ci: verify cross-build SDK archives

This change adds checksum verification to the build system's downloads of Apple, FreeBSD, NetBSD, and OpenBSD software development kits (SDKs). Before this patch, those SDK archives were downloaded at build time and extracted without confi…

This is a routine maintenance update to Bitcoin Core's continuous integration (CI) system. It changes the version number of the NetBSD operating system used for cross-compilation testing from a release candidate (11.0_RC6) to the final rel…

test: require `TryGetTotalRam()` detection

This commit only changes a test file and build configuration. It removes the option to skip a test when the system cannot detect total RAM, and instead requires the RAM detection to succeed. It does not change any production wallet, networ…

common: cache total RAM as `uint64_t`

This is a small code-quality change in Bitcoin Core that changes how the program remembers how much RAM a computer has. It now stores the RAM amount as a 64-bit unsigned integer and caches the value once, instead of repeatedly detecting it…

Integer type widened from size_t to uint64_t to avoid clampingRemoved explicit clamp to std::numeric_limits<size_t>::max()Value is now cached once to prevent TOCTOU-style inconsistency between cache selection and warning logic

This commit is a small code cleanup: it moves two constants that define the minimum and maximum size of the database cache (dbcache) into a shared kernel header so that both the node and kernel code use the same limits. There is no change …

kernel: allow setting chainstate `dbcache`

This commit adds a new public API knob to the Bitcoin Core 'libbitcoinkernel' library so that programs using the kernel can choose how much memory to use for the chainstate database cache. It also enforces minimum and maximum size limits. …

scripted-diff: use `MIN_DBCACHE_BYTES`

This commit is a simple automated rename of a constant from MIN_DB_CACHE to MIN_DBCACHE_BYTES across five files. The value stays the same (4 MiB), and no behavior changes. It is a code-cleanup/refactoring change with no security relevance.

coins: group private cache helpers

This commit is a pure code cleanup: it moves two internal helper functions (FetchCoin and ReallocateCache) into the existing private section of a C++ class. There are no functional changes, no bug fixes, and no security implications.
