* change namespace indentation to 0Tim Moore2009-12-211-263/+263
| | | | | A silly change, but this works better with other tools, like git diff. I should have started the C++ files this way.
* grapher: implement restarting a stap processTim Moore2009-12-111-0/+18
| | | | | | | | | | | | | | | | | | | * grapher/StapParser.cxx (StapParser::disconnect): new function * grapher/StapParser.hxx (StapProcess::StapProcess): initialize argv to 0 * grapher/grapher.cxx (StapLauncher::setArgs): Set argv to 0 (StapLauncher launch, launchUsingParser): Refactor launch(), extracting function a that (re)launches a stap process using an existing parser. (StapLauncher::onChildDied): call disconnect() on dead parser. (GrapherWindow::_graphicalLauncher, setGraphicalLauncher): delete member, replacing with... (graphicalLauncher): new variable (ProcModelColumns): Store parser object in the list model instead of just a StapProcess object. (ProcWindow::onRestart): new function (ProcWindow::refresh): Preserve the list selection when the process list is refreshed. (ProcWindow::onSelectionChanged): Manage the restart button's state.
* grapher: integrate graph events from stdin with the stap process framework.Tim Moore2009-12-101-11/+20
| | | | | | | | | | | | | | | This was the original way to do graphing and had bitrotted some. * grapher/StapParser.cxx (initIO): new catchHUP argument (ioCallback): Only disconnect signals, etc. on IN_HUP if catchHUP is true. (errIoCallback): Write error messages to stderr, not stdout. * grapher/grapher.cxx (StapLauncher::launch): Don't catchHUP on our stap process children. (ProcWindow::refresh): Display something reasonable for the stap "process" that is feeding stdin. (main): Use StapParser::initIO to initialize parser reading from stdin.

(initIo): New function (parsers, parserListChangedSignal): new variables * grapher/StapParser.cxx (ioCallback): disconnect signals when child dies (initIo): new function * grapher/grapher.cxx (StapLauncher): eliminate death callback in favor of childDied signal.

* grapher: start of a dialog for displaying active stap processesTim Moore2009-12-081-3/+9

* refactor list of data sets out of GraphWidget into a global data structure.Tim Moore2009-12-081-2/+4
| | | | | | | | | | | | | | Also, add a sigc signal for broadcasting data set changes. * grapher/GraphData.hxx (GraphDataList) new typedef (getGraphData, graphDataSignal): new functions * grapher/Graph.hxx (DatasetList): remove typedef in favor of systemtap::GraphDataList * grapher/GraphWidget.cxx (GraphWidget, onGraphDataChanged): Use graphDataSignal to notice new data sets that need to be added. Use the global data set list instead of one embedded in GraphWidget. * grapher/StapParser.hxx: delete the _widget member; use signals to broadcast that there are new data sets instead of calling into the widget.
* add copyright and license to grapher filesTim Moore2009-12-071-0/+8

| | | | | | | | | | | | | | This is accompanied by support for multiline output in hover text. * grapher/StapParser.cxx (ioCallback): Read data 'til the end of line character, not just '\n'.
