Abstract

Concepts for managing code copied from a source repository to a target repository are proposed. Example embodiments comprises generating metadata relating to code copied from the source repository. At the target repository, source repository is monitored to determine if the code copied from the source repository has been modified within the source repository based on the metadata. Responsive to determining the code copied from the source repository has been modified within the source repository, a notification relating to the modification is generated at the target repository.

Claims

1. A computer-implemented method comprising:

creating a second instance of code in a target repository by copying a first instance of code in a source repository to the target repository;

generating, by a processor, metadata relating to the first instance of code;

at the target repository, monitoring the source repository to determine if the first instance of code has been modified based on the metadata;

responsive to determining the first instance of code has been modified, generating, at the target repository, a notification relating to the modification; and

disabling the monitoring when the first instance of code and the second instance of code have diverged beyond a predetermined threshold value.

2. The method of claim 1, further comprising, responsive to a disable command, terminating monitoring of the source repository.

4. The method of claim 2, further comprising

generating the disable command based on a user input signal.

5. The method of claim 1, further comprising

responsive to the notification relating to the modification, modifying the second instance of code at the target repository based on the modification.

6. The method of claim 1, further comprising responsive to the notification relating to the modification, providing a component for updating code at the target repository based on the modification.

7. The method of claim 1, wherein the metadata relating to the first instance of code comprises information relating to at least one of:

the source repository,

a source file comprising the first instance of code,

a source code entity comprising the first instance of code,

a location of the first instance of code in the source repository,

a description of the first instance of code,

a function/method,

change history,

programming language, and

a property of the first instance of code.

8. The method of claim 1, wherein the first instance of code comprises source code for a micro-service.

3. (canceled)

9. A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by at least one processor to cause the at least one processor to perform a method comprising:

creating a second instance of code in a target repository by copying a first instance of code in a source repository to the target repository;

generating, by a processor, metadata relating to the first instance of code;

at the target repository, monitoring the source repository to determine if the first instance of code has been modified based on the metadata;

responsive to determining the first instance of code has been modified, generating, at the target repository, a notification relating to the modification; and

disabling the monitoring when the first instance of code and the second instance of code have diverged beyond a predetermined threshold value.

10. The computer program product of claim 9, wherein the at least one processor is adapted to execute computer program code of said computer program product.

11. The computer program product of claim 10, wherein the at least one processor is adapted to implement a part of a micro-service-oriented architecture.

12. A system comprising:

a copy component adapted to create a second instance of code in a target repository by copying a first instance of code in a source repository to the target repository;

a metadata component adapted to generate metadata relating to the first instance of code;

at the target repository, a monitor component adapted to monitor the source repository to determine if the first instance of code has been modified based on the metadata;

a notification component adapted to generate, at the target repository in response to the determining, a notification relating to the modification; and

a disabling component configured to disable the monitoring when the code in the source repository and the code within the target repository have diverged beyond a predetermined threshold value.

13. The system of claim 12, wherein responsive to a disable command, the monitor component is adapted to terminate monitoring of the source repository.

15. The system of claim 13, wherein the system is adapted to generate the disable command based on a user input signal.

16. The system of claim 12, further comprising a code modifier adapted, in response to the notification relating to the modification, to modify the second instance of code at the target repository based on the modification.

17. The system of claim 12, further comprising a development component adapted, in response to the notification relating to the modification, to provide a component for updating code at the target repository based on the modification.

18. The system of claim 12, wherein the metadata relating to the first instance of code comprises information relating to at least one of:

the source repository,

a source file comprising the first instance of code,

a source code entity comprising the first instance of code,

a location of the first instance of code in the source repository,

a description of the first instance of code,

a function/method,

change history,

programming language, and

a property of the first instance of code.

19. The system of claim 12, wherein the first instance of code comprises source code for a micro-service.

20. The system of claim 19, wherein at least one processor is adapted to implement a part of a micro-service-oriented architecture.
