Issue being fixed or feature implemented

A block containing a signed service update could clear a local Platform ban before a later block check rejected it. EvoDB rolled back, but the ban flag, height watermark and candidate deterministic-list caches remained changed. This affects local Platform metadata; it does not make the rejected block consensus-valid.

What was done?

Apply service-update ban resets synchronously after successful active-chain tip connection, after database commit, flushing and tip update. Verification, crash rollforward and background validation do not replay these local resets. When ConnectBlock fails, roll back the block's EvoDB transaction first and then drop the candidate deterministic-list and diff caches, so public list lookups agree with rolled-back EvoDB. Rolling back first matters because other threads can read the open transaction: a concurrent lookup such as protx info could otherwise cache the candidate again after eviction. Successful service-update behavior, metadata height precedence and existing disconnect behavior remain intact.

How Has This Been Tested?

Local macOS/arm64 make -j1, all 43 evo_dip3_activation_tests cases, changed-line clang-format, include lint, whitespace lint and git diff --check passed. The new public-interface unit fixture registers an EvoNode and establishes a Platform ban, then submits a service-update block with an incorrect coinbase MN-list root. It checks unchanged tip, ban flag/watermark and cache agreement with a fresh manager, then connects the valid counterpart and checks revival. With baseline production code, the fixture reported three expected failures covering metadata and cache state. After the rollback-ordering follow-up, make -j1, all 43 evo_dip3_activation_tests cases, p2p_platform_ban.py, feature_block.py and lints passed again. After removing an assertion that probed a private EvoDB key, evo_dip3_activation_tests (including platform_ban_reset_requires_successful_connection) passed again. The ordering is verified by reading the code; no concurrent reproduction was run. Verification, rollforward and background routing were inspected in source; no daemon crash, DKG impact, flush-failure injection or crash-recovery reproduction was performed.

Breaking Changes

None. No consensus acceptance rule changes.

Walkthrough

Platform-ban resets now run after a successful active-chain connection instead of during deterministic masternode block processing. If block connection fails, ConnectTip rolls back the EvoDB transaction and discards the block’s deterministic masternode data. A regression test checks the rejected-block and successful-connection behavior.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

A restart at the wrong point can leave a Platform ban in place after a successful service update. Make the reset recoverable before merging.

Final validation — Phase 1 + Phase 2

At head 617cbde, deferring Platform revival until successful active-chain connection correctly prevents rejected blocks from changing local ban metadata. However, the new cache cleanup runs before EvoDB rollback, allowing a concurrent reader to restore rejected candidate state to the caches and defeating the stated cache-consistency guarantee. Verification was static only; the supplied CI snapshot shows ClangFormat passing and container builds queued, with build/test results still pending.

Valid; fixed in 65fed04. ConnectTip() now calls dbTx->Rollback() before DiscardDeterministicMNBlock().

The race checks out in the source:

  • Threads other than the validation thread resolve to the default EvoDB identity, so Read() sees the candidate's open cur_transaction.
  • protx info drops cs_main before calling GetListForBlock().
  • GetListForBlockInternal() caches whatever diff or snapshot it reads.

With the rollback first, a reader holding the manager lock either finishes before eviction, so its candidate entries are erased, or starts afterwards, when the rolled-back transaction no longer holds candidate data. The destructor then does nothing.

Validation: make -j1, evo_dip3_activation_tests (all 43 cases, including platform_ban_reset_requires_successful_connection), p2p_platform_ban.py, feature_block.py and lints all pass. The ordering was verified by reading the code. No concurrent reproduction was run; that would need a test-only sync point inside ConnectTip().

Resolved (re-reviewed at 65fed043): Confirmed your fix: ConnectTip() now clears the candidate transaction under the EvoDB lock before DiscardBlock() acquires the manager lock, so readers already reconstructing candidate state finish before eviction and subsequent readers cannot reload the rolled-back writes. The scoped committer records the explicit rollback and its destructor does not repeat it; this confirmation is static, not a concurrent reproduction.

Re-review — Final validation — Phase 1 + Phase 2

Verified the complete diff at 65fed04: Platform revival is deferred until successful active-chain connection, and rollback-before-eviction fixes the previously reported cache race. No remaining correctness blockers were found; the duplicate commit-history findings are consolidated into one non-blocking suggestion. Verification was static, and the supplied CI snapshot still shows build and validation checks queued or pending.

🟡 Suggestion: Fold the rollback-order correction into the original fix
<commit:65fed0439c>:1

Commit 65fed04 adds only an explicit rollback and its explanatory comment immediately before the cache eviction introduced by 617cbde. It completes the rejection-state cleanup from the implementation commit rather than introducing an independent change; leaving them separate preserves an intermediate implementation with the cache-repopulation race identified during review. Fold the corrective commit into 617cbde before merge, retaining its rollback-order rationale in the combined commit message. This follows CONTRIBUTING.md's guidance on squashing fine-grained fixups and keeps the complete fix together for blame and bisect.

Re-review — Final validation — Phase 1 + Phase 2

Independently reviewed the complete PR diff at 54c4ba3 and found no remaining in-scope defects. Platform revival now occurs only after successful active-chain connection, and rejected-block cleanup rolls back EvoDB before evicting both deterministic-list caches; the prior blocking finding is fixed and the commit-squashing suggestion is withdrawn. Verification was static only: the supplied exact-head CI snapshot shows formatting and preliminary checks passing, while container builds and title checks remain queued.

Another thread can read the open EvoDB transaction. Between evicting a
rejected candidate's masternode-list caches and the transaction rollback
in the destructor, a concurrent lookup such as protx info could read the
candidate's diff and cache it again, leaving rejected state cached after
the rollback. Roll back first, then evict under the manager lock.

Make the deferred Platform ban reset crash-recoverable.

When FlushStateToDisk persists a block, a process exit before ResetPlatformBans can leave the connected service update without its local metadata reset. LoadChainTip restores the tip but does not replay the reset, and rollforward processing also omits it. The Platform ban can therefore remain set after restart until a later service update.

Persist a pending reset with the block state, or reconcile connected provider-service updates during startup after loading the chain tip.

Re-review — Final validation — Phase 1 + Phase 2

Static review of the complete diff at de97174 confirms that Platform revival is deferred until successful active-chain connection and rejected-block EvoDB writes are rolled back before cache eviction; no blocking correctness issue remains. One nonblocking regression-coverage gap remains because the fixture does not verify rejected-candidate list lookups despite the PR description claiming that comparison. No local builds or tests were run; the supplied CI snapshot shows successful completed builds, standard Linux tests and lints, with ASan/TSan tests and the multiprocess build still pending.

- [SUGGESTION] src/test/evo_deterministicmns_tests.cpp:3964-3968: Cover rejected-candidate state through the public list lookup
  The fixture checks rejection and unchanged Platform metadata, then connects the valid counterpart under a different block hash. It never calls GetListForBlock(rejected_index), so removing DiscardDeterministicMNBlock() would leave the rejected candidate's list and diff cached without any current assertion observing that stale state. Before connecting the valid counterpart, add a public list lookup that verifies the rejected service update is not returned and compares the result with a fresh CDeterministicMNManager backed by the same rolled-back EvoDB. This directly covers the cache-consistency behavior introduced by this PR without accessing private database keys or requiring a concurrent reproduction, and restores the comparison currently claimed in the PR description.

🟡 Suggestion: Cover rejected-candidate state through the public list lookup
