Abstract: Embodiments profile usage of memory and other resources. Stack traces have lifespans, resource impacts, and constituent call chains. Aggregation unifies shared call chains and sums resource impacts after assigning traces to snapshot sets based on trace lifespans and user-defined snapshot request timestamps. Traces are assigned using either active aggregation or precursor aggregation. Traces spanning a snapshot request may be split. A sampled resource trace lifespan begins when the resource is sampled and ends at the next snapshot request. An allocated resource trace lifespan begins when a portion of the resource is allocated and ends when the allocated portion is freed. Resource portions not yet freed are implicitly freed when program execution ends. Call chain interval resource impact aggregation performed with multiple snapshot requests and stack trace sets creates snapshot aggregations.

The PID from the first temporary file is stored into the second, global temporary file. A singleton code block is then executed.

Abstract: The disclosed subject matter provides for software testing using metaphor based language fuzzing. Metaphor based language fuzzing can decompose a code segment into a metaphor representing the code segment. The metaphor can be mutated based on determined logical perturbations to any element of the metaphor. The mutation of the metaphor can act as a surrogate for mutation of the code segment. The mutated metaphor can be analyzed to reveal performance differences in comparison to the code segment. These performance difference can be correlated to mutation of the metaphor such that a corresponding mutation of the code segment can be correlated by extrapolation. Moreover, mutators can be stored and reused on other metaphors. Furthermore, employing a metaphor as a root language surrogate can facilitate generating a reduced number of mutators as compared to directly mutating code segments in a plurality of computer languages.

Abstract: The techniques described herein provide software testing that may concurrently process a user request using a live version of software and a shadow request, which is based on the user request, using a shadow version of software (e.g., trial or test version, etc.). The live version of software, unlike the shadow version, is user-facing and transmits data back to the users while the shadow request does not output to the users. An allocation module may vary allocation of the shadow requests to enable a ramp up of allocations (or possibly ramp down) of the shadow version of software. The allocation module may use allocation rules to dynamically initiate the shadow request based on various factors such as load balancing, user attributes, and/or other rules or logic. Thus, not all user requests may be issued as shadow requests.

A monitor software application executes on the wireless device and is configured to determine that a number of write operations issued to the non-volatile memory is greater than or equal to a write operation threshold associated with the non-volatile memory. In response, at least one application is isolated as the application responsible for issuing excessive write operations. The isolation can be carried out locally on the wireless device, or the isolation can be carried out remotely at a server by sending information about the write operations to the server. The monitor then limits additional write operations from being issued to the non-volatile memory so as to protect the non-volatile memory from becoming corrupted or inoperable.

Abstract: A fuzz testing system is described herein that represents event sources, channels, processors, and consumers as first-class entities in an application. Abstracting event-related entities allows fuzzing through injecting, dropping, reordering, and delaying events from within the application. This translates into the ability to localize the areas under test and perform fuzzing in a systematic manner. In some embodiments, the fuzz testing system tests concurrent asynchronous and event-based code, and can generate event streams based on a given statistical distribution. Representing events, event sources, processors, and sinks as first-class objects provides easy access to the event handlers and facilitates implementing fuzzing by introducing event processors between the source and the sink. Thus, the fuzz testing system improves the testability of applications and APIs with asynchronous behavior and provides a uniform framework for introducing fuzz testing into such applications.
