Abstract

A system and method to facilitate backporting of bug patches to earlier versions of a project are disclosed. In one implementation, an indication that an error has been fixed for a version of a project managed by a code review system is received. An indication that a patch for the error has been applied to the earlier version of the project is received from the code review system. A message is sent to at least one participant of the project identifying the patch and the earlier version of the project, and indicating that the patch has been successfully applied to the earlier version of the project.

Claims

1. A method comprising:

receiving, by a processing device, an indication that an error has been fixed for a version of a project that is managed by a code review system;

identifying, by the processing device, a patch to fix the error;

submitting, to the code review system, a query to identify a set of participants associated with the project;

in response to a determination that backporting of the patch to an earlier version of the project does not cause a conflict;

adding, to the code review system, a datum indicating that the patch is applicable to the earlier version of the project,

receiving, from the code review system, an indication that the patch has been applied to the earlier version of the project,

generating a first message that identifies the patch, identifies the earlier version, and indicates that the patch has been successfully applied to the earlier version, and

sending the first message to at least one participant of the set of participants; and

in response to a determination that backporting of the patch to an earlier version of the project causes a conflict;

generating a second message indicating that the patch is not to be backported to the earlier version, and

sending the second message to at least one participant of the set of participants.

2. The method of claim 1 wherein the datum is a tag applied to the error.

3. The method of claim 1 wherein the datum is a tag applied to the patch.

4. The method of claim 3 wherein the patch comprises a patch file, and wherein the tag is a patch commit message embedded within the patch file.

5. The method of claim 1 wherein the set of participants comprises a maintainer of the project.

6. The method of claim 1 wherein the set of participants comprises an author of the patch.

7. The method of claim 1 wherein the set of participants comprises a person who discovered the error.

8. An apparatus comprising:

a network interface device; and

a processing device, operatively coupled to the network interface device, to;

receive an indication that an error has been fixed for a version of a project that is managed by a code review system;

identify a patch to fix the error;

in response to a determination that backporting of the patch to an earlier version of the project does not cause a conflict;

add, to the code review system, a datum indicating that the patch is applicable to the earlier version of the project,

receive, from the code review system, an indication that the patch has been applied to the earlier version of the project,

generate a first message that identifies the patch, identifies the earlier version, and indicates that the patch has been successfully applied to the earlier version, and

send, via the network interface device, the first message to at least one participant of the project.

9. The apparatus of claim 8 wherein the datum is a tag applied to the error.

10. The apparatus of claim 8 wherein the datum is a tag applied to the patch.

11. The apparatus of claim 10 wherein the patch comprises a patch file, and wherein the tag is a patch commit message embedded within the patch file.

12. The apparatus of claim 8 wherein the processing device is further to:

in response to a determination that backporting of the patch to an earlier version of the project causes a conflict;

generate a second message indicating that the patch cannot be backported to the earlier version, and

send the second message to at least one participant of the project.

13. The apparatus of claim 8 wherein the at least one participant comprises a maintainer of the project.

14. The apparatus of claim 8 wherein the at least one participant comprises a person who discovered the error.

15. A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to:

receive, by the processing device, an indication that an error has been fixed for a version of a project that is managed by a code review system;

receive, from a code review system that manages the project, a first message indicating that applying the patch to an earlier version of the project does not cause a conflict, and

send, to at least one participant of the project, a second message that identifies the patch, identifies the earlier version, and indicates that the patch has been successfully applied to the earlier version.

16. The non-transitory computer-readable storage medium of claim 15 wherein the instructions further cause the processing device to add to the code review system a datum indicating that the patch is applicable to the earlier version of the project.

17. The non-transitory computer-readable storage medium of claim 16 wherein the datum is a tag applied to the error.

18. The non-transitory computer-readable storage medium of claim 16 wherein the datum is a tag applied to the patch.

19. The non-transitory computer-readable storage medium of claim 18 wherein the patch comprises a patch file, and wherein the tag is a patch commit message embedded within the patch file.

20. The non-transitory computer-readable storage medium of claim 16 wherein the at least one participant comprises an author of the patch.
