Log File Segmentation for Software Debugging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During software development, debugging is hindered by log files that become interspersed and shuffled due to simultaneous test executions across multiple computing systems, leading to unreliable timestamps and dispersed relevant log entries, especially when log files reach capacity and are rotated, making it difficult to identify and isolate errors.
Innovation Solution
A method that identifies the original logging position before test execution, copies relevant log entries to a separate output file after execution, and manages log file rotation to maintain proper sequencing and isolate entries for each test, ensuring that debugging can focus on specific test-related logs without interference from other tests or system issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple tests execute simultaneously across multiple computing systems, then test execution productivity increases, but log file reliability deteriorates due to interspersed and shuffled log entries
Solution Approach 1:
The patent segments the log file into multiple separate log files, with each log file dedicated to a specific test execution. This is achieved by detecting when a log file has reached capacity (rotation) and creating a new log file for the next test. The segmentation principle resolves the contradiction by maintaining reliable, test-specific log entries while allowing simultaneous test executions to proceed in parallel without interfering with each other's log integrity.
Solution Approach 2:
The patent performs preliminary actions by detecting log file rotation points and establishing clear boundaries between test log entries before tests complete. By identifying the original logging position and creating output files that capture log entries from specific test executions, the system prepares the log data in advance, ensuring reliability is maintained even as productivity increases through concurrent test execution.
2Adaptability or versatility
If log files reach capacity and are rotated, then log file management adaptability improves, but measurement precision deteriorates due to dispersed relevant log entries
Solution Approach 1:
The patent introduces an intermediary mechanism that detects log file rotation events and creates output files that consolidate log entries from specific test executions. This intermediary process bridges the gap between rotated log files and the need for precise, sequential log entry tracking. By acting as a mediator that reads from rotated log files and produces organized output files, the system maintains measurement precision while preserving the adaptability benefits of log rotation.
Solution Approach 2:
The patent creates copies of log file contents into separate output files, organized by test execution. When log files are rotated, the system copies the relevant log entries from the rotated files into dedicated output files that maintain proper sequencing. This copying mechanism preserves the adaptability of log rotation while eliminating the measurement precision problems caused by dispersed entries across multiple rotated files.
3Loss of information
If log entries from multiple tests are combined in one log file, then information completeness improves, but ease of operation deteriorates due to difficulty in isolating test-specific logs
Solution Approach 1:
The patent segments the combined log file into multiple test-specific log files or output files, where each file contains only the log entries relevant to a specific test execution. This segmentation allows developers to easily locate and analyze test-specific logs without wading through unrelated entries from other tests, significantly improving debugging ease while preserving all necessary log information across the segmented files.
Solution Approach 2:
The patent extracts test-specific log entries from the combined log file and places them into separate output files. By taking out only the relevant log entries for each test from the interspersed combined log file, the system maintains information completeness (all log entries are preserved in the appropriate output files) while dramatically improving ease of operation by allowing developers to focus on test-specific logs without distraction from other test data.

AI summary
Methods and systems for improved test execution and log file tracking are presented. In one embodiment, a method includes receiving a log file, which may be associated with a test. An original logging position of the log file may be stored and the test may be executed. Executing the test may cause logging information to be appended to the original logging position at the original logging position. An output file corresponding to the log file may be created and the original logging position within the log file may be located. A portion of the log file may then be copied to the output file starting at the original logging position.
