Backports bitcoin#27405

Original commit: e460c0a

Backported from Bitcoin Core v0.26

This PR changes various time measurements from system clock to steady clock for more accurate duration measurements. The steady clock is not affected by system time adjustments and is better suited for measuring elapsed time.

Key changes:

  • Use steady clock in InterruptibleRecv for network timeouts
  • Use steady clock to throttle GUI notifications
  • Use steady clock to measure wallet scanning duration
  • Use steady clock to calculate wallet derive iterations
  • Replace IndexWaitSynced with steady clock timeout loops in tests

Note: Added MillisecondsDouble type definition to src/util/time.h as it was missing in Dash but required by the Bitcoin changes.

Summary by CodeRabbit

  • Refactor
    • Modernized time handling throughout the application by replacing raw integer timestamps and durations with type-safe C++ chrono types and steady clocks for improved precision and reliability.

Walkthrough

The 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.

Changes

File(s) Change Summary
Network timeout and SOCKS5 logic
src/netbase.cpp, src/test/fuzz/socks5.cpp
Refactored SOCKS5 receive timeout and related logic to use std::chrono::milliseconds instead of integer milliseconds; updated function signatures, global variable types, and related assignments.
Client model GUI update timing
src/qt/clientmodel.cpp
Replaced integer-based update notification timestamps with steady clock time points and chrono duration arithmetic for GUI update throttling.
Index synchronization tests
src/test/blockfilter_index_tests.cpp, src/test/txindex_tests.cpp
Replaced helper function calls for index synchronization with explicit polling loops using chrono-based timeouts and sleep intervals.
Time utilities
src/util/time.h
Added new type alias MillisecondsDouble as a double-precision chrono duration for milliseconds.
Wallet RPC scanning duration
src/wallet/rpc/wallet.cpp
Changed scanning duration conversion from integer division to chrono-based conversion using Ticks<std::chrono::seconds>.
Wallet passphrase timing logic
src/wallet/wallet.cpp
Updated passphrase timing logic to use steady clock and chrono durations for measuring and adjusting key derivation iterations.
Wallet scanning time tracking
src/wallet/wallet.h
Changed scanning start time and duration in CWallet from integer milliseconds to steady clock time points and chrono durations; updated related method signatures and assignments.
PSBT RPC test improvements

Files Analysis

This PR correctly implements Bitcoin's migration from GetTimeMillis() to steady clock for duration measurements in:

  • Network code (src/netbase.cpp) - InterruptibleRecv timing
  • GUI throttling (src/qt/clientmodel.cpp) - Notification rate limiting
  • Wallet operations (src/wallet/) - Passphrase derivation and scanning duration
  • Test infrastructure (src/test/) - Index synchronization timeouts

The addition of MillisecondsDouble in src/util/time.h is a necessary and minimal adaptation for the wallet timing calculations.

1-99: Critical: Unauthorized modifications to vendored univalue dependency detected.

Vendored libraries under src/univalue/ must remain untouched. This PR has directly removed the ParseInt32, ParseInt64, get_int(), and get_int64() routines from:

Please revert these changes. If you require API updates that match an upstream UniValue release, perform a proper vendor bump of the entire UniValue library instead of hand-editing individual files.

166-1120: Separate Dash-specific LLMQ RPC additions from the Bitcoin Core backport

Upon inspection, src/rpc/quorums.cpp:

  • Is not present in Bitcoin Core and thus wasn’t part of upstream PR bitcoin#27405 (steady‐clock).
  • Contains only Dash-specific LLMQ RPC commands—no steady‐clock, timing, or getInt<int>() modernizations were applied here.

To keep the backport focused on the intended upstream changes, please remove this file (and any related edits) from the current PR or relocate it into a standalone Dash feature PR.

src/bitcoin-cli.cpp (1)

548-557: Fix reversed condition and %s/argument type mismatch in peer-listing line

The ternary currently tests starts_with('v') == 0, which is true when the string does not start with 'v'.
As a result, the dashboard shows a blank transport-protocol version for valid v<n> strings and tries to print the second character when it shouldn’t.

Additionally, the %2s format specifier expects a C-string, but the ternary yields a single char, causing UB.

-    peer.transport_protocol_type.starts_with('v') == 0 ? peer.transport_protocol_type[1] : ' ',
+    (peer.transport_protocol_type.starts_with('v')      // valid “vN…”
+         ? peer.transport_protocol_type.substr(1)       // drop the leading ‘v’
+         : ""),

If you prefer to keep a single character, change the format specifier to %c accordingly.
Failing to address this will mis-report transport protocol versions and may crash with format-string sanitizers.

Verify this change was part of the original Bitcoin commit.

This change removes the ArgsManager::SENSITIVE flag from the -rpcbind argument registration, but it appears unrelated to the stated PR objective of switching to steady clock for time measurements. This could be scope creep that was inadvertently included.

Please verify that this exact change to remove ArgsManager::SENSITIVE from -rpcbind was actually part of Bitcoin Core commit e460c0a. If this change is not part of the original Bitcoin commit, it should be removed to maintain faithful backporting.

⚠️ Potential issue

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.

VALIDATION: FAIL

Scope Creep: DETECTED - InstantSend database refactoring, const qualifier removals in descriptors, and UniValue API modernization are all unrelated to the steady clock backport from Bitcoin Core commit e460c0a.

⚠️ Potential issue

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.

Also applies to: 235-236, 274-275, 506-506, 671-671, 680-680, 684-684, 714-714

In src/rpc/mining.cpp at line 123, revert the UniValue API usage from the newer
templated getInt<T>() method back to the original get_int() method and restore

to avoid scope creep since the UniValue API modernization is unrelated to the
steady clock backport. Only keep changes strictly required for the steady clock
functionality to compile, removing unrelated UniValue API updates.

Remove unintended TxToJSON verbosity changes

The added verbosity parameter (and its CHECK_NONFATAL guard) on TxToJSON isn’t present in Bitcoin Core commit e460c0a. Please revert these lines to keep this backport faithful. The upstream commit only focused on switching from system clock to steady clock; it did not introduce verbosity controls in src/rpc/rawtransaction.cpp. The UniValue get_int()getInt<int>() updates are fine and expected.

• src/rpc/rawtransaction.cpp:
– Line 69: revert signature back to
void TxToJSON(const CTransaction& tx, const uint256 hashBlock, const CTxMemPool& mempool, const CChainState& active_chainstate, const llmq::CChainLocksHandler& clhandler, const llmq::CInstantSendManager& isman, UniValue& entry)
– Remove the CHECK_NONFATAL(verbosity >= TxVerbosity::SHOW_DETAILS); at line 70 (and its associated verbosity parameter and default).

🤖 Prompt for AI Agents
In src/rpc/rawtransaction.cpp at line 69, revert the TxToJSON function signature
to remove the added verbosity parameter and its default value, restoring it to
the original signature without verbosity. Also, remove the
CHECK_NONFATAL(verbosity >= TxVerbosity::SHOW_DETAILS); line at line 70 and any
related code handling verbosity, ensuring the function matches the upstream
commit without verbosity controls.

⚠️ Potential issue

SCOPE CREEP: Remove const qualifier changes unrelated to steady clock backport.

These changes remove const qualifiers from DescriptorCache getter method return types, but this PR is supposed to be a backport of Bitcoin Core commit e460c0a which switches from system clock to steady clock for duration measurements. These descriptor cache changes are unrelated scope creep.

According to the Dash backport guidelines, only Bitcoin's intended changes plus minimal Dash adaptations are allowed. Const qualifier removals in descriptor code have nothing to do with steady clock timing improvements.

Remove these unrelated changes and focus only on the steady clock modifications from the original Bitcoin commit.

🤖 Prompt for AI Agents
In src/script/descriptor.h around lines 69 to 73, the getter methods of
DescriptorCache have had their const qualifiers removed, which is unrelated to
the steady clock backport. Revert these methods to include the const qualifiers
on their return types as originally defined, removing any changes that drop
const. This will keep the scope focused solely on the steady clock timing
improvements without unrelated descriptor code modifications.

🧹 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.

⚠️ Potential issue

Unauthorized modification to vendored dependency should be removed.

According to the coding guidelines, vendored dependencies in src/univalue/ should not be modified under any circumstances during Bitcoin Core backports. These include header changes are unrelated to the PR's stated objective of switching from system clock to steady clock for duration measurements and appear to be scope creep.

This modification should be removed to maintain the integrity of the vendored UniValue library.

🤖 Prompt for AI Agents
In src/univalue/lib/univalue_write.cpp lines 5 to 10, the inclusion of headers
or any other changes to vendored UniValue library files should be reverted.
Remove any modifications to these vendored dependency files to comply with
coding guidelines and keep the backport focused on switching from system clock
to steady clock without altering unrelated code.

⚠️ Potential issue

Modification inside vendored univalue subtree violates repository policy

Per the coding-guideline rule:

src/{crc32c,dashbls,gsl,immer,leveldb,minisketch,secp256k1,univalue}/** : Do not make changes under any circumstances to vendored dependencies

src/univalue/... is treated as a vendored third-party library. Even seemingly harmless header tweaks are disallowed because they break the “untouched upstream” guarantee and complicate future upgrades.

Please revert the change or, if genuinely required, move the test out of the vendored path and update build scripts accordingly.

🤖 Prompt for AI Agents
In src/univalue/test/test_json.cpp around lines 7 to 11, the modification
violates the repository policy forbidding changes inside the vendored univalue
subtree. To fix this, revert all changes made in this file or move the test code
outside the src/univalue directory to a non-vendored location, then update the
build scripts to include the new test location accordingly.

Verify scope: const qualifier removal unrelated to steady clock migration.

This change removes the const qualifier from the return type, but doesn't appear related to the steady clock migration described in the PR objectives. Please verify this change is part of the intended Bitcoin commit e460c0a.

Remove unrelated const qualifier and UniValue API changes

The const removals in return types and the UniValue API update are not part of Bitcoin commit e460c0a (steady clock migration) and appear to be unintended scope creep. Please revert these changes or move them to a separate PR:

  • src/util/system.cpp:271
    • Reverted from const std::set<std::string> back to preserve original qualifier.
  • src/util/system.cpp:291
    • Revert std::list<SectionInfo> back to const std::list<SectionInfo>.
  • src/util/system.cpp:629
    • Restore value.get_int64() instead of value.getInt<int64_t>().

Verification: Grepped commit e460c0a for GetUnsuitableSectionOnlyArgs and found no matching changes in that upstream diff.

🤖 Prompt for AI Agents
In src/util/system.cpp at line 271, the return type of
ArgsManager::GetUnsuitableSectionOnlyArgs() was changed by removing the const
qualifier, which is unrelated to the intended commit. Revert the return type
back to const std::set<std::string> to preserve the original qualifier.
Similarly, at lines 291 and 629, revert the changes to const
std::list<SectionInfo> and restore value.get_int64() respectively. These changes
should be isolated or removed to avoid unintended scope creep.

❌ Backport Verification - CATASTROPHIC FAILURE

Original Bitcoin commit: e460c0a24a
Reviewed commit hash: -verify-

Critical violations detected - this PR cannot be salvaged and must be recreated:

🚨 Size Explosion (Auto-Reject Trigger)

  • Bitcoin commit: 8 files changed, 70 total changes
  • Dash PR: 138 files changed, 3,291 total changes
  • Size ratio: 4,701.4% (exceeds 500% limit by 940x)

🔍 Root Cause Analysis

This appears to be a dependency explosion where a simple time utility change has triggered massive scope creep across the entire Dash codebase. The Bitcoin commit bitcoin#27405 "Use steady clock instead of system clock to measure durations" was a surgical 8-file change, but this PR has ballooned to include:

  • Complete univalue library changes (25+ files)
  • Entire Dash-specific subsystems (governance, instantsend, llmq, coinjoin)
  • Build system modifications (Makefile.am, configure.ac)
  • Test infrastructure changes (lint scripts, functional tests)
  • Unrelated RPC modifications

❌ Why This Cannot Be Fixed

  1. Fundamental Architecture Mismatch: The change appears to have been applied as a global search-replace across unrelated Dash components
  2. Infrastructure Import: Importing entire Bitcoin subsystems rather than targeted adaptation
  3. Scope Violation: 94x larger than acceptable threshold indicates complete loss of Bitcoin commit intent

📋 Proper Implementation Approach

A correct backport should:

  1. Identify the core change: Replace system time with steady time in specific time measurement contexts
  2. Target only affected files: Focus on src/util/time.h, src/netbase.cpp, wallet timing, and test files that actually measure durations
  3. Preserve Bitcoin scope: ~8-12 files maximum, <200 total changes
  4. Avoid global replacements: Don't modify unrelated Dash-specific components
