After freeing the memory used to store the tracing data, this
function has to set the _dataSize field to zero.

This patch implements the Dual Marker used by the KernelShark GUI.
The Dual Marker uses a simple State Machine having only two states
(A and B). In the following patches the State Machine will connect
to the Table and Graph widgets (not introduced yet) and will allow
the user's actions in one of these widgets to have effect in the
other one.

Don't resend this patch (I'm going to just take it). Send a patch on

Hi Steven,
This is one of these cases when I disagree with you.
I don't see anything wrong with the line
l->setFixedWidth(FONT_WIDTH * 16);
or the many other lines in the code which are similar to this one.
It sets the width of the label to be 16 times the width of a typical
character shown by Qt at the particular resolution of your screen.
The line is perfectly self-explanatory. And there is nothing magic in
the number 16. It is just a normal number that everyone can understand
end modify if this is necessary. Why 16? Because I tried different sizes
and I found that this particular one looks nicer to me. If you find this
size ugly, it is absolutist trivial to change it.
Now let's look in the alternative that you suggest (if I understand
correctly):
l->setFixedWidth(DUAL_MARKER_TOOLBAR_LABEL_WIDTH);
This line is a magic word, because it tells you absolutist nothing about
the actual size of this label. And if we apply this rule everywhere, we
will need a ton of macros, with very long and in the same time very
similar names. This will also make the geometry of the GUI completely
hard-coded and will eliminate any possibility of making these sizes
configurable via the Json I/O.
I do not believe in "general rules". Each rule has a field of
applicability. When you program GUIs you need to apply fine tuning. I
don't think we can avoid this.
Thanks!

Also be careful about extre whitespace. There's a extra space at the
end of the above line.
(I removed it in the commit).

The above is rather ugly. Again, just have another patch on top that
converts this to:
if ((freeSpace = viewSize - tableSize) > 0) {
_view.setColumnWidth(nColumns - 1, _view.columnWidth(nColumns - 1) +
freeSpace - 2);
/* Just a little bit less space.

This patch defines the class KsGraphModel which provides a model for
visualization of trace data. This class is a wrapper of kshark_trace_histo
and is needed only because we want to use the signals defined in
QAbstractTableModel (a class inherited by KsGraphModel).

To: rostedt@goodmis.org; +Cc: linux-trace-devel@vger.kernel.org, Yordan Karadzhov
From: Yordan Karadzhov (VMware) <y.karadz@gmail.com>
This patch defines widget for interactive visualization of trace data
shown as time-series. The provides an info panel and a graph plotting
area (KsGLWidget). The panel and the plotting area are integrated with
the Dual Marker.

From: Yordan Karadzhov (VMware) <y.karadz@gmail.com>
The KsSession class provides instruments for importing/exporting
the state of the different components of the GUI from/to Json
documents. These instruments are used to save/load user session
in the GUI.

The KsMainWindow class provides the Main window for the KernelShark
GUI. It implements the frame used by the two trace data viewing areas
(Graphs and Table) together withe the system of menus, used to perform
different actions.

From: Yordan Karadzhov @ 2018-10-16 15:53 UTC (permalink / raw)
To: rostedt@goodmis.org; +Cc: linux-trace-devel@vger.kernel.org
A helper function for launching a "File exists" dialog is added to
KsWidgetsLib. This function asks the user, before overwriting an existing
file. The "File exists" dialog function is used by the KsMainWindow widget
when saving the configuration of the filters and sessions.

To: rostedt@goodmis.org; +Cc: linux-trace-devel@vger.kernel.org
This problem was reported by Steven Rostedt. The reason for having
the problem was my wrong assumption that for a given task the
sched_switch event is always the last record before the task is
preempted.
The patch changes two things:
It modifies the "match" functions used to search for sched events,
making these functions to trigger only on sched_switch/_wakeup events.
This eliminates the flakiness due to the fact that sometimes the
sched_switch can happend to be in the same bin with some of the trailing
events from the same task. This also has the side effect of simplifying
the code.
It introduces a second pass over the data, which is task-specific and
gets executed only the first time the task is plotted. This second pass
edits the "pid" field of the last trailing event making it equal to the
"next pid" field of the sched_switch event.

This patch defines a dialog to be used for trace data recording.
The dialog has two main areas: a Control panel and a terminal-like
widget for monitoring the recording process.

BTW, this also works:
CYAN='\e[36m'
PURPLE='\e[35m'
NC='\e[0m' # No Color
Which is a little cleaner.
If you agree, can you resend just this patch with the update (as v2)?
Thanks!

A Record dialog is added to the Tools menu of the KernelShark GUI.
The Record dialog can be used only after installing the project
(sudo make install).

The Record dialog requires Root privileges in order to be able to collect
tracing data. However graphical applications cannot be run as root on
Wayland. The problem is worked around by wrapping the kshark-record
executable in a shell script which checks the XDG_SESSION_TYPE and in
the case of Wayland, allows the root user to access the running
X server.
