hard links by default.
* src/dircolors.c: Rename HARDLINK -> MULTIHARDLINK, hl -> mh.
* src/dircolors.hin: Do not colorize files with multiple hard links by
default.
* tests/Makefile.am: Rename the test case accordingly.
* tests/ls/multihardlink: Additionally test ls' default behavior
and factor out some duplication.
* NEWS: Mention the change in behavior.
|
|
* src/sort.c (register_proc): Handle hash_insert failure.
|
|
* src/dircolors.hin: Add screen-256color-bce.
|
|
* src/dircolors.hin: Add .xz, .txz, .tbz and .tlz.
|
|
* src/chroot.c (set_additional_groups): Add comments.
Given an empty or all-comma group list, diagnose it and return nonzero.
When more than one group is invalid, diagnose all of them,
not just the first.
(main): Honor --groups= also when --userspec= is not specified.
Now that set_additional_groups consistently diagnoses its failures,
don't diagnose it separately here.
* tests/chroot/credentials: Do not invoke with an empty group list.
|
|
* src/chroot.c (main): Initialize both "uid" and "gid". To -1.
This also allows one to set the user-ID or primary group-ID to 0,
in case it's not that already.
* tests/chroot/credentials: Test for the above.
|
|
* src/chroot.c (main): Exit upon set-group-ID or set-user-ID failure.
|
|
* src/head.c (usage): Use -n K, not -n N, to avoid confusion.
* src/tail.c (usage): Likewise.
* doc/coreutils.texi (head invocation, tail invocation):
Likewise.
Reported by Christophe Lyon.

* src/sort.c (main): handle the new --human-numeric-sort option (-h).
(human_numcompare): A new function to compare SI and IEC suffixes
before falling back to the standard --numeric comparison.
(find_unit_order): A new helper function to find the order
of magnitude of a number string as determined by its suffix.
(check_mixed_SI_IEC): A new helper function to exit with error
if both SI and IEC suffixes are presented.

with examples to show that they can be combined.
Addresses <http://savannah.gnu.org/bugs/?24974>.
* doc/coreutils.texi (comm invocation): Mention that the
column separators are suppressed along with the column.
Suggestion from Dan Jacobson.
* man/comm.x: Reference other commands that match adjacent lines.
* man/join.x: ditto.
* man/uniq.x: ditto.

|
* src/truncate.c (main): Pass unsigned characters to isspace.
* NEWS: Mention this.
|

* doc/coreutils.texi (uniq invocation): Simplify the
text to remove the inconsequential mentioning of order,
while implying that LC_COLLATE can alter equality comparisons.
* src/comm.c (usage): Mention LC_COLLATE is significant.
* src/join.c (usage): Ditto.
* src/uniq.c (usage): Ditto. Also improve the summary.
Suggestion from Andries Brouwer

* src/Makefile.am (check-AUTHORS): Set locale.
|

Use gnulib's new priv-set module and updated write-any-file.
With them, the remove-called can_write_any_file function no
longer tries to drop the unlink-directory privilege, so now
each caller of remove must do that separately, calling
priv_set_remove_linkdir.
* bootstrap.conf (gnulib_modules): Add priv-set.
* src/rm.c: Include "priv-set.h".
(main): Call priv_set_remove_linkdir.
* src/mv.c (main): Likewise.
* gnulib: Update submodule to latest.
|
|
* src/Makefile.am (check-AUTHORS): Revert back to using
en_US.UTF-8, to ease parsing (English-only) text around the
list of names, even when .po files are not installed.
Reported by Andreas Schwab.
Along the way, use $(AM_V_GEN), not "@".
(sc_tight_scope): Use $(AM_V_GEN) here, too.
* gnulib: Update submodule to latest, for the proper_name_utf8 fix
that makes --version output print the UTF-8 rendering of author names
in more cases.
|
|
* src/df.c (main): Update comment to match.
|
|
* src/df.c (main): When iterating over command-line arguments,
attempting to ensure each backing file system is mounted, use
open, not stat. stat is no longer sufficient to trigger
automounting, in some cases. Based on a suggestion from Ian Kent.

* src/copy.c (errno_unsupported): New function.
(copy_attr_error, copy_internal): Use it.
|
|
* src/copy.c (copy_attr_by_fs): Always print diagnostics when preserving
xattrs is required.
(copy_attr_by_name): Likewise.
(copy_reg): Always print diagnostics when preserving SELinux
context is required.
(copy_internal): Likewise. Also, do not ignore ENOTSUP and ENODATA
errors when preserving SELinux context is required.

|
|
* src/Makefile.am (dircolors.h, wheel-size.h, wheel.h, fs.h):
(version.c, version.h): Use $(AM_V_GEN) only as a prefix of an existing
command. Otherwise, it provokes warnings from some "make" programs.
Suggestion from Ralf Wildenhues.
|
|
* src/Makefile.am (check-AUTHORS): When this test is skipped, be
sure to avoid all commands in the recipe, not just those passed
to the first shell.
|
|
* src/Makefile.am (dircolors.h, wheel-size.h, wheel.h, fs.h):
(version.c, version.h): Mark with $(AM_V_GEN) and $(AM_V_at),
so that the latest automake prints "GEN $@" by default.
|
|
* src/sort.c (avoid_trashing_input): Fix an off-by-one error and
guard the use of memmove.
* NEWS (Bug fixes): Mention it.
* tests/misc/sort: Add tests to exercise the offending code.
* THANKS: Update.

run as part of "make check".
* src/Makefile.am (check-AUTHORS): Don't depend on en_US.UTF-8.
Instead, use the French UTF8 locale, if configure found one.
If not found, just skip the test.
|
|
Move the check-AUTHORS rule from "syntax-check" to "check".
* maint.mk (local-checks-available): Remove check-AUTHORS.
(check-AUTHORS): Remove rule.
* src/Makefile.am (CLEANFILES): Add $(no_install__progs),
since they too are built sometimes.
(check-AUTHORS): Split a longer-than-80 sed command.
(../AUTHORS): Remove obsolete rule.

Remove the optimization that avoided up to 50% of cp's read syscalls.
Do not assume that a short read on a regular file indicates EOF.
When reading from a file in /proc on linux [at least 2.6.9 - 2.6.29]
into a 4k-byte buffer or larger, a short read does not
always indicate EOF. For example, "cp /proc/slabinfo /tmp"
copies only 4068 of the total 7493 bytes. This optimization
(25719a33154f0c62ea9881f0c79ae312dd4cec7a, Improve performance a bit
by optimizing away; 2005-11-24) appears to have been worth less than
a 2% speed-up (and usually much less), so the impact of removing it
is negligible.
* src/copy.c (copy_reg): Don't exit the loop early.
* tests/cp/proc-short-read: New test, lightly based on a suggestion
from Mike Frysinger, to exercise this fix.
* tests/Makefile.am (TESTS): Add cp/proc-short-read.
* NEWS (Improve robustness): Mention this change.

* bootstrap: Fix comment typos.
* src/pr.c: Likewise.

* src/Makefile.am (sc_tight_scope): Depend on $(bin_PROGRAMS),
not $(all_programs)

src/install.c: Print a warning when --preserve_context
rather than --preserve-context is used as per FIXME.

Reported by Samuel Thibault and Stéphane Raimbault, as the glibc fr_FR
locale has recently changed to use the official but variable width
abbreviated month names. Other glibc locales also have variable widths.

* NEWS: Mention the fix
* gl/lib/mbsalign.c: A new module to align and truncate a
string in a specified number of screen cells, while handling
multi-byte characters appropriately.
* gl/lib/mbsalign.h: Ditto
* gl/modules/mbsalign: Ditto
* bootstrap.conf: Reference the new module
* src/ls.c (abmon_init): New function, precompute the abbreviated
months aligned left in a minimum width column <= 5 screen cells.
(align_nstrftime): New function, replace the first %b in the
format specification to strftime with the precomputed month string.
Note using the cached month strings speeds up `ls -lU` by around 17%
on glibc-2.7-2 on linux at least. Also if we implement this function
using heap storage rather than automatic storage, and use snprintf
instead of strcpy, ls will slow down by 2% and 1% respectively
(i.e. a net gain of 14% rather than 17%).
* tests/ls/abmon-align: A new test to test ls alignment for
various formats and locales
* tests/Makefile.am: Reference the new test
|
|
* src/ls.c: Update the -v help description
* src/sort.c: Update the -V help description

* src/Makefile.am (sc_tight_scope): Ignore leading underscores in symbols.
|
|
* src/df.c (known_value): New function, which also works on AIX
/proc file systems.
(df_readable, show_dev): Use it instead of hardcoding comparison to
UINTMAX_MAX. Suggested by Jim Meyering and Matthew Woehlke.
|
|
* src/df.c (show_dev): Don't add UINTMAX_MAX to grand totals, as that
value indicates that the true value is unknown; adding it effectively
subtracts 1 from the total, whereas we want to leave the total alone.

This is an alternative to my 9 March patch labeled "Silently lower
nmerge; don't (sometimes incorrectly) range-check"
<http://lists.gnu.org/archive/html/bug-coreutils/2009-03/msg00070.html>.
It differs by not using 'dup' to probe for extra file descriptors;
instead, it simply calls 'open' (and 'pipe') to open files and pipes,
until one of these calls fails due to file descriptor exhaustion; it
then backs off by 1, does a merge with the files that it has opened,
and then retries with the (now-smaller) number of files.
This patch requires quite a few more changes to the source code than
the earlier patch, but it is in some sense "better" because it doesn't
need to call "dup" ahead of time in order to decide whether "open" or
"pipe" will fail. Also, it's more robust in the case where "open" or
"pipe" fails with errno==EMFILE because some system-wide limit is
exhausted.
* src/sort.c (create_temp_file): New arg SURVIVE_FD_EXHAUSTION.
(stream_open): New function, containing guts of xfopen.
(xfopen): Use it.
(pipe_fork): Set errno on failure.
(maybe_create_temp): New function, containing guts of create_temp.
(create_temp): Use it.
(open_temp): Distinguish failures due to file descriptor exhaustion
from other failures, and on fd exhaustion return a notice to caller
rather than dying. Don't test execlp's return value; when it returns,
it *always* returns -1.
(open_input_files): New function.
(mergefps): New arg FPS. It's now the caller's responsibility to open
the input and output files. All callers changed.
(mergefiles): New function.
(avoid_trashing_input, merge): Handle the case where a single merge
can't merge as much as we wanted due to file descriptor exhaustion, by
merging as much as we can and then retrying.
* tests/Makefile.am (TESTS): Add misc/sort-continue.
* tests/misc/sort-continue: New file.
* THANKS: Add Glen Lenker and Matt Pham who coauthored this patch.

* src/system.h (io_blksize): Move definition down, so it follows that

* copy.c (copy_attr_by_fd): Reduce xattr diagnostics for 'cp -a'.
(copy_attr_by_name): Likewise.

cp -a, with no added diagnostics.
* NEWS: Mention the change.
