Hi guys,
As many of you may have noticed the command line options in Drizzle are
breaking away from using MySQL my_getopt to using
Boost::program_options. This is down to the great work by Vijay and Monty.
Unfortunately there are a couple of bugs especially in older versions of
boost which means we have had to change behaviour slightly. Any boolean
option is now switched just using the option name, a true/false or 0/1
value is not accepted. For example, in MySQL to disable InnoDB's
adaptive flushing you need to do:
--innodb_adaptive_flushing=false
In Drizzle this has now changed to:
--innodb.disable-adaptive-flushing
Two other things to note if you haven't spotted them already:
1. Option names use the formation plugin.option. So here innodb is the
plugin and disable-adaptive-flushing is the option.
2. We now only accept '-' separator, not '_'.
You should see all of this if you are using trunk now, or the release
due this week.
We do hope to eventually bring back true/false parameters once our Boost
version requirements get higher. But this could be a couple of years off.
Kind Regards
