CodeDynamics 2018.1

New exec and fork handling controls

New with 2018.1, CodeDynamics allows you to control how fork(), vfork(), clone() (when used without the CLONE_VM flag), and execve() system calls are handled by the debugger. Using new command line options or CLI state variables, users can now define if the debugger should stop the process, continue the process or ask whether or not to stop the process when the fork’d or exec’d process is acquired into the CodeDynamics debugging session. For example, to configure CodeDynamics such that when "bash" calls exec, the process will automatically be continued (no questions asked), but have CodeDynamics ask when other processes exec, use the following dset CLI command or codedynamics command option:

dset TV::exec_handling {{{^bash$} go} {. ask}}

codedynamics -exec_handling '{{^bash$} go} {. ask}'

Above, the <regexp> was wrapped in an extra set of curly braces to make sure that Tcl did not process the "$" as a variable reference. Setting up fork_handling rules work similar.

See the TV::exec_handling and TV::fork_handling command line option and state variable documentation in the CodeDynamics Reference Guide for more information.

New user interface improvements

Whether you are using CodeDynamics or TotalView’s new user interface, activated through the Display Preferences panel or using the -newUI command line option, there are several great enhancements to the new user interface that will make debugging your applications even easier. If you have any feedback about the new user interface, requests for new or missing features or any problems please send email to tv-beta@roguewave.com.

Multiple Data Views
The Data View is used to explore variables and debug data in your program. To better manage the display of your data multiple Data Views can now be created by simply clicking the “duplicate view” icon in the toolbar of the Data View. A new Data View will be created and any selected items in the original Data View will be cloned into the new one.

Data View Informational Drawer Tab
To find out more information about an expression and your data in the Data View, a Drawer has been added to the view with a new Information tab. The Information tab displays the expression, scope, thread, type, address, language and other information for the selected item in the Data View. The size of the Drawer is easily adjusted by clicking on the grab bar and moving it up or down. Double clicking on the grab bar will snap it open or closed.
