From 062a86c8131055bfb363d2018004c49d188b2ed3 Mon Sep 17 00:00:00 2001 From: otobongdev Date: Wed, 30 Sep 2026 13:13:43 +0000 Subject: [PATCH 1/9] chore(deps): dedupe the ed25519/rand_core graph so the test build links The committed lockfile resolved two incompatible major versions of the ed25519-dalek / curve25519-dalek / rand_core family at once. The test build therefore failed before any workspace code was compiled: error[E0277]: the trait bound `ChaCha20Rng: ed25519_dalek::rand_core::CryptoRng` is not satisfied error: could not compile `soroban-env-host` (lib) Reproduce on the previous lockfile with: cargo test -p admin --locked --no-run Re-resolving collapses the duplicates onto one version of each crate (-150/+30 lines) and the admin test target builds and runs again. --- Cargo.lock | 180 +++++++++-------------------------------------------- 1 file changed, 30 insertions(+), 150 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index c0d0cab2e..ef0947f02 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -164,7 +164,7 @@ dependencies = [ "ark-serialize", "ark-std", "derivative", -

A duplicated arm is unreachable, so the first occurrence silently won — if the two ever disagreed the second would be dead code with no warning. `BytesTooLarge` is retained by the Bond arm so coverage is unchanged. The parallel variant inventories had drifted apart and none matched the enum: src/test_errors.rs::all_variants() 110 rows, 5 duplicated, 11 missing variant_table.rs 104 rows, 12 missing discriminant_uniqueness.rs 107 rows, 9 missing enum 116 variants Rather than re-introduce three hand-maintained lists, the two test binaries now `include!("../variant_table.rs")` — the file that already documents itself as the single source of truth — and `all_variants()` derives from it, so a new variant cannot be added to one list and missed in another. Wire codes that moved when colliding discriminants were resolved are updated (ZeroBytes32 109 -> 127, RoleRequired 127 -> 128) and pinned with `const _: () = assert!(...)` guards. cargo test -p credence_errors -> 118 passed, 0 failed cargo clippy -p credence_errors --all-targets -- -D warnings -> clean --- contracts/credence_errors/src/lib.rs | 83 +++-- contracts/credence_errors/src/test_errors.rs | 139 ++------- .../tests/discriminant_uniqueness.rs | 221 +------------- .../tests/variant_coverage_sync.rs | 2 +- contracts/credence_errors/variant_table.rs | 286 ++++++++++++------ 5 files changed, 279 insertions(+), 452 deletions(-) diff --git a/contracts/credence_errors/src/lib.rs b/contracts/credence_errors/src/lib.rs index b4984951a..ab0d764c5 100644 --- a/contracts/credence_errors/src/lib.rs +++ b/contracts/credence_errors/src/lib.rs @@ -21,7 +21,7 @@ // use format!/write! for diagnostics). #![cfg_attr(not(test), deny(clippy::disallowed_macros))] -use soroban_sdk::contracterror;

Decoding restores the file the commit intended to add; the paste had also mangled six tokens inside it, all repaired here (`Ok(()` -> `Ok(())`, `#[config(test)]` / `use supek::*` / `$AX_KEY_LEN` / a stray `}` in a fn signature, and two `&static str` lifetimes that needed `&'static str`). `governable.rs` carried `#[config(test)]]` and a test module that could never compile: typo'd storage keys (`ADDIN_KEY`, `ADFIN_KEY`, `nEw_admin`), an undefined `catch_unwind`/`assert_uneq`, a `Governable` trait that nothing implemented, and calls to SDK APIs that do not exist in the pinned soroban-sdk 22.0.11 (`Address::generate` without `testutils`). Rewritten as a real `#[contract]` mock implementing the trait and driven through its generated client, matching the pattern already used in `credence_treasury::test_flash_loan`. It now pins the documented invariants: uninitialized reads fail deterministically, transfer replaces the admin atomically, an unauthorized caller is rejected with state intact, self-transfer is a silent no-op, the previous admin loses control immediately, and a rejected transfer leaves nothing observable. testutils is now a dev-dependency only, so the release build is unchanged. Two clippy findings in the restored code are fixed at the same time (`(MIN..=MAX).contains(&len)`, module-level `//!` doc, deprecated `register_contract` -> `register`). cargo test -p interfaces -> 26 passed, 0 failed cargo clippy -p interfaces --all-targets --no-deps -- -D warnings -> clean --- crates/interfaces/Cargo.toml | 3 + crates/interfaces/src/consts.rs | 335 +++++++++++++++++++++++++++- crates/interfaces/src/governable.rs | 286 +++++++++++++++--------- 3 files changed, 521 insertions(+), 103 deletions(-) diff --git a/crates/interfaces/Cargo.toml b/crates/interfaces/Cargo.toml index 4d46e62f2..22d956b2d 100644 --- a/crates/interfaces/Cargo.toml +++ b/crates/interfaces/Cargo.toml @@ -5,3 +5,6 @@ edition.workspace = true [dependencies] soroban-sdk = { version = "22.0" } + +[dev-dependencies] +soroban-sdk = { version = "22.0", features = ["testutils"] } diff --git a/crates/interfaces/src/consts.rs b/crates/interfaces/src/consts.rs index 115553358..00d52f8c5 100644 --- a/crates/interfaces/src/consts.rs +++ b/crates/interfaces/src/consts.rs @@ -1 +1,334 @@ -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 /// long keys before they touch persistent state.

charset=UTF-8 Content-Transfer-Encoding: 8bit The file did not parse, so the whole `credence_bond` lib — and therefore every one of its test targets — failed to compile before a single test could run: error: mismatched closing delimiter / unexpected closing delimiter error: unknown start of token: \ (a literal `#[test\n]`) error: expected one of `!` or `::`, found keyword `enum` (`public enum`) Four more corruptions only surface once the file parses, and are fixed here: `Ok(()` -> `Ok(())`, `#[cfg](test)]` -> `#[cfg(test)]`, `...Default::default()` -> `..Default::default()` (and because `IdentityBond` derives no `Default`, the test helper now builds the struct field by field), and `oka_or` -> `ok_or`. The last one also had a real type error: `ok_or` was being handed an already-wrapped `Err`, so `period_end` returned `Result, _>`; it now takes the error value directly. `cargo check -p credence_bond` is clean for this module. The rest of the crate's test build is still broken by unrelated pre-existing work (see the PR description). --- contracts/credence_bond/src/rolling_bond.rs | 53 ++++++++++++++------- 1 file changed, 35 insertions(+), 18 deletions(-) diff --git a/contracts/credence_bond/src/rolling_bond.rs b/contracts/credence_bond/src/rolling_bond.rs index e5f86973a..8931dd16a 100644 --- a/contracts/credence_bond/src/rolling_bond.rs +++ b/contracts/credence_bond/src/rolling_bond.rs @@ -5,7 +5,7 @@ use crate::IdentityBond; /// These are explicit, non-panicking failure modes so callers can /// recover and report diagnosable errors without losing user data. #[derive(Debug, Clone, PartialEq, Eq)] -public enum RollingBondError { +pub enum RollingBondError { /// `bond_start + bond_duration` overflows u64.

No production code, signature, validation or safeguard is changed. What had no coverage at all, and is now pinned: - reads against absent storage (the loading state) — each one is either a stable error or a documented default, none mutates the epoch, and two rejected `initialize` calls leave the contract fully uninitialized so the corrected retry commits exactly once; - the `MaxAdmins` capacity boundary — `MaxAdmins` fits, `MaxAdmins + 1` is rejected without disturbing membership, role lists or the epoch, and the identical retry succeeds once a slot frees; - the paused gate across all 8 privileged mutations — every one fails with `ContractPaused` before authorization or state validation, emits nothing and moves no state, while reads keep working, a duplicate `pause` stays a silent no-op, and `unpause` restores normal operation; - `get_effective_active_admin_count` (previously untested) — it drops a suspended admin without deleting the record, counts it again exactly at `suspended_until` (inclusive `>=`, no second transaction, no epoch bump), and skips a dangling `AdminList` entry without panicking; - `check_role_at_ledger` (previously untested) — side-effect free and rejects a stale ledger with `RoleNotHeldAtLedger`; - deactivation removes authority only: the `AdminInfo` record survives and `reactivate_admin` restores both counts exactly. Also fixes the 30 failing tests this crate already had, all pre-existing and none caused by the new module (a control run with the module removed fails the same 30): - `test_role_events` (21) took an event count "before" a call and subtracted it from the count "after". `env.events().all()` is scoped to the frame of the most recent invocation, so the two numbers came from different frames and the delta was always 0. Each assertion now reads the log immediately after the call it describes, and multi-step ordering is captured per invocation with a new `record_role_events` helper. - `test_ownership_transfer` (5): three mocked contract calls shared one `as_contract` frame, and a mocked authorization frame is consumed by the first `require_auth` (Error(Auth, ExistingValue)); the frame is split per call. Two `#[should_panic]` expectations named wire codes that no longer exist (#107 InvalidPauseAction, #109 unused) where the contract raises #111 AdminUnchanged and #115 NoPendingAdmin. `const _: () = assert!(..)` guards now pin those literals to `credence_errors::ContractError`. - `test_pause_failure_boundaries` (2) and `test_atomic_rollback` (1): the same cross-frame event-count bug. - `test_suspension`: `test_suspend_below_min_admins_rejected` suspended an admin on itself, so it tripped the earlier `AdminUnchanged` (#111) guard and never reached the `MinAdmins` guard it was written for. It now uses MinAdmins = 2 with a peer admin, so the guard under test is the one that fires. `lib.rs` also carries the pre-existing prerequisite repair of a duplicated `is_admin` definition, and `test_basic.rs` / `test_emergency.rs` carry the matching call-site updates; without them this crate does not compile, since HEAD defines `is_admin` twice and `test_basic.rs` calls a set of entry points that do not exist. cargo test -p admin -> 258 passed, 0 failed (was 219 passed, 30 failed) cargo clippy -p admin --all-targets --no-deps -- -D warnings -> clean --- contracts/admin/src/lib.rs | 97 +-- contracts/admin/src/test_atomic_rollback.rs | 8 +- contracts/admin/src/test_basic.rs | 759 ++++++++---------- contracts/admin/src/test_emergency.rs | 5 +- .../admin/src/test_lib_boundary_recovery.rs | 484 +++++++++++ .../admin/src/test_ownership_transfer.rs | 64 +- .../src/test_pause_failure_boundaries.rs | 44 +- contracts/admin/src/test_role_events.rs | 249 ++---- contracts/admin/src/test_suspension.rs | 33 +- 9 files changed, 1028 insertions(+), 715 deletions(-) create mode 100644 contracts/admin/src/test_lib_boundary_recovery.rs diff --git a/contracts/admin/src/lib.rs b/contracts/admin/src/lib.rs index 3bb6498ab..146238dbe 100644 --- a/contracts/admin/src/lib.rs +++ b/contracts/admin/src/lib.rs @@ -216,63 +216,6 @@ impl AdminContract { String::from_str(&e, credence_errors::VERSION) } - /// Return whether `address` is currently an active admin. - /// - /// # Determinism and failure boundaries - /// - /// This is a pure read: it never mutates storage, never advances - /// [`DataKey::ConfigEpoch`], and never emits events.

charset=UTF-8 Content-Transfer-Encoding: 8bit Restore the treasury source tree, resolve the duplicate `get_admin` export (inherent `#[contractimpl]` vs the `Governable` trait impl), call `pausable::require_not_paused` instead of the non-existent `Self::` method, and add `#[cfg(test)] extern crate std/alloc` shims for the `#![no_std]` crate. Update the access-control matrix to the current 1-arg admin entrypoints.

No per-source balance is negative. +//! 3. `CumulativeReceived == CumulativeBySource(ProtocolFee) + CumulativeBySource(SlashedFunds)` (as U256). +//! 4. Cumulative values are monotonically non-decreasing. +//! 5. Actual on-chain token balance of the contract matches `TotalBalance`. +//! 6.
