Upgrading
=========
From 1.8.0 to 1.8.1
-------------------
1. Drop foreign keys from the "Sessions" table:
`ALTER TABLE Sessions DROP FOREIGN KEY Sessions_ibfk_1;` should work in most
cases. Otherwise, check the output of `SHOW CREATE TABLE Sessions;` and use the
foreign key name shown there.
2. Run the following MySQL statements:
----
ALTER TABLE Sessions
ADD FOREIGN KEY (UsersID) REFERENCES Users(ID) ON DELETE CASCADE;
ALTER TABLE PackageDepends
ADD FOREIGN KEY (PackageID) REFERENCES Packages(ID) ON DELETE CASCADE,
ADD FOREIGN KEY (DepPkgID) REFERENCES Packages(ID) ON DELETE CASCADE;
ALTER TABLE PackageSources
ADD FOREIGN KEY (PackageID) REFERENCES Packages(ID) ON DELETE CASCADE;
ALTER TABLE TU_VoteInfo
ADD FOREIGN KEY (SubmitterID) REFERENCES Users(ID) ON DELETE CASCADE;
ALTER TABLE TU_Votes
ADD FOREIGN KEY (VoteID) REFERENCES TU_VoteInfo(ID) ON DELETE CASCADE,
ADD FOREIGN KEY (UserID) REFERENCES Users(ID) ON DELETE CASCADE;
----
From 1.7.0 to 1.8.0
