We added support for the NU5 consensus rules in v4.5.0, which alters the
block header to contain a `hashBlockCommitments` value instead of the
chain history root. However, the output of `getblocktemplate` wasn't
returning this value; once NU5 activated, the `blockcommitmentshash`
field was being set to "null" (all-zeroes).
In v4.6.0 we added full NU5 support to `getblocktemplate`, by adding a
`defaultroots` field that gave default values for `hashBlockCommitments`
and the components required to derive it. However, in doing so we
introduced a regression in the (now-deprecated) legacy fields, where
prior to NU5 activation they contained nonsense.
This commit fixes the output of `getblocktemplate` to have the intended
semantics for all fields:
- The `blockcommitmentshash` and `authdataroot` fields in `defaultroots`
are now omitted from block templates for heights before NU5 activation.
- The legacy fields now always contain the default value to be placed
into the block header (regaining their previous semantics).

This test currently fails with submitblock returning the error
"bad-heartwood-root-in-block".
Added authdigest to GBT coinbasetxn field because we can't obtain this

This will ensure that miners can use the values returned by
getblocktemplate (in particular, the block commitment hash)
to submit a valid block using the submitblock RPC.
zcash/zcash:
The `getmininginfo` RPC now omits `currentblockize` and `currentblocktx`
when a block was never assembled via RPC on this node during its current
process instantiation. The relevant RPCs are `generate` (regtest only) and
`getblocktemplate`. Blocks are also assembled when running the internal
miner (`zcashd -gen=1`), after the node mines its first block.
(cherry picked from commit bitcoin/bitcoin@fa178a6385)
This test-only change allows python (rpc) tests to specify, for example,
that NU5 should be activated at height X, without having to specify all
the previous network upgrades. Previous upgrades can (and must) still be
specified if they activate at different block heights (than, in this
example, NU5). This makes tests easier to write (and read), especially
as the number of network upgrades increases over time.
Note that this change only affects zcashd behavior in regtest mode. For
the other network modes (testnet and mainnet), the activation heights
are hard-coded in chainparams.cpp.
Adds HD seed derivation from ZIP-339 mnemonic phrases.
This replaces random generation of transparent spending keys with BIP-44-compatible derivation from a mnemonic seed phrase, and replaces the random HD seed previously used for Sapling HD key derivation
with the same mnemonic seed. After this change, all new transparent and Sapling addresses
will be derived from a new randomly generated mnemonic seed, which is produced in such a way that
it is guaranteed to produce valid unified spending keys at account 0 for all address types.
Closes#5176.
Closes#2673.
After 4.5.2, all wallets will be populated with an emergency
recovery phrase, and all future addresses will be derived from
the associated seed. To prevent potential loss of funds, we
require that the user explicitly invoke the `walletconfirmbackup`
RPC method to verify that they have backed up this seed.
We aren't going to move to Clang 13 in a hotfix release. The other
dependencies passed their postponement re-evaluation date, but also
won't be updated just yet.
The "IsFromMe" logic was implemented in several places in the Bitcoin
Core wallet. We had correctly updated CWallet::IsFromMe(CTransaction)
(which was used in most places in the wallet) to check for shielded
notes being spent, but did not notice that CWalletTx::IsFromMe also
needed this check.
This bug has existed since before Zcash launched. It went unnoticed
because CWalletTx::IsFromMe was previously only called from code
used to either create purely-transparent transactions, or provide
informational output on non-critical RPC methods.

- The patches `iostreams-106.patch` and `signals2-noise.patch` were
incorporated into Boost 1.75.
- The allocator access deprecation issue was fixed in Boost 1.76.
Closeszcash/zcash#4945.
This adds the double-hash message variant. The extra hash field is set
to null for block message types, and to all-ones for MSG_TX (to match
the legacy authHash value used for pre-v5 transactions in the Merkle
tree).
I tested the NU5 components of this PR by locally setting the protocol
version to 170014. I forgot to check that without that override, the
test would skip the NU5 checks. The reason it defaulted to NU5 is that
the test was reading the client version 4040150, which is indeed not
less than the NU5 protocol version ^_^;;
Extend P2P test framework to make it possible to expect reject
codes for transactions and blocks.

ZIP 239 preparations 2
Cherry-picked from the following upstream PRs:
- bitcoin/bitcoin#6722
- Only the ancillary commits, not the mempool limiting commits (we have our own).
- bitcoin/bitcoin#6898
- Only the first three commits (we'll cherry-pick the main content later).
- bitcoin/bitcoin#7840
Also remove the RPC deprecation tests for accounts, and make one small
change to another wallet test that relies on account behaviour.
(cherry picked from commit f0dc850bf698f7377797d7d68365d4fc79b0221c)
Previously Bitcoin would send 1/4 of transactions out to all peers
instantly. This causes high overhead because it makes >80% of
INVs size 1. Doing so harms privacy, because it limits the
amount of source obscurity a transaction can receive.
These randomized broadcasts also disobeyed transaction dependencies
and required use of the orphan pool. Because the orphan pool is
so small this leads to poor propagation for dependent transactions.
When the bypass wasn't in effect, transactions were sent in the
order they were received. This avoided creating orphans but
undermines privacy fairly significantly.
This commit:
Eliminates the bypass. The bypass is replaced by halving the
average delay for outbound peers.
Sorts candidate transactions for INV by their topological
depth then by their feerate (then hash); removing the
information leakage and providing priority service to
higher fee transactions.
Limits the amount of transactions sent in a single INV to
7tx/sec (and twice that for outbound); this limits the
harm of low fee transaction floods, gives faster relay
service to higher fee transactions. The 7 sounds lower
than it really is because received advertisements need
not be sent, and because the aggregate rate is multipled
by the number of peers.
(cherry picked from commit f2d3ba73860e875972738d1da1507124d0971ae5)
Zcash: Candidate transactions for INV are not sorted by their
topological depth because we haven't backported bitcoin/bitcoin#6654.
ZIP 239 preparations 1
This is the first of several backports to prepare for ZIP 239. The primary
change is altering `mapRelay` to store `CTransaction`s, which we need
because ZIP 239 requires changing `Inv` messages based on transaction
versions. The other changes are mainly for conflict removal but are also
independently useful.
Backports the following upstream PRs:
- bitcoin/bitcoin#6889
- bitcoin/bitcoin#7125
- bitcoin/bitcoin#7862
- bitcoin/bitcoin#7877
The recent changes to mempool inv logic mean that nodes are much less
likely to immediately return an `inv` message in response to a `mempool`
message. The `p2p_txexpiringsoon` RPC test was relying on the prior
behaviour.
`TestNode.sync_with_ping` now takes an optional `waiting_for` closure
that allows the caller to require that a specific message kind is
received prior to the timeout.
This is the second release in a row where LLVM has cut a X.0.1 for
everything except Darwin, so I've adjusted its URLs and paths on the
assumption this will continue.
Bitcoin Core doesn't actually use tags for managing versions of their
forked dependencies, so we should separately rework this logic for all
of the subtree-managed dependencies. But this at least prevents false
positives.
Split wallet.py
Split some of the tests from `wallet.py` into its own files to make it easier to debug.
Some of the tests moved where depending(specially in balance amounts) on previous code. As standalone, some of the hardcoded balances needed some changes. No further modifications to tests are done in this PR.
We can split more but i think is a good start.
If this is merged it will close https://github.com/zcash/zcash/issues/4917

Reduce default fee to 1000 zatoshis
Per ZIP 313. This also ensures that transactions that pay the default fee will always be relayed, and not rate-limited.
This removes the paches iostreams-106.patch and signals2-noise.patch
which have been incorporated into boost 1.75. Also, this further
postpones updates to native_clank, libcxx and native_ccache.
A few miscellaneous improvements to rpc-tests.py command line arguments:
- make all arguments start with double dash for consistency
- improve help text and output
- add nozmq argument to explicitly exclude the ZMQ tests
- change 'parallel' to 'jobs'
- Link pull-tester/rpc-tests.py to the build dir
- Add the build-dir's config to the python path so that tests can find it
- The tests themselves are in srcdir
- Clean up __pycache__ in 'make clean'
Previously these functions would infinitely loop if sync failed;
now they have a default timeout of 60 seconds, after which an
AssertionError is raised.
sync_blocks() has also been improved and now compares the tip
hash of each node, rather than just using block count.
Zcash: Kept block count check for a couple of tests where we use it.
