This commit refactors the application's error handling mechanism by introducing a new standardized error type, `types.NewAPIError`. It also renames common JSON utility functions for better clarity.
Previously, internal error handling was tightly coupled to the `dto.OpenAIError` format. This change decouples the internal logic from the external API representation.
Key changes:
- A new `types.NewAPIError` struct is introduced to serve as a canonical internal representation for all API errors.
- All relay adapters (OpenAI, Claude, Gemini, etc.) are updated to return `*types.NewAPIError`.
- Controllers now convert the internal `NewAPIError` to the client-facing `OpenAIError` format at the API boundary, ensuring backward compatibility.
- Channel auto-disable/enable logic is updated to use the new standardized error type.
- JSON utility functions are renamed to align with Go's standard library conventions (e.g., `UnmarshalJson` -> `Unmarshal`, `EncodeJson` -> `Marshal`).
This update replaces instances of DecodeJson and DecodeJsonStr with UnmarshalJson and UnmarshalJsonStr in various relay handlers, enhancing code consistency and clarity in JSON processing. The changes improve maintainability and align with recent refactoring efforts in the codebase.
Backend
- controller/ratio_sync.go
• Parse /api/pricing response and convert to ratio / price maps.
• Introduce confidence heuristic (model_ratio = 37.5 && completion_ratio = 1) to flag unreliable data.
• Include confidence map when building differences and filter “same”/empty entries.
- dto/ratio_sync.go
• Add `ID` to UpstreamDTO, `upstreams` to UpstreamRequest, and `Confidence` to DifferenceItem.
Frontend
- ChannelSelectorModal.js
• Re-implement with table layout, pagination, search, endpoint-type selector and mobile support.
- UpstreamRatioSync.js
• Send full upstream objects, add ratio-type filter, confidence badges/tooltips, retain endpoints.
• Leverage ChannelSelectorModal’s pagination reset.
- ChannelsTable.js – fix tag color for disabled status.
- en.json – add translations for new UI labels.
Motivation
These changes let users sync model ratios / prices from different upstream endpoints and visually identify potentially unreliable data, improving operational safety and flexibility.
WHAT’S NEW
• controller/ratio_sync.go
– Deleted unused local structs (TestResult, DifferenceItem, SyncableChannel).
– Centralised config with constants: defaultTimeoutSeconds, defaultEndpoint, maxConcurrentFetches, ratioTypes.
– Replaced magic numbers; added semaphore-based concurrency limit and shared http.Client (with TLS & Expect-Continue timeouts).
– Added comprehensive error handling and context-aware logging via common.Log* helpers.
– Checked DB errors from GetChannelsByIds; early-return on failures or empty upstream list.
– Removed custom-channel support; logic now relies solely on ChannelIDs.
– Minor clean-ups: import grouping, string trimming, endpoint normalisation.
• dto/ratio_sync.go
– Simplified UpstreamRequest: dropped unused CustomChannels field.
WHY
These improvements harden the ratio-sync endpoint for production use by preventing silent failures, controlling resource usage, and making behaviour configurable and observable.
HOW
No business logic change—only structural refactor, logging, and safeguards—so existing API contracts (aside from removed custom_channels) remain intact.
