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