* DBContext is just a Context This PR removes some of the specialness from the DBContext and makes it context This allows us to simplify the GetEngine code to wrap around any context in future and means that we can change our loadRepo(e Engine) functions to simply take contexts. Signed-off-by: Andrew Thornton <art27@cantab.net> * fix unit tests Signed-off-by: Andrew Thornton <art27@cantab.net> * another place that needs to set the initial context Signed-off-by: Andrew Thornton <art27@cantab.net> * avoid race Signed-off-by: Andrew Thornton <art27@cantab.net> * change attachment error Signed-off-by: Andrew Thornton <art27@cantab.net>
