Conversation
Sent once per subscription and group, resolved policy -> group -> subscription override, and delivered through a new native SMTP handler on its own bus queue.
📝 WalkthroughSummary
Riskrisk:high The change modifies retry evaluation, budget consumption, notification delivery, public SDK contracts, and database schemas. Errors can cause missed, duplicate, or unintended alerts. Security-sensitive areas
Test coverage impactAdds unit tests for alert resolution and SMTP handling. Adds MailHog integration tests for delivery, retry after failure, duplicate prevention, and insecure SMTP rejection. Expands retry-policy tests for concurrency, reset behavior, validation, secret handling, persistence, usage reporting, and attempt filtering. Deployment and operational concerns
WalkthroughChangesRetry budget alerts
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to This PR adds retry-budget alerting and changes handler configuration behavior, but a masked credential may be sent to a newly selected handler and failed alerts may be permanently lost instead of retried. These security and availability issues make the PR unsafe to merge until corrected. Possibly related PRs

Inline comments:
In `@SW.Bitween.Api/Domain/XchangeNotification.cs`:
- Around line 23-29: Update ForRetryBudgetAlert and the
RetryAlertService.Process flow to represent retry-budget alert delivery with an
explicit pending/completed state rather than using null NotifierId as the sent
marker. Atomically claim each alert under a unique delivery constraint before
sending, mark the claim completed only after success, and release or make failed
claims retryable so transient failures can be redelivered without allowing
concurrent duplicates.
In `@SW.Bitween.Api/Resources/RetryPolicies/Attempts.cs`:
- Around line 45-88: Validate request.GroupId against the retry policy
identified by key before querying attempts, using the policy’s own Groups
relationship; return the established not-found response for unknown or foreign
groups, while leaving the existing attempt query and ordering unchanged for
valid groups.
In `@SW.Bitween.Api/Resources/RetryPolicies/SaveAlertOverride.cs`:
- Around line 48-70: Update the save flow around the existing RetryAlertOverride
lookup and insert so concurrent saves for the same SubscriptionId and GroupId do
not surface an unhandled uniqueness exception. Use an atomic upsert where
supported, or catch the provider-specific duplicate-key error and retry by
updating the existing row, while preserving the Inherit removal behavior.
In `@SW.Bitween.Api/Resources/RetryPolicies/Update.cs`:
- Around line 40-53: Wrap the parent mutation and dependent-row cleanup in a
single transaction in Update.cs lines 40-53: begin before SaveChangesAsync,
execute both RetryGroupUsage and RetryAlertOverride deletions within it, and
commit after the second delete. Apply the same transaction flow in Delete.cs
lines 36-47 around DeleteByKeyAsync and both cleanup calls, committing only
after all operations succeed.
In `@SW.Bitween.Api/Resources/RetryPolicies/Usage.cs`:
- Around line 65-68: Update the groups filter in the policy listing to require a
non-null Budget with MaxAttemptsTotal greater than zero. Exclude zero- and
negative-attempt budgets so only groups that can consume and exhaust a budget
remain listed.
- Around line 72-80: Replace the per-pair FirstOrDefault scans in the
subscription/group loop with composite-key dictionaries for overrides and
usages, keyed by SubscriptionId and GroupId. Confirm RetryGroupUsage is unique
on that composite key before using ToDictionary; preserve the existing per-pair
matching behavior and duplicate handling.
In `@SW.Bitween.Api/Services/RetryAlertService.cs`:
- Around line 112-126: Extract the duplicated native-versus-serverless dispatch
from RetryAlertService and XchangeService.NotifyResult into a shared service
method accepting handlerId, handlerProperties, correlationId, and payload.
Preserve the existing NativeAdapterDiscoveryService prefix check, native handler
resolution, and serverless StartAsync/InvokeAsync flow, then update both callers
to use the shared method.
- Around line 35-37: Update the idempotency guard in Send to match only
RetryBudgetAlertName notifications and only successful delivery records,
excluding failure rows created by ForRetryBudgetAlert. Preserve the early return
for an already-successfully-sent retry-budget alert while allowing failed
deliveries to be retried.
In `@SW.Bitween.Api/Services/RetryGroupBudget.cs`:
- Around line 89-100: Make the exhaustion claim and RetryBudgetExhaustedEvent
durable as one operation: update ClaimExhaustionAlert in
SW.Bitween.Api/Services/RetryGroupBudget.cs (lines 89-100) to write an outbox
record in the same independent write that sets ExhaustedNotifiedOn. Update the
handling in SW.Bitween.Api/Services/XchangeService.cs (lines 502-511) to consume
that outbox record or re-derive exhaustion from RetryGroupUsage on redelivery,
rather than relying only on deferred SaveChangesAsync dispatch.
In `@SW.Bitween.IntegrationTests/Tests/RetryAlertServiceTests.cs`:
- Around line 37-42: Set an explicit short timeout on every HttpClient created
in the MailHog-related tests, including the client in MailHogIsReachable and the
other three instances. Reuse the same timeout value consistently so
non-responsive MailHog requests fail promptly.
In `@SW.Bitween.IntegrationTests/Tests/RetryPolicyTests.cs`:
- Line 870: Update the setup in the RetryPolicyTests flow around
RetryGroupBudget.TryConsume to capture its result and assert that the initial
groupId claim was granted before starting the racers, with a clear
setup-specific failure message.
- Line 533: Update the AlertHandlerId assignment in the retry policy round-trip
test to use the registered exact identifier NativeSmtpHandler instead of the
invalid native.smtp alias, preserving the case-insensitive handler lookup
contract.
In `@SW.Bitween.NativeAdapters/SmtpHandler/NativeSmtpHandler.cs`:
- Around line 51-61: Update the ConnectAsync options in NativeSmtpHandler to use
SslOnConnect when _options.UseTls is true with port 465, StartTls for other
TLS-enabled ports, and None otherwise. Before AuthenticateAsync, when a password
is supplied, validate client.IsSecure and throw if the connection is not
encrypted; retain the existing username selection and authentication flow for
secure connections.
In `@SW.Bitween.PgSql/Migrations/20260817103433_RetryBudgetAlerts.cs`:
- Around line 119-128: Before restoring the non-null NotifierId constraint in
the rollback of SW.Bitween.PgSql/Migrations/20260817103433_RetryBudgetAlerts.cs
lines 119-128, delete or migrate XchangeNotification rows with null retry-alert
owners. Apply the same cleanup before the constraint restoration in
SW.Bitween.MsSql/Migrations/20260817103506_RetryBudgetAlerts.cs lines 105-113
and SW.Bitween.MySql/Migrations/20260817103452_RetryBudgetAlerts.cs lines
111-119, preserving rollback success without invalid null values.
In `@SW.Bitween.Sdk/Model/AutoRetry/IRetryGroupBudget.cs`:
- Line 43: Preserve the existing Boolean-returning IRetryGroupBudget.TryConsume
contract for compatibility, marking it deprecated if appropriate, and introduce
a distinct method for the RetryBudgetClaim result. Update implementations and
callers to use the new claim method where claim details are required without
changing the original method signature.
In `@SW.Bitween.Sdk/Model/RetryPolicyModel.cs`:
- Around line 75-89: Update the response construction involving
OverrideHandlerProperties and ResolvedHandlerProperties so public usage
responses expose handler identity and non-secret metadata only. Apply each
handler’s existing secret-property policy to remove credentials such as API keys
before serialization, while preserving the non-secret properties needed by the
override workflow.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
Make retry-budget alert delivery retryable and atomic.
ForRetryBudgetAlert records both failed and successful sends. RetryAlertService.Process treats every row with a null NotifierId as already sent. A transient handler failure therefore suppresses all later delivery attempts.
The read-then-send-then-insert flow also allows concurrent redeliveries to send duplicates. Use an atomic, uniquely constrained delivery claim with an explicit delivery state. Mark it complete only after a successful send. Release or retry failed claims.

Handle concurrent override saves
RetryAlertOverride already has a composite primary key on (SubscriptionId, GroupId) in all provider migrations. Duplicate rows cannot be created.
Concurrent read-then-insert operations can still raise an unhandled uniqueness exception. Use an atomic upsert, or catch the provider-specific uniqueness error and retry the update.

Preserve compatibility for IRetryGroupBudget.TryConsume.
SimplyWorks.Bitween.Sdk exposes this interface. Changing Task<bool> to Task<RetryBudgetClaim> breaks existing implementations and callers at compile time. Retain the Boolean method as a deprecated compatibility member and add a distinct claim-returning method, or release this as a documented major-version breaking change.

97-143: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick winA swallowed exception means no redelivery ever happens, so the failure path never recovers.
The remark at lines 101-103 states that a failed send "leaves the way open for a redelivery to try again". No redelivery occurs.
Sendcatches every exception, records the failure row, and returns normally. The bus therefore acknowledges the message as processed and never redelivers it. The only path that reaches the retry is a manual second call toProcess, which is exactly what the integration test does at line 279 ofSW.Bitween.IntegrationTests/Tests/RetryAlertServiceTests.cs. In production, one transient SMTP failure loses the alert permanently.Record the failure, save it, then rethrow so the bus applies its backoff. Bound the attempts by counting existing failure rows for the same xchange if unbounded redelivery is a concern.
Proposed fix
catch (Exception ex) { logger.LogError(ex, "Retry budget alert for xchange {XchangeId} could not be delivered through {HandlerId}.", xchangeId, target.HandlerId); dbContext.Add(XchangeNotification.ForRetryBudgetAlert(xchangeId, ex.ToString())); + await dbContext.SaveChangesAsync(); + throw; } await dbContext.SaveChangesAsync();🤖 Prompt for AI Agents

Do not restore masked properties after a handler change.
AdapterSecretProperties.Merge restores every "__private__" value by property key. It does not verify the handler identity. A caller can change AlertHandlerId, retain a masked Password property, and cause the stored SMTP password to be sent to the newly selected handler.
SW.Bitween.Api/Resources/RetryPolicies/Update.cs#L44-L59: restore masked group and policy properties only when the incoming handler ID matches the corresponding stored handler ID.SW.Bitween.Api/Resources/RetryPolicies/SaveAlertOverride.cs#L67-L80: include inherited or existing properties as a restore source only when its handler ID matchesrequest.AlertHandlerId.
Add coverage for a handler change with a masked property. Verify that the new handler configuration does not receive the previous handler credential.
