The macOS build of e2cd0b6 (the NeedsBootstrap rocksdb/ fix) failed at
the 'Bundle Tor into app' step with bash exit code 6 after exactly 30s
of curl hanging against archive.torproject.org. All 4 Tor download
sites (Windows Qt, Windows daemon, Linux Qt .deb, Linux daemon .deb,
macOS Qt) used 'curl -sL' with no timeouts and no retries — a single
transient network drop from Azure westus to the Tor archive killed
the job.
Fix at all 4 sites:
* curl -fSL (HTTP error -> non-zero exit; fail loudly)
* --connect-timeout 15 / --max-time 120 (per-attempt bounds)
* --retry 3 --retry-delay 5 --retry-connrefused --retry-all-errors
(covers 5xx, DNS timeouts, and connection refused)
* 'set -euo pipefail' at script top so any failure aborts cleanly
* PowerShell variants get a manual retry loop with size check
(1MB minimum — a 0-byte '200 OK' response from a broken mirror
used to silently slip through)
Also bump CLIENT_VERSION_REVISION 1 -> 4 (v6.1.4) for the upcoming
release that will include e2cd0b6 (NeedsBootstrap rocksdb/ fix).
Release notes:
v6.1.4: Tor bundle download resilience (4 CI sites hardened)
+ e2cd0b6 (NeedsBootstrap rocksdb/ chain state detection). Supersedes
v6.1.3 only on CI reliability; no protocol/wallet/chain format changes.
Adds v3 snapshot format that includes the last 5000 PoS block
(prevoutStake, nStakeTime) pairs so a snapshot-loaded node has its
stake-collision set restored without walking the block index.
v2 readers still load v3 snapshots (the extra field is past numBlocks
and the loader checks version >= 3 to read numStakeSeen).
Bumps version to 6.1.1.
SQLite wallet (default), RocksDB chaindb (default), Boost removal
from common link, I2P startup performance fix (180s→27ms).
Migration is automatic and non-destructive:
- Wallet: BDB → SQLite on first open (original preserved as .bdb.bak)
- ChainDB: LevelDB → RocksDB on next start (via -chaindb flag)
Merges the HD wallet work and process-based I2P integration from the
SAMI-PC hd-wallet branch into v6 master. Conflict resolution keeps
v6 embedded I2P (CI2PEmbedded) as primary, includes process-I2P
files for reference, preserves FastImportBlockFile() from hd-wallet,
and keeps v6 version numbers (6.0.0) and wAddressStack Qt layout.
The Dockerfile in packaging/docker/ downloads the daemon .deb from
the release URL during the build. On tag-push, the release record is
created immediately but the .deb asset gets uploaded a few seconds
to minutes later by the build job.
Race condition seen on v5.9.24 distribute run #24 (2026-06-24 01:10 UTC):
- Workflow fired on tag push
- Docker Hub job started step 5 'Build and push' immediately
- Dockerfile's curl returned 404 for the .deb
- Job failed in 18 seconds; release .deb was uploaded ~8 min later
AUR and WinGet jobs already had this wait step; Docker Hub was the
only one missing it. Added the same pattern (poll for URL reachability
up to 30 * 20s = 10 min).
Three pure helper functions extracted from ThreadHTTPSeedFetch2 into
netbase.{h,cpp} so the HTTPS seed-list code path can be unit-tested
without the SSL/Tor network stack:
int DechunkTransferEncoding(const std::string& body, std::string& out)
std::vector<std::string> ParseSeedListBody(const std::string& body)
bool IsValidSocksNegotiationTimeout(int nMs)
DechunkTransferEncoding is now strict (was lenient):
- Hex validation: every byte of the chunk-size line is checked with
isxdigit() before strtoull. Old code passed a raw strtoul() result
which silently accepted leading '+', '-', and whitespace.
- strtoull + errno + size_t bounds check replaces the silent
'if (pos+chunkSize > body.size()) chunkSize = body.size()-pos'
clamp. The old behavior would mask truncated network reads.
- Empty size lines, '+5' / '-5' / ' 5', and unsigned overflow all
return DECHUNK_INVALID_HEX (or DECHUNK_OVERSIZE_CHUNK for the
bounds case) instead of being treated as 0/last-chunk.
- Missing CRLF after chunk data returns DECHUNK_MISSING_DATA_CRLF
rather than being read as the next chunk-size line.
- Body without a '0\r\n' last-chunk terminator returns
DECHUNK_NO_CHUNK_TERMINATOR instead of silently being accepted.
- Chunk extensions ('5;foo=bar') are still preserved — the ';'
delimiter is stripped from the size line, not from the framing.
ParseSeedListBody is a 1:1 extraction of the old loop. Same behavior
on every input. Trims inline '#' comments, splits on whitespace /
comma / semicolon, normalizes CR-only line endings.
IsValidSocksNegotiationTimeout is the central policy: 5000..180000 ms
inclusive. Replaces the inline 'nTorTimeout >= 5000 && nTorTimeout <=
180000' check in init.cpp's AppInit2. Out-of-range values now emit an
InitWarning so the operator sees why their setting was ignored.
Six distinct failure-mode log messages in ThreadHTTPSeedFetch2:
1. 'cannot connect to %s through Tor proxy' — connect failure
2. 'malformed response (no header terminator)' — no \r\n\r\n
3. 'malformed chunked transfer encoding (%s)' — DechunkResult enum
reason string
4. 'empty response from %s' — 0 bytes read
5. 'parsed response contained zero valid addresses' — body parsed
but CService
validation
dropped all
6. '%d addresses found from HTTPS seed list' — success path
Help text for -torconnecttimeout now precisely describes what the
value bounds (the SOCKS5 handshake — send/recv of init/auth/connect),
not 'time to reach the onion' which was misleading. The onion-resolution
time is bounded by Tor's own SocksTimeout (~120s) and is not directly
controllable from the daemon.
src/test/http_seed_tests.cpp adds 43 new Boost.Test cases covering
every scenario in the hardening brief:
DechunkTransferEncoding: 16 cases
- single chunk, multiple chunks, chunk extensions (one and
multiple), uppercase hex, payload containing CRLF, awkward
boundary that looks like a chunk-size line, last-chunk with
extension
- empty body, no CRLF after size, invalid hex, empty size line,
oversize chunk, truncated last-chunk marker, missing data CRLF,
strtoul overflow, sign in size, whitespace in size, no last
chunk
ParseSeedListBody: 14 cases
- empty, single-per-line, CRLF endings, multiple-per-line
(space, comma, semicolon, mixed), inline comments, blank lines,
all-comments, portless onion, invalid entry preserved, trailing
whitespace, mixed CRLF/LF
IsValidSocksNegotiationTimeout: 9 cases
- 4999 (out), 5000 (in, exact lower), 60000 (in, default), 180000
(in, exact upper), 180001 (out), 0 (out), -1 (out), INT_MAX
(out, guard against wraparound), 3 midrange values
Integration: 1 round-trip case
- Encode a seed body as chunked, dechunk it, then parse the
result. Verifies the two helpers compose correctly.
Test results: 183 test cases total, *** No errors detected. Existing
onion_v3_tests (8) and netbase_tests (10) still pass.
The HD seed action was only added to the standard Qt menu bar, which the
skinned GUI hides. Add it to menuOperationsRequested() so users can actually
reach Generate / Reveal-for-backup / Restore from the Operations menu.
Two related bugs in the getheaders handler at main.cpp:4441:
1. Locator-mismatch returns 0 headers:
GetBlockIndex() falls through to pindexGenesisBlock when no locator
hash matches the main chain. pindexGenesisBlock->pnext is null, so
the for-loop exits immediately and the peer gets an empty headers
response. This was the DNS3 headers-first sync stall (pitfall #36):
'getheaders -1 to 0000...' logged repeatedly.
Mirror the getblocks handler (line 4387): detect the mismatch, log
a warning, and serve headers from genesis so the peer can discover
the canonical chain.
2. Broken pnext chain at any height:
Even when GetBlockIndex() returns a valid (non-genesis) block, its
pnext can be null — this happens when LoadBlockIndex() didn't fully
heal pnext links (e.g., the node was bootstrapped from a snapshot,
or the chain was interrupted by a crash). On tridock every pnext
link was null despite 2.2M blocks (the June 11 'Heal pnext links'
commit addressed a similar symptom for GetKernelStakeModifier() but
doesn't reach into the getheaders handler).
Fall back to a tip-backwards walk from pindexBest when pnext is
null: O(N) but correct, and only triggers on the broken path.
(References the design in references/getheaders-pnext-fix.md from
the v5.9.10 deploy notes — that fix was never actually committed,
only prototyped and dropped during the June 4 git cleanup.)
Bump to v5.9.14 (also embeds the embedded-Tor 0700 fix from ed996c8).
Refs: SKILL.md pitfall #36
Closes the unchecked span from block 17650 to the live tip. Nodes now
reject stale-bootstrap / low-trust forks below 2205000. Hash taken from
the canonical chain (PC wallet, verified via getblockhash).
Internal refactor milestone for the C++20 modernization series.
No protocol or on-disk format change (version.h untouched).

M1.2 (mechanical):
Convert every CTxDB& parameter and reference across main.{h,cpp},
wallet.{h,cpp}, and smessage.cpp to CTxDBBase&. Local instantiations
like `CTxDB txdb("r");` are deliberately left as concrete LevelDB —
they'll move behind a factory in M1.4 once the parity harness exists.
CTxDB IS-A CTxDBBase, so all existing call sites continue to compile:
a CTxDB instance binds to a CTxDBBase& parameter automatically.
Forward declaration `class CTxDB;` in main.h replaced with
`class CTxDBBase;`.
Parallel work (snapshotnet + version bump to 5.9.4 + checkpoints/init
/protocol/version edits) included so origin/master matches the local
working tree in one push.
NOT YET COMPILE-TESTED: pushed at the user's explicit request before
the build verification step. If CI fails, expected breakage is in
files that include main.h transitively but not txdb-base.h — fix is
to add `#include "txdb-base.h"` (or rely on the existing txdb.h which
pulls it in).

Pairs net.h heartbeat-throttle field with the IBD header-sync fix
in 2a484e4, and ships a full RPC reference doc.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Nodes syncing from zero would accept blocks normally up to ~6000 then
stall permanently with askfor_queue=0 and no new blocks. Root cause: a
broken feedback loop between the header planner and block downloader.
Blocks consume entries from mapHeaderSync (MAX 15000) while getheaders
refills only 2000 at a time; when the cache drains, hashBestHeaderSync
falls to 0 and every refill site is guarded on it being non-zero, so
the pipeline deadlocks with no recovery path.
Recovery paths added:
- ProcessBlock: when the cache is empty during IBD after accepting a
block, broadcast getheaders to all full-node peers. This restarts
the planner at the exact point it dies.
- Stall detection: send getheaders alongside the existing getblocks.
getblocks alone cannot refill the header cache.
- SendMessages: belt-and-suspenders, re-request headers every 30s
while hashBestHeaderSync == 0 in IBD, independent of stall state.
Also fix a secondary issue: GetHeaderSyncDownloadPath walks back from
the tip and breaks on the first TTL-evicted entry. The accumulated
partial tail has a parent that is neither in mapBlockIndex nor
mapHeaderSync, so requesting those blocks would produce orphans.
Discard the partial path on a gap; the recovery paths above will
re-request the missing range.

Follow-up to #5. Addresses three risks with the apply=true path:
- MoneyRange sanity gate: refuse to persist a recalculated supply that is
negative or above MAX_MONEY (2,222,222 TRI). A walk that produces an
out-of-range figure indicates a bug (orphan contamination, missing
prevout), not real chain state. Prevents corrupting nMoneySupply with
junk values.
- Atomic apply: wrap every per-block WriteBlockIndex in a single
TxnBegin/TxnCommit so a mid-walk failure leaves on-disk state
untouched instead of half-rewritten.
- Single chain walk: cache (valueOut - valueIn) per block during the
dry-run pass and reuse the cached deltas during apply. Previous code
walked the full chain twice, roughly doubling apply runtime on a
2.2M-block chain.
Help text now warns that the RPC holds cs_main for the full walk and
blocks new blocks, wallet ops, and other RPC for the duration.

Replace FutureDrift(GetAdjustedTime()) with GetTime() + 15min in CheckBlock
and header-sync validation. GetAdjustedTime() incorporates peer-reported
time offsets that vary between Tor nodes, causing the same block to be
accepted by some nodes and rejected by others — the primary cause of
persistent chain forks. AcceptBlock still enforces tight 3-min drift rules
deterministically against the previous block timestamp.

Three fixes for the fork-oscillation problem where same-version nodes
keep disagreeing on the chain tip:
1. Prune setStakeSeen on reorg — disconnected PoS blocks' stake entries
were never removed, blocking acceptance of valid competing blocks
and preventing chain convergence after reorganizations.
2. Remove global nBestHeight from PastDrift/FutureDrift — the no-argument
overloads used the mutable global nBestHeight to decide between 3-min
and 10-min timestamp drift at the V5.4 fork boundary (block 2186941).
Nodes at different heights applied different validation rules to the
same block, causing a permanent consensus split. Now always uses
post-fork 3-min rules since all nodes are well past the fork.
3. Anti-oscillation for equal-trust reorgs — the hash-based tiebreaker
now only fires for shallow forks (parent in main chain). Deep forks
with equal trust no longer trigger reorgs, preventing the Tor-latency-
induced ping-pong where nodes flip between competing chains.

- Daemon: automatically downloads blockchain snapshot when no data exists
No -bootstrap flag needed. Use -nobootstrap to skip.
- Qt wallet: auto-bootstraps on first run (no question asked)
Existing users still get the optional re-download prompt.
- New users just install and run - blockchain downloads automatically
- Works on all platforms (Windows, Linux, macOS, ARM64)
- Hardcoded DNS3 (74.208.167.19), DNS2 (194.233.88.206), and Contabo (100.98.123.59) as fixed seeds
- Nodes will automatically connect to these on first run
- No manual addnode configuration needed
- Full mesh network connectivity built into the code
The Tor v3 spec requires SHA3-256 (FIPS-202) for the .onion address
checksum computation, but ToStringIP() was using SHA-256 (double-hash).
This caused every reconstructed .onion address to have incorrect suffix
characters, making all outbound Tor connections fail with SOCKS5 'general
failure' - the entire network had 0 Tor peers despite working Tor instances.
Fix: Replace Hash() call with OpenSSL EVP_sha3_256() which is available
in OpenSSL 3.0+ and produces the correct FIPS-202 SHA3-256 checksum.
Tested: All 5 onion seed nodes now connect successfully.
Replace all hardcoded seed addresses (onion, clearnet, DNS) with a
dynamic HTTP-based seed list fetched from seeds.cryptographic-triangles.org
on startup. New getseedlist RPC exposes known .onion peers from the
address manager for a collector script to publish.
Any wallet that comes online with an onion address is automatically
discovered by peers via P2P addr exchange and appears in the seed list
within minutes. No binary rebuilds needed when addresses change.
