Info

Setting Group Focus Setting Group Focus TotalView has two types of groups: process groups and thread groups. Process groups only contain processes, and thread groups only contain threads. The threads in a thread group can be drawn from more than one process. Topics in this section are: � “Specifying Groups in P/T Sets” on page 263 � “About Arena Specifier Combinations” on page 264 � “‘All’ Does Not Always Mean ‘All’” on page 267 � “Setting Groups” on page 268 � “Using the g Specifier: An Extended Example” on page 269 � “Merging Focuses” on page 271 � “Naming Incomplete Arenas” on page 272 � “Naming Lists with Inconsistent Widths” on page 273 TotalView has four predefined groups. Two of these only contain processes, while the other two only contain threads. TotalView also lets you create your own groups, and these groups can have elements that are processes and threads. The following are the predefined process groups: � Control Group Contains the parent process and all related processes. A control group includes children that were forked (processes that share the same source code as the parent) and children that were forked but subsequently called the execve() function. Assigning a new value to the CGROUP (dpid) variable for a process changes that process’s control group. In addition, the dgroups –add command lets you add members to a group in the CLI. In the GUI, you use the Group > Custom Groups command. � Share Group Contains all members of a control group that share the same executable. TotalView automatically places processes in share groups based on their control group and their executable. You can’t change a share group’s members. However, the dynamically loaded libraries used by group members can be different. The following are the predefined thread groups: � Workers Group Contains all worker threads from all processes in the control group. The only threads not contained in a worker’s group are your operating system’s manager threads. 262 Chapter 13: Using Groups, Processes, and Threads
Setting Group Focus � Lockstep Group Contains every stopped thread in a share group that has the same PC. TotalView creates one lockstep group for every thread. For example, suppose two threads are stopped at the same PC. TotalView creates two lockstep groups. While each lockstep group has the same two members, they differ in that each has a different TOI. While there are some circumstances where this is important, you can usually ignore this distinction. That is, while two lockstep groups exist if two threads are stopped at the same PC, ignoring the second lockstep group is almost never harmful. The group ID value for a lockstep group differs from the ID of other groups. Instead of having an automatically and transient integer ID, the lockstep group ID is pid.tid, where pid.tid identifies the thread with which it is associated. For example, the lockstep group for thread 2 in process 1 is 1.2. In general, if you’re debugging a multi-process program, the control group and share group differ only when the program has children that it forked with by calling the execve() function. Specifying Groups in P/T Sets This section extends the arena specifier syntax to include groups. If you do not include a group specifier, the default is the control group. For example, the CLI only displays a target group in the focus string if you set it to something other than the default value. You most often use target group specifiers with the stepping commands, as they give these commands more control over what’s being stepped. Use the following format to add groups to an arena specifier: [width_letter][group_indicator][pid][.tid] This format adds the group_indicator to what was discussed in “Specifying Processes and Threads” on page 259. In the description of this syntax, everything appears to be optional. But, while no single element is required, you must enter at least one element. TotalView determines other values based on the current focus. TotalView lets you identify a group by using a letter, number, or name. A Group Letter You can name one of TotalView’s predefined sets. Each set is identified by a letter. For example, the following command sets the focus to the workers group: dfocus W TotalView Users Guide: version 8.7 263
