71-75: Consider adding O_TRUNC flag for file creationWhile the current implementation works correctly, consider adding the
O_TRUNCflag when opening the file to explicitly indicate that the file should be truncated if it exists. This makes the behavior more explicit.- exporter.outputFile, err = os.OpenFile(exporter.options.File, os.O_WRONLY|os.O_CREATE, 0644) + exporter.outputFile, err = os.OpenFile(exporter.options.File, os.O_WRONLY|os.O_CREATE|os.O_TRUNC, 0644)

89-89: LGTM! Change correctly implements JSONL format
The modification to append only a newline character (\n) instead of comma+newline properly aligns with the JSON Lines specification, which requires each JSON object to be on its own line without trailing commas.
Let's verify the output format:
✅ Verification successful
Let's gather more information by checking the test files to verify the JSONL export functionality:
Let's verify the implementation by checking the WriteRows method:
Based on the code inspection, I can now provide a final response about the JSONL format change:
LGTM! The JSONL format implementation is correct
The implementation in WriteRows() properly handles JSONL format by:
- Converting each record to JSON using
json.Marshal() - Appending only a newline character (
\n) after each JSON object - Writing each line sequentially to the file
This aligns with the JSONL (JSON Lines) specification which requires:
- One complete JSON object per line
- No trailing commas between objects
- Lines separated by newline characters
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Verify JSONL output format compliance
# Expected: Each line should be a valid JSON object without trailing commas
# Search for any test files that might contain sample JSONL output
fd -e jsonl -x sh -c 'echo "=== {} ==="; cat {} | jq -c "." || echo "Invalid JSONL format"'
# Also check if there are any tests validating the output format
rg -A 5 "TestJSONLExporter|jsonl.*export"
Length of output: 3479
Script:
#!/bin/bash
# Search for test files related to JSONL exporter
fd -e go -x grep -l "jsonl" {} | xargs cat
# Specifically look for test cases in the same directory

Proposed changes
This PR removes the trailing comma from the jsonl exporter (
-jsonl-exportflag) to comply with jsonlines formatting.This addresses #5860
The current implementation creates a file that is comma and newline terminated. While this works as an output file, the file does not work when ingested into other programs:
This PR removes the comma from each row in the output:
