Merge bitcoin/bitcoin#27405: util: Use steady clock instead of system clock to measure durations#386
Conversation
WalkthroughThe changes modernize time and duration handling across several modules by replacing raw integer-based millisecond timestamps with C++ chrono types and steady clocks. This refactoring affects network, wallet, and test code, updating variables, function signatures, and logic to use type-safe chrono durations and time points, and revising related tests and error expectations accordingly.

MAJOR SCOPE CREEP: InstantSend changes unrelated to Bitcoin steady clock backport.
These changes modify InstantSend database functionality - adding GUARDED_BY annotations and changing method parameter types from shared pointers to references and vice versa. However, this PR is supposed to backport Bitcoin Core commit e460c0a for steady clock duration measurements.
InstantSend is a Dash-specific feature that doesn't exist in Bitcoin Core at all. These changes represent major scope creep by bundling unrelated Dash-specific refactoring with the Bitcoin backport.
According to Dash backport guidelines, this violates the "No Scope Creep" rule and should be auto-rejected. Remove all InstantSend-related changes and focus exclusively on backporting Bitcoin's steady clock modifications plus minimal required Dash adaptations.

SCOPE CREEP: UniValue API modernization unrelated to steady clock backport.
These changes update UniValue method calls from the old API (get_int()) to newer templated methods (getInt<T>()) and replace global find_value() calls with member function calls. However, this PR is supposed to backport Bitcoin Core commit e460c0a for steady clock duration measurements, not modernize UniValue APIs.
While compilation fixes are sometimes necessary in Dash backports, these specific UniValue API changes appear to be a separate modernization effort rather than requirements for the steady clock functionality to compile.
Unless these UniValue API changes are specifically required for the steady clock backport to compile in Dash, they should be removed as scope creep. If they are compilation requirements, please provide justification explaining why the steady clock changes require these specific UniValue API updates.

🧹 Nitpick (assertive)
Return-by-value is fine; consider std::string_view for zero-copy literals
Changing the return type from const std::string to std::string removes an unnecessary top-level const, which is correct.
Given that RemovalReasonToString() returns string literals, returning std::string_view (or const char*) would avoid an allocation altogether and make the intent explicit. Not critical, but worth considering if this helper is on hot paths.
🤖 Prompt for AI Agents
In src/txmempool.h at line 359, the function RemovalReasonToString currently
returns a std::string by value, which causes unnecessary allocations for string
literals. Change the return type to std::string_view to enable zero-copy returns
of string literals, improving performance on hot paths. Update the function
signature accordingly and ensure the implementation returns string_view
references to the literals.
