7e3dbe4180cbeb65e59b53d9fa98509e9189549d wallet: Write best block to disk before backup (Fabian Jahr)

Pull request description:

  I discovered that we don't write the best block to disk when trying to explain the behavior described here: https://github.com/bitcoin/bitcoin/pull/30455#discussion_r1719951882

  In the context of that test, the behavior is confusing and I think it also shows that one of the already existing tests in `wallet_assumeutxo.py` doesn't actually test what it says. It only fails because the best block isn't written and actually, the height of the backup that is loaded is at the snapshot height during backup. So it really shouldn't fail since it's past the background sync blocks already.

  I'm not sure if this is super relevant in practice though so I am first looking for concept ACKs on the `BackupWallet` code change. Either way, I think this behavior should be documented better if it is left as is and the test should be changed.

89a8f74bbbb900abfb3d8e946eea18ad7b1513ad refactor: rename BlockKey to BlockRef (Sjors Provoost)

Pull request description:

  This continues the work in #30200 so that a future Stratum v2 Template Provider (see #29432) can avoid accessing node internals. It needs to know when a new block arrives in order to push new templates to connected clients.

  `waitTipChanged()` uses a new kernel notification `notifications().m_tip_block_mutex`, which this PR also introduces (a previous version used `g_best_block`).

  In order to ensure the new method works as intended, the `waitfornewblock`, `waitforblock` and `waitforblockheight` RPC methods are refactored to use it. This allows removing `RPCNotifyBlockChange`.

  There's a commit to add (direct) tests for the methods that are about to be refactored:
  - `waitfornewblock` was already implicitly tested by `feature_shutdown.py`.
  - `waitforblockheight` by `feature_coinstatsindex.py` and `example_test.py`

  This PR renames `getTipHash()` to `getTip()` and returns a `BlockRef` (renamed from `BlockKey`) so that callers can use either the height or hash.

  The later commits make trivial improvements to the `waitfor*` RPC calls (not needed for this PR).

  The `waitTipChanged()` method could probably also be used for the longpoll functionality in `getblocktemplate`, but I'm a bit reluctant to touch that.

  `RPCServer::OnStarted` no longer does anything and `RPCServer::OnStopped` merely prints a log statement. They were added in #5711 as a refactor. This PR drops them entirely.

  Finally `g_best_block` is also dropped.

Pull request description:

Pull request description:

  Running a CLI command when multiple wallets are loaded and `-rpcwallet` is not specified, should return a clearer error.

  Currently in `master`:

  ```
  $ bitcoin-cli -regtest -generate 1
  error code: -19
  error message:
  Wallet file not specified (must request wallet RPC through /wallet/<filename> uri-path).
  Try adding "-rpcwallet=<filename>" option to bitcoin-cli command line.
  ```

  With this change:

  ```
  $ bitcoin-cli -regtest -generate 1
  error code: -19
  error message:
  Multiple wallets are loaded. Please select which wallet to use by requesting the RPC through the /wallet/<walletname> URI path. Or for the CLI, specify the "-rpcwallet=<walletname>" option before the command (run "bitcoin-cli -h" for help or "bitcoin-cli listwallets" to see which wallets are currently loaded).

Pull request description:

  This changes all logging (including the wallet logging) to produce a
  `ConstevalFormatString` at compile time, so that the format string can be
  validated at compile-time.

  I tested with `clang` and found that the compiler will use less than 1% more of time and memory.

  When an error is found, the compile-time error depends on the compiler, but it may look similar to:

  ```
  src/util/string.h: In function ‘int main(int, char**)’:
  src/bitcoind.cpp:265:5:   in ‘constexpr’ expansion of ‘util::ConstevalFormatString<1>(((const char*)"Hi %s %s"))’
  src/util/string.h:38:98:   in ‘constexpr’ expansion of ‘util::ConstevalFormatString<1>::Detail_CheckNumFormatSpecifiers(std::basic_string_view<char>(((const char*)((util::ConstevalFormatString<1>*)this)->util::ConstevalFormatString<1>::fmt)))’
  src/util/string.h:78:34: error: expression ‘<throw-expression>’ is not a constant expression
     78 |         if (num_params != count) throw "Format specifier count must match the argument count!";
        |                                  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  ```

  This refactor does not change behavior of the compiled executables.

Pull request description:

  Fixes #20978

  If a block was pruned, `getblock` already returns a specific error: "Block not available (pruned data)".
  But if we haven't received the full block yet (e.g. in a race with block downloading after a new block was received headers-first, or during IBD) we just return an unspecific "Block not found on disk" error and log
  `ERROR: ReadBlockFromDisk: OpenBlockFile failed for FlatFilePos(nFile=-1, nPos=0) `
  which suggest something went wrong even though this is a completely normal and expected situation.

  This PR improves the error message and stops calling `ReadRawBlockFromDisk()`, when we already know from the header that the block is not available on disk.
  Similarly, it prevents all other rpcs from calling blockstorage read functions unless we expect the data to be there, so that `LogError()` will only be thrown when there is an actual file system problem.

  I'm not  completely sure if the cause is important enough to change the wording of the rpc error, that some scripts may rely on.
  If reviewers prefer it, an alternative solution would be to keep returning the current "Block not found on disk" error, but return it immediately instead of calling `ReadRawBlockFromDisk`, which would at least prevent the log error and also be an improvement in my opinion.

Pull request description:

  Follow-up to #30817 which covered the robustness of `dumptxoutset`: network is deactivated during the run but re-activated even when an issue was encountered. But it did not cover the case if the user had deactivated the network themselves before. In that case the user may want the network to stay off so the network is not reactivated after `dumptxoutset` finishes. A test for this behavior is added here.

6a1aa510e3 rpc: check block index before reading block / undo data
This avoids low-level log errors that are supposed to only occur when
there is an actual problem with the block on disk missing unexpectedly,
but not in the case where the block and/or undo data are expected not to be there.

It changes behavior such that in the first case (block index indicates
data is available but retrieving it fails) an error is thrown.

It also adjusts a functional tests that tried to simulate not
having undo data (but having block data) by deleting the undo file.
This situation should occur reality because block and undo data are pruned together.
Instead, test this situation with a block that hasn't been connected.

  It seems like there is a race where the block is stored locally and `getblock` does not error anymore, but `ActivateBestChain` has not finished yet, so the local services are not updated yet either. Fix this by waiting for the local services to update.

  Can be reproduced locally by adding the sleep here:

fae7b83eb58d22ed83878561603991131372cdd7 lint: Remove forbidden functions from lint-format-strings.py (MarcoFalke)

Pull request description:

  The `test/lint/lint-format-strings.py` was designed to count the number of format specifiers and assert that they are equal to the number of parameters passed to the format function. The goal seems reasonable, but the implementation has many problems:

  * It is written in Python, meaning that C++ code can not be parsed correctly. Currently it relies on brittle regex and string parsing.
  * Apart from the parsing errors, there are also many logic errors. For example, `count_format_specifiers` allows a mix of positional specifiers and non-positional specifiers, which can lead to runtime format bugs. Also, `count_format_specifiers` silently skipped over "special" format specifiers, which are valid in tinyformat, which again can lead to runtime format bugs being undetected.
  * The brittle logic has a history of breaking in pull requests that are otherwise fine. This causes the CI to fail and the pull request being blocked from progress until the bug in the linter is fixed, or the code is rewritten to work around the bug.
  * It is only run in the CI, or when the developer invokes the script. It would be better if the developer got the error message at compile-time, directly when writing the code.

  Fix all issues by using a `consteval` checked format string in `FatalErrorf` and `LogConnectFailure`.

  This is the first step toward https://github.com/bitcoin/bitcoin/issues/30530 and a follow-up will apply the approach to the other places.

72b46f28bf8d37a166961b5aa2a22302b932b756 test: fix exclude parsing for functional runner (Max Edwards)

Pull request description:

  This restores previous behaviour of being able to exclude a test by name without having to specify .py extension.

  It was noticed in https://github.com/bitcoin/bitcoin/issues/30851 that tests were no longer being excluded.

  PR https://github.com/bitcoin/bitcoin/pull/30244 introduced being able to exclude a specific tests based on args (such as `--exclude "rpc_bind.py --ipv6`) but it made the wrong assumption that test names intended to be excluded would include the .py extension.

  The following https://github.com/bitcoin/bitcoin/pull/30244#issuecomment-2344009687 shows that this is not how the `--exclude` flag was used in CI.

  https://github.com/bitcoin/bitcoin/pull/30244#issuecomment-2344009687 gave three examples of `--exclude` being used in CI so I compared the number of tests that the runner would run for these three examples in three situations, before #30244 was introduced, in master today and with this PR applied.

  Example:

  `--previous-releases --coverage --extended --exclude feature_dbcrash`

  Test count:
  Before #30244 introduced: 314
  Master: 315
  With this PR: 314

  Example:

  `--exclude feature_init,rpc_bind,feature_bind_extra`

  Test count:
  Before #30244 introduced: 306
  Master 311
  With this PR: 306

  Example:

  `--exclude rpc_bind,feature_bind_extra`

  Before #30244 introduced:  307
  Master 311
  With this PR: 307

  I've also tested that the functionality introduced with #30244 remains and we can still exclude specific tests by argument.

Merge bitcoin/bitcoin#30807: Fix peers abruptly disconnecting from AssumeUTXO nodes during IBD
992f83bb6f4b29b44f4eaace1d1a2c0001d43cac test: add coverage for assumeUTXO honest peers disconnection (furszy)
6d5812e5c852c233bd7ead2ceef051f8567619ed assumeUTXO: fix peers disconnection during sync (furszy)

Pull request description:

  Because AssumeUTXO nodes prioritize tip synchronization, they relay their local
  address through the network before completing the background chain sync.
  This, combined with the advertising of full-node service (`NODE_NETWORK`), can
  result in an honest peer in IBD connecting to the AssumeUTXO node (while syncing)
  and requesting an historical block the node does not have. This behavior leads to
  an abrupt disconnection due to perceived unresponsiveness from the AssumeUTXO
  node.

  This lack of response occurs because nodes ignore `getdata` requests when they do
  not have the block data available (further discussion can be found in #30385).

  Fix this by refraining from signaling full-node service support while the
  background chain is being synced. During this period, the node will only
  signal `NODE_NETWORK_LIMITED` support. Then, full-node (`NODE_NETWORK`)
  support will be re-enabled once the background chain sync is completed.

  Thanks mzumsande for a post-#30385 convo too.

  Testing notes:
  Just cherry-pick the second commit (bb08c22) on master.
  It will fail there, due to the IBD node requesting historical blocks to the snapshot
  node - which is bad because the snapshot node will ignore the requests and
  stall + disconnect after some time.

test: add coverage for assumeUTXO honest peers disconnection
Exercising and verifying the following points:

1. An IBD node can sync headers from an AssumeUTXO node at
   any time.

2. IBD nodes do not request historical blocks from AssumeUTXO
   nodes while they are syncing the background-chain.

3. The assumeUTXO node dynamically adjusts the network services
   it offers according to its state.

4. IBD nodes can fully sync from AssumeUTXO nodes after they
   finish the background-chain sync.

c2b779da4e7f1bf1a5c5d67ec94cba3027b42ee7 refactor: Manage dumptxoutset RAII classes with std::optional (Fabian Jahr)
4b5bf335adabd1586043caa72a98356a8255bc29 test: Add coverage for failing dumptxoutset behavior (Fabian Jahr)

Pull request description:

  This adds a test that checks that network activity is not suspended if dumptxoutset fails in the middle of its process which is implemented with the `NetworkDisable` RAII class. I would have liked to add coverage for the `TemporaryRollback` RAII class but that seems a lot more tricky since the failure needs to happen at some point after the rollback and on the scale of our test chain here I couldn't find a way to do it yet. This was requested by pablomartin4btc here: https://github.com/bitcoin/bitcoin/pull/30808#pullrequestreview-2280450117. To test the test you can comment out the content of the destructor of `NetworkDisable`.

  It also addresses the feedback by ryanofsky to use `std::optional` instead of `std::unique_ptr` for the management of the RAII object: https://github.com/bitcoin/bitcoin/pull/30808#discussion_r1744149228

ee47ca29d6ef55650a0af63bca817c5d494f31ef init: fix fatal error on '-wallet' negated option value (furszy)

Pull request description:

  Currently, if users provide a double negated value such as '-nowallet=0' or a non-boolean
  convertible value to a negated option such as '-nowallet=not_a_boolean', the initialization
  process results in a fatal error, causing an unclean shutdown and displaying a poorly
  descriptive error message:
  "JSON value of type bool is not of expected type string." (On bitcoind. The GUI
  does not display any error msg - upcoming PR -).

  This PR fixes the issue by ensuring that only string values are returned in the
  the "wallet" settings list, failing otherwise. It also improves the clarity of the
  returned error message.

  Note:
  This bug was introduced in https://github.com/bitcoin/bitcoin/pull/22217. Where the `GetArgs("-wallet")` call was
  replaced by `GetSettingsList("-wallet")`.

ecc98ccff25b7e758337e764e59d764076772fec test: add cases for blank rpcauth (tdb3)

Pull request description:

  The current `rpcauth` parsing behavior is inconsistent and unintuitive (see https://github.com/bitcoin/bitcoin/pull/29141#issuecomment-1972085251 and additional details below).
  The current behavior inconsistently treats empty `rpcauth` as an error (or not) depending on the location within CLI/bitcoin.conf and the location of adjacent valid `rpcauth` params.

  Empty `rpcauth` is now consistently treated as an error and prevents bitcoind from starting.
  Continuation of the upforgrabs PR #29141.

  ### Additional details:
  Current `rpcauth` behavior is nonsensical:

   - If an empty `rpcauth` argument was specified as the last command line argument, it would cause all other `rpcauth` arguments to be ignored.
   - If an empty `rpcauth` argument was specified on the command line followed by any nonempty `rpcauth` argument, it would cause an error.
   - If an empty `rpcauth=` line was specified after non-empty rpcauth line in the config file it would cause an error.
   - If an empty `rpcauth=` line in a config file was first it would cause other rpcauth entries in the config file to be ignored, unless there were `-rpcauth` command line arguments and the last one was nonempty, in which case it would cause an error.

  New behavior is simple:
   - If an empty rpcauth config line or command line argument is used it will cause an error

8131bf7483c0ea10d3573c9f2e977d19d8569b7f ci: parse TEST_RUNNER_EXTRA into an array (Max Edwards)
c4762b0aa06f2654d108bc7ca05887ffd88cf6f8 test: allow excluding func test by name and arg (Max Edwards)

Pull request description:

  While working on CI I wanted to disable some functional tests so I used the `TEST_RUNNER_EXTRA` var. The problem I had was tests that have flags such as `rpc_bind.py --ipv6` must be passed in quotes otherwise the `--ipv6` portion will be considered an argument to `test_runner.py` rather than a test name.

  This change allows proper parsing of quotes and complex values such as:

  ```shell
  TEST_RUNNER_EXTRA='--exclude "rpc_bind.py --ipv6,feature_proxy.py"'
  ```

  Update:

  While testing this it was noticed that `test_runner.py` when given `--exclude "rpc_bind.py --ipv6"` will exclude all `rpc_bind.py` tests so this PR has been updated to include a change to the test runner to only exclude the specific test if you pass an arg or exclude all tests of that name if you do not pass an arg. `--exclude rpc_bind.py` will exclude all three variants and `--exclude rpc_bind --ipv6` will only exclude the IPV6 variant.

Pull request description:

  The checks have many issues:

  * Some checks that could in theory hide bugs are not applied -> Fix them and apply them going forward
  * Some checks are redundant Python 2 checks, or of low value -> Remove them
  * The checks are slow -> Speed them up from ~10 seconds to about ~20 milliseconds

Pull request description:

  Refactors the code a bunch, and adds `--poolnum` / `--poolid` options so that signers can tag their coinbases in a way that explorers can recognise (see also https://github.com/bitcoin-data/mining-pools/pull/82 and https://github.com/mempool/mempool/issues/2903).

  The refactoring in particular helps enable the "try using inquisition's getblocktemplate, and if that doesn't work fall back to core's getblocktemplate" logic, as described/implemented in https://github.com/bitcoin-inquisition/bitcoin/pull/7

Merge bitcoin/bitcoin#29605: net: Favor peers from addrman over fetching seednodes
6eeb188d40fe8f6c3b0a3be6dca519ea9a7b2358 test: adds seednode functional tests (Sergi Delgado Segura)
3270f0adad6ccbb8c004fb222f420e9b3ea32ea6 net: Favor peers from addrman over fetching seednodes (Sergi Delgado Segura)

Pull request description:

  This is a follow-up of #28016 motivated by https://github.com/bitcoin/bitcoin/pull/28016#pullrequestreview-1913140932 and https://github.com/bitcoin/bitcoin/pull/28016#issuecomment-1984448937.

  The current behavior of seednode fetching is pretty eager: we do it as the first step under `ThreadOpenNetworkConnections` even if some peers may be queryable from our addrman. This poses two potential issues:

  - First, if permanently set (e.g. running with seednode in a config file) we'd be signaling such seed every time we restart our node
  - Second, we will be giving the seed node way too much influence over our addrman, populating the latter with data from the former even when unnecessary

  This changes the behavior to only add seednodes to `m_addr_fetch` if our addrman is empty, or little by little after we've spent some time trying addresses from our addrman. Also, seednodes are added to `m_addr_fetch` in random order, to avoid signaling the same node in case more than one seed is added and we happen to try them over multiple restarts
