[PATCH] CTDB recovery lock improvements

[Aurélien Aptel]

I have this running indefinitely and I cannot make it fail:

i=0; while ./buildtools/bin/waf test \
           --tests=samba3.blackbox.smbclient_tar'[^m]'
do
 echo "run $i ok"; sleep $((1+RANDOM%5)); ((i++))
done

The test in question (sub test_creation_reset in
source3/script/tests/test_smbclient_tarmode.pl)

1. creates several files with the archive flag
2. backup the directory in reset, which is supposed to remove the
   archive flags
3. checks that all the files from (1) are in the archive
   (and only them) and identical
4. checks that the files on the share
   have no archive flags anymore

This one does similar things:

1. creates several files with different combinations of flags (hidden,
   system, archive, read-only)
2. backups the files with certain filters (nohidden, nosystem,
   incremental)
3. checks the files in the archive according to the filters

Is using samba with CTDB introducing race conditions in flags
handling?
