Data flow analysis for dynamic application, skipping views

Embodiments of the present invention provide a method and system for finding uninitialized variables outside the local scope. Initially, a source code of a program is received. The source code may include multiple functions. A checked scope is determined for at least one variable in the source code. The checked scope includes a local scope. Additionally, the local scope is accessed using at least one function call of the functions. Static analysis is run, covering the checked scope for the at least one variable in the source code. At least one inter-procedural dependency is identified to determine whether the at least one variable in the local scope is uninitialized. Responsive to determining that the at least one variable in the local scope is uninitialized the at least one variable is displayed to a user.

Finding uninitialized variables outside the local scope

Techniques for representing a finite state machine forming are described herein. The techniques include a method that identifies screens of a computing program. The method may include correlating the identified screens with states of a finite state machine. Events indicating transition between the identified screens may be determined as well as data flow associated with the events. The method may include forming a graph representing the screens, events, and data flow in the finite state machine.

Obtaining a dynamic download policy for a mobile application being executed on the mobile computing device, wherein the dynamic download policy indicating a download policy for a data item, the download policy is defined by the dynamic download policy as enabled in a first device context of the mobile computing device. During execution of the mobile application, a current device context of the mobile application is being monitored. In response to the mobile application attempting to download the data item and in response to the current device context being the first device context, the download policy may be enforced.

Dynamic download policy for mobile applications

Methods, storage systems and computer program products implement embodiments of the present invention that include receiving, by a computer, source code for an application, the source code including multiple instructions to be executed in a single thread. A first static analysis is performed on the application source code in order to identify a given instruction including an asynchronous handler, and a plurality of entry points to the application. Based on the static analysis, an order of execution of the multiple instructions is determined, and an intermediate representation is generated that includes the multiple instructions arranged in the determined order of execution. In some embodiments, a second static analysis can be performed on the intermediate representation that can identify an anti-pattern in the intermediate representation, and then correct the anti-pattern in the source code.
