Was just working on a config today. Part of it was "create a database w/ its tables, add some stored procedures, import a development snapshot dump" but only if this wasn't already done (obviously). How do you do that in a convergent fashion? So: 1. Create database 2. Import schema 3. Import stored procedures 4. Import a dump All of these only if necessary. I can see handling #1 -- just check if the database exists. #2 dito, #3 would be a bit more hard but I guess dito. #4 is the troublesome thing. How do I know if "the dump has been imported" in a clean fashion? Check if there is "some data" in the DB? What if it was partially applied? etc. I think using a flag file sounds fine. Yes, if it's deleted then re-running the script should bring it back to an expected state, not break it. But yes, the flag file sounds good to prevent starting a long-running script, or something. What's your take? Is cfengine the wrong tool to import the dump? This, btw, is for provisioning a devel workstation. _______________________________________________ Help-cfengine mailing list Help-cfengine@cfengine.org https://cfengine.org/mailman/listinfo/help-cfengine
