From 8c014991265f2b901b4a66e56b0aad59af21e401 Mon Sep 17 00:00:00 2001 From: Sameh Farouk Date: Fri, 6 Mar 2026 23:58:18 +0000 Subject: [PATCH 01/49] fix(bridge): add batching for withdraw proposals and idempotency for crash safety MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Addresses two bridge reliability issues: **Batching (#1053):** - Reorder event loop to process Ready events (time-sensitive, ~2 min signature expiry) before Created events - Batch WithdrawCreated proposals into a single Utility.batch extrinsic, reducing N×6s sequential processing to 1×6s - Add BatchCalls helper to tfchain-client-go using Utility.batch (not batch_all) so individual failures don't abort the entire batch - Falls back to individual submissions if batch fails **Atomicity (#1054):** - Add bbolt-backed IdempotencyStore tracking PROCESSING/COMPLETED state per transaction, preventing double Stellar submissions on crash - Add Horizon memo lookup (FindPaymentByMemo, FindRefundByReturnHash) for crash recovery — checks if Stellar tx already exists before retry - Add startup reconcilePendingTransactions that resolves any transactions left in PROCESSING state from a previous run - Fix pre-existing bug: errors.Wrap used outer-scope err instead of data.Err in both tfchainSub and stellarSub error handling Co-Authored-By: Claude Opus 4.6 ---

FindPaymentByMemo (used in reconcilePendingTransactions) searches for memo_type=text but found nothing, making the 'already submitted' detection path always fail. Root cause: memo was never set on withdraw payments (only refunds used MemoReturn). Additionally, the memo must be set at SIGNING time (CreatePaymentAndReturnSignature) as well as submission time — because the Stellar tx hash is computed over all fields including memo. Setting it only at submission causes signature verification failures since validators signed a different hash. Fix: - Add txnBuild.Memo = txnbuild.MemoText(fmt.Sprint(txID)) to CreatePaymentAndReturnSignature so the signed hash includes the memo - Add txnBuild.Memo = txnbuild.MemoText(txHash) to CreatePaymentWithSignaturesAndSubmit for consistency After fix: all Stellar withdraw txs have memo_type=text with the burn tx ID, enabling reliable crash recovery via Horizon memo lookup.

The log file stayed empty for minutes despite the process running. +**Root cause:** `--print` mode is a one-shot text generation mode — it outputs a response but does NOT execute shell commands or use tools. It's equivalent to asking Claude a question in text mode. +**Workaround:** Use interactive TUI mode (without `--print`) with `pty:true`. This is the mode where Claude Code actually runs bash commands, edits files, etc. + +**Correct pattern:** +```bash +cd /project && claude --dangerously-skip-permissions "task description" +# pty:true, background:true, yieldMs:15000+ +# Then accept bypass prompt: send-keys ["down", "enter"] +``` + +--- + +## 3. PTY Broken by Output Pipe + +**Phase:** Agent spawning +**Issue:** First PTY-mode attempt appended `| head -20` to the command. The agent session showed no output, bypass prompt couldn't be accepted. +**Root cause:** Piping stdout of an interactive PTY application (`| head -20`) breaks the terminal allocation. The PTY requires a direct terminal connection — piping severs it. +**Workaround:** Never pipe the output of a PTY coding agent command. Monitor it via `process log` / `process poll` instead. + +--- + +## 4. Claude Code Auto-Updated Mid-Session and Stalled + +**Phase:** Implementation (after code writing completed) +**Issue:** After successfully writing all code files and passing `go vet`, the agent output showed `Auto-updating…` and then went idle at the prompt. It did not continue to the build/test phase. +**Root cause:** Claude Code triggered an automatic self-update (`✳ Claude Code` icon change). After updating, the session was left at the interactive prompt with no pending task. +**Workaround:** Detect the stall (via `process poll` returning "still running" but no progress), then use `process send-keys` with `literal` to inject the next instruction into the running session: +``` +process send-keys literal:"Continue from Phase 1: build the substrate node..." +process send-keys keys:["enter"] +``` + +--- + +## 5. Rust Not on PATH in Agent's Shell Environment + +**Phase:** Rust build +**Issue:** Agent ran `rustc --version` and got `command not found` (exit 127), even though Rust is installed via rustup. +**Root cause:** The agent's shell environment doesn't source `~/.bashrc` or `~/.cargo/env` automatically. Rustup installs to `~/.cargo/bin` but this isn't in the default PATH for non-interactive shells. +**Workaround:** Prefix all cargo/rustc commands with the explicit PATH: +```bash +export PATH="$HOME/.cargo/bin:$HOME/sdk/go/bin:$HOME/go/bin:$PATH" +cargo build ... +``` + +--- + +## 6. `cargo build` Output Tail Misleading + +**Phase:** Rust build +**Issue:** Running `cargo build 2>&1 | tail -20` in background appeared to complete instantly with exit code 0, but no binary existed. +**Root cause:** The `tail -20` subprocess exited after receiving the first 20 lines of output, causing the pipe to close and `cargo build` to receive SIGPIPE.

Pre-existing Bug Found During Implementation + +**Phase:** Code review / implementation +**Issue:** In `bridge/tfchain_bridge/pkg/bridge/bridge.go`, the event loop error handling used: +```go +return errors.Wrap(err, "failed to get tfchain events") +``` +But `err` at that point is `nil` (from the outer scope). The actual error is `data.Err`. +**Fix:** Changed to: +```go +return errors.Wrap(data.Err, "failed to get tfchain events") +``` +**Impact:** Without this fix, tfchain subscription errors would be silently swallowed, making the bridge appear to run normally while it's actually not processing events. + +--- + +## 9. `defer idempotency.Close()` Placement + +**Phase:** Code review +**Issue:** Initial implementation placed `defer idempotency.Close()` inside a function that could return early, leaving the bbolt DB open. +**Fix:** Moved the defer to `NewBridge()` return path and added explicit close in the `Start()` shutdown path. + +--- + +## 10. `ItemFailed` Index Mapping in Batch Result Parsing + +**Phase:** Implementation — batch.go +**Issue:** When parsing `Utility_ItemFailed` events from a batch extrinsic, the initial implementation used the event index directly to map back to the original call index. This is wrong — `ItemFailed.index` is the call index within the batch, not the event position. +**Fix:** Used `event.ItemFailed.Index` (the field on the event struct) directly as the failed call index, which correctly maps to the original slice of calls. + +--- + +## 11. Stellar Testnet TFT Faucet Has No Liquidity + +**Phase:** Testnet account funding +**Issue:** `stellar-utils faucet --secret ` failed with a path payment error. The DEX path swap (XLM → TFT) found no matching orders. +**Root cause:** Stellar testnet DEX has zero TFT liquidity. The official ThreeFold testnet TFT issuer (`GA47YZA3PKFUZMPLQ3B5F2E3CJIB57TGGU7SPCQT2WAEYKN766PWIMB3`) doesn't actively maintain testnet DEX orders, so path payment swaps always fail. +**Workaround:** Create a custom TFT issuer on testnet: +1.

Stellar Memo Not Set on Withdraw Transactions (Bug Found During Testing) + +**Phase:** Crash recovery testing +**Issue:** Crash recovery relies on `FindPaymentByMemo` to check if a Stellar withdrawal was already submitted before the bridge crashed. During testing, the reconciliation consistently returned "no Stellar tx found" even when the Stellar tx WAS submitted. +**Root cause:** `CreatePaymentWithSignaturesAndSubmit` submitted Stellar transactions without setting a memo field. `FindPaymentByMemo` searches for `memo_type=text` but found nothing, because withdrawals went out with no memo at all. + +Additionally, when the memo was added only to the submission function and not the signing function (`CreatePaymentAndReturnSignature`), the signature verification failed — because the Stellar tx hash is computed over all transaction fields including memo. Validators signed a hash without the memo; submission with memo produced a different hash; signatures were invalid. + +**Fix:** Added `txnBuild.Memo = txnbuild.MemoText(fmt.Sprint(txID))` to **both** `CreatePaymentAndReturnSignature` and `CreatePaymentWithSignaturesAndSubmit`.

Only `userAcceptTc` + `createTwin` (regular signed calls) are required. - -**Where confirmed:** `substrate-node/node/src/chain_spec.rs` → `testnet_genesis()` → `TFTBridgeModuleConfig` block. - ---- - -## 2. `claude --print` Mode Doesn't Execute Code - -**Phase:** Agent spawning -**Issue:** First attempt used `claude --dangerously-skip-permissions --print "$(task)"` piped to `nohup`. The log file stayed empty for minutes despite the process running. -**Root cause:** `--print` mode is a one-shot text generation mode — it outputs a response but does NOT execute shell commands or use tools. It's equivalent to asking Claude a question in text mode. -**Workaround:** Use interactive TUI mode (without `--print`) with `pty:true`. This is the mode where Claude Code actually runs bash commands, edits files, etc. - -**Correct pattern:** -```bash -cd /project && claude --dangerously-skip-permissions "task description" -# pty:true, background:true, yieldMs:15000+ -# Then accept bypass prompt: send-keys ["down", "enter"] -``` - ---- - -## 3. PTY Broken by Output Pipe - -**Phase:** Agent spawning -**Issue:** First PTY-mode attempt appended `| head -20` to the command. The agent session showed no output, bypass prompt couldn't be accepted. -**Root cause:** Piping stdout of an interactive PTY application (`| head -20`) breaks the terminal allocation. The PTY requires a direct terminal connection — piping severs it. -**Workaround:** Never pipe the output of a PTY coding agent command. Monitor it via `process log` / `process poll` instead. - ---- - -## 4. Claude Code Auto-Updated Mid-Session and Stalled - -**Phase:** Implementation (after code writing completed) -**Issue:** After successfully writing all code files and passing `go vet`, the agent output showed `Auto-updating…` and then went idle at the prompt. It did not continue to the build/test phase. -**Root cause:** Claude Code triggered an automatic self-update (`✳ Claude Code` icon change). After updating, the session was left at the interactive prompt with no pending task. -**Workaround:** Detect the stall (via `process poll` returning "still running" but no progress), then use `process send-keys` with `literal` to inject the next instruction into the running session: -``` -process send-keys literal:"Continue from Phase 1: build the substrate node..." -process send-keys keys:["enter"] -``` - ---- - -## 5. Rust Not on PATH in Agent's Shell Environment - -**Phase:** Rust build -**Issue:** Agent ran `rustc --version` and got `command not found` (exit 127), even though Rust is installed via rustup. -**Root cause:** The agent's shell environment doesn't source `~/.bashrc` or `~/.cargo/env` automatically. Rustup installs to `~/.cargo/bin` but this isn't in the default PATH for non-interactive shells. -**Workaround:** Prefix all cargo/rustc commands with the explicit PATH: -```bash -export PATH="$HOME/.cargo/bin:$HOME/sdk/go/bin:$HOME/go/bin:$PATH" -cargo build ... -``` - ---- - -## 6. `cargo build` Output Tail Misleading - -**Phase:** Rust build -**Issue:** Running `cargo build 2>&1 | tail -20` in background appeared to complete instantly with exit code 0, but no binary existed. -**Root cause:** The `tail -20` subprocess exited after receiving the first 20 lines of output, causing the pipe to close and `cargo build` to receive SIGPIPE. Cargo may have partially compiled but the binary wasn't produced. -**Workaround:** Run cargo build without piping. Log full output to a file if needed: -```bash -cargo build > /tmp/cargo_build.log 2>&1 -# or just: cargo build 2>&1 (let it stream to the PTY) -``` - ---- - -## 7. `openclaw cron add` Missing Required Flags - -**Phase:** Scheduling the progress reminder -**Issue:** Multiple iterations needed to get the cron command right: - -- Missing `--name` flag → error -- Used `--prompt` (doesn't exist) → error -- Used `--exact` with `--every` (only valid with `--cron`) → error -- Used `--session main` without `--system-event` → error - -**Workaround:** Correct flags for an isolated agent cron job with Telegram delivery: -```bash -openclaw cron add \ - --name "job-name" \ - --every "15m" \ - --session isolated \ - --message "task description" \ - --channel telegram \ - --announce -``` - ---- - -## 8. Pre-existing Bug Found During Implementation - -**Phase:** Code review / implementation -**Issue:** In `bridge/tfchain_bridge/pkg/bridge/bridge.go`, the event loop error handling used: -```go -return errors.Wrap(err, "failed to get tfchain events") -``` -But `err` at that point is `nil` (from the outer scope). The actual error is `data.Err`. -**Fix:** Changed to: -```go -return errors.Wrap(data.Err, "failed to get tfchain events") -``` -**Impact:** Without this fix, tfchain subscription errors would be silently swallowed, making the bridge appear to run normally while it's actually not processing events. - ---- - -## 9. `defer idempotency.Close()` Placement - -**Phase:** Code review -**Issue:** Initial implementation placed `defer idempotency.Close()` inside a function that could return early, leaving the bbolt DB open. -**Fix:** Moved the defer to `NewBridge()` return path and added explicit close in the `Start()` shutdown path. - ---- - -## 10. `ItemFailed` Index Mapping in Batch Result Parsing - -**Phase:** Implementation — batch.go -**Issue:** When parsing `Utility_ItemFailed` events from a batch extrinsic, the initial implementation used the event index directly to map back to the original call index. This is wrong — `ItemFailed.index` is the call index within the batch, not the event position. -**Fix:** Used `event.ItemFailed.Index` (the field on the event struct) directly as the failed call index, which correctly maps to the original slice of calls. - ---- - -## 11. Stellar Testnet TFT Faucet Has No Liquidity - -**Phase:** Testnet account funding -**Issue:** `stellar-utils faucet --secret ` failed with a path payment error. The DEX path swap (XLM → TFT) found no matching orders. -**Root cause:** Stellar testnet DEX has zero TFT liquidity. The official ThreeFold testnet TFT issuer (`GA47YZA3PKFUZMPLQ3B5F2E3CJIB57TGGU7SPCQT2WAEYKN766PWIMB3`) doesn't actively maintain testnet DEX orders, so path payment swaps always fail. -**Workaround:** Create a custom TFT issuer on testnet: - -1. Generate a new Stellar keypair — this becomes the issuer -2. Fund it via friendbot: `https://friendbot.stellar.org/?addr=` -3. Add a trustline from each test account to the custom issuer -4. Send TFT directly from issuer to test accounts (no DEX needed) -5. Patch `TFTTest` constant in `stellar.go` to point to the custom issuer - -**Custom testnet issuer used (test only, not for production):** - -- Address: `GDPARZINMN52LJMVZSQPOEDHC2TWKJVFZSNHKDP4OUH6RI4PMXH4JA6Q` - -> ⚠️ **Important:** Never use a custom issuer in production. Mainnet uses `GBOVQKJYHXRR3DX6NOX2RRYFRCUMSADGDESTDNBDS6CDVLGVESRTAC47`. - ---- - -## 12. Stellar Memo Not Set on Withdraw Transactions (Bug Found During Testing) - -**Phase:** Crash recovery testing -**Issue:** Crash recovery relies on `FindPaymentByMemo` to check if a Stellar withdrawal was already submitted before the bridge crashed. During testing, the reconciliation consistently returned "no Stellar tx found" even when the Stellar tx WAS submitted. -**Root cause:** `CreatePaymentWithSignaturesAndSubmit` submitted Stellar transactions without setting a memo field. `FindPaymentByMemo` searches for `memo_type=text` but found nothing, because withdrawals went out with no memo at all. - -Additionally, when the memo was added only to the submission function and not the signing function (`CreatePaymentAndReturnSignature`), the signature verification failed — because the Stellar tx hash is computed over all transaction fields including memo. Validators signed a hash without the memo; submission with memo produced a different hash; signatures were invalid. - -**Fix:** Added `txnBuild.Memo = txnbuild.MemoText(fmt.Sprint(txID))` to **both** `CreatePaymentAndReturnSignature` and `CreatePaymentWithSignaturesAndSubmit`. The memo must be set at signing time and submission time to maintain hash consistency across all validators. - -**Verification:** After fix, all Stellar withdraw transactions have `memo_type=text` with the burn tx ID as value. Confirmed via Horizon API. - ---- From fd840c361808e1c581dc688a45795c0567b3cf0b Mon Sep 17 00:00:00 2001 From: Sameh Farouk Date: Sat, 7 Mar 2026 04:32:57 +0000 Subject: [PATCH 08/49] fix(bridge): filter to outgoing-only txs in crash recovery Horizon lookup FindPaymentByMemo and FindRefundByReturnHash previously scanned the 200 most recent transactions on the bridge account (incoming + outgoing mixed).

charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes from code review: - stellar.go: refactor lookups into page-based helpers (FindPaymentByMemoInPage, FindRefundByReturnHashInPage, FindPaymentBySequenceInPage) backed by a single FetchOutgoingTransactionsPage call — eliminates redundant Horizon HTTP calls when multiple lookups are needed for the same PROCESSING tx - bridge.go: reconcilePendingTransactions now fetches Horizon once for all pending withdraws and refunds (N+M lookups → 1 HTTP call); skips fetch entirely if no pending transactions - withdraw.go: batch Phase 1 skips individual events on signature creation failure instead of aborting the whole batch; other events in the same block still proposed - withdraw.go: batch Phase 3 only logs withdraw_proposed for proposals that did not fail; uses FailedIndexes for precise tracking on BatchInterrupted runtimes, flags batch_had_failures on ItemFailed runtimes where index is not available - idempotency.go: add comment on store growth (negligible at bridge tx volumes) All changes build clean, vet clean, gofmt clean.

All online validators detect bad deposits via their own Stellar cursor and call proposeRefundDirect before this event fires. Added comment explaining why and what would need to change if catch-up mode is ever needed. - Add Makefile targets for full local bridge dev environment (bridge-dev, bridge-build, bridge-accounts, bridge-tfchain-start, bridge-setup, bridge-start, bridge-test, bridge-clean, bridge-stop). TFChain binary is built once and cached (make dependency on binary file). bridge-dev is a true zero-to-green target. - Add scripts/bridge_accounts.js: generates Stellar keypairs, funds via Friendbot, creates TFT trustlines, issues TFT to bridge (path_payment_strict_send to avoid triggering deposit monitor) and user. Writes /tmp/bridge_local_env.sh. - Add scripts/bridge_setup.js: configures TFChain bridge pallet via sudo — registers validator, sets bridge wallet address, fee account, deposit/withdraw fees. - Add scripts/bridge_tests.js: 4-scenario E2E suite (normal withdraw, batch 5, bad deposit refund, crash recovery). Exits non-zero on any failure. - Add scripts/wait_for_node.js: polls WS endpoint until TFChain is ready, used by bridge-tfchain-start to block until node accepts connections. - Add @stellar/stellar-sdk to scripts/package.json dependencies. --- Makefile | 140 ++++++++ bridge/tfchain_bridge/pkg/bridge/bridge.go | 4 +- bridge/tfchain_bridge/pkg/bridge/withdraw.go | 25 +- scripts/bridge_accounts.js | 197 ++++++++++ scripts/bridge_setup.js | 146 ++++++++ scripts/bridge_tests.js | 360 +++++++++++++++++++ scripts/package.json | 1 + scripts/wait_for_node.js | 55 +++ 8 files changed, 915 insertions(+), 13 deletions(-) create mode 100644 scripts/bridge_accounts.js create mode 100644 scripts/bridge_setup.js create mode 100644 scripts/bridge_tests.js create mode 100644 scripts/wait_for_node.js diff --git a/Makefile b/Makefile index cc94da7cf..702ad8c21 100644 --- a/Makefile +++ b/Makefile @@ -1,3 +1,143 @@ +# ───────────────────────────────────────────────────────────────────────────── +# Bridge local development environment +# ───────────────────────────────────────────────────────────────────────────── +# +# Quick start (first run builds TFChain — takes 20-40 min): +# make bridge-dev +# +# Subsequent runs (TFChain already built): +# make bridge-dev +# +# Run tests against an already-running environment: +# make bridge-test +# +# Configurable via environment variables: +# TFCHAIN_URL WebSocket URL for TFChain node (default: ws://localhost:9944) +# BRIDGE_TFT_FLOAT TFT to mint into bridge wallet (default: 20000) +# USER_TFT_AMOUNT TFT to mint into test user wallet (default: 1000) +# DEPOSIT_FEE Deposit fee in base units (default: 10000000 = 1 TFT) +# WITHDRAW_FEE Withdraw fee in base units (default: 10000000 = 1 TFT) +# BRIDGE_ENV_FILE Env file path (default: /tmp/bridge_local_env.sh) + +# Paths (relative to repo root) +BRIDGE_DIR := bridge/tfchain_bridge +BRIDGE_BIN := $(BRIDGE_DIR)/tfchain_bridge_local +TFCHAIN_BIN := substrate-node/target/release/tfchain +SCRIPTS_DIR := scripts +BRIDGE_LOG := /tmp/bridge_local.log +BRIDGE_PID_FILE := /tmp/bridge_local.pid +TFCHAIN_LOG := /tmp/tfchain_local.log +BRIDGE_ENV_FILE ?= /tmp/bridge_local_env.sh +TFCHAIN_URL ?= ws://localhost:9944 + +.PHONY: bridge-build bridge-build-tfchain bridge-accounts bridge-tfchain-start \ + bridge-tfchain-stop bridge-setup bridge-start bridge-stop bridge-test \ + bridge-dev bridge-clean bridge-help + +## bridge-help: Show bridge dev environment targets +bridge-help: + @grep -E '^## bridge-' $(MAKEFILE_LIST) | sed 's/## / make /' + +## bridge-build: Build the bridge binary (Go, fast ~5s) +bridge-build: + @echo "==> Building bridge..." + cd $(BRIDGE_DIR) && go build -o tfchain_bridge_local . + @echo "==> Bridge binary: $(BRIDGE_BIN)" + +## bridge-build-tfchain: Build TFChain node (Rust, slow first-time ~30min) +bridge-build-tfchain: + @echo "==> Building TFChain node (this may take 20-40 minutes on first run)..." + cd substrate-node && cargo build --release + @echo "==> TFChain binary: $(TFCHAIN_BIN)" + +## bridge-accounts: Generate Stellar accounts and write env file +bridge-accounts: + @echo "==> Installing npm dependencies..." + cd $(SCRIPTS_DIR) && npm install --silent + @echo "==> Generating Stellar accounts..." + BRIDGE_ENV_FILE=$(BRIDGE_ENV_FILE) node $(SCRIPTS_DIR)/bridge_accounts.js + +## bridge-tfchain-start: Start TFChain dev node and wait until ready +bridge-tfchain-start: + @test -f $(TFCHAIN_BIN) || (echo "ERROR: TFChain binary not found at $(TFCHAIN_BIN).

Writes /tmp/bridge_mv_env.sh. - Add scripts/bridge_mv_setup.js: creates twins for all 3 validators (Alice, Bob, Charlie), registers all 3 on TFChain bridge pallet via sudo, sets bridge wallet, fee account, deposit and withdraw fees. - Add scripts/bridge_mv_tests.js: 5-scenario MV test suite: MV1 normal withdraw (3 validators, threshold=2), MV2 deposit/mint (all 3 propose, threshold met), MV3 bad deposit (full refund, 3 validators), MV4 validator offline (Val3 killed, Val1+Val2 meet threshold=2), MV5 batch withdraws (3 simultaneous, handles expiry recovery). Exits non-zero on any failure. Val3 restarted after MV4 for subsequent tests. - Add Makefile targets: bridge-mv-accounts, bridge-mv-setup, bridge-mv-start (3 daemons), bridge-mv-stop, bridge-mv-test, bridge-mv-clean, bridge-mv-dev (full one-shot MV environment).

If not found: log `"no Stellar tx found by memo or sequence, safe to retry"` — re-submit on + next Ready event --- ## Known Limitations -1. **Single-validator dev setup**: The `--dev` genesis seeds only one bridge validator. The bridge immediately reaches threshold on any proposal. Multi-validator quorum behavior is not tested locally. - -2. **Stellar testnet liquidity**: `stellar-utils faucet` is broken on testnet (empty DEX order book). Requires custom issuer workaround (see issue #11 above). +1. **Sequence coordination under load**: All validators sign Stellar transactions at proposal time + with a fixed sequence number. If another Stellar transaction from the bridge account is + submitted between proposal and `Ready` events, the stored signatures reference a stale + sequence → all validators get `tx_bad_seq` on first attempt. Recovery is automatic via the + expiry cycle (~20 blocks, ~2 min delay). This is a pre-existing design constraint, not + introduced by this PR. -3. **Crash recovery window**: The exact scenario of crash-after-Stellar-submit-before-TFChain-confirm - is difficult to trigger in automation due to the sub-second window. The code is correct and - tested for correctness; the timing scenario is documented as a known limitation of the - automated test suite. +2. **Stellar testnet Friendbot rate limits**: If Friendbot rejects account funding (rate limited + or account already exists with funds), re-running `make bridge-accounts` generates fresh + keypairs. This requires re-running `make bridge-setup` and `make bridge-start` as well — + or simply re-run `make bridge-dev` for a clean slate. -4. **`--tmp` chain**: The `--tmp` flag means chain state is lost on restart. For persistence across sessions, use `--base-path /tmp/tfchain-data` instead. +3. **`--tmp` chain**: State is lost on TFChain restart. For persistent sessions, replace + `--tmp` with `--base-path /tmp/tfchain-data` in the `bridge-tfchain-start` Makefile target. From 0e4136ed5f8f4586ab1428dd6a1917920d816b7c Mon Sep 17 00:00:00 2001 From: Sameh Farouk Date: Sun, 8 Mar 2026 21:05:21 +0000 Subject: [PATCH 25/49] fix(bridge): fix make bridge-dev flow after testing on real chain MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Discovered by running make bridge-dev end-to-end: - bridge_setup.js: rewrote as verification-only; dev chain genesis already pre-configures Bob+Charlie as validators, Ferdie as fee account, 1 TFT fees. No sudo pallet on TFChain, no setBridgeAddress call exists on the pallet. Setup script now just prints and verifies genesis config. - bridge_mv_setup.js: same — verification only, no pallet writes. - Makefile bridge-start: fix TFChain seed from //Alice to //Bob. Alice is not a genesis validator; Bob and Charlie are. - bridge_mv_accounts.js: reduce from 3 to 2 validators (val1=Bob, val2=Charlie). The 3rd genesis validator has an unknown seed so cannot run a daemon for it. Multi-sig configured as 2-of-2 (both Bob and Charlie must sign Stellar txs). - bridge_mv_tests.js: update for 2 validators (Bob + Charlie). Redesign MV4 from 'one validator permanently offline' to 'validator restarts mid-flow': kill Val2 after Val1 proposes, restart Val2, verify late-join completes the refund. Removes reference to non-existent Val3 daemon. - bridge_mv_start: fix for 2 daemons with explicit //Bob and //Charlie seeds instead of a loop over 3 with an Alice seed. --- Makefile | 34 ++++---- scripts/bridge_mv_accounts.js | 104 +++++++++--------------- scripts/bridge_mv_setup.js | 147 +++++++--------------------------- scripts/bridge_mv_tests.js | 60 ++++++++------ scripts/bridge_setup.js | 147 ++++++++++------------------------ 5 files changed, 165 insertions(+), 327 deletions(-) diff --git a/Makefile b/Makefile index 584935e81..4d7b1a984 100644 --- a/Makefile +++ b/Makefile @@ -87,7 +87,7 @@ bridge-start: nohup $(BRIDGE_BIN) \ --secret "$$BRIDGE_SECRET" \ --tfchainurl $(TFCHAIN_URL) \ - --tfchainseed "//Alice" \ + --tfchainseed "//Bob" \ --bridgewallet "$$BRIDGE_ADDRESS" \ --persistency $(BRIDGE_DIR)/signer_local.json \ --network testnet \ @@ -157,30 +157,34 @@ bridge-mv-start: @test -f $(BRIDGE_MV_ENV_FILE) || (echo "ERROR: $(BRIDGE_MV_ENV_FILE) not found.

This caused waitForBridgeReady to always timeout in test4 crash recovery. Fix: use 'exec' inside a shell command with append redirect (>>). The shell sets up the redirect before exec, then exec replaces sh with the bridge binary (preserving the same PID).

Changes: - bridge_helpers.js: add tfchainBalance() helper for TFChain balance queries - bridge_tests.js: harden T1-T4 with ExecutedBurn/ExecutedRefund/TFChain balance assertions; add T5 (deposit/mint), T6 (below-minimum reject), T7 (clean state — no orphaned active transactions) - bridge_mv_tests.js: harden MV1-MV5 with ExecutedBurn/ExecutedRefund/ TFChain balance assertions; add MV6 (crash recovery — kill Val2 mid-withdraw), MV7 (clean state) Previously all tests only verified Stellar balance deltas. Now every test also confirms on-chain bookkeeping (executed maps populated, active maps drained) and TFChain balance changes where applicable.

TFChain balance assertions: use >= instead of exact match. - Withdraws: substrate extrinsic fee (~0.003 TFT) causes balance to decrease by slightly more than the swap amount. - Deposits: Alice earns block author rewards on the dev chain, so her balance increases by slightly more than the minted amount. 2. assertBurnExecuted: poll with waitUntil (30s) instead of one-shot check. set_burn_transaction_executed may finalize a few blocks after the Stellar payment is visible to the test. 3. assertRefundExecuted: same polling fix. set_refund_transaction_executed finalizes after the Stellar refund payment.

With no local state, the PROCESSING guard is gone — only protection is IsBurnedAlready (queries ExecutedBurnTransactions on-chain). Verifies Stellar balance stays unchanged (no double-spend), then runs a fresh withdraw to prove the bridge is still functional. T9/MV9 — Expired batch recovery (50 swaps offline → expiry → restart): Kill bridge, submit 50 swapToStellar in one block, wait for on_finalize to expire all 50 (RetryInterval=20 blocks ≈ 120s). Restart bridge — it catches BurnTransactionExpired events and re-proposes all 50 in a single force_batch tx via handleProposalsBatch. Due to Stellar sequence number constraints, ~1 burn succeeds per expiry cycle (~120s). Progress logged as burns complete. 2-hour timeout accommodates the ~100min worst case.

All 50 burns get unique sequences (101..150), so handleWithdrawReady can submit all 50 to Stellar in one pass without sequence collisions. Previous analysis of "~1 burn per expiry cycle" was wrong — that would only apply if all burns shared the same sequence number. Reduced timeout from 2h to 10min. Updated comments to document the actual flow: single force_batch re-proposal → all become Ready → sequential Stellar submissions → individual SetWithdrawExecuted calls (the latter could be batched in a future optimization).

This confirms all burns/refunds in one block (~6s) instead of N blocks (~13s each). Key changes: - handleWithdrawReady returns (uint64, error) — defers TFChain confirmation - handleRefundReady returns (string, error) — defers TFChain confirmation - bridge.go collects IDs, caps at 100 per type, batches TFChain calls - BatchSetWithdrawExecuted/BatchSetRefundTransactionExecuted with fallback to individual RetrySet* calls on batch failure Safety: set_*_executed is idempotent (first-writer-wins). Multi-validator races produce harmless ItemFailed events. Crash recovery unchanged — BoltDB PROCESSING + Stellar memo search on shared bridge account prevents double-spend.
