Subject[PATCH 5.4 108/109] perf scripts python: exported-sql-viewer.py: Fix unexpanded Find result
Date
From: Adrian Hunter <adrian.hunter@intel.com>

commit 3a3cf7c570a486b07d9a6e68a77548aea6a8421f upstream.

Using Python version 3.8.2 and PySide2 version 5.14.0, ctrl-F ('Find')
would not expand the tree to the result. Fix by using setExpanded().

Example:

$ perf record -e intel_pt//u uname
Linux
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.034 MB perf.data ]
$ perf script --itrace=bep -s ~/libexec/perf-core/scripts/python/export-to-sqlite.py perf.data.db branches calls
2020-06-26 15:32:14.928997 Creating database ...
2020-06-26 15:32:14.933971 Writing records...
2020-06-26 15:32:15.535251 Adding indexes
2020-06-26 15:32:15.542993 Dropping unused tables
2020-06-26 15:32:15.549716 Done
$ python3 ~/libexec/perf-core/scripts/python/exported-sql-viewer.py perf.data.db

Select: Reports -> Context-Sensitive Call Graph or Reports -> Call Tree
Press: Ctrl-F
Enter: main
Press: Enter

Before: line showing 'main' does not display

After: tree is expanded to line showing 'main'
