Abstract

Approaches to memory management and synchronization are described relating to provision of highly robust and highly available servers that can serve multiple requests in parallel. Programming objects can be analyzed at design time by comparison to predefined patterns to identify a set of requirements and rules that must be followed to ensure that all part of a program cooperate. In highly complex programming environments, enforcement of such rules for a program as a whole can be quite difficult. As such, analysis of compliance can desirably occur at a programming object level.

Claims19

Dependent claims

A computer program product comprising a machine-readable medium storing instructions that, when executed by a system comprising at least one programmable processor, cause the system to perform operations comprising:

detecting, at design time, a programming object, the programming object comprising part of a server application that includes a plurality of other programming objects;
identifying one or more memory management and synchronization characteristics of the programming object and extracting one or more memory management and synchronization constraints defined at design time for the programming object;
matching the programming object to a matching memory management and synchronization pattern, the matching comprising comparing the one or more identified memory management and synchronization characteristics to a set of predefined memory management and synchronization patterns;
reviewing the extracted one or more memory management and synchronization constraints against a predefined set of constraints associated with the matching memory management and synchronization pattern;
and
returning an error message if the one or more memory management and synchronization constraints defined for the programming object do not comprise the predefined set of constraints.
