3fcd7fc Do not use std::vector = {} to release memory (Pieter Wuille) Pull request description: It appears that invoking `v = {};` for an `std::vector<...> v` is equivalent to `v.clear()`, which does not release its allocated memory. There are a number of places in the codebase where it appears to be used for that purpose however (mostly written by me). Replace those with `std::vector<...>{}.swap(v);` (using a helper function `ClearShrink` in util/vector.h). To explain what is going on: `v = {...};` is equivalent in general to `v.operator=({...});`. For many types, the `{}` is converted to the type of `v`, and then assigned to `v` - which for `std::vector` would ordinarily have the effect of clearing its memory (constructing a new empty vector, and then move-assigning it to `v`). However, since `std::vector<T>` has an `operator=(std::initializer_list<T>)` defined, it has precedence (since no implicit conversion is needed), and with an empty list, that is equivalent to `clear()`. I did consider using `v = std::vector<T>{};` as replacement for `v = {};` instances where memory releasing is desired, but it appears that it does not actually work universally either. `V{}.swap(v);` does.

WalkthroughThis update introduces a broad set of changes across the codebase, including new features, refactorings, bug fixes, test enhancements, and documentation updates. Notable changes include the addition of new REST API query parameter handling, improvements to wallet loading benchmarks, updates to hex parsing logic, enhancements to mempool and pruning logic, new and updated functional and fuzz tests, and several refactorings for clarity, thread safety, and error handling. Multiple files now use more modern C++ time APIs, and several test and build scripts were updated for improved reliability and maintainability. Changes

4bbf5dd Detailed error message for passphrases with null chars (John Moffett) b4bdabc doc: Release notes for 27068 (John Moffett) 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.

174-1278: Remove unrelated Python test cleanup from this backportThe C++ vector‐memory management changes from Bitcoin bitcoin#28452 (ClearShrink implementation in
src/util/vector.hand its usage insrc/net.cpp, plus corresponding tests intest/util_tests.cpp) are present in this branch. The modifications intest/functional/feature_block.py—removing unused assignments fromnext_block()calls—do not pertain to “Do not use std::vector = {} to release memory” and constitute scope creep.Please revert or isolate the changes in:
- test/functional/feature_block.py (the cleanup of unused
next_block()assignments)src/test/httpserver_tests.cpp (1)
1-39: VALIDATION: FAIL - Severe scope creep violationThis entire new test file for HTTP server query parameter functionality is completely unrelated to the stated PR objective of backporting Bitcoin Core commit 28452 about
std::vector = {}memory management and adding a missing test case forClearShrink.The file tests
GetQueryParameterFromUrifunction and HTTP request URI handling, which has nothing to do with vector memory management or theClearShrinkfunction.This entire file should be removed from this backport PR as it represents massive scope creep - adding completely unrelated HTTP server functionality testing.
src/rpc/blockchain.cpp (1)
1089-2678: VALIDATION: FAILFile Operations: MISMATCH - Bitcoin Core commit bitcoin#28452 modified 4 files with 71 total changes, but this Dash PR only modifies 1 file with ~5 lines changed.
Size Ratio: 7% (Bitcoin: 71 lines, Dash: ~5 lines) - Far below the required 80-150% range.
Scope Creep: DETECTED - The actual changes (pruneblockchain semantics, dumptxoutset error handling) don't match the PR title "Do not use std::vector = {} to release memory" or the stated objective of adding ClearShrink test cases.
Bitcoin-Specific Code: NONE
Completeness: MISSING FILES - Missing 3 out of 4 files from the original Bitcoin commit. According to PR objectives, the core ClearShrink functionality already exists in Dash.
Fix Instructions:
- This appears to be a different Bitcoin commit than bitcoin#28452 being backported
- Close this PR since the stated Bitcoin bitcoin#28452 functionality is already implemented in Dash per the PR objectives
- If these changes are needed, create a separate PR with correct title/description identifying the actual Bitcoin commit being backported
- For future backports, ensure all relevant files are included or clearly document why certain changes are not applicable
Verification needed: Confirm which Bitcoin commit these changes actually originate from.

- Modifies vector handling across 4 files with 71 total changes
Instead, the shown changes include hex parsing, SQLite synchronization, HTTP query parameters, and time API updates - none of which are part of Bitcoin bitcoin#28452.
Per the PR objectives, the actual backport contains only a single blank line addition, representing ~1.4% of the original Bitcoin changes. The reviewer already identified that the ClearShrink functionality exists in Dash and recommended closing this PR.

1-1010: Update PR Objectives: Incorrect Backport of REST API ChangesThe modifications in
src/rest.cpp(and accompanyingrest_tests.cpp) clearly correspond to the Bitcoin Core changes that introduced theRESTResponseFormatenum,ParseDataFormatlogic (query‐string stripping), and newcount=query parameter support on REST endpoints—not the memory‐management fix (std::vector = {}avoidance) orClearShrinktests claimed in commit 8ef6729.Please address the following:
- Confirm which Bitcoin Core commit these REST API enhancements originate from (they are unrelated to vector memory management).
- Update the PR title/description to reference the correct commit hash and intended scope.
- If the goal remains the memory‐management backport, remove or relocate these REST API changes to a separate PR.

Bitcoin-Specific Code: NONE
Completeness: SEVERELY INCOMPLETE - Missing all relevant files from Bitcoin commitCritical Issue: This file implements wallet loading benchmarks, but the Bitcoin commit 8ef6729 is about "Do not use std::vector = {} to release memory" and the ClearShrink function. These are completely unrelated changes.
According to the PR objectives:
- The Bitcoin commit modifies 4 files with 71 changes
- The changes involve vector memory management and ClearShrink testing
- This PR only adds 1 unrelated file
Fix Instructions:
- Remove this wallet loading benchmark file - it's not part of the Bitcoin commit
- The PR objectives already indicate that ClearShrink functionality exists in Dash
- Either properly backport all relevant changes from Bitcoin commit 8ef6729 or close this PR as the functionality is already implemented
src/validation.cpp (1)
1-5986: Summary: Wrong changes for the stated PR objectiveAfter reviewing all changes in this file:
- Sequence lock refactoring: New functions for calculating lock points, API changes to separate calculation from validation
- Chain tip API change: SetTip now uses references instead of pointers
- BIP30 exception handling: Special case handling for historical blocks with duplicate coinbases
- Integration updates: Mempool and reorg handling updated to use new APIs
None of these changes relate to the stated PR objective of backporting Bitcoin Core commit 8ef6729 about avoiding
std::vector = {}for memory release.This appears to be either:
- The wrong file included in the PR
- The wrong PR description
- A different Bitcoin Core commit being backported
The PR should be updated to either:
- Include the correct files that address vector memory management
- Update the description to match what's actually being backported
- Remove these unrelated changes

Pinning lief==0.13.1 may break reproducibility on future CI images
lief often publishes manylinux wheels only for a subset of Python versions and glibc combos.
Consider:
- Adding a comment why 0.13.1 is chosen (latest with wheels?).
- Falling back to
--no-binary :all:compile path if wheels disappear. - Caching the wheel in
contrib/cilike other toolchain pins.
This prevents sudden CI breakage when upstream yanks/relocates binaries.

Ensure reproducible LIEF installation in CI
File: ci/lint/04_install.sh (around line 38)
The current line pins LIEF to 0.13.1 but provides no rationale, no build-from-source fallback, and no cached wheel if PyPI wheels vanish. To avoid future CI failures, please:
- Add a comment explaining why
lief==0.13.1is chosen (e.g. last version with manylinux wheels for our Python/glibc matrix). - Try installing from source if the wheel is removed, e.g.:
${CI_RETRY_EXE} pip3 install lief==0.13.1 || \ ${CI_RETRY_EXE} pip3 install --no-binary :all: lief==0.13.1
- Vendor or cache the wheel under a new
contrib/ci/directory (as with other toolchain pins) and prefer it before falling back to PyPI.
These steps will guard against upstream wheel removals and keep CI builds stable.

pinned wheel from PyPI, and if that fails, retry installing from source using
the --no-binary option. Additionally, set up caching or vendoring of the lief
wheel under contrib/ci/ and update the script to prefer installing from this
local cache before falling back to PyPI to ensure CI stability.

Renamed variable needs follow-up clean-up
CCACHE_MAXSIZE replaces CCACHE_SIZE, but the rest of the CI scripts (e.g. build helpers or
GitHub-Actions workflow steps) may still export or reference the old name. A quick repo-wide check
avoids silent regressions where the limit reverts to the ccache default.

nproc still executed on host – command substitution happens before CI_EXEC
CI_EXEC echo "Number of CPUs (nproc): $(nproc)" expands $(nproc) before entering the container, so the printed value is from the host, not the CI container. Wrap it in a second shell inside the container:
-CI_EXEC echo "Number of CPUs (nproc): $(nproc)"
+CI_EXEC bash -c 'echo "Number of CPUs (nproc): $(nproc)"'This ensures the nproc binary runs in the same namespace as the rest of the build.

In ci/test/04_install.sh around lines 99 to 101, the command substitution
$(nproc) is executed on the host before being passed to CI_EXEC, causing the CPU
count to reflect the host instead of the container. To fix this, wrap the
command substitution in a shell inside the container by changing the line to
execute a shell that runs nproc, ensuring nproc runs in the container's
namespace and returns the correct CPU count.

🧹 Nitpick (assertive)
Proper import restructuring with minor linter issue

Proper API adaptation with assert usage note
The function calls correctly adapt to the internal byte_to_base58 API, maintaining the same functionality while eliminating external dependencies.
Note: Static analysis flags the assert statement (line 83). Consider whether this should be a proper validation with exception handling for production use, or if it's acceptable for a test generation script.

Potential scope creep - RPC error handling improvements unrelated to stated objective.
The addition of error handling tests for invalid file paths in dumptxoutset RPC appears unrelated to the stated PR objective of backporting Bitcoin commit bitcoin#28452 about vector memory management (std::vector = {} and ClearShrink function).
This looks like scope creep where RPC error handling improvements have been included alongside the main backport.

VALIDATION: FAIL - Scope creep violation
This new test case for wallet PSBT funding validation is unrelated to the stated PR objective of backporting Bitcoin Core commit 28452 about std::vector = {} memory management and adding a missing test case for ClearShrink.
The test verifies RPC error handling for zero-value transactions, which has nothing to do with vector memory management or the ClearShrink function.
This change should be removed from this backport PR as it represents scope creep beyond the intended Bitcoin commit scope.

Improved error handling with explicit exception.
Replacing the assertion with an explicit ValueError provides better error handling and clearer failure messages compared to silent assertion failures.
However, this base58 encoding refactoring appears unrelated to the stated PR objective of backporting Bitcoin commit bitcoin#28452 about vector memory management (std::vector = {} and ClearShrink function). This may represent scope creep.
