Deprecation warnings are useful only for the developer, not an end user.
Display warnings only when requested using the python -W option. This
stops the display of warnings like:
tools/perf/scripts/python/exported-sql-viewer.py:5102: DeprecationWarning:
an integer is required (got type PySide2.QtCore.Qt.AlignmentFlag).
Implicit conversion to integers using __int__ is deprecated, and
may be removed in a future version of Python.
err = app.exec_()
Since the warning can be fixed only in PySide2, we must wait for it to
be finally fixed there.

The 'Array' class is present in more than one python standard library.
In some versions of Python 3, the following error occurs:
Traceback (most recent call last):

File "tools/perf/scripts/python/exported-sql-viewer.py", line 2658, in __init__
self.buffer = Array(c_char, self.buffer_size, lock=False)
TypeError: abstract class
This apparently happens because Python can be inconsistent about which
class of the name 'Array' gets imported. Fix by importing explicitly by
name so that only the desired 'Array' gets imported.

Add a time chart based on context switch information.
Context switch information was added to the database export fairly
recently, so the chart menu option will only appear if context switch
information is in the database.
Refer to the Exported SQL Viewer Help option for more information about
the chart.

The user probably wants to replace the find text, so select the find
text when the find bar is activated.
That is fairly standard behaviour for search text entry.
Entering text will replace the current text, but using edit keys
(arrows, home, end etc) cancels the selection and enables editing.

pyside2 is the future for pyside support.
Note pyside use Qt4 whereas pyside2 uses Qt5.
Committer testing:
On a system with just:
# rpm -qa| grep -i pyside
python2-pyside-1.2.4-7.fc29.x86_64
#
Running:
$ python ~acme/libexec/perf-core/scripts/python/exported-sql-viewer.py ~/c/adrian.hunter/simple-retpoline.db &
[1] 7438
Makes it use the pyside 1 files:
$ grep -i pyside /proc/7438/maps | cut -d ' ' -f 6- | sort -u
/usr/lib64/libpyside-python2.7.so.1.2.4
/usr/lib64/python2.7/site-packages/PySide/QtCore.so
/usr/lib64/python2.7/site-packages/PySide/QtGui.so
/usr/lib64/python2.7/site-packages/PySide/QtSql.so
$ rpm -qf /usr/lib64/libpyside-python2.7.so.1.2.4
python2-pyside-1.2.4-7.fc29.x86_64
$
To get PySide2 I guess one needs to do:
$ pip install PySide2
But thats a 142MiB download I can't do right now, perhaps before pushing
upstream...

With support for Python 2 or 3 and PySide 1 or 2 (Qt 4 or 5), it is
useful to see what versions are in use. Add an 'About' dialog box that
displays Python, PySide, Qt and database server (SQLite or PostgreSQL)
version numbers.
Committer testing:
$ python ~acme/libexec/perf-core/scripts/python/exported-sql-viewer.py ~/c/adrian.hunter/simple-retpoline.db
Then go to 'Help', then 'About', select all the lines with the mouse
press 'Control+C', then, on the same terminal press control+shift+V
which shows my current environment:
Python version: 2.7.16
PySide version: 1

Add a context menu (right-click) that provides options for copying to

The scripts in scripts/python are intended to be run from 'perf script'
and the Python version used is dictated by how perf was built (PYTHON=).
Also most distros follow pep-0394 which recommends that /usr/bin/python
refer to Python2 and so may not exist on the system (if PYTHON=python3).
- Remove the explicit shebang
- Install the scripts as mode 644
