- rpc_client: wipe the plaintext "user:password" temporary with sodium_memzero after
base64-encoding it into the auth header (std::string doesn't zero its buffer on
destruction).
- connection: the auto-generated DRAGONX.conf holds rpcuser/rpcpassword in plaintext but
was written with the default umask (often world-readable 0644). Restrict it to owner
read/write after creation so another local user can't read the credentials.
- app: copying a seed phrase / private key to the clipboard now arms an auto-clear —
App::copySecretToClipboard() copies the secret and, after 45s, wipes the clipboard IF it
still holds that secret (compared via a stored hash, never the plaintext). Wired into the
lite first-run wizard's seed Copy and the Settings export-secret Copy, with a
"clipboard auto-clears in 45s" notice. pumpSecretClipboardClear() runs each frame.

The connection probe (getinfo) used a 30s request timeout, so when something on
the local RPC port accepts TCP but never answers — a daemon still loading the
block index, or a wedged/foreign occupant — every attempt blocked the full 30s
before the wallet could retry or update its status. That is the "stuck, timing
out every 30s" behaviour users hit.
A healthy local daemon answers getinfo in milliseconds, and a warming one
returns -28 just as fast, so a long hang on localhost only ever means trouble.
Probe localhost with an 8s timeout (remote/TLS keeps the 30s budget). The
per-call override restores the persistent 30s afterwards, so normal RPC calls
that legitimately take longer are unaffected — only the probe fails faster, so
the wallet retries promptly and reflects "initializing" / recovery within
seconds of the daemon becoming ready.

stop()-ing a worker that is mid curl_easy_perform joined on the UI thread, so a
slow/hung transfer froze the UI until the request timeout. Add RPCClient::
requestAbort() (a thread-safe atomic read by a curl progress callback that aborts
the transfer), and call it before stopping the workers on disconnect
(onDisconnected) and shutdown (beginShutdown + the synchronous fallback). The
flag is cleared on each connect() so a fresh connection never starts aborted.

The connection state machine never tore down on a lost connection: refresh-loop
RPC errors were swallowed, rpc_->isConnected() stayed true after a daemon
crash/restart/socket drop, and the UI showed stale balances with no reconnect.
Several operations also ran synchronous curl straight from ImGui handlers.
- Add handleLostConnection(): after N consecutive cycles where BOTH core RPCs
fail (warmup excluded, so no reconnect loop), disconnect so update()'s
reconnect branch re-enters tryConnect().
- Move banPeer/unbanPeer/clearBans and key export/import onto the worker thread
(import requests a rescan that could freeze the UI for the curl timeout).
- Run the block-info dialog's two chained RPCs on the worker thread (+ guard the
getblockhash result type).
- Detect daemon warmup via the JSON-RPC -28 code (new RpcError carrying the code;
message text preserved so 401/warmup string-matching is unaffected), and widen
CONNECTTIMEOUT to 10s for remote/TLS hosts (2s localhost).

Add an encrypted SQLite transaction history cache with cached tip metadata and
per-address shielded scan progress so startup and full refreshes avoid
re-scanning every z-address while still invalidating on wallet/address/rescan
changes.
Improve wallet history loading by paging transparent transactions, preserving
cached shielded and sent rows, keeping recent/unconfirmed activity visible, and
classifying mining-address receives. Show z_sendmany opid sends immediately in
History and Overview, pin pending rows through refreshes, and apply optimistic
address/balance debits until opids resolve.
Add timestamped RPC console tracing by source/method without logging params or
results, reduce redundant refresh/RPC calls, and cache Explorer recent block
summaries in SQLite.
Expand focused tests for transaction cache encryption, scan-progress
persistence/invalidation, history preservation, operation-status parsing,
pending send visibility, and Explorer/RPC refresh behavior.
Instead of blocking the entire UI with "Activating best chain..." until
the daemon finishes warmup, treat warmup responses as a successful
connection. The wallet now:
- Sets connected=true + warming_up=true when daemon returns RPC -28
- Shows warmup status with block progress in the loading overlay
- Polls getinfo every few seconds to detect warmup completion
- Allows Console, Peers, Settings tabs during warmup
- Shows orange status indicator with warmup message in status bar
- Skips balance/tx/address refresh until warmup completes
- Triggers full data refresh once daemon is ready
Also: fix curl handle/header leak on reconnect, fill in empty
externalDetected error branch, bump version to v1.2.0 in build scripts.
- Create .github/copilot-instructions.md with project coding standards,
architecture overview, threading model, and key rules for AI sessions
- Add module description comments to app.cpp, rpc_client.cpp, rpc_worker.cpp,
embedded_daemon.cpp, xmrig_manager.cpp, console_tab.cpp, settings.cpp
- Add ASCII connection state diagram to app_network.cpp
- Remove /.github/ from .gitignore so instructions file is tracked
Mine-when-idle:
- Auto-start/stop mining based on system idle time detection
- Platform::getSystemIdleSeconds() via XScreenSaver (Linux) / GetLastInputInfo (Win)
- Settings: mine_when_idle toggle + configurable delay (30s–10m)
- Settings page UI with checkbox and delay combo
Console tab:
- Shell-like argument parsing with quote and JSON bracket support
- Pass JSON objects/arrays directly as RPC params
- Fix selection indices when lines are evicted from buffer
Connection & status bar:
- Reduce RPC connect timeout to 1s for localhost fast-fail
- Fast retry timer on daemon startup and external daemon detection
- Show pool mining hashrate in status bar; sidebar badge reflects pool state
UI polish:
- Add logo to About card in settings; expose logo dimensions on App
- Header title offset-y support; adjust content-area margins
- Fix banned peers row cursor position (rawRowPosB.x)
Branding:
- Update copyright to "DragonX Developers" in RC and About section
- Replace logo/icon assets with updated versions
Misc:
- setup.sh: checkout dragonx branch before pulling
- Remove stale prebuilt-binaries/xmrig/.gitkeep
Diagnostics & logging:
- add verbose logging system (VERBOSE_LOGF) with toggle in Settings
- forward app-level log messages to Console tab for in-UI visibility
- add detailed connection attempt logging (attempt #, daemon state,
config paths, auth failures, port owner identification)
- detect HTTP 401 auth failures and show actionable error messages
- identify port owner process (PID + name) on both Linux and Windows
- demote noisy acrylic/shader traces from DEBUG_LOGF to VERBOSE_LOGF
- persist verbose_logging preference in settings.json
- link iphlpapi on Windows for GetExtendedTcpTable
Security & encryption:
- update local encryption state immediately after encryptwallet RPC
so Settings reflects the change before daemon restarts
- show notifications for encrypt success/failure and PIN skip
- use dedicated RPC client for z_importwallet during decrypt flow
to avoid blocking main rpc_ curl_mutex (which starved peer/tx refresh)
- force full state refresh (addresses, transactions, peers) after
successful wallet import
Network tab:
- redesign peers refresh button as glass-panel with icon + label,
matching the mining button style
- add spinning arc animation while peer data is loading
(peer_refresh_in_progress_ atomic flag set/cleared in refreshPeerInfo)
- prevent double-click spam during refresh
- add refresh-button size to ui.toml
Other:
- use fast_rpc_ for rescan polling to avoid blocking on main rpc_
- enable DRAGONX_DEBUG in all build configs (was debug-only)
- setup.sh: pull latest xmrig-hac when repo already exists
RPC client:
- Add call() overload with per-call timeout parameter
- z_exportwallet uses 300s, z_importwallet uses 1200s timeout
Decrypt wallet (app_security.cpp, app.cpp):
- Show per-step and overall elapsed timers during decrypt flow
- Reduce dialog to 5 steps; close before key import begins
- Run z_importwallet on detached background thread
- Add pulsing "Importing keys..." status bar indicator
- Report success/failure via notifications instead of dialog
RPC caching (app_network.cpp, app.h):
- Cache z_viewtransaction results in viewtx_cache_ across refresh cycles
- Skip RPC calls for already-cached txids (biggest perf win)
- Build confirmed_tx_cache_ for deeply-confirmed transactions
- Clear all caches on disconnect
- Remove unused refreshTransactions() dead code
Peers (app_network.cpp, peers_tab.cpp):
- Route refreshPeerInfo() through fast_worker_ to avoid head-of-line blocking
- Replace footer "Refresh Peers" button with ICON_MD_REFRESH in toggle header
- Refresh button triggers both peer list and full blockchain data refresh
Mining (mining_tab.cpp):
- Allow pool mining toggle when blockchain is not synced
- Pool mining only needs xmrig, not local daemon sync
