perf scripts python: exported-sql-viewer.py: Fix warning display

2021-06-03T06:59:00Z

commit f56299a9c998e0bfbd4ab07cafe9eb8444512448 upstream. 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.

perf scripts python: exported-sql-viewer.py: Fix Array TypeError

2021-06-03T06:59:00Z

commit fd931b2e234a7cc451a7bbb1965d6ce623189158 upstream. 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 4702, in reports_menu.addAction(CreateAction(label, "Create a new window displaying branch events", lambda a=None,x=dbid: self.NewBranchView(x), self)) File "tools/perf/scripts/python/exported-sql-viewer.py", line 4727, in NewBranchView BranchWindow(self.glb, event_id, ReportVars(), self) File "tools/perf/scripts/python/exported-sql-viewer.py", line 3208, in __init__ self.model = LookupCreateModel(model_name, lambda: BranchModel(glb, event_id, report_vars.where_clause)) File "tools/perf/scripts/python/exported-sql-viewer.py", line 343, in LookupCreateModel model = create_fn() File "tools/perf/scripts/python/exported-sql-viewer.py", line 3208, in self.model = LookupCreateModel(model_name, lambda: BranchModel(glb, event_id, report_vars.where_clause)) File "tools/perf/scripts/python/exported-sql-viewer.py", line 3124, in __init__ self.fetcher = SQLFetcher(glb, sql, prep, self.AddSample) 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.

Export switch events to a new table 'context_switches' and create a view 'context_switches_view'. The table and view will show automatically in the exported-sql-viewer.py script. If the table ends up empty, then it and the view are dropped.
