aaaa055ff7 fuzz: Add option to merge input dir to test runner (MarcoFalke)
fa4fa88d76 doc: Remove --disable-ccache from docs (MarcoFalke)

Pull request description:

  This is mainly useful for myself to merge pull requests like https://github.com/bitcoin-core/qa-assets/pull/4

  I thought it wouldn't hurt to share the code.

  Also remove the `--disable-ccache` from the docs to speed up builds when developing fuzzers.

Merge #18350: test: Fix mining to an invalid target + ensure that a new block has the correct hash internally
7a6627ae87 Fix mining to an invalid target + ensure that a new block has the correct hash internally in Python tests (Samer Afach)

Pull request description:

  Test with block 47 in the `feature_block.py` creates a block with a hash higher than the target, which is supposed to fail. Now two issues exist there, and both have low probability of showing up:

  1. The creation is done with `while (hash < target)`, which is wrong, because hash = target is a valid mined value based on the code in the function `CheckProofOfWork()` that validates the mining target:
  ```
      if (UintToArith256(hash) > bnTarget)
          return false;
  ```
  2. As we know the hash stored in CBlock class in Python is stateful, unlike how it's in C++, where calling `CBlock::GetHash()` will actively calculate the hash and not cache it anywhere. With this, blocks that come out of the method `next_block` can have incorrect hash value when `solve=False`. This is because the `next_block` is mostly used with `solve=True`, and solving does call the function `rehash()` which calculates the hash of the block, but with `solve=False`, nothing calls that method. And since the work to be done in regtests is very low, the probably of this problem showing up is very low, but it practically happens (well, with much higher probability compared to issue No. 1 above).

  This PR fixes both these issues.

Pull request description:

  The wallet rebroadcast functionality learns about new blocks via the validation interface queue. To avoid test failures such as https://ci.appveyor.com/project/DrahtBot/bitcoin/builds/31119387#L466 , we can sync with the queue before advancing the test.

306f71b4eb scheduler: don't rely on boost interrupt on shutdown (Anthony Towns)

Pull request description:

  Replacing boost functionality with C++11 stuff.

  Motivated by #18227, but should stand alone. Changing from `boost::condition_var` to `std::condition_var` means `threadGroup.interrupt_all` isn't enough to interrupt `serviceQueue` anymore, so that means calling `stop()` before `join_all()` is needed. And the existing reverselock.h code doesn't work with sync.h's DebugLock code (because the reversed lock won't be removed from `g_lockstack` which then leads to incorrect potential deadlock warnings), so I've replaced that with a dedicated class and macro that's aware of our debug lock behaviour.

  Fixes #16027, Fixes #14200, Fixes #18227

Pull request description:

  This PR builds on PR #16702 to add functional tests / sanity checks and user-facing refinements for passing `-asmap` to configure ASN-based IP bucketing in addrman. As per our review discussion in that PR, the idea here is to handle aspects like functional tests and config arg handling that can help the PR be merged while enabling the author to focus on the bucketing itself.

  - [x] add feature functional tests to verify node behaviour and debug log output when launching

    - `bitcoind` with no `-asmap` arg

    - `bitcoind -asmap=RELATIVE_FILENAME` to the unit test data skeleton asmap

    - `bitcoind -asmap` with no filename specified using the default asmap file

    - `bitcoind -asmap` with no filename specified and a missing default asmap file

  - [x] add the ability to pass absolute path filenames to the `-asmap` config arg in addition to datadir-relative path filenames as per https://github.com/bitcoin/bitcoin/pull/16702#discussion_r361300447, and add test coverage

  - [x] separate the asmap file finding and parsing checks, which allows adding tests for the case of a found but unparseable or empty asmap

  - [x] add test for an empty asmap

  - [x] various asmap fixups

  - [x] move the asmap init code earlier in the init process to provide immediate feedback when passing an  `-asmap` config arg. This speeds up the `feature_asmap` functional test from 60 to 5 seconds! Credit to Wladimir J. van der Laan for the suggestion.

init: move asmap code earlier in init process
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`.

logging: asmap logging and #include fixups
- 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

test: add functional test for an empty, unparsable asmap
This is now testable after separating the asmap finding and parsing checks in
the previous commit.

test: add feature_asmap functional tests
to verify node behaviour and debug log when launching bitcoind in these cases:

1. `bitcoind` with no -asmap arg, using /16 prefix for IP bucketing

2. `bitcoind -asmap=<relative path>`, using the unit test skeleton asmap

3. `bitcoind -asmap/-asmap=` with no file specified, using the default asmap

4. `bitcoind -asmap` with no file specified, and a missing default asmap file

The tests are order-independent. The slowest test (missing default asmap file)
is placed last.

Merge #18224: Make AnalyzePSBT next role calculation simple, correct
1ef28b4f7c Make AnalyzePSBT next role calculation simple, correct (Gregory Sanders)

Pull request description:

  Sniped test and alternative to https://github.com/bitcoin/bitcoin/pull/18220

  Sjors documenting the issue:
  ```
  A PSBT signed by ColdCard was analyzed as follows (see #17509 (comment))

  {
    "inputs": [
      {
        "has_utxo": true,
        "is_final": false,
        "next": "finalizer"
      }
    ],
    "estimated_vsize": 141,
    "estimated_feerate": 1e-05,
    "fee": 1.41e-06,
    "next": "signer"
  }
  I changed AnalyzePSBT so that it returns "next": "finalizer" instead.
  ```

  It makes it much clearer that the role has been decided before hitting the `calc_fee` block, and groups all state-deciding in one spot instead of 2.

  Note that this assumes that PSBT roles are a complete ordering, which for now and in the future seems to be a correct assumption.
