Hi, I was wondering what's the recommended way to initialize a "complex" twisted application. Typically, let's say I have an application which needs to create a couple of "heavy" objects, each of which may create mysql db/tables: class MyApplication(object): def __init__(self): # object1 and object2 may need to interact with MySQL, # and object2 assumes that object1 is completely initialized object1 = SomeClass1() object2 = SomeClass2() Writing this kind of code asynchronously seems very tedious. My current solution is to use non-twisted, blocking API, but there may be a more elegant solution ? My main issue with using blocking API is that I sometimes have to write the same kind of code twice (one blocking, one non blocking). cheers, David
