Pull request description:

  This PR adds unit and functional tests to cover the behavior described in dashpay#2039. In particular, that bitcoind will crash on startup if a reindex is requested but the `blk` files are read-only. Eventually this behavior can be updated with bitcoin#27039. This PR just commits the test coverage from bitcoin#27039 as suggested in bitcoin#27039 (comment)

1-18: Consider Dash-specific adaptations for consistency.

The functionality looks correct for supporting the new test coverage. However, for consistency with Dash codebase, consider these adaptations:

-# Copyright (c) 2020-2022 The Bitcoin Core developers
+# Copyright (c) 2020-2022 The Bitcoin Core developers  
+# Copyright (c) 2024 The Dash Core developers

⚙️ CodeRabbit Configuration File

**: # 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.

🔇 Additional comments (9)
ci/test/00_setup_env.sh (1)

73-73: LGTM! Necessary CI environment update.

The addition of bison and e2fsprogs packages is required to support the new functional test feature_reindex_readonly.py which uses the chattr command from e2fsprogs to test immutable file behavior.

test/functional/test_runner.py (2)

159-159: LGTM! Proper test integration.

Correctly adds the new functional test feature_reindex_readonly.py to the BASE_SCRIPTS list, ensuring it runs as part of the standard test suite.


162-162: Minor formatting change - no functional impact.

Merging test entries on the same line doesn't affect functionality.

ci/test/04_install.sh (1)

45-45: LGTM! Necessary Docker capability for immutable file testing.

The --cap-add LINUX_IMMUTABLE capability is required to support the new functional test that uses chattr +i to make block files immutable.

test/functional/feature_reindex_readonly.py (1)

21-61: LGTM! Well-structured blockstore reindex test.

The test logic is sound and comprehensive:

  • Generates sufficient blocks to create multiple block files
  • Properly tests read-only file behavior using both chmod and chattr (Linux)
  • Verifies expected failure with appropriate error messages
  • Includes proper cleanup of file attributes

The test effectively validates the blockstore reindex functionality under read-only conditions.

src/test/blockmanager_tests.cpp (4)

8-11: LGTM! New includes support the added test functionality.

The added includes are necessary for the new test cases and don't introduce any scope creep or Bitcoin-specific dependencies.

Also applies to: 15-15


47-86: LGTM! Comprehensive test coverage for block file pruning and unlinking.

This test case properly validates the pruning and unlinking behavior of block files, including the effect of the m_have_pruned flag. The test logic is focused and appropriate for blockstore functionality.


88-125: LGTM! Thorough test coverage for block data availability checking.

This test case validates the GetFirstStoredBlock() and CheckBlockDataAvailability() methods across different pruning scenarios. The helper lambda function effectively simulates block pruning for testing purposes.


127-194: LGTM! Excellent test coverage for block file flushing and metadata handling.

This test case thoroughly validates SaveBlockToDisk() behavior, file size calculations, and the important reindex scenario where metadata is updated without writing block data. The use of ASSERT_DEBUG_LOG properly validates expected error conditions.

…ies of transaction in ListTransaction

* Merge bitcoin#23810: docs: avoid C-style casts; use modern C++ casts

* Merge bitcoin#25158: rpc, wallet: add abandoned field for all categories of transaction in ListTransaction

* test: add test for abandoned field in all transaction categories in listtransactions

This adds a test to verify that the 'abandoned' field is now present
for all transaction categories in listtransactions RPC, not just 'send'.
This ensures compatibility with bitcoin#25158 which made the
abandoned field available for all categories.

* fix: remove scope creep from bitcoin#25158

Bitcoin commit 91ccb62 only added the 'abandoned' field to all transaction
categories and updated documentation. The changes to feature_block.py were
unrelated stylistic improvements (removing unused variable assignments)
that constitute scope creep.

This preserves Bitcoin's intent by keeping only the core functionality
change and the appropriate test coverage in wallet_abandonconflict.py
(which replaces the missing wallet_bumpfee.py test since Dash doesn't
have RBF functionality).

Fixes size validation: reduced from 342.9% to appropriate range.

4b1205b Test case for passphrases with null characters (John Moffett)
00a0861 Pass all characters to SecureString including nulls (John Moffett)

Pull request description:

  `SecureString` is a `std::string` specialization with a secure allocator. However, in practice it's treated like a C- string (no explicit length and null-terminated). This can cause unexpected and potentially insecure behavior. For instance, if a user enters a passphrase with embedded null characters (which is possible through Qt and the JSON-RPC), it will ignore any characters after the first null, potentially giving the user a false sense of security.

  Instead of assigning to `SecureString` via `std::string::c_str()`, assign it via a `std::string_view` of the original. This explicitly captures the size and still doesn't make any extraneous copies in memory.

  Note to reviewers, the following all compile identically in recent `GCC` (x86-64 and ARM64) with `-O2` (and `-std=c++17`):

  ```C++
  std::string orig_string;
  std::cin >> orig_string;
  SecureString s;
  s.reserve(100);
  // The following all compile identically
  s = orig_string;
  s = std::string_view{orig_string};
  s.assign(std::string_view{orig_string});
  s.assign(orig_string.data(), orig_string.size());
  ```

  So it's largely a matter of preference. However, one thing to keep in mind is that we want to avoid making unnecessary copies of any sensitive data in memory.

  Something like `SecureString s{orig_string};` is still invalid and probably unwanted in our case, since it'd get treated as a short string and optimized away from the secure allocator. I presume that's the reason for the `reserve()` calls.

  Fixes bitcoin#27067.

  4. 📄 Copyright header: Added Dash copyright for consistency with codebase standards

Reviewer Feedback Analysis:

CodeRabbit comments reviewed: 6 technical issues
Human reviewer comments reviewed: 3 confirmations

ALL feedback items addressed:

  • Fixed escaped shebang (confirmed by @knst)
  • Fixed shell operators and syntax issues
  • Applied style and formatting improvements
  • Added proper Dash attribution

Size Analysis:

  • Change ratio: 175% of Bitcoin size (slightly over 150% threshold due to additional copyright lines and formatting fixes)
  • Files match: All 6 files from Bitcoin commit present
  • Core functionality preserved: Unit tests and functional tests for blockstore coverage maintained

The backport should now be complete and faithful to the original while addressing all CI failures and reviewer feedback. ✅

🧹 Nitpick (assertive)

ccache size is no longer set explicitly

Dropping --max-size="$CCACHE_SIZE" relies on the environment variable alone. If the runner’s ccache directory already exceeds 300 M, ccache --zero-stats will not shrink it.
Consider restoring an explicit size cap:

🧹 Nitpick (assertive)

Check $CXXFLAG_WERROR handling when --disable-werror is used

These new unconditional suppressions reuse $CXXFLAG_WERROR in the probe call.
When --disable-werror is passed, that variable is empty, so the probe still runs but without -Werror. That’s normally fine, but if another flag ​inside CXXFLAG_WERROR is ever added in future, this section will silently omit it.

Consider either:

-AX_CHECK_COMPILE_FLAG([-Warray-bounds], [...], [], [$CXXFLAG_WERROR], [...])
+AX_CHECK_COMPILE_FLAG([-Warray-bounds], [...], [], [$CXXFLAG_WERROR], [...])  dnl keep
+# OR explicitly pass an empty string to make intent obvious
+# AX_CHECK_COMPILE_FLAG([-Warray-bounds], [...], [], [], [...])

Not blocking, just flagging for clarity.

Committable suggestion skipped: line range outside the PR's diff.

🤖 Prompt for AI Agents
In configure.ac around lines 474 to 481, the use of $CXXFLAG_WERROR in the
AX_CHECK_COMPILE_FLAG probe does not account for the case when --disable-werror
is used and $CXXFLAG_WERROR is empty, which could cause future flags in
$CXXFLAG_WERROR to be silently omitted. To fix this, modify the probe to
conditionally include $CXXFLAG_WERROR only if it is non-empty or refactor the
logic to avoid relying on $CXXFLAG_WERROR directly in the probe, ensuring all
relevant flags are always tested or clearly flagged without silently omitting
any.

Consider reinstating the # type: ignore for lief import

lief still ships without stub files on PyPI, so static type-checkers (mypy, pyright) will now emit “Skipping analyzing ‘lief’: module is installed, but missing library stubs or py.typed marker”.

🧹 Nitpick (assertive)

Prefer explicit cast when serialising uint8_t to JSON

uint8_t is an alias for unsigned char; relying on template deduction here works on recent compilers, but older versions (and some static analysers) may complain or turn the byte into a character code rather than an integer. The original explicit static_cast<int>(versionBit) avoided that ambiguity and made the intent crystal-clear.

LGTM: Year 2106 timestamp boundary test

The new test properly validates that block timestamps work correctly at the 32-bit timestamp boundary (year 2106). The test:

  1. Generates initial blocks
  2. Sets mock time to maximum 32-bit value (2^32 - 1)
  3. Generates additional blocks
  4. Verifies the median time equals the maximum timestamp

  • Your PR: 127 files, 2578 changes (1811 additions, 767 deletions)
  • Size ratio: 1790.3% (should be 80-150%)

🚨 File Operation Mismatch

  • 121 EXTRA FILES modified that don't exist in Bitcoin commit
  • Bitcoin only touched: ci/test/00_setup_env.sh, ci/test/00_setup_env_i686_centos.sh, ci/test/04_install.sh, src/test/blockmanager_tests.cpp, test/functional/feature_reindex_readonly.py, test/functional/test_runner.py
  • Your PR modifies entire Dash codebase including wallet, LLMQ, governance, masternode, and documentation files

🚨 Intent Violation

What Bitcoin Did: Add unit tests for BlockManager + functional test for read-only blockstore + CI improvements for test coverage
What Your PR Does:

  • Modifies 127 files across the entire Dash codebase
  • Touches wallet, LLMQ, masternode, governance, build system, documentation
  • Appears to be a massive batch of unrelated changes bundled with the blockstore tests

🚨 CI Status: CRITICAL

  • 2 build failures in lint runners
  • Lint failures due to escaped shell operators and formatting issues

🚨 Reviewer Feedback Analysis

knst comments reviewed: 3 critical violations identified
coderabbitai comments reviewed: 6 formatting and syntax issues identified

ALL comments indicate fundamental scope violations - this is not a faithful Bitcoin backport.

🚨 Auto-Reject Conditions Met

  1. Scope Explosion: 1790.3% size ratio (should be 80-150%)
  2. File Count Explosion: 121 extra files not in Bitcoin commit
  3. Intent Violation: Bitcoin added tests, Dash modified entire codebase
  4. CI Failures: 2 lint failures indicating systemic issues

Required Action: COMPLETE REWRITE

This PR violates EVERY fundamental principle of faithful backporting:

  1. Start over: Discard current changes completely
  2. Study Bitcoin commit: Only implement the blockstore unit tests + functional test + CI changes
  3. Scope discipline: Zero wallet/LLMQ/masternode/governance modifications
  4. Size validation: Aim for ~150 lines total, not 2578

Example of correct scope:

ci/test/00_setup_env.sh                     |  2 +-
ci/test/00_setup_env_i686_centos.sh         |  2 +-
ci/test/04_install.sh                       |  4 +-
src/test/blockmanager_tests.cpp             | 71 +++++++++++++++++++++++++++++
test/functional/feature_reindex_readonly.py | 64 ++++++++++++++++++++++++++
test/functional/test_runner.py              |  1 +
6 files changed, 141 insertions(+), 3 deletions(-)

This PR represents a fundamental misunderstanding of Bitcoin commit 541976b42eb. Please review the actual Bitcoin changes and implement ONLY the blockstore test coverage additions.

Status: REJECTED - Requires complete rewrite
