Abstract
A system for managing the memory of a software component, such as a software library, such that the state of the software component is preserved after an update to the software component. There are two special types of memory allocated within the software component: transient memory and enduring memory. Memory needed to be preserved between two calls of the library is allocated as enduring memory. Transient memory persists until it is freed or when the software component is deleted, whichever comes first. Upon updating to a new version of a software component, the transient memory is released, while the enduring memory is preserved for use by the new version.
