dev branched from the release line before 1c3523aac and so lost -Wa,-mbig-obj
from util/build-win.sh. Without it the Windows cross-compile fails at link: large
template/boost-heavy translation units exceed the PE/COFF ~32k-section limit, and
GNU ld emits "dangerous relocation" on .pdata and crashes. v1.1.0 therefore could
not produce a win64 binary at all.
The merge brings only that one file back. util/build-win.sh is the only file both
sides touched, and the two edits are ~20 lines apart, so it auto-merges keeping
both fixes: -Wa,-mbig-obj on the configure line and -DARCH=default on the cmake
line. Verified after merging that dev's own work is intact -- the extended
checkpoint table, the guarded RandomX dedup, the 1.1.0 version bump, and
ARCH=default in the other two build scripts.
No C++ changed; the only delta from the pre-merge dev is the shell script.

The RandomX skip in RandomXValidationRequired() has never fired in production.
It skips verification below the last in-index checkpoint, but the DRAGONX
checkpoint table ended at 2,838,000 while ASSETCHAINS_RANDOMX_VALIDATION is
2,838,976 -- the window was empty by 976 blocks. Every block since the RandomX
activation has been fully verified, at ~65ms per hash on the fastest x86 core
available and ~180ms on a typical user machine.
Extends the table by 388 entries at stride 1000, from 2,839,000 to 3,226,000
(tip - ~5,600, far beyond any reorg this chain has produced; max observed depth
is 3-4). Blocks requiring a RandomX verify drop from 391,447 to ~5,500. The
same extension carries the existing script/zk-proof skip (fScriptChecks,
fExpensiveChecks) over the same range.
Checkpoint data verification, before it went anywhere near source:
- generated on a continuously-synced node
- all 388 hashes identical on 4 other full nodes (388/388 on each)
- reverse-verified hash -> height, all on the active chain
- re-extracted from the patched file and diffed against the verified set
- 2,838 pre-existing entries unchanged; all 3,226 ascending and unique
Trailer fields computed from RPC, not util/checkpoints.pl, which greps a
rotating debug.log and assumes 1440 blk/day (DragonX is 2400).
Also switches all three build scripts from -DARCH=native to -DARCH=default.
RandomX's CMakeLists maps ARCH=native to -march=native, tuning the binary to
the build host: a Zen4 build emitted 746 AVX-512 instructions into
librandomx.a, and every seed reports avx512f=no, so that binary would SIGILL
inside RandomX fleet-wide -- and on any user CPU older than the build machine.
build-win.sh had the same flag, so shipped Windows binaries inherited it.
ARCH=default keeps -maes and per-file -mssse3/-mavx2, so the portable baseline
costs essentially nothing. Note build.sh skips cmake entirely when
src/RandomX/build/ exists, so a stale dir silently preserves the old ARCH.
Validated on an isolated datadir on an EPYC seed, bootstrap -> tip:
- below 3,226,000 (RandomX skipped): 91.3 blk/s (22,823 blocks / 250s)
- at/above 3,226,000 (verified): 4.7 blk/s
~19x at the boundary. The 4.7 blk/s baseline matches a same-day restore on
the old binary, corroborating it independently.
- gettxoutsetinfo at height 3,231,951 BYTE-IDENTICAL to a live node
(hash_serialized 4885c2374ef8b84c648b97d560a57cfcc99bb979142dc89c2a5ccbc90a1f1692,
222,635 txs/txouts, 15,826,352 bytes, total 667909.93689180)
- synced through all 388 new checkpoints with zero rejections
- verifychain 4 (500) and 3 (2000) both true
Binary: v1.0.3-bf3c33c53-dirty, stripped md5 fe83d70fec5b50c38bf65ea6c733ffa9
Checkpoints decay at 2,400 blocks/day; regenerating them belongs on the
release checklist.

Large template/boost-heavy TUs (e.g. asyncrpcoperation.cpp) exceed the standard
PE/COFF ~32k-section limit under mingw-w64, which makes GNU ld emit
"dangerous relocation" on .pdata and crash (SIGSEGV) at link. The bigobj COFF
variant lifts that limit; this is the same flag Bitcoin Core sets for its mingw
host. Fixes the Windows daemon cross-compile.

build-debian-package.sh warns at startup that lintian is optional, but then
called `lintian -i ...` unconditionally at the end. Under `set -e` that aborted
with exit 127 on hosts without lintian — after the .deb had already been built.
Guard the call with `command -v lintian` so the build exits 0.

The docs/packaging were largely un-rebranded Hush3 content, with several
docs stating facts that are wrong for DragonX. This rewrites them against
the verified DragonX source state.
Corrections (not just branding):
- PoW: RandomX (CPU), not Equihash/ASIC — README, overview.md, randomx.md
- Privacy: private from genesis (ac_private=1, Sapling@height1), not "as of
block 340000" — overview.md, payment-api.md
- Removed the false "coinbase must be shielded" consensus claim
(shield-coinbase.md, payment-api.md); coinbase is directly spendable
- Fixed default fee 0.0001 (was 0.0010000, 10x); stratum port 22769 (was 19031)
- datadir ~/.hush/DRAGONX, DRAGONX.conf, dragonxd/dragonx-cli/dragonx-tx,
git.dragonx.is throughout; branch model dev->dragonx
- Softened the inherited dPoW reorg claim (no live DragonX notary infra)
Packaging: fix build-debian-package.sh + gen-manpages.sh to use the dragonx
binaries/manpages; rename bash-completions to dragonx*; drop hush-arrakis-chain
from the package. Keep /usr/share/hush (hardcoded in the binary for params).
Also: README links/logo, ObsidianDragon + SilentDragonXAndroid wallets,
networking/init/dev-process/contrib/util rebrand, and leftover helper scripts.
Delete legacy duplicates (hushd.* init/service, HUSH3.conf examples,
OLD_WALLETS.md, hsc.md) and rename hush-uri.bat -> dragonx-uri.bat.
Out of scope (noted, not changed): historical changelog/copyright, the Hush
mainnet airdrop snapshot, seed data files, depends/ source mirrors, and the
in-code strCurrencyUnits="HUSH".

util/build.sh runs with `set -eu -o pipefail`. `eval "$MAKE" --version | head -n2`
(and the analogous `as --version | head`) can race: head closes the pipe after N
lines, make/as catch SIGPIPE and exit non-zero, pipefail propagates the failure,
and errexit aborts the build before any compilation. Append `|| true` so these
purely-informational version prints can never fail the build.

- Parallel RandomX PoW pre-verification pool (CCheckQueue) run ahead of the serial
connect; consensus-neutral (inline CheckRandomXSolution fallback still verifies
anything not pre-verified). New -randomxverifythreads (default = -par).
- Adaptive dbcache: default sizes the UTXO/coins cache to most of RAM and shrinks
under memory pressure, always leaving a reserve free; -dbcache pins a fixed value.
- P2P block download: bounded socket recv-drain loop (tlsmanager); frontier-block
reassignment to break head-of-line stalls (-blockreassigntimeout); ProcessGetData
serves a bounded batch of blocks per pass instead of one (fixes the serve-side
one-block-per-tick throttle that caps download network-wide).
- assumeutxo: dumptxoutset RPC + LoadSnapshot machinery + AssumeutxoData chainparams.
- Signed bootstrap verification (util/bootstrap-dragonx.sh, util/sign-bootstrap.md).
- gtest: RandomX pre-verify consensus-equivalence test + UTXO-snapshot round-trip;
revived the gtest harness (Makefile.am include fix, Makefile.gtest.include).

- Update compiler references from gcc-8 to gcc-15 across build system
(build-mac.sh, darwin.mk, Makefile_custom)
- Use system Rust (rustup) instead of bundled Rust 1.32.0 for librustzcash
to fix rlib linker incompatibility on macOS Sequoia
- Replace deprecated std::random_shuffle with std::shuffle (net.cpp,
transaction_builder.cpp, wallet.cpp)
- Fix -std=gnu17 -> -std=gnu++17 for C++ targets (libzcash, libhush)
- Fix nodiscard warning in glibcxx_sanity.cpp
- Replace deprecated OSMemoryBarrier with std::atomic_thread_fence in LevelDB
- Add -Wno-error=deprecated-declarations to CXXFLAGS for third-party headers
- Fix REMAINING_ARGS unbound variable in build.sh
- Add --disable-tests handling to build-mac.sh
- Update README with correct macOS build dependencies and instructions
Minimal rebrand (see compliant-rebrand branch for full rebrand):
- Rename binaries: hushd/hush-cli/hush-tx → dragonxd/dragonx-cli/dragonx-tx
- Default to DRAGONX chain params without -ac_* flags (randomx, blocktime=36, private=1)
- Update configure.ac: AC_INIT([DragonX],[1.0.0])
- Update client version string and user-agent to /DragonX:1.0.0/
- Add chainparams.cpp with DRAGONX network parameters
- Update build.sh, miner.cpp, pow.cpp for DragonX
- Add bootstrap-dragonx.sh utility script
- Update .gitignore for release directory
Share single RandomX dataset across all mining threads:
- Add RandomXDatasetManager with readers-writer lock, reducing RAM from
~2GB per thread to ~2GB total plus ~2MB per thread for the VM scratchpad
- Add LogProcessMemory() diagnostic helper for Linux and Windows
The build system supports using CC to control the C compiler
and CXX to control the c++ compiler used but src/cc was hardcoded
to use the binary "gcc". Now it respects the custom value of
$CC environment variable if it exists.
This allows us to see function names in a backtrace when AssertLockHeld
gives us an assert, which is helping to debug our deadlock bug.
This code should be improved to only do this for debug builds.
