486c1eea86 refactoring: remove unused chainActive (James O'Beirne)
631940aab2 scripted-diff: replace chainActive -> ::ChainActive() (James O'Beirne)
a3a609079c refactoring: introduce unused ChainActive() (James O'Beirne)
1b6e6fcfd2 rename: CChainState.chainActive -> m_chain (James O'Beirne)
Pull request description:
This is part of the assumeutxo project:
Parent PR: #15606
Issue: #15605
Specification: https://github.com/jamesob/assumeutxo-docs/tree/2019-04-proposal/proposal
---
This change refactors the `chainActive` reference into a `::ChainActive()` call. It also distinguishes `CChainState`'s `CChain` data member as `m_chain` instead of the current `chainActive`, which makes it easily confused with the global data.
The active chain must be obtained via function because its reference will be swapped at some point during runtime after loading a UTXO snapshot.
This change, though lengthy, should be pretty easy to review since most of it is contained within a scripted-diff. Once merged, the parent PR should be easier to review.

77851ab682bf94f78874a245919bcc4b79dc054e GUI: Refactor actual QR code rendering into new QRImageWidget::setQR (Luke Dashjr)
Pull request description:
For at least QR-code based pairing of mobile wallets with nodes, it will be desirable to render QR codes even without wallet support.
Therefore, this prepares by moving the QRImageWidget out of a wallet-specific file into its own `qrencoder` file-pair.

Pull request description:
This is a rebase of #11639 with some fixes for the last few comments which were not yet addressed.
The original PR text, with some strikethroughs of text that is no longer correct:
> This cleans up an old main-carryover - it made sense that main could decide what DoS scores to assign things because the DoS scores were handled in a different part of main, but now validation is telling net_processing what DoS scores to assign to different things, which is utter nonsense. Instead, we replace CValidationState's nDoS and CorruptionPossible with a general ValidationInvalidReason, which net_processing can handle as it sees fit. I keep the behavior changes here to a minimum, but in the future we can utilize these changes for other smarter behavior, such as disconnecting/preferring to rotate outbound peers based on them providing things which are invalid due to SOFT_FORK because we shouldn't ban for such cases.
>
> This is somewhat complementary with, though obviously conflicts heavily with #11523, which added enums in place of DoS scores, as well as a few other cleanups (which are still relevant).
>
> Compared with previous bans, the following changes are made:
>
> Txn with empty vin/vout or null prevouts move from 10 DoS
> points to 100.
> Loose transactions with a dependency loop now result in a ban
> instead of 10 DoS points.
> ~~BIP68-violation no longer results in a ban as it is SOFT_FORK.~~
> ~~Non-SegWit SigOp violation no longer results in a ban as it
> considers P2SH sigops and is thus SOFT_FORK.~~
> ~~Any script violation in a block no longer results in a ban as
> it may be the result of a SOFT_FORK. This should likely be
> fixed in the future by differentiating between them.~~
> Proof of work failure moves from 50 DoS points to a ban.
> Blocks with timestamps under MTP now result in a ban, blocks
> too far in the future continue to not result in a ban.
> Inclusion of non-final transactions in a block now results in a
> ban instead of 10 DoS points.
Note: The change to ban all peers for consensus violations is actually NOT the change I'd like to make -- I'd prefer to only ban outbound peers in those situations. The current behavior is a bit of a mess, however, and so in the interests of advancing this PR I tried to keep the changes to a minimum. I plan to revisit the behavior in a followup PR.
EDIT: One reviewer suggested I add some additional context for this PR:
> The goal of this work was to make net_processing aware of the actual reasons for validation failures, rather than just deal with opaque numbers instructing it to do something.
>
> In the future, I'd like to make it so that we use more context to decide how to punish a peer. One example is to differentiate inbound and outbound peer misbehaviors. Another potential example is if we'd treat RECENT_CONSENSUS_CHANGE failures differently (ie after the next consensus change is implemented), and perhaps again we'd want to treat some peers differently than others.

Though at the moment ChainActive() simply references `g_chainstate.m_chain`,
doing this change now clears the way for multiple chainstate usage and allows
us to script the diff.
-BEGIN VERIFY SCRIPT-
git grep -l "chainActive" | grep -E '(h|cpp)$' | xargs sed -i '/chainActive =/b; /extern CChain& chainActive/b; s/\(::\)\{0,1\}chainActive/::ChainActive()/g'
-END VERIFY SCRIPT-
|
|
in preparation for the following scripted-diff commit.
|
|
This can't be a scripted-diff due to the confusion of the global
chainActive and the CChainState member of the same name.
This specific rename makes the following chainActive -> ::ChainActive() diff
scriptable.

This is a first step towards cleaning up our DoS interface - make
validation return *why* something is invalid, and let net_processing
figure out what that implies in terms of banning/disconnection/etc.
Behavior change: peers will now be banned for providing blocks
with premature coinbase spends.
Co-authored-by: Anthony Towns <aj@erisian.com.au>
Suhas Daftuar <sdaftuar@gmail.com>

|
|
This eliminates a discrepancy between block validation with multiple
script check threads, versus a single script check thread.
|
|
Compared with previous bans, the following changes are made:
* Txn with empty vin/vout or null prevouts move from 10 DoS
points to 100.
* Loose transactions with a dependency loop now result in a ban
instead of 10 DoS points.
* Many pre-segwit soft-fork errors now result in a ban.
Note: Transactions that violate soft-fork script flags since P2SH do not generally
result in a ban. Also, banning behavior for invalid blocks is dependent on
whether the node is validating with multiple script check threads, due to a long-
standing bug. That inconsistency is still present after this commit.
* Proof of work failure moves from 50 DoS points to a ban.
* Blocks with timestamps under MTP now result in a ban, blocks
too far in the future continue to *not* result in a ban.
* Inclusion of non-final transactions in a block now results in a
ban instead of 10 DoS points.

This comment was confusing and incorrect when first added ("invalid rather than
merely non-standard" has the opposite meaning of what is actually the case),
and was also not updated after segwit with the correct variable names.
Delete it since the code reads just fine on its own.
