* 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): If sparse_copy() failed, then an
erroneous error about failing to extend the file would be reported.
|

* 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.

* man/timeout.x: The 2038 that the sentence is referring to is the year
2038, not 2038 seconds (the default unit used for timeouts).

Prompted by http://hydra.nixos.org/build/15682577
with GCC 4.8.3 on i686
src/tac.c:557:6: error: assuming signed overflow does not occur
when simplifying conditional to constant [-Werror=strict-overflow]
if (bytes_copied < 0)
This happens because copy_to_temp() is inlined in tac_nonseekable(),
thus reducing the comparison to the bytes_copied variable in
copy_to_temp. Now this can't overflow on either 32 or 64 bit
due to the protection of the preceding fwrite(). We could use a
guard like "if (bytes_copied <= OFF_T_MAX - bytes_read)" to avoid
the warning, but rather than a runtime branch, just use an unsigned
type to avoid apparent signed overflow on systems where the accumulation
is not promoted to unsigned (32 bit size_t, 64 bit off_t).
* src/tac.c (copy_to_temp): Increment an unsigned type to
avoid the subsequent signed overflow warning.

new status=progress level is used. Adjust the handling and
description of the status= option so that they're treated as
mutually exclusive levels, rather than flags with implicit precedence.
* doc/coreutils.texi (dd invocation): Document the new progress
status level. Reference the new level in the description of SIGUSR1.

On some filesystems (BTRFS), moving a file within the filesystem may
cross subvolume boundaries and we can use a lightweight reflink copy,
similar to what cp(1) can do, which is faster than a full file copy.
This is enabled by default because it's only an optimization for
the fall back copy and does not break user expectations or usability.
* src/mv.c (cp_option_init): Set the reflink mode to AUTO.
* NEWS: Mention the improvement.

* src/stty.c (usage): Exclude unsupported options from --help,
which for example impacts the "dsusp" and "cdtrdsr" options on Linux.

"E.g." stands for latin "exempli gratia" which is typically read
as "for example". "E.g." does not stand for the word "example".
As such, "for e.g." might be read as "for for example".
Fix this usage by simply replacing "e.g." with "example".
|

* man/local.mk (.x.1): Move the program name argument down after
the last option argument when calling $(run_help2man).
While the other way would be accepted for the GNU help2man program,
it is not for the 'dummy-man' script (called as a fallback on
systems lacking perl).
The wrong order was introduced in commit v8.21-119-gb3578fc while
adding the --info-page option.

* man/dummy-man: Fix argument count check, now only permitting
exactly 1 argument, the program name.

* .gitignore: Remove reference to no longer generated make file.
* configure.ac: Don't bother generating placeholder make file.
* man/local.mk: Hardcode the man page deps list for normal builds
to be compatible with all make implementations and configure options.
Note in SINGLE_BINARY mode, all man pages will be generated on
any change to the coreutils binary, but development will generally
not be done in this mode, so this shouldn't be an issue.

the erroneous directory hardlink warning with -H.

specified directory case, and the existing multiply specified file case.

* NEWS: Mention the bug fix.

* src/system.h (emit_ancillary_info): Take the invariant PROGRAM_NAME
as a parameter, so that consistent references are made to online docs
and texinfo nodes, when a --program-prefix is in place. Note the
man pages don't need this fix as they're generated before the program
prefix is used.
* NEWS: Mention the improvements in references to online documentation.
|
|
* src/system.h (emit_ancillary_info): For commands that don't have
a 1:1 mapping with the texinfo node names, provide a mapping to
the correct node.

checking this.

On XFS, when creating the ~2G test file 'big' in a for-loop by
appending 20M each time, the file ends up using ~4G - visible in
'st_blocks'. The unused space would be reclaimed later.
This feature is called "speculative preallocation" which aims at
avoiding fragmentation.
According to the XFS FAQ [1], there are two particular aspects of
XFS speculative preallocation that are triggering this:
1. "Applications that repeatedly trigger preallocation and reclaim
cycles [after file close] can cause fragmentation.
Therefore, this pattern is detected and causes the preallocation
to persist beyond the lifecycle of the file descriptor."
2. "Preallocation sizes grow as files grow larger."
[1] http://xfs.org/index.php/XFS_FAQ
Avoid one of the above by only doing a single close (reclaim cycle).
* tests/du/2g.sh: Similar to the fix for a dd test (see commit
v8.22-65-g7c03fe2), avoid speculative preallocation by creating
the 'big' file in one go instead of appending to it in the loop.
Remove debugging statements as the output with 'set -x' is
sufficient nowadays.

* src/system.h (emit_ancillary_info): Add a direct reference

redirects were put in place on www.gnu.org to allow for concise links.
* help2man: Adjust to add the "online help" link (and subsequent
translation bugs link) to a "REPORTING BUGS" section.
Also add the concise links for further information in --help
to the "SEE ALSO" section, and dispense with the more verbose
default for that.

old form: coreutils '$cmd invocation'
new form: '(coreutils) $cmd invocation'
The old form erroneously referenced the node for the 'coreutils'
multi-call program. Now that problematic node name was renamed
in commit v8.23-18-g72e470b, but the newer less ambiguous form
also has the advantage of working with the pinfo viewer for example.

v8.23 has a test failure on Fedora rawhide build servers
in tests/df/skip-duplicate.sh. This was due to no '/'
entry being output by df. That was due to an inaccurate
/proc/mounts on the build environment as stat(/mnt/point)
identified all these /proc/mounts entries as having the
same device id:
/ rootfs
/ /dev/md1
/dev devtmpfs
/run tmpfs
/boot /dev/md0
/proc/filesystems /dev/md1
Since the device name on the right changes for a given id,
that causes the entries to be continually replaced, thus
resulting in no '/' entry. I'm guessing this is due to
the mock environment bind mounting unneeded or sensitive
items to a dummy file on the host / (/dev/md1) though
have not looked into those details.
So rather than relying on an accurate /proc/mounts,
the attached patch takes a more conservative replacement
approach and only swaps a new device entry when the
mount point matches. That should handle all practical
cases while also avoiding this situation.
* src/df.c (filter_mount_list): Only replace entries with
different device names when the mount point also matches.
