This algorithm is about an order of magnitude faster than the existing
algorithm (about 10x faster for encoding and about 15x faster for
decoding - including the double hash for the checksum). The algorithms
use gcc's int128 (fast MS version will have to wait, in the meantime MS
falls back to the slow code).
* It is now an invariant that all constructed Public Keys are valid,
non-empty and contain 33 bytes of data.
* Additionally, the memory footprint of the PublicKey class is reduced.
The size_ data member is declared as static.
* Distinguish and identify the PublisherList retrieved from the local
config file, versus the ones obtained from other validators.
* Fixes#2942
The compilation fails due to an issue in the initializer list
of an optional argument, which holds a vector of pairs.
The code compiles correctly on earlier gcc versions, but fails on gcc 13.
Implement native support for Price Oracles.
A Price Oracle is used to bring real-world data, such as market prices,
onto the blockchain, enabling dApps to access and utilize information
that resides outside the blockchain.
Add Price Oracle functionality:
- OracleSet: create or update the Oracle object
- OracleDelete: delete the Oracle object
To support this functionality add:
- New RPC method, `get_aggregate_price`, to calculate aggregate price for a token pair of the specified oracles
- `ltOracle` object
The `ltOracle` object maintains:
- Oracle Owner's account
- Oracle's metadata
- Up to ten token pairs with the scaled price
- The last update time the token pairs were updated
Add Oracle unit-tests
* Commit 01c37fe introduced a change to the STTx unit test where a local
"defaultRules" object was created with a temporary inline "presets"
value provided to the ctor. Rules::Impl stores a const ref to the
presets provided to the ctor. This particular call provided an inline
temp variable, which goes out of scope as soon as the object is
created. On Windows, attempting to use the presets (e.g. via the
enabled() function) causes an access violation, which crashes the test
run.
* An audit of the code indicates that all other instances of Rules use
the Application's config.features list, which will have a sufficient
lifetime.
Add `STObject` constructor to explicitly set the inner object template.
This allows certain AMM transactions to apply in the same ledger:
There is no issue if the trading fee is greater than or equal to 0.01%.
If the trading fee is less than 0.01%, then:
- After AMM create, AMM transactions must wait for one ledger to close
(3-5 seconds).
- After one ledger is validated, all AMM transactions succeed, as
appropriate, except for AMMVote.
- The first AMMVote which votes for a 0 trading fee in a ledger will
succeed. Subsequent AMMVote transactions which vote for a 0 trading
fee will wait for the next ledger (3-5 seconds). This behavior repeats
for each ledger.
This has no effect on the ultimate correctness of AMM. This amendment
will allow the transactions described above to succeed as expected, even
if the trading fee is 0 and the transactions are applied within one
ledger (block).
Prior to this commit, `port_grpc` could not be added to the [server]
stanza. Instead of validating gRPC IP/Port/Protocol information in
ServerHandler, validate grpc port info in GRPCServer constructor. This
should not break backwards compatibility.
gRPC-related config info must be in a section (stanza) called
[port_gprc].
* Close#4015 - That was an alternate solution. It was decided that with
relaxed validation, it is not necessary to rename port_grpc.
* Fix#4557
These headers are required in the xrpl Conan package in order for
xbridge witness server (xbwd) to build. This change to libxrpl may help
any dependents of libxrpl. This addition does not change any C++ code.
Without this amendment, an NFTokenAcceptOffer transaction can succeed
even when the NFToken recipient does not have sufficient reserves for
the new NFTokenPage. This allowed accounts to accept NFT sell offers
without having a sufficient reserve. (However, there was no issue in
brokered mode or when a buy offer is involved.)
Instead, the transaction should fail with `tecINSUFFICIENT_RESERVE` as
appropriate. The `fixNFTokenReserve` amendment adds checks in the
NFTokenAcceptOffer transactor to check if the OwnerCount changed. If it
did, then it checks the new reserve requirement.
Fix#4679
Use consistent platform-agnostic library names on all platforms.
Fix an issue that prevents dependents like validator-keys-tool from
linking to libxrpl on Windows.
It is bad practice to change the binary base name depending on the
platform. CMake already manipulates the base name into a final name that
fits the conventions of the platform. Linkers accept base names on the
command line and then look for conventional names on disk.
* Disable the Windows CI unit tests "allowed to fail" workaround which
was previously introduced in #4596.
* The runner hardware was upgraded, and the unit tests have been passing
since then.
Update to #4849, using a workaround for spurious codecov upload errors.
Spurious codecov upload errors are expected in public repos which rely
on PRs via forks. Retrying uploads is a decent and easy workaround.
Clients subscribed to `transactions` over WebSocket are being
disconnected because the traffic exceeds the default `send_queue_limit`
of 100.
This commit changes the default configuration, not the default in code.
Fix#4866
Resolves a warning that was emitted from the clang compiler. Switches
usage of the sprintf function to the recommended snprintf function.
Warning was observed in Apple clang version 15.0.0 (clang-1500.0.40.1).
Fix#4569
* Add logging for Application.cpp sweep()
* Improve lifetime management of ledger objects (`SLE`s)
* Only store SLE digest in CachedView; get SLEs from CachedSLEs
* Also force release of last ledger used for path finding if there are
no path finding requests to process
* Count more ST objects (derive from `CountedObject`)
* Track CachedView stats in CountedObjects
* Rename the CachedView counters
* Fix the scope of the digest lookup lock
Before this patch, if you asked "is it caching?" It was always caching.
Prevent WebSocket connections from trying to close twice.
The issue only occurs in debug builds (assertions are disabled in
release builds, including published packages), and when the WebSocket
connections are unprivileged. The assert (and WRN log) occurs when a
client drives up the resource balance enough to be forcibly disconnected
while there are still messages pending to be sent.
Thanks to @lathanbritz for discovering this issue in #4822.
This reverts commit 002893f280.
There were two files with conflicts in the automated revert:
- src/ripple/rpc/impl/RPCHelpers.h and
- src/test/rpc/JSONRPC_test.cpp
Those files were manually resolved.
Workaround for compilation errors with gcc-13 and other compilers
relying on `libstdc++` version 13. This is temporary until actual fix is
available for us to use: https://github.com/boostorg/beast/pull/2682
Some boost.beast files (which we do use) rely on an old gcc-12 behaviour
where `#include <cstdint>` was not needed even though types from this
header were used. This was broken by a change in libstdc++ version 13:
https://gcc.gnu.org/gcc-13/porting_to.html#header-dep-changes
The necessary fix was implemented in boost.beast, however it is not yet
available. Until it is available, we can use this workaround to enable
compilation of `rippled` with gcc-13, clang-16, etc.
