* Fix regression in statistic operationsAnton Vorontsov2009-12-091-6/+12
| | | | | | | | | | | In commit 98c783852039061db8c1611742660aaded0eab77 ("Use proper types for do_div") I imprudently changed some variables to an unsigned type while in some places the code actually relies on a sign. So, let's be a bit smarter now and use temporary variables. Reported-by: Wenji Huang <wenji.huang@oracle.com> Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This avoids having humongous numbers displayed on the graphs' x axis. Also, the dialog for adding a data set to a graph was cleaned up. * grapher/graph-dialog.glade: Add check box for display of relative time and a label for the data set list. Force the list of data sets to be larger. * grapher/Graph.hxx (_timeBase): new member * grapher/Graph.cxx (draw): Subtract _timeBase from displayed time value. * grapher/GraphWidget.hxx (DataModelColumns): Add a column for a data set's title, which is optional at the moment. * grapher/GraphWidget.hxx (_globalTimeBase, _timeBaseInitialized, _relativeTimesButton, _displayRelativeTimes): new members * grapher/GraphWidget.hxx (GraphWidget): Hook up check button for displaying relative time. (on_expose_event): Determine base time if needed; set base time in graphs. (onDataDialogOpen): Insert graph data set's name (key) and title into the list of data sets.

* support multiline data output from scripts run under the grapherTim Moore2009-12-045-20/+66
| | | | | | | | | | | | | | 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'. Be careful to use I/O functions that don't treat '\n' specially. * grapher/StapParser.hxx: ditto * grapher/CairoWidget.cxx (CairoTextBox::draw): Perform line breaks for hover text. * testsuite/systemtap.examples/general/grapher.stp: Do multiline output of keyboard events.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | do_div accepts unsigned 64-bit integer type for dividend, signed types would cause do_div's typecheck fail: stat-common.c: In function 'needed_space': stat-common.c:50: error: comparison of distinct pointer types lacks a cast ...same errors in time.c and tapset-timers.cxx's generated code... A fix for time.c is special, on ppc32 cycles_t is 32-bit, so technically we don't need do_div, but since the whole _stp_gettimeofday_ns() operates on 64-bit types we'd better be safe and use uint64_t for the math.
