This adds support for a cgi /crawl request, issued over HTTPS to the configured
peer protocol port. The response to the request is a JSON object containing
the node public key, type, and IP address of each directly connected neighbor.
The IP address is suppressed unless the neighbor has requested its address
to be revealed by adding "Crawl: public" to its HTTP headers. This field is
currently set by the peer_private option in the rippled.cfg file.
Insert now blocks when the size of the memory pool exceeds a predefined
threshold. This solves the problem where sustained insertions cause the
memory pool to grow without bound.
This reverts the change that makes RocksDBQuick the default settings for
node_db "type=rocksdb". The quick settings can be obtained by setting
"type=rocksdbquick".
RocksDBQuick settings are implicated in memory over-utilization problems
seen recently.
The PeerImp::run launch function is now dispatched on the strand to prevent
undefined behavior resulting from concurrent access to the ssl::stream object.
The NuDB database backend is a high performance key/value store presented
as an alternative to RocksDB on Mac and Linux deployments, and the preferred
backend option for Windows deployments. The LevelDB backend is deprecated for
all platforms.
This includes these changes:
* 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
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
In normal operation, InboundLedgers::findCreate never returns null, but
during system shutdown, it will return null.
Since this only happens in system shutdown, when findCreate returns null
the calling function stops what it was doing and returns.
During testing, an issue where destroying the application object
and creating a new one caused problems with a static PathTable. This table
is now cleared when re-initialized.
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.
