[Zope-CVS] CVS: Products/Ape/lib/apelib/fs - base.py:1.3

[Shane Hathaway]

Update of /cvs-repository/Products/Ape/lib/apelib/fs
In directory cvs.zope.org:/tmp/cvs-serv23359/fs

Modified Files:
	base.py 
Log Message:
Made the standard SQL gateways static rather than dependent on a
particular database connection.  This is another step toward
simplifying the configuration of mappers.  The change involved the
following:

- Refactored the query generator to generate only one query at a
time.  Gateways no longer use it directly.  Instead, they ask the
database connection to generate a query.  The database connection
caches the generated query.

- Added a setUp method to gateways.  The setUp method can check the
interface of the connection and/or create tables.

- Consolidated the set up procedure for SQL gateways into setUp().

- Added an argument to the execute() method of SQLGatewayBase so it
can find the connection.

- Arranged for ApeStorage to call gateway.setUp().
