Selective Software Package Rollback Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing software package rollback solutions do not allow for easy restoration of specific packages along with their dependencies, leading to unnecessary removal of functional packages during system rollback.
Innovation Solution
Implementing a package-based mechanism to roll back individually specified software packages and their dependencies to a specific point in time, using transaction data recorded in a database, allowing for selective restoration of only affected packages while leaving others intact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing rollback solutions are used to restore the system to a previous state, then the system can be returned to a prior working state, but all packages installed since that time are removed including those that function properly
Solution Approach 1:
The patent segments the rollback operation by allowing selective identification of specific packages to be rolled back, rather than rolling back all packages installed since a checkpoint. The system divides the package set into two groups: packages to be rolled back and packages to remain installed, enabling targeted restoration without unnecessary removal of functional packages.
Solution Approach 2:
The patent applies local quality by treating different packages differently during the rollback process. Each package can have its own rollback status determined by user specification or automated conflict detection, allowing the system to apply restoration selectively only where needed rather than uniformly across all packages.
2Object-generated harmful factors
If existing rollback solutions are used to remove the offending package, then the conflicting package can be removed, but additional functional packages are also removed requiring re-installation
Solution Approach 1:
The patent extracts only the problematic package(s) from the set of packages installed since the checkpoint, identifying and removing only those specific packages that cause conflicts while leaving other packages intact. This extraction approach prevents the collateral removal of functional packages that would otherwise require time-consuming re-installation.
3Stability of the object's composition
If all packages installed since a checkpoint are rolled back, then the system returns to a known good state, but functional packages are unnecessarily removed
Solution Approach 1:
The patent introduces dynamic package management where the rollback set is not fixed but can be adjusted based on user input and conflict analysis. The system dynamically determines which packages should be rolled back by analyzing actual conflicts and allowing user specification, making the process adaptable rather than rigid.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system analyzes package conflicts and provides information to the user about which packages are causing problems. This feedback loop allows the user to make informed decisions about which packages to rollback, combining automated conflict detection with user control.

AI summary
Apparatus, systems, and methods may operate to receive a request to roll back one or more individually specified software packages to their respective package states at a prior time on a processing system, to determine a series of transactions on the processing system associated with the individually specified software packages and their dependencies, conducted between the current time and the prior time, and to roll back the dependencies and the individually specified software packages to the respective package states on the processing system. Additional apparatus, systems, and methods are disclosed.
