This is in preparation for removing the ability to generate
Sprout outputs from z_shieldcoinbase. Once that is complete,
we will no longer be able to use `z_shieldcoinbase` for test
setup for uses of Sprout funds; instead, the persisted blockchain
state created in this commit will be used for tests that require
the use of Sprout funds.
This brings the test framework into line with how Sprout funds
are now used on mainnet and testnet; existing Sprout funds may
be spent, and Sprout change may be created, but no funds may
be transfered into the Sprout pool, since the activation of
ZIP 211.
This change improves clock management for zcashd by ensuring
that all clock methods (obtaining seconds, milliseconds, and
microseconds since the epoch) agree under testing conditions
using `-mocktime`, and also adds a feature that allows tests
to specify an offset to the system clock; this is useful to
allow comprehensive testing of the "timejacking attack mitigation"
consensus rules.
Since the wallet ecosystem may not be fully updated to handle
v5 transaction parsing at the point of NU5 activation, some
nodes may prefer to construct V4 transactions when not including
Orchard transaction components.
This change adds a CLI flag that allows node users to specify
that preference.
z_mergetoaddress doesn't currently have any mechanism for specifying
the minconf value. We don't want to default back to a minconf of 1,
as before, because we'll be selecting anchors with at least 3
confirmations by default, so the simplest change here is to make
the minconf value default to the number of anchor confirmations, and
add a configurable minconf at some point in the future. It's likely
that `z_mergetoaddress` will end up being deprecated in any case,
so this works for now.
Also, ensure that anywhere that we're attempting to obtain the Orchard
anchor that we don't attempt to get an anchor from a height below NU5
activation.
This changes anchor selection and Orchard authentication path generation
to default to select anchors at a the depth specified by the
`-orchardanchorconfirmations` CLI argument, with a default anchor
selection depth of 10 blocks.
If the value of `minconf` used for a particular call to `z_sendmany` is
less than the the set number of Orchard anchor confirmations, `minconf`
will be used instead for the Orchard anchor confirmations depth,
so that the selected anchor will be certain to contain any notes
selected to be spent.
Fixes#5644
We've decided to remove the option to allow all deprecated features,
because this has the effect that, if a user enables this flag, they
won't get the warning (and hence may forget to take action) at the time
that a feature is moved from the default-allowed set to the
default-denied set.

This adds an `-allowdeprecated` CLI parameter whose value is a flag
indicating a deprecated feature that should be explicitly enabled.
Multiple instances of this argument may be provided. In the case that
this parameter is not provided, all currently deprecated RPC methods
that are not slated for removal in the next release remain available.
A user may disable all deprecated features entirely by providing the
string "none" as the argument to this parameter, or enable all
deprecated features, including those slated for removal, by providing
the string "all" as the argument to this parameter. In the case that
"all" or "none" is specified, multiple invocations of `-allowdeprecated`
are not permitted.
To explicitly enable only a specific set of deprecated features, use
`-allowdeprecated=<flag1> -allowdeprecated=<flagN> ...` when starting
zcashd. The following flags are recognized:
- "all" - enables all deprecated features.
- "none" - disables all deprecated features.
- "legacy_privacy" - enables the use of the deprecated "legacy" privacy
policy for z_sendmany. This causes the default behavior to conform to
the `FullPrivacy` directive in all cases instead of just for
transactions involving unified addresses.
- "getnewaddress" - enables the `getnewaddress` RPC method.
- "z_getnewaddress" - enables the `z_getnewaddress` RPC method.
- "zcrawreceive" - enables the `zcrawreceive` RPC method.
- "zcrawjoinsplit" - enables the `zcrawjoinsplit` RPC method.
- "zcrawkeygen" - enables the `zcrawkeygen` RPC method.
- "addrtype" - when this option is set, the deprecated `type` attribute
is returned in addition to `pool` or `address_type` (which contain the
same information) in the results of RPC methods that return address metadata.
That is, without having to launch with test_runner.py. There are
several places where the BITCOIND environment variable determines the
executable, but the default is "bitcoind"; change the default to
"src/zcashd". This does require running the test from the top-level
directory.
Also change the environment variable from BITCOIND to ZCASHD. This could
conceivable break someone, but it just makes too much sense not to do.
the warning before test 4r is generated by the check_z_mergetoaddress
at line 459, which moves all the sapling funds into taddr_2 and thus
expects (sapling_balance - DEFAULT_FEE) to show up into taddr_2.
However, the check_z_mergetoaddress_parallel at line 418 had already
funded taddr_2 (with the sum of taddr_1 and taddr_3), and so we need to
add that to the amount of money that check_z_mergetoaddress at line 459
expects to find.
For consistency, we serialize the `finalState` field in the
same (sparse) encoding as Sapling and Sprout use. In the future
we may want to update this to the dense encoding that
incrementalmerkletree::bridgetree::Frontier uses, but that's not
necessary for the moment.
This adds tests to wallet_z_sendmany that demonstrates conditions
where pool-crossing transfers were not being caught by the privacy
policy checks, which were validating only against the transfer
request rather than the actual transfer selected. This missed
cases where sending funds between unified addresses would reveal
amounts via the turnstile.
Making all privacy policy checks after note selection guards against
this error.
If a new Orchard wallet is created after the first Orchard spend
post NU5 activation, it causes an assertion failure because the root
of the wallet's empty note commitment tree does not match the global
note commitment tree root.
The test fails during the final `z_sendmany`, because it is selecting a
note that was detected before restarting the node. Because we force the
wallet to call `SetBestChain` on every block, the wallet doesn't need to
rescan on restart, and thus doesn't repopulate the `position` field of
the in-memory note.
This issue went unnoticed in existing tests that exercise node restarts,
because the RPC tests are fast enough that they never pass the 10-minute
timeout for writing the wallet state. This commit adds a regtest-only
config option that disables the lazy writing.
Make consistent use of "pool", "address type" and "receiver type",
in RPC documentaion, and deprecate bare uses of "type" in RPC APIs.
