**: # CodeRabbit AI Review Instructions for Dash BackportsYour Role
You are reviewing Bitcoin Core backports to Dash Core. Your ONLY job is to validate that the Dash commit faithfully represents the original Bitcoin commit with minimal, necessary adaptations.
Critical Validation Rules
1. File Operations Must Match (AUTO-REJECT if violated)
- If Bitcoin modifies an existing file → Dash MUST modify (not create new)
- If Bitcoin creates a new file → Dash creates
- If Bitcoin deletes a file → Dash deletes
- Common failure: Bitcoin modifies keys.txt, Dash creates new file with 58 keys
2. Size Ratio Check (80-150% of Bitcoin)
- Count functional lines changed (exclude comments/whitespace)
- Dash changes should be 80-150% of Bitcoin's size
- Red flag: 2-line Bitcoin fix becoming 150+ lines in Dash
3. No Scope Creep
- Reject if you see: "TODO:", "FIXME:", "while we're here", "also fix"
- No unrelated refactoring or style changes
- Only Bitcoin's intended changes + minimal Dash adaptations
4. Bitcoin-Specific Code Detection
- Auto-reject witness/segwit code:
msg_wtxidrelay,MSG_WTX, witness imports- Auto-reject RBF (replace-by-fee) functionality
- Note: PSBT is supported in Dash (don't flag)
5. Mandatory Adaptations Only
bitcoin→dashin strings/pathsBitcoin→Dashin user-facing text- Port numbers: 8332→9998 (RPC), 8333→9999 (P2P)
- Hardcoded test values specific to Dash
- No other changes unless absolutely required
6. Completeness Check
- All files changed in Bitcoin must be present
- Extra files need clear justification (Dash-specific compatibility)
- Missing files = incomplete backport
Review Process
- First: Check file operations match exactly
- Second: Calculate size ratio
- Third: Scan for scope creep patterns
- Fourth: Detect Bitcoin-specific code
- Fifth: Verify all changes are minimal adaptations

Learning: DashCoreAutoGuix successfully completed a complex Bitcoin Core backport (PR #29412) for block mutation detection by implementing the IsBlockMutated function, adding net processing integration, creating comprehensive unit tests, and properly adapting all Bitcoin-specific witness code for Dash compatibility. The backport maintains full security functionality while respecting Dash's non-witness transaction architecture.

Learning: During multiple verification attempts of Bitcoin Core commit 06d469c26b backport to Dash PR #566, DashCoreAutoGuix consistently identified scope creep in interface_usdt_utxocache.py where additional pruning test functionality was added beyond the original Bitcoin commit. The user provided comprehensive fixes including both scope creep removal and missing mempool test file additions, but couldn't push due to authentication restrictions. The scope creep fix was identified as the priority to resolve CI failures.

Learning: During Dash backport verification of Bitcoin Core commit 06d469c26b, scope creep was detected when additional pruning test functionality was added to interface_usdt_utxocache.py beyond what was in the original Bitcoin commit. The fix involved removing the extra test block while maintaining the core compiler flag fixes for USDT compilation errors.

38-39: LGTM - Type migration to std::chrono::millisecondsThe global timeout variable has been correctly migrated from an integer (representing milliseconds) to
std::chrono::millisecondswith a chrono literal20s. This aligns with the PR objective of using steady clock for duration measurements.
303-303: LGTM - Documentation updated for type-safe parameterComment appropriately simplified by removing "in milliseconds" since the parameter type
std::chrono::millisecondsis now self-documenting.
313-313: LGTM - Function signature updated for type-safe timeoutThe
InterruptibleRecvfunction signature correctly updated to acceptstd::chrono::millisecondsinstead ofint, providing type safety for timeout handling.
315-316: LGTM - Critical migration to steady clock for reliable timeoutsThis is the core change implementing the PR objective. The timing logic now uses
Now<SteadyMilliseconds>()(steady clock) instead of system clock, ensuring that socket timeouts are not affected by system time adjustments. This is particularly important for long-running operations like Tor proxy negotiations.
340-340: LGTM - Consistent steady clock usage in loopThe
curTimeupdate correctly usesNow<SteadyMilliseconds>()to maintain consistency with the steady clock approach throughout the timeout loop.
38-340: BACKPORT VALIDATION: PASSFile Operations: ✓ MATCH - Bitcoin modifies existing file, Dash modifies existing file
Size Ratio: Appropriate - 5 functional lines changed, all directly related to clock type migration
Scope Creep: ✓ NONE - All changes strictly related to migrating from system clock (int milliseconds) to steady clock (std::chrono::milliseconds)
Bitcoin-Specific Code: ✓ NONE - No witness, segwit, RBF, or other Bitcoin-specific features
Completeness: ✓ COMPLETE for this file - All timeout-related code in InterruptibleRecv and g_socks5_recv_timeout properly migrated
Changes Summary:
- Global timeout variable migrated to type-safe chrono duration
- Function signature updated for type safety
- Timing calculations switched from epoch-based to steady-time points
- Documentation updated appropriately
This is a faithful, minimal backport of Bitcoin Core PR bitcoin#27405 for the netbase.cpp component. The changes ensure socket timeouts are immune to system clock adjustments, which is critical for reliable network operations especially with slow proxies like Tor.

Use a standard chrono type; avoid undefined MillisecondsDouble
MillisecondsDouble may not exist in Dash’s util/time.h. Prefer std::chrono types:

auto start{SteadyClock::now()};
...

ConclusionThe backport is faithful to Bitcoin's changes, properly adapted for Dash, and builds successfully. The single CI failure appears to be a spurious timeout. All fixes applied were necessary and correct. Recommendation: Merge Automated verification by Dash backport agent |

Ideally we backport the pre-req instead of just adding this here.

…tate - Revert blockfilter_index_tests.cpp to use IndexWaitSynced() instead of inline timeout loop - Revert txindex_tests.cpp to use IndexWaitSynced() instead of inline timeout loop Bitcoin PR bitcoin#27405 changed existing timeout loops from GetTimeMillis() to SteadyClock::now(). However, Dash already has the refactored IndexWaitSynced() helper from Bitcoin PR bitcoin#27988, which was backported earlier. The timeout loop code is an intermediate Bitcoin state that Dash has already moved past, so we should not introduce it. The core changes from bitcoin#27405 (switching to steady clock) are still preserved in the other files where they are appropriate.

Verification Agent: Fixes Applied I've addressed the scope creep issues identified by @PastaPastaPasta. Changes MadeReverted test files to use IndexWaitSynced() instead of inline timeout loops:
RationaleBitcoin PR bitcoin#27405 changed existing timeout loops from GetTimeMillis() to SteadyClock::now(). However, Dash already has the refactored IndexWaitSynced() helper from Bitcoin PR bitcoin#27988 (backported earlier to Dash). The inline timeout loop code represents an intermediate Bitcoin state that Dash has already moved past. Introducing it would be scope creep - replacing a clean abstraction with implementation details. The core steady clock changes from bitcoin#27405 are preserved in all other files where they're appropriate (src/netbase.cpp, src/qt/clientmodel.cpp, src/wallet/wallet.cpp, etc.). Regarding MillisecondsDoubleThe MillisecondsDouble typedef in src/util/time.h is required for the wallet passphrase timing code to compile. While it ideally should come from Bitcoin PR bitcoin#26118, adding just this typedef is a minimal adaptation that doesn't affect correctness. Test FailureThe CI test failure in i2p_tests is unrelated to these changes and appears to be a flaky test (as noted by @PastaPastaPasta). Commit: d362ddf |

Summary
Backports Bitcoin Core PR bitcoin#27405 to Dash Core.
This PR improves time measurement in several areas by switching from
SystemClock(which can be affected by system time changes) toSteadyClock(monotonic clock) for duration measurements.Changes:

Backporting Notes
All timing-related code properly uses steady clock for duration measurements. The changes are type-safe improvements that prevent issues with system clock adjustments.
