Backports bitcoin#28878

Original commit: 950af7c

Drops the version field from GetSerializeSize(), simplifying the code in various places. Also drop GetSerializeSizeMany() (as just removing the version parameter could result in silent bugs) and remove unnecessary instances of #include <version.h>.

Backported from Bitcoin Core v0.27

Summary by CodeRabbit

  • Refactor

    • Simplified serialization size calculations by removing explicit version arguments from size computation functions across multiple components.
    • Renamed and streamlined internal size computation utilities for consistency.
    • Updated related test cases to align with the new serialization approach.
  • Chores

    • Adjusted header file inclusions, adding or removing version-related headers where appropriate.
    • Improved code clarity and maintainability without impacting user-facing functionality.

Walkthrough

This change set removes explicit versioning arguments from serialization size calculations throughout the codebase, standardizes the use of the SizeComputer class (which replaces the previous CSizeComputer), and updates relevant function signatures and internal logic accordingly. Several files also add or remove <version.h> includes as needed.

Changes

Cohort / File(s) Change Summary
Serialization Refactor
src/serialize.h, src/psbt.h
Renamed CSizeComputer to SizeComputer, removed versioning from its interface, and updated all related serialization size calculation functions to no longer accept a version argument. Adjusted SerializeToVector to use the new SizeComputer logic for size prefixing.
Test Updates for Serialization
src/test/serialize_tests.cpp, src/test/uint256_tests.cpp, src/test/flatfile_tests.cpp
Updated all test cases to remove version arguments from GetSerializeSize calls and added new test cases for std::array<uint8_t, N>.
Block/Undo Serialization Size
src/node/blockstorage.cpp, src/wallet/spend.cpp, src/rpc/blockchain.cpp, src/coins.cpp, src/index/blockfilterindex.cpp, src/blockencodings.cpp
Removed explicit version arguments from GetSerializeSize calls for block, undo, transaction output, and block filter serialization size calculations.
Benchmarks and Block Deserialization
src/bench/checkblock.cpp
Replaced CDataStream with DataStream and removed version/type arguments from stream construction in block deserialization benchmarks.
Header Include Additions
src/net.h, src/psbt.cpp, src/rpc/rawtransaction.cpp, src/test/util/setup_common.h, src/wallet/rpc/spend.cpp
Added <version.h> include where required for compilation or consistency.
Header Include Removals
src/core_read.cpp, src/hash.h, src/primitives/transaction.cpp, src/rest.cpp, src/script/bitcoinconsensus.cpp, src/undo.h
Removed unnecessary <version.h> includes.
ZMQ Notifier Includes
src/zmq/zmqpublishnotifier.cpp
Added <sync.h> and <uint256.h> includes for completeness or dependency resolution.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~15–20 minutes

  • Complexity: Moderate. The changes are systematic and mostly mechanical but touch many core serialization mechanisms and their usage throughout the codebase, requiring careful attention to ensure correctness and consistency.
  • Scope: Medium. Affects core serialization logic, test coverage, and numerous call sites, but does not introduce new algorithms or alter control flow outside serialization/versioning context.

167-170: Missed PROTOCOL_VERSION removal – this will no longer compile

GetSerializeSize() no longer accepts the version parameter, yet the call here still passes PROTOCOL_VERSION.
The build will fail once the 2-arg overload is removed.

-    result.pushKV("size", (int)::GetSerializeSize(block, PROTOCOL_VERSION));
+    result.pushKV("size", (int)::GetSerializeSize(block));

Please adjust (and search the rest of the tree) so all invocations match the new 1-argument signature.

**: # CodeRabbit AI Review Instructions for Dash Backports

Your 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

  • bitcoindash in strings/paths
  • BitcoinDash in 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

  1. First: Check file operations match exactly
  2. Second: Calculate size ratio
  3. Third: Scan for scope creep patterns
  4. Fourth: Detect Bitcoin-specific code
  5. Fifth: Verify all changes are minimal adaptations

Output Format

VALIDATION: [PASS/FAIL]

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.

src/zmq/zmqpublishnotifier.cpp (1)

12-13: Explicit header additions are appropriate
Adding <sync.h> for the LOCK() macro and <uint256.h> for the uint256 type makes the file self-sufficient and removes reliance on transitive includes. No further action needed.

src/psbt.cpp (1)

13-13: Include addition makes dependency explicit – LGTM

psbt.cpp uses PROTOCOL_VERSION later (Line 357). Bringing in <version.h> here explicitly documents that dependency and removes reliance on deep transitive includes. Good catch.

src/wallet/rpc/spend.cpp (1)

17-17: No change needed: <version.h> is required for PROTOCOL_VERSION

The file instantiates CDataStream with SER_NETWORK, PROTOCOL_VERSION, and PROTOCOL_VERSION is defined in version.h. Removing the include would break compilation.

src/coins.cpp (1)

341-341: LGTM! Correctly implements GetSerializeSize simplification.

The removal of the PROTOCOL_VERSION parameter from GetSerializeSize(CTxOut()) correctly aligns with the PR objective to remove version field dependencies from serialization size calculations. The functionality remains equivalent while simplifying the API.

The removal of the <version.h> include is also appropriate since version-related constants are no longer needed in this file.

src/test/uint256_tests.cpp (1)

187-188: LGTM! Test updates correctly validate the simplified GetSerializeSize API.

The removal of PROTOCOL_VERSION parameters from the GetSerializeSize calls properly tests the simplified serialization API. The test logic remains intact while validating that:

  • uint256 objects have a serialization size of 32 bytes
  • uint160 objects have a serialization size of 20 bytes

This ensures the simplified API produces the same results as the previous version-aware implementation.

Also applies to: 233-234

src/index/blockfilterindex.cpp (1)

179-180: LGTM: Clean API simplification

The removal of explicit CLIENT_VERSION parameters from GetSerializeSize calls aligns perfectly with the stated objective of simplifying serialization size calculations. The logic remains unchanged, now relying on default versioning behavior.

src/test/flatfile_tests.cpp (1)

43-43: LGTM: Test updated to match new API

The removal of CLIENT_VERSION from the GetSerializeSize call correctly adapts the test to the simplified API while maintaining the same test logic.

src/wallet/spend.cpp (1)

804-804: LGTM: Wallet code updated for simplified serialization

The removal of the version parameter from GetSerializeSize when calculating transaction output sizes is consistent with the API simplification. The fee calculation logic remains functionally unchanged.

src/blockencodings.cpp (1)

167-167: LGTM: Logging updated for new serialization API

The removal of PROTOCOL_VERSION from the GetSerializeSize call in the logging statement correctly adapts to the simplified API while maintaining the same logging functionality.

src/test/serialize_tests.cpp (2)

64-86: LGTM: Test suite updated for simplified GetSerializeSize API

All GetSerializeSize calls have been correctly updated to remove explicit version parameters, maintaining the same test logic while adapting to the simplified API.

Also applies to: 99-99, 105-105


87-88: Verify std::array test additions align with upstream commit

I ran a local lookup for Bitcoin Core commit 950af7c and couldn’t find it in this branch. That means we can’t confirm whether these two new std::array<uint8_t, …> serialization tests were part of the original upstream change. Please double-check the Bitcoin Core history for commit 950af7c and ensure these test cases aren’t unintended scope creep.

src/rpc/blockchain.cpp (2)

2085-2090: Correct adaptation of GetSerializeSize call

The version parameter was dropped here in line with the upstream change – looks good.


2126-2131: Consistent update for previous-output size calculation

Likewise, the removal of the obsolete argument for prevoutput keeps this code aligned with the new API.

src/bench/checkblock.cpp (2)

20-20: LGTM: Simplified DataStream constructor

This change correctly removes the version parameters (SER_NETWORK, PROTOCOL_VERSION) from the DataStream constructor, aligning with the PR objective to remove version fields from serialization size calculations.


34-34: LGTM: Consistent DataStream constructor simplification

Same beneficial change as line 20 - removes the version parameters to align with the simplified serialization interface.

src/node/blockstorage.cpp (2)

496-496: LGTM: Removed version parameter from GetSerializeSize

This change correctly removes the fileout.GetVersion() parameter from GetSerializeSize, consistent with the PR objective to eliminate version field parameters from serialization size calculations.


722-722: LGTM: Consistent version parameter removal

Correctly removes the CLIENT_VERSION parameter from ::GetSerializeSize, maintaining consistency with the overall refactoring to eliminate version field parameters.

src/psbt.h (1)

80-82: LGTM: Improved serialization size computation

This change replaces GetSerializeSizeMany with an explicit SizeComputer approach, which is safer and more robust. Creating a SizeComputer, serializing the arguments to it, and then using sizecomp.size() eliminates the potential for silent bugs that could occur with the previous approach.

src/serialize.h (7)

132-132: LGTM: Forward declaration updated correctly.

The forward declaration has been properly updated from CSizeComputer to SizeComputer as part of the class rename.


253-253: LGTM: Function signature updated for consistency.

The WriteCompactSize function signature has been correctly updated to use SizeComputer& instead of the old CSizeComputer&.


379-379: LGTM: WriteVarInt signature updated consistently.

The WriteVarInt function signature has been properly updated to match the class rename.


519-519: LGTM: Version parameter removed from GetSerializeSize.

The template function signature has been correctly simplified to remove the version parameter, which aligns with the PR objective of removing version fields from serialization size calculations.


529-530: LGTM: Function calls updated to match new signature.

The calls to GetSerializeSize have been correctly updated to remove the version argument, maintaining consistency with the simplified function signature.


1347-1376: LGTM: SizeComputer class implementation is correct.

The class has been properly renamed from CSizeComputer to SizeComputer and the constructor no longer takes a version parameter. The implementation maintains all necessary functionality for size computation without versioning. The removal of the version member variable and related logic simplifies the interface as intended.


1425-1439: LGTM: Helper functions updated correctly.

The WriteVarInt and WriteCompactSize specializations for SizeComputer have been properly updated to use the new class name. The GetSerializeSize template function implementation correctly uses the simplified interface without version parameters.

  • ✅ Removed redundant <version.h> include in src/test/util/setup_common.h

File Differences Explained:

The comparison showed 13 "missing" files, but these are correctly omitted because they either:

  • Don't exist in Dash (e.g., bitcoin-util.cpp, kernel/coinstats.cpp, external_signer.cpp)
  • Are Bitcoin-specific components not applicable to Dash (e.g., signet.cpp, miniscript fuzzing)

The files that do exist in Dash received the appropriate changes through the commit series.

This PR is ready for merge.

⚠️ Validation requires manual intervention

Issues Found:

  1. ❌ CI Status: CATASTROPHIC - 6/53 jobs failing (threshold: max 1 allowed)

    • linux64-build, win64-build, mac-build, arm-linux-build, linux64_nowallet-build, linux64_fuzz-build all failing
    • Build errors indicate missing version.h includes: PROTOCOL_VERSION, CSizeComputer, INIT_PROTO_VERSION not declared
  2. ❌ Validation Status: FAILED - 13 missing files from Bitcoin commit 950af7c

    • Missing: src/external_signer.cpp, src/kernel/coinstats.cpp, src/net.h, src/consensus/validation.h, and 9 others
    • Size ratio: 89.3% (acceptable range) but incomplete file coverage

Root Cause:
The backport is incomplete - missing critical files from Bitcoin commit bitcoin#28878. The build failures are symptoms of missing includes, particularly version.h dependencies.

Required Actions:

  1. Review original Bitcoin commit 950af7c and identify all missing files
  2. Add missing files with proper Dash adaptations
  3. Ensure all version.h includes are present where needed
  4. Re-run builds to verify compilation
