Abstract: Dynamically revising an in-process build is disclosed. A build system receives a build configuration comprising information that defines a plurality of successive stages. Each stage includes at least one step, and one or more of the stages include a plurality of successive steps. The build configuration defines a build process that, when completed, alters a state of a storage device. The build system initiates a build process sequence on the build configuration. The build system, after initiating the build process sequence, receives notification of a desire to add a revision to a particular stage of the plurality of stages defined in the build configuration. A determination is made that performance of the particular stage has or has not begun. In response to the determination, a subsequent build process action is performed.

Abstract: A processing device of a system may determine that a new service virtual machine (VM) image is available, the new service VM image comprising an update for a current service VM image. The system may identify a first instance of a first service VM that is presently running, wherein the first instance of the first service VM was created from the current service VM image and has a floating internet protocol (IP) address. The system may further create a second instance of the first service VM using the new service VM image, transfer active sessions of the first instance of the first service VM to the second instance of the first service VM, and reassign the floating IP address from the first instance of the first service VM to the second instance of the first service VM.

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.
