Other APM vendors make a trade-off between data quality and scale - sampling transactions and sacrificing metadata or depth in the
call stack in order to support large environments.
Version 3.6 of XJTAG adds views of the
call stack and of the currently-set breakpoints to the XJEase debugger in XJDeveloper, completing its debugging capabilities by enabling a view of the stack of functions which have been called to get to the current point in the code, and allowing the user to easily view and remove breakpoints from the code.
1) The
call stack when the allocating API was invoked, denoted as set {alloc_[stack.sub.i] | i [member of] [0, [n.sub.alloc]]}.
The new tool includes the improved source navigation; go to definition, combined profiler with the JavaScript
call stack and timeline and profiler for CPU sampling.
Other new features include: enhanced autoscripting with Intellisense; open and heterogeneous database support; enhanced debugging features such as tracepoints and the ability to run to a specified function on the
call stack, as well as popup windows to enable easy display of variables and property values of PowerBuilder and .NET objects.
Other topics include memorized forward computation of dynamic slices,
call stack coverage for GUI test suite reduction, the relationship between software assertions and faults, and model simulation for test execution capacity estimation.
* Full Issue and incident logging details (incl allocation, time/date, description,
call stack info etc)
The second condition is a slight simplification of the rules for subroutines defined in Lindholm and Yellin [1996], which do allow a subroutine to return more than one level up in the implicit subroutine
call stack in certain cases, but does match the definitions presented in Sarti and Abadi [1999].
This is one reason that modern dialects of Lisp which are compiled as well as interpreted, such as Common Lisp, are lexically scoped.) In evaltrace diagrams, the nesting of contours accurately reflects the structure of the
call stack of an interpreter, with the innermost contour being the top of the stack and the global contour at the bottom.
