44-55: LGTM: ClearCaches function implementationThe
ClearCachesfunction is well-implemented, aligning with the PR objective. It correctly iterates over all caches, attempts to clear each one, and combines any errors usingerrors.Join.Consider a minor improvement:
To ensure all caches are attempted to be cleared even if an error occurs, you could modify the error handling slightly:
func ClearCaches(ctx context.Context) error { l := ctxzap.Extract(ctx) l.Debug("clearing caches") - var err error + var errs []error for _, cache := range caches { - err = cache.Clear() - if err != nil { - err = errors.Join(err, err) + if err := cache.Clear(); err != nil { + errs = append(errs, err) } } - return err + return errors.Join(errs...) }This change ensures that the function attempts to clear all caches, collecting any errors along the way, rather than potentially stopping at the first error.

173-177: LGTM: HTTP cache clearing added with appropriate error handling.The addition of HTTP cache clearing at the start of the sync process is a good improvement. It ensures that fresh data is fetched during the sync operation. The error handling is appropriate, allowing the sync to continue even if cache clearing fails.
Consider adding more context to the error log, such as:
- l.Warn("error clearing http caches", zap.Error(err)) + l.Warn("error clearing http caches at the start of sync", zap.Error(err), zap.String("sync_id", syncID))This will provide more information for debugging purposes if needed.

1-1161: Overall assessment: Well-implemented cache clearing functionality.The changes introduced in this PR effectively add HTTP cache clearing at the start of the sync process. This improvement can help ensure that the sync operation works with fresh data, potentially reducing inconsistencies or stale information.
Key points:
- The new functionality is well-integrated into the existing
Syncmethod.- Proper error handling is implemented, allowing the sync to continue even if cache clearing fails.
- The changes are focused and don't introduce unnecessary complexity.
While the current implementation is good, consider the following for future improvements:
- Add a configuration option to enable/disable cache clearing, allowing for more flexibility in different environments or scenarios.
- Implement a mechanism to track and report on the impact of cache clearing on sync performance and data freshness.

42-42: LGTM: Addition of caches sliceThe addition of the
caches []GoCachevariable at the package level is appropriate for storing multiple cache instances. This change aligns well with the PR objective of clearing HTTP caches at the start of a sync.
134-134: LGTM: Appending new cache to caches sliceThe addition of
caches = append(caches, cache)in theNewBaseHttpClientWithContextfunction is correct and necessary. This change ensures that each new cache instance is added to thecachesslice, allowing theClearCachesfunction to manage all created caches effectively.
Line range hint
1-465: Overall assessment: Changes effectively implement cache clearing functionalityThe changes in this file successfully implement the ability to clear HTTP caches at the start of a sync, aligning well with the PR objective. The new
cachesslice,ClearCachesfunction, and the modification toNewBaseHttpClientWithContextwork together cohesively to manage and clear multiple cache instances.A minor improvement was suggested for the
ClearCachesfunction to ensure all caches are attempted to be cleared even if an error occurs with one of them. Otherwise, the implementation is solid, well-structured, and follows good coding practices.These changes should effectively improve the synchronization process by ensuring a clean slate for HTTP caches at the start of each sync operation.

16-16: LGTM: New import added for HTTP cache management.The addition of the
uhttpimport is consistent with the new cache clearing functionality being introduced.

Looks good to me, but I'd leave a docstring on caches explaining what it is.
