Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Software builds are inefficient due to the execution of duplicate software build actions and the need to retrieve build dependencies, which can take several hours and consume significant computational resources.

Innovation Solution

Implementing a system that merges duplicate software build actions and utilizes a snapshot storage volume to cache build dependencies, reducing redundant computations and leveraging tree caching to optimize build processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If software build actions are executed without merging duplicates, then build completeness is maintained, but build time increases significantly due to redundant computations

Engineering Contradiction:

Improvebuild speedVSAvoidredundant computation time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent merges duplicate software build actions by comparing hash values of build specifications. When identical build actions are detected (same hash value), the system consolidates them into a single execution, eliminating redundant computations and significantly reducing build time while maintaining build completeness

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If build dependencies are retrieved from external sources during each build, then build freshness is ensured, but computational resources and time are consumed

Engineering Contradiction:

Improvebuild dependency freshnessVSAvoidcomputational resource consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent pre-loads build dependencies into a local cache before the actual build process. By preparing dependencies in advance and storing them locally, the system ensures build freshness while significantly reducing computational resource consumption during the build execution, as dependencies are retrieved from local cache rather than external sources

Inventive Principle:

Principle #10Preliminary action

3Manufacturing precision

If the entire source code tree is processed in each build, then build accuracy is maintained, but build time increases due to unnecessary processing of unchanged files

Engineering Contradiction:

Improvebuild accuracyVSAvoidprocessing time of unchanged files

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent implements tree caching that tracks hash values of individual files and directories in the source code tree. During builds, the system processes only those portions of the tree that have changed (detected by hash value comparison), while skipping unchanged portions. This maintains build accuracy by ensuring all necessary changes are processed while eliminating wasted time on unchanged files

Inventive Principle:

Principle #3Local quality

AI summary

A cached parent node of a remotebuild tree cache may be identified in a cache associated with a parent node of a file system. The cache may be configured to store a plurality of cached traversal results, and each may be associated with a corresponding node of the file system. The parent node may be associated with a project root of the file system. A current hash value of the parent node may be compared with a cached hash value of the cached parent node. In response to determining that the cache is stale based on the current hash value and the cached hash value not matching, the cache may be updated by traversing a set of descendent nodes of the parent node based upon the cache miss and updating the cached parent node with a traversal result and with the current hash value of the parent node.
