A system and method for determining execution path differences in a computer-implemented software application is provided herein. A software application under analysis is executed at least twice, thereby generating first and second call tree data and associated first and second sets of execution data describing the at least two executions of the software application. This data is then compared to determine a set of differences between the first and second executions of the program, the set of differences comprising one or more nodes that are either called differently in the first and second execution paths or executed differently in the first and second sets of execution data. For each node identified in the set of differences, the first and second call trees are then analyzed to identify at least one parent node that is the root cause of the difference in the execution data.

A specification of a routine name of a root of a call tree and a specification of a desired depth of call tree tracing are obtained. Upon entering a given routine in a program, a determination is made whether the given routine is the root. Responsive to determining that the given one of the routines is the root, trace information for the routine forming the root is output. Furthermore, upon entering a given one of the routines called, directly or indirectly, by the routine forming the root, a determination is made whether the given one of the routines called, directly or indirectly, by the routine forming the root of the call tree is within the desired depth from the routine forming the root of the call tree; and if this is the case, trace information is output for given one of the routines called, directly or indirectly, by the routine forming the root of the call tree.

A method and apparatus for identifying differences in runs of a computer program that are due to changes in the code of the computer program. With the apparatus and method, call trees are generated for two or more builds of a computer program. The apparatus and method perform a “tree-subtract” operation in which the two or more call trees generated during runs of two or more different builds of a computer program are subtracted from one another to identify build to build differences in the execution of the computer program. From the resulting tree, portions of the runs of the different builds of the computer program where the resource utilization of the computer program has not changed are easily identifiable. Moreover, portions of the runs of the different builds of the computer program where there are improvements or regressions in resource utilization of the computer program may be easily identifiable.

A software tool is provided to analyze static source code. Source Code files are selected to define the project work space. A class and a method in the class are selected from said selected source code files. The tool generates a Call Tree as an ordered recursive sequence of all method calls in different classes or their instances that are invoked by said selected method in said selected class. A Sequence Diagram is generated from said Call Tree. The tool remembers all updates to the Call Tree used to generate the Sequence Diagram. This information is used when a generated Sequence Diagram is impacted due to changes made to any source code file included in the project.

Systems and methods are provided for generating a function-relation call tree. For example, an externally-specified global variable name is acquired; whether a first function matches the externally-specified global variable name is inquired; in response to the first function matching the externally-specified global variable name, whether a code of the first function includes a branch-judgment code is determined; in response to the code of the first function including the branch-judgment code, the code of the first function is divided to acquire a pre-branch-judgment code, a branch-judgment code and a post-branch-judgment code; the branch judgment code is analyzed to determine whether a related function is called by a code section associated with an attribute value of the branch-judgment code; and in response to the related function being called by the code section associated with the attribute value of the branch-judgment code, a function-relation call tree between the code section associated with the attribute value and the related function is generated.
