fuzz: clang-format LIMITED_WHILE

This commit is purely a code-style cleanup. It adds a space between the macro name LIMITED_WHILE and its opening parenthesis across many fuzz test files, plus a few tiny formatting fixes like removing a redundant semicolon and fixing inden…

refactor: Use u64 over size_t for all cache sizes to fix a 32-bit overflow

This commit fixes a bug in Bitcoin Core that only affects 32-bit computers. When the program calculated how much database cache to allocate, it multiplied a large default cache value by 10. On 32-bit systems that multiplication overflowed,…

Integer overflow in cache-size calculation on 32-bit systemsUnsigned multiplication overflow explicitly mentioned in commit message with runtime sanitizer outputType promotion from size_t to uint64_t to prevent platform-dependent width issues

rpc: Run type check on decodepsbt result

This is a code-quality fix for Bitcoin Core's RPC help output. It changes how the documentation generator marks parts of the response as '...' (elided) so that the internal type checker can still verify the real data types. It does not cha…

test: Move event loop creation to network thread

This is a small test-only change in Bitcoin Core's Python testing framework. It moves where an internal networking event loop is created so it is created on the same thread that later runs it, rather than on the main test thread. The goal …

test: Set assert_debug_log timeout to 0

This commit only changes Bitcoin Core's internal functional test code. It makes the default timeout for a debug-log assertion helper stricter (0 seconds instead of 2 seconds) and updates existing tests to explicitly pass a 2-second timeout…

refactor: Enforce readability-avoid-const-params-in-decls

This commit is a pure code-style cleanup. It removes unnecessary 'const' keywords from function parameter declarations in header files across the Bitcoin Core codebase and adds a clang-tidy rule to prevent them from being reintroduced. The…

This commit is a cleanup change to Bitcoin Core's internal benchmark test code. It removes an unused 'priority level' argument from the BENCHMARK macro and from all benchmark definitions. The change does not affect the live Bitcoin network…

scripted-diff: Bump copyright headers after encoding changes

This commit only updates copyright years in file headers from a fixed range (for example '2018-2022') to 'year-present'. It makes no changes to program logic, network behavior, or security-sensitive code. There is no security relevance.

contrib: Remove confusing and redundant encoding from IO

This commit removes explicit 'UTF-8' encoding declarations from dozens of helper and test scripts in the Bitcoin Core repository. In Python 3, removing the encoding argument makes file operations fall back to the system's default locale en…

refactor: Return uint64_t from GetSerializeSize

This is a small defensive code change in Bitcoin Core that changes an internal size-measuring helper from using the system's native size type (size_t) to always using a 64-bit unsigned integer (uint64_t). On 64-bit computers nothing effect…

refactor: Use uint64_t over size_t for serialized-size values

This is a code cleanup change that swaps the variable type `size_t` for `uint64_t` in a handful of places that store serialized data sizes. On 64-bit computers the two types are the same size, so nothing changes. On 32-bit computers, `uint…
