Various embodiments of the present invention provide a method, system, and program product that perform the following operations: organizing a project having source code into a stacked-layer framework, the stacked-layer framework having: (i) a code layer including the source code of the project, (ii) a label layer including one or more label pages labelling the source code according to respective features of the source code, and (iii) a mask layer including one or more mask pages concealing portions of the source code according to labels of the label layer; receiving a request from a user to utilize a portion of the project, wherein the request includes a user requirement identifying one or more desired features; identifying a mask page of the one or more mask pages corresponding to the one or more desired features identified by the user requirement; and communicating the identified mask page to the user.

Delivering portions of source code based on a stacked-layer framework

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.

Container image management

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.

Multi-version compatibility for connectivity protocols

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.

Intelligent layer control of redundant content in container images

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.

Facilitating use of an unfamiliar command line tool via a familiar command line tool

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.
