* 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.

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.
* Remove DinD Service from container build template
DinD has changed how it works on GItLab due to recent docker changes such that the service no long needs to be called so long as the runner is being run on a `docker-X` tagged machine.
* refactor for docker service on normal node
When attempting to load a validator list from a configured
site, attempt to reuse the last IP that was successfully
used if that IP is still present in the DNS response.
Otherwise, randomly select an IP address from the list of
IPs provided by the DNS system.
This commit fixes#3494.
With few exceptions, servers will typically receive multiple copies
of any given message from its directly connected peers. For servers
with several peers this can impact the processing latency and force
it to do redundant work. Proposal and validation messages are often
relayed with extremely high redundancy.
This commit, if merged, introduces experimental code that attempts
to optimize the relaying of proposals and validations by allowing
servers to instruct their peers to "squelch" delivery of selected
proposals and validations. Servers making squelching decisions by
a process that evaluates the fitness and performance of a given
server and randomly selecting a subset of the best candidates.
The experimental code is presently disabled and must be explicitly
enabled by server operators that wish to test it.
Tickets are a mechanism to allow for the "out-of-order" execution of
transactions on the XRP Ledger.
This commit, if merged, reworks the existing support for tickets and
introduces support for 'ticket batching', completing the feature set
needed for tickets.
The code is gated under the newly-introduced `TicketBatch` amendment
and the `Tickets` amendment, which is not presently active on the
network, is being removed.
The specification for this change can be found at:
https://github.com/xrp-community/standards-drafts/issues/16
Commit 4dc08f8202 introduced support for
deterministic shards, which makes the sharding functionality provided
by rippled more useful.
After merging, several opportunities for further improvements to the
deterministic sharding implementation were identified and a significant
increase int memory usage during shard finalization was detected.
Because of these issues, the commit is being reverted and the feature is
being rolled back. It will be reintroduced in a future release.
* Builds Windows dependencies first.
* Builds ALL OSs in the last stage.
* Fix the MacOS builds.
* Windows dependency stages are allowed to fail so ALL configurations will
attempt to build. Windows builds will probably fail if dependencies fail
(caching may allow them to succeed), but they will at least be attempted.
* Remove broken AppVeyor config file, so it stops trying.
This change can help improve the liveness of the network during periods of network
instability, by allowing the network to track which validators are presently not online
and to disregard them for the purposes of quorum calculations.
If the 'HardenedValidations' amendment is enabled, this commit will
track the version of the software that validators embed in their
validations.
If a server notices that at least 60% of the validators on its UNL
are running a newer version than it is running, it will periodically
print an informational message, reminding the operator to check for
update.
