So i now have GOODs working semi reliably and as expected on Pharo 1.3
(squeaksource GOODS). I still don't know the root cause but I will work on it.
I will just document my problem and how i fixed it in case anyone else runs
into the same issue. I will also look at submitting the new test cases to the
GOODs on squeaksource
The root of the object database in goods is a Dictionary - pointing to various
objects including a dictionary of users for seaside.
When I would login the user into the seaside session, I would look up object
previously from the dictionary of users. I then assume that any changes to the
users would be persisted by the db commit command.
eg
establish xDict:= lookup dictionary of users from Goods
session establish connection to database
session login user using xDict to check for password etc.
change user or subobjects ---> changes to the subojects were not saved here!
session db commit --> write it all to the database.
session logout -- disconnect db.
the problem was that xDict was not linked to Goods anymore or had grown stale.
So i could make a change to user and it would save but the sub objects would
not be updated. The fix is during the session login user I need to traverse
the entire goods db to retrieve the user. Then all commits etc work. eg:
establish xDict:= lookup dictionary of users from Goods
session establish connection to database
session login user ---from xDict
tUser:= traverse Goods until you find user
save tUser (not the one found from xDict) .
change user or subobjects
session db commit --> write it all to the database.
session logout -- disconnect db.
