An exchange now gets at most one retry, so the attempts made from one original form a chain you can read end to end — and retrying continues from the newest attempt rather than forking off an old one.

The rule is enforced in XchangeService, so every route to a retry is held to it: by hand, in bulk, or a policy coming due. No unique index — exchanges retried before this can already have forked, and an index that won't create over inherited data is worse than none. The scheduled path drops such a retry with a reason instead of throwing, which would have left the schedule for RetryJob to fail on forever.

Reading it: a retrytree endpoint walks up to the original and back down, so any attempt returns the same tree and old forks show as branches rather than being hidden. Its own endpoint, not part of the exchange search — that query is already the expensive one. Rows carry a hasRetry bit instead, so an exchange with no chain either side costs no request at all.

Bulk retry takes a whole filter rather than the ids on one page, resolves each selection to the end of its chain, dedupes, and can be previewed first — preview and execution share one planner, so what you confirm is what runs. Capped at 500 per request.

Two things worth a reviewer's attention:

  • Retry and BulkRetry had no permission check at all; only RunNow called EnsurePermission. The UI hid the button, the API accepted the call from any signed-in account. Now guarded, with a test — PermissionGuardTests couldn't have caught it, since those test EnsurePermission itself rather than whether a handler calls it.
  • Promoted properties that carry no values name nothing (merchant= orderRef= destination= names every exchange of its type equally), so those fall back to the id. That applies to the exchanges table and scheduled retries as well as the new chain.

Tested: 12 new integration tests, 2 new e2e specs, a unit test for the naming rule. Verified by hand against local data containing a real 25-attempt forked chain.

Enforced in XchangeService so every path — by hand, in bulk, or a policy coming
due — is held to it, and retrying a spent exchange points at its newest attempt
instead. Adds a retrytree endpoint, and a bulk retry that takes a whole filter,
resolves each selection to the end of its chain and can be previewed first.

Retry and BulkRetry were also accepting the call from any signed-in account.

The drawer shows every attempt with the current one marked, a forked parent says
so, and the list can select everything a filter matches rather than one page.

Promoted properties that carry no values name nothing, so those fall back to the
id — in the table and scheduled retries too, not just the chain.

📝 Summary

Summary

  • Enforces one retry per exchange and continues retries from the newest attempt.
  • Adds the retrytree endpoint and HasRetry search data.
  • Adds filtered bulk retry with preview, chain resolution, deduplication, exclusions, and a 500-exchange limit.
  • Adds Operate permission checks to retry operations.
  • Updates the UI to display retry chains and select all filtered exchanges.
  • Falls back to exchange IDs when promoted properties have no value.

Risk

risk:medium

Retry enforcement changes manual, bulk, and scheduled workflows. Bulk selection and filter handling also change API behavior and query semantics.

Security-sensitive areas

  • Retry and BulkRetry now enforce Operate permissions.
  • Filter-based bulk retry accepts server-resolved selections and exclusion IDs.
  • Retry-tree and exchange search endpoints expose retry relationships and metadata.

Test coverage

  • Adds 12 integration scenarios for retry chains, bulk planning, permissions, scheduled retries, search, and retrytree.
  • Adds two Playwright end-to-end tests.
  • Adds unit coverage for promoted-property naming fallback.

Operational concerns

  • No database migration is described.
  • The bulk retry API and client contract changed from ID lists and counts to selection and plan objects.
  • Rollback requires matching frontend and backend API versions.
  • Bulk retry is capped at 500 exchanges and can report skips instead of failing the whole request.

Walkthrough

The change enforces one retry per exchange, adds server-side bulk retry planning and previews, exposes retry trees, updates search and API contracts, and adds web selection, display, and integration coverage.

Changes

Retry planning and backend enforcement

Layer / File(s) Summary
Selection planning and contracts
SW.Bitween.Api/Resources/Xchanges/BulkRetryPlanner.cs, SW.Bitween.Api/Resources/Xchanges/XchangeFilters.cs, SW.Bitween.Api/Resources/Xchanges/Search.cs, SW.Bitween.Sdk/Model/Xchange.cs
Bulk retry supports explicit IDs or filter-based selection, exclusions, retry-chain substitution, limits, skips, promoted properties, and HasRetry reporting.
Permission checks and retry execution
SW.Bitween.Api/Resources/Xchanges/BulkRetry.cs, SW.Bitween.Api/Resources/Xchanges/BulkRetryPreview.cs, SW.Bitween.Api/Resources/Xchanges/Retry.cs, SW.Bitween.Api/Services/XchangeService.cs
Retry handlers enforce permissions. Bulk retry returns a plan and records per-exchange skips. The service blocks duplicate retries and scheduled retries that already have a replacement.
Retry-tree query
SW.Bitween.Api/Resources/Xchanges/RetryTree.cs
The new query handler returns ancestor and descendant attempts with cycle detection, depth truncation, status data, scheduled retry data, and promoted properties.

Web integration and interface

Layer / File(s) Summary
API transport and types
SW.Bitween.Web/ClientApp/src/api/client.ts, SW.Bitween.Web/ClientApp/src/api/http/exchanges.ts, SW.Bitween.Web/ClientApp/src/api/queryKeys.ts, SW.Bitween.Web/ClientApp/src/api/types.ts
The client sends bulk retry selections, retrieves previews and retry trees, maps retry plans, and exposes retry-chain fields.
Exchange selection and retry dialog
SW.Bitween.Web/ClientApp/src/pages/exchanges/ExchangesPage.tsx, SW.Bitween.Web/ClientApp/src/pages/exchanges/shared.tsx
The page supports selecting all filtered exchanges with exclusions. The dialog displays server-resolved retry counts, substitutions, skips, and over-limit state.
Retry-chain display and identity rendering
SW.Bitween.Web/ClientApp/src/pages/exchanges/RetryChain.tsx, SW.Bitween.Web/ClientApp/src/pages/exchanges/ExchangeDrawer.tsx, SW.Bitween.Web/ClientApp/src/components/config/shared.tsx, SW.Bitween.Web/ClientApp/src/pages/scheduled-retries/ScheduledRetriesPage.tsx
The drawer and chain component show retry history, newest attempts, statuses, origins, and truncation. Promoted-property rendering falls back to exchange IDs when values are empty.

Validation

Layer / File(s) Summary
Retry workflow tests
SW.Bitween.IntegrationTests/Tests/RetryChainTests.cs, SW.Bitween.IntegrationTests/Tests/DelayedRetriesTests.cs, SW.Bitween.IntegrationTests/Tests/RetryJobTests.cs, SW.Bitween.Web/ClientApp/e2e/exchanges.spec.ts, SW.Bitween.Web/ClientApp/src/components/config/__tests__/promotedProps.test.ts
Integration and end-to-end tests cover retry-chain limits, bulk selection, previews, permissions, retry-tree responses, search fields, UI state, and promoted-property fallbacks.

Enforce the one-retry invariant atomically.

FindRetryOf and _dbContext.Add form a check-then-create race. Two concurrent manual, bulk, or scheduled retries can both observe no child and create separate retries. Both retries can execute downstream handlers and duplicate external side effects.

Preserve historical forks, but serialize new retry creation. Use a unique retry-claim record keyed by the parent exchange, or lock the parent row in a transaction that includes the claim and save. Acquire the claim before AddFile to prevent orphaned files when another request wins.

Search beyond the first five failed rows

The E2E setup does not guarantee an un-retried failed exchange. failedRows contains only the current 25-row page, so five already-retried rows can make the assertion fail before the retry-chain flow runs. Search all pages, or create an exchange with a deterministic failed result. failedRows.count() alone covers only the current page.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Make bulk retry preview and execution use the same reset-aware plan.

When reset is true, BulkRetry skips exchanges whose subscription is missing, but BulkRetryPlanner ignores request.Reset and subscription existence. The preview can therefore report an exchange in willRetry while execution skips it. Lift the reset state into ExchangesPage, include it in the preview query key, and pass it to previewBulkRetry. Update BulkRetryPlanner to apply the same reset-dependent subscription check before adding targets, while retaining the execution-time race check. Add coverage for both preview and execution with reset: true and a missing subscription, and preserve the current reset: false behavior.

One exchange with unreadable input no longer aborts a whole bulk retry, an
unreadable status is refused rather than dropped (which widened the selection to
everything), the tree bounds its size and not just its depth, and a too-long list
of ids reports its own count.

The plan now answers for the reset actually being asked about, so it can no
longer promise a retry that execution then skips.
