where the file is truncated as we read.
* tests/misc/split-lchunk: Cleanup; no functional change.
|

* src/chmod.c (describe_change): Pass in the original mode,
and output this in the messages.

* cfg.mk: Include via "-include", to accommodate new tight-scope rule.
(sc_check-AUTHORS): Change the name of the rule in src/Makefile.am
to _sc_check-AUTHORS, so it doesn't conflict with this one when
this file is included into the sub-make's context.
* src/Makefile.am (_sc_check-AUTHORS): Rename from sc_check-AUTHORS.
* gnulib: Update to latest.
|
|
* src/touch.c (main): Avoid even the hint of possibility that
we'd dereference NULL upon localtime failure. Coverity reported
the potential, but it appears not to be possible, since posixtime
rejects any time for which the subsequent localtime would return NULL.

* src/split.c (lines_chunk_split): Ensure that data is only
written to stdout when k specified. Also ensure that
extra files are not created when there is more data available
than reported in the file size.
* tests/misc/split-lchunk: Verify that split -n l/k/n doesn't
generate any files, and that -n l/n always generates n files.
* NEWS: Mention the fix.

* src/timeout.c (usage): Add a space to be consistent
with other uses of "(the default)" in the documentation.

the -t and -c options

Even on a system with d_type support, the default use of --color
makes ls stat every file in order to be able to honor settings like
EXEC, STICKY, ORPHAN, SETUID, etc., because those settings require
information that is not provided by dirent.d_type. However, if
for a potentially large performance gain, you are willing to disable
those settings, you can now make ls --color give type-related coloring
and perform no stat calls at all (other than the unavoidable call-per-
command-line argument). Before this change, even with all of those
attributes disabled, ls --color would still stat every directory.
Now, we're down to the minimum of one stat call per command-line arg.
* src/ls.c (gobble_file): With --color, don't stat a
non-command-line-specified directory when no directory-coloring
attribute is enabled.
* tests/init.cfg (require_dirent_d_type_): New function.
* tests/d_type-check: New script, mostly from Pádraig Brady.
* tests/Makefile.am (EXTRA_DIST): Add it.

* doc/coreutils.texi (General output formatting): Describe how
to use dircolors to make ls --color refrain from calling stat
on a d_type-enabled file system.
Prompted by a query from Josef Bacik.

gnulib's group-member module now ensures that the group_member
function is declared in <unistd.h>, just like it is glibc.
* lib/euidaccess-stat.c: Remove inclusion of "group-member.h".

to avoid the expense of extent_copy's unconditional use of
FIEMAP_FLAG_SYNC.
* src/copy.c (copy_reg): Do not attempt extent_copy on a file
that appears to have no holes.
* NEWS (Changes in behavior): Document this. At first I labeled this
as a bug fix, but that would be inaccurate, considering there is no
documentation of FIEMAP semantics, nor even consensus among kernel
FS developers. Here's hoping SEEK_HOLE/SEEK_DATA support will soon
make it into the linux kernel.
|
|
* src/copy.c (HAVE_STRUCT_STAT_ST_BLOCKS): Define to 0 if undefined,
so we can use it in the return expression, here:
(is_probably_sparse): New function, factored out of...
(copy_reg): ...here. Use the new function.
|
|
* src/copy.c (extent_copy): Do not treat "unwritten extents" specially.
Otherwise, with a release-candidate 2.6.39-rc3 kernel, XFS or ext4,
when using gold as your linker, and if you forget to run "make check",
you could end up installing files full of zeros instead of the expected
binaries. For a lot of discussion, see
http://thread.gmane.org/gmane.comp.file-systems.xfs.general/37895
* tests/cp/fiemap-empty: Disable this test.
|
|
* src/extent-scan.c (extent_need_sync): Always return true,
to make the sole caller always use FIEMAP_FLAG_SYNC.
This will doubtless have an undesirable performance impact,
but we'll mitigate that shortly, by using extent_copy only on
files with holes.

When running the erroneous command, cp -rl A D D, and depending on the
structure of directories A and D and the file system type (because that
changes order of dir. entry traversal), cp would sometimes fail to
detect that D was being copied into D, and would create D/D/D/D/D/...
until it hit PATH_MAX or exhausted some resource.
I noticed this via the occasional failure of the cp/into-self test
when run using a ZFS file system. It is occasional because the bug
is dependent on the order in which directory entries are traversed,
and that is apparently indeterminate with ZFS.
Technically, with the current recursive implementation, there is no
risk of an infinite loop, due to stack limitations, but with an
eventual fts-based implementation, it might have iterated until
disk space or inodes are exhausted.
* src/copy.c (copy_dir): Avoid copy-into-self interminable loop on
systems with large PATH_MAX. On other systems, diagnose the copy-into-
self error consistently. Handle the parameter,
first_dir_created_per_command_line_arg, correctly when there are two
or more sub-directories.
|
|
* src/copy.c (extent_copy): Treat an allocated but empty extent
much like a hole. I.E. don't read data we know is going to be NUL.
Also we convert the empty extent to a hole only when SPARSE_ALWAYS
so that the source and dest have the same allocation. This will
be improved soon, when we use fallocate() to do the allocation.
* tests/cp/fiemap-empty: A new test for efficiency and correctness
of copying empty extents.
* tests/Makefile.am: Reference the new test.
* NEWS: Mention the change in behavior.
|
|
* src/extent-scan.c (extent_scan_read): Add a more stringent check
for OFF_T overflow, to ensure subsequent code is immune.
Detect overlapping extents and adjust, so as files always copied.
Detection using a single scan with fallback to a standard copy
was thought too expensive in memory or time.
* NEWS: Mention the fix

This bug was introduced in commit ca9e212c, 2009-09-24,
"cp, mv: use linkat to guarantee semantics", which
inadvertently disabled the creation of hardlinks to symlinks.
However rather than implementing the intention of that commit
and relying on gnulib linkat emulation, we'll revert to the
previous emulation as that maintains ownership and timestamps.
* src/copy.c (copy_internal): Use our existing hardlink to
symlink emulation when link() might dereference the symlink.
Also ensure that we copy the timestamps of the original symlink
when we use the emulation.
* tests/cp/link-symlink: Add a test to ensure timestamps copied.
* tests/Makefile.am: Reference the new test.
* NEWS: Mention the fix.
