24bf17602c gui refactor: Inline SplashScreen::ConnectWallet (Russell Yanofsky)
e4f4350471 refactor: Move wallet methods out of chain.h and node.h (Russell Yanofsky)
b266b3e0bf refactor: Create interfaces earlier during initialization (Russell Yanofsky)
Pull request description:
Add WalletClient interface so node interface is cleaner and don't need wallet-specific methods.
The new NodeContext::wallet_client pointer will also be needed to eliminate global wallet variables like ::vpwallets in #19101, because createWallet(), loadWallet(), getWallets(), etc methods called by the GUI need a way to get a reference to the list of open wallets if it is no longer a global variable.

Add AppInitInterfaces function so wallet chain and chain client interfaces are
created earlier during initialization. This is needed in the next commit to
allow the gui splash screen to be able to register for wallet events through a
dedicated WalletClient interface instead managing wallets indirectly through
the Node interface. This only works if the wallet client interface is created
before the splash screen needs to use it.

fa33bc2dab init: Capture copy of blocknotify setting for BlockNotifyCallback (MarcoFalke)
fa40017706 init: Pass reference to ArgsManager around instead of relying on global (MarcoFalke)
Pull request description:
The gArgs global has several issues:
* gArgs is used by each process (bitcoind, bitcoin-qt, bitcoin-wallet, bitcoin-cli, bitcoin-tx, ...), but it is hard to determine which arguments are actually used by each process. For example arguments that have never been registered, but are still used, will always return the fallback value.
* Tests may run several sub-tests, which need different settings. So globals will have to be overwritten, but that is fragile on its own: e.g. https://github.com/bitcoin/bitcoin/pull/19704#issuecomment-678259092 or #19511
The goal is to remove gArgs, but as a first step in that direction this pull will change gArgs in init to use a passed-in reference instead.

Hold a reference to connman rather than a pointer because:
- PeerLogicValidation can't run without a connman
- The pointer never gets reseated
The alternative is to always assert that the pointer is non-null before
dereferencing.
Change the name from connman to m_connman at the same time to conform
with current style guidelines.
For a couple of years, Tor documentation has made
the term hidden service obsolete, in favor of onion
service.

Pull request description:
This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11):
Parent PR: #15606
Issue: #15605
Specification: https://github.com/jamesob/assumeutxo-docs/tree/master/proposal
---
In the assumeutxo implementation draft (#15056), once a UTXO snapshot is loaded, a new chainstate object is created after initialization. This means that we have to reclaim some of the cache that we've allocated to the original chainstate (per `dbcache=`) to repurpose for the snapshot chainstate.
Furthermore, it makes sense to have different cache allocations depending on which chainstate is more active. While the snapshot chainstate is working to get to the network tip (and the background validation chainstate is idle), it makes sense that the snapshot chainstate should have the majority of cache allocation. And contrariwise once the snapshot has reached network tip, most of the cache should be given to the background validation chainstate.
This set of changes (detailed in the commit messages) allows us to dynamically resize the various coins caches. None of the functionality introduced here is used at the moment, but will be in the next AU PR (which introduces `ActivateSnapshot`).
`ChainstateManager::MaybeRebalanceCaches()` defines the (somewhat normative) cache allocations between the snapshot and background validation chainstates. I'd be interested in feedback if anyone has thoughts on the proportions I've set there.

ec4c6a17e8 scripted-diff: replace MAX_BLOCKS_ONLY_CONNECTIONS with MAX_BLOCK_RELAY_ONLY_CONNECTIONS (glowang)
Pull request description:
We have two different concepts that have similar names: `-blocksonly` and `block-relay-only`, and the similarity of names could lead to confusion. `-blocksonly` disables all local receiving & relaying of transactions (with a few exceptions), while `block-relay-only`means that bitcoind will make 2 additional outbound connections that are only used for block relay.
In net.h and init.cpp, `MAX_BLOCKS_ONLY_CONNECTIONS` is used to represent the maximum number of `block-relay-only` outbound peers, which is 2. But this name sounds ambiguous, and I proposed a better name, `MAX_BLOCK_RELAY_ONLY_CONNECTION`.

This patch improves performance and resource usage around IP addresses that are banned for misbehavior. They're already not actually banned since #14929, as connections from them are still allowed, but they are preferred for eviction if the inbound connection slots are full.

fa0dfdf447 refactor: Remove confusing BlockIndex global (MarcoFalke)
Pull request description:
The global `::BlockIndex()` is problematic for several reasons:
* It returns a mutable reference to the block tree, without the appropriate lock annotation (`m_block_index` is guarded by `cs_main`). The current code is fine, but in the future this might lead to accidental races and data corruption.
* The rpc server shouldn't rely on node globals, but rather a context that is passed in to the RPC method.
* Tests might want to spin up their own block tree, and thus should also not rely on a single global.

defined. This simplifies call sites: no more `InitError(Untranslated(...))`.
- Make all functions in `util/error.h` consistently return a

let's roll with it.
This has no functional changes: no messages are changed, no new

Building with -Wunreachable-code-loop-increment causes a warning
due to always returning on the first iteration of the loop that
outputs errors on invalid args.
Collect all errors, and output them in a single error message
after the loop completes, resolving the warning and avoiding
popup hell by outputting a seperate message for each error.

691c817b34 Add util::Ref class as temporary alternative for c++17 std::any (Russell Yanofsky)
Pull request description:
This PR removes the `g_rpc_node` global, to get same benefits we see removing other globals and make RPC code more testable, modular, and reusable.
This uses a hybrid of the approaches suggested in #17548. Instead of using `std::any`, which isn't available in c++11, or `void*`, which isn't type safe, it uses a small new `util::Ref` helper class, which acts like a simplified `std::any` that only holds references, not values.
Motivation for writing this was to provide an simpler alternative to #18647 by Harris Brakmić (brakmic) which avoids some shortcomings of that PR (https://github.com/bitcoin/bitcoin/pull/18647#issuecomment-617878826)

This commit adds the configuration option handling. Future commits
add compact block serving and service bits signaling.
faec063887 log: Use Join() helper when listing log categories (MarcoFalke)
Pull request description:
This removes the global `ListLogCategories` and replaces it with a one-line member function `LogCategoriesString`, which just calls `Join`.
Should be a straightforward refactor to get rid of a few LOC.

Pull request description:
This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11):
Parent PR: #15606
Issue: #15605
Specification: https://github.com/jamesob/assumeutxo-docs/tree/master/proposal
---
This changeset introduces `ChainstateManager`, which is responsible for creating and managing access to multiple chainstates. Until we allow chainstate creation from UTXO snapshots (next assumeutxo PR?) it's basically unnecessary, but it is a prerequisite for background IBD support.
Changes are also made to the initialization process to make use of `g_chainman` and thus clear the way for multiple chainstates being loaded on startup.
One immediate benefit of this change is that we no longer have the `g_blockman` global, but instead have the ChainstateManager inject a reference of its shared BlockManager into any chainstate it creates.
Another immediate benefit is that uses of `ChainActive()` and `ChainstateActive()` are now covered by lock annotations. Because use of `g_chainman` is annotated to require cs_main, these two functions subsequently follow.
Because of whitespace changes, this diff looks bigger than it is. E.g., 4813167d98 is most easily reviewed with
```sh
git show --color-moved=dimmed_zebra -w 4813167d98

7fcdec0f32 Remove PID file at the very end (Hennadii Stepanov)
Pull request description:
While reproducing the bug from #18517, I've noticed that the `bitcoind.pid` file has already been removed when the `bitcoind` hangs.
This PR makes `Shutdown()` keep the `bitcoind.pid` file available until the end.

621e86ee8d Update -blocksonly documentation (glowang)
Pull request description:
When -blocksonly is set to 1, it interacts with the -walletbroadcast
parameter and sets it to 0.
This behavior is not captured by the current documentation, which
claims that -blocksonly does not impact any wallet transactions at
all.

parameter and sets it to 0 if it has not been set already.This behavior
is not captured by the current documentation, which claims that -blocksonly
does not impact any wallet transactions.
Update the max number of outgoing peers from 8 to 10, due to the
addition of two -blocksonly peers.

1168394d75 [wallet] Notify conflicted transactions in TransactionRemovedFromMempool (John Newbery)
Pull request description:
These boost signals were added in #9371, before we had a `TransactionRemovedFromMempool` method in the validation interface. The `NotifyEntryAdded` callback was used by validation to build a vector of conflicted transactions when connecting a block, which the wallet was notified of in the `BlockConnected` CValidationInterface callback.
Now that we have a `TransactionRemovedFromMempool` callback, we can fire that signal directly from the mempool for conflicted transactions.
Note that #9371 was implemented to ensure `-walletnotify` events were fired for these conflicted transaction. We inadvertently stopped sending these notifications in #16624 (Sep 2019 commit 7e89994). We should probably fix that, but in a different PR.

I'd previously attempted to create a specialized lock for ChainstateManager,
but it turns out that because that lock would be required for functions like
ChainActive() and ChainstateActive(), it created irreconcilable lock inversions
since those functions are used so broadly throughout the codebase.
Instead, I'm just using cs_main to protect the contents of g_chainman.

NotifyEntryAdded never had any subscribers so can be removed.
Since ConnectTrace no longer subscribes to NotifyEntryRemoved, there are
now no subscribers.
The CValidationInterface TransactionAddedToMempool and
TransactionRemovedFromMempool methods can now provide this
functionality. There's no need for a special notifications framework for
the mempool.
Calling interrupt_all() will immediately stop the scheduler, so it's
safe to invoke stop() beforehand, and this removes the reliance on boost
to interrupt serviceQueue().
and update feature_asmap.py and test_runner.py
This commit moves the asmap init.cpp code from the end of "Step 12: start node"
to "Step 6: network initialization" to provide feedback on passing an -asmap
config arg much more quickly. This change speeds up the feature_asmap.py
functional test file from 60 to 5 seconds by accelerating the 2 tests that use
`assert_start_raises_init_error`.
Credit to Wladimir J. van der Laan for the suggestion.
- move asmap #includes to sorted positions in addrman and init (move-only)
- remove redundant quotes in asmap InitError, update test
- remove full stops from asmap logging to be consistent with debug logging,
update tests
