest-attribute=const. Without this change, building with
--enable-gcc-warnings would evoke this error:
lib/fadvise.c:25:1: error: function might be candidate for\
attribute 'const' [-Werror=suggest-attribute=const]

* scripts/autotools-install: Update version numbers of latest
automake and gettext packages.

- 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.

On most shells `:>file || framework_failure_` will not evaluate
the framework_failure_ even if there was an error writing the file.
shells which do evaluate the failure are ksh 93u+ and bash 4.2,
while shells wich don't include bash 4.3, solaris, freebsd, dash.
Furthermore this construct is problematic on Solaris 10 sh,
which will try to optimize away a `:' command in a loop
after the first iteration, even if it is redirected.
* tests/cp/link-deref.sh: Remove the leading colon on redirections.
* tests/cp/reflink-perm.sh: Likewise.
* tests/id/zero.sh: Likewise.

+ cfg.mk (sc_prohibit_colon_redirection): A new syntax check
to avoid further instances of this creeping in.

* tests/misc/nohup.sh: When running tests without a controlling tty,
an exec failure is triggered in a subshell, which causes POSIX
shells to immediately exit the subshell. This was brought
to notice by the newly conforming bash 4.3.
Fixes http:/bugs.gnu.org/16940

* 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.

* NEWS: Mention the fix.
* gnulib: Update to incorporate the fix.
This is the only change in this gnulib update.
* tests/misc/date.pl: Add a test for this case.

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

* 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.

|
* doc/coreutils.texi (dd invocation): Add an example for how to call
dd to save data from a failing disk. Mention GNU 'ddrescue' as one
of the more specialized tools in such a case.
|
|
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.
|
|
* doc/coreutils.texi: Prefer '@allowcodebreaks false' to '@w'.
Also, don't use @kbd except for keyboard input.
|
|
* 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.

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.

This should have been part of the previous commit v8.22-14-gf18999b
* po/POTFILES.in: Remove gnulib files no longer used.
Prompted by the continuous integration build failure at:
http://hydra.nixos.org/build/8288209/
|
|
* bootstrap.conf: Reference the used pipe-posix module
rather than the uneeded and larger spawn-pipe module,
which the pipe module is the deprecated equivalent of.
|
|
* 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.
|
|
* tests/cp/no-ctx.sh: Since the test diagnoses whether the
intercepted lgetfilecon() calls are actually called or not,
restrict the test to systems where that occurs.
The test cases are minimal on non SELinux systems and should
be well covered by other tests.
