This change improves usability across network upgrades, by informing
users when their new transactions are being created with the consensus
branch ID from the previous epoch.
We only check failing signatures against the previous epoch to minimise
the extra computational load on nodes.
Refactor experimental feature handling
Adds new rpc call `getexperimentalfeatures` and also adds experimental features to `getblockchaininfo` output.
Closes#2671.
Bring the librustzcash crate into this repository
Rust dependencies are now canonically pinned within this repository by
`Cargo.lock`. We continue to use the depends system for vendoring the
dependencies, to ensure our Gitian builds continue to function (which have
no network access at build time, and fetch dependencies separately).
The `--enable-online-rust` configure flag replicates the behaviour of the
`LIBRUSTZCASH_OVERRIDE` environment variable (enabling the build system to
use https://crates.io instead of vendored dependencies).
This pulls in the exact version of `librustzcash` that we currently depend on
(corresponding to the `0.1.0` tag in https://github.com/zcash/librustzcash).
The changes to the crate since then will be pulled in as a separate PR.
Part of zcash/librustzcash#155.
Part of #4230.
Upgrade libsodium to 1.0.18
Includes patches that maintain consensus compatibility with libsodium 1.0.15 for Ed25519 pubkey and signature validation.
Replaces #4239. Closes#2872.
Remove time adjustment; instead warn if peer clocks are too different
The policy is: warn if we have seen at least 8 (TIMEDATA_WARNING_SAMPLES) peer times, in the version messages of the first 20 (TIMEDATA_MAX_SAMPLES) unique (by IP address) peers that connect, that are more than 10 minutes (TIMEDATA_WARNING_THRESHOLD seconds) but less than 10 days (TIMEDATA_IGNORE_THRESHOLD seconds) away from local time.
fixes#4338
This enables IDE integration to work (which requires the Cargo.toml to
be in the repo root).
"make clean" no longer runs "cargo clean", because IDE integrations hold
locks on files within the Rust build directory, and an error inside
"cargo clean" error would prevent "make clean" from completing (and
removing other files).
The --enable-online-rust configure flag replicates the behaviour of the
LIBRUSTZCASH_OVERRIDE environment variable (enabling the build system to
use crates.io instead of vendored dependencies).
The Cargo.lock is updated to account for the Zcash Rust crates no longer
being in the same workspace. Dependencies that were not transitive
dependencies of librustzcash are also removed, but no versions change.
