2014-12-30tests: fix possible 8 minute running time of inotify-rotate.shPádraig Brady
Commit v8.23-63-g111a2b9 removed the expensive tag on this test, as it runs quickly on systems with inotify. However without that it would take about 8 minutes for the test to complete all iterations. * tests/tail-2/inotify-rotate.sh: Tag as expensive without inotify. Also adjust the polling parameters used on systems without inotify so that the test completes within about 15 seconds.
2014-10-30maint: tests: fix comments about retry_delay_Pádraig Brady
* tests/tail-2/F-vs-missing.sh: Comment with the correct total delay. * tests/tail-2/F-vs-rename.shi: Likewise. * tests/tail-2/flush-initial.sh: Likewise. * tests/tail-2/inotify-hash-abuse.sh: Likewise. * tests/tail-2/pipe-f2.sh: Likewise. * tests/misc/chroot-fail.sh: Initialize can_chroot_root in all cases.
2014-10-30tests: make inotify-rotate more robust and efficientPádraig Brady
* tests/tail-2/inotify-rotate.sh: Use retry_delay_ to employ an exponential backoff with a total delay of up to 25.5s. The 15s delay was seen to trigger a false failure in http://hydra.nixos.org/build/16546517 Also remove the .1s sleep in each of the 50 iterations to reduce the running time of the test and thus the expensive_ tag on this test was removed. Also ensure that we use the standard exit procedure upon failure to avoid any erroneous diagnostics due to persistent files on NFS.
2014-10-08maint: avoid syntax-check failures in previous patchPádraig Brady
* tests/misc/od-j.sh: Non standard comparison order. * tests/split/b-chunk.sh: Confusing input file name. * tests/tail-2/tail-c.sh: Redundant require ulimit.

2014-08-01tests: fix typo in tail-2/inotify-racePaul Eggert
Reported by Andreas Schwab in: http://bugs.gnu.org/18057 * tests/tail-2/inotify-race.sh (break_src): Use abs_top_srcdir, not abs_top_builddir.
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.
2014-03-05tests: avoid the :> construct which can hide errorsPádraig Brady
On most shells `:>file || framework_failure_` will not evaluate the framework_failure_ even if there was an error writing the file. shells which do evaluate the failure are ksh 93u+ and bash 4.2, while shells wich don't include bash 4.3, solaris, freebsd, dash. Furthermore this construct is problematic on Solaris 10 sh, which will try to optimize away a `:' command in a loop after the first iteration, even if it is redirected. * tests/cp/link-deref.sh: Remove the leading colon on redirections. * tests/cp/reflink-perm.sh: Likewise. * tests/id/zero.sh: Likewise. * tests/install/install-C.sh: Likewise. * tests/misc/env.sh: Likewise. * tests/misc/md5sum-bsd.sh: Likewise. * tests/misc/runcon-no-reorder.sh: Likewise. * tests/mv/partition-perm.sh: Likewise. * tests/rm/r-root.sh: Likewise. * tests/split/l-chunk.sh: Likewise. * tests/split/line-bytes.sh: Likewise. * tests/tail-2/inotify-rotate.sh: Likewise. * tests/tail-2/retry.sh: Likewise. * tests/tail-2/symlink.sh: Likewise. * tests/tail-2/wait.sh: Likewise. * tests/touch/read-only.sh: Likewise. + cfg.mk (sc_prohibit_colon_redirection): A new syntax check to avoid further instances of this creeping in.
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.
2013-12-09tests: fix false failure due to gdb inline function handlingPádraig Brady
Inline functions are awkward to breakpoint as mentioned at: https://sourceware.org/bugzilla/show_bug.cgi?id=10738 The normal case here was for the breakpoint on the inline function to fail, resulting in a 10s delay before skipping the test. However on GCC 4.7.2 on ppc64 at least it was seen that the test failed erroneously due to the breakpoint being successfully set on an "out of line" function, but an inline function was actually being called. * tests/tail-2/inotify-race.sh: Switch to a line based breakpoint, rather than a symbol base one, which avoids issues with breakpoints on inline functions. Also skip_ on the initial breakpoint check in case the breakpoint is not traversed which would be the case on remote file systems for example.
2013-12-09tail: use consistent diagnostics with and without inotifyPádraig Brady
* src/tail.c: With inotify, when a file is initially absent, we fstat(-1) for that file spec, thus recording an errnum of EBADF, which caused the "has become accessible" diagnostic to be issued, when the file first appears. Instead we avoid the fstat(-1) and thus emit the more natural and consistent "has appeared" diagnostic. * tests/tail-2/retry.sh: Use the new diagnostic which also causes this test to pass on systems without inotify.
2013-11-27tail: improve inotify handling of symlinksPádraig Brady
Previous behavior failed to read contents of a (re)appearing file, when symlinked by tail's watched file. Also we now diagnose other edge cases when running in inotify mode, where an initially missing or regular file changes to a symlink. * src/tail.c (main): If any arg is a symlink, use polling mode. (recheck): Diagnose the edge case where a symlink appears during inotify processing. * tests/tail-2/symlink.sh: Test the fix. Mention the edge cases. * tests/local.mk: Reference the new test. * NEWS: Mention the fix. Reported by: Ondrej Oprala
2013-07-22maint: make some shell and perl scripts executable in 'tests/'Bernhard Voelker
Some newer test scripts - partially ones from me - are not executable. It does not seem to be a problem, but for consistency and to avoid future problems on unusual platforms or shells change the permissions by adding the executable bit. * cfg.mk (sc_tests_executable): Add new syntax-check rule to ensure that all test scripts are executable. * tests/df/df-output.sh: Change file mode from 644 to 755. * tests/du/threshold.sh: Likewise. * tests/factor/run.sh: Likewise. * tests/init.sh: Likewise. * tests/misc/csplit-suppress-matched.pl: Likewise. * tests/misc/numfmt.pl: Likewise. * tests/tail-2/retry.sh: Likewise.
2013-06-03tests: avoid a race in tail --retry testingPádraig Brady
Prompted by the continuous integration build failure at: http://hydra.nixos.org/build/5221053 * tests/tail-2/retry.sh: Ensure the 'out' file is truncated, as it's used to arbitrate the run order of commands. Relying on the truncation in the background tail command is racy because the truncation can occur after the fork of the background shell and thus wait4lines would not wait for output to occur in 'out', which would mean that the 'missing' file could be populated by the time tail(1) gets to process it.
2013-04-20tail: exit following by descriptor when no tailable file leftBernhard Voelker
As a side effect of the previous commit which fixes 'tail -f --retry' to wait for a file to appear, tail would not exit when the last file appears untailable and gives up on this file. This can happen, for example, when the argument file name appears as directory. Tail sets the 'ignore' flag of this file to true, but instead of exiting the program, tail would continue the loop. * src/tail.c (any_live_files): Change the function to return true if any of the files is still tailable or if tail should continue to try to check again. (tail_forever): Change the condition to break the loop in the "no files remaining" case, because now any_live_files() will care about it, as mentioned above. (parse_options): When --retry is used without any follow mode, then reset reopen_inaccessible_files to false. * tests/tail-2/retry.sh: Add test case.
2013-04-20tail: let -f --retry wait for inaccessible filesBernhard Voelker
The --retry option is indeed useful for both following modes by name and by file descriptor. The difference is that in the latter case, it is effective only during the initial open. As a regression of the implementation of the inotify support, tail -f --retry would immediately exit if the given file is inaccessible. * src/tail.c (usage): Change the description of the --retry option: remove the note that this option would mainly be useful when following by name. (main): Change diagnosing dubios uses of --retry option: when the --retry option is used without following, then issue a warning that this option is ignored; when it is used together with --follow=descriptor, then issue a warning that it is only effective for the initial open. Disable inotify also in the case when the initial open in tail_file() failed (which is the actual bug fix). * init.cfg (retry_delay_): Pass excess arguments to the test function. * tests/tail-2/retry.sh: Add new tests. * tests/local.mk (all_tests): Mention it. * doc/coreutils.texi (tail invocation): Enhance the documentation of the --retry option. Clarify the difference in tail's behavior regarding the --retry option when combined with the following modes name versus descriptor. * NEWS (Bug fixes): Mention the fix. Reported by Noel Morrison in: http://lists.gnu.org/archive/html/coreutils/2013-04/msg00003.html
2013-04-04tail: exit without reading input if would never outputPádraig Brady
* src/tail.c (main): If -n0 or -c0 were specified without -f, then no data would ever be output, so exit without reading input. * tests/tail-2/tail-n0f.sh: Augment the related test with this case.
2013-02-10tests: tail-2/inotify-rotate: fix a false failure on NFSPádraig Brady
* tests/tail-2/inotify-rotate.sh: Avoid a subshell with bash, which in turn causes the `kill` to be ineffective to the tail processes (as the SIGTERM is sent to the subshell which doesn't propagate the signal on to its children). On NFS the test cleanup will then fail as there will be .nfs files maintained in the directory for the files still opened by the tail processes. Reported by Bernhard Voelker.
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.
2012-09-05build: 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

2011-11-22tests: use "compare exp out", not "compare out exp"Jim Meyering
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. *

2011-10-29tests: don't make tail's pipe-f2 test take the full 10 secondsJim Meyering
* tests/tail-2/pipe-f2: Don't always wait 10 seconds. Before, this test would always wait 10 seconds. Now, it stops early when it detects that tail -f has written output. BTW, the race condition that prompted changing the timeout from 1 second to 10 was that tail -f could be killed by the timeout before producing any output.
2011-10-12tests: avoid a false failure on systems without inotifyPádraig Brady
* tests/tail-2/follow-name: Exclude the inotify warning from the comparison. Reported by Bruno Haible.
2011-10-08tests: avoid tail-2/F-vs-missing failure on NFSJim Meyering
* tests/tail-2/F-vs-missing: This test would fail about 80% of the time on linux/powerpc when run in an NFS-mounted directory. Reported by Bruno Haible in http://thread.gmane.org/gmane.comp.gnu.coreutils.general/1726/focus=1727
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.
2011-06-11tests: inotify-rotate: avoid false positive under heavy loadJim Meyering
* tests/tail-2/inotify-rotate: Increase timeout from 10s to 40s to avoid load-induced false positive.
2011-04-25tail --follow=name no longer implies --retryJim Meyering
* src/tail.c (tail_forever_inotify): Just as without inotify, tail --follow=name now terminates when the last tailed-by-name file is unlinked or moved aside. This bug was introduced on 2009-06-15 via commit ae494d4b, "tail: use inotify if it is available". Reported by Tim Underwood in http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/22286 * NEWS (Bug fixes): Mention this. * tests/tail-2/follow-name: Test for this. * tests/Makefile.am (TESTS): Add it.
2011-04-25tests: tail-2/pipe-f2: avoid false-positive failureJim Meyering
Otherwise, this would fail (albeit rarely) on a "make -j24 check" run. * tests/tail-2/pipe-f2: Increase timeout from 1 second to 10, to avoid false positive failure.
2011-03-31tests: inotify-rotate: avoid race condition with overloaded diskJim Meyering
* tests/tail-2/inotify-rotate: Wait 50% longer for grep to succeed. Without this change, this test would fail consistently when using "make -j25 check" with F15 in a virtio- and spinning-rust-backed virtual machine.

2010-11-17tests: convert first batch of tests from test-lib.sh to init.shJim Meyering
Initially, I did this, git grep -l srcdir/test-lib.sh|xargs perl -p0i -e '~180-byte script' but that line would have been much longer than the maximum permitted by coreutils' commit hook, and wasn't readable besides, so here's a more readable version: lhs=$(printf '%s\\n' \ 'if test "$VERBOSE" = yes; then' \ ' set -x' \ ' touch --version' \ 'fi' \ '' \ '. $srcdir/test-lib.sh' \ | sed 's/\$/\\\$/g;s/touch/(\\w+)/') rhs=$(printf '%s\\n' \ '.

* src/tail.c (tail_forever_inotify): Handle the case where tail --follow=name with inotify, is not able to add a watch on a specified directory. This may happen due to inotify resource limits or if the directory is currently missing or inaccessible. In all these cases, revert to polling which will try to reopen the file later. Note inotify returns ENOSPC when it runs out of resources, and instead we report a particular error message, lest users think one of their file systems is full. (main): Document another caveat with using inotify, where we currently don't recheck directories recreated after the initial watch is setup. * tests/tail-2/F-vs-rename: Fix the endless loop triggered by the above issue. * tests/tail-2/inotify-hash-abuse: Likewise. * tests/tail-2/wait: Don't fail in the resource exhaustion case. * tests/tail-2/F-vs-missing: A new test for this failure mode which was until now just triggered on older buggy linux kernels which returned ENOSPC constantly from inotify_add_watch(). * NEWS: Mention the fix.
2010-07-05tests: make tests requiring a delay to pass, more robustPádraig Brady
* tests/init.cfg: Introduce a retry_delay_() function to repeatedly call a test function that requires a delay. This delay can now be shorter for the common case on fast systems, but will double until a configurable limit it reached before failing on slower systems. * tests/dd/reblock: Use retry_delay_. * tests/misc/cat-buf: Likewise. * tests/misc/stdbuf: Likewise. * tests/tail-2/F-vs-rename: Likewise. * tests/tail-2/flush-initial: Likewise. * tests/tail-2/tail-n0f: Likewise. * tests/tail-2/wait: Likewise. * test/dd/misc: Comment that delay is needed to trigger failure.
2010-06-30tests: fail rather than infloop in tail's inotify-rotate testJim Meyering
* tests/tail-2/inotify-rotate: Switch to new init.sh-based framework. (grep_timeout): New function. Use it in place of open-coded loops that might infloop. This was prompted by my encountering an inexplicable, and so far unreproducible, infloop in the code that was waiting for "b" to appear in "out".
2010-02-16tests: fix an unlikely race in tail-2/inotify-hash-abuse2Pádraig Brady
* tests/tail-2/inotify-hash-abuse2: Explicitly kill the process by using cleanup_() rather than using a timeout which may trigger a failure on very slow systems (< 20 iterations of the loop per second).
2010-02-02tests: fix various timeout racesPádraig Brady
Prompted by the continuous integration build failure at: http://hydra.nixos.org/build/277485 * tests/misc/timeout: Set all expected timeouts to 1s and all unexpected timeouts to 10s. In this way, tests normally proceed quickly but may delay up to 10s before reporting failures. * tests/ls/infloop: Likewise. * tests/tail-2/pid: Likewise. * tests/tail-2/pipe-f: Likewise. * tests/tail-2/wait: Likewise. * tests/dd/skip-seek-past-dev: Likewise.
2010-01-13tests: avoid spurious failures on older shellsPádraig Brady
* tests/tail-2/inotify-hash-abuse: Use kill rather than wait to determine if the tail process is still running. * tests/tail-2/inotify-hash-abuse2: Ditto.
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
2009-12-30tail: test for a bug in inotify-enabled tail -FJim Meyering
tail -F a b would stop tracking additions to b after "mv a b". * tests/tail-2/F-vs-rename: New file. * tests/Makefile.am (TESTS): Add it.
2009-12-29tail: add another test to exercise abort-inducing flaw in tail -FJim Meyering
* tests/tail-2/inotify-hash-abuse2: New test, based on a reproducer by Rob Wortman. * tests/Makefile.am (TESTS): Add it.
2009-12-29tail: add a test to exercise abort-inducing flaw in tail -FJim Meyering
* tests/tail-2/inotify-hash-abuse: New file, derived from a report by Rob Wortman. * tests/Makefile.am (TESTS): Add it. Improved by: Pádraig Brady.
2009-12-12tests: tail-without-inotify: avoid spurious test failureJim Meyering
* tests/tail-2/wait: Account for the possibility that the kernel lacks inotify support. Reported by Chris Clayton.
