Distributed, non-intrusive code review in a development environment

1. A system for code review, the system comprising:

a source code editing tool configured to:

initiate a source code editing session associated with a first user;

display on a computer display, in the context of the source code editing session, a source code portion of a computer-based software application; and

accept changes to the source code portion during the source code editing session; and

a code review tool configured to:

display on the computer display, in the context of the source code editing session, a visual indicator that is associated with the source code portion, and that indicates that the source code portion was added or modified by a second user;

detect the occurrence of one or more review events associated with the source code portion; and

display a level of review that the source code portion has undergone since the addition or modification of the source code portion occurred.

2. The system of claim 1 , wherein the code review tool is configured to cease to display the visual indicator responsive to the occurrence of the review event being detected.

3. The system of claim 2 , wherein the code review tool is configured to display a different visual indicator responsive to the occurrence of the review event being detected.

4. The system of claim 2 , wherein the code review tool is configured to cease to display the visual indicator in response to the source code portion having been displayed for any of a) at least a predefined amount of time in the context of at least one source code editing session associated with the first user, b) at least a predefined number of occasions in the context of at least one source code editing session associated with the first user, and c) at least a predefined number of days in the context of at least one source code editing session associated with the first user.

5. The system of claim 3 , wherein the different visual indicator is of a lighter shade than the visual indicator.

6. The system of claim 1 , wherein the review event is the receipt of an input that is of a predefined type that represents the review event.

7. The system of claim 6 , wherein the input is one of a) an indicator indicating that the first user has reviewed the source code portion, and b) a modification made by the first user to the source code portion.

8. The system of claim 1 , wherein the code review tool is configured to display the level of review based on a predefined ranking that indicates the first user is senior to the second user.

9. The system of claim 1 , wherein the code review tool is configured to provide an indication of the review event to a source code control system.

10. A computer program product for code review, the computer program product comprising:

a computer-readable storage medium; and

computer-readable program code embodied in said computer-readable storage medium, wherein said computer-readable program code is configured to:

initiate a source code editing session associated with a first user, wherein the source code editing session is controlled by a computer-based source code editing tool that is configured to accept changes to source code of a computer-based software application during the source code editing session;

display on a computer display, in the context of the source code editing session, a source code portion of the computer-based software application; and

display on the computer display, in the context of the source code editing session, a visual indicator that is associated with the source code portion, and that indicates that the source code portion was added or modified by a second user;

detect, in the context of the source code editing session, the occurrence of one or more review events associated with the source code portion; and

display, in the context of the source code editing session, a level of review that the source code portion has undergone since the addition or modification of the source code portion occurred.

11. The computer program product of claim 10 , wherein said computer-readable program code is configured to cease to display the visual indicator responsive to the occurrence of the review event being detected.

12. The computer program product of claim 11 , wherein said computer-readable program code is configured to display a different visual indicator responsive to the occurrence of the review event being detected.

13. The computer program product of claim 11 , wherein said computer-readable program code is configured to cease to display the visual indicator in response to the source code portion having been displayed for any of a) at least a predefined amount of time in the context of at least one source code editing session associated with the first user, b) at least a predefined number of occasions in the context of at least one source code editing session associated with the first user, and c) at least a predefined number of days in the context of at least one source code editing session associated with the first user.

14. The computer program product of claim 12 , wherein the different visual indicator is of a lighter shade than the visual indicator.

15. The computer program product of claim 10 , wherein the review event is the receipt of an input that is of a predefined type that represents the review event.

16. The computer program product of claim 15 , wherein the input is one of a) an indicator indicating that the first user has reviewed the source code portion, and b) a modification made by the first user to the source code portion.

17. The computer program product of claim 10 , wherein said computer-readable program code is configured to display the level of review based on a predefined ranking that indicates the first user is senior to the second user.

18. The computer program product of claim 10 , wherein said computer-readable program code is configured to provide an indication of the review event.
