2016-01-10tests: fix races wrt output files of background processesBernhard Voelker
At least the false positive in tail-2/follow-stdin.sh could be seen on a 4-core i5 system with -j8. Fix similar cases. too. * tests/tail-2/follow-stdin.sh: Empty the 'out' file in each iteration. Otherwise, under heavy system load, 'check_tail_output' would see the expected output from the previous round before tail would have the chance to come up in the background. While at it, move the creation of the 'exp' file out of the loop. * tests/dd/stats.sh: Empty the output file of the background process here, too. * tests/misc/cat-buf.sh: Likewise. * tests/misc/stdbuf.sh: Likewise. * tests/tail-2/wait.sh: Likewise.
2016-01-01maint: update all copyright year number rangesPádraig Brady
Run "make update-copyright" and then... * gnulib: Update to latest with copyright year adjusted. * tests/init.sh: Sync with gnulib to pick up copyright year. * bootstrap: Likewise. * tests/sample-test: Adjust to use the single most recent year.
2015-12-31dd: summarize in --human-readable format tooPaul Eggert
Problem reported by Linda Walsh in: http://bugs.gnu.org/17505 * NEWS: Document this. * doc/coreutils.texi (dd invocation): Use a simpler script. Adjust output example to match new behavior. * src/dd.c (human_size): Remove. All uses changed to use human_readable and ... (human_opts): ... this new constant. (abbreviation_lacks_prefix): New function. (print_xfer_stats): Use it. Output both --si and --human-readable summaries, but only if they have prefixes. * tests/dd/reblock.sh, tests/dd/stats.sh: Test new behavior.
2015-11-10tests: ensure programs are built before testingPádraig Brady
programs may not be built due to missing system dependencies, or any program can be excluded at configure time with --enable-no-install-program. So ensure we're not testing the system versions in these cases. * init.cfg (print_ver_): Call require_built_ first. * tests/misc/tty-eof.pl: Skip programs not built. * tests/Coreutils.pm (run_tests): Likewise. * tests/misc/ls-misc.pl: Use 'env test' rather than abs path. * tests/misc/test-diag.pl: Likewise. * tests/local.mk: Adjust include order for dependencies. * tests/misc/arch.sh: Remove redundant calls to require_built_. * tests/misc/chroot-fail.sh: Likewise. * tests/misc/groups-dash.sh: Likewise. * tests/misc/groups-version.sh: Likewise. * tests/misc/stdbuf.sh: Likewise. * tests/cp/acl.sh: Remove problematic call to print_ver_ [gs]etfacl. * tests/mv/acl.sh: Likewise. * cfg.mk (sc_env_test_dependencies): A new syntax check to enforce specifying dependencies with print_ver_ for programs specified through the env command. * du/bigtime.sh: Add new print_ver_ dependencies. * du/max-depth.sh: Likewise. * dd/ascii.sh: Likewise. * tests/ls/capability.sh: Likewise. * tests/ls/root-rel-symlink-color.sh: Likewise. * tests/misc/chroot-fail.sh: Likewise. * tests/misc/readlink-fp-loop.sh: Likewise. * tests/misc/sort-debug-keys.sh: Likewise. * tests/readlink/can-e.sh: Likewise. * tests/readlink/can-f.sh: Likewise. * tests/readlink/can-m.sh: Likewise. * tests/tail-2/inotify-race.sh: Likewise. * tests/tail-2/inotify-race2.sh: Likewise. * tests/touch/no-create-missing.sh: Likewise. * tests/touch/no-dereference.sh: Likewise. * tests/misc/printenv.sh: Tweak to avoid syntax check trigger. * tests/misc/help-version.sh: Likewise. * tests/misc/yes.sh: Likewise. * tests/misc/printf-quote.sh: Use previously unused $prog. * configure.ac (EXTRA_MANS): Add $gl_no_install_prog to the list so that check-x-vs-1 syntax check is satisfied.
2015-11-10tests: cleanup trapping of signal namesPádraig Brady
A side effect of this cleanup is we no longer depend on our own kill command being built. * init.cfg (require_trap_signame_): A new function to verify that the shell supports specifying traps by signal name. (require_kill_group_): A new function to ensure the shell supports sending a signal to a group. * tests/du/move-dir-while-traversing.sh: Ensure trap supports signal names. * tests/misc/stty-invalid.sh: Likewise. * tests/misc/stty-pairs.sh: Likewise. * tests/misc/stty-row-col.sh: Likewise. * tests/misc/stty.sh: Likewise. * tests/misc/sort-compress.sh: Likewise. Also simplify trap call. * tests/install/trap.sh: Likewise. * tests/misc/timeout.sh: Likewise. * tests/dd/stats.sh: Likewise. Also use default kill command. * tests/misc/timeout-group.sh: Likewise.
2015-10-08tests: adjust recent changes to virtual memory limitsPádraig Brady
* tests/dd/no-allocate.sh: Account for timeout(1) when determining the required mem, as timeout has additional shared libs. This avoids the need for the hardcoded 4M addition to the limit. * tests/misc/head-c.sh: Increase the base limit, to account for the fact that head(1) will allocate some additional mem in this case. * tests/misc/cut-huge-range.sh: Remove mention of specific limits. * tests/misc/printf-surprise.sh: Likewise. Reported by Dmitry V. Levin
2015-09-22maint: use adaptive approach for `ulimit -v` based testsBernhard Voelker
When configured with either 'symlinks' or 'shebangs' as value for the --enable-single-binary option, tests based on `ulimit -v` are skipped. The reason is that the multicall 'coreutils' binary requires much more memory due to shared libraries being loaded, and the size of the 'date' binary (~290KiB) compared to the multicall binary (~5MiB), of course. Finally, in the case of 'shebangs', the starting shell requires more memory, too Instead of using hard-coded values for the memory limit, use an adaptive approach: first determine the amount of memory for a similar, yet more trivial invocation of the command, and then do the real test run using that limit (plus some buffer in some cases). * init.cfg (require_ulimit_v_): Remove function. (get_min_ulimit_v_): Add function to determine the minimum memory limit required for a given command in an adaptive way. * cfg.mk (sc_prohibit_test_ulimit_without_require_): Change the name of the above function in the syntax-check rule. * tests/cp/link-heap.sh: Use the above function to determine the minimum memory required to run a command simpler than in the real test run. Use that limit plus a buffer there. While at it, change to list of commands in the subshell to fail also if the beginning `ulimit -v` fails. * tests/dd/no-allocate.sh: Likewise. * tests/misc/csplit-heap.sh: Likewise. * tests/misc/cut-huge-range.sh: Likewise. * tests/misc/head-c.sh: Likewise. * tests/misc/printf-surprise.sh: Likewise. * tests/split/line-bytes.sh: Likewise. * tests/rm/many-dir-entries-vs-OOM.sh: Likewise - doing it separately for each program under test.
2015-07-01tests: fix false failure on slower systemsPádraig Brady
* tests/dd/stats.sh: Wait 20s for dd to write 250MB through a fifo, rather than 10s for 500MB. The failure was seen often on a lightly loaded SPARC-Enterprise-T5220 running Solaris 10.
2015-05-14tests: fix async allocation race on BTRFSPádraig Brady
* tests/dd/sparse.sh: Sync files before checking allocations, which may be done asynchronously on NFS and BTRFS at least. Also mark this test as very expensive on remote file systems. * tests/du/2g.sh: Likewise, also use fallocate if available to efficiently allocate the large file, otherwise skip on remote file systems. * tests/tail-2/inotify-rotate-resources.sh: Use the more standard is_local_dir_() to check remoteness. * tests/cp/fiemap-empty.sh: Comment on the sync issue for this currerntly unused test. Fixes http://bugs.gnu.org/20570
2015-05-11tests: cleanup background processes upon interruptionPádraig Brady
Reap background processes so that: - Stray processes aren't left on the system - Files aren't held open causing deletion issues on NFS - Partitions used to run the tests from can be unmounted * tests/tail-2/F-vs-missing.sh: Add the `kill && wait` of the background $pid(s) to cleanup_(). * tests/tail-2/F-vs-rename.sh: Likewise. * tests/tail-2/f-vs-rename.sh: Likewise. * tests/tail-2/append-only.sh: Likewise. * tests/tail-2/assert-2.sh: Likewise. * tests/tail-2/assert.sh: Likewise. * tests/tail-2/flush-initial.sh: Likewise. * tests/tail-2/inotify-hash-abuse.sh: Likewise. * tests/tail-2/inotify-hash-abuse2.sh: Likewise. * tests/tail-2/inotify-race.sh: Likewise. * tests/tail-2/inotify-rotate-resources.sh: Likewise. * tests/tail-2/inotify-rotate.sh: Likewise. * tests/tail-2/pid.sh: Likewise. * tests/tail-2/pipe-f2.sh: Likewise. * tests/tail-2/retry.sh: Likewise. * tests/tail-2/symlink.sh: Likewise. * tests/tail-2/tail-n0f.sh: Likewise. * tests/tail-2/wait.sh: Likewise. * tests/cp/existing-perm-race.sh: Likewise. * tests/cp/file-perm-race.sh: Likewise. * tests/cp/parent-perm-race.sh: Likewise. * tests/cp/sparse-to-pipe.sh: Likewise. * tests/dd/stats.sh: Likewise. * tests/du/move-dir-while-traversing.sh: Likewise. * tests/misc/cat-buf.sh: Likewise. * tests/misc/help-version.sh: Likewise. * tests/misc/printf-surprise.sh: Likewise. * tests/misc/sort-compress-proc.sh: Likewise. * tests/misc/sort-spinlock-abuse.sh: Likewise. * tests/misc/stdbuf.sh: Likewise. * tests/misc/tac-continue.sh: Likewise. * tests/misc/timeout-group.sh: Likewise. * tests/mv/i-3.sh: Likewise. * tests/rm/dangling-symlink.sh: Likewise. * tests/rm/isatty.sh: Likewise. * cfg.mk (sc_prohibit_test_background_without_cleanup_): A new syntax-check to ensure cleanup_() is defined when background tasks are created in a test.
2015-01-14tests: use compare-vs-/dev/null instead of 'test -s'Bernhard Voelker
When some program produces unexpected output, that use of compare-vs-/dev/null will ensure that the surprising output is printed in the test's output. With "test -s err" only, one would have to instrument and rerun in order to see the offending output. * cfg.mk (sc_prohibit_and_fail_1): Exempt 'compare' from this check. * tests/dd/misc.sh: Change "tests -s ... || fail=1" to "compare /dev/null ... && fail=1". * tests/misc/nice.sh: Likewise. * tests/rm/read-only.sh: Likewise. * tests/tail-2/inotify-race.sh: Likewise. * tests/touch/no-dereference.sh: Likewise. Suggested by Jim Meyering in http://lists.gnu.org/archive/html/coreutils/2015-01/msg00042.html
2015-01-14tests: add extra protection against unexpected exitsPádraig Brady
Many tests use `program ... && fail=1` to ensure expected error situations are indicated. However that would mask an unexpected exit (like a crash). Therefore explicitly check the expected exit code. Note where error messages are also verified, the extra protection is not added. * tests/init.sh (returns_): A new helper function to check the return code of a command, and used throughout the tests. * cfg.mk (sc_prohibit_and_fail_1): Add a syntax check to avoid new instances of this issue.
2015-01-01maint: update all copyright year number rangesPádraig Brady
Run "make update-copyright" and then... * tests/sample-test: Adjust to use the single most recent year. * tests/du/bind-mount-dir-cycle-v2.sh: Fix case in copyright message, so that year is updated automatically in future.
2014-11-26tests: fix portability issue in dd/ascii testPádraig Brady
Solaris 8 was seen to issue this error: "printf: `&': illegal format character" * test/dd/ascii.sh: Use the coreutils printf in this test rather than the system one, to avoid portability issues.
2014-09-30dd: new status=progress level to print stats periodicallyFederico Simoncelli
* src/dd.c: Report the transfer progress every second when the 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. * tests/dd/stats.sh: Add new test for status=progress. * tests/dd/misc.sh: Change so status=none only takes precedence if it's the last level specified. * NEWS: Mention the feature.
2014-09-30dd: use more robust SIGUSR1 handlingPádraig Brady
* src/dd.c (ifd_reopen): A new wrapper to ensure we don't exit upon receiving a SIGUSR1 in a blocking open() on a fifo for example. (iftruncate): Likewise for ftruncate(). (iread): Process signals also after a short read. (install_signal_handlers): Install SIGINFO/SIGUSR1 handler even if set to SIG_IGN, as this is what the parent can easily set from a shell script that can send SIGUSR1 without the possiblity of inadvertently killing the dd process. * doc/coreutils.texi (dd invocation): Improve the example to show robust usage wrt signal races and short reads. * tests/dd/stats.sh: A new test for various signal races. * tests/local.mk: Reference the new test. * NEWS: Mention the fix.
2014-07-14tests: fix portability issue in new dd/ascii testPádraig Brady
* tests/dd/ascii.sh: Quote so that '\\' is passed to printf rather than a single '\', as that's not portable. bash, dash, zsh and external solaris printf were seen to support printf '\%03o' 1 2 while ksh, freebsh shell and external GNU printf need the more portable printf '\\%03o' 1 2 Note we don't use env here to call the coreutils printf implementation, as there are many printf calls, so relying on portable shell implementations will be faster.
2014-07-04maint: simplify parsing df's output in shell scriptsBernhard Voelker
Avoid complicated and error-prone parsing of df's output via sed(1), cut(1), etc., and instead use df's more modern --output option. * src/ioblksize.h (in a comment): Simplify the extraction of the device name of the mounted file system from df's output. * tests/dd/skip-seek-past-dev.sh: Likewise. * tests/du/2g.sh: Likewise for the 'avail' column here. Also avoid the deprecated use of "tail -NUM". * tests/misc/stat-mount.sh: While at it, remove the determination of the mount point of "." via df(1) plus sed(1) as it is unused since commit v8.5-159-gf57cb37 anyway. Instead, improve this test by verifying that the output of "stat -c%m ." at least starts with a slash '/'.
2014-05-07tests: improve new ascii test of ddBernhard Voelker
* tests/dd/ascii.sh: Avoid unnecessary subshells. Catch dd's exit code. Remove testing artifact. In the case of a comparison failure, show the differences in octal format in addition to "binary files differ". Simplify the creation of the 'in' file.
2014-05-06dd: fix conv=ascii, conv=ebcdic, conv=ibm to match POSIXPaul Eggert
Problem reported by Don Baggett in <http:/bugs.gnu.org/17422>. * NEWS: * doc/coreutils.texi (dd invocation): Document this. * src/dd.c (conversions): conv=ascii implies conv=unblock. conv=ebcdic and conv=ibm imply conv=block. (ascii_to_ebcdic, ebcdic_to_ascii): Correct to match POSIX 1003.1-2013. * tests/dd/ascii.sh: New file. * tests/local.mk (all_tests): Add it.
2014-05-07tests: improve diagnostics when asserting empty filesPádraig Brady
* tests/chmod/c-option.sh: Use `compare /dev/null ... || fail=1` rather than `test -s ... && fail=1`, so that the file contents are output, thus improving diagnostics for failing tests. * tests/cp/acl.sh: Likewise. * tests/cp/cp-a-selinux.sh: Likewise. * tests/cp/cp-mv-enotsup-xattr.sh: Likewise. * tests/cp/reflink-perm.sh: Likewise. * tests/dd/misc.sh: Likewise. * tests/misc/env-null.sh: Likewise. * tests/misc/env.sh: Likewise. * tests/misc/nice.sh: Likewise. * tests/misc/nohup.sh: Likewise. * tests/misc/printenv.sh: Likewise. * tests/misc/xattr.sh: Likewise. * tests/mv/update.sh: Likewise. * tests/rm/deep-2.sh: Likewise. * tests/rm/read-only.sh: Likewise. * tests/split/r-chunk.sh: Likewise. * tests/tail-2/follow-stdin.sh: Likewise. * tests/tail-2/inotify-race.sh: Likewise. * tests/tail-2/wait.sh: Likewise. * tests/touch/no-dereference.sh: Likewise. * cfg.mk (sc_prohibit_test_empty:): New syntax-check. * tests/cp/proc-zero-len.sh: Adjust to avoid false syntax-check failure. * tests/cp/proc-zero-len.sh: Likewise. * tests/mv/part-symlink.sh: Likewise. * tests/tail-2/infloop-1.sh: Likewise.
2014-04-11tests: fix false dd conv=sparse failure on newer XFSPádraig Brady
* tests/dd/sparse.sh: When testing that a hole is created, use an existing sparse destination file, so that we're not write extending the file size, and thus avoiding speculative preallocation which can result in smaller holes than requested. Workaround suggested by Brian Foster
2014-01-02maint: update all copyright year number rangesBernhard Voelker
Run "make update-copyright", but then also run this, perl -pi -e 's/2\d\d\d-//' tests/sample-test to make that one script use the single most recent year number.
2013-12-13tests: avoid unlikely deadlock in dd/no-allocate on some shellsPádraig Brady
* test/dd/no-allocate.sh: Use 'wait' to ensure we don't have multiple writers to the fifo, which was seen to trigger a very hard to reproduce deadlock with make -j20 on solaris. Also avoid writing to the fifo with the shell; instead using dd. (check_dd_seek_alloc): A new function refactored from the various cases, which are now constructed from function parameters.
2013-07-19dd: make status=none suppress all diagnosticsPádraig Brady
* src/dd.c (STATUS_NONE): Simplify the enum so that it's more general than just suppressing transfer counts. Then test this in all locations where non fatal diagnostics are output. * tests/dd/misc.sh: Ensure the diagnostic about being unable to skip past the end of input is suppressed. * NEWS: Mention the change in behavior. Fixes http://bugs.gnu.org/14897
2013-04-25tests: fix usage of require_ulimit_Pádraig Brady
* init.cfg (require_ulimit_v_): Renamed from require_ulimit_ as this only checks for ulimit -v support. Other uses of ulimit -t and ulimit -n in tests shouldn't cause false failures if not supported. * cfg.mk (sc_prohibit_test_ulimit_without_require_): A new syntax check to ensure that require_ulimit_v_() is used iff required. * tests/misc/head-c.sh: Add missing call to require_ulimit_v_. * tests/rm/many-dir-entries-vs-OOM.sh: Likewise. * tests/split/r-chunk.sh: Remove non mandatory require_ulimit_ call. * tests/misc/sort-merge-fdlimit.sh: Likewise. * tests/cp/link-heap.sh: Adjust to renamed require_ulimit_v_. * tests/dd/no-allocate.sh: Likewise. * tests/misc/csplit-heap.sh: Likewise. * tests/misc/cut-huge-to-eol-range.sh: Likewise. * tests/misc/printf-surprise.sh: Likewise.
2013-04-14dd: avoid buffer allocations unless neededOndrej Oprala
* src/dd.c: Add new static global variable ibuf. (alloc_ibuf, alloc_obuf): New functions factored from dd_copy(). (dd_copy): Call the new functions to allocate memory for ibuf and obuf when necessary. (skip): Likewise. * tests/dd/no-allocate.sh: New test. * tests/local.mk: Reference the test.
2013-01-01maint: update all copyright year number rangesJim Meyering
Run "make update-copyright", but then also run this, perl -pi -e 's/2\d\d\d-//' tests/sample-test to make that one script use the single most recent year number.
2012-09-24dd: new option, status=none to suppress output statisticsPozsár Balázs
* src/dd.c (STATUS_NONE): A new bitmask combining all STATUS_ options, thus used to suppress all informational output. (struct symbol_value statuses): Expose the "none" option, corresponding to the STATUS_NONE bitmask above. (print_stats): Return early if STATUS_NONE is specified. Also move the call to gethrxtime() down so that it's only called when needed. (usage): Describe the new options. * doc/coreutils.texi (dd invocation): Likewise. * NEWS: Mention the new feature. * tests/dd/misc.sh: Ensure the new option works.
2012-09-05build: don't use recursive make for tests/ subdirectoryStefano Lattarini
* Makefile.am (SUBDIRS): Remove 'tests'. (include): The '$(top_srcdir)/tests/local.mk' file. (check-root): Remove this convenience target, it's no longer needed now that the "real" check-root target once in 'tests/Makefile' will land in the top-level makefile. * configure.ac (AC_CONFIG_FILES): Remove 'tests/Makefile'. * tests/Makefile.am: Rename ... * tests/local.mk: ... like this, with a lot of adjustments. * tests/init.cfg: Move ... * init.cfg: ... here. This is necessary, for a limitation of the gnulib-provided 'tests/init.sh', which unconditionally look for 'init.cfg' in the $(srcdir) directory. * tests/*/*.sh: Adjust: expect init.sh to be in '$srcdir/tests', not in '$srcdir', and extend $PATH with './src', not with '../src'. * tests/Coreutils.pm: Adjust similarly. * tests/pr/pr-tests.pl ($pfx): Likewise.
2012-08-30tests: add .sh and .pl suffixes to shell and perl tests, respectivelyStefano Lattarini
Not only this shrinks the size of the generated Makefile (from > 6300 lines to ~3000), but will allow further simplifications in future changes. * tests/Makefile.am (TEST_EXTENSIONS): Add '.sh' and '.pl'. (PL_LOG_COMPILER, SH_LOG_COMPILER): New, still defined simply to $(LOG_COMPILER) for the time being. (TESTS, root_tests): Adjust as described. * All tests: Rename as described.
2012-04-04tests: convert nearly all `...` expressions to $(...)Jim Meyering
Exempt init.sh because it runs before we're assured to have a shell that groks $(...). Exempt *.mk because "$" would have to be doubled, and besides, any `...` expression in a .mk file is almost certainly evaluated before init.sh is run. Finally, also exempt the perl-based tests, because perl's `...` cannot be converted to $(...). Do that by running this command: git grep -l '`.*`' tests \ | grep -Ev 'init\.sh|\.mk$' | xargs grep -Lw perl \ | xargs perl -pi -e 's/`(.*?)`/\$($1)/g' One minor fix-up change was required after that, due to how quoting differs: diff --git a/tests/chmod/equals b/tests/chmod/equals - expected_perms=$(eval 'echo \$expected_'$dest) + expected_perms=$(eval 'echo $expected_'$dest) Another was to make these required quoting adjustments: diff --git a/tests/misc/stty b/tests/misc/stty ... - rev=$(eval echo "\\\$REV_$opt") + rev=$(eval echo "\$REV_$opt") ... - rev1=$(eval echo "\\\$REV_$opt1") - rev2=$(eval echo "\\\$REV_$opt2") + rev1=$(eval echo "\$REV_$opt1") + rev2=$(eval echo "\$REV_$opt2") Also, transform two files that were needlessly excluded above: (both use perl, but are mostly bourne shell) perl -pi -e 's/`(.*?)`/\$($1)/g' \ tests/du/long-from-unreadable tests/init.cfg
2012-03-23tests: skip part of dd/sparse on some file systemsJim Meyering
* tests/dd/sparse: The last two parts of this test would fail due to the underlying file system at least on Solaris 10 with NFS. That file system would report that a 3MiB file was occupying <= 1KiB of space for nearly 50 seconds after creation. Improved-by: Bernhard Voelker
2012-03-20tests: avoid spurious dd/sparse failurePádraig Brady
* tests/dd/sparse: Allow for greater variation in sparse-block counts. Reported by Nelson H. F. Beebe and Bruno Haible.
2012-03-02tests: work around a block alignment issue in dd/sparsePádraig Brady
Prompted by the continuous integration build failure at: http://hydra.nixos.org/build/2188210 (which uses XFS). * tests/dd/sparse (alloc_equal): Add a block allocation comparison function that accounts for variations due to alignment.
2012-02-29dd: add support for the conv=sparse optionRoman Rybalko
Notes: Small seeks are not coalesced to larger ones, like is done in cache_round() for example. conv= is used rather then oflag= for FreeBSD compatibility. * src/dd.c (final_op_was_seek): A new global boolean to flag whether the final "write" was converted to a seek. (usage): Describe the new conf=sparse option. (iwrite): Convert a write of a NUL block to a seek if requested. (do_copy): Initialize the output buffer to have a sentinel, to allow for efficient testing for NUL output blocks. If the last block in the file was converted to a seek, then convert back to a write so the size is updated. * NEWS: Mention the new feature. * tests/dd/sparse: A new test for the feature. * tests/Makefile.am: Reference the new test.
2012-02-13dd: fix issues in the count_bytes and seek_bytes flags changePádraig Brady
These edge cases were missed in the previous commit 140eca15c. * src/dd.c (main): Include the bytes slop when truncating without further I/O. Don't invalidate the whole file cache in the case where 0 < count < ibs. * tests/dd/bytes: Change to using the independent truncate command to generate the file for comparison. Remove a redundant test case and replace with one testing the truncation only logic.
2012-02-12dd: add count_bytes, skip_bytes and seek_bytes flagsJérémy Compostella
dd now accepts the count_bytes and skip_bytes input flag and the seek_bytes output flag, to more easily allow processing portions of a file. * src/dd.c (scanargs): Compute skip_records and skip_bytes when 'skip_bytes' iflag is used. Compute max_records and max_bytes when 'count_bytes' iflag is used. Compute seek_records and seek_bytes when 'seek_bytes' oflag is used. (skip_via_lseek): Use new 'bytes' parameter and handle potential 'records' equals to zero. Update the bytes parameter when called with 'fdesc' equal to STDOUT_FILENO. Update the header comments. (dd_copy): Skip accordingly to skip_records AND skip_bytes. Count accordingly to max_records AND max_bytes. Seek on output accordingly to seek_records AND seek_bytes. * NEWS (New features): Mention it. * doc/coreutils.texi (dd invocation): Detail new flags and behaviors. * tests/dd/bytes: New file. Tests for these new flags. * tests/Makefile.am (TESTS): Add it.

Likewise, when an empty file is expected, use "compare /dev/null out", not "compare out /dev/null". I.e., specify the expected/desired contents via the first file name. Prompted by a suggestion from Bruno Haible in http://thread.gmane.org/gmane.comp.gnu.grep.bugs/4020/focus=29154 Run these commands: git grep -l -E 'compare [^ ]+ exp' \ |xargs perl -pi -e 's/(compare) (\S+) (exp\S*)/$1 $3 $2/' git grep -l -E 'compare [^ ]+ /dev/null' \ |xargs perl -pi -e 's/(compare) (\S+) (\/dev\/null)/$1 $3 $2/' * tests/chgrp/no-x: As above. * tests/chmod/no-x: Likewise. *

2011-08-08tests: complete the renaming framework_failure -> framework_failure_Stefano Lattarini
These changes were mostly mechanical, made by running the following command: git grep -lw framework_failure | grep -v ChangeLog \ | xargs perl -pi -e 's/\b(framework_failure)\b/${1}_/' and then editing init.cfg and `tests/cp/cp-a-selinux' by hand. * tests/init.cfg (framework_failure): Remove, `framework_failure_' from init.sh should be used instead in the tests. Remove now-obsolete "FIXME" comment. (is_local_dir_, require_strace_, require_membership_in_two_groups_, require_sparse_support_, skip_if_mcstransd_is_running_, mkfifo_or_skip_) Use `framework_failure_', not `framework_failure'. * Many test scripts: Likewise.
2011-06-17tests: remove skip_test_ function; use new skip_ insteadJim Meyering
* tests/init.cfg (skip_test_): Remove function. Use skip_ in place of skip_test_ everywhere else. * cfg.mk (sc_prohibit_skip_): Remove rule. * tests/**: Use skip_, not skip_test_, everywhere.
2011-06-13tests: avoid a false failure on HPUX systemsPádraig Brady
* tests/dd/nocache: Relax the test, as the system may return various errors from posix_fadvise(). HPUX 11.31 returns ENOTTY for example. Reported by Bruno Haible

2011-03-05maint: fix dd nocache test to be independent of current stdinPádraig Brady
* tests/dd/nocache: Don't assume stdin is a pipe
2011-03-05dd: add a flag to discard cached dataPádraig Brady
* src/dd.c (FFS_MASK): A new macro (Find First Set) refactored from the following enum as it's now used twice. (usage): Mention the new 'nocache' flag. (cache_round): A new function to help ignore requests to drop cache, that are less than page_size. (invalidate_cache): A new function to call posix_fadvise() with the appropriate offset and length. Note we don't use fdadvise() so we can detect errors when count=0. (dd_copy): Call invalidate_cache() for the portions read. (iwrite): Likewise for the portions written. (main): Call invalidate_cache for page_size slop or for full file when count=0. * cfg.mk (sc_dd_O_FLAGS): Adjust to pass. * doc/coreutils.texi (dd invocation): Describe the 'nocache' flag, and give some examples of how it can be used. * tests/dd/nocache: A new test. * tests/Makefile.am: Reference the new test. * NEWS: Mention the new feature.
