Abstract

Methods and systems for facilitating incremental software deployment are disclosed. For example, a method can include receiving a command to deploy a second version of software to a computing system for execution on the computing system. In response to the command, differences between the second version of the software and a first version of the software being executed on the computing system are determined. Code changes to be made to the first version of the software to produce the second version of the software are determined based on the differences. The code changes to be made to the first version of the software are transmitted to the computing system.

Claims

1. A method, comprising:

receiving a command to deploy a second version of software to a computing system for execution on the computing system;

in response to receiving the command, determining, using at least one processor, differences between the second version of the software and a first version of the software being executed on the computing system;

determining, using the at least one processor, code changes to be made to the first version of the software to produce the second version of the software based on the differences;

transmitting to the computing system the code changes to be made to the first version of the software;

after transmitting to the computing system the code changes, receiving a notification from the computing system whether the code changes were implemented on the computing system without a restarting of the software executing on the computing system.

2. The method of claim 1, the command being initiated in response to user input.

3. The method of claim 1, the command being initiated in response to the second version of the software becoming available.

4. The method of claim 1, the code changes comprising at least one binary library.

5. The method of claim 1, the code changes comprising at least one class file.

6. The method of claim 1, further comprising:

if the notification does riot indicate that the code changes were implemented on the computing system without a restarting of the software executing on the computing system, transmitting an instruction to restart the software executing on the computing system to implement any of the code changes not previously implemented on the computing system.

7. The method of claim 6, further comprising:

transmitting to a second computing system the code changes to be made to the first version of the software executing in the second computing system;

after transmitting to the second computing system the code changes, receiving a notification from the second computing system whether the code changes were implemented on the second computing system without a restarting of the software executing on the second computing system; and

if the notification does not indicate that the code changes were implemented on the second computing system without a restarting of the software executing on the second computing system, determining a relative order in which the second version of the software is to be implemented on the first computing system and the second computing system, and transmitting a second instruction to restart the software executing on the second computing system to implement any of the code changes not previously implemented on the second computing system according to the relative order.

8. The method of claim 6, further comprising:

if the notification indicates that the code changes were implemented on the computing system without a restarting of the software executing on the computing system, waiting a predefined period of time; and

after waiting the predefined period of time, transmitting to a second computing system the code changes to be made to the first version of the software executing in the second computing system.

9. The method of claim 1, the code changes comprising binary libraries of the second version of the software, the binary libraries comprising all binary libraries of the second version of the software that are different from corresponding libraries of the first version of the software.

10. A non-transitory computer-readable medium having encoded thereon instructions which, when executed on at least one processor, cause the at least one processor to perform operations, the operations comprising:

executing a first version of software;

receiving, at a computing system from a deployment system configured to determine differences between a second version of the software and the first version of the software and determine code changes to be made to the first version of the software to produce the second version of the software, the code changes to be implemented in a first version of software executing on the computing system;

analyzing the code changes to determine if all of the code changes are implementable while the computing system is executing the first version of the software;

if all of the code changes are implementable while the computing system is executing the first version of the software, implementing all of the code changes while the software is executing on the computing system to produce a second version of the software; and

if less than all of the code changes are implementable while the computing system is executing the first version of the software, transmitting an indication that less than all of the code changes are implementable while the computing system is executing the first version of the software.

11. The non-transitory computer-readable medium of claim 10, the operations further comprising:

after transmitting the indication, receiving an instruction at the computing system to restart the software to implement the code changes to the first version of the software; and

in response to receiving the instruction, stopping execution of the first version of the software in the computing system, implementing all of the code changes to the first version of the software to produce the second version of the software, and restarting the software after implementing all of the code changes.

12. The non-transitory computer-readable medium of claim 11, the operations further comprising:

after restarting the software, transmitting a second indication that the second version of the software, including the code changes, is executing on the computing system.

13. The non-transitory computer-readable medium of claim 10, the analyzing of the code changes comprising:

identifying a programming language associated with each of the code changes; and

determining if each of the code changes is implementable while the computing system is executing the first version of the software based on the programming language identified with each of the code changes.

14. The non-transitory computer-readable medium of claim 10, the implementing of all of the code changes comprising:

storing each of the code changes in the computing system; and

modifying each reference involving code of the first version of the software executing on the computing that is to be replaced by one of the code changes to refer to a corresponding stored code change.

15. The non-transitory computer-readable medium of claim 14, the modifying of each reference involving code of the software executing on the computing system comprising:

for each reference, determining if the code associated with the reference is currently being executed, modifying the reference to direct execution to the corresponding stored code change if the code associated with the reference is not currently being executed, and awaiting for execution of the code associated with the reference to complete before modifying the reference if the code associated with the reference is currently being executed.

16. A system comprising:

a computing system comprising at least one processor to;

execute a first version of software;

receive, from a deployment system configured to receive a command to deploy a second version of the software to the computing system for execution on the computing system and determine code changes to be made to the first version of the software to produce a second version of the software based on the differences, the code changes to be made to the first version of the software;

receive the code changes to be made to the first version of software executing on the computing system;

analyze the code changes to determine if all of the code changes are implementable while the computing system is executing the first version of the software;

implement all of the code changes while executing the software to produce the second version of the software if all of the code changes are implementable while the computing system is executing the first version of the software; and

transmit a notification to the deployment system if less than all of the code changes are implementable while the computing system is executing the first version of the software.

17. The system of claim 16, the deployment system to:

receive the notification from the computing system; and

transmit a command to the computing system to restart the software executing on the computing system to implement all of the code changes not previously implemented on the computing system in response to receiving the notification.

18. The system of claim 17, the computing system to:

receive the command from the deployment system to restart the software executing on the computing system;

stop execution of the first version of the software in the computing system in response to receiving the command;

implement all of the code changes to the first version of the software to produce the second version of the software; and

restart the software after implementing all of the code changes.

19. The system of claim 18, the computing system to:

transmit a second notification to the deployment system to indicate that the second version of the software, including the code changes, is executing on the computing system in response to restarting the software.
