Merge branch '_enh/test_backends' -- fixing inotify backend, RF backends, unittests
* _enh/test_backends: RF: reordered tests + enabled gamin now that its fix is pending in Debian ENH+BF: filtergamin -- to be more inline with current design of filterinotify ENH: 1 more sleep_4_poll to guarantee difference in time stamp ENH: few more delays for cases relying on time stamps ENH: tests much more robust now across pythons 2.4 -- 2.7 BF+RF: pyinotify refreshes watcher upon CREATE, unified/simplified *(add|del)LogPath among *Filters ENH: fail2ban-testcases -- custom logging format to ease debugging, non-0 exit code in case of failure ENH: Filter's testcases -- rename, del + list again --- a bit unstable, might still fail from time to time BF: pyinotify -- monitor the parent directory for IN_CREATE + process freshly added file (Closes gh-44) ENH: first working unittest for checking polling and inotify backends RF/BF: just use pyinotify.ThreadedNotifier thread in filterpyinotify RF: filter.py -- single readline in a loop ENH: FilterPoll -- adjusted some msgs + allowed to operate without jail (for testing) Minor additional comment to DEVELOP ENH: extended test LogfileMonitorpull/8/merge
