Re: [Refdb-devel] refdb db in menu?

[Michael S. <sm...@xm...>]

hmm, I realize now that naming the base db "refdb" is arbitrary. I guess
a user could choose during install to call the base database "mybasedb"
or whatever, and then could create another database called "refdb", and
have references added to that.

Maybe I could make it configurable through a variable named
say, refdb-base-database. (In addition to the current
refdb-listdb-sql-regexp variable).

The code would take the list of databases that listdb returns, check it
against refdb-base-database, and remove any whatever name matches.  I
could make "refdb" the default, and document it by saying:

  Set this to whatever name you gave to the base RefDB database during
  installation (that is, using 'mysql -e "CREATE DATABASE refdb1"' or
  the PostgreSQL "createdb" command).

Or to make it more configurable, we could add refdb-listdb-ignore-list
variable, again with default value "refdb", but make it a list. Users
could put multiple names into it that way, and then wouldn't need to
mess around with trying to figure out how to construct a regex and
express it in whatever syntax their backend database supported.

And that way, we could also include the built-in database names for the
backends -- i.e. Postgres's "template0" and "template1" databases, and
whatever the names are of the built-in databases that MySQL sets up.

How does that sound?

Now that I write all that, though, I wonder whether that logic might not
be better handled on the RefDB side -- so that refdbd -C listdb wouldn't
return the name of the base RefDB database, whatever its name, or of the
built-in backend database names.
