2015-05-17build: avoid issues with case insensitive file systemsPádraig Brady
* cfg.mk (sc_case_insensitive_file_names): A new syntax-check rule. * tests/tail-2/descriptor-vs-rename.sh: Rename from tests/tail-2/f-vs-rename.sh * tests/local.mk: Reference the renamed test. Reported by Jim Meyering.
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: 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.
