* Remove Application & Database dependency in PerfLog. Replace it with
a callback passed into the constructor.
* Fixes the circular dependency between ripple/nodestore and ripple/basics
- Only duplicate records from archive to writable during online_delete.
- Log duration of nodestore reads.
- Include nodestore counters in perf_log output.
- Remove gratuitous nodestore activity counting.
- Report initial sync duration in server_info and perfLog.
- Report state_accounting in perfLog.
- Make state_accounting durations more accurate.
- Parallel ledger loader.
- Config parameter to load ledgers on start.
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.
The following changes were made:
- Removed dependency on template defined in beast detail namespace.
- Removed Section::find() method which had an obsolete interface.
- Made Section::get<>() easier to use for the common case of
retrieving a std::string. The revised get() method replaces old
calls to Section::find().
- Provided a default template parameter to free function
get<>(Section config, std::string name) so it stays similar to
Section::get<>().
Then the rest of the code was adapted to these changes.
- Calls to Section::find() were replaced with calls to Section::get.
- Unnecessary get<std::string>() arguments were reduced to get().
These changes dug up an interesting artifact in the SHAMap unit
tests. I'm not sure why the tests were working before, but there
was a problem with the case of a Section key. The unit test is
fixed.
In order to effectively mitigate CVE-2021-3499 even when compiling
against versions of OpenSSL prior to 1.1.1k, this commit:
1) requires use of TLS 1.2 or later. Note that both TLS 1.0 and
TLS 1.1 have been officially deprecated for over a year.
2) disables renegotiation support for TLS 1.2 connections.
Lastly, this commit also changes the default list of ciphers that
the server offers, limiting it only to ciphers that are part of
TLS 1.2.
- 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.
This commit introduces a new configuration option that server
operators can set. The value is communicated to other servers
and is also reported via the `server_info` API.
The value is meant to allow third-party applications or tools
to group servers together. For example, a tool that visualizes
the network's topology can group servers together.
Similar to the "Domain" field in validator manifests, an operator
can claim any domain. Prior to relying on the value returned, the
domain should be verified by retrieving the xrp-ledger.toml file
from the domain and looking for the server's public key in the
`nodes` array.
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.
* Make sure variables are always initialized
* Use lround instead of adding .5 and casting
* Remove some unneeded vars
* Check for null before calling strcmp
* Remove redundant if conditions
* Remove make_TxQ factory function
In deciding whether to relay a proposal or validation, a server would
consider whether it was issued by a validator on that server's UNL.
While both trusted proposals and validations were always relayed,
the code prioritized relaying of untrusted proposals over untrusted
validations. While not technically incorrect, validations are
generally more "valuable" because they are required during the
consensus process, whereas proposals are not, strictly, required.
The commit introduces two new configuration options, allowing server
operators to fine-tune the relaying behavior:
The `[relay_proposals]` option controls the relaying behavior for
proposals received by this server. It has two settings: "trusted"
and "all" and the default is "trusted".
The `[relay_validations]` options controls the relaying behavior for
validations received by this server. It has two settings: "trusted"
and "all" and the default is "all".
This change does not require an amendment as it does not affect
transaction processing.
The built-in watchdog is simplistic and can, sometimes, cause problems
especially on systems that have the ability to automatically start and
monitor processes.
This commit removes the sustain system entirely, changes the handling
of the SIGTERM signal to properly terminate the process and improves
the error message reported to the user when the command line used to
start `rippled` is incorrect and malformed.
This commit removes obsolete comments, dead or no longer useful
code, and workarounds for several issues that were present in older
compilers that we no longer support.
Specifically:
- It improves the transaction metadata handling class, simplifying
its use and making it less error-prone.
- It reduces the footprint of the Serializer class by consolidating
code and leveraging templates.
- It cleanups the ST* class hierarchy, removing dead code, improving
and consolidating code to reduce complexity and code duplication.
- It shores up the handling of currency codes and the conversation
between 160-bit currency codes and their string representation.
- It migrates beast::secure_erase to the ripple namespace and uses
a call to OpenSSL_cleanse instead of the custom implementation.
Existing per-thread PRNGs are individually initialized using calls
to std::random_device.
If merged, this commit will use a single PRNG, initialized from
std::random_device on startup, to seed the thread-specific PRNGs.

* canonicalize_replace_cache
* canonicalize_replace_client
Now it is clear at the call site that if there are
duplicate copies of the data between the cache and
the caller, which copy gets replaced.
Additionally data parameter is now const-correct.
If it is not going to be replaced (canonicalize_replace_cache),
then the shared_ptr to the client data is const.
* 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
Remove the implicit conversion from int64 to XRPAmount. The motivation for this
was noticing that many calls to `to_string` with an integer parameter type were
calling the wrong `to_string` function. Since the calls were not prefixed with
`std::`, and there is no ADL to call `std::to_string`, this was converting the
int to an `XRPAmount` and calling `to_string(XRPAmount)`.
Since `to_string(XRPAmount)` did the same thing as `to_string(int)` this error
went undetected.
Treat all `#` characters in config files as comments (and remove)
*unless* the `#` is immediately preceded by `\`. Write a warning
to log file when trailing comments are found/ignored in the config
to let operators know that the treatment of trailing `#` has changed.
Fixes#3121
The existing platform detection code was derived from the old Beast
library, which was, itself, derived from JUCE.
This commit removes that code and replaces it with the Boost.Predef
library which defines a consistent set of compiler, architecture,
operating system, library, and other version numbers.
For more on Boost.Predef, please see the Boost documentation. The
documentation for the current version as of this writing is at:
https://www.boost.org/doc/libs/1_71_0/doc/html/predef.html
