o Minor bugfixes (initialization):
|
||||
- Initialize the subsystems in our code in an order more closely
|
||||
corresponding to their dependencies, so that every system is
|
||||
initialized before the ones that (theoretically) depend on it.
|
||||
Fixes bug 33316; bugfix on 0.4.0.1-alpha.
|
||||
|
||||
o Minor features (tests):
|
||||
- Initialize all subsystems at the beginning of our unit test harness,
|
||||
to avoid crashes due to uninitialized subsystems.
|
||||
Follow-up from ticket 33316.
|
||||
|
||||
o Code simplification and refactoring:
|
||||
- Merge the orconn and ocirc events into the "core" subsystem, which
|
||||
manages or connections and origin circuits. Previously they
|
||||
were isolated in subsystems of their own.
