Because such a concept only adds value in a Non-Stop debug session, it is only supported in such a session (see <a href="../faq/index.html#What_is_the_difference_between_Non-stop_and_All-stop_multi-threaded_debugging.3F" class="external text" title="http://wiki.eclipse.org/CDT/User/FAQ#What_is_the_difference_between_Non-stop_and_All-stop_multi-threaded_debugging.3F" rel="nofollow">Non-Stop Debugging</a>). The behavior of a multi-selection Resume/Suspend is as follows: -</p> -<ul><li> Any selected stack frames implies a selection of their corresponding thread. -</li><li> If one or more threads are selected (not processes) and the resume/suspend operation is triggered, each selected thread on which the operation is currently valid will be resumed/suspended. -</li><li> If one or more processes are selected (not threads) and the resume/suspend operation is triggered, each selected process will be resumed/suspended. Resuming/suspending a process implies resuming/suspending each one of its threads on which the operation is currently valid. -</li><li> If both thread(s) and process(es) are selected, and the resume/suspend operation is triggered, each selected process will be resumed/suspended, and each selected thread <b>which is not part of any selected process</b> will be resumed/suspended. The idea is that if a process is being resumed/suspended, each of its threads will be automatically resumed/suspended, and therefore, should not be resumed/suspended a second time because it is also selected. +<ul><li><b>Using the hyper link navigation</b> </li></ul> -<p>As hinted above, CDT takes a permissive approach to multi-select resume/suspend. This means that if a multi-selection includes both stopped and running threads, a resume operation is still allowed, and only the suspended threads will be resumed; similarly, on such a multi-selection, a suspend operation is allowed, and only the running threads will be suspended. -</p> -<h4>Example</h4> -<p><img alt="Image:MultiSelectRunControl.png" src="../images/cdt81/multiselectruncontrol.png" width="602" height="682" border="0" /> -</p><p>In the above screenshot if the user were to press the Resume button with the current multi-selection the following would happen: -</p> -<ol><li> The <i>Consumer</i> process node is selected, therefore the entire process will be resumed. This means that the suspended threads 7 and 9 will be resumed, while threads 6, 8 and 10 will be ignored, as they are already running. -</li><li> Note that the fact that threads 9 and 10 are selected is ignored, as those threads are part of the selected <i>Consumer</i> process, which will be resumed. -</li><li> Stack frames <i>doWork()</i> and <i>work()</i> are selected and belong to thread 4, which becomes implicitly selected in their place. Thread 4 will therefore be resumed. -</li><li> Thread 2 is selected and suspended, and will be resumed. -</li><li> Thread 5 is selected but running, so it will be ignored. -</li></ol> -<p>This feature was completed April 25th, 2012 as part of <a href="http://bugs.eclipse.org/330974" class="external text" title="http://bugs.eclipse.org/330974" rel="nofollow">Bug 330974</a> -</p> -<a name="Show_only_suspended_threads_in_Debug_view"></a><h3> <span class="headline"> Show only suspended threads in Debug view </span></h3> -<p>CDT now has an global preference that allows to only show the suspended threads within the Debug view. When dealing with a large number of threads, a user is typically interested by the threads that are being inspected (suspended ones) and does not care about the running ones. Using this preference, all running threads will not be shown in the Debug view. Note that when a thread is stepping it will remain visible, although it is technically running. The process element of the Debug view will show how many threads are currently being filtered from view. -</p><p>The below example shows the exact same debugging session.

Fast tracepoints use an instruction jump instead of a trap for efficiency. Fast tracepoint need a minimum of space to be inserted in the program and therefore, may fail to be set at certain locations. For fast tracepoints to work, a special library called the in-process agent (IPA), must be loaded in the inferior process. This library is built and distributed as an integral part of gdbserver. Please see the GDB documentation for more details. -</p><p>The user can select between three tracepoint modes in the launch: -</p> -<ol><li><b>Fast</b>: Only use fast tracepoints.

Because such a concept only adds value in a Non-Stop debug session, it is only supported in such a session (see <a href="../faq/index.html#What_is_the_difference_between_Non-stop_and_All-stop_multi-threaded_debugging.3F" class="external text" title="http://wiki.eclipse.org/CDT/User/FAQ#What_is_the_difference_between_Non-stop_and_All-stop_multi-threaded_debugging.3F" rel="nofollow">Non-Stop Debugging</a>). The behavior of a multi-selection Resume/Suspend is as follows: +</p> +<ul><li> Any selected stack frames implies a selection of their corresponding thread. +</li><li> If one or more threads are selected (not processes) and the resume/suspend operation is triggered, each selected thread on which the operation is currently valid will be resumed/suspended. +</li><li> If one or more processes are selected (not threads) and the resume/suspend operation is triggered, each selected process will be resumed/suspended. Resuming/suspending a process implies resuming/suspending each one of its threads on which the operation is currently valid. +</li><li> If both thread(s) and process(es) are selected, and the resume/suspend operation is triggered, each selected process will be resumed/suspended, and each selected thread <b>which is not part of any selected process</b> will be resumed/suspended. The idea is that if a process is being resumed/suspended, each of its threads will be automatically resumed/suspended, and therefore, should not be resumed/suspended a second time because it is also selected. +</li></ul> +<p>As hinted above, CDT takes a permissive approach to multi-select resume/suspend. This means that if a multi-selection includes both stopped and running threads, a resume operation is still allowed, and only the suspended threads will be resumed; similarly, on such a multi-selection, a suspend operation is allowed, and only the running threads will be suspended. +</p> +<h4>Example</h4> +<p><img alt="Image:MultiSelectRunControl.png" src="../images/cdt81/multiselectruncontrol.png" width="602" height="682" border="0" /> +</p><p>In the above screenshot if the user were to press the Resume button with the current multi-selection the following would happen: +</p> +<ol><li> The <i>Consumer</i> process node is selected, therefore the entire process will be resumed. This means that the suspended threads 7 and 9 will be resumed, while threads 6, 8 and 10 will be ignored, as they are already running. +</li><li> Note that the fact that threads 9 and 10 are selected is ignored, as those threads are part of the selected <i>Consumer</i> process, which will be resumed. +</li><li> Stack frames <i>doWork()</i> and <i>work()</i> are selected and belong to thread 4, which becomes implicitly selected in their place. Thread 4 will therefore be resumed. +</li><li> Thread 2 is selected and suspended, and will be resumed. +</li><li> Thread 5 is selected but running, so it will be ignored. +</li></ol> +<p>This feature was completed April 25th, 2012 as part of <a href="http://bugs.eclipse.org/330974" class="external text" title="http://bugs.eclipse.org/330974" rel="nofollow">Bug 330974</a> +</p> +<a name="Show_only_suspended_threads_in_Debug_view"></a><h3> <span class="headline"> Show only suspended threads in Debug view </span></h3> +<p>CDT now has an global preference that allows to only show the suspended threads within the Debug view.

Using this preference, all running threads will not be shown in the Debug view. Note that when a thread is stepping it will remain visible, although it is technically running.
