script/lint ran `prettier --check .`, byte for byte what script/fmt-check
runs, so make check checked formatting twice and did no static analysis on
a cryptocurrency wallet. Two used-but-not-imported crashes shipped past it.
ESLint is pinned in package.json with @eslint/js recommended as the base and
a flat config in eslint.config.js. no-undef and no-unused-vars are restated
error-level so a future recommended-set change cannot downgrade them.
Globals are declared per tree rather than globally, because a too-wide set
hides the next unimported identifier: browser for the popup and content
scripts, service worker for src/background/ and src/shared/, browser for the
one documented POPUP ONLY module in src/shared/, jest for tests/, node for
build.js, and both for the e2e harnesses, which carry the callbacks they
ship into the page inline.
Two rules new to the recommended set are off, and both would have cost
something to satisfy. no-useless-assignment flags the `password = null` and
`decryptedSecret = null` wipes in approval.js and confirmTx.js: those
assignments are dead by construction, which is the point of them, and the
rule's fix is to delete the wipe. preserve-caught-error would change what
the wallet's error paths throw, which is a decision of its own.
Every remaining violation is fixed: 41 unused bindings and 53 undefined
identifiers. Unused catch bindings became `catch {`, which the repo already
used; the shared init(ctx) view signature keeps its parameter as _ctx in the
three views that do not read it. src/shared/uniswap.js keeps its unused
V2_SWAP_EXACT_OUT decoder behind a scoped disable, because deleting it would
widen the gap it represents rather than close it (#283).
Linting is containerized. script/lint builds the Dockerfile's new lint stage
so the ESLint deciding whether this repo is green is the pinned one and not
whatever the host has; AUTISTMASK_LINT_NATIVE, set only in that image, is
what makes make check inside the CI build lint in place instead of recursing
into docker. The check stage takes a COPY --from=lint dependency so a lint
failure fails the whole build early rather than racing it.
No --fix anywhere in the lint path: make check remains non-mutating.
The README claim that a used-but-not-imported identifier is invisible to
make check, and the same claim in script/test-e2e, are no longer true and
are corrected.
The provider rebuilt every rejection as a bare Error carrying only a message,
so a dApp checking err.code === 4001 saw undefined and could not tell a user's
deliberate refusal from a failure. Well-behaved sites therefore showed an error
or retried instead of accepting the refusal. The code was produced correctly
and did cross the extension boundary; it was lost in the last hop.
Rejections now reach the page as a ProviderRpcError carrying code, and data
where present. The code is passed through verbatim rather than matched against
a whitelist, so a code added upstream later needs no change here. An error that
genuinely has no code stays a plain Error with no code property at all, rather
than advertising code: undefined -- 'code' in err is what a careful dApp asks.
Messages are unchanged for every path, verified byte-for-byte against the
previous provider across every background error shape.
The end-to-end assertion that printed the observed code now requires it.
The dApp signing path was the largest unverified surface in the milestone: the
only place where the content script, the inpage provider, the background worker
and the popup all have to work together, with unit tests covering each side in
isolation and none covering the seam.
A page served by the harness speaks EIP-1193 to the real provider -- asserted by
EIP-6963 object identity, not by shape -- and eth_requestAccounts, personal_sign,
eth_signTypedData_v4 and eth_sendTransaction are each driven through to approval
and to rejection.
Every signature is recovered and compared to the approved address; the broadcast
transaction is parsed from the bytes captured at eth_sendRawTransaction and
checked for signer, recipient, value, calldata and chain. A signature that
merely came back would pass against a wrong key, a wrong message or a wrong
chain, so each assertion was demonstrated failing against a variant that is
wrong in exactly one of those ways.
The password is asserted absent from every message crossing the extension
boundary, which gives #157's fix a permanent floor rather than a one-time
review.
Two defects this surfaced are tracked separately: EIP-1193 error codes never
reach the page (#274), and approving a site connection races the popup teardown
(#275). Neither is asserted as correct here. A real dApp with real funds against
mainnet remains an uncovered human pass and is documented as such.
ConfirmTx -- the screen that decides what gets signed -- had no automated
coverage of its own behaviour. The arithmetic underneath was well tested; the
wiring was not, so a mutant making the spend gate read the displayed fee
estimate instead of the reserve would have reintroduced the #154 overspend with
the suite still green.
Nine end-to-end tests now drive it for both the native and ERC-20 paths,
covering the pending, funded, over-balance and estimate-failed states, and
asserting that the gate reads the reserve rather than the estimate. Swapping the
two makes the suite fail. The view height is asserted constant across every
state transition rather than merely printed.
Reaching the screen needs a funded balance and a gas estimate, so the route
interception gains fixtures for both. Testing the estimate-failed state means
provoking the console error the code is supposed to emit, which the harness
otherwise fails a run on; an expectation mechanism consumes exactly one matching
record, is scoped to the declaring test, and fails that test if nothing matched,
so it cannot mask an unrelated error.
The dust-threshold field was the only validated input in Settings that rejected
without saying anything: the value silently changed back to the stored one with
no explanation. It now flashes "Please enter a whole number of gwei, zero or
greater." alongside the existing resync, matching the idiom the RPC URL field
already uses.
The parse moves to its own module and accepts plain decimal digits only, zero
or greater. Hex and exponent notation are refused rather than accepted: Number()
reads "0x10" as 16 and "1e3" as 1000, neither of which the previous parseInt
produced, and storing a number the user did not type is the same silent
substitution this change exists to remove.
The message must fit one line of the reserved flash area -- a wrapped message
pushes the settings view down, which the No Layout Shift policy forbids. That is
pinned by an end-to-end test measuring the rendered line height and the position
of the elements below it, in a single round trip because the flash clears after
two seconds.
Address rows on Home gain an [x] control, on wallets that derive addresses from
an extended key and hold more than one, opening a DeleteAddress confirmation
screen.
Removal cannot destroy anything: the key material stays. Derivation indices are
not renumbered, so the next "+" derives the next unused index rather than
resurrecting the removed one. The confirmation states the real route back --
delete the whole wallet in Settings, which asks for the password and destroys
the stored recovery phrase, then import it again -- and notes that the scan
which follows only finds addresses with on-chain activity. The copy varies by
wallet type, since an xprv wallet has no recovery phrase.
Removing an address that holds a balance is allowed, with a warning naming no
figure; the funds are at the address on-chain and stay there either way.
Selection and active address move only when the removed address was the one
selected, and site permissions are dropped for it alone.
The state transition shares its address comparison, permission cleanup and
active-changed broadcast with the wallet-level removal.
Runs the real popup in a pinned containerized Chrome and fails on any uncaught
page error or console.error. Also fixes the two defects it caught: the missing
showView import in addToken.js and the missing addressDotHtml import in
transactionDetail.js.
