Use a supported Dash command in the release note

This example is unusable in every Dash build: a repo-wide search finds no bumpfee RPC registration (only historical comments), and configure.ac:35 defines the built client as dash-cli, not bitcoin-cli. Users following the new release note therefore get a missing executable or method; replace the example and method list with a supported RPC such as fundrawtransaction invoked through src/dash-cli.

Update the CI flake8 pins with the E721 fixes

In the checked lint provisioning, both ci/lint/04_install.sh:37 and contrib/containers/ci/ci-slim.Dockerfile:83 still install flake8 5.0.4, even though these edits are the source fixes required by flake8 6.1.0 and the backported upstream commit explicitly includes that version bump. Consequently CI continues running the old checker and does not enforce the newly expected E721 behavior; bump both synchronized pins to 6.1.0 or explicitly document this as a partial backport.

Wire the fuzz runner into a macOS CI job

Checked the src-mac path in .github/workflows/build.yml:435-447: it sets BUILD_TARGET=mac, which ci/dash/matrix.sh:39-40 maps only to the cross-build configuration; that configuration disables tests, and repo-wide search shows RUN_FUZZ_TESTS is only defined, never consumed by a CI script. Thus this new non-libFuzzer branch is never invoked on macOS and the bitcoin#27932 backport adds no advertised macOS fuzz coverage; add a native macOS invocation of test/fuzz/test_runner.py, or document/drop the partial backport.

Replace the Bitcoin-only examples with a Dash RPC example.

The examples invoke src/bitcoin-cli and bumpfee, but this change exposes the named-option form through Dash RPCs such as listunspent. A reader cannot use either command to try the documented feature. Show src/dash-cli -named listunspent minimumAmount=1 and the corresponding query_options form instead. Dash’s help examples use dash-cli. (raw.githubusercontent.com)

Do not cleanse Berkeley DB-owned key memory.

SafeDbt datKey has no DB_DBT_MALLOC flag. After get() returns a key, Berkeley DB can replace its pointer with Berkeley-managed memory. SafeDbt::~SafeDbt() then writes through that pointer to cleanse it. This also affects GetNewCursor(), because an empty prefix uses the same path. Use an owned result buffer, and keep any non-owned seek key separate from SafeDbt. (docs.oracle.com)

Exclude walletutil before running IWYU

In the checked linux64_multiprocess path, .github/workflows/build-src.yml:209-216 invokes this script, but this regexp does not match src/wallet/walletutil.cpp even though lines 99-102 explicitly declare it temporarily excluded. Removing the old source whitelist therefore sends that known-unready translation unit through iwyu_tool.py and fix_includes.py; add src/wallet/walletutil.cpp to the filter so the intended exclusion actually applies.

🔴 Blocking: Preserve the already-landed bitcoin#28123 help fix

This replacement reverses the help fix already landed in ed36fc7, an ancestor of the review base. The requests argument is an array, and the surviving RPCArg::ToString check in src/rpc/util.cpp:1147–1153 rejects quoted oneline descriptions for non-string arguments when -rpcdoccheck is enabled. As a result, help importmulti returns the internal-bug diagnostic instead of its documentation, and global help contains that diagnostic instead of the command summary. Upstream bitcoin#26485 changes only the adjacent options type here; its quoted requests text is unchanged context, not a change to backport. Preserve the base's unquoted description.

Resolved (re-reviewed at da28a1bd): Your importmulti definition now preserves the unquoted requests summary at line 1528. This removes the value rejected by the non-string argument check under rpcdoccheck.

🔴 Blocking: Preserve bitcoin#27932's macOS fuzz CI coverage

The advertised bitcoin#27932 backport omits its native macOS CI activation and the execution prerequisites needed to make that activation work in Dash. Upstream merge 3d51f7c adds RUN_FUZZ_TESTS=true and FUZZ_TESTS_CONFIG="--exclude banman" to ci/test/00_setup_env_mac_native_arm64.sh, using an existing 06_script_b.sh consumer to replay the corpus. Dash retains neither those settings nor a CI consumer of RUN_FUZZ_TESTS; its mac workflow instead selects the cross-build configuration through ci/dash/matrix.sh. Thus this runner capability does not provide the upstream macOS corpus-replay coverage. Complete the equivalent execution wiring in Dash's CI adaptation without adding a matrix job. If this area is intentionally excluded, explicitly narrow the advertised backport and link a tracking issue; the current PR description contains no such exclusion.

_{source: muse-spark-1.3-contributor (phase1-reviewer: general); gpt-6.1-sol (phase2-reviewer: general, backport-reviewer, dash-core-commit-history)}

Withdrawn (re-reviewed at 0d188488): Your check=False probe and standalone corpus-directory dispatch match upstream, and Dash's ordinary standalone harness supports that replay mode. I cannot substantiate a separate runner blocker; the missing macOS CI execution is retained only under 696d3b42bde0.

🟡 Suggestion: Retain bitcoin#27571's walletutil exclusion

Removing the IWYU whitelist now includes src/wallet/walletutil.cpp, although the new comment explicitly lists walletutil as temporarily excluded. Upstream merge 4c3d67a includes src/wallet/walletutil in this exact filter before broadening IWYU to all sources; the Dash adaptation drops that alternative. walletutil.cpp remains a compiled wallet source, so the omission changes the filtering behavior rather than merely leaving a stale comment. Restore the upstream exclusion, or establish why it is no longer needed for Dash. No resulting build failure is asserted.

_{source: muse-spark-1.3-contributor (phase1-reviewer: general); gpt-6.1-sol (phase2-reviewer: general, backport-reviewer, dash-core-commit-history)}

Withdrawn (re-reviewed at 0d188488): Your base already contains bitcoin#27759's wallet-header fixes, which are the same changes that let upstream remove its temporary walletutil exclusion. The current filter is therefore appropriate; the stale copied comment does not justify restoring an obsolete exclusion.

✅ Withdrawn at 0d188488; see the replies below.

🟡 Suggestion: Release note cites non-existent bumpfee and bitcoin-cli

Both new examples invoke src/bitcoin-cli and the bumpfee RPC, neither of which is available in Dash: configure.ac defines the client as dash-cli, and the source contains no bumpfee RPC registration. This leaves readers unable to try the documented feature. Remove bumpfee from the method list and replace both examples with a supported pair, such as src/dash-cli -named listunspent minimumAmount=1 and src/dash-cli -named listunspent query_options='{"minimumAmount":1}'. The listunspent declaration and CLI conversion table support both forms.

_{source: muse-spark-1.3-contributor (phase1-reviewer: general)}

Resolved (re-reviewed at da28a1bd): Your revised examples use dash-cli with listunspent, and both the direct coinType parameter and nested query_options form are supported by the current RPC definition and conversion table. The unsupported bumpfee entry is also removed.

Withdrawn (re-reviewed at 0d188488): Your release note already uses supported dash-cli/listunspent examples at both the supplied prior head and the current head. I am withdrawing the stale report rather than asking you to change documentation that is already correct.

🔴 Blocking: Adapt Dash type-comment imports for the bitcoin#28194 lint upgrade

The upgrade from flake8 5.0.4 to 6.1.0 leaves Dash-specific imports incompatible with the new checker. CI run 41651190122, job 125993768620, fails lint-python.py with F401 for MasternodeInfo in feature_governance.py, feature_llmq_connections.py, feature_llmq_singlenode.py, feature_mnehf.py and interface_zmq_dash.py. In those files the name appears only in loop type comments, which the newer checker does not count as import uses. Remove the unused imports or replace the comments with supported typing constructs, retaining the synchronized flake8 pins. This is a demonstrated validation regression from the tool upgrade, not merely a request for stylistic cleanup.

_{source: gpt-6.1-sol (phase2-reviewer: general, backport-reviewer, dash-core-commit-history)}

Resolved (re-reviewed at 0d188488): You removed the comment-only MasternodeInfo imports and associated type comments from all five affected files since the supplied prior head. Both flake8 pins remain at 6.1.0, and the current-head lint check passes.

Withdrawn (re-reviewed at 2552f141): Both pins are 6.1.0 and the five Dash-specific tests remove the unused imports with their loop type comments. I verified these adaptations were already present at bc1963c as well, so the original blocker was unsupported at the prior reviewed head rather than a newly fixed defect.

✅ Withdrawn at bc1963cb; see the replies below.

🟡 Suggestion: Preserve bitcoin#27932's macOS fuzz CI coverage

These exports reproduce upstream's configuration additions but do not enable corpus replay in Dash CI. Upstream's native macOS job selects the modified environment and ci/test/06_script_b.sh consumes RUN_FUZZ_TESTS and FUZZ_TESTS_CONFIG to launch the runner. Dash's mac-build job instead selects 00_setup_env_mac_cross.sh through ci/dash/matrix.sh, and no checked CI execution script consumes these settings. All four upstream changed areas have counterparts in this backport; the remaining defect is the ineffective CI adaptation, not an omitted production API or a demonstrated runtime failure. Adapt an existing appropriate job to execute macOS replay without adding a matrix job, or explicitly document the partial coverage and link a tracking issue before deferring it.

_{source: gpt-6.1-sol (phase2-reviewer: general)}

These exports are kept so the env file stays identical to upstream and later backports apply cleanly. Dash CI never replays the fuzz corpus on any platform: no script in ci/dash or .github/workflows calls test/fuzz/test_runner.py or reads RUN_FUZZ_TESTS, not even for linux64_fuzz, and no workflow selects 00_setup_env_mac_native.sh. Adding macOS corpus replay would be a new CI feature, not part of this backport. The bitcoin#27932 code changes (test_runner.py, rpc.cpp, config.ini.in) are fully included.

You're right: linux64_fuzz only builds the fuzz executable, and Dash's CI has no corpus-replay consumer for these settings; that gap predates this backport. The runner/config/RPC changes are present, and enabling macOS replay would require new CI execution wiring rather than preserving coverage Dash already had. I overstated this as a backport defect and withdraw the finding; no tracking issue is required to lift it.

Withdrawing this finding.

Withdrawn (re-reviewed at bc1963cb): Your explanation is confirmed by the execution scripts: Dash CI does not consume RUN_FUZZ_TESTS or replay the corpus on Linux either, and this backport includes all four upstream changed areas. Adding macOS corpus execution would introduce new Dash CI behavior, so this finding remains withdrawn.

🔴 Blocking: Adapt the portable bitcoin#26485 tests from excluded suites

The advertised full bitcoin#26485 backport still omits two portable upstream test transformations. Upstream merge 34ac3f4 changes wallet_bumpfee.py:308 from listunspent(query_options={'minimumAmount': fee}) to listunspent(minimumAmount=fee), and wallet_taproot.py:381 from sendall(..., options={'psbt': True}) to sendall(..., psbt=True). Both operations are supported by Dash independently of RBF or Taproot. At this head, functional listunspent query-filter calls still use query_options, and no functional sendall call passes the named psbt option, so neither transformation has equivalent coverage. The PR description contains no explicit exclusion for these hunks. Preserve their coverage in existing suites—for example, adapt a minimumAmount call in wallet_basic.py and add an explicit named psbt case in wallet_sendall.py—without importing the unsupported subsystems. This is a full-backport completeness blocker, not evidence of a production runtime failure.
