If you pass the --enable-coverage flag on the command line, we build our testing binaries with appropriate options eo enable coverage testing. We also build a "tor-cov" binary that has coverage enabled, for integration tests. On recent OSX versions, test coverage only works with clang, not gcc. So we warn about that. Also add a contrib/coverage script to actually run gcov with the appropriate options to generate useful .gcov files. (Thanks to automake, the .o files will not have the names that gcov expects to find.) Also, remove generated gcda and gcno files on clean.

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.
