noexcept is default for destructors as of c++11. By throwing in reverselock's destructor if it's lock has been tampered with, the likely result is std::terminate being called. Indeed that happened before this change. Once reverselock has taken another lock (its ctor didn't throw), it makes no sense to try to grab or lock the parent lock. That is be broken/undefined behavior depending on the parent lock's implementation, but it shouldn't cause the reverselock to fail to re-lock when destroyed. To avoid those problems, simply swap the parent lock's contents with a dummy for the duration of the lock. That will ensure that any undefined behavior is caught at the call-site rather than the reverse lock's destruction. Barring a failed mutex unlock which would be indicative of a larger problem, the destructor should now never throw. |

Notes
The sources in this directory are unit test cases. Boost includes a unit testing framework, and since bitcoin already uses boost, it makes sense to simply use this framework rather than require developers to configure some other framework (we want as few impediments to creating unit tests as possible).
The build system is setup to compile an executable called "test_bitcoin" that runs all of the unit tests. The main source file is called test_bitcoin.cpp, which simply includes other files that contain the actual unit tests (outside of a couple required preprocessor directives). The pattern is to create one test file for each class or source file for which you want to create unit tests. The file naming convention is "<source_filename>_tests.cpp" and such files should wrap their tests in a test suite called "<source_filename>_tests". For an examples of this pattern, examine uint160_tests.cpp and uint256_tests.cpp.
Add the source files to /src/Makefile.test.include to add them to the build.
For further reading, I found the following website to be helpful in explaining how the boost unit test framework works: http://www.alittlemadness.com/2009/03/31/c-unit-testing-with-boosttest/.
test_bitcoin has some built-in command-line arguments; for example, to run just the getarg_tests verbosely:
test_bitcoin --log_level=all --run_test=getarg_tests
... or to run just the doubledash test:
test_bitcoin --run_test=getarg_tests/doubledash
Run test_bitcoin --help for the full list.
