* src/md5sum.c: Use the same file name escaping method used
when generating and checking checksums. I.E. ensure a single line
per file by starting the line with '\' for any file name containing '\n'
and replacing those with "\\n".
* NEWS: Move the item from changes in behavior to improvements,
since this is no longer a backwards incompat change when
processing stdout status messages.
* tests/misc/md5sum.pl: Remove quotes from expected status output.
* tests/misc/sha1sum.pl: Likewise.
|
|
* src/date.c (main): Use %:z rather than %z with --iso-8601
as the standard states to consistently use extended format.
Note either format can be parsed by date.
* tests/misc/date.pl: Adjust accordingly.
* doc/coreutils.texi (du invocation): Clarify that "iso"
time styles are only similar to ISO-8601.
(ls invocation): Likewise.
(date invocation): Adjust the comment stating
that only --rfc-3339 output can be parsed by date(1).
* NEWS: Mention the change in behavior.

These strings are often file names or other user specified
parameters, which can give confusing errors in
the presence of unexpected characters for example.
* cfg.mk (sc_error_quotes): A new syntax check rule.
* src/*.c: Wrap error() string arguments with quote().
* tests/: Adjust accordingly.
* NEWS: Mention the improvement.
|
|
This is especially significant when using --check
with files generated on a windows system, where the \r
characters produce corrupted and confusing error messages.
This also ensures status messages are output on a single line.
* src/md5sum.c: Use quote() for printed file names.
* tests/misc/md5sum.pl: Adjust accordingly.
* NEWS: Mention the change in behavior.

a separator when calculating max_idx.
* tests/ls/w-option.sh: Add a test case.
* NEWS: Mention the bug fix.
|
|
* src/ls.c (print_with_separator): Renamed from print_with_commas,
and parameterized to accept the separator to print.
Also fix an edge case where '\n' not printed when
the POS variable overflows SIZE_MAX.
(print_current_files): Degenerate -x and -C to using the
cheaper print_with_separator() in the -w0 case.
* doc/coreutils.texi (ls invocation): Document the new feature.
* tests/ls/w-option.sh: A new test.
* tests/local.mk: Reference the new test.

* src/dircolors.c (dc_parse_stream): Support globbing of
TERM entries, to allow entries like "TERM *256color*" for example.
* src/dircolors.hin: Reduce the internal list with globbing.
* tests/misc/dircolors.pl: New test cases.
* NEWS: Mention the improvement.

In the presence of bind mounts of a device, the 4th "mount root" field
from /proc/self/mountinfo is now considered, so as to prefer mount
points closer to the root of the device. Note on older systems with
an /etc/mtab file, the source device was listed as the originating
directory, and so this was not an issue.
Details at http://pad.lv/1432871
* src/df.c (filter_mount_list): When deduplicating mount entries,
only prefer sources nearer or at the root of the device, when the
target is nearer the root of the device.
* NEWS: Mention the change in behavior.

du calls stat for each mount point at startup. This would block or
even make du fail if stat for an unrelated mount point hangs.
The result is not needed in the normal case anyway and therefore
should be avoided. Issue introduced in commit v8.19-2-gcf7e1b5.
* src/du.c (fill_mount_table): Move function up as it's not used ...
(mount_point_in_fts_cycle): ... here, i.e., the DI_MNT set is
initialized and filled only iff FTS has detected a directory cycle.
(main): Remove the initialization and filling of the DI_MNT set here,
and free the DI_MNT set only if it was used.
|
|
* src/base64.c (main): Support decimal numbers with leading zeros,
by disabling the auto detection of octal and hex. It's not
envisaged that base conversion is needed for --wrap parameters,
and in the edge case it is, $((0x0)) shell constructs can be used.
* tests/misc/base64.pl: Adjust accordingly.
* NEWS: Mention the change in behavior.

SUMMARY: AddressSanitizer: global-buffer-overflow src/shred.c:782
* src/shred.c (gen_patterns): Restrict pattern selection
to the K available, which regressed due to v5.92-1462-g65533e1.
* tests/misc/shred-passes.sh: Add a deterministic test case.

* src/factor.c (n_out): A new global variable to track
how much data has been written to stdout.
(print_factors_single): Use n_out to determine whether
to flush the current (and previous) lines.
* tests/misc/factor-parallel.sh: Add a new test.
* tests/local.mk: Reference the new test.
* NEWS: Mention the bug fix.
|
|
* src/numfmt.c (simple_strtod_int): Don't count leading zeros
as significant digits. Also have leading zeros as optional
for floating point numbers.
* tests/misc/numfmt.pl: Add test cases.
* NEWS: Mention the fix.
|
|
Due to existing limits this is usually triggered
with an increased precision. We also add further
restrictions to the output of increased precision numbers.
* src/numfmt.c (simple_round): Avoid intmax_t overflow.
(simple_strtod_int): Count digits consistently
for precision loss and overflow detection.
(prepare_padded_number): Include the precision
when excluding numbers to output, since the precision
determines the ultimate values used in the rounding scheme
in double_to_human().
* tests/misc/numfmt.pl: Add previously failing test cases.
* NEWS: Mention the fix.
|
|
* src/numfmt.c (usage): Update the --format description
to indicate precision is allowed.
(parse_format_string): Parse a precision specification
like the standard printf does.
(double_to_human): Honor the precision in --to mode.
* tests/misc/numfmt.pl: New tests.
* doc/coreutils.texi (numfmt invocation): Mention the new feature.
* NEWS: Likewise.
|
|
* src/numfmt.c: Replace field handling code with logic that understands
field range specifiers. Instead of processing a single field and
printing line prefix/suffix around it, process each field in the line
checking whether it has been included for conversion. If so convert and
print, otherwise just print the unaltered field.
(extract_fields): Removed.
(skip_fields): Removed.
(process_line): Gutted and heavily reworked.
(process_suffixed_number): FIELD is now passed as an arg instead of
using a global.
(parse_field_arg): New function that parses field range specifiers.
(next_field): New function that returns pointers to the next field in
a line.
(process_field): New function that wraps the field conversion logic
(include_field): New function that checks whether a field should be
converted
(compare_field): New function used for field value comparisons in a
gl_list.
(free_field): New function used for freeing field values in a gl_list.
Global variable FIELD removed.
New global variable all_fields indicates whether all fields should be
processed.
New global variable all_fields_after stores the first field of a N-
style range.
New global variable all_fields_before stores the last field of a -M
style range.
New global variable field_list stores explicitly specified fields to
process (N N,M or N-M style specifiers).
(usage): Document newly supported field range specifiers.
* bootstrap.conf: Include xlist and linked-list modules. numfmt now
uses the gl_linked_list implementation to store the field ranges.
* tests/misc/numfmt.pl: Add tests for 'cut style' field ranges.
Adjust existing tests as partial output can occur before an error
Remove test for the 'invalid' field -5.. this is now a valid range.
* gnulib: update to avoid compiler warnings in linked-list.
* NEWS: Mention the new feature.
|
|
* src/numfmt.c (unit_to_umax): Support SI (power of 10) suffixes
with the --from-unit and --to-unit options. Treat suffixes like
is done with --from=auto, which for example will change the meaning
of --to-unit=G to that of --to-unit=Gi. The suffix support was
previously undocumented and it's better to avoid the traditional
coreutils suffix handling in numfmt by default.
* doc/coreutils.texi: Document the new behavior. Also fix a typo
mentioning {from,to}=units=.
* tests/misc/numfmt.pl: Adjust accordingly.
* NEWS: Mention the change in behavior.
|
|
* src/tail.c (tail_forever_inotify): Use the fspec pointer to
distinguish previously output files, rather than a descriptor
from the inotify event. That event descriptor was that of
the parent directory when files were created or renamed etc.
(check_fspec): Adjust for the new comparison. Also show the
header when the file is truncated, since we show data
in this case also.
* tests/tail-2/F-headers.sh: A new test case.
* tests/local.mk: Reference the new test.
* NEWS: Mention the bug fix.
|

When the parent directory exists and has a different
default context to the final directory, the context
was incorrectly left as that of the parent directory.
* src/mkdir.c (process_dir): Because defaultcon() is called for
existing ancestors (as it must be to avoid races), then we must
unconditionally call restorecon() on the last component due to
the already documented caveat with make_dir_parents().
Alternatively you could temp disable o->set_security_context
around make_dir_parents(), but that would be subject to races.
* tests (tests/mkdir/restorecon.sh): Add a TODO for improvement.
Reference mknod and mkfifo with print_ver_.
* NEWS: Mention the bug fix.

* src/timeout.c (cleanup): Don't send SIGCONT to the monitored program
when --foreground is specified, as it's generally not needed for
foreground programs, and can cause intermittent signal delivery
issues with monitors like GDB for example.
* doc/coreutils.texi (timeout invocation): Mention that SIGCONT
is not sent with --foreground.
* NEWS: Mention the behavior change.

Generally if logs are truncated, they're truncated to 0 length,
so output all existing data when our heuristic determines truncation.
Note with inotify, truncate() and write() are often determined
independently and so all data would be written if that was the case.
* src/tail.c (check_fspec): Reset file offset to 0 upon truncation.
(tail_forever): Likewise.
(recheck): Add a FIXME for the related issue where tail may lose
data due to tail discounting older log files too early.
* tests/tail-2/truncate.sh: A new test.
* tests/local.mk: Reference the new test.
* NEWS: Mention the fix.

The previous fixes to races in the various tail tests,
identified actual races in the tail inotify implementation.
With --follow=descriptor, if the tailed file was replaced before
the inotify watch was added, then any subsequent changes were ignored.
Similarly in --follow=name mode, all changes to a new name were
effectively ignored if that name was created after the original open()
but before the inotify_add_watch().
* src/tail.c (tail_forever_inotify): Fix 3 cases.
1. With -f, don't stop tailing when file removed before watch.
2. With -f, watch right file when file replaced before watch.
3. With -F, inspect correct file when replaced before watch.
Existing tests identify these when tail compiled with TAIL_TEST_SLEEP.
* tests/tail-2/inotify-rotate-resources.sh:
This test also identifies the issue with --follow=name
when TAIL_TEST_SLEEP is used. Adjust so the test is immune
to such races, and also fail quicker on remote file systems.
* tests/tail-2/inotify-race2.sh: A new test using GDB,
based on inotify-race.sh, which tests the -F race
without needed recompilation with sleeps.
* tests/local.mk: Reference the new test.
* NEWS: Mention the bug.

* src/df.c (filter_mount_list): With -l, avoid stating remote mounts.
* init.cfg: Avoid test hangs with inaccessible remote mounts.
* tests/df/no-mtab-status.sh: Skip with inaccessible remote mounts.
* tests/df/skip-rootfs.sh: Likewise.
* tests/df/total-verify.sh: Likewise.
* NEWS: Mention the bug fix.

* src/tail.c (tail_forever_inotify): Only monitor write()s and
truncate()s to files in --follow=descriptor mode, thus avoiding
the bug where we removed the watch on renamed files.
Also adjust the inotify event processing code that is
now significant only in --follow=name mode.
* tests/tail-2/F-vs-rename.sh: Improve this existing test by running
in both polling and inotify modes.
* tests/tail-2/f-vs-rename.sh: A new test based on the existing one.
* tests/local.mk: Reference the new test.

Using a test file generated with:
yes | head -n100M > 2x100M.txt
before> time wc -l 2x100M.txt
real 0.842s
user 0.810s
sys 0.033s
after> time wc -l 2x100M.txt
real 0.142s
user 0.111s
sys 0.031s
* src/wc.c (wc): Split the loop that deals with -l into 3.
The first is used at the start of the input to determine if
the average line length is < 15, and if so the second loop is
used to look for '\n' internally to wc. For longer lines,
memchr is used as before to take advantage of system specific
optimizations which any outweigh function call overhead.
Note the first 2 loops could be combined, though in testing,
GCC 4.9.2 at least, wasn't sophisticated enough to separate
the loops based on the "check_len" invariant.
Note also __builtin_memchr() isn't significant here as
GCC currently only applies constant folding with that.
* NEWS: Mention the improvement.

Adjust commit v8.23-140-gfdd6ebf to add the --output-error option
instead of --write-error, and treat open() errors like write() errors.
* doc/coreutils.texi (tee invocation): s/write-error/output-error/.
* src/tee.c (main): Exit on open() error if appropriate.
* tests/misc/tee.sh: Add a case to test open() errors.
* NEWS: Adjust for the more general output error behavior.

Note that IBRIX used to have a different magic number 0x013111A7
instead of the current 0x013111A8. However, the former is no longer
used and the version of IBRIX it was used in is really ancient, so
it's extremely unlikely anyone is still using it. Therefore, just
add the newer magic number.
Mark IBRIX as a 'remote' file system type as inotify support had
never been officially tested with it.
* src/stat.c (human_fstype): Add file system ID definition.
* NEWS: Mention the improvement.

tee is very often used with pipes and this gives better control
when writing to them. There are 3 classes of file descriptors
that tee can write to: files(1), pipes(2), and early close pipes(3).
Handling write errors to 1 & 2 is supported at present with the caveat
that failure writing to any pipe will terminate tee immediately.
Handling write errors to type 3 is not currently supported.
To improve the supported combinations we add these options:
--write-error=warn
Warn if error writing any output including pipes.
Allows continued writing to still open files/pipes.
Exit status is failure if any output had error.
--write-error=warn-nopipe, -p
Warn if error writing any output except pipes.
Allows continued writing to still open files/pipes.
Exit status is failure if any non pipe output had error.
--write-error=exit
Exit if error writing any output including pipes.
--write-error=exit-nopipe
Exit if error writing any output except pipes.
Use the "nopipe" variants when files are of types 1 and 3, otherwise
use the standard variants with types 1 and 2. A caveat with the above
scheme is that a combination of pipe types (2 & 3) is not supported
robustly. I.e. if you use the "nopipe" variants when using both type
2 and 3 pipes, then any "real" errors on type 2 pipes will not be
diagnosed.
Note also a general issue with type 3 pipes that are not on tee's
stdout, is that shell constructs don't allow to distinguish early
close from real failures. For example `tee >(head -n1) | grep -m1 ..`
can't distinguish between an error or an early close in "head" pipe,
while the fail on the grep part of the pipe is distinguished
independently from the resulting pipe errors. This is a general
issue with the >() construct, rather than with tee itself.
* NEWS: Mention the new feature.
* doc/coreutils.texi (tee invocation): Describe the new option.
* src/tee.c (usage): Likewise.
(main): With --write-error ignore SIGPIPE, and handle
the various exit, diagnostics combinations.

Since v5.2.1-1247-g8dafbe5, tee(1) treated '-' as stdout while POSIX
explicitly requires to treat this as a file name. Revert this change,
as the interleaved output - due to sending another copy of input to
stdout - is not considered to be useful. Discussed in
http://lists.gnu.org/archive/html/coreutils/2015-02/msg00085.html
* src/tee.c (tee_files): Remove the special handling for "-" operands.

* doc/coreutils.texi (common options): Remove the "tee -" example.
(tee invocation): Document that tee(1) now treats "-" as a file name.
* tests/misc/tee.sh: Add a test case for "tee -".
While at it, re-indent the above multi-argument processing case and
extend that to 13 operands, as POSIX mandates that, too.

Each user has a maximum number of inotify watches,
so handle the cases where we exhaust these resources.
* src/tail.c (tail_forever_inotify): Ensure we inotify_rm_watch()
the watch for an inode, when replacing with a new watch for a name.
Return all used inotify resources when reverting to polling.
Revert to polling upon first indication of inotify resource exhaustion.
Revert to polling on any inotify resource exhaustion.
Diagnose resource exhaustion correctly in all cases.
Avoid redundant reinsertion in the hash for unchanged watches

This patch fixes the handling of sub-bind-mount cycles which are
incorrectly detected as the file system errors. If you bind mount the
directory 'a' to its subdirectory 'a/b/c' and then run 'du a/b' you
will get the circular dependency warning even though nothing is wrong
with the file system. This happens because the first directory that is
traversed twice in this case is not a bind mount but a child of bind
mount. The solution is to traverse all the directories in the cycle
that fts detected and check whether they are not a (bind) mount.
* src/du.c (mount_point_in_fts_cycle): New function that checks whether
any of the directories in the cycle that fts detected is a mount point.
* src/du.c (process_file): Update the function to use the new function
that looks up all the directories in the fts cycle instead of only the
last one.
* tests/du/bind-mount-dir-cycle-v2.sh: New test case that exhibits the
described behavior.

our usage with error() currently works only through an ancillary
dependency on the vfprintf gnulib module.
* src/rm.c (main): Use %PRIuMAX rather than %zu for portability.
* src/dd.c (alloc_[io]buf): Likewise for consistency.
* src/od.c (main): Likewise.
* src/split.c (set_suffix_length): Likewise.
* NEWS: Mention the rm bug fix.

If '\n' was present at the size_t boundary of a file,
then that and subsequent data would be discarded.
* src/paste.c (paste_parallel): Avoid the overflow issue
by changing the flag to a boolean rather than a count.
* NEWS: Mention the bug fix.

|
* src/df.c (filter_mount_list): Separate remote locations are
generally explicitly mounted, so list each even if they share
the same remote device and thus storage. However with --total
keep the suppression to give a more accurate value for the
total storage available.
(usage): Expand on the new implications of --total and move
it in the options list according to alphabetic order.
doc/coreutils.texi (df invocation): Mention that --total impacts
on deduplication of remote file systems and also move location
according to alphabetic order.
* tests/df/skip-duplicates.sh: Add remote test cases.
* NEWS: Mention the change in behavior.

* NEWS: Update the recent entry to also mention the avoidance
of incorrectly unlinking a multi-hardlinked "source" file when
presented with source and dest that only differ in case.
* src/copy.c (same_file_ok): Mention the case issue with same_name().
* tests/mv/hardlink-case.sh: Test the issue on HFS+.
* tests/local.mk: Reference the new test case.
* tests/mv/vfat: Remove an old related but unused test case.

We may run into a race condition if we treat hard links to the same file
as distinct files. If we do 'mv a b' and 'mv b a' in parallel, both a
and b can disappear from the file system. The reason is that in this
case the unlink on src is called and the system calls can end up being
run in the order where unlink(a) and unlink(b) are the last two system
calls. Therefore exit with an error code so that we avoid the potential
data loss.
* src/copy.c (same_file_ok): Don't set unlink_src that was used by mv,
and return false for two hardlinks to a file in move_mode.
*src/copy.c (copy_internal): No longer honor the unlink_src option,
used only by mv.
NEWS: Mention the change in behavior.
* tests/cp/same-file.sh: Augment to cover the `cp -a hlsl1 sl1` case.
* tests/mv/hard-verbose.sh: Remove no longer needed test.
* tests/local.mk: Remove the reference to hard-verbose.sh.
* tests/mv/hard-4.sh: Adjust so we fail in this case.
* tests/mv/i-4.sh: Likewise.
* tests/mv/symlink-onto-hardlink-to-self.sh: Likewise.

* src/chroot.c (is_root): Adjust to compare canonicalized paths
rather than inodes, to handle (return false in) the case where
we have a tree that is constructed by first bind mounting "/"
(thus having the same inode).
(main): Unconditionally call chroot() because it's safer
and of minimal performance benefit to avoid in this case.
This will cause inconsistency with some platforms
not allowing `chroot / true` for non root users.
* tests/misc/chroot-fail.sh: Adjust appropriately.
* NEWS: Mention the bug fixes.

* src.copy.c (copy_reg): Use fiemap to read sparse files, even
if the output is not to a regular file.
* NEWS: Mention the improvement.

With --sparse=always use fallocate(...PUNCH_HOLE...) to
avoid any permanent allocation due to speculative
preallocation employed by file systems such as XFS.
* m4/jm-macros.m4: Check for <linux/falloc.h> and fallocate().
* src/copy.c (punch_hole): A new function to try and punch
a hole at the specified offset if supported.
(create_hole): Call punch_hole() after requesting a hole.
(extent_copy): Likewise.
* NEWS: Mention the improvement.

Previously cp would not detect runs of NULs that were
smaller than the buffer size used for I/O (currently 128KiB).
* src/copy.c (copy_reg): Use an independent hole_size, set to
st_blksize, to increase the chances of detecting a representable hole,
in a run of NULs read from the input.
(create_hole): A new function refactored from sparse_copy() and
extent_copy() so we have a single place to handle holes.
(sparse_copy): Adjust to loop over the larger input buffer
in chunks of the passed hole size. Also adjust to only call
lseek once per hole, rather than at least once per input buffer.
* tests/cp/sparse.sh: Add test cases for various sparse chunk sizes.
* NEWS: Mention the improvement.
