Fix: Address potential bugs and improve error handling

Open PeterDaveHello opened this issue 5 months ago • 8 comments

User description

It's a large patch, and I'm unsure if we can get it merged. It's generated by Google's Jules Agent, which serves as a trial run and test lab. We can also review the feedback from other agents.

Jule's commit message:

This commit includes the following changes:

  • In src/background/index.mjs:

    • Ensured that port.proxy.postMessage({ session }) is called in executeApi even if port.proxy already exists, to prevent requests from not being sent to the ChatGPT tab.
    • Added comprehensive try...catch blocks and detailed logging for better error diagnosis and stability.
    • Added 'blocking' to onBeforeSendHeaders listener options as it modifies request headers.

  • In src/content-script/index.jsx:

    • Refactored prepareForForegroundRequests to manageChatGptTabState to ensure the port listener for ChatGPT Web models is dynamically and correctly (re-)registered when you change model configurations.
    • Added comprehensive try...catch blocks and detailed logging throughout the script to improve robustness and debuggability.

These changes aim to improve the overall stability and reliability of the extension. Manual testing is recommended to verify all scenarios, aided by the new logging.

GitHub Copilot's summary:

This pull request enhances logging and error handling in the src/background/index.mjs file to improve debugging and reliability. Key changes include adding detailed debug and error logs, handling potential exceptions in asynchronous operations, and improving the robustness of listener callbacks.

Enhanced Logging:

  • Added extensive console.debug statements to provide detailed insights into function calls, message handling, and API usage, including model-specific logs in executeApi and message type logs in Browser.runtime.onMessage.addListener. [1] [2] [3]
  • Improved logging for onBeforeRequest and onBeforeSendHeaders listeners to capture header modifications and request details.

Error Handling Improvements:

  • Wrapped critical operations in try-catch blocks to prevent runtime errors from impacting the application, including in listener callbacks and asynchronous API calls. Errors are logged with detailed context for easier debugging. [1] [2] [3] [4]
  • Enhanced error responses for specific operations, such as returning structured error objects in the FETCH message handler.

Reliability Enhancements:

  • Added reconnection logic in setPortProxy to handle proxy tab disconnections gracefully, ensuring the application can recover from unexpected disconnects.
  • Improved robustness of Browser.tabs.onUpdated listener by checking for valid URLs before performing side panel updates.

Code Organization:

  • Consolidated error handling in initialization functions (registerPortListener, registerCommands, refreshMenu) to ensure proper logging and fallback behavior during setup.

    54-74: Well-structured configuration constants.

    The reconnect configuration and sensitive keywords list are well-designed. The exponential backoff strategy with a maximum of 5 attempts is reasonable, and the sensitive keywords list comprehensively covers common patterns for API keys and authentication data.

    76-133: Excellent sensitive data redaction utility.

    This recursive redaction function is well-implemented with proper safeguards:

    • Circular reference detection using WeakSet
    • Maximum depth protection against infinite recursion
    • Case-insensitive keyword matching
    • Handles both arrays and objects appropriately

    The comprehensive approach ensures sensitive data is properly redacted before logging.

    135-259: Excellent refactoring addresses previous concerns.

    The setPortProxy function has been significantly improved:

    • ✅ Proper cleanup of old listeners before establishing new connections
    • ✅ Exponential backoff with maximum retry attempts (addresses infinite loop concerns)
    • ✅ Comprehensive error handling with detailed logging
    • ✅ Graceful cleanup on port disconnection

    This implementation effectively resolves the listener leak and infinite reconnection issues raised in previous reviews.

    261-418: Comprehensive improvements to API execution.

    The executeApi function has been significantly enhanced:

    • ✅ Detailed debug logging with sensitive data redaction
    • ✅ Robust error handling with user-friendly error messages
    • ✅ Enhanced ChatGPT Web Model proxy handling with reconnection logic
    • ✅ Comprehensive model type support with consistent logging
    • ✅ Graceful fallback mechanisms for failed connections

    The proxy reconnection logic in the ChatGPT Web Model section provides excellent resilience for handling connection failures.

    420-564: Enhanced message listener with comprehensive logging and error handling.

    The runtime message listener improvements provide:

    • ✅ Detailed logging for each message type processed
    • ✅ Comprehensive try-catch error handling
    • ✅ Structured error responses for FETCH operations
    • ✅ Proper error logging and fallback behavior
    • ✅ Consistent handling of unknown message types

    The enhanced error handling ensures robust message processing across all supported message types.

    566-647: Robust web request listener improvements.

    The web request listeners have been enhanced with:

    • ✅ Comprehensive try-catch error handling to prevent listener crashes
    • ✅ Detailed debug logging for request processing visibility
    • ✅ Safe header modification with proper null checks
    • ✅ Appropriate manifest version handling for blocking parameter
    • ✅ Graceful error recovery returning original headers on failure

    These improvements ensure stable web request processing even when unexpected errors occur.

    648-706: Excellent browser compatibility and error handling.

    The tabs.onUpdated listener demonstrates robust implementation:

    • ✅ Comprehensive error handling with nested try-catch blocks
    • ✅ Browser compatibility with fallback from Browser.sidePanel to chrome.sidePanel
    • ✅ Proper ESLint handling for chrome global usage
    • ✅ Detailed logging for debugging and monitoring
    • ✅ Smart validation to skip processing when appropriate

    The fallback mechanism ensures the extension works across different browser environments while maintaining proper error handling.

    708-740: Robust initialization with proper error handling.

    The initialization sections have been improved with:

    • ✅ Try-catch blocks around each initialization step
    • ✅ Clear success and error logging for debugging
    • ✅ Graceful handling of individual component failures
    • ✅ Non-blocking error handling that allows other components to initialize

    This ensures the extension remains functional even if individual components fail during initialization.

    PR Reviewer Guide 🔍

    Here are some key observations to aid the review process:

    ⏱️ Estimated effort to review: 4 🔵🔵🔵🔵⚪
    🧪 No relevant tests
    🔒 Security concerns

    Sensitive information exposure:
    The code previously had a commented out line that would log the access token (line 613). While it's currently commented out with a warning, the presence of this code suggests a risk of accidentally exposing sensitive tokens in logs. Additionally, the code handles various authentication tokens (ChatGPT, Claude, Kimi) and should ensure these are never logged or exposed, even in debug statements.

    ⚡ Recommended focus areas for review

    Reconnection Logic

    The reconnection logic in setPortProxy may cause an infinite loop if the proxy tab consistently fails to connect. There's no retry limit or backoff strategy.

     
    console.warn(`[background] Proxy tab ${proxyTabId} disconnected. Attempting to reconnect.`)
port.proxy = null // Clear the old proxy
// Potentially add a delay or retry limit here
setPortProxy(port, proxyTabId) // Reconnect
    Promise Rejection

    The Promise for waiting for Claude session key has a timeout but the rejection might not be properly handled in all code paths, potentially causing hanging operations.

     
      setTimeout(() => {
      clearInterval(timer);
      if (!claudeSession) {
          console.warn("[content] Timed out waiting for Claude session key.");
          reject(new Error("Timed out waiting for Claude session key."));
      }
  }, 30000); // 30 second timeout
}).catch(err => { // Catch rejection from the Promise itself (e.g. timeout)
  console.error("[content] Failed to get Claude session key for jump back notification:", err);
  // Do not proceed to render if session key is critical and not found
  return;
});
    Duplicate Code

    Similar timeout and polling logic is duplicated between Claude and Kimi authentication flows. This could be refactored into a shared utility function.

     
        await new Promise((resolve, reject) => {
      const timer = setInterval(async () => {
        try {
          claudeSession = await getClaudeSessionKey()
          if (claudeSession) {
            clearInterval(timer)
            console.log('[content] Claude session key found after waiting.')
            resolve()
          }
        } catch (err) {
          // This inner catch is for getClaudeSessionKey failing during setInterval
          console.error('[content] Error polling for Claude session key:', err)
          // Optionally, clearInterval and reject if it's a persistent issue.
        }
      }, 500)
      // Timeout for waiting
      setTimeout(() => {
          clearInterval(timer);

              console.warn("[content] Timed out waiting for Claude session key.");
              reject(new Error("Timed out waiting for Claude session key."));
          }
      }, 30000); // 30 second timeout
    }).catch(err => { // Catch rejection from the Promise itself (e.g. timeout)
      console.error("[content] Failed to get Claude session key for jump back notification:", err);
      // Do not proceed to render if session key is critical and not found
      return;
    });

    Handle array form values

    The code assumes that details.requestBody.formData[k] is a single value, but it
    could be an array of values. When appending form data, you should handle the
    case where the value is an array by iterating through each value.

    src/background/index.mjs [556-560]

     if (details.requestBody?.formData) { // Optional chaining
   for (const k in details.requestBody.formData) {

    Why: Valid improvement as formData values can be arrays according to the Chrome extension API. The suggestion properly handles this edge case.

    Handle undefined array elements

    The function doesn't handle the case where an array element is undefined. This
    could cause issues when processing arrays with sparse elements or undefined
    values. Add a specific check for undefined values to handle them properly.

    src/background/index.mjs [89-108]

     if (Array.isArray(obj)) {
   const redactedArray = [];
   for (let i = 0; i < obj.length; i++) {

    Why: The current code already handles undefined values correctly in the else branch. Adding explicit undefined handling would improve code clarity but is not necessary.

    		Low
    Fix race condition

    The error handling for Claude session key polling has a potential race
    condition. If the error occurs after promiseSettled has been set to true
    elsewhere but before this check runs, it will incorrectly set promiseSettled

    Remove development comment

    There's a comment "Example error check" left in the production code which
    suggests this error handling might be incomplete or was meant to be revised.
    Remove the comment and ensure the error conditions are properly defined for
    production use.

    Possible issue
    Handle special object types

    The redaction function doesn't handle primitive objects like Date, RegExp, or
    Map/Set, which could lead to errors when logging. These objects are typeof
    'object' but need special handling to avoid errors when iterating through their
    properties.

     function redactSensitiveFields(obj, recursionDepth = 0, maxDepth = 5, seen = new WeakSet()) {
   if (recursionDepth > maxDepth) {
     return 'REDACTED_TOO_DEEP';
   }

    The interval continues running indefinitely if no session key is found and no

    The function doesn't properly handle sensitive values in arrays. When iterating
    through object keys, array indices are converted to strings, but the function
    doesn't check array values directly. This could lead to sensitive data leakage
    when redacting arrays containing sensitive strings or objects.

    still connected before attempting to send the error message.

    Improve login button detection

    The code uses a fixed selector to find the login button by its text content
    '立即登录', but this approach is brittle and may fail if the UI changes or is
    localized. Use a more reliable selector or add a fallback mechanism.

    src/content-script/index.jsx [702-717]

     if (location.hostname === 'kimi.moonshot.cn') {
   console.debug('[content] On kimi.moonshot.cn, checking login status.')

    ✅ Improve HTTP error handling
    Suggestion Impact:The commit implemented the suggestion by adding a check for response.ok and including the ok property in the returned object. The implementation is slightly different from the suggestion but achieves the same goal.

               statusText: response.statusText,
               headers: Object.fromEntries(response.headers),

    The fetch operation doesn't handle non-network errors properly. If the response
    is received but has an error status code (e.g., 404, 500), it will still be
    treated as a success. Add status code checking to properly handle HTTP error
    responses.

    ✅ Prevent infinite polling loops
    Suggestion Impact:The commit implemented a commented-out example of the suggested error handling pattern. While not directly implementing the suggestion, it shows the developer acknowledged the issue and provided a template for how to handle specific errors to prevent infinite polling.

    code diff:

    +                // Example for Qodo: Stop on specific error
+                // if (err.message.includes('NetworkError') && !promiseSettled) {

+                //   reject(new Error(`Failed to get Claude session key: ${err.message}`));
+                // }

    The polling interval doesn't handle errors properly. If an exception occurs
    during getClaudeSessionKey(), the interval continues running indefinitely
    without resolving or rejecting the promise. Add error handling to prevent
    infinite polling on persistent errors.

    src/content-script/index.jsx [664-683]

     let timerId = setInterval(async () => {
   if (promiseSettled) {
     console.warn('[content] Promise already settled but Claude interval still running. This indicates a potential cleanup issue.');

     return
   }

    references) will cause postMessage to throw errors. Add a try-catch block to
    handle potential serialization errors.

    silently failing.

    Why: The existing_code doesn't match the actual implementation in the diff. The code already has proper .catch() error handling, making this suggestion less relevant.

    Detect encoded sensitive data

    The redaction function doesn't handle Base64 encoded secrets or API keys. Add
    detection for common Base64 patterns to prevent leaking sensitive information in
    logs that might be encoded rather than in plain text.

    src/background/index.mjs [60-69]

     const SENSITIVE_KEYWORDS = [
   'apikey',
   'token',
   'secret',
   'password',
   'kimimoonshotrefreshtoken',
   'auth',
   'key',
   'credential',
 ];
 
+const BASE64_PATTERNS = [
+  /^(?:[A-Za-z0-9+/]{4})*(?:[A-Za-z0-9+/]{2}==|[A-Za-z0-9+/]{3}=)?$/,
+  /^[A-Za-z0-9_-]{21,22}$/,  // URL-safe base64 without padding
+];
+

    __

    Why: Just adding BASE64_PATTERNS without integrating them into the redactSensitiveFields function provides no benefit. The improved code doesn't show how these patterns would be used.

    ✅ Fix potential null reference
    Suggestion Impact:The commit implemented the suggestion by adding a check for headers[i] existence before accessing its properties, but with a slightly different implementation approach. Instead of adding the check to each condition, the code was restructured to wrap all header operations in a single if(headers[i]) check.

    code diff:

    -          const headerNameLower = headers[i]?.name?.toLowerCase(); // Apply optional chaining
-          if (headerNameLower === 'origin') {
-            headers[i].value = 'https://www.bing.com'
-            modified = true
-          } else if (headerNameLower === 'referer') {
-            headers[i].value = 'https://www.bing.com/search?q=Bing+AI&showconv=1&FORM=hpcodx'
-            modified = true
+          if (headers[i]) {
+            const headerNameLower = headers[i].name?.toLowerCase();
+            if (headerNameLower === 'origin') {
+              headers[i].value = 'https://www.bing.com'
+              modified = true
+            } else if (headerNameLower === 'referer') {
+              headers[i].value = 'https://www.bing.com/search?q=Bing+AI&showconv=1&FORM=hpcodx'
+              modified = true
+            }
           }

    After using optional chaining for headers[i]?.name, you should verify that
    headers[i] exists before attempting to modify its value property. Otherwise, if
    a header entry is undefined but has a name property that matches, the code will
    throw an error when trying to set the value.

    src/background/index.mjs [543-550]

     const headerNameLower = headers[i]?.name?.toLowerCase(); // Apply optional chaining
-if (headerNameLower === 'origin') {
+if (headers[i] && headerNameLower === 'origin') {
   headers[i].value = 'https://www.bing.com'
   modified = true
-} else if (headerNameLower === 'referer') {
+} else if (headers[i] && headerNameLower === 'referer') {
   headers[i].value = 'https://www.bing.com/search?q=Bing+AI&showconv=1&FORM=hpcodx'
   modified = true
 }

    Why: This is a valid bug fix - using optional chaining on headers[i]?.name but not checking if headers[i] exists before setting its value property could cause runtime errors.

    ✅ Enhance sensitive data detection
    Suggestion Impact:The commit implemented exactly the suggested enhancement by adding the three recommended keywords ('auth', 'key', 'credential') to the SENSITIVE_KEYWORDS array, improving the detection of sensitive information in the application.

    code diff:

     const SENSITIVE_KEYWORDS = [
-  'apikey', // Covers apiKey, customApiKey, claudeApiKey, etc.
-  'token',  // Covers accessToken, refreshToken, etc.
+  'apikey',
+  'token',
   'secret',
   'password',
   'kimimoonshotrefreshtoken',
+  'auth',
+  'key',
+  'credential',
 ];

    The SENSITIVE_KEYWORDS array should include more comprehensive patterns to catch
    all potential sensitive information. Currently, it might miss some common
    sensitive data patterns like 'auth', 'key', 'credential', etc.

    src/background/index.mjs [60-66]

     const SENSITIVE_KEYWORDS = [
   'apikey', // Covers apiKey, customApiKey, claudeApiKey, etc.
   'token',  // Covers accessToken, refreshToken, etc.
   'secret',
   'password',
   'kimimoonshotrefreshtoken',
+  'auth',   // Covers authorization, oauth, etc.
+  'key',    // Catches generic keys
+  'credential',
 ];

    Why: Adding more comprehensive keywords like auth, key, and credential would improve the security redaction function, though the current implementation already covers the most common patterns.

    ✅ Improve cross-browser compatibility
    Suggestion Impact:The commit implemented a robust fallback mechanism for the Browser.sidePanel API by adding chrome.sidePanel as a fallback option, along with better error handling and checking if functions exist before calling them.

    code diff:

       Browser.tabs.onUpdated.addListener(async (tabId, info, tab) => {
+    const outerTryCatchError = (error) => { // Renamed to avoid conflict with inner error
+      console.error('[background] Error in tabs.onUpdated listener callback (outer):', error, tabId, info);
+    };
     try {
-      // Refined condition: Ensure URL exists and tab loading is complete.
       if (!tab.url || (info.status && info.status !== 'complete')) {
         console.debug(
           `[background] Skipping side panel update for tabId: ${tabId}. Tab URL: ${tab.url}, Info Status: ${info.status}`,
-        )
-        return
+        );
+        return;
       }
       console.debug(
         `[background] tabs.onUpdated event for tabId: ${tabId}, status: ${info.status}, url: ${tab.url}. Proceeding with side panel update.`,
-      )
-      // Use Browser.sidePanel from webextension-polyfill for consistency and cross-browser compatibility
-      if (Browser.sidePanel) {
-        await Browser.sidePanel.setOptions({
-          tabId,
-          pat...
