2010-02-01join: add --header option to always output the first lineAssaf Gordon
This essentially allows one to use --check-order with headings. Note join without --check-order will already handle the common case where headings do match in each file, however using --check-order will fail often when the header sorts after the first line of data. Note also that this will join header lines from each file even if they don't match, with headings from the first file being used. * NEWS: Mention the new option. * doc/coreutils.texi (join invocation): Describe the new option. * src/join.c (usage): Likewise. (join): Join the header lines unconditionally. * tests/misc/join: Add 5 new tests.
2010-02-01ls --color: don't emit a final no-op escape sequenceJim Meyering
* src/ls.c (main): With --color, avoid emitting the final color- resetting escape sequence when it would be a no-op. * tests/ls/color-clear-to-eol: Adjust expected output accordingly. * tests/ls/color-dtype-dir: Likewise. * tests/ls/multihardlink: Likewise. * tests/ls/stat-free-symlinks: Likewise. * tests/misc/ls-misc: Likewise. * NEWS (Changes in behavior): Mention it. C de-Avillez rebased and adapted four of the new sl-dangle* tests in tests/misc/ls-misc. Reported by Jim Avera in http://bugs.launchpad.net/ubuntu/+source/coreutils/+bug/494663
2010-01-13tests: don't silently skip the sort-version testsJim Meyering
* tests/misc/sort-version: Don't use <<- and indented here-doc contents. s/<<-/<</ and unindent the here-document contents. Otherwise, bash would ignore the indented delimiter and use EOF, thus silently skipping this test. OpenBSD5.4's shell reported the failure: $ printf 'cat<<-x\n foo\n x\n'|sh sh: <stdin>[4]: here document `x' unclosed [Exit 1] by contrast, bash warns but still exits successfully: $ printf 'cat<<-x\n foo\n x\n'|bash && echo you lose bash: line 3: warning: here-document at line 1 delimited by \ end-of-file (wanted `x') foo x you lose
2010-01-01ls: fix color of broken symlinks colored as targetEric Blake
* src/ls.c (print_color_indicator): When using 'LINK target' in dircolors, treat broken symlink as C_ORPHAN. * tests/misc/ls-misc (sl-dangle2, sl-dangle3, sl-dangle4) (sl-dangle5): Test for it, and add more coverage. * NEWS: Document it. * THANKS: Update. Reported by Chris Jones.
2010-01-01maint: add a few copyrights; remove obsolete README fileJim Meyering
* tests/README: Remove long-obsolete file. * tests/Makefile.am (EXTRA_DIST): Remove README. * tests/misc/truncate-dir-fail: Add copyright comment. * tests/misc/selinux: Likewise. * tests/misc/chcon: Likewise. * tests/misc/chcon-fail: Likewise. * tests/sample-test: Use only 2010 in this list.
2010-01-01maint: update all FSF copyright year lists to include 2010Jim Meyering
Use this command: git ls-files | grep -v COPYING \ | xargs env UPDATE_COPYRIGHT_USE_INTERVALS=1 \ build-aux/update-copyright
2009-12-23wc: line-buffer the printed countsPádraig Brady
* src/wc.c (main): Set stdout to line buffered mode to ensure parallel running instances don't intersperse their output. This adds 6.5% to the run time in the worst case of many zero length files, but has neglible impact for standard sized files. * tests/misc/wc-parallel: New test for atomic output. * tests/Makefile.am: Reference it. * NEWS: Mention the fix This is similar to commit 710fe413, 20-10-2009, "md5sum, sha*sum, sum: line-buffer the printed checksums"
2009-12-10tests: avoid spurious failure when run via valgrindJim Meyering
* tests/misc/printenv: Ignore LD_PRELOAD differences.
2009-12-08maint: remove an erroneous commentPádraig Brady
* tests/misc/timeout: Remove an erroneous comment introduced through copy and paste.
2009-12-08sort: fix failure if sort's parent has ignored SIGCHLDPádraig Brady
* src/sort.c (main): Reset the SIGCHLD handler to the default as otherwise wait() could return an error. * tests/misc/sort-compress: Set the CHLD handler in a subshell to SIG_IGN to ensure the sort command resets it to SIG_DFL. * NEWS: Mention the fix.
2009-12-08timeout: fix failure if timeout's parent has ignored SIGCHLDPádraig Brady
* src/timeout.c (main): Reset the SIGCHLD handler to the default as otherwise wait() could return -1 and set errno to ECHILD. This condition was ignored until commit 0b1dcf33, on 31-08-2009, "timeout: defensive handling of all wait() errors" but subsequently timeout would run the command correctly but then fail with an error message. * tests/misc/timeout: In a subshell set the CHLD handler to SIG_IGN to ensure the timeout command resets it to SIG_DFL. * NEWS: Mention the fix.
2009-12-08tests: fix stty-row-col failure on small fixed terminalsPádraig Brady
* tests/misc/stty-row-col: Linux virtual consoles at least, issue an error if you try to increase their size, so skip the test if we can't increase the dimensions of the tty by 1 cell. Reported by Matthew Burgess.
2009-12-08tests: fix stty failure with serial control settingsPádraig Brady
* tests/misc/stty: Don't check the serial control settings as these are ignored by various Linux kernels. Reported by Matthew Burgess.
2009-11-20maint: correct comments in test scriptsJim Meyering
* tests/misc/pwd-long: Fix spelling of cygwin1.dll in comment. * tests/rm/fail-eperm: Likewise. Reported by Eric Blake.
2009-11-19tests: avoid spurious failures due to insecure directory in PATHJim Meyering
These tests perform no PATH search, and used to simply delete PATH from the environment. However, that is not portable, as seen on Cygwin, where cygwin.dll must be resolvable via PATH when starting a sub-shell. With commit 0cc04241, we took the alternate approach of untainting the incoming $ENV{PATH}, but that fails when it contains an other-writable directory. Instead, now we hard code it to '/bin:/usr/bin'. * tests/misc/pwd-long: Hard code $ENV{PATH} to a safe value. * tests/rm/fail-eperm: Likewise. Reported by Gilles Espinasse, Andreas Schwab, and Bauke Jan Douma.
2009-11-14tests: help-version: exit nonzero when $built_programs is emptyJim Meyering
* tests/misc/help-version: Use "Exit 1", rather than "Exit $fail" with fail defined to 0 when $built_programs is empty.
2009-11-14tests: avoid a spurious failure on a loaded systemPádraig Brady
* tests/misc/timeout-parameters: This test could fail due to the 1-second timeout expiring before a command of "no_such" could be exec'd and fail. Increase to 10 seconds.
2009-11-13tests: avoid a spurious timeout on a heavily-loaded systemJim Meyering
* tests/misc/timeout-parameters: This test would fail due to the 1-second timeout expiring before a command of "." could be exec'd and fail. Increase to 10 seconds.
2009-11-07mktemp: fix bug with -q and closed stdoutEric Blake
If stdin or stdout is closed, then freopen(,stderr) can violate the premise that STDERR_FILENO==fileno(stderr), which in turn breaks mktemp -q. * bootstrap.conf (gnulib_modules): Add freopen-safer. * src/mktemp.c (includes): Use stdio--.h. * tests/misc/close-stdout: Enhance test to catch bug.
2009-11-06nproc: A new program to count the available processorsGiuseppe Scrivano
* AUTHORS: Add my name. * NEWS: Mention it. * README: Likewise. * bootstrap.conf (gnulib_modules): Add nproc. * doc/coreutils.texi (nproc invocation): Add nproc info. * man/Makefile.am (nproc.1): Add dependency. * man/nproc.x: New template. * man/.gitignore: Ignore generated man page. * po/POTFILES.in: Add src/nproc.c. * src/.gitignore: Exclude nproc. * src/Makefile.am (EXTRA_PROGRAMS): Add nproc. * src/nproc.c: New file. * tests/Makefile.am (TESTS): Add misc/nproc-{avail,positive}. * tests/misc/nproc-avail: New file. * tests/misc/nproc-positive: New file.

Penance for botching the conflict resolution while rebasing my series. * tests/misc/mktemp (check_tmp): Test for the bug when wrong parameter is used.
2009-11-05mktemp: add suffix handlingEric Blake

(AUTHORS): Add myself. * AUTHORS (mktemp): Likewise. * tests/misc/mktemp: Test new option. * doc/coreutils.texi (mktemp invocation): Document it. * NEWS: Likewise. Fixes http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=548316.

* tests/misc/mktemp: Add more coverage.
2009-11-05mktemp: don't leave file behind on write failureEric Blake
* src/mktemp.c (main): Remove just-created file if stdout had problems. * bootstrap.conf (gnulib_modules): Add remove. * tests/misc/close-stdout: Test it. * NEWS: Document it.
2009-10-30tests: factor 350 fail=0 initializations into test-lib.shJim Meyering
Run this command to remove the factored-out "fail=0" lines. perl -ni -e '/^fail=0$/ or print' $(g grep -l '^fail=0$') * tests/test-lib.sh: Initialize fail=0 here, not in 300+ scripts. * tests/...: nearly all bourne shell scripts Suggested by Eric Blake.
2009-10-30tests: remove the less-regular fail=0 assignments manuallyJim Meyering
* tests/tail-2/assert-2: * tests/tail-2/assert: * tests/cp/file-perm-race: * tests/misc/df: * tests/misc/truncate-dir-fail:
2009-10-29tests: don't let a fail=1 env. setting induce unwarranted test failureJim Meyering

Fix the offenders: * tests/cp/acl: Set fail=0 * tests/cp/backup-is-src: Likewise. * tests/cp/file-perm-race: Likewise. * tests/cp/reflink-auto: Likewise. * tests/cp/same-file: Likewise. * tests/ln/backup-1: Likewise. * tests/misc/su-fail: Likewise. * tests/misc/truncate-owned-by-other: Likewise. * tests/mkdir/p-3: Likewise. * tests/mkdir/selinux: Likewise. * tests/mkdir/special-1: Likewise. * tests/mv/acl: Likewise. * tests/mv/backup-is-src: Likewise. * tests/mv/diag: Likewise. * tests/mv/force: Likewise. * tests/mv/hard-link-1: Likewise. * tests/mv/into-self-3: Likewise. * tests/mv/sticky-to-xpart: Likewise. * tests/touch/now-owned-by-other: Likewise.
2009-10-28nice, nohup, su: detect write failure to stderrEric Blake
These programs can print non-fatal diagnostics to stderr prior to exec'ing a subsidiary program. However, if we thought the situation warranted a diagnostic, we insist that the diagnostic be printed without error, rather than blindly exec, as it may be a security risk. For an example, try 'nice -n -1 nice 2>/dev/full'. Failure to raise priority (by lowering niceness) is not fatal, but failure to inform the user about failure to change priority is dangerous. * src/nice.c (main): Declare failure if writing advisory message to stderr fails. * src/nohup.c (main): Likewise. * src/su.c (main): Likewise. * tests/misc/nice: Test this. * tests/misc/nohup: Likewise. * NEWS: Document this.
2009-10-28echo, printf: interpret \e as the Escape characterPádraig Brady
Match gcc, perl, bash, ksh, tcsh, ... in supporting \e. * src/printf.c (print_escape_char): Output \x1B when \e encountered. * src/echo.c (main): Likewise. * src/stat.c (print_escape_char): Likewise. * doc/coreutils.texi (echo invocation): Add \e to the list. * tests/misc/printf: Verify that \e outputs \x1B. * NEWS: Mention the change in behaviour.
2009-10-28printenv: ignore bogus variable namesEric Blake
Exposed by env a=b=c printenv a=b. * src/printenv.c (main): Silently reject = in names. * tests/misc/printenv: Test for it. * NEWS: Document this.
2009-10-27env, printenv: add -0/--null optionEric Blake
Allows for unambiguous processing when environment values (or even non-portable names!) contain newline. * src/env.c (longopts): Add new option. (usage): Document it. (main): Implement it. * src/printenv.c (longopts): New variable. (usage): Document new option. (main): Implement it. * doc/coreutils.texi (Common options): New macro optNull. (du invocation, env invocation, printenv invocation): Use it. * NEWS: Mention this. * tests/misc/env-null: New test. * tests/Makefile.am (TESTS): Run it.
2009-10-27tests: add printenv coverageEric Blake
* tests/misc/printenv: New test. * tests/Makefile.am (TESTS): Run it. * .gitignore: Ignore more cruft.
2009-10-27tests: fix PATH problems on cygwinEric Blake
* tests/misc/sort-compress: Remove non-portable over-restriction of PATH; besides, commit 3ea177e changed sort to no longer default to gzip. * tests/rm/fail-eperm: Untaint, rather than clear, PATH. * tests/misc/pwd-long: Likewise. Also skip test if long path cannot be created. (normalize_to_cwd_relative): Use eq rather than ==, since cygwin perl doesn't properly handle 64-bit ino_t numerically.
2009-10-26tests: clean up tests of env -- handlingEric Blake
The comment in env.c about -- handling has not matched the behavior in the code since the initial commit back in 1992. * src/env.c: Fix bogus comment. * tests/misc/env: Further tweaks, avoiding PATH problems inherent in testing -i, and testing program name containing =. * doc/coreutils.texi (env invocation): Mention that intermediate program is needed to invoke program with name containing =.
2009-10-26doc: document PATH interactions with envEric Blake
* doc/coreutils.texi (env invocation): Mention that PATH is modified prior to exec. * tests/misc/env: Test this.
2009-10-26env: reject bogus -u argumentsEric Blake
* src/env.c (main): Use unsetenv rather than putenv to remove items from environ, and check for failure. * bootstrap.conf (gnulib_modules): Add unsetenv. * tests/misc/env: Test this. * NEWS: Document it.
2009-10-26tests: avoid file name not portable to cygwinEric Blake
* tests/misc/chroot-fail: Use 'no_such', not '...', since cygwin 1.5 silently strips trailing dots. * tests/misc/nice-fail: Likewise. * tests/misc/stdbuf: Likewise. * tests/misc/timeout-parameters: Likewise.
2009-10-26tests: adjust new env test not to failJim Meyering
* tests/misc/env: Create ./-i as a link to our "echo" binary, rather than as a bourne shell script, so that env can exec it. Set PATH to ".".
2009-10-26tests: nice: adjust new tests to work more portablyJim Meyering
* tests/misc/nice (tests): Accommodate a nice program for which "nice -n -1 nice" prints nothing. It should print -1 or (usually) 0. Otherwise, we'd get syntax errors.
2009-10-23tests: test recent status changesEric Blake
* tests/misc/nice: Enhance test. * tests/misc/chroot-fail: New test. * tests/misc/env: Likewise. * tests/misc/nice-fail: Likewise. * tests/misc/su-fail: Likewise. * tests/Makefile.am (TESTS): Run new tests.

2009-10-23nohup: use EXIT_CANCELED if not POSIXLY_CORRECTEric Blake
* src/nohup.c (NOHUP_FAILURE): Rename... (POSIX_NOHUP_FAILURE): ...to this. (main): Pay attention to POSIXLY_CORRECT, to determine whether to use status 125 or 127. * doc/coreutils.texi (nohup invocation): Document this. * NEWS: Likewise. * tests/misc/invalid-opt (exit_status): Adjust expected results. * tests/misc/help-version (expected_failure_status): Likewise. * tests/misc/nohup: Likewise.
2009-10-23chroot, env, nice, su: use EXIT_CANCELED for internal failureEric Blake

2009-10-23tests: accommodate BSD getoptEric Blake
* tests/misc/invalid-opt (err_subst): Support alternate spelling.
2009-10-21md5sum, sha*sum, sum: line-buffer the printed checksumsPádraig Brady
* src/md5sum.c (main): Set stdout to line buffered mode to ensure parallel running instances don't intersperse their output. This adds 5% to the run time in the worst case of many zero length files, or 2% with standard file sizes. * src/sum.c (main): Likewise. * tests/misc/md5sum-parallel: New test for atomic output. * tests/Makefile.am: Reference it. * NEWS: Mention the fix
2009-10-08stat: test recent patchEric Blake
* tests/misc/stat-slash: New test. * tests/Makefile.am (TESTS): Run it.
2009-10-07md5sum, sha*sum: also accept openssl checksum syntaxGuenter Knauf
* src/md5sum.c (split_3): Accept openssl checksum syntax, which differs only by two spaces from that of the bsd checksum tools: openssl: MD5(f)= d41d8cd98f00b204e9800998ecf8427e bsd: MD5 (f) = d41d8cd98f00b204e9800998ecf8427e
2009-09-29stat: interpret "-" as standard inputJim Meyering
* src/stat.c (do_stat): Interpret a command line argument of "-" to mean "standard input", like many other tools do. (do_statfs): Fail upon any attempt to use "-". * NEWS (Changes in behavior): Mention it. * tests/misc/stat-hyphen: New test, to exercise the above. * tests/Makefile.am (TESTS): Add misc/stat-hyphen.
2009-09-14maint: use #!/bin/sh consistently in shell-based test scriptsJim Meyering
* tests/misc/sort-continue: Change first line to standard #!/bin/sh, not #!/bin/bash (though it doesn't matter, since each is invoked via $(SHELL) dir/test-name.
