Short-term refactoring: |
||||
Refactoring: |
||||
- SSUSession:637, SSUSession:635 get rid of casting to SSUHeader |
||||
- Identity.cpp:156 check for self asignment |
||||
|
||||
Long-term refactoring: |
||||
- Rely on a library for TLS and SSL. |
||||
- Move parsing code out of networking code, to allow better testing. |
||||
- Move streaming code to a separate directory. |
||||
- Separate front-end code (SAM, BOB, ...) from the back-end. |
||||
|
||||
|
||||
Additions: |
||||
- Write tests. |
||||
- Add documentation. |
||||
- Create a specialized IRC tunnel (instead of just a generic ClientTunnel instance). |
||||
- Ban peers with unexpected / bad behaviour. |
||||
- EdDSA support. |
||||
- Return correct error codes in HTTPProxy. |
||||
- Modify web interface layout and use AJAX to update information. |
