This is what "up to date" means here -- not the 1.2.2x tags, which carry higher version numbers but were cut 2026-07-30, three weeks before the line we ship, and which upstream/main does not contain. Three conflicts, all resolved toward upstream's structure while keeping what this fork knows: main.cpp -- upstream moved genesis construction into BuildGenesisBlock() so mainnet and the new testnet can share it. Verified byte-for-byte before taking it: MAINNET_GENESIS_TIMESTAMP, _TIME (1753315200), _NONCE (3141), _HASH, _MERKLE, the scriptPubKey, nBits and nVersion all equal what this tree built inline. The mainnet genesis hash is unchanged and the asserts still guard it. Kept our warning about never editing those inputs, and kept our note that 1753315200 is 2025-07-24, not 2026 -- upstream's comment on that constant states the wrong year. net.h -- DEFAULT_PORT = htons(8433) becomes MAINNET_PORT/TESTNET_PORT in host order. Nothing is lost: net.cpp's GetDefaultPort() applies htons() itself and is what every caller uses, so the value reaching a sockaddr is unchanged and mainnet stays on 8433. selftest.cpp -- the known-tests string had diverged in both directions. Took the union: upstream's network-params alongside our payout-ledger, rather than dropping either. Gates: 15/15 selftests (our 14 plus upstream's network-params), consensus constants unchanged against e4f898c except the pre-existing MAX_BLOCK_SIZE_GEN, mainnet genesis intact, compactblock's 17 checks still pass, money-log check ok, GNU_STACK RW. 2026-09-05T03:16:12+00:00 bitflash-maintainer noreply@bitflash.invalid 2026-09-05T03:16:12+00:00 urn:sha1:36201d2795b7b49beb1a837b0252134096beb64d Two fixes to the file imported in the previous commit. Kept separate so the deviation from upstream's bytes is reviewable on its own. BuildCompactBlock ignored the RAND_bytes return value. On failure nonceBytes is left uninitialised and an indeterminate shortIdNonce is memcpy'd out and sent on the wire -- and that nonce is exactly what the file relies on being unpredictable so short IDs cannot be precomputed before a block exists or ground across blocks. Every other RAND_bytes call site in this tree (bip32.cpp:203, db.cpp:2462, db.cpp:2469) checks for != 1 and fails closed; this one now does too. The caller falls back to full-block relay. TryReconstructBlock sized a vector directly from the wire. nTotal is the sum of two deserialised vector lengths, and serialize.h bounds a vector only by MAX_SIZE (0x02000000), so once the P2P handlers are wired a single small message could ask this node to default-construct ~33M CTransactions. The smallest a transaction can serialise to is 10 bytes, so no block within MAX_BLOCK_SIZE holds more than MAX_BLOCK_SIZE/10 of them; anything above that is not a block this node could accept under any circumstance. Rejecting falls back to full-block relay, which is always correct. Neither is reachable today -- nothing feeds these functions from the network yet -- but both are latent the moment the message handlers land, which is the wrong time to be finding them. test_compactblock (17 checks) and all 14 selftests pass with both in place. 2026-09-05T03:16:00+00:00 bitflash-maintainer noreply@bitflash.invalid 2026-09-05T03:16:00+00:00 urn:sha1:60538c5a935787521a5ad8c2a7dce52b5f250f3a Brings src/compactblock.{cpp,h} and test_compactblock.cpp across verbatim from the upstream-v1.2.23 tag, and gives them a build. 1.2.23 is not a newer release of the line this fork ships. It is a lightweight tag (7ab5a8c) cut 2026-07-30, on a lineage that upstream/main (e0be70e, 2026-08-20) does not contain and no remote branch carries -- 272 commits that are not ours, against 376 of ours that are not theirs, from a merge-base at 56df983. Merging that tag would have deleted 18 files from src/, selftest.{cpp,h} and the whole 14-test suite among them, so the content is ported file by file instead. Compact block relay is the piece worth having: a peer that advertises sendcmpct gets 48-bit keyed short IDs per transaction rather than the transaction bytes, and reconstructs the block from its own mempool. It is purely additive on the wire -- a peer that never sends sendcmpct keeps receiving full block messages, so no coordinated upgrade is needed. This commit is the primitives and their unit test only. Nothing calls BuildCompactBlock or TryReconstructBlock yet: the P2P message handlers (sendcmpct/cmpctblock/getblocktxn/blocktxn) live in 1.2.23's main.cpp and are deliberately left for a follow-up, so that no attacker-controlled bytes reach this code until that wiring is reviewed on its own. The files needed no API adaptation -- mapTransactions, BEGIN/END and IMPLEMENT_SERIALIZE are unchanged across the divergence, and it compiled clean first time. Upstream never wired test_compactblock.cpp into its own Makefile, so it had never been built there; it links standalone the way test_bip32 does, supplying its own mapTransactions and GetAppDir to keep main.cpp out of the link. TEST_LIBS is overridable for the same reason NODE_LIBS is: the pinned dep tree ships libsodium as a static archive only. All 17 checks in test_compactblock pass, all 14 selftests still pass, and the consensus constants are unchanged against e4f898c. 2026-09-03T22:33:20+00:00 bitflash-maintainer noreply@bitflash.invalid 2026-09-03T22:33:20+00:00 urn:sha1:b810d86752ddb2674118f737582c924bb9eb74c1 # Conflicts: # Makefile 2026-09-03T21:49:35+00:00 bitflash-maintainer noreply@bitflash.invalid 2026-09-03T21:49:35+00:00 urn:sha1:db44eac5d347c229539946e8d61f1ff0d1f68001 2026-09-03T21:49:35+00:00 bitflash-maintainer noreply@bitflash.invalid 2026-09-03T21:49:35+00:00 urn:sha1:cb8fb6d9d14ecf96b4a71ccc1a51b87bf8dd9bd5 2026-09-03T21:49:35+00:00 bitflash-maintainer noreply@bitflash.invalid 2026-09-03T21:49:35+00:00 urn:sha1:aadf093313b55f1ab08671068471eedf6fb0445c 2026-09-03T21:49:35+00:00 bitflash-maintainer noreply@bitflash.invalid 2026-09-03T21:49:35+00:00 urn:sha1:4b3069f2de140cda427627d470f2751609be6620 2026-09-03T21:49:35+00:00 bitflash-maintainer noreply@bitflash.invalid 2026-09-03T21:49:35+00:00 urn:sha1:ea8fe94658bf20d2b669b619231238f12e6bd8fc 2026-09-03T21:49:35+00:00 bitflash-maintainer noreply@bitflash.invalid 2026-09-03T21:49:35+00:00 urn:sha1:944f93f163cb560f095556834b6eb75bfde60c9c
