Patent number: 11960870Abstract: Methods, systems, and computer program products for container image management are disclosed. In a method, a first group of operations that are performed in respective layers in a base image are obtained. A second group of operations that are performed in respective layers not comprised in the base image are obtained. The second group of operations are optimized based on a comparison between the first and second groups of operations. A destination container image is generated based on the optimized second group of operations and the base image.Type: GrantFiled: February 23, 2022Date of Patent: April 16, 2024Assignee: International Business Machines CorporationInventors: Lu Yan Li, Zhan Peng Huo, Fei Tan, Jiu Chang Du

Patent number: 11811599Abstract: A connection request from one computing entity is obtained. The connection request is a request to connect to another computing entity and includes a requested connectivity protocol configuration. A determination is made as to whether the requested connectivity protocol configuration is a match to a particular connectivity protocol configuration of the other computing entity. Based on determining that the requested connectivity protocol configuration is not a match to the particular connectivity protocol configuration of the other computing entity, a selected configuration file that is a match to the requested connectivity protocol configuration is selected from a plurality of configuration files. Based on selecting the selected configuration file, routing of the connection request to a connectivity protocol service corresponding to the selected configuration file is initiated to facilitate establishing a connection between the one computing entity and the other computing entity.Type: GrantFiled: January 23, 2023Date of Patent: November 7, 2023Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Jiu Chang Du, Kui Zhang, Zhan Peng Huo, Yong Qing Xu, Peng Hui Jiang

Patent number: 11803303Abstract: Intelligent layer control for building image files into new container images while avoiding redundant files stored between read-write and read-only image layers. Pre-commit processing module (PPM) filters updated files. Hash values of updated files are compared with hash values of original files. Where hash values are the same, PPM generates an OMD file that updates the inode metadata of original files with metadata of the updated file and removes the updated file. Hash values that are not the same, with differ values less than a threshold value, PPM generates an OMD file with updates to the inode metadata, content change flag and/or delta content info reflecting the updated file and removes updated file from container file system. OMD files are passed to storage driver whereby metadata and/or changes to content are overridden and merged with original file content generating a single unified user view of the container file system.Type: GrantFiled: April 8, 2022Date of Patent: October 31, 2023Assignee: International Business Machines CorporationInventors: Zhan Peng Huo, Fei Tan, Lu Yan Li, Jiu Chang Du

Patent number: 11200078Abstract: A method of translating a first command to a target command includes receiving the first command in a first command format, acquiring a first utility intermediate representation framework (UIRF) including a plurality of a first set of node instances. The method also includes acquiring a first user utility intermediate representation framework (UUIRF) by parsing the first command into one or more command elements, representing each command element by a respective node instance of the first UIRF, the first UUIRF representing an intention of the first command, acquiring a target UUIRF based on a target format, the target UUIRF including a target set of node instances, entering information from each of the first set of node instances of the first UUIRF into a corresponding node instance of the target set of node instances in the target UUIRF, and constructing the target command based on the target UUIRF.Type: GrantFiled: November 6, 2020Date of Patent: December 14, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Fei Tan, Jiu Chang Du, Zhan Peng Huo, Lu Yan Li

Patent number: 8997059Abstract: A method and reverse debugger are provided for reversely debugging a program. The method includes: obtaining debugging information of the program as outputted by a compiler, the debugging information including information related to extended basic blocks of the program; in response to the program entering into reverse debugging, setting a reverse debugging checkpoint at an entry address of at least one extended basic block; in response to the program reaching a set reverse debugging checkpoint, storing information required by debugging that corresponds to the reverse debugging checkpoint; in response to receiving a set reverse debugging target breakpoint, making the program return to a reverse debugging checkpoint located before the reverse debugging target breakpoint and nearest to the reverse debugging target breakpoint, obtaining information required to be stored by the debugging stored at the reverse debugging checkpoint, and continuing to execute the program till the reverse debugging target breakpoint.Type: GrantFiled: July 29, 2013Date of Patent: March 31, 2015Assignee: International Business Machines CorporationInventors: Fan Wang, Qi Li, Jiu Chang Du, Xiao Ling Chen, Li Gang Mei
