Security hardening, error handling, AI client refactoring, and test coverage#41
Conversation
Security:
- Fix OkHttp response body leaks in AI clients by using .use{} blocks
- All HTTP responses now properly closed in OpenAiCompatibleClient base
Error handling:
- Add Timber logging to silent catch blocks in EqualizerPreferencesRepository,
PlaylistViewModel, LyricsStateHolder, FileExplorerStateHolder,
DeviceCapabilitiesViewModel, PhoneDirectWatchTransferCoordinator
Refactoring:
- Extract OpenAiCompatibleClient base class from DeepSeek, Groq, Mistral,
GenericOpenAi clients (~600 lines of duplicated code removed)
- Extract ServerUrlUtils for shared URL normalization/validation logic
used by NavidromeCredentials and JellyfinCredentials
Tests:
- Add AiClientFactoryTest (all providers, blank key validation)
- Add OpenAiCompatibleClientTest (config, model filtering, token counting)
- Add CloudMusicUtilsTest (JSON parsing, artist name parsing)
- Add ServerUrlUtilsTest (URL normalization, validation, local network checks)

…layerHQ#2371 PR #41 refactored AI clients into OpenAiCompatibleClient base class. Upstream PixelPlayerHQ#2371 deleted separate clients entirely, unified into GenericOpenAiClient. Resolution: accept PixelPlayerHQ#2371's deletions, remove now-dead OpenAiCompatibleClient and its test, update AiClientFactoryTest to match new architecture.

📝 Info: GDriveStreamProxy auth check at line 164 and 189 is now dead code
Because getAuthHeader() now throws IllegalArgumentException via require() when the token is null/blank (GDriveApiService.kt:38), the checks at GDriveStreamProxy.kt:164 (authHeader.isBlank() || authHeader == "Bearer ") and GDriveStreamProxy.kt:189 are unreachable dead code. The exception will always propagate to the catch block at line 257 before these checks execute. This is the downstream impact of the bug reported in BUG-0001.

🔴 getAuthHeader() now throws instead of returning empty string, breaking GDriveStreamProxy graceful error handling
The getAuthHeader() method was changed to use require(!token.isNullOrBlank()) which throws IllegalArgumentException when no access token is set. However, GDriveStreamProxy at GDriveStreamProxy.kt:162-167 and GDriveStreamProxy.kt:188-191 relies on the old behavior of receiving "Bearer " and gracefully responding with HTTP 401. Now, the require throws before those checks execute. The exception is caught by the generic catch block at GDriveStreamProxy.kt:257, which only logs the error without sending a proper HTTP response to the media player. This means the player won't receive a clean 401 that could trigger re-authentication — it will likely get a connection error or 500 instead, breaking GDrive audio streaming when the token is expired or not yet set.
Prompt for agents
The getAuthHeader() method in GDriveApiService was changed from returning "Bearer " (with empty token) to throwing an IllegalArgumentException via require(). This breaks two callers in GDriveStreamProxy (lines 162 and 188) that check for blank/empty auth headers and respond with HTTP 401 to trigger re-authentication.
The fix needs to coordinate the change across both files:
Option A (recommended): Revert getAuthHeader() to return the value without require, keeping the graceful degradation that GDriveStreamProxy depends on. If you still want strict validation for the non-streaming callers (createFolder, executeGet), add a separate method or check hasToken() before calling those methods.
Option B: Keep the require() but update GDriveStreamProxy to call hasToken() before getAuthHeader() and handle the no-token case explicitly, both at line 162 and 188.
Files involved: GDriveApiService.kt (getAuthHeader), GDriveStreamProxy.kt (lines 162-167, 188-191).

📝 Info: NavBar corner radius parameter reordering is cosmetic, not a behavioral fix
The diff for NavBarCornerRadiusScreen.kt:344-352 reorders the named parameters of AbsoluteSmoothCornerShape. At first glance it looks like a bug fix (the old ordering mixed BL smoothness next to TL radius), but since Kotlin named parameters are resolved by name regardless of position, and all smoothness values are identical (60), the old and new code produce the exact same shape. This is purely a readability improvement.

📝 Info: Each OpenAiCompatibleClient subclass instantiates its own OkHttpClient
The base class OpenAiCompatibleClient creates a new OkHttpClient instance per subclass instance at OpenAiCompatibleClient.kt:48-52. Since each AI provider creates a separate client, this means multiple connection pools and thread pools exist in parallel. This was the same behavior before the refactoring (each old class had its own OkHttpClient), so it's not a regression. However, now that the code is unified, it would be straightforward to share a single injected OkHttpClient instance across all providers to reduce resource usage.

🚩 OpenRouter-specific headers only added for generateContent, not getAvailableModels/validateApiKey
The decorateRequest hook in GenericOpenAiClient.kt:18-24 adds OpenRouter-specific headers (HTTP-Referer, X-Title) but is only called from generateContent(). The getAvailableModels() and validateApiKey() methods in the base class don't call decorateRequest. This matches the pre-refactoring behavior (the old GenericOpenAiClient also only added those headers in generateContent), so it's not a regression. However, if OpenRouter requires these headers for all endpoints, this could cause model listing or key validation to fail for OpenRouter users.

📝 Info: Groq model filter lost whisper filtering that was previously in the old code
The old GroqAiClient filtered models with .filter { !it.contains("whisper") }. The new GroqAiClient.kt:15-16 preserves exactly the same filter. However, the old GenericOpenAiClient additionally filtered embed and tts models which the new GenericOpenAiClient.kt:26-29 also preserves. The refactoring correctly kept per-provider filter logic distinct via the filterModels override pattern. No behavior change.

🚩 Netty version change from 4.2.28 to 4.2.15 appears intentional per commit message
The libs.versions.toml changes netty from 4.2.28.Final to 4.2.15.Final. Numerically this looks like a downgrade, but the commit message says "Fix Netty version" suggesting 4.2.28 was incorrect (possibly a non-existent version). Unable to verify from the repository alone whether 4.2.28.Final exists as a published release.

📝 Info: Regex instances hoisted to companion object in LyricsRepositoryImpl reduces allocation overhead
Six regex patterns (MASH_UP_REGEX, DIACRITICS_REGEX, APOSTROPHE_REGEX, NON_ALNUM_REGEX, WHITESPACE_COLLAPSE_REGEX, LONG_LATIN_RUN_REGEX) at LyricsRepositoryImpl.kt:139-144 were moved from inline Regex(...) calls inside methods to companion object fields. This avoids recompiling the regex on every invocation of normalizeForMatch, timingVariantTokens, and looksLikeFlattenedWordByWordCache, which are called frequently during lyrics matching. Good performance improvement.
