Abstract: Presenting historical state associated with prior execution of an entity. Based on replaying segment(s) of execution of an entity based on a trace, embodiments could present an indication of whether a value of a code element is, at a first execution time point, unknown, known, previously known, and/or known in the future. Additionally, or alternatively, embodiments could present an indication of a value relied upon by simulated execution of a function at a second execution time point, along with an indication of a timing of knowledge of the value in relation to the second execution time point. Additionally, or alternatively, embodiments could present an indication that a return value of a function would be known if the function had executed at a third execution time point, or an indication that the return value would be unknown if the function had executed at the third execution time point.

Abstract: An online system ranks test cases run in connection with check-in of sets of software files in a software repository. The online system ranks the test cases higher if they are more likely to fail as a result of defects in the set of files being checked in. Accordingly, the online system informs software developers of potential defects in the files being checked in early without having to run the complete suite of test cases. The online system determines a vector representation of the files and test cases based on a neural network. The online system determines an aggregate vector representation of the set of files. The online system determines a measure of similarity between the test cases and the aggregate vector representation of the set of files. The online system ranks the test cases based on the measures of similarity of the test cases.

Abstract: Techniques for generating serialized view models that are used for both debugging an application and application support. The techniques include executing an application, creating a view model associated with the application, the view model including information associated with a service provided by the application, and presenting a user interface associated with the view model. The techniques can further include identifying, while presenting the user interface, an error occurring with the application, capturing a stack trace corresponding to the error, capturing a process image of the view model, serializing the process image of the view model to generate a serialized view model, and sending the stack trace and the serialized view model to a service. The service can then use the stack trace and the serialized view model to debug the application.

Abstract: Provided is a compile time interface to run-time libraries that can reduce processing overhead in loops. A compile time interface identifies, at compile time, a loop that contains a library function in response to detecting a compiler hint associated with the library function. The compile time interface generates a bypass structure and modifies the loop to include a call to a planning function for a first pass through the loop and a call to a bypass function for one or more subsequent passes though the loop. The planning function sets the bypass function equal to an optimized library if one or more selected arguments to the library function are loop-invariant.

Abstract: Dynamically scheduled testing of a software application on one or more devices are disclosed. The system can schedule and execute of one or more test cases associated with a software application. When a device becomes available for testing, the system can determine the list of commits that have not yet been tested. If there are outstanding untested commits, the system can determine the list of test cases in a test plan that are to be scheduled and executed. For each test in the list of test cases, the system can compute an urgency value. Urgency value can be a function of the untested commits. For example, urgency value can be the number of untested commits associated with each test case. The system can then sort the test cases based on the urgency value and schedule the most “urgent” test case for execution.

Abstract: A system and methods for automatically localizing faults for functional field failures that enables users to enter symptoms of a failure that occur during deployment of a given application along with the values of the input and configuration parameters in order to return locations in the source code that are likely to contain specific faults as well as show navigation paths from a suggested to the failure such that the code may be corrected. Successful and faulty runs of a software application are executed, and used to obtain ground facts and a knowledge base. A particular formula for the ground facts and knowledge base is discussed. A Markov Logic Network (MLN) is generated from the ground facts and knowledge base. Abductive reasoning based on the MLN is used to localize faults for the user-entered functional field failures.

Abstract: Management of an extensive code database having multiple user tenants building code is provided. A request to check-in code is received, and a build and validation to check-in the update to a user's code is performed. The validation results in indication of an error due to a bad state of the system that performed the build. The build machine is rebooted, and a second build is performed. Optionally, a user is prompted during a grace time period to cancel the corrective action of rebooting the build machine. Optionally, the validation error may be indicated as a product issue, a network issue, or a known limitation in the compiler. Optionally, other corrective actions such as preventing retrying the build and escalating the error may be taken. Optionally, the build may be prevented when the check-in includes code that produced an error on a previous build.

Abstract: Technologies for optimized binary translation include a computing device that determines a cost-benefit metric associated with each translated code block of a translation cache. The cost-benefit metric is indicative of translation cost and performance benefit associated with the translated code block. The translation cost may be determined by measuring translation time of the translated code block. The cost-benefit metric may be calculated using a weighted cost-benefit function based on an expected workload of the computing device. In response to determining to free space in the translation cache, the computing device determines whether to discard each translated code block as a function of the cost-benefit metric. In response to determining to free space in the translation cache, the computing device may increment an iteration count and skip each translated code block if the iteration count modulo the corresponding cost-benefit metric is non-zero. Other embodiments are described and claimed.

Abstract: Different segments of a web page may display multiple values from different fields from a managed component. In dynamic web pages, processing is done in top down order. A web page may have multiple segments. The method uses hidden fields in the web page and a new manager superclass. The manager superclass is extended by a managed component. The managed component is displayed in multiple segments of a web page.

The manger superclass provides getter and setter methods for properties of the visual component. An index is assigned to each segment in the web page. The manager superclass defines a segment index method that allows the managed component to query which of the segments in the web page is active when a getter or setter method is invoked.
