This PR updates protobuf and grpc to their latest versions. The latest protobuf version no longer requires patches, so we can use it directly from the official Conan Center Index, while the latest grpc still needed a patch, which was added to our own Conan Center Index fork in XRPLF/conan-center-index#8.
This change substitutes the secp256k1 source code copy by the Conan recipe added in XRPLF/conan-center-index#24, which updates the version of the library to 0.7.0.
- Spec: XLS-66
- Introduces amendment "LendingProtocol", but leaves it UNSUPPORTED to
allow for standalone testing, future development work, and potential
bug fixes.
- AccountInfo RPC will indicate the type of pseudo-account when
appropriate.
- Refactors and improves several existing classes and functional areas,
including Number, STAmount, STObject, json_value, Asset, directory
handling, View helper functions, and unit test helpers.
This change moves the lockfile instructions into a script, and instead of removing packages it sets the Conan home directory to a temporary directory.
There are several advantages, such as:
* Not affecting the user's Conan home directory, so there is no need to remove packages.
* Only the script needs to be run, rather than several commands.
This change updates the instructions for how to generate a Conan lockfile that is compatible with Linux, macOS, and Windows.
Whenever Conan dependencies change, the Conan lock file needs to be regenerated. However, different OSes have slightly different requirements, and thus require slightly different dependencies. Luckily a single `conan.lock` file can be used, as long as the union of dependencies is included.
The current instructions in the `BUILD.md` file are insufficient to regenerate the lock file such that it is compatible with all OSes, which this change addresses. The three profiles contain the bare minimum needed to generate the lockfile; it does not particularly matter whether the build type is Debug or Release, for instance.
This change triggers the Clio pipeline on PRs that target any of the `release*` branches (in addition to the `master` branch), as opposed to only the `release` branch.
If the config disables SQL db usage, such as a validator:
```
[ledger_tx_tables]
use_tx_tables = 0
```
then the pointer to DB engine is null, but it was still resolved during startup. Although it didn't crash in Release mode, possibly due to the compiler optimizing it away, it did crash in Debug mode. This change explicitly checks for the validity of the pointer and generates a runtime error if not set.
The `ledger_entry` and `deposit_preauth` requests require an array of credentials. However, the array size is not checked before is gets processing. This fix adds checks and return errors in case array size is too big.
This PR splits `RPCHelpers.h` into two files, by moving out all the ledger-fetching-related functions into a separate file, `RPCLedgerHelpers.h`. It also moves `getAccountObjects` to `AccountObjects.h`, since it is only used in that one place.
Technically b0 is not a release, so no "release" prefix here. It marks the point at which we moved the preceding release (3.0.0 in this case) from Beta to Release Candidate.
