2015-05-11tail: consistently output all data for truncated filesPádraig Brady
Generally if logs are truncated, they're truncated to 0 length, so output all existing data when our heuristic determines truncation. Note with inotify, truncate() and write() are often determined independently and so all data would be written if that was the case. * src/tail.c (check_fspec): Reset file offset to 0 upon truncation. (tail_forever): Likewise. (recheck): Add a FIXME for the related issue where tail may lose data due to tail discounting older log files too early. * tests/tail-2/truncate.sh: A new test. * tests/local.mk: Reference the new test. * NEWS: Mention the fix.
2015-05-11tail: fix inotify startup racesPádraig Brady
The previous fixes to races in the various tail tests, identified actual races in the tail inotify implementation. With --follow=descriptor, if the tailed file was replaced before the inotify watch was added, then any subsequent changes were ignored. Similarly in --follow=name mode, all changes to a new name were effectively ignored if that name was created after the original open() but before the inotify_add_watch(). * src/tail.c (tail_forever_inotify): Fix 3 cases. 1. With -f, don't stop tailing when file removed before watch. 2. With -f, watch right file when file replaced before watch. 3. With -F, inspect correct file when replaced before watch. Existing tests identify these when tail compiled with TAIL_TEST_SLEEP. * tests/tail-2/inotify-rotate-resources.sh: This test also identifies the issue with --follow=name when TAIL_TEST_SLEEP is used. Adjust so the test is immune to such races, and also fail quicker on remote file systems. * tests/tail-2/inotify-race2.sh: A new test using GDB, based on inotify-race.sh, which tests the -F race without needed recompilation with sleeps. * tests/local.mk: Reference the new test. * NEWS: Mention the bug.
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.
2015-05-11tests: avoid hung processes due to gdb SIGCONT handlingPádraig Brady
* tests/tail-2/inotify-race.sh: Add a `wait` to ensure that we reap all background gdb and tail processes. That resulted in the test hanging intermittently and upon investigation was due to gdb intermittently failing to terminate the child process due to receiving a SIGCONT signal. Therefore we avoid using timeout(1) which sends that signal, and instead rely on tail's inbuilt --pid monitoring on a background sleep process. Given this new implementation, the VERY_EXPENSIVE guard was removed. Related issues with this test hanging were previously discussed at: https://lists.gnu.org/archive/html/bug-coreutils/2009-12/msg00025.html
2015-05-11tests: fix races in and standardize the tail testsPádraig Brady
* tests/tail-2/F-vs-missing.sh: Use standard "fastpoll" options (-s.1 --max-unchanged-stats=1) to speedup the non-inotify case. Add the non-inotify case to the test. `wait` on the background tail process to terminate which should avoid the need for the non standard `retry_delay_ cleanup ...` on NFS. * tests/tail-2/F-vs-rename.sh: Remove 'out' at the start of the loop, to avoid a race in checking its contents. Also ensure 'a' & 'b' files are present before the tail process starts. Use the standard "fastpoll" options as above. * tests/tail-2/f-vs-rename.sh: Likewise. * tests/tail-2/append-only.sh: Use more standard variable names. * tests/tail-2/flush-initial.sh: Use "fastpoll" options for non-inotify platforms. Also `wait` on the background tail to avoid stray processes and file cleanup issues on NFS. * tests/tail-2/inotify-hash-abuse.sh: Always run non-inotify case. Use "fastpoll" options. Use a more standard retry_delay_ instead of a hardcoded sleep loop. Add a `wait` on the background tail. * tests/tail-2/inotify-hash-abuse2.sh: Likewise. * tests/tail-2/inotify-rotate-resources.sh: Wait just on the specific tail $pid needed. * tests/tail-2/inotify-rotate.sh: Use "fastpoll" options. * tests/tail-2/pid.sh: Use standard variable names. Add a `wait` on the background tails. * tests/tail-2/pipe-f2.sh: Likewise. * tests/tail-2/tail-n0f.sh: Likewise. * tests/tail-2/retry.sh: Use "fastpoll" options. * tests/tail-2/symlink.sh: Likewise. * tests/tail-2/wait.sh: Likewise. Speedup by using sub second parameters to timeout(1). Improve the part ensuring that -F never follows a renamed file. * tests/tail-2/infloop-1.sh: Remove invalid test. tail(1) was not being passed the --pid=$yes_pid option, retry_delay_ wasn't used to avoid races, and yes could write huge files before being killed. * tests/local.mk: Remove the invalid test reference. * tests/tail-2/assert-2.sh: Rewrite using retry_delay_(). Since no longer hardcoding large delays, remove the VERY_EXPENSIVE tag. * tests/tail-2/assert.sh: Likewise.
2015-03-31tail: fix -f to follow changes after a renameStephane Chazelas
* src/tail.c (tail_forever_inotify): Only monitor write()s and truncate()s to files in --follow=descriptor mode, thus avoiding the bug where we removed the watch on renamed files. Also adjust the inotify event processing code that is now significant only in --follow=name mode. * tests/tail-2/F-vs-rename.sh: Improve this existing test by running in both polling and inotify modes. * tests/tail-2/f-vs-rename.sh: A new test based on the existing one. * tests/local.mk: Reference the new test. * NEWS: Mention the bug. Fixes http://bugs.gnu.org/19760
2015-02-06tail: return inotify resources where possiblePádraig Brady
Each user has a maximum number of inotify watches, so handle the cases where we exhaust these resources. * src/tail.c (tail_forever_inotify): Ensure we inotify_rm_watch() the watch for an inode, when replacing with a new watch for a name. Return all used inotify resources when reverting to polling. Revert to polling upon first indication of inotify resource exhaustion. Revert to polling on any inotify resource exhaustion. Diagnose resource exhaustion correctly in all cases. Avoid redundant reinsertion in the hash for unchanged watches (where only attributes of the file are changed). * tests/tail-2/retry.sh: Avoid false failure when reverting to polling. * tests/tail-2/inotify-rotate.sh: Likewise. * tests/tail-2/symlink.sh: Likewise. * tests/tail-2/inotify-rotate-resources.sh: New test to check that we're calling inotify_rm_watch() for replaced files. * tests/local.mk: Reference the new test. * NEWS: Mention the bug fix. * THANKS.in: Thanks for reporting and problem identification.
2015-02-06tests: fix recent regression in tail inotify testPádraig Brady
* tests/tail-2/inotify-rotate.sh (cleanup_fail_): Set fail=1 so that failures are identified. Regression in v8.23-63-g111a2b9 Also use print_ver_ rather than open coding --verbose support. Also check for more than a single 'b' which seems brittle.
2015-01-31doc,maint: fix use of "i.e." in documentation and commentsBernhard Voelker
To align with all other places (and correct grammar), change all upper-case "I.E." to "I.e.". Furthermore, ensure that "i.e." is followed by a comma. Finally, ensure to use a double-space before "I.e.," at the beginning of a sentence. The following was used to change all offending uses (apart from old ChangeLog files): $ git grep -liF 'i.e.' \ | xargs sed -i \ -e 's/I\.E\./I.e./g' \ -e 's/\. \(I\.e\.\)/. \1/g' \ -e 's/\([Ii]\.e\.\)\( \)/\1,\2/g' \ -e 's/\([Ii]\.e\.\)$/\1,/g' * cfg.mk (sc_prohibit_uppercase_id_est): Add new rule. (sc_ensure_double_space_after_dot_before_id_est): Likewise. (sc_ensure_comma_after_id_est): Likewise. (old_NEWS_hash): Refresh hash via "make update-NEWS-hash". * NEWS: Change use of "id est" abbreviation via the above command. * README: Likewise. * README-prereq: Likewise. * doc/coreutils.texi: Likewise. * gl/lib/rand-isaac.c: Likewise. * gl/lib/tempname.c.diff: Likewise. * man/stdbuf.x: Likewise. * src/cat.c: Likewise. * src/copy.c: Likewise. * src/copy.h: Likewise. * src/cp.c: Likewise. * src/cut.c: Likewise. * src/dd.c: Likewise. * src/df.c: Likewise. * src/fiemap.h: Likewise. * src/longlong.h: Likewise. * src/ls.c: Likewise. * src/numfmt.c: Likewise. * src/pr.c: Likewise. * src/shred.c: Likewise. * src/shuf.c: Likewise. * src/split.c: Likewise. * tests/Coreutils.pm: Likewise. * tests/df/df-symlink.sh: Likewise. * tests/df/skip-rootfs.sh: Likewise. * tests/init.sh: Likewise. * tests/ls/color-norm.sh: Likewise. * tests/misc/basename.pl: Likewise. * tests/misc/ls-misc.pl: Likewise. * tests/misc/md5sum-bsd.sh: Likewise. * tests/misc/shred-exact.sh: Likewise. * tests/misc/sort.pl: Likewise. * tests/misc/stdbuf.sh: Likewise. * tests/misc/tac-continue.sh: Likewise. * tests/rm/r-root.sh: Likewise. * tests/tail-2/symlink.sh: Likewise.
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
2015-01-01maint: 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.
2014-12-30tests: 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.
2014-10-07wc: don't miscount /sys and similar file systemsPaul Eggert
Fix similar problems in head, od, split, tac, and tail. Reported by George Shuklin in: http://bugs.gnu.org/18621 * NEWS: Document this. * src/head.c (elseek): Move up. (elide_tail_bytes_pipe, elide_tail_lines_pipe): New arg CURRENT_POS. All uses changed. (elide_tail_bytes_file, elide_tail_lines_file): New arg ST and remove arg SIZE. All uses changed. * src/head.c (elide_tail_bytes_file): * src/od.c (skip): Avoid optimization for /sys files, where st_size is bogus and st_size == st_blksize. Don't report error at EOF when not optimizing. * src/head.c, src/od.c, src/tail.c: Include "stat-size.h". * src/split.c (input_file_size): New function.

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

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

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.

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: substitute the single-program $VERBOSE/--version usesJim Meyering
Automatically make all of the changes like this: -test "$VERBOSE" = yes && chgrp --version +print_ver_ chgrp git grep -l 'VERBOSE.*--version'|xargs perl -pi -e \ 's/test "\$VERBOSE" = yes && (\w+) --version/print_ver_ $1/'
2010-11-17tests: convert first batch of tests from test-lib.sh to init.shJim Meyering
Initially, I did this, git grep -l srcdir/test-lib.sh|xargs perl -p0i -e '~180-byte script' but that line would have been much longer than the maximum permitted by coreutils' commit hook, and wasn't readable besides, so here's a more readable version: lhs=$(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' \ '. "${srcdir=.}/init.sh"; path_prepend_ ../src' \ 'test "$VERBOSE" = yes && FIXME --version' \ | sed 's/\$/\\\$/g;s/FIXME/\$1/') git grep -l srcdir/test-lib.sh|xargs perl -p0i -e "s,$lhs,$rhs,"
