feat(URL): Support seeking logs by timestamp via URL parameter (resolves #117).

[Henry8192]

Description

Closes #117.
Implements JSONL & CLPIR findNearestLogEventByTimestamp feature:

• JSONL implementation is located in src/services/decoders/JsonlDecoder/index.ts.
• CLPIR findNearestLogEventByTimestamp API is here. We use this API in src/services/decoders/ClpIrDecoder.ts.

Here's an example of searching log events with timestamp Mar 28 2023 04:01:18.594 GMT+0000:
localhost:3010/?filePath=http://localhost:3010/test/example.jsonl#timestamp=1679976078594

Here, the hash parameter #timestamp=1679976078594 is the unix timestamp of our target in miliseconds. This would trigger a search in log events with timestamp closest to 1679976078594. After the search is done, it would jump to that log event, and clear the #timestamp parameter in the URL.

Validation performed

Performed search with timestamp of 1679976078593, 1679976078594, 1679976078595 and 1679976078596 with example.jsonl.zip (please unzip it).

Summary by CodeRabbit

• New Features
  • Added support for navigating log events by timestamp, allowing users to jump directly to events closest to a specified time.
• Improvements
  • Enhanced URL handling to prioritise timestamp-based navigation over event number when loading logs.
  • Improved synchronisation and validation of URL parameters for log navigation and queries.
  • Refined parsing and default handling of URL hash and search parameters, including a new timestamp parameter.
  • Centralized and clarified URL hash parameter management with added bounds checking and error handling.
• Bug Fixes
  • Refined logic for updating UI state and URL parameters when changing pages or sharing permalinks.

overall structure looks really good

[junhaoliao]

@Henry8192 can we address the linter checks before we proceed further? If the ClpIrDecoder return error is the blocker, we can wait for y-scope/clp-ffi-js#42 to be merged first.

src/typings/decoders.ts (1)

102-119: Consider clarifying the return value for no-match cases.

The documentation should explicitly state what value is returned when no matching log event is found. Based on the past review discussion, it would be helpful to document whether it returns null or -1 in such cases.

     /**
      * Finds the log event, L, where if we assume:
      *
      * - the collection of log events is sorted in chronological order;
      * - and we insert a marker log event, M, with timestamp `timestamp` into the collection (if log
      *   events with timestamp `timestamp` already exist in the collection, M should be inserted
      *   after them).
      *
      * L is the event just before M, if M is not the first event in the collection; otherwise L is
      * the event just after M.
      *
      * NOTE: If the collection of log events isn't in chronological order, this method has undefined
      * behaviour.
      *
+     * @return The index of the log event L, or null if no matching log event is found.
      *
-     * @param timestamp
-     * @return The index of the log event L.
+     * @param timestamp The timestamp to search for.
      */

src/services/decoders/JsonlDecoder/index.ts (1)

125-144: Consider adding input validation and improving type safety.

The binary search implementation is efficient, but could benefit from some improvements:

1. Add validation for negative timestamps
2. Extract the log event access into a separate constant to improve readability and type safety

Apply this diff to improve the implementation:

 findNearestLogEventByTimestamp (timestamp: number): Nullable<number> {
+    if (timestamp < 0) {
+        return null;
+    }
     let low = 0;
     let high = this.#logEvents.length - 1;
     if (high < low) {
         return null;
     }

     while (low <= high) {
         const mid = Math.floor((low + high) / 2);
-        // eslint-disable-next-line @typescript-eslint/no-non-null-assertion
-        const midTimestamp = this.#logEvents[mid]!.timestamp.valueOf();
+        const midLogEvent = this.#logEvents[mid];
+        const midTimestamp = midLogEvent.timestamp.valueOf();
         if (midTimestamp <= timestamp) {
             low = mid + 1;
         } else {
             high = mid - 1;
         }
     }

     return high;
 }

src/contexts/UrlContextProvider.tsx (1)

208-219: Consider improving readability of the parameter array declaration.

The array declaration could be more readable by using proper line breaks and alignment.

Apply this diff to improve readability:

-    const numberHashParamNames = [HASH_PARAM_NAMES.LOG_EVENT_NUM,
-        HASH_PARAM_NAMES.TIMESTAMP];
+    const numberHashParamNames = [
+        HASH_PARAM_NAMES.LOG_EVENT_NUM,
+        HASH_PARAM_NAMES.TIMESTAMP,
+    ];

src/services/LogFileManager/index.ts (1)

434-462: Consider adding validation and improving error handling.

The cursor data handling for timestamps could benefit from some improvements:

1. Add validation for negative timestamps
2. Consider adding error handling for the case when no event is found

Apply this diff to improve the implementation:

     } else {
+        if (args.timestamp < 0) {
+            throw new Error("Timestamp cannot be negative");
+        }
         const eventIdx = this.#decoder.findNearestLogEventByTimestamp(args.timestamp);
         if (null !== eventIdx) {
             eventNum = eventIdx + 1;
+        } else {
+            throw new Error("No log event found for the given timestamp");
         }
     }

src/contexts/StateContextProvider.tsx (1)

488-498: Consider adding error handling for invalid timestamps.

The timestamp effect should handle invalid timestamp values gracefully.

Apply this diff to improve error handling:

     if (null === mainWorkerRef.current || null === timestamp) {
         return;
     }
 
+    if (timestamp < 0) {
+        console.error("Invalid timestamp value:", timestamp);
+        updateWindowUrlHashParams({timestamp: null});
+        return;
+    }
+
     loadPageByCursor(mainWorkerRef.current, {
         code: CURSOR_CODE.TIMESTAMP,
         args: {timestamp: timestamp},
     });
     updateWindowUrlHashParams({timestamp: null});

🔇 Additional comments (10)

src/typings/url.ts (1)

9-10: LGTM! The changes align well with the PR objectives.

The addition of the TIMESTAMP enum value and the timestamp property in UrlHashParams interface provides proper typing support for querying log events by timestamp via URL hash parameters.

Also applies to: 18-19

src/typings/logs.ts (1)

46-46: LGTM! The constant is properly defined using BigInt.

The use of BigInt for INVALID_TIMESTAMP_VALUE aligns with the timestamp handling in the codebase, particularly with the DecodeResult type that uses BigInt for timestamps.

src/typings/decoders.ts (1)

102-119: LGTM! The method is well-documented and properly typed.

The method signature and documentation provide clear guidance on the chronological order requirement and the marker log event concept.

src/services/decoders/ClpIrDecoder.ts (1)

80-82: LGTM! The implementation is clean and handles type conversion properly.

The method correctly converts the number timestamp to BigInt before passing it to the stream reader, maintaining consistency with the underlying implementation.

src/services/decoders/JsonlDecoder/index.ts (1)

238-256: LGTM! Timestamp type change improves precision.

The change from number to bigint for timestamp handling is a good improvement as it prevents potential precision loss when dealing with large timestamp values.

src/contexts/UrlContextProvider.tsx (1)

32-35: LGTM! Default state properly initialized.

The addition of HASH_PARAM_NAMES.TIMESTAMP to URL_HASH_PARAMS_DEFAULT with a null default value is consistent with the existing pattern.

src/contexts/StateContextProvider.tsx (3)

250-276: LGTM! Proper state management setup.

The addition of timestamp handling in the context and ref setup follows the established patterns.

---

464-468: LGTM! Consistent ref synchronization.

The useEffect hook for timestamp synchronization follows the same pattern as other ref synchronizations.

---

541-546: LGTM! Consistent cursor handling.

The addition of timestamp cursor handling in the file loading logic is consistent with the existing event number cursor handling.

package.json (1)

33-33: Dependency Version Bump for clp-ffi-js
The dependency version for clp-ffi-js has been updated from ^0.3.4 to ^0.3.5. This change supports the new timestamp handling features as outlined in the PR objectives. Please ensure that all modules relying on this dependency are tested against this updated version for compatibility.

[Henry8192]

Just woke up for a bug in find nearst log event by timestamp before I go to sleep again: if all log events' timestamps are larger than target timestamp, return high would overflow. Need to check that condition before the return.

Extract variable to preserve type-checking.

The non-null assertion disables type-checking for the entire line. Let's extract the log event into a variable first.

144-146: Define constant for magic number and improve corner case handling.

The magic number 0 is used for both comparison and return value. Let's define a constant and improve the corner case handling.

Apply this diff to improve readability and maintainability:

+
     findNearestLogEventByTimestamp (timestamp: number): Nullable<number> {
-        let low = 0;
+        let low = JsonlDecoder.#FIRST_INDEX;
         let high = this.#logEvents.length - 1;
         if (high < low) {
             return null;
         }
         // ... binary search implementation ...
         // corner case: all log events have timestamps >= timestamp
-        if (0 > high) {
-            return 0;
+        if (JsonlDecoder.#FIRST_INDEX > high) {
+            return JsonlDecoder.#FIRST_INDEX;
         }

---

128-130: Align with coding guidelines by using false == <expression>.

Per coding guidelines, prefer false == <expression> over !<expression>.

Apply this diff to align with coding guidelines:

-        if (high < low) {
+        if (false == (high >= low)) {
             return null;
         }

Learning: In the yscope-log-viewer codebase, when using Zustand stores in React components, the preferred pattern is to use `getState()` for static setters that never change (like `setLogEventNum`) to avoid unnecessary subscriptions, while using hooks for actions that do more than just setting values. All store state variables should be declared at the beginning of the component for consistency and clear dependency overview.

🔇 Additional comments (5)

src/stores/logFileStore.ts (1)

155-155: Good placement for query parameter synchronization.

The call to updateQueryHashParams() is appropriately placed after page data is updated and before the query starts, ensuring consistent state before query execution.

src/components/AppController.tsx (4)

30-67: Well-implemented function with proper bounds checking and clear documentation.

The function correctly checks if a log event is within the current page bounds before updating the URL, preventing unnecessary page reloads. The detailed comments explaining the type assertions add clarity to the logic.

---

130-149: Clean refactoring that centralizes cursor logic.

The refactored function effectively delegates cursor determination to getCursorFromHashParams and properly handles async page loading with appropriate error handling. Resetting isPrettified and timestamp to defaults prevents stale values.

---

156-185: Good practice: Explicitly resetting query parameters to defaults.

The function now properly resets all query-related URL hash parameters to their default values before synchronizing with the query store state, ensuring clean state management.

---

233-243: Correct implementation of timestamp-based cursor during initial load.

The code properly handles the timestamp parameter during initial file load, creating a timestamp-based cursor when a non-default timestamp is provided. The priority order (timestamp before logEventNum) aligns with the feature requirements.

src/stores/logFileStore.ts (2)

24-24: Good integration of URL hash parameter synchronization.

The import from the utility module maintains proper architectural boundaries.

---

155-155: Appropriate placement for query hash parameter synchronization.

The call to updateQueryHashParams() is correctly positioned after page data loading and before query execution, ensuring the query state is synchronized with URL parameters.

src/components/CentralContainer/Sidebar/SidebarTabs/SearchTabPanel/Result.tsx (2)

9-9: Good refactoring to centralized URL hash parameter management.

The import change aligns with the pattern of using utility functions for state synchronization rather than direct store manipulation.

---

44-46: Correct implementation of the new URL hash parameter pattern.

The sequence of updating URL hash parameters followed by calling updateViewHashParams() properly implements the centralized state synchronization approach.

src/components/StatusBar/index.tsx (2)

25-25: Good integration of centralized URL hash parameter management.

The import aligns with the refactoring pattern across the codebase.

---

55-58: Correct implementation of URL hash parameter synchronization.

The sequence of updating URL hash parameters and then calling updateViewHashParams() follows the established pattern. The use of !isPrettified aligns with the team's preference for the ! operator over the false == <expression> pattern.

src/components/Editor/index.tsx (3)

37-37: Good integration of URL hash parameter utilities.

The import supports the centralized URL hash parameter management pattern.

---

167-172: Correct implementation of prettify toggle with URL hash parameters.

The logic properly updates URL hash parameters and then synchronizes the view state using updateViewHashParams(). The use of !isPrettified aligns with the team's coding preferences.

---

274-275: Appropriate update to use simplified store setter.

The change from updateLogEventNum to setLogEventNum aligns with the store slice simplification where side effects are removed from state setters.

src/utils/url/index.ts (3)

28-28: Good addition of TIMESTAMP parameter for new navigation feature.

The default value of -1 is appropriate for indicating an invalid/unset timestamp.

---

165-195: Excellent refactoring to improve code organization.

The switch-case structure with proper type handling for numbers and fallback to defaults is much cleaner than the previous approach. The grouped boolean cases are well-organized.

---

216-216: Good simplification of comparison logic.

The direct comparison with default values is cleaner and more readable than using a helper function.

src/components/AppController.tsx (2)

17-17: LGTM!

Good refactoring to centralize the URL hash handling logic.

---

52-62: Correct implementation of timestamp prioritization.

The cursor logic correctly prioritizes timestamp over logEventNum, which aligns with the PR objectives for seeking logs by timestamp.

src/utils/url/urlHash.ts (3)

31-59: Well-implemented bounds checking with clear type safety.

The function correctly validates the log event number is within page bounds before updating the URL. The detailed comments explaining the type casting safety are excellent.

---

123-142: Clean implementation with proper async error handling.

The function correctly resets consumed parameters and handles async page loading errors appropriately.

---

150-178: Efficient query parameter tracking.

Good use of the ||= operator to track modifications across multiple parameters. The function correctly returns whether any query parameters were modified.

        console.log(ret)
        return ret;
    }

this.#streamReader.findNearestLogEventByTimestamp always returns the largest index.

@coderabbitai can you create an issue on this?

[Henry8192]

The return from clp-ffi-js doesn't look correct, but we cannot address this problem in this PR.

Steps to reproduce: Change findNearestLogEventByTimestamp code in ClpIrDecoder.ts to

    findNearestLogEventByTimestamp (timestamp: number): Nullable<number> {
        console.log(timestamp)
        const ret = this.#streamReader.findNearestLogEventByTimestamp(BigInt(timestamp));
        console.log(ret)
        return ret;
    }

this.#streamReader.findNearestLogEventByTimestamp always returns the largest index.

@hoophalab sorry, I cannot reproduce this error. The unix timestamp we are using is in milliseconds, did you input them in the correct way?

For example, for this log event (https://yscope.s3.us-east-2.amazonaws.com/sample-logs/yarn-ubuntu-resourcemanager-ip-172-31-17-135.log.1.clp.zst) on page 2 (page size 10000), there's 2015-03-23T09:43:32.001+00:00 on line 8. The corresponding timestamp is 1427103812001.

108-108: Use clamped log event number for state consistency.

The function uses clampedLogEventNum for cursor and URL updates but calls updateLogEventNum with the unclamped value, which could lead to inconsistent state.

-        updateLogEventNum(logEventNum);
+        updateLogEventNum(clampedLogEventNum);

---

102-106: Add timestamp validation for robust error handling.

The function doesn't validate that the timestamp is a valid positive number before creating the cursor, which could cause issues downstream.

 if (timestamp !== URL_HASH_PARAMS_DEFAULT.timestamp) {
+    // Validate timestamp is a positive number
+    if (timestamp <= 0) {
+        updateWindowUrlHashParams({timestamp: URL_HASH_PARAMS_DEFAULT.timestamp});
+        return null;
+    }
     return {
         code: CURSOR_CODE.TIMESTAMP,
         args: {timestamp: timestamp},
     };

Learning: In the yscope-log-viewer codebase, when using Zustand stores in React components, the preferred pattern is to use `getState()` for static setters that never change (like `setLogEventNum`) to avoid unnecessary subscriptions, while using hooks for actions that do more than just setting values. All store state variables should be declared at the beginning of the component for consistency and clear dependency overview.

165-195: Excellent refactoring of hash parameter parsing logic.

The switch-case structure significantly improves code maintainability and readability compared to the previous if-else chain. The explicit handling of number parsing with NaN checks and fallback to defaults is robust.

src/components/AppController.tsx (1)

232-242: Timestamp prioritization aligns with PR objectives.

The modification to prioritize timestamp over logEventNum in the initialization logic correctly implements the feature requirement for timestamp-based navigation.

@Henry8192 you are right, it seems that I used irv2 and forgot to set the timestamp key.

Learning: In the yscope-log-viewer codebase, when using Zustand stores in React components, the preferred pattern is to use `getState()` for static setters that never change (like `setLogEventNum`) to avoid unnecessary subscriptions, while using hooks for actions that do more than just setting values. All store state variables should be declared at the beginning of the component for consistency and clear dependency overview.

Learning: In `src/services/formatters/YScopeFormatter/FieldFormatters/TimestampFormatter.ts`, the `convertToDayjsTimestamp` function already includes error handling for invalid inputs, so wrapping it in try-catch in the `TimestampFormatter.formatField` method is unnecessary.

Learning: For the viewStore in the yscope-log-viewer project, it's more appropriate to suppress the max-lines-per-function ESLint rule than to split the store into slices due to the tight coupling and cohesive nature of its functions.

🔇 Additional comments (13)

src/stores/viewStore/createViewEventSlice.ts (1)

9-9: Good refactoring to centralize URL logic.

The extraction of updateUrlIfEventOnPage to a shared utility function follows the DRY principle and allows for better code reuse across the application.

src/utils/url.ts (7)

1-1: ESLint max-lines directive increased appropriately.

The increase in the max-lines limit is justified given the addition of new functionality for timestamp-based navigation.

---

10-13: Imports added for new URL update functionality.

The imports support the new updateUrlIfEventOnPage function that was extracted from the view store slice.

---

32-32: TIMESTAMP parameter added with appropriate default value.

The default value of -1 for timestamp is appropriate as it represents an invalid timestamp, clearly distinguishing it from valid Unix timestamps.

---

112-112: Improved parameter deletion logic.

The change from isEmptyOrFalsy to direct comparison against default constants is more explicit and maintainable.

Also applies to: 220-220

---

169-199: Well-structured parsing logic refactoring.

The switch-case structure is cleaner and more maintainable than the previous if-else chain. The TIMESTAMP parsing correctly handles invalid numbers by falling back to the default value.

---

383-383: Export added for new utility function.

The export is correctly added to make the function available to other modules.

---

336-372: Confirm extraction of updateUrlIfEventOnPage
The updateUrlIfEventOnPage implementation has been removed from src/stores/viewStore/createViewEventSlice.ts and is now correctly defined in src/utils/url.ts, then imported where needed. No further changes required.

src/components/AppController.tsx (5)

6-6: Imports updated appropriately for new functionality.

The import changes support the new timestamp-based navigation features and centralized URL utilities.

Also applies to: 8-8, 16-16, 20-21

---

88-107: Refactored view hash parameter handling looks correct.

The function correctly resets parameters to defaults before processing and uses the new cursor determination logic. The async error handling is appropriate.

---

115-117: Explicit URL parameter updates improve consistency.

The explicit updates to query-related hash parameters ensure URL synchronization, which addresses the TODO comment about removing empty parameters.

---

190-195: Timestamp prioritization in initial file loading is correct.

The logic correctly prioritizes timestamp over logEventNum when loading files from URL parameters, which aligns with the feature requirements.

---

60-78: Ignore incorrect inconsistency concern

The getCursorFromHashParams implementation in src/components/AppController.tsx (lines 60–78) consistently checks timestamp first, then logEventNum. The same prioritization appears in updateViewHashParams via its call to getCursorFromHashParams. There’s no structural inconsistency in the else if—it correctly handles the two cases in order.

Likely an incorrect or invalid review comment.
