This commit implements partitioned unordered maps and makes it possible
to traverse such a map in parallel, allowing for more efficient use of
CPU resources.
The `CachedSLEs`, `TaggedCache`, and `KeyCache` classes make use of the
new functionality, which should improve performance.
* Also clean up some formatting in the Windows instructions
* Changed the recommended version for Windows to 1.1.1L after deeper
checking uncovered some build issues.
* Patch the soci unsigned-types.h file. If no changes are made, delete
the patched file and exit. If there are changes, backup the original
and replace it with the patched file.
* Fixes#3885
Patch Rocksdb only once:
* The repeated patches do not appear to affect build times, but avoiding
unnecessary copies is good for its own sake.
The existing logic involves every server sending every transaction
that it receives to all its peers (except the one that it received
a transaction from).
This commit instead uses a randomized algorithm, where a node will
randomly select peers to relay a given transaction to, caching the
list of transaction hashes that are not relayed and forwading them
to peers once every second. Peers can then determine whether there
are transactions that they have not seen and can request them from
the node which has them.
It is expected that this feature will further reduce the bandwidth
needed to operate a server.
* Add instructions to the workflow at the point where the failure would
occur, which is where someone experiencing a failure is most likely to
look. To keep things simple, the instructions are always printed. The
assumption is that if the job succeeds, nobody is likely to look
anyway.
* Provides the diff of the failure as an artifact, so the user can apply
it directly to their repo.
* Also update the levelization/README.md to clarify the levels a little
bit.
This updates the build process to use the local Artifactory server as a docker image cache to avoid being rate limited by docker hub during the build process.
While most of the code associated with secp256k1 operations had
been migrated to libsecp256k1, the deterministic key derivation
code was still using calls to OpenSSL.
If merged, this commit replaces the OpenSSL-based routines with
new libsecp256k1-based implementations. No functional change is
expected and the change should be transparent.
This commit also removes several support classes and utility
functions that wrapped or adapted various OpenSSL types that
are no longer needed.
A tip of the hat to the original author of this truly superb
library, Dr. Pieter Wuille, and to all other contributors.
The existing class offered several constructors which were mostly
unnecessary. This commit eliminates all existing constructors and
introduces a single new one, taking a `Slice`.
The internal buffer is switched from `std::vector` to `Buffer` to
save a minimum of 8 bytes (plus the buffer slack that is inherent
in `std::vector`) per SHAMapItem instance.
Add support to allow multiple indepedent nodes to produce a binary identical
shard for a given range of ledgers. The advantage is that servers can use
content-addressable storage, and can more efficiently retrieve shards by
downloading from multiple peers at once and then verifying the integrity of
a shard by cross-checking its checksum with the checksum other servers report.
* Add a new operating mode to rippled called reporting mode
* Add ETL mechanism for a reporting node to extract data from a p2p node
* Add new gRPC methods to faciliate ETL
* Use Postgres in place of SQLite in reporting mode
* Add Cassandra as a nodestore option
* Update logic of RPC handlers when running in reporting mode
* Add ability to forward RPCs to a p2p node
- Add validation/proposal reduce-relay feature negotiation to
the handshake
- Make squelch duration proportional to a number of peers that
can be squelched
- Refactor makeRequest()/makeResponse() to facilitate handshake
unit-testing
- Fix compression enable flag for inbound peer
- Fix compression algorithm parsing in the header parser
- Fix squelch duration in onMessage(TMSquelch)
This commit fixes 3624, fixes 3639 and fixes 3641
* Markdown explanation of what levelization is, the intended levels, as
well as the process used to determine dependencies
* Shell script finds all dependencies, groups them, and finds cyclic
dependencies and maps out non-cyclic dependencies.
* Github job to run the script and fail if anything changes. Should
catch introduction of new dependencies and new problems. Will also
detect changes if problems or dependencies are removed.
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.
