- o Build features:
- - Tor now builds each source file in two modes: a mode that avoids
- exposing identifiers needlessly, and another mode that exposes
- more identifiers for testing. This lets the compiler do better at
- optimizing the production code, while enabling us to take more
- radical measures to let the unit tests test things.
- - The production builds no longer include functions used only
- in the unit tests; all functions exposed from a module for
- unit-testing only are now static in production builds.
- - Add an --enable-coverage configuration option to make the unit
- tests (and a new src/or/tor-cov target) to build with gcov test
- coverage support.
- o Testing:
- - We now have rudimentary function mocking support that our unit
- tests can use to test functions in isolation. Function mocking
- lets the tests temporarily replace a function's dependencies with
- stub functions, so that the tests can check the function without
- invoking the other functions it calls.
- - Add more unit tests for the <circid,channel>->circuit map, and
- the destroy-cell-tracking code to fix bug 7912.
