fix: pass the context for retry

[chlins]

This pull request refactors the retry logic across multiple backend operations by replacing the retryOpts variable with a new defaultRetryOpts variable and appending a context-specific retry option (retry.Context(ctx)) in all retry calls. This change improves the consistency and context-awareness of retries.

Retry Logic Refactor:

• Renamed retryOpts to defaultRetryOpts: Updated the variable name in pkg/backend/retry.go and pkg/backend/processor/options.go to better reflect its purpose as the default retry configuration. [1] [2]

• Added context-specific retry option: Modified retry calls in the following files to append retry.Context(ctx) to defaultRetryOpts, ensuring retries are tied to the provided context:

  • pkg/backend/build.go: Applied changes in the Build function for handling model config and manifest builds. [1] [2]
  • pkg/backend/processor/base.go: Updated the Process function to include the context in retry logic.
  • pkg/backend/pull.go: Enhanced the Pull function for pulling layers, config, and manifests. [1] [2]
  • pkg/backend/push.go: Adjusted the Push function for pushing blobs, config, and manifests. [1] [2] [3]

Summary by CodeRabbit

• Refactor

  • Improved retry logic to better respect cancellation and timeout by integrating context awareness into all retry operations.

Walkthrough

The retry logic across several backend components has been updated to ensure that retry operations respect context cancellation and deadlines. This was achieved by appending a context-aware retry option to the default retry options in all relevant retry calls. Additionally, the retry options variable was renamed for clarity in both backend and processor packages.

Poem

In the warren, code hops anew,
With retries that know what context can do.
Deadlines and cancels now honored with care,
Default options renamed, clarity in the air.
A rabbit’s delight—robustness in view!

pkg/backend/retry.go (1)

25-25: Appropriate variable rename to better reflect its role

The variable rename from retryOpts to defaultRetryOpts better indicates that these are the default options that can be extended with context-specific options elsewhere in the codebase. This aligns with the overall refactoring of the retry logic to be more context-aware.

pkg/backend/processor/options.go (1)

48-48: Consistent variable rename across packages

The rename from retryOpts to defaultRetryOpts maintains consistency with the same change in pkg/backend/retry.go. This consistency is important since these options are used across multiple packages.

pkg/backend/push.go (3)

82-82: Enhanced context awareness for blob push retries

The retry logic now properly respects the context lifecycle by appending retry.Context(ctx) to the default retry options. This ensures that if the context is canceled or times out, the retry attempts will stop, preventing unnecessary work.

---

93-93: Enhanced context awareness for config push retries

Similar to the blob push retry logic, the config push retry logic now appropriately respects the context lifecycle, ensuring proper resource management.

---

105-105: Enhanced context awareness for manifest push retries

The manifest push retry logic has been updated to respect the context lifecycle, completing the consistent pattern of context-aware retries throughout the push operation.

pkg/backend/processor/base.go (1)

127-127: Improved retry behavior with context awareness

The retry mechanism now properly respects the context lifecycle by appending retry.Context(ctx) to the default retry options. This complements the existing context handling in the error group (lines 80-82) by ensuring that individual retries also stop when the context is canceled, preventing unnecessary work and improving resource utilization.

pkg/backend/pull.go (3)

98-98: Properly integrating context with retry operations.

The update ensures retry operations respect context cancellation and deadlines by appending retry.Context(ctx) to default retry options. This is a good practice since it allows retries to be terminated if the parent context is cancelled.

---

115-115: Context-aware retry for config pulling.

This change ensures that config pulling respects context cancellation by adding retry.Context(ctx) to the retry options. The implementation is consistent with the other retry operations.

---

122-122: Context-aware retry for manifest pulling.

The update properly integrates context with the retry operation for manifest pulling, ensuring that retries will stop if the context is cancelled or times out.

pkg/backend/build.go (2)

132-132: Context-aware retry for config building.

The change properly integrates context with the retry mechanism for model config building. This ensures that if the parent context is cancelled or times out, retry operations will also stop.

---

150-150: Context-aware retry for manifest building.

This change properly ties the retry operation to the provided context, ensuring the manifest building retry operation can be cancelled appropriately. This implementation is consistent with the other retry operations.
