* common/globals.cpp, common/globals.h: Add a config flag
to control whether database code is enabled.
* server/EntityFactory.cpp, server/EntityFactory.h,
server/PersistantThingFactory.cpp, server/PersistantThingFactory.h,
server/PersistantThingFactory_impl.h, server/Persistor.cpp:
Re-work the persistence code so that persistent or non-persistent
versions of entity factories are installed at startup, removing
the need to check whether the database is enabled during
runtime.
* common/newid.cpp, server/Connection.cpp, server/server.cpp:
Replace the const that used to control whether the database
was used with the config flag.
* common/Database.cpp, common/newid.cpp, server/server.cpp:
Modify new ID checks so that code still runs when database is
unavailable, and events requiring new IDs fail cleanly.
* server/Connection.cpp: Report a failure to create a player
account if no ID available.
* rulesets/BaseMind.cpp: When processing appearance ops, handle
stamp more efficiently, report an error if ID is missing
from argument.
* server/IdlePSQLConnector.cpp, server/IdlePSQLConnector.h:
Implement re-connecting to the Database if connection is lost.
* rulesets/Character.cpp, rulesets/Entity.cpp, rulesets/Thing.cpp:
Ensure STAMP is present on appearance op args.
* server/CommListener.cpp, server/CommListener.h,
server/CommPeerListener.cpp, server/CommPeerListener.h,
server/CommSlaveListener.cpp, server/CommSlaveListener.h,
server/CommUnixListener.cpp, server/CommUnixListener.h:
Add a return value to method for creating new client socket
objects, and use it to return failure if no ID is available
from the database for a new object.
* rulesets/Py_Point3D.cpp, rulesets/Py_Vector3D.cpp,
rulesets/Python_API.cpp: Add "new" method for class wrappers, and
call the in place constructor from new rather than init. Re-write
internal function for creating new instances so it uses the "new"
method.
* rulesets/Py_Statistics.cpp: Remove some obsolete code inadvertedly
copied from another file. Comment out some unused code to get rid
of a warning.
* server/CommPSQLSocket.cpp: Clear the database connection from
destructor.
* tests/python_class.cpp: A new test for experimenting with new
Python wrappers.
* common/Database.cpp, common/Database.h, common/id.h, common/id.cpp:
Make newId() functions return the integer value.
* common/newid.cpp: Break newId out into its own file, and make
it handle whether or not the database should issue IDs.
* server/Connection.cpp, server/Persistance.cpp,
server/WorldRouter.cpp, server/server.cpp: Simply generating IDs
by just using the newId() function, and use its return value.
