NuDB is a high performance key/value database optimized for insert-only
workloads, with these features:
* Low memory footprint
* Values are immutable
* Value sizes from 1 2^48 bytes (281TB)
* All keys are the same size
* Performance independent of growth
* Optimized for concurrent fetch
* Key file can be rebuilt if needed
* Inserts are atomic and consistent
* Data file may be iterated, index rebuilt.
* Key and data files may be on different volumes
* Hardened against algorithmic complexity attacks
* Header-only, nothing to build or link
This changes expect and unexpected to receive the reason text as a
template argument, allowing the std::string conversion of char const*
parameters to take place only if the condition evaluates to false. This
cuts all calls to malloc and free on tests that pass.
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.
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
* Fix to_string conversion
* Fix assert on debug invariant checks
* Fix the treatment of the output position when the entire output is committed.
* Add unit test
The abstract_clock is now templated on a type meeting the requirements of
the Clock concept. It inherits the nested types of the Clock on which it
is based. This resolves a problem with the original design which broke the
type-safety of time_point from different abstract clocks.
This transforms a ConstBufferSequence into a new ConstBufferSequence whose
data is encoded according to the Content transfer encoding rules of RFC2616.
The implementation does not copy any memory.
* Use signal_set as cross platform way of handling SIGINT
* Remove polling on main thread for shutdown.
* Add extra logging for received signal.
* Clean up exit handling on error in setup routines.
* Reuse isStopped() from Stoppable for status (could be isStopping() instead).
* Ctrl-C should now work for standalone mode as well on Windows.
Also small fixes to Resolver:
* Add Resolver prefix to logging.
* Fix AsyncObject::removeReference() logic.
* Fix work remaining logic.
* New src/ripple/crypto and src/ripple/protocol directories
* Merged src/ripple/common into src/ripple/basics
* Move resource/api files up a level
* Add headers for "include what you use"
* Normalized include guards
* Renamed to JsonFields.h
* Remove obsolete files
* Remove net.h unity header
* Remove resource.h unity header
* Removed some deprecated unity includes
The Stoppable interface aids in the enforcement of invariants needed to
successful start and stop a multi-threaded application composed of classes
that depend on each other in complex ways.
* Test written to confirm the current behavior.
* Comments updated to reflect the current behavior.
* Public API reduced to what is currently in use.
* Protected data members made private.
* volatile bool members changed to std::atomic<bool>.
* std::atomic<int> members changed to std::atomic<bool>.
* Name storage uses std::string
This gives the ssl_bundle shared ownership of the underlying ssl context
so that ownership of the bundle may be transferred to other classes without
introduce lifetime issues.
