Abstract

A system for a distributed repository includes an input interface and a processor. The input interface is to receive a request to change a portion of code. The processor is to determine a change reference and an existing reference, indicate to lock one or more repositories, determine whether swapping references is approved by a vote, and in the event that swapping references is approved by a vote, swap the references and indicate to unlock the one or more repositories.

Claims

1. A system for a distributed repository, comprising:

an input interface to receive a request to change a portion of code; and

a processor to;

determine a change reference and an existing reference;

indicate to lock one or more repositories;

determine whether swapping references is approved by a vote;

in the event that swapping references is approved by a vote;

swap the references; and

to indicate to unlock the one or more repositories.

2. The system of claim 1, wherein swapping references comprises replacing the existing reference with the change reference.

3. The system of claim 1, wherein a reference comprises a pointer.

4. The system of claim 1, wherein the request to change the portion of code comprises a new portion of code.

5. The system of claim 4, wherein the new portion of code comprises a code block and associated metadata.

6. The system of claim 4, wherein the processor is additionally to store the new portion of code.

7. The system of claim 4, wherein the processor is additionally to provide the new portion of code to other systems.

8. The system of claim 4, wherein the processor is additionally to determine whether the new portion of code is valid.

9. The system of claim 1, wherein the processor provides an indication of a ready to lock state.

10. The system of claim 1, wherein indicating to lock one or more repositories comprises indicating to lock a repository stored on the system.

11. The system of claim 1, wherein indicating to lock one or more repositories comprises indicating to lock a repository stored on an other system.

12. The system of claim 1, wherein determining whether swapping references is approved by a vote comprises receiving a swap indication from one or more other systems.

13. The system of claim 1, wherein determining whether swapping references is approved by a vote comprises determining whether a majority of swap indications indicate to swap.

14. The system of claim 1, wherein the processor is further to:

in the event a swap indication to not swap is received but swapping references is approved, provide a repair indication to the system that provided the swap indication to not to swap.

15. The system of claim 1, wherein the processor is further to:

in the event swapping references is not approved, provide an indication that changing a portion of code has failed.

16. The system of claim 1, wherein the processor is further to:

in the event swapping references is approved, provide an indication that changing a portion of code has completed.

17. The system of claim 1, wherein the system and one or more other systems each determine whether swapping references is approved by a vote.

18. The system of claim 1, wherein the processor is further to:

in the event swapping references is approved, provide an indication to one or more other systems to swap references.

19. A method for a distributed repository, comprising:

receiving a request to change a portion of code;

determining, using a processor, a change reference and an existing reference;

indicating to lock one or more repositories;

determining whether swapping references is approved by a vote; and

in the event that swapping references is approved by a vote;

swapping the references; and

indicating to unlock the one or more repositories.

20. A computer program product for a distributed repository, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

receiving a request to change a portion of code;

determining, using a processor, a change reference and an existing reference;

indicating to lock one or more repositories;

determining whether swapping references is approved by a vote; and

in the event that swapping references is approved by a vote;

swapping the references; and

indicating to unlock the one or more repositories.
