e6fe1c37d0a2f8037996dd80619d6c23ec028729 rpc: Improve avoidpartialspends and avoid_reuse documentation (Fabian Jahr)
8f073076b102b77897e5a025ae555baae3d1f671 wallet: Increase OUTPUT_GROUP_MAX_ENTRIES to 100 (Fabian Jahr)
Pull request description:
Follow-up to #17824.
This increases OUTPUT_GROUP_MAX_ENTRIES to 100 which means that OutputGroups will now be up to 100 outputs large, up from previously 10. The main motivation for this change is that during the PR review club on #17824 [several participants signaled](https://bitcoincore.reviews/17824.html#l-339) that 100 might be a better value here.
I think fees should be manageable for users but more importantly, users should know what they can expect when using the wallet with this configuration, so I also tried to clarify the documentation on `-avoidpartialspends` and `avoid_reuse` a bit. If there are other additional ways how or docs where users can be made aware of the potential consequences of using these parameters, please let me know. Another small upside is that [there seem to be a high number of batching transactions with 100 and 200 inputs](https://miro.medium.com/max/3628/1*sZ5eaBSbsJsHx-J9iztq2g.png)([source](https://medium.com/@hasufly/an-analysis-of-batching-in-bitcoin-9bdf81a394e0)) giving these transactions a bit of a larger anonymity set, although that is probably a very weak argument.

c7437185589926ec8def2af6bede6a407b3d2e4a test: add further BIP37 size limit checks to p2p_filter.py (Sebastian Falbesoner)
Pull request description:
This is a follow-up PR to #18628. In addition to the hash-functions limit test introduced with commit fa4c29bc1d, it adds checks for the following size limits as defined in [BIP37](https://github.com/bitcoin/bips/blob/master/bip-0037.mediawiki):
ad message type `filterload`:
> The filter itself is simply a bit field of arbitrary byte-aligned size. The maximum size is **36,000 bytes**.
ad message type `filteradd`:
> The data field must be smaller than or equal to **520 bytes** in size (the maximum size of any potentially matched object).
Also introduces new constants for the limits (or reuses the max script size constant in case for the `filteradd` limit).
Also fixes#18711 by changing the misbehaviour check on "filteradd without filterset" (introduced with #18544) below to also use the more commonly used `assert_debug_log` method.

5eae034996b340c19cebab9efb6c89d20fe051ef net: limit BIP37 filter lifespan (active between 'filterload' and 'filterclear') (Sebastian Falbesoner)
Pull request description:
This PR fixes https://github.com/bitcoin/bitcoin/issues/18483. On the master branch, there is currently _always_ a BIP37 filter set for every peer: if not a specific filter is set through a `filterload` message, a default match-everything filter is instanciated and pointed to via the `CBloomFilter` default constructor; that happens both initially, when the containing structure `TxRelay` is constructed:
c0b389b335/src/net.h (L812)
and after a loaded filter is removed again through a `filterclear` message:
c0b389b335/src/net_processing.cpp (L3201)
The behaviour was introduced by commit 37c6389c5a (an intentional covert fix for [CVE-2013-5700](https://github.com/bitcoin/bitcoin/pull/18515), according to gmaxwell).
This default match-everything filter leads to some unintended side-effects:
1. `getdata` request for filtered blocks (i.e. type `MSG_FILTERED_BLOCK`) are always responded to with `merkleblock`s, even if no filter was set by the peer, see issue #18483 (strictly speaking, this is a violation of BIP37) c0b389b335/src/net_processing.cpp (L1504-L1507)
2. if a peer sends a `filteradd` message without having loaded a filter via `filterload` before, the intended increasing of the banscore never happens (triggered if `bad` is set to true, a few lines below) c0b389b335/src/net_processing.cpp (L3182-L3186)
This PR basically activates the `else`-branch code paths for all checks of `pfilter` again (on the master branch, they are dead code) by limiting the pointer's lifespan: instead of always having a filter set, the `pfilter` is only pointing to a `CBloomFilter`-instance after receiving a `filterload` message and the instance is destroyed again (and the pointer nullified) after receiving a `filterclear` message.
Here is a before/after comparison in behaviour:
| code part / scenario | master branch | PR branch |
| --------------------------------------------- | ---------------------------------- | ---------------------------------------------------- |
| `getdata` processing for `MSG_FILTERED_BLOCK` | always responds with `merkleblock` | only responds if filter was set via `filterload` |
| `filteradd` processing, no filter was loaded | nothing | peer's banscore increases by 100 (i.e. disconnect) |
On the other code parts where `pfilter` is checked there is no change in the logic behaviour (except that `CBloomFilter::IsRelevantAndUpdate()` is unnecessarily called and immediately returned in the master branch).
Note that the default constructor of `CBloomFilter` is only used for deserializing the received `filterload` message and nowhere else. The PR also contains a functional test checking that sending `getdata` for filtered blocks is ignored by the node if no bloom filter is set.

we can not re-sign expired transaction of asset-unlock. CRangesList is protected from this situation
## Issue being fixed or feature implemented
## What was done?
Renaming of all classes/variables/functions/rpcs from `hpmn` to `evo`.
## How Has This Been Tested?
All unit and func tests are passing.
Sync of Testnet.
## Breaking Changes
All protx RPCs ending with `_hpmn` were converted to `_evo`.
`_hpmn` RPCs are now deprecated.
Although, they can still be enabled by adding `-deprecatedrpc=hpmn`.

92e28fa8b2590cce0e8f0adadae80e46cb63a9ef test: remove unused constants in functional tests (Sebastian Falbesoner)
Pull request description:
This mini-PR gets rid of constants in functional tests that are not used anymore. Found by [vulture ](https://pypi.org/project/vulture/)via the following script that has been lying around here locally for quite some time (I think it was once proposed by practicalswift, but I don't remember the concrete topic/PR):
```
#!/bin/sh
for F in $(git ls-files -- "*.py"); do vulture "$F" | grep "unused variable"; done
```

## Issue being fixed or feature implemented
Current implementation of MnEhfTx is not matched with DIP-0023, this PR
fixes it. It is a prior work for
https://github.com/dashpay/dash/pull/5469
## What was done?
- requestID is fixed from `clsig{quorumHeight}` to `mnhf{versionBit}` +
fixes for signature validation properly
- v20 is minimal height to accept MnEHF special transactions
- versionBit is not BLS version - removed unrelated wrong code and
validations
- TxMempool will accept MnEHF transaction even if inputs/outputs are
zeroes and no fee
- implemented python's serialization/deserialization of MnEHF
transactions for future using in functional tests
## How Has This Been Tested?
Run functional/unit tests. Beside that there's new functional test in
https://github.com/dashpay/dash/pull/5469 that actually test format of
transaction and signature validation - to be merged later.
## Breaking Changes
Payload of MnEhf tx is changed, related consensus rules are changed.

## Issue being fixed or feature implemented
The logic for additional indexes is incomplete, handling of P2PK on
block disconnect is broken (luckily no one is using P2PK and reorgs are
rare) and there are a few other small issues that would be nice to have
fixed.
## What was done?
Pls see individual commits
## How Has This Been Tested?
Run `feature_dbcrash.py`, it should succeed (NOTE: it takes ~30 minutes
to complete, that's normal).
Run `feature_addressindex.py`, `feature_timestampindex.py` and
`feature_spentindex.py` (and other tests) should still succeed too.

## Issue being fixed or feature implemented
This is an implementation of DIP0027 "Credit Asset Locks".
It's a mechanism to fluidly exchange between Dash and credits.
## What was done?
This pull request includes:
- Asset Lock transaction
- Asset Unlock transaction (withdrawal)
- Credit Pool in coinbase
- Unit tests for Asset Lock/Unlock tx
- New functional test `feature_asset_locks.py`
RPC: currently locked amount (credit pool) is available through rpc call
`getblock`.
## How Has This Been Tested?
There added new unit tests for basic checks of transaction validity
(asset lock/unlock).
Also added new functional test "feature_asset_locks.py" that cover
typical cases, but not all corner cases yet.
## Breaking Changes
This feature should be activated as hard-fork because:
- It adds 2 new special transaction and one of them [asset unlock tx]
requires update consensus rulels
- It adds new data in coinbase tx (credit pool)

## Issue being fixed or feature implemented
V19 is active on mainnet/testnet now, no need to check activation bits
anymore. This PR also bumps `MinBIP9WarningHeight` to
post-v19-activation height which should stop `unknown new rules
activated (versionbit 8)` warning from appearing.
## What was done?
Bury v19, bump `MinBIP9WarningHeight`
## How Has This Been Tested?
Run tests, reindex on mainnet/testnet.

5aadd4be1883386a04bef6a04e9a1142601ef7a7 Convert amounts from float to decimal (Prayank)
Pull request description:
> decimal is preferred in accounting applications
https://docs.python.org/3.8/library/decimal.html
Decimal type saves an exact value so better than using float.
~~3 variables declared with type as 'Decimal' in [test/functional/mempool_accept.py](https://github.com/bitcoin/bitcoin/blob/master/test/functional/mempool_accept.py): fee, fee_expected, output_amount~~
~~Not required to convert to string anymore for using the above variables as decimal~~
+ fee, fee_expected, output_amount
~~+ 8 decimal places~~
+ Using value of coin['amount'] as decimal and removed 'int'
+ Removed unnecessary parentheses
+ Remove str() and use quotes
Fixes https://github.com/bitcoin/bitcoin/issues/20011

1abbdac6777bc5396d17a6772c8176a354730997 wallet: Prefer full destination groups in coin selection (Fabian Jahr)
Pull request description:
Fixes#17603 (together with #17843)
In the case of destination groups of >10 outputs existing in a wallet with `avoid_reuse` enabled, the grouping algorithm is adding left-over outputs as an "incomplete" group to the list of groups even when a full group has already been added. This leads to the strange behavior that if there are >10 outputs for a destination the transaction spending from that will effectively use `len(outputs) % 10` as inputs for that transaction.
From the original PR and the code comment I understand the correct behavior should be the usage of 10 outputs. I opted for minimal changes in the current code although there maybe optimizations possible for cases with >20 outputs on a destination this sounds like too much of an edge case right now.
