Abstract

The present invention generally provides methods, systems, and articles of manufacture that provide a managed software development environment. In one embodiment, software programmers interact with the managed software development environment to develop a target software application. Embodiments of the invention prevent source code from being included in the target software application if the license for the project is incompatible with either the license under which the source code is available or with company policy. Embodiments of the invention further prevent linking to a library file if the library file is available under a license that is incompatible with the intended license of the target software application.

Claims

1. A computer-implemented method for a source code editing tool to manage a software development project that incorporates code objects subject to licensing restrictions, comprising:

selecting a code object to paste into a first source code file, the first source code file being associated the software development project, wherein the code object includes one or more lines of source code copied from a second source code file, the second source code file not being associated with the software development project;

identifying a target software license associated with the software development project;

identifying a license associated with the code object;

upon determining that the license associated with the code object is compatible with the target software license pasting the one or more lines of source code from the second source code file into the first source code file;

upon determining that the license associated with the code object is incompatible with the target software license, prompting a user interacting with the source code editing tool that the one or more lines of source code have not been pasted into the first source code file;

providing the user with an interface to override the determining that the license associated with is incompatible with the target software license; and

in response to receiving a request received, via the interface, to override the determination that the license associated with the code object is incompatible with the target software license, pasting the one or more lines of source code from the second source code file into the first source code file.

2. The method of claim 1, further comprising, updating the target software license associated with the software development project based on a requirement of the license under which the one or more lines of source code are distributed.

3. The method of claim 2, wherein the requirement is one of an attribution requirement and a distribution requirement restricting how a software application corresponding to the software development project may be distributed.

4. The method of claim 1, wherein the one or more lines of source code identify a library linked to the first source code file, when compiled and executed.

5. The method of claim 1, wherein the license associated with the code object comprises an open source license.

6. The method of claim 1, wherein the code object is associated with the software development project as a read only code object, thereby prohibiting a user from modifying a version of the code object included in the software development project.

7. A computer-readable storage medium containing a program which, when executed on a processor, performs an operation for a source code editing tool to manage a software development project that incorporates code objects subject to licensing restrictions, the operation comprising:

selecting a code object to paste into a first source code file, the first source code file being associated the software development project, wherein the code object includes one or more lines of source code copied from a second source code file, the second source code file not being associated with the software development project;

identifying a target software license associated with the software development project;

identifying a license associated with the code object;

upon determining that the license associated with the code object is compatible with the target software license pasting the one or more lines of source code from the second source code file into the first source code file;

upon determining that the license associated with the code object is incompatible with the target software license, prompting a user interacting with the source code editing tool that the one or more lines of source code have not been pasted into the first source code file;

providing the user with an interface to override the determining that the license associated with is incompatible with the target software license; and

in response to receiving a request received, via the interface, to override the determination that the license associated with the code object is incompatible with the target software license, pasting the one or more lines of source code from the second source code file into the first source code file.

8. The computer-readable storage medium of claim 7, wherein the operation further comprises, updating the target software license associated with the software development project based on a requirement of the license under which the one or more lines of source code are distributed.

9. The computer-readable storage medium of claim 8, wherein the requirement is one of an attribution requirement and a distribution requirement restricting how a software application corresponding to the software development project may be distributed.

10. The computer-readable storage medium of claim 7, wherein the one or more lines of source code identify a library linked to the first source code file, when compiled and executed.

11. The computer-readable storage medium of claim 7, wherein the license associated with the code object comprises an open source license.

12. The computer-readable storage medium of claim 7, wherein the code object is associated with the software development project as a read only code object, thereby prohibiting a user from modifying a version of the code object included in the software development project.

13. A system, comprising:

a processor; and

a memory containing a source-to-source compiler application, which when executed by the processor is configured to generate source code for a target architecture by performing the steps of;

selecting a code object to paste into a first source code file, the first source code file being associated the software development project, wherein the code object includes one or more lines of source code copied from a second source code file, the second source code file not being associated with the software development project,

identifying a target software license associated with the software development project,

identifying a license associated with the code object,

upon determining that the license associated with the code object is compatible with the target software license pasting the one or more lines of source code from the second source code file into the first source code file,

upon determining that the license associated with the code object is incompatible with the target software license, prompting a user interacting with the source code editing tool that the one or more lines of source code have not been pasted into the first source code file,

providing the user with an interface to override the determining that the license associated with is incompatible with the target software license, and

in response to receiving a request received, via the interface, to override the determination that the license associated with the code object is incompatible with the target software license, pasting the one or more lines of source code from the second source code file into the first source code file.

14. The system of claim 13, wherein the steps further comprise, updating the target software license associated with the software development project based on a requirement of the license under which the one or more lines of source code are distributed.

15. The system of claim 14, wherein the requirement is one of an attribution requirement and a distribution requirement restricting how a software application corresponding to the software development project may be distributed.

16. The system of claim 13, wherein the one or more lines of source code identify a library linked to the first source code file, when compiled and executed.

17. The system of claim 13, wherein the license associated with the code object comprises an open source license.

18. The system of claim 13, wherein the code object is associated with the software development project as a read only code object, thereby prohibiting a user from modifying a version of the code object included in the software development project.
