- txdb-factory.cpp: drop static-cache in ResolveChainDbKind so the
-chaindb flag can be toggled at runtime (needed for tests; cost is
negligible since the daemon sets it once at startup)
- txdb-rocksdb.cpp: fix ExistsRaw to honor pending-batch delete markers.
Previously a key erased inside an open batch was still reported as
existing because the underlying DB hadn't been updated yet. Mirror
ReadRaw's correct behavior: a delete marker shadows the DB value.
- chaindb_runtime_tests.cpp: per-test fresh handle via close-reopen
dance so the static g_rocksdb singleton doesn't leak state between
cases. Tests filter framework keys (length-prefixed 'version' and
'dbformat') from iterator walks. block_index test fixed to Seek()
not Seek("blockindex") since the serialized keys start with the
length byte 0x0a.
- snapshotnet_tests.cpp, chaindb_runtime_tests.cpp: include wallet.h,
ui_interface.h, uint256.h, checkpoints.h as needed for linker; add
BOOST_TEST_MODULE decl; define global stubs (pwalletMain,
uiInterface, fConfChange, etc.) so wallet.cpp link succeeds.
Result: test_snapshotnet + test_chaindb_runtime both pass with zero
errors. Found and fixed a real production bug in ExistsRaw along
the way.
The sources in this directory are unit test cases. Boost includes a unit testing framework, and since Triangles 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_triangles" that runs all of the unit tests. The main source file is called test_triangles.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. 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/
