* Add Backend::verify API for doing consistency checks
* Add Database::close so caller can catch exceptions
* Improved Timing test for NodeStore creates a simulated workload
Unit tests that wish to spawn threads for testing concurrency may now do so
by using unit_test::thread as a replacement for std::thread. These threads
propagate unhandled exceptions to the unit test, and work with the abort on
failure feature.
This removes the old default configuration for the "rocksdb" backend and
replaces it with the configuration that was formerly available using
the experimental backend "rocksdbquick".
The new configuration setting improves the performance of the key/value
database by changing the compaction style and tuning the size parameters for
the typical rippled workload. Testing shows a decrease in I/O spikes for both
reading and writing.
An alternative to the unity build, the classic build compiles each
translation unit individually. This adds more modules to the classic build:
* Remove unity header app.h
* Add missing includes as needed
* Remove obsolete NodeStore backend code
* Add app/, core/, crypto/, json/, net/, overlay/, peerfinder/ to classic build
The SHAMap class is refactored into a separate module where each translation
unit compiles separate without errors. Dependencies on higher level business
logic are removed. SHAMap now depends only on basics, crypto, nodestore,
and protocol:
* Inject NodeStore::Database& to SHAMap
* Move sync filter instances to app/ledger/
* Move shamap to its own module
* Move FullBelowCache to shamap/
* Move private code to shamap/impl/
* Refactor SHAMap treatment of missing node handler
* Inject and use Journal for logging in SHAMap
The SConstruct is modified to provide a new family of targets, ending with
the suffix ".nounity", which compile individual translation units instead of
some of the unity translation units ("classic" builds). Two modules updated
for this treatment are ripple/basics/ and ripple/protocol/, with plans to
update more in the future. A consequence is longer build times in some cases.
A benefit of classic builds is that missing includes can be identified
through compiler errors.
Source files are split to place all unit test code into translation
units ending in .test.cpp with no other business logic in the same file,
and in directories named "test".
A new target is added to the SConstruct, invoked by:
scons count
This prints the total number of source code lines occupied by unit tests,
in rippled specific code and excluding library subtrees.
The synthetic field 'delivered_amount' can be used to determine the exact
amount delivered by a Payment without having to check the DeliveredAmount
field, if present, or the Amount field otherwise.
The field is only returned when metadata is available and the data is not
returned in binary format.
* Will use a running instance of rippled (possibly in a debugger).
* Modify all tests to respect the server_default value.
* Fail test if new account already exists and has a balance.
* README.md with instructions for advanced test debugging, particularly using no_server.
* Added new test APIs allowing easy ways to create ledgers, apply
transactions to them, close and advance them.
* Moved Ledger tests from Ledger.cpp to Ledger.test.cpp.
* Changed several TransactionEngine log priorities from lsINFO to lsDEBUG to
reduce unnecessary verbosity in the log messages while running these tests.
* Moved LedgerConsensus:applyTransactions from a private member function to a
free function so that it could be accessed externally, and without having to
reference a LedgerConsensus object. This was done to facilitate the new
testing API.
This tidies up the code that produces random numbers to conform
to programming best practices and reduce dependencies.
* Use std::random_device instead of platform-specific code
* Remove RandomNumbers class and use free functions instead
