audit: take deploy logic and network config from upstream - #31
Merged
Merged
Conversation
Follows the repo audit for places that re-derive what `rain-deploy`
already owns. Upstream is the single source of truth; each of these had a
local second spelling of it that could drift.
Prod checks walk `LibRainDeploy.supportedNetworks()`
`LibDecimalFloatDeployProd.t.sol` held its own hardcoded network list, so
a network added upstream was a network the prod check silently skipped.
It now walks the upstream list, asserts the list is non-empty (an empty
one would pass every assertion by never running one), and aggregates
per-network failures instead of aborting on the first, so one run names
every network that is wrong rather than the alphabetically-first.
`reasonOf` decodes the revert payload to text so a CI reader gets
"arbitrum: <reason>" rather than a hex blob, falling back to hex for
anything that is not a 4-byte selector plus an ABI encoded string rather
than reverting inside the handler and losing the other networks with it.
Deterministic deployment goes through the factory
Four sites hand-rolled `create(0, ...)` where `LibRainDeploy.deployZoltu`
already deploys deterministically, three of them then etching the runtime
across to the pinned address by hand. That is what the factory does, and
weaker: an etch writes the runtime wherever it is told, so it keeps
passing when the creation code and the pinned address have diverged. The
factory landing somewhere other than the pin is now a failure.
`test/abstract/LogTest.sol` keeps its raw `create` and says why: it wants
a SECOND copy at an address that is deliberately not the pin, so that
tests taking a log-tables address as an argument can distinguish a passed
argument from the pinned constant. `deployZoltu` cannot serve, because
for this creation code it lands on the pin, which `setUp` has occupied.
Etherscan config carries chain ids
Five `[etherscan]` entries had neither `chain` nor `url`, which is what
`EtherscanEntryUnresolvable("arbitrum")` was reporting. All nine now
carry `chain`. This was misread as a missing CI secret twice before the
config was read.
Generated path is derived, not respelled
`script/Build.sol` spelled `src/generated` for the log tables while every
other write in the file takes it from `recordRoot()`. It was the one path
upstream did not own: it would keep writing to the old place if
`LIB_FS_ROOT` moved, and would ignore a `recordRoot()` override, which
exists so `cutRelease()` can run against a record other than the repo's.
Now `GENERATED_LOG_TABLES_LEAF` is a leaf name joined to `recordRoot()`.
`LibEtchLogTables`'s docstring named `script/Deploy.sol` as a consumer.
It is not one and must not be: a chain without the tables is a chain the
suite must not deploy to. The four real callers are named instead.
`forge test --force`: 42 suites, 75 passed, 3 failed — the 3 are
`testSuitesLiveOnEverySupportedNetwork`,
`testSupportedNetworkChainIdsAreBound` and the prod walk, all failing
only on missing `*_RPC_URL` env vars, which CI supplies. Identical to the
pre-change baseline. `forge fmt --check` and `forge lint -D warnings`
clean.

The prod walk's docstring credited `testSupportedNetworksAreFullyConfigured` for guarding the network config. No such test exists — the name was written into the comment without being checked. The real guard is upstream's `testSupportedNetworkChainIdsAreBound` in `RainDeployVerifyChain`, inherited here through `test/src/abstract/DecimalFloatDeployChain.t.sol`. It forks each network that states a chain id, which is why it is one of the suites that needs `*_RPC_URL` to run. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

- Line 81: Update the `reasonOf` revert-payload handling to validate the ABI
string length and padded data bounds before calling `abi.decode`, or fall back
to `vm.toString(err)` if decoding fails. Ensure malformed payloads return a
reason without aborting the network walk, so later networks are still checked.

…ork name Retracts a7ddd44, which was wrong. That commit claimed `testSupportedNetworksAreFullyConfigured` does not exist and removed the docstring's reference to it. It does exist. It is `RainDeployVerifySnapshot.testSupportedNetworksAreFullyConfigured`, inherited here through `test/src/abstract/DecimalFloatDeploySnapshot.t.sol`. The grep behind that claim searched only this repo's `src` and `test`, not `dependencies/`, so an inherited test read as a missing one. The CI run on this branch is what exposed it: the name appears in main's failure list as `[FAIL: EtherscanEntryUnresolvable("arbitrum")]`. The docstring now names both upstream guards and says which is which: `testSupportedNetworksAreFullyConfigured` reads `foundry.toml` and needs no fork, so it catches a missing `[rpc_endpoints]` or `[etherscan]` entry locally; `testSupportedNetworkChainIdsAreBound` forks and needs `*_RPC_URL`. That first one is the discriminating test for this PR's `[etherscan]` change, and it runs locally: base's foundry.toml -> [FAIL: EtherscanEntryUnresolvable("arbitrum")] this branch's -> [PASS] Separately, CI printed `flare: flare: DecimalFloat not deployed`. The walk prefixes every collected line with the network and `checkProdDeployment` named it again. The prefix stays with the walk, because a cheatcode failure reverts before any assertion and can only be named by the caller, so the assertion messages drop it. `forge test --force`: 42 suites, 75 passed, 3 failed on missing `*_RPC_URL` as before. fmt and lint clean.

CodeRabbit finding on #31, and it is real. `reasonOf` checked the payload length and the offset word, then called `abi.decode(payload, (string))`. A payload can carry offset `0x20` and still declare a string length its data does not cover, and `abi.decode` reverts on that. `reasonOf` runs inside the walk's `catch`, so that revert does not fall back to hex — it propagates out of `testProdDeploymentEverySupportedNetwork` and takes every other network's result with it. That is the exact failure the hex fallback exists to prevent, reintroduced by the fallback's own implementation. The decode now goes through `this.decodeStringExternal`, so a malformed payload is caught rather than predicted. Bounds arithmetic would have to be right about every malformed shape; `try` is right about all of them by construction. The offset check stays. The `try` would catch its revert, but a custom error whose first word happens to be a valid offset could decode into a garbage string instead of falling back, and a shape check is the only thing that rejects that. Three tests, all passing: testReasonOfDecodesRevertString a well formed Error(string) still decodes to its text testReasonOfSurvivesMalformedStringPayload offset 0x20 + length type(uint256).max falls back to hex rather than reverting testMalformedStringPayloadDoesRevertAbiDecode the same payload really does revert abi.decode, so the test above is not vacuous The third exists because the second alone could pass for the wrong reason: if the payload were quietly decodable, the fallback assertion would hold while proving nothing about the `try`. `forge test --force`: 42 suites, 81 tests, 78 passed, 3 failed on missing `*_RPC_URL` as before. fmt and lint clean.

Three findings from a final sweep for remaining upstream duplication. Forks are created before any is selected `checkProdDeployment` called `vm.createSelectFork(network)` inside the walk. `LibRainDeploy.createForks` documents why that is wrong: foundry captures the pre-fork account set when the first fork is SELECTED, and seeds every fork created after that capture with it, so such a fork reads an address the caller already touched as the empty account a bare 31337 EVM has for it. A `createSelectFork` loop creates fork N after the capture for every N past the first. The loop was correct only by accident — nothing in this contract touches the pinned addresses before the first select, so the captured set was empty of them. The accident is one edit deep: the sibling `DecimalFloatDeployChainTest` already has exactly the `setUp` that would break it, etching the tables at the pin. With that, eight of nine networks would report `DecimalFloat not deployed` while naming real addresses on chains that hold them. Now two passes: create every fork, then select and check each. Not `LibRainDeploy.createForks`, which is the same creation in one call but reverts on the first unreachable endpoint and so reports no network after it. Creating them one at a time through an external call keeps an outage attributed to its own network, the way a missing deployment already is. The chain test binds `RainDeployVerify`, not `RainDeployVerifyChain` Upstream calls `RainDeployVerify` "the ONE contract a deploy repo binds" and reserves putting a new check directly on the union: "A new check therefore goes into a contract this already inherits, or into this." This repo bound the two halves separately, whose union is the same set TODAY, so a check added to `RainDeployVerify` itself would never arrive and nothing would say so. `DecimalFloatDeploySnapshotTest` keeps binding `RainDeployVerifySnapshot` alone, so that half is now bound twice. Deliberate: the snapshot group forks nothing, and `--match-contract` selects at a contract boundary, so its own contract is what lets a job with no RPC credentials run it. Four extra network-free tests is cheaper than losing either the credential-free run or a future union-level check. The manual deploy workflow describes the real mechanism Its header credited `script/Deploy.sol`'s "DEPLOYMENT_SUITE switch". That file holds no switch — it is a declaration plus `RainDeployBroadcast`, and upstream's `RainDeployBroadcast.run()` resolves the value through `suiteByName` against the keys `DecimalFloatDeploySuites` declares. Same class of error as the `LibEtchLogTables` docstring earlier in this branch: a comment naming a consumer that is not one. It also now says why the suite keys are hand-listed as `options` — a workflow input cannot read them out of Solidity — and that an unlisted suite cannot be dispatched, which fails visibly rather than deploying the wrong thing. Swept and found nothing: Zoltu factory address and codehash, network names and chain ids, snapshot and lib paths, etch and deployZoltu call sites, broadcast suite dispatch, the `RainDeploySuitesBase` shim (required — the generated libs' relative import is emitted upstream), crates and test_js. `forge test --force`: 42 suites, 85 tests, 82 passed, 3 failed on missing `*_RPC_URL` as before. fmt and lint clean.

`src/generated/LogTables.pointers.sol` -> `src/generated/LogTables.bytes.sol`. There are no pointers in it. It holds five `bytes` constants of log and anti-log table data: LOG_TABLES, LOG_TABLES_SMALL, LOG_TABLES_SMALL_ALT, ANTI_LOG_TABLES, ANTI_LOG_TABLES_SMALL. The name came from the rainlang convention, where a generated file of this shape holds function pointers — `RainlangReferenceExternPointers.sol` has `SUB_PARSER_FUNCTION_POINTERS` and friends. Same generator, `LibCodeGen.bytesConstantString`; the filename followed the generator's usual payload rather than this one's. Nothing enforced it: `rain-sol-codegen` never mentions `.pointers`, and no other `.pointers.sol` exists in any dependency. It had been there since 03edf4f, the initial commit. `.bytes.sol` matches `test/src/lib/table/LibLogTable.bytes.t.sol`, which already tested it under that word, and distinguishes it from `src/generated/candidate/LogTables.sol` — the deploy record of the data contract these bytes are wrapped in, which is a different thing with nearly the same name. Done now because the repo is already cutting a version for the moved `DecimalFloat` address, so a consumer re-pins once rather than twice. The blast radius is smaller than it looks: rainlang vendors this file but never imports its path, reaching the tables through `LibDecimalFloatDeploy`. `Build.sol`'s docstring also claimed the leaf was a name "the deploy pins and importers reference". The deploy pins addresses, not filenames. It now says importers reference it, and records what the old name got wrong. Pure rename: git records `R` with no content change, and re-running `script/Build.sol` regenerates the file byte-identical at the new leaf. `forge test --force`: 42 suites, 85 tests, 82 passed, 3 failed on missing `*_RPC_URL` as before. fmt and lint clean.

Same test, same command, only the config swapped.testProdDeploymentEverySupportedNetwork— replaces 5 hardcoded per-network tests with a walk of upstream's 9. CI on this branch proves the coverage gap was real: it reports all 9 networks in one run, where base's tests could only ever report the 5 they named.bsc,ethereum,hyperevmandrobinhoodhad never been checked. The assertions need*_RPC_URL, so CI is the only place this runs.testCheckLogTablesDeployedSucceedsWhenPresentandtestCheckLogTablesDeployedMutation— pre-existing, and the reason the etch removal is safe rather than assumed: both still pass with the temp-deploy-and-etch replaced bydeployZoltu, so the codehash check is still what they are keyed on.LogTest.setUp's codehash assertion — unchanged, and now backed by a pin assertion insideLibEtchLogTablesthat fires first and names the cause.testReasonOfSurvivesMalformedStringPayload+testMalformedStringPayloadDoesRevertAbiDecode— the pair for CodeRabbit's finding. The first asserts the fallback and reverts against the pre-fixreasonOf, which calledabi.decodedirectly. The second asserts the payload genuinely revertsabi.decode, so the first cannot pass for the wrong reason; it exercises the new helper, so it has no pre-fix form to run against.script/lib/LibEtchLogTables.sol:45→combinedTables()replaced withhex"deadbeef"→ killed bysetUp()in everyLogTestsuite:[FAIL: log tables deployed off their pinned Zoltu address].
