The only upstream change relative to the previous commit is that the
various Zcash-specific dependencies have been pulled into a cargo
workspace. The dependecies in the workspace use the same commits as the
crates we had previously vendored.
The patches are necessary to handle the fact that cargo requires that
dev dependencies are available even if not used, and we would otherwise
need to vendor all the underlying crates.
Fix potentially misleading test failures
This is in response to https://github.com/zcash/zcash/pull/3590#discussion_r224677644
Currently statements such as:
```assert_equal("Embarassment", "Embarrassment", "Misspelling detected")```
Will produce essentially the following error:
```
Assertion failed: Misspelling detected; expected: <Embarassment> but was: <Embarrassment>
File "/home/eirik/Development/zcash/qa/rpc-tests/test_framework/test_framework.py", line 121, in main
self.run_test()
File "/home/eirik/Development/zcash/qa/rpc-tests/test_spelling.py", line 13, in run_test
```
Which is misleading because the item on the left is not what is actually expected.
This PR changes the assertion failure to be displayed as:
```
Assertion failed: (left == right); Misspelling detected
left: <Embarassment>
right: <Embarrassment>
File "/home/eirik/Development/zcash/qa/rpc-tests/test_framework/test_framework.py", line 121, in main
self.run_test()
File "/home/eirik/Development/zcash/qa/rpc-tests/test_spelling.py", line 13, in run_test
```
Closes#3467. Add benchmarks for Sapling spends and outputs.
Four new benchmarks are added to RPC zcbenchmark:
- createsaplingspend
- createsaplingoutput
- verifysaplingspend
- verifysaplingoutput
Remove GetUnspentFilteredNotes
Closes#3580
This PR generalized `GetFilteredNotes`, expanding its functionality to also do what we do in `GetUnspentFilteredNotes`. This enables us to remove the latter.
Make it clear that CWallet::GenerateNewZKey is Sprout specific
Closes https://github.com/zcash/zcash/issues/3577
When adding sapling support we had considered making the method `GenerateNewZKey` generic, but it ended up making more sense to add a second method `GenerateNewSaplingZKey` for sapling support.
This PR changes the name of `GenerateNewZKey` to `GenerateNewSproutZKey` and changes the return type from `libzcash::PaymentAddress` to `libzcash::SproutPaymentAddress` to make it more clear that this is what the method does.
Clarify in sendmany/z_sendmany rpc docs that amounts are not FP
Fixes#3539
I clarified in the docs that only 8 digits of precision are allowed. For example, if you try 9 digits you will get:
```
zcash-cli z_sendmany $TADDR "[{\"address\":\"$ZADDR\",\"amount\":0.123456789}]"
error code: -3
error message:
Invalid amount
```
