CLI automation notes (taler-wallet-cli + monitoring)
Living list of recurring issues seen while driving GOA (hacktivism) and
stage TESTPAYSAN via CLI (taler-wallet-cli, bank/merchant HTTP, monitoring
e2e/ladder). Ordered roughly by how often they hurt automation and how
useful a fix in wallet-cli / wallet-core (or clearer APIs) would be.
Companions:
Scripts: check_e2e.sh, check_amount_ladder.sh, taler-monitoring.sh.

1. run-until-done is unusable for automation
|
|
| Seen |
e2e, ladder, Android notes, macOS comments: hangs / banned in monitoring |
| Area |
cli / core |
| Problem |
taler-wallet-cli run-until-done (or long shepherd runs) often never returns or blocks CI-length timeouts. Monitoring forbids it and polls balance + bank transfer_done instead. |
| Workaround |
advanced serve + socket (WSOCK) or pure poll loops (LADDER_SETTLE_*, e2e settle wait). |
| Wanted for wallet-cli |
Bounded wait: e.g. `run-until-done --timeout=Ns --exit-on=withdrawn |
2. Withdraw completion is not observable from CLI alone
|
|
| Seen |
e2e “coins missing after withdraw”; ladder OK_BANK vs wallet avail |
| Area |
cli / core / bank |
| Problem |
After accept-uri + bank confirm, coins may lag (wirewatch). CLI has no single “withdraw settled” command with clear success/failure; automation reimplements status from bank integration JSON + balance polls. |
| Workaround |
Poll balance + …/withdrawal-operation/{id} (status, transfer_done, selected_reserve_pub). |
| Wanted |
wallet-cli withdrawals wait --id=… --timeout= or JSON event stream: selected → confirmed → coins-available. |
3. reserve_pub / force-select is fragile (5114 + empty scrape)
|
|
| Seen |
ladder force-select, e2e confirm path, Android spinner issues; repro 2026-07-19 magikoopa GOA ladder: force-select skipped · no reserve_pub for this withdraw (WID=…); wallet may not have selected yet |
| Area |
cli / core / bank / ops |
| Problem |
(a) Cumulative wallets re-emit old reserves; binding the wrong reserve_pub yields HTTP 409 / code 5114 (“already bound”). (b) Automation scrapes accept/tx dumps for candidates — when the dump has no pub at all, ladder WARNs and skips force-select (soft), then often SKIP_CONFIRM. (c) Empty scrape is not the same as “bank out of money”; do not treat as balance failure. (d) Mon bug (fixed v1.20.2): extract used json.loads(file_from_first_brace) on wallet dumps that append log lines after JSON → zero objects parsed; regex only scanned accept (which has no reservePub) while the pub lives under transactions[].withdrawalDetails.reservePub. |
| Workaround |
Mon ≥1.20.2: JSONDecoder.raw_decode + regex on accept and transactions; score by WID in bankConfirmationUrl / amount. Still: score pubs by WID/amount; try several; treat 5114 as “stale reserve” not “out of money”. Refresh transactions before each force-select try. Soft-skip confirm if still pending after polls. Fix wallet DB / helper first if accept/tx only print FATAL (see §15–16). |
| Wanted |
CLI returns the reserve_pub for the just-accepted withdraw in structured JSON; force-select / bank-side select API documented with idempotency. Optional: bank integration already exposes selected_reserve_pub when wallet selected — prefer that over scraping wallet logs. |
3a. Ladder pin amounts hide mid-range behaviour
|
|
| Seen |
LADDER_STEPS=3 plan collapses to pins only: GOA:0, max-1, max (no random mid rungs) |
| Area |
ops / bank / cli |
| Problem |
Zero withdraw often never produces a usable reserve_pub / coins (wallet 7006 or no denoms). Absolute max and sometimes max-1 hit mint HTTP 500 / code 5110 SQL P0001 (ceiling probe). Reproducing “real” force-select needs a mid amount (e.g. GOA:1 … exchange min denom scale), not only pins. |
| Workaround |
Use LADDER_STEPS≥5 (or higher) so random mids exist; treat zero / absolute-max / max-1-5110 as probes (soft CEILING_REJECT in mon ≥1.20.2). |
| Wanted |
Ladder plan docs: pin vs mid semantics; CLI structured error for amount-too-large / zero. |
3b. We do not manage to withdraw in time (GOA) — bank path unreliable, not load
|
|
| Bottom line |
On live hacktivism GOA, automation does not get spendable coins in time for the pay phase (default wait 90 s). Max-search may report a “best” amount and bank may even show transfer_done; pay still sees available=GOA:0 with large pendingIncoming. Coins might arrive later (wirewatch / wallet) — at least not within mon’s budget. Recurring (several runs, 2026-07-19). |
| Area |
bank + wire/wallet settle — not mon overload, not “laptop too slow” |
| Not the cause: ecosystem load |
Outside-in check 2026-07-19 ~14:56 CEST: bank/exchange/merchant all HTTP 200, config ~50–150 ms, exchange /keys ~0.5 s. Container loadavg ~1.5–1.7, RSS bank ~737 MiB / exchange ~670 MiB, bank probes 47 ms, wirewatch_running: true. Stack is healthy under moderate load — failures are application/SQL/protocol, not “host on fire.” |
| Call site (mint) |
POST ${BANK}/accounts/explorer/withdrawals → often HTTP 500 { code: 5110, hint: "Unexpected sql error with state P0001" } (BANK_UNMANAGED_EXCEPTION; Postgres P0001 = RAISE EXCEPTION). Should often be clean 409 (insufficient funds); instead opaque 500. |
| Config |
/config still allows ~2⁵² wire max; live mint fails far below that. Explorer balance_explorer on landing still ~4.5 Peta-GOA. |
Analysis — where withdraw dies
| Stage |
What we see |
Manage to withdraw? |
| Mint (high amounts) |
5110/P0001 while hi falls Tera→Giga→Mega→Kilo with lo=0 |
No — withdrawal never created |
| Mint (some mid amounts) |
occasional HTTP 200 + URI |
Mint only — not done |
| Confirm |
force-select 200 then stuck selected, confirm HTTP 500 → mon SKIP_CONFIRM (bounds unchanged) |
No — bank never wires; not out-of-money (§3 / 5114 class) |
| Bank settle |
rare full path: confirm 204 + transfer_done |
Bank side “OK_BANK” |
| Wallet coins |
almost always available=0 within wait, large pendingIncoming, board done=0 |
Not in time for pay → SKIP_BALANCE / skip max-pay |
Pay-wait board (same cumulative wallet), example:
summary: tsv_ok=2 · wallet_wd=14 (pendingIncoming=14 done=0)
timer 0s left — available still GOA:0
pendingIncoming=GOA:335776
Reading: only 2 TSV rows are full OK/OK_BANK, but the wallet holds 14 withdrawal txs still pendingIncoming and none done after the wait. Max-search also leaves many mint-OK / confirm-failed withdraws that inflate pendingIncoming and may never complete. After 90 s + short run-pending: still no spendable balance → we do not manage to withdraw in time for pay (whether coins would appear later is unknown to the job).
What did work (sparse) — for contrast
| When / run |
What worked |
Amounts |
| Landing 2026-07-19 14:19–14:29 CEST |
Explorer singles recorded on bank intro stats |
~1.5–2 Giga-GOA, ~145–202 Mega-GOA, ~1.8–3.4 Mega-GOA |
| Max-search run A (same day) |
Full bank path (mint→confirm→transfer_done) for two amounts only; mon best |
GOA:424114, GOA:822256 (~822 Kilo best) |
| Max-search run B (later) |
Even fewer full successes; many mint OK + SKIP_CONFIRM; mon best collapsed |
e.g. full success around GOA:12276 / GOA:17257 (~17 Kilo best) |
| Pay after either |
Spendable available within 90 s |
GOA:0 (not in time) |
So: landing/history prove large withdraws were possible earlier the same day; automation does not manage a usable withdraw in time (best amount drops run-to-run; coins not available inside mon’s wait).
Mon behaviour (workaround only)
- 5110 → soft
CEILING_REJECT / max-search hi:=
- Full OK only raises
lo; SKIP_CONFIRM does not
- Pay waits up to
LADDER_PAY_WAIT_AVAILABLE_S (default 90) with withdraw board; then SKIP_BALANCE if still 0
- Does not fix bank SQL mapping, stuck confirm, or wirewatch→coins lag
Wanted (bank / exchange ops)
- Map mint P0001 to structured errors (not 5110).
- Confirm after force-select must not stick selected + HTTP 500.
- After
transfer_done, coins must become wallet available (or document delay + API to wait).
- File bugs with: max-search “what worked” table + landing
recent_withdraws/balance_explorer + load note (healthy) + pay board tsv_ok vs wallet_wd/pendingIncoming/done.

4. Exchange not auto-known for bank deep links / withdraw URIs
|
|
| Seen |
Android endless spinner; GOA bank.hacktivism.ch withdraw; fixed in app branch fix/bank-withdraw-auto-exchange |
| Area |
core / cli |
| Problem |
Withdraw URI names an exchange the wallet has never added → stuck loading / empty exchange list. CLI requires explicit exchanges add + update + accept-tos every fresh DB. |
| Workaround |
e2e always adds exchange before bank withdraw ladder; Android needs ensureExchange-style fix. |
| Wanted |
CLI/core: on accept-uri withdraw, auto-add exchange from URI/bank details (allowCompletion), then surface ToS if needed in one command. |
5. Default ports in URIs (:443 / :80) break round-trips
|
|
| Seen |
ladder/e2e strip ports; QR checks; mint URIs with :443 |
| Area |
cli / bank / doc |
| Problem |
Some bank/wallet outputs include taler://…host:443/…. QR validators and some clients reject or double-normalize inconsistently. |
| Workaround |
mon ≥1.23.4: normalize_taler_uri (lib.sh) on ladder/e2e/pay; bank landing demo-withdraw-api.py normalizes mint JSON; urls phase fails GOA/local if public landings still emit :443/:80 in taler:// (www.taler-uri-ports-*, unit tests/test_normalize_taler_uri.sh). |
| Wanted |
libeufin never emits default ports (source fix). |
6. No first-class “demo withdraw” / explorer mint in wallet-cli
|
|
| Seen |
e2e uses bank admin + bank withdraw create; ladder/gui-chain reimplement explorer mint in Python |
| Area |
cli / ops |
| Problem |
Automation always hand-rolls Basic auth → token → POST …/withdrawals → taler_withdraw_uri. Easy to get wrong (auth header, amount currency). |
| Workaround |
Shared Python in goa-chain / ladder / e2e; secrets files. |
| Wanted |
Optional helper: wallet-cli testing mint-withdraw --bank=URL --user=explorer --password-file=… --amount=GOA:10 (or bank-side only tool in libeufin) emitting a clean URI. |
7. Long-lived wallet process required for pay/withdraw progress
|
|
| Seen |
e2e advanced serve / shepherd socket |
| Area |
cli |
| Problem |
One-shot CLI invocations do not keep background work alive; without serve/shepherd, withdraw/pay may stall mid-flight. |
| Workaround |
Start serve once per e2e run; route wcli through the socket. |
| Wanted |
Documented, supported “session mode”: start/stop serve; or each mutating command optionally --background-until=… with timeout. |
8. ToS accept is a separate step that fails silently or blocks
|
|
| Seen |
e2e exchanges accept-tos; ladder after add; Android GUI ToS screens |
| Area |
cli / core |
| Problem |
Fresh exchange → operations need ToS; CLI must call accept-tos explicitly. Failures are easy to miss in multi-step scripts. |
| Workaround |
Always accept-tos after update in e2e/ladder. |
| Wanted |
accept-uri --accept-tos or auto-prompt with non-interactive --yes that covers exchange ToS for that URI’s exchange. |
9. Pay template / public order path is merchant-shaped, not CLI-shaped
|
|
| Seen |
e2e shop templates, stage farmer shops, ladder private orders |
| Area |
cli / doc |
| Problem |
Wallet-cli pays via handle-uri on taler://pay/…; creating the order is always custom curl (template POST or private order + token). No unified “pay this amount to instance” for public templates. |
| Workaround |
Monitoring builds URI externally then handle-uri --yes. |
| Wanted |
Documented recipe only, or wallet-cli testing pay-template --base=… --instance=… --id=… for demos. |
10. Amount / currency parsing edge cases
|
|
| Seen |
ladder min denom 0.01 vs GOA 1e-6; zero withdraw rejected (HTTP 409 / amount too low); max wire ceilings |
| Area |
cli / bank |
| Problem |
CURRENCY:0 and sub-min amounts fail differently per stack; CLI error strings are not machine-stable. |
| Workaround |
Soft-skip zero rung; clamp ladder min to exchange denoms / bank max_wire. |
| Wanted |
Structured errors (AMOUNT_too_small, currency_unknown) in JSON mode; wallet-cli amount validate --exchange=. |
11. Finding the right taler-wallet-cli binary
|
|
| Seen |
find_wallet_cli in lib.sh; hardcoded laptop paths; wrapper vs .mjs |
| Area |
ops / cli |
| Problem |
Debian package is a shell wrapper; some tools need node …/taler-wallet-cli.mjs. Hardcoded /Users/… paths break other hosts. |
| Workaround |
find_wallet_cli search list; WALLET_CLI= override. |
| Wanted |
Single install story: wallet-cli --version JSON with path + libversion; no need to pass .mjs to node by hand. |
12. Secrets and multi-stack confusion
|
|
| Seen |
explorer vs admin password; GOA secrets used on stage; ladder EXP_PW |
| Area |
ops |
| Problem |
CLI does not know “which stack”; wrong password → 401 mid-ladder. Not a wallet-cli bug, but every CLI automation hits it. |
| Workaround |
SECRETS_ROOT, stage SSH, STACK= profiles. |
| Wanted |
Optional ~/.config/taler/stacks.d/goa.env convention documented next to wallet-cli; still no secrets in repo. |
13. No stable machine-readable “step result” for scripts
|
|
| Seen |
e2e greps accept output; ladder scrapes JSON from mixed stdout |
| Area |
cli |
| Problem |
Human logs + occasional JSON blobs; hard to parse reliably. |
| Workaround |
Python scrapers, temp files, tee. |
| Wanted |
Global --json / --ndjson for all commands; one object per completed operation with ok, op, ids, amounts. |
14. Pay settlement wait is symmetric to withdraw pain
|
|
| Seen |
e2e pay settle loops; ladder pay settle rounds |
| Area |
cli / core |
| Problem |
After handle-uri pay, success is “order paid” / balance drop / merchant order status — not one CLI wait. |
| Workaround |
Short poll loops; never run-until-done. |
| Wanted |
Same as §1–2: bounded wait on transaction id / order id. |
15. --wallet-db=*.json is rejected (“memory backend not supported”)
|
|
| Seen |
2026-07-19 magikoopa wallet-cli 1.6.8 / 1.6.11 bundle: any command with --wallet-db=/tmp/foo.json fails immediately with Error: memory backend not supported |
| Area |
cli / ops |
| Problem |
Current node host treats storage paths ending in .json as unsupported memory backend and throws before opening sqlite. Old notes / local tests that used WALLET_DB=….json break. Accept/transactions then never emit reserve_pub → ladder §3 empty-scrape WARNs. |
| Workaround |
Use a non-.json path, e.g. --wallet-db=$SCRATCH/wallet.sqlite3 (ladder already prefers wallet.sqlite3). Never pass ….json as wallet-db. |
| Wanted |
Clearer error: wallet-db path must not end in .json; use a directory or .sqlite3 path. Document legal path forms in --help. |
16. taler-helper-sqlite3 requires Python ≥ 3.11 on PATH
|
|
| Seen |
magikoopa: helper is a Python script (#!/usr/bin/env python3); with Apple /usr/bin/python3 3.9.6 → FATAL: python version >=3.11 required but running on 3.9.6 in accept/tx logs; wallet may still exit 0 on some paths while stdout is FATAL-only |
| Area |
ops / cli |
| Problem |
Wallet spawns taler-helper-sqlite3 from PATH. Wrong python3 ⇒ sqlite backend fails ⇒ no real wallet state ⇒ no reserve_pub for force-select. |
| Workaround |
Put Python ≥3.11 (or 3.12+) first on PATH for mon jobs; ensure command -v taler-helper-sqlite3 works; smoke: taler-helper-sqlite3 starts without FATAL. Prefer Homebrew / user python3.11+ over macOS system 3.9 for agent PATH. |
| Wanted |
Helper shebang or wrapper that finds a suitable python; wallet preflight error if helper HELLO fails (not silent empty logs). |
17. Portable wall-clock for scripts (no GNU timeout assumed)
|
|
| Seen |
macOS agent shells: timeout: command not found; e2e already tries timeout then gtimeout then perl -e alarm |
| Area |
ops / doc |
| Problem |
GNU coreutils timeout is not on stock macOS. Hard-wiring it breaks portable repro and CI on Darwin. |
| Workaround |
Prefer python3 subprocess.Popen(…).wait(timeout=…) for outer budgets; for wallet-cli inner calls keep e2e order: timeout → gtimeout → perl alarm. Document both. |
| Wanted |
One suite helper run_with_budget SECS cmd… in lib.sh used by ladder/e2e/smoke. |
18. How to withdraw (operator checklist, GOA laptop)
Portable path that works when §§15–16 are fixed:
- PATH:
taler-helper-sqlite3 + python3 ≥ 3.11 ahead of system 3.9.
- Wallet DB:
WDB=$TMP/wallet.sqlite3 — not *.json.
- Exchange:
exchanges add → update -f → accept-tos for https://exchange.hacktivism.ch/.
- Bank mint (explorer): token with explorer password from
SECRETS_ROOT / EXP_PW; POST …/accounts/explorer/withdrawals with e.g. {"amount":"GOA:1"} (avoid pure 0 and absolute max pins for happy-path tests).
- Strip
:443 from taler_withdraw_uri.
withdraw accept-uri --exchange URL URI.
- Bank: poll
…/taler-integration/withdrawal-operation/{WID} → when selected, confirm; if stuck pending, force-select with scraped reserve_pub (§3).
- Settle: poll wallet balance / bank
transfer_done — no run-until-done (§1).
If step 6’s stdout is only FATAL: python version… or memory backend not supported, stop and fix §15–16 before debugging force-select.
Priority shortlist for taler-wallet-cli / core
If only a few changes land, these unlock the most automation:
- Bounded
run-until-done / wait-for-state (§1, §2, §14)
- Structured JSON on every command (§13)
- Auto-add exchange + ToS on accept-uri (§4, §8)
- Canonical URIs without :443 (§5)
- Emit reserve_pub for last withdraw (§3)
- Clear wallet-db path rules + helper preflight (§15, §16)
How we work around today (monitoring)
| Issue |
Monitoring behaviour |
| run-until-done |
Disabled; balance + bank poll |
| serve |
Optional long-lived socket in e2e |
| exchange |
Explicit add/update/accept-tos |
| ladder explorer |
read_secret / EXP_PW_FILE |
| stage maxima |
bank max_wire + keys min denom |
| force-select |
multi-rpub try; soft-skip confirm; empty scrape → WARN not balance fail |
| higher amounts / withdraw fail |
§3b: we do not manage to withdraw in time on GOA (healthy load); mint 5110/P0001 + SKIP_CONFIRM + pendingIncoming; pay still available=0 after 90s; landing had Giga/Mega earlier same day |
| pay vs balance |
never order more than wallet available (soft SKIP_BALANCE); pendingIncoming does not count as spendable |
| pay wait UX |
board: OK/OK_BANK start order + live pendingIncoming/done; often tsv_ok≪wallet_wd and done=0 after 90s → skip pay |
| wallet-db path |
Prefer *.sqlite3 (never *.json as db path) |
| helper / python |
mon PATH must include helper + python≥3.11 |
