This commit combines a number of cleanups, targeting both the
code structure and the code logic. Large changes include:
- Using more strongly-typed classes for SHAMap nodes, instead of relying
on runtime-time detection of class types. This change saves 16 bytes
of memory per node.
- Improving the interface of SHAMap::addGiveItem and SHAMap::addItem to
avoid the need for passing two bool arguments.
- Documenting the "copy-on-write" semantics that SHAMap uses to
efficiently track changes in individual nodes.
- Removing unused code and simplifying several APIs.
- Improving function naming.
- Simplify and consolidate code for parsing hex input.
- Replace beast::endian::order with boost::endian::order.
- Simplify CountedObject code.
- Remove pre-C++17 workarounds in favor of C++17 based solutions.
- Improve `base_uint` and simplify its hex-parsing interface by
consolidating the `SexHex` and `SetHexExact` methods into one
API: `parseHex` which forces callers to verify the result of
the operation; as a result some public-facing API endpoints
may now return errors when passed values that were previously
accepted.
- Remove the simple fallback implementations of SHA2 and RIPEMD
introduced to reduce our dependency on OpenSSL. The code is
slow and rarely, if ever, exercised and we rely on OpenSSL
functionality for Boost.ASIO as well.
- Provide separate functions for serializing depending on whether
one wants a "wire" version of a node, or one suitable for hashing.
- Remove unused functions
This commit introduces no functional changes but cleans up the
code and shrinks the surface area by removing dead and unused
code, leveraging std:: alternatives to hand-rolled code and
improving comments and documentation.
* Reduce lock scope on all public functions
* Use TaskQueue to process shard finalization in separate thread
* Store shard last ledger hash and other info in backend
* Use temp SQLite DB versus control file when acquiring
* Remove boost serialization from cmake files
At this point all of the jss::* names are defined in the same
file. That file has been named JsonFields.h. That file name
has little to do with either JsonStaticStrings (which is what
jss is short for) or with jss. The file is renamed to jss.h
so the file name better reflects what the file contains.
All includes of that file are fixed. A few include order
issues are tidied up along the way.
The ledger_request RPC call, under some conditions, did not
actually check that the entire ledger was present in the
database, making it unsuitable for use in cases where the
database was believed to be incorrect or incomplete.
With this change, the full ledger will be checked for
integrity unless it has already recently been checked
(according to the InboundLedgers cache).
Replace the sparsely used strCopy function with Slice. Change some of
the SHAMap interface to use Slice instead of Blob, which should
eliminate a copy.
Replace Journal public data members with member function accessors
in order to make Journal lighter weight. The change makes a
Journal cheaper to pass by value.
Also add missing stream checks (e.g., calls to JLOG) to avoid
text processing that ultimately will not be stored in the log.
* Remove cxx14 compatibility layer from ripple
* Update travis to clang 3.6 and drop gcc 4.8
* Remove unneeded beast CXX14 defines
* Do not run clang build with gdb with travis
* Update circle ci to clang 3.6 & gcc-5
* Don't run rippled in gdb, clang builds crash gdb
* Staticly link libstdc++, boost, ssl, & protobuf
* Support builds on ubuntu 15.10
* Track stats for ledger fetch and output
* Reduce entries queried on timeout
* Allow duplicate node requests on timeout
* Don't query deep on timeout
* Adjust latency tuning
* Change high latency cutoff
* Set absolute limit on reply entries
* Small optimizations
* Remove ripple::RippleMutex and ripple::RippleRecursiveMutex
and use std::mutex and std::recursive_mutex respectively.
* Use std::lock_guard instead of std::unique_lock when the
additional features of std::unique_lock are not needed.
* This reduces the memory requirements of both leaf and inner nodes.
* The name SHAMapTreeNode is retained for leaf nodes so as to keep
the public API of SHAMap stable.
In InboundLedgers::acquire, properly return a ledger if we are
able to create one immediately.
In LedgerMaster::walkHashBySeq, don't walk the whole ledger if
we already know we have it.
* Inject dependencies, make functions free and levelize
* Add comments to document the intent behind the code
* Reduce class public interfaces
* Remove support for proposals without ledger hashes
