When executing a shell script code "foo | bar", if "bar" terminates early, then "foo" can get I/O error when writing to stdout. The tdbtool stub did not wait to read anything from stdin when it is expected to. This would cause tests to fail randomly under load when tdbtool process exited early. Similarly, debug function read from stdin only under certain conditions (higher debug and when not reading from tty). Otherwise, exited early. Thanks to Andrew Bartlett for noticing the problem and Catalyst Cloud (http://catalyst.net.nz/cloud) for providing resources to test fixes.

This directory contains run-time support scripts for CTDB.
Selected highlights:
ctdb.init
An initscript for starting ctdbd at boot time.
events.d/
Eventscripts. See events.d/README for more details.
functions
Support functions, sourced by eventscripts and other scripts.
statd-callout
rpc.statd high-availability callout to support lock migration on
failover.
Notes:
* All of these scripts are written in POSIX Bourne shell. Please
avoid bash-isms, including the use of "local" variables (which are
not available in POSIX shell).
* Do not use absolute paths for commands. Unit tests attempt to
replace many commands with stubs and can not do this if commands are
specified with absolute paths. The functions file controls $PATH so
absolute paths should not be required.
