* 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.

# Place early in the list tests of the tools that

# E.g., nearly every test script uses rm and chmod.
|
|
# help-version comes early because it's a basic sanity test.
|
|
# Put seq early, since lots of other tests use it.
|
|
# Put tests that sleep early, but not all together, so in parallel builds
|
|
# they share time with tests that burn CPU, not with others that sleep.
|
|
# Put head-elide-tail early, because it's long-running.
