Walkthrough

This pull request introduces a comprehensive refactoring of the weather data handling system in BirdNET-Go. The changes replace the existing OpenWeather-specific implementation with a more flexible, provider-agnostic weather service. A new weather package is created to support multiple weather providers (currently Yr.no and OpenWeather), with improved configuration management, icon handling, and data retrieval mechanisms. The modifications span configuration, data storage, HTTP handlers, and template rendering to create a more modular and extensible weather data integration.

Actionable comments posted: 4

🧹 Nitpick comments (15)
internal/weather/provider_openweather.go (1)

51-127: Consider a more granular retry approach or immediate resource cleanup.
The pattern of deferring resp.Body.Close() within the loop can accumulate multiple defers if multiple retries occur. Although these defers will eventually run, it is often considered clearer to close the response body within the same iteration before continuing. This approach avoids stacking multiple defers and clarifies resource-lifetime handling.

internal/weather/provider_yrno.go (1)

47-145: Return typed “no new data” errors to distinguish from actual failures.
If the response is 304 ("Not Modified"), the method returns a generic error. You may want a typed error (e.g., ErrNoNewData) to handle it differently upstream instead of logging it as an error internally.

+var ErrNoNewData = errors.New("no new data available")
...
if resp.StatusCode == http.StatusNotModified {
-    return nil, fmt.Errorf("no new data available")
+    return nil, ErrNoNewData
}
internal/weather/weather.go (3)

23-36: Consider doc comments for WeatherData fields.
This struct forms the core of weather data across providers. Adding Go doc comments clarifies the meaning and typical ranges of each field, improving maintainability for future contributors.


141-181: Graceful polling design.
The ticker-based loop with a configurable interval is straightforward and easy to maintain. For large scale usage, consider backoff strategies or separate concurrency controls if the weather API usage grows.


183-231: Consolidate debug logging.
The debug logging is verbose and scattered throughout the method. Consider using a structured logging approach or bundling messages into a single log entry to avoid spamming logs, especially in production.

internal/weather/providers.go (1)

13-17: Consider doc comments for provider structs.
Documenting YrNoProvider and OpenWeatherProvider clarifies their responsibilities, especially since both implement the Provider interface in distinct ways.

internal/httpcontroller/handlers/weather.go (1)

32-36: Add a fallback for incomplete sun event data.
If suncalc.SunEventTimes is missing some fields or a time is unexpectedly zero-value, ensure CalculateTimeOfDay can handle it gracefully.

internal/weather/icon_codes.go (2)

45-57: Consider clarifying day/night in descriptions.

These human-readable descriptions do not differentiate between day and night. If your application or UI needs distinct textual clues (e.g., "Clear Sky (Night)"), expanding these descriptions might improve clarity.


59-72: Add logging on fallback icon code usage.

Returning "01" as a fallback ensures that unmapped codes do not break the application. However, to ease troubleshooting, consider logging a debug or warning message to flag unexpected provider codes.

 func GetStandardIconCode(code string, provider string) IconCode {
     switch provider {
         ...
     }
-    return "01" // default to clear sky if no mapping found
+    log.Printf("Warning: Unmapped %s code '%s', defaulting to '01'", provider, code)
+    return "01"
 }
internal/httpcontroller/template_functions.go (1)

51-51: Ensure safe handling of missing weather data.

The new "weatherDescription" template function is valuable. Consider explicitly handling cases where the weather data might be unavailable or incomplete, and return a default placeholder string or an empty string to avoid confusion in the UI.

internal/conf/defaults.go (1)

101-120: Clean up commented-out legacy code.

The old OpenWeather block is commented out. If it’s definitively deprecated, removing it entirely would reduce confusion. If you plan to reintroduce it later, adding a clarifying comment about its future use would be helpful. Also, using "yrno" as the default provider with a 60-minute poll interval appears reasonable.

internal/conf/validate.go (1)

281-288: Add checks for valid provider names (if relevant).

validateWeatherSettings diligently enforces a minimum PollInterval. If you expect only certain supported providers (e.g., yrno, openweather), you might also validate that settings.Provider is recognized. This can help catch typos or invalid configurations early.

 func validateWeatherSettings(settings *WeatherSettings) error {
+    validProviders := []string{"yrno", "openweather"}
+    providerIsValid := false
+    for _, p := range validProviders {
+        if settings.Provider == p {
+            providerIsValid = true
+            break
+        }
+    }
+    if !providerIsValid {
+        return fmt.Errorf("invalid weather provider: %s", settings.Provider)
+    }

     if settings.PollInterval < 15 {
         return fmt.Errorf("weather poll interval must be at least 15 minutes, got %d", settings.PollInterval)
     }
     return nil
 }
internal/weather/icons.go (1)

20-58: Comprehensive icon mapping
The definition of SVG icons for different conditions and times of day is thorough. Good separation of concerns, but consider extracting the repetitive <svg> code into a shared library if it grows too large.

internal/conf/config.go (1)

102-102: Clarify rationale for legacy support.

The comment indicates that Enabled is for legacy support. Consider adding a note or date on when to remove or retire this field if it is truly temporary.

views/settings/integrationSettings.html (1)

338-468: Dynamic weather settings panel is well-structured.

The reactive Alpine.js block for weather settings effectively toggles provider options. This design makes it easy to introduce new weather providers in the future. Ensure the pollInterval value has sufficient validation server-side to prevent excessively frequent polling or unintentional resource usage.

[error] 92-92: trailing spaces

(trailing-spaces)

🔇 Additional comments (36)
internal/weather/provider_yrno.go (1)

18-45: Validate presence of expected fields in Yr.no response.
Similar to OpenWeather, Yr.no generally provides a well-structured response, but the code assumes presence of Timeseries[0].Data.Next1Hours. Consider verifying that len(Properties.Timeseries) > 0 and Next1Hours is not nil to avoid potential runtime panics if the API response changes or is incomplete.

internal/weather/weather.go (3)

63-82: Ensure fallback logic matches PR summary.
The PR summary mentions an automatic fallback to Yr.no if no provider is specified, but here you explicitly error out when the provider doesn't match "yrno" or "openweather." Confirm that upstream code always sets a valid provider or add a fallback case.


84-129: Validate dailyEvents.ID before creating HourlyWeather records.
While it’s presumably guaranteed that s.db.SaveDailyEvents sets dailyEvents.ID, you might add a quick check to confirm dailyEvents.ID != 0 if that’s relevant to your DB constraints. Failing early can prevent unexpected foreign key issues.


130-139: Good practice on fundamental validation.
Basic checks for impossible weather conditions (e.g., temperature below absolute zero) are helpful to catch data errors.

internal/weather/providers.go (2)

3-6: Explicitly reference the YrNoProvider struct usage.
This factory approach is clean. If YrNoProvider needs additional fields later (e.g., caching or credentials), ensure you handle them in NewYrNoProvider.


8-11: Parallel structure for OpenWeather.
Similarly, NewOpenWeatherProvider adheres well to the same factory pattern, making it easy to add more providers in the future.

internal/httpcontroller/handlers/weather.go (2)

12-23: Caution with HTML generation.
Returning template.HTML can be safe if icons are strictly sanitized and controlled. Otherwise, consider escaping or validating to prevent XSS.


42-52: Consistent naming for weather codes.
Here we strip the suffix and fallback to the first two characters. Confirm the same approach is used across all icon or description lookups so that everything remains uniform.

internal/weather/icon_codes.go (2)

1-4: Excellent introduction and domain-specific naming.

The package declaration, documentation comment, and IconCode type make the file purpose clear. It's a good practice to include a brief explanation regarding the rationale behind standardizing icon codes (e.g., to streamline template rendering or front-end logic).


23-43: Provider-specific mappings look good.

The OpenWeatherToIcon map aligns with commonly used codes. No immediate issues are apparent, but it might be beneficial to confirm that all OpenWeather codes are covered or at least log any unmapped codes for better debugging.

internal/conf/validate.go (1)

65-69: Weather validation seamlessly integrated.

This new step in ValidateSettings ensures that weather-specific settings do not slip past validation. Just confirm that calling validateWeatherSettings is sufficient for all possible providers (e.g., if a new provider is introduced later, you can expand the validation logic).

internal/analysis/realtime.go (2)

23-23: Imports aligned with new weather integration
No concerns here: the addition of the weather package import is consistent with the new architecture.


147-147: Flexible weather provider check
Great job ensuring the provider can be toggled dynamically by comparing against "none". This is a clean replacement for the older OpenWeather checks.

internal/httpcontroller/handlers/detections.go (4)

15-15: New weather package import
This import is consistent with the updated module approach. No issues.


34-34: Refactor to use TimeOfDay from weather package
Switching from a local type to weather.TimeOfDay is a clean approach to centralizing code around the new weather structures.


87-88: User-facing weather enablement check
Nicely replaces the old approach. The variable name weatherEnabled clarifies that we only proceed if a valid provider is configured.


235-235: Consistent weather provider check in helper method
Thanks for ensuring consistency in the addWeatherAndTimeOfDay function. This helps reduce conditional confusion.

internal/weather/icons.go (8)

1-2: New package introduction
The new weather package design is neat; it's modular and helps clarify weather-related logic.


10-18: TimeOfDay enum
Defining a clear enum for time-of-day states improves readability and helps avoid magic constants. Good job.


59-65: TimeOfDay icons
These icons nicely mirror the approach used for actual weather conditions. This cohesive design fosters consistency across the UI.


67-78: GetWeatherIcon
Great fallback logic returning a default icon if a specific time-of-day icon isn't found. Very user-friendly approach.


80-86: GetIconDescription
Straightforward, with a clear "Unknown" fallback. This is good for future-proofing.


88-94: GetTimeOfDayIcon
Same fallback logic as GetWeatherIcon. Consistency is key. Good job.


96-110: CalculateTimeOfDay
Nice usage of sun event boundaries to define the time of day. The logic is both clear and functionally sound. No concerns.


112-126: StringToTimeOfDay
Straightforward conversion function. Returning Day by default is reasonable.

internal/datastore/interfaces.go (5)

408-414: Upsert approach for daily events
Switching to FirstOrCreate with Assign helps reduce complexity. The error handling is also improved.


431-433: Hourly weather validation
It's good to prevent zero-time data from polluting the database. Clear and direct error message.


435-443: Upsert for hourly weather
Same improvement pattern as daily events. Brief, no-nonsense approach.


451-457: Sorted query for hourly weather
Ascending order ensures consistent retrieval. Logged error is concise and meaningful.


466-474: Graceful handling for LatestHourlyWeather
Covers both record-not-found and generic error cases. Nicely done.

internal/conf/config.go (4)

92-99: Good struct organization for weather settings.

Defining a separate WeatherSettings struct consolidates weather-related configuration cleanly. The documentation string on line 92 is helpful, though consider reiterating that PollInterval is in minutes.


158-158: YAML ignore annotation looks fine.

Ignoring OpenWeather in YAML is appropriate to avoid conflicting with the new WeatherSettings approach. Code is consistent with the legacy conversation in line 102.


165-165: Clear addition for weather configuration.

Adding Weather WeatherSettings in RealtimeSettings helps unify real-time processing with the new weather structure.


556-569: Logical fallback for weather settings.

The GetWeatherSettings method checks the new Weather.Provider first, then falls back to OpenWeather if enabled, otherwise defaults to "yrno." This ensures backward compatibility. If disabling weather is needed, ensure "none" is set to avoid the Yr.no fallback.

Would you like a verification script that checks for references to "none" usage in the codebase to confirm correct handling of disabled weather?

internal/conf/config.yaml (1)

89-97: Implementation of new weather section is consistent with the refactor.

The weather subsection with provider, pollinterval, debug, and nested openweather fields centralizes configuration neatly. The default choice of Yr.no matches the refactor’s stated intent.

💡 Codebase verification

Direct access to weatherData.Weather[0] could cause panic

The code directly accesses weatherData.Weather[0] without checking if the array is empty, which could lead to a panic. The OpenWeather API documentation typically guarantees at least one weather condition, but it's better to be defensive in our code. The current implementation in FetchWeather method needs bounds checking before accessing the array.

  • internal/weather/provider_openweather.go: Add bounds checking before accessing weatherData.Weather[0] in the return statement (around line 127-128).

The suggested fix in the review comment is appropriate, though I would modify it slightly to match the current codebase structure:

+ // Default values in case weather array is empty
+ description := "N/A"
+ icon := string(GetStandardIconCode("01d", "openweather")) // default to clear sky
+ 
+ if len(weatherData.Weather) > 0 {
+     description = weatherData.Weather[0].Description
+     icon = string(GetStandardIconCode(weatherData.Weather[0].Icon, "openweather"))
+ }

  return &WeatherData{
      // ... other fields ...
-     Description: weatherData.Weather[0].Description,
-     Icon:        string(GetStandardIconCode(weatherData.Weather[0].Icon, "openweather")),
+     Description: description,
+     Icon:        icon,
  }, nil
🔗 Analysis chain

Validate or document assumptions about weatherData.Weather array.
By design, OpenWeather often includes at least one weather entry, but there's no explicit check guarding against the case where weatherData.Weather could be empty. If the API unexpectedly returns an empty array, referencing weatherData.Weather[0] could cause an out-of-bounds panic.

A possible defensive fix:

-if len(weatherData.Weather) > 0 {
-    description = weatherData.Weather[0].Description
-    icon = GetStandardIconCode(weatherData.Weather[0].Icon, "openweather")
-}
+var description string
+var iconCode string
+if len(weatherData.Weather) > 0 {
+    description = weatherData.Weather[0].Description
+    iconCode = weatherData.Weather[0].Icon
+} else {
+    description = "N/A"
+    iconCode = "01d" // A sensible default or fallback
+}

Let me verify the concern by searching for the usage of weatherData.Weather array in the codebase.


Let me check the implementation of the OpenWeather provider to see the full context of how the response is handled.

🛠️ Refactor suggestion

Check for missing nighttime entries.

While Yr.no symbol codes for daytime are covered (e.g., partlycloudy_day), the corresponding nighttime variant (partlycloudy_night) is absent. If Yr.no provides a distinct code for that condition, consider adding it for completeness.

💡 Codebase verification

Weather service initialization lacks resilience mechanisms

Based on the code analysis, the concern about lack of retry logic is valid. The findings show:

  • The weather service initialization is a one-time attempt with no retry mechanism
  • Other services in the codebase (FFmpeg, Wikipedia, database) implement retry/backoff patterns for resilience
  • The weather service polling continues indefinitely once started, but if the initial setup fails, the service never recovers

Key locations that could benefit from retry logic:

  • internal/analysis/realtime.go: Add retry logic around weather.NewService() initialization
  • internal/weather/weather.go: Consider implementing backoff pattern similar to other services
🔗 Analysis chain

Successful transition to the new weather service
The code creates and starts the weather service with proper error handling. However, watch out for potential specific error types that might require a retry or a fallback approach. If initialization fails once, the service is never retried.

As a follow-up, consider exploring whether a limited retry logic or fallback is appropriate here to handle transient network/configuration issues.


Let me gather more information about the weather service implementation to better understand the initialization and error handling.


Let me check one more aspect about the weather service polling implementation.

⚠️ Potential issue

Remove trailing spaces.

A static analysis tool (yamllint) flags trailing spaces here. Strip any extra whitespace to maintain YAML cleanliness.
