* Peers negotiate compression via HTTP Header "X-Offer-Compression: lz4"
* Messages greater than 70 bytes and protocol type messages MANIFESTS,
ENDPOINTS, TRANSACTION, GET_LEDGER, LEDGER_DATA, GET_OBJECT,
and VALIDATORLIST are compressed
* If the compressed message is larger than the uncompressed message
then the uncompressed message is sent
* Compression flag and the compression algorithm type are included
in the message header
* Only LZ4 block compression is currently supported
* 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
* Whenever a node downloads a new VL, send it to all peers that
haven't already sent or received it. It also saves it to the
database_dir as a Json text file named "cache." plus the public key of
the list signer. Any files that exist for public keys provided in
[validator_list_keys] will be loaded and processed if any download
from [validator_list_sites] fails or no [validator_list_sites] are
configured.
* Whenever a node receives a broadcast VL message, it treats it as if
it had downloaded it on it's own, broadcasting to other peers as
described above.
* Because nodes normally download the VL once every 5 minutes, a single
node downloading a VL with an updated sequence number could
potentially propagate across a large part of a well-connected network
before any other nodes attempt to download, decreasing the amount of
time that different parts of the network are using different VLs.
* Send all of our current valid VLs to new peers on connection.
This is probably the "noisiest" part of this change, but will give
poorly connected or poorly networked nodes the best chance of syncing
quickly. Nodes which have no http(s) access configured or available
can get a VL with no extra effort.
* Requests on the peer port to the /vl/<pubkey> endpoint will return
that VL in the same JSON format as is used to download now, IF the
node trusts and has a valid instance of that VL.
* Upgrade protocol version to 2.1. VLs will only be sent to 2.1 and
higher nodes.
* Resolves#2953
This commit restructures the HTTP based protocol negotiation that `rippled`
executes and introduces support for negotiation of compression for peer
links which, if implemented, should result in significant bandwidth savings
for some server roles.
This commit also introduces the new `[network_id]` configuration option
that administrators can use to specify which network the server is part of
and intends to join. This makes it possible for servers from different
networks to drop the link early.
The changeset also improves the log messages generated when negotiation
of a peer link upgrade fails. In the past, no useful information would
be logged, making it more difficult for admins to troubleshoot errors.
This commit also fixes RIPD-237 and RIPD-451
* replace boost::beast::detail::iequals with boost::iequals
* replace deprecated `buffers` function with `make_printable`
* replace boost::beast::detail::ascii_tolower with lambda
* add missing includes
This commit allows server operators to reserve slots for specific
peers (identified by the peer's public node identity) and to make
changes to the reservations while the server is operating.
This commit closes#2938
* Add construction and assignment from a generic
contiguous container. Both compile-time and run time
safety checks are made to ensure the safety of this
conversion.
* Remove base_uint::copyFrom. The generic copy assignment
operator now does this functionality with enhanced
safety and better syntax.
* Remove construction from and dedendence on Blob.
The generic constructor and assignment now handle this
functionality.
* Fix client code to adhere to this new API.
* Removed the use of fromVoid in PeerImp.cpp as it was
an inappropriate use of this dangerous API. The
generic container constructors do it with enhanced
safety and better syntax.
* Rename data member pn to data_ and make it private.
* Remove constraint from hash_append
* Remove array_type alias
This patch removes calls to several deprecated asio functions.
* `io_service::post` becomes `post` (free function)
* `io_service::work` becomes `executor_work_guard`
* `io_service::wrap` becomes `bind_executor`
* `get_io_context` becomes `get_executor` or `get_executor().context()`
This patch was tested with boost 1.69 and 1.70. The functions
`ripple::get_lowest_layer` and `beast::create_waitable_timer` are required to
handle a breaking difference between these versions. When rippled no longer
needs to support pre 1.70 boost versions, both of these functions may be
removed, and the waitable timer injections may also be removed.
When validators publish a proposal, they include the close time that they
believe the new ledger should have, and the network attempts to reach
consensus on that.
Instead of delaying consensus if no close time has the required majority
the servers can "agree to disagree"; if this happens, they switch to
proposing a close time of 0, and the network avalanches to that value.
If that occurs, determinstic rules record the new ledger's close time as
being one second later than its parent, and set a flag indicating that
no consensus on the close time was reached.
The wire protocol decoder would incorrectly filter such proposals, so
that they would not be seen by the higher level consensus engine.
This commit removes the low-level filtering, and allows higher level
code to filter out stale proposals instead.
Fixes: RIPD-1574
Alias beast address classes to the asio equivalents. Adjust users of
address classes accordingly. Fix resolver class so that it can support
ipv6 addresses. Make unit tests use ipv6 localhost network. Extend
endpoint peer message to support string endpoint
representations while also supporting the existing fields (both are
optional/repeated types). Expand test for Livecache and Endpoint.
Workaround some false positive ipaddr tests on windows (asio bug?)
Replaced usage of address::from_string(deprecated) with free function
make_address. Identified a remaining use of v4 address type and
replaced with the more appropriate IPEndpoint type (rpc_ip cmdline
option). Add CLI flag for using ipv4 with unit tests.
Release Notes
-------------
The optional rpc_port command line flag is deprecated. The rpc_ip
parameter now works as documented and accepts ip and port combined.
* UptimeClock is a chrono-compatible seconds-precision clock.
* Like UptimeTimer, its purpose is to make it possible for clients
to query the uptime thousands of times per second without a
significant performance hit.
* UptimeClock decouples itself from LoadManager by managing its
own once-per-second update loop.
* Clients now traffic in chrono time_points and durations instead
of int.
* RIPD-1617, RIPD-1619, RIPD-1621:
Verify serialized public keys more strictly before
using them.
* RIPD-1618:
* Simplify the base58 decoder logic.
* Reduce the complexity of the base58 encoder and
eliminate a potential out-of-bounds memory access.
* Improve type safety by using an `enum class` to
enforce strict type checking for token types.
* RIPD-1616:
Avoid calling `memcpy` with a null pointer even if the
size is specified as zero, since it results in undefined
behavior.

Do not process a transaction received from a peer if it has
been processed within the past ten seconds.
Increase the number of transaction handlers that can be in
flight in the job queue and decrease the relative cost for
peers to share transaction and ledger data.
Additionally, make better use of resources by adjusting the
number of threads we initialize, by reverting commit
68b8ffdb63.
Performance counter modifications:
* Create and display counters to track:
1) Pending transaction limit overruns.
2) Total peer disconnections.
3) Peers disconnections due to resource consumption.
Avoid a potential double-free in Json library.
Do not dispatch a transaction received from a peer for
processing, if it has already been dispatched within the
past ten seconds.

It is common for a validator operator to connect their validator
only to other nodes under their control, using clustering. Relaying of
untrusted validations and proposals must be unreliable to prevent
denial of service attacks. But currently, they are unreliable even
within a cluster.
With this change, a cluster member's decisison to relay (or originate)
a validation or proposal is honored by other cluster members. This
ensures that validators in a cluster will get reliable relaying to
hubs outside the cluster, even if other members of the cluster do not
have that validator on their UNL.
