perf scripts python: exported-sql-viewer.py: Fix zero id in call tree 'Find' result
Using ctrl-F ('Find') would not find 'unknown' because it matches id zero. Fix by excluding id zero from selection. 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 -> Call Tree Press: Ctrl-F Enter: unknown Press: Enter Before: displays 'unknown' not found After: tree is expanded to line showing 'unknown' Fixes: ae8b887c00d3f ("perf scripts python: exported-sql-viewer.py: Add call tree") Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: stable@vger.kernel.org Link: http://lore.kernel.org/lkml/20200629091955.17090-6-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
