Merge bitcoin/bitcoin#26970: test: fix immediate tx relay in wallet_groups.py
ab4efad51b9ba276ffeb6871931e13772493f7cc test: fix immediate tx relay in wallet_groups.py (Sebastian Falbesoner)

Pull request description:

  In the functional test wallet_groups.py we whitelist peers on all nodes (`-whitelist=noban@127.0.0.1`) to enable immediate tx relay for fast mempool synchronization. However, considering that this setting only applies to inbound peers and the default test topology looks like this:
  ```
      node0 <--- node1 <---- node2 <--- ... <-- nodeN
  ```

  txs propagate fast only from lower- to higher-numbered nodes (i.e. "left to right" in the above diagram) and take long from higher- to lower-numbered nodes ("right to left") since in the latter direction we only have outbound peers, where the trickle relay is still active. As a consequence, if a tx is submitted from any node other than node0, the mempool synchronization can take quite long.

  This PR fixes this by simply adding another connection from node0 to the last node, leading to a ~2-3x speedup (5 runs measured via `time ./test/functional/wallet_groups.py` are shown):

  Note that in most tests this is not a problem since txs very often originate from node0.

  - generate 101 blocks instead of 110
  - move `sync_all` call into the loop, so fewer blocks are synced on each call, to hopefully see fewer CI timeouts as in https://bitcoinbuilds.org/index.php?ansilog=88eee99e-1727-44ed-b778-3b9c75c33928.log

Pull request description:

  There are still many functional tests that perform conversions from a hex-string to a message object (deserialization) manually. This PR identifies all those instances and replaces them with a newly introduced helper `tx_from_hex`.

  Instances were found via
  * `git grep "deserialize.*BytesIO"`

  and some of them manually, when it were not one-liners.

  Further, the helper `ToHex` was removed and simply replaced by `.serialize().hex()`, since now both variants are in use (sometimes even within the same test) and using the helper doesn't really have an advantage in readability. (see discussion https://github.com/bitcoin/bitcoin/pull/22257#discussion_r652404782)

Merge #14582: wallet: always do avoid partial spends if fees are within a specified range
7f13dfb587dd6a7a5b7dfbfe689ae0ce818fe5c9 test: test the implicit avoid partial spends functionality (Karl-Johan Alm)
b82067bf696c53f22536f9ca2e51949c164f6b06 wallet: try -avoidpartialspends mode and use its result if fees are below threshold (Karl-Johan Alm)

Pull request description:

  The `-avoidpartialspends` feature is normally disabled, as it may affect the optimal fee for payments. This PR introduces a new parameter `-maxapsfee` (max avoid partial spends fee) which acts on the following values:
  * -1: disable partial spend avoidance completely (do not even try it)
  * 0: only do partial spend avoidance if fees are the same or better as the regular coin selection
  * 1..∞: use APS variant if the absolute fee difference is less than or equal to the max APS fee

  For values other than -1, the code will now try partial spend avoidance once, and if that gives a value within the accepted range, it will use that.

  Example: -maxapsfee=0.00001000 means the wallet will do regular coin select, APS coin select, and then pick AKS iff the absolute fee difference is <= 1000 satoshi.

  Edit: updated this to reflect the fact we are now using a max fee.

Merge #19674: refactor: test: use throwaway _ variable for unused loop counters
dac7a111bdd3b0233d94cf68dae7a8bfc6ac9c64 refactor: test: use _ variable for unused loop counters (Sebastian Falbesoner)

Pull request description:

  This tiny PR substitutes Python loops in the form of `for x in range(N): ...` by `for _ in range(N): ...` where applicable. The idea is indicating to the reader that a block (or statement, in list comprehensions) is just repeated N times, and that the loop counter is not used in the body, hence using the throwaway variable. This is already done quite often in the current tests (see e.g. `$ git grep "for _ in range("`). Another alternative would be using `itertools.repeat` (according to Python core developer Raymond Hettinger it's [even faster](https://twitter.com/raymondh/status/1144527183341375488)), but that doesn't seem to be widespread in use and I'm not sure about a readability increase.

  The only drawback I see is that whenever one wants to debug loop iterations, one would need to introduce a loop variable again. Reviewing this is basically a no-brainer, since tests would fail immediately if a a substitution has taken place on a loop where the variable is used.

  Instances to replace were found by `$ git grep "for.*in range("` and manually checked.

    ACK dac7a111bdd3b0233d94cf68dae7a8bfc6ac9c64 -- the updated code is easier to reason about since the throwaway nature of a variable is expressed explicitly (using the Pythonic `_` idiom) instead of implicitly. Explicit is better than implicit was we all know by now :)

Pull request description:

  When writing tests, often includes need to be added or removed. Currently the list of includes is not sorted, so developers that write tests and have `clang-format` installed will either have an unrelated change (sorting) included in their commit or they will have to manually undo the sort.

  This pull preempts both issues by just sorting all includes in one commit.

  Please be aware that this is **NOT** a change to policy to enforce clang-format or any other developer guideline or process. Developers are free to use whatever tool they want, see also #18651.

  Edit: Also includes a commit to bump the copyright headers, so that the touched files don't need to be touched again for that.

  Edit: Goal of this PR is to replace integer constants with `COINBASE_MATURITY` but not necessarily in *all* cases because that would mean to read and fully understand all tests. That's out of my time constraints. Any reports where `COINBASE_MATURITY` should be used are welcome though!

Pull request description:

  Currently the test_runner would exit if the wallet was not compiled into the Bitcoin Core executable. However, a lot of the tests run without the wallet just fine and there is no need to globally require the wallet to run the tests.

  This is a bugfix, since wallet_dump currently uses the wrong name:

  18857b4c40/test/functional/wallet_dump.py (L89-L92)

  Rename all to the same name with a scripted diff (and some unrelated cleanups).

Merge #13054: tests: Enable automatic detection of undefined names in Python tests scripts. Remove wildcard imports.
68400d8b96 tests: Use explicit imports (practicalswift)

Pull request description:

  Enable automatic detection of undefined names in Python tests scripts. Remove wildcard imports.

  Wildcard imports make it unclear which names are present in the namespace, confusing both readers and many automated tools.

  An additional benefit of not using wildcard imports in tests scripts is that readers of a test script then can infer the rough testing scope just by looking at the imports.

Pull request description:

  This PR adds an optional (off by default) `-avoidpartialspends` flag, which changes coin select to use output groups rather than outputs, where each output group corresponds to all outputs with the same destination.

  It is a privacy improvement, as each time you spend some output, any other output that is publicly associated with the destination (address) will also be spent at the same time, at the cost of fee increase for cases where coin select without group restriction would find a more optimal set of coins (see example below).

  For regular use without address reuse, this PR should have no effect on the user experience whatsoever; it only affects users who, for some reason, have multiple outputs with the same destination (i.e. address reuse).

  Nodes with this turned off will still try to avoid partial spending, if the fee of the resulting transaction is not greater than the fee of the original transaction.

  Example: a node has four outputs linked to two addresses `A` and `B`:

  * 1.0 btc to `A`
  * 0.5 btc to `A`
  * 1.0 btc to `B`
  * 0.5 btc to `B`

  The node sends 0.2 btc to `C`. Without `-avoidpartialspends`, the following coin selection will occur:
  * 0.5 btc to `A` or `B` is picked
  * 0.2 btc is output to `C`
  * 0.3 - fee is output to (unique change address)

  With `-avoidpartialspends`, the following will instead happen:
  * Both of (0.5, 1.0) btc to `A` or `B` is picked (one or the other pair)
  * 0.2 btc is output to `C`
  * 1.3 - fee is output to (unique change address)

  As noted, the pro here is that, assuming nobody sends to the address after you spend from it, you will only ever use one address once. The con is that the transaction becomes slightly larger in this case, because it is overpicking outputs to adhere to the no partial spending rule.

  This complements #10386, in particular it addresses @luke-jr and @gmaxwell's concerns in https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-300667926 and https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-302361381.

  Together with `-avoidreuse`, this fully addresses the concerns in #10065 I believe.
