Abstract

Access to a source code file stored at a server is provided to a plurality of user devices, via a network. The source code file may comprise software code. The source code file stored at the server is updated based on a plurality of changes received from respective user devices, substantially in real-time. A selection of an option to execute the source code file is received from one of the plurality of user devices. In response to the selection, the source code file is executed, substantially in real-time.

First claim

The invention claimed is:

1. A method of providing software development services, the method comprising:
providing, by one or more processors, to a plurality of user devices, access to a source code file via a network;
receiving, by the one or more processors, a first change to the source code file and a second change to the source code file;
detecting, by the one or more processors, a conflict between the first and second change to the source code file;
determining, in response to the detection of the conflict, by the one or more processors, a first transformed operation based on the first change to the source code file and a second transformed operation based on the second change to the source code file;
modifying, by the one or more processors, the source code by applying the first transformed operation and the second transformed operation to the source code;
determining, for each of the plurality of user devices, by the one or more processors, a local portion of the source code file stored by each respective user device, the local portion being less than all of the source code file and each respective user device storing only a local portion of the source code file;
determining, by the one or more processors, whether a modified portion of the source code corresponds to any of the local portion of the source code file stored by the plurality of user devices; and
transmitting; by the one or more processors, the modified portion of the source code to a respective user device when the modified portion of the source code corresponds to the local portion of the source code file stored by the respective user device.

2. The method of claim 1 , wherein the conflict is detected by determining that updating the source code in accordance with the first change produces an updated source code inconsistent with the second change.

3. The method of claim 1 , wherein applying the first change to the source code file followed by applying the second change to the source code file produces a different result than applying the second change to the source code file followed by applying the first change to the source code file.

4. The method of claim 1 , wherein determining the first transformed operation and the second transformed operation comprises determining that an application of the first transformed operation to the source code followed by an application of the second transformed operation to the source code is equivalent to the application of the second transformed operation to the source code followed by the application of the first transformed operation to the source code.

5. The method of claim 1 , wherein the first change is received from a first user and the second change is received from a second user, and the first change and the second change are received substantially simultaneously.

6. The method of claim 1 , wherein the source code file comprises software code, the method further comprising:
allowing a plurality of users employing the plurality of user devices to collaboratively edit the software code.

7. The method of claim 6 , wherein the plurality of users have substantially simultaneous access to the source code file stored at a server, via the network.

8. The method of claim 1 , wherein modifying the source code comprises modifying only a portion of the source code.

9. A non-transitory computer-readable medium having stored thereon instructions which, when executed by one or more processors, cause the one or more processors to perform a method of providing software development services, the method comprising:
providing to a plurality of user devices, access to a source code file via a network;
receiving a first change to the source code file and a second change to the source code file;
detecting a conflict between the first and second change to the source code file;
determining, in response to the detection of the conflict, a first transformed operation based on the first change to the source code file and a second transformed operation based on the second change to the source code file;
modifying the source code by applying the first transformed operation and the second transformed operation to the source code;
determining, for each of the plurality of user devices, a local portion of the source code file stored by each respective user device, the local portion being less than all of the source code file and each respective user device storing only a local portion of the source code file;
determining whether a modified portion of the source code corresponds to any of the local portion of the source code file stored by the plurality of user devices; and
transmitting the modified portion of the source code to a respective user device when the modified portion of the source code corresponds to the local portion of the source code file stored by the respective user device.

10. The non-transitory computer-readable medium of claim 9 , wherein the conflict is detected by determining that updating the source code in accordance with the first change produces an updated source code inconsistent with the second change.

11. The non-transitory computer-readable medium of claim 9 , wherein applying the first change to the source code file followed by applying the second change to the source code file produces a different result than applying the second change to the source code file followed by applying the first change to the source code file.

12. The non-transitory computer-readable medium of claim 9 , wherein determining first transformed operation and the second transformed operation comprises determining that the an application of the first transformed operation to the source code followed by the an application of the second transformed operation to the source code is equivalent to the application of the second transformed operation to the source code followed by the application of the first transformed operation to the source code.

13. The non-transitory computer-readable medium of claim 9 , wherein the first change is received from a first user and the second change is received from a second user, and the first change and the second change are received substantially simultaneously.

14. The non-transitory computer-readable medium of claim 9 , wherein the source code file comprises software code, the method further comprising:
allowing a plurality of users employing the plurality of user devices to collaboratively edit the software code.

15. The non-transitory computer-readable medium of claim 14 , wherein the plurality of users have substantially simultaneous access to the source code file stored at a server, via the network.

16. The non-transitory computer-readable medium of claim 9 , wherein modifying the source code comprises modifying only a portion of the source code.

17. A system for providing software development services, the system comprising:
one or more computing devices having one or more processors coupled to memory, the one or more processors being configured to:
provide to a plurality of user devices, access to a source code file via a network;
receive a first change to the source code file and a second change to the source code file;
detect a conflict between the first and second change to the source code file;
determine, in response to the detection of the conflict, a first transformed operation based on the first change to the source code file and a second transformed operation based on the second change to the source code file;
modify the source code by applying the first transformed operation and the second transformed operation to the sou
