From b143eab0ac7e269aebbc99909a0db32e97c8f505 Mon Sep 17 00:00:00 2001 From: Divine-designs Date: Mon, 29 Jun 2026 18:25:14 +0100 Subject: [PATCH] feat(contract): pool validations + multisig emergency cancel (#1119, #1122, #1130, #1131) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes #1119, #1122, #1130, #1131. Issue #1122 — outcome description bounds: - New constants MAX_OUTCOME_DESCRIPTION_LEN (128) and MIN_OUTCOME_DESCRIPTION_LEN (1). - validate_pool_invariants now panics if any outcome description is empty or exceeds 128 bytes, preventing unbounded persistent-storage growth and useless empty labels. - New errors OutcomeDescriptionTooLong (130) and OutcomeDescriptionEmpty (131). Issue #1130 — staking deadlines must be in the future: - create_pool now returns the typed PredifiError::DeadlineInPast (132) when end_time < current_time, replacing the legacy assert string ("end_time must be in the future") which remains as a boundary diagnostic for end_time == current_time. - Non-zero start_time strictly in the past is also rejected. - start_time == 0 remains the "open immediately" sentinel. Issue #1131 — initial-liquidity safety margin: - New constant INITIAL_LIQUIDITY_SAFETY_MARGIN_BPS (100 = 1%). - When max_total_stake > 0, initial_liquidity must cover at least 1% of max_total_stake; otherwise PredifiError::InitialLiquidityBelowSafetyMargin (133) is raised. Skipped entirely when max_total_stake == 0 ("no cap"). Issue #1119 — multi-sig emergency cancellation: - New constant EMERGENCY_CANCEL_MULTISIG_THRESHOLD (2 distinct approvals). - New entry point `emergency_cancel_pool(approver, pool_id, reason)`. Admin/operator addresses each call once; the first call records the reason and proposer's approval, subsequent distinct calls add their approval. Once the threshold is reached the pool transitions to MarketState::Canceled via the same path as cancel_pool. Same-address re-approval is rejected with EmergencyCancelAlreadyApproved (135). Non-privileged callers are rejected with Unauthorized (10). - New DataKey variants EmergencyCancelApprovers(pool_id) and EmergencyCancelReason(pool_id), both cleared on execution. - New read-only `get_emergency_cancel_approvals(pool_id) -> Vec
`. Baseline fix (required for any test build to succeed): - `mod events; pub use events::*;` re-exports event types into the lib module so usages like `ClaimWindowUpdateEvent` resolve. - Added missing `TimeConstraintError = 84` variant referenced in two existing call sites. These broke the lib test build on main; the baseline now compiles cleanly for both `cargo build --release --target wasm32-unknown-unknown` and `cargo test --lib`. Tests: - 13 new tests covering all four issues (3 for #1122, 3 for #1130, 3 for #1131, 4 for #1119). - 1 existing test (test_pool_end_time_at_leap_day_already_past) updated to expect the typed `#132` error instead of the legacy assert message — same behavior, stronger error reporting. Verification: - `cargo test -p predifi-contract --lib` → 386 passed, 0 failed. - `cargo build --release --target wasm32-unknown-unknown -p predifi-contract` → clean. --- .../predifi-contract/src/constants.rs | 23 ++ .../contracts/predifi-contract/src/lib.rs | 212 +++++++++++- .../contracts/predifi-contract/src/test.rs | 319 +++++++++++++++++- 3 files changed, 551 insertions(+), 3 deletions(-) diff --git a/contract/contracts/predifi-contract/src/constants.rs b/contract/contracts/predifi-contract/src/constants.rs index 3815c745..264e7007 100644 --- a/contract/contracts/predifi-contract/src/constants.rs +++ b/contract/contracts/predifi-contract/src/constants.rs @@ -56,6 +56,29 @@ pub const UNRESOLVED_OUTCOME: u32 = u32::MAX; /// Pools with end_time beyond current_time + MAX_POOL_DURATION are rejected. pub const MAX_POOL_DURATION: u64 = 31_536_000; +/// Maximum length (in bytes/chars) of a single outcome description. +/// Issue #1122 — bounds outcome descriptions so a pool with N outcomes +/// cannot blow up persistent storage with arbitrarily long strings. +pub const MAX_OUTCOME_DESCRIPTION_LEN: u32 = 128; + +/// Minimum length (in bytes/chars) of a single outcome description. +/// Issue #1122 — rejects whitespace-only / empty outcome labels. +pub const MIN_OUTCOME_DESCRIPTION_LEN: u32 = 1; + +/// Initial-liquidity safety margin in basis points relative to +/// `max_total_stake` (issue #1131).
