This function should be straightforward, and we can remove some trivial logic by moving the functionality of read_events() into __cmd_report() - thus allowing a new session to be properly deleted. Since the 'info' subcommand also needs to process the recorded events, add a 'display_info' flag to differentiate between report and info commands. Furthermore, this patch also calls perf_session__has_traces(), making sure that we don't compare apples and oranges, fixing a segfault when using an perf.data file generated by a different subcommand. ie: ./perf mem record sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.017 MB perf.data (~724 samples) ] ./perf lock report Segmentation fault (core dumped) Signed-off-by: Davidlohr Bueso <davidlohr@hp.com> Cc: Aswin Chandramouleeswaran <aswin@hp.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Hitoshi Mitake <mitake@dcl.info.waseda.ac.jp> Cc: Ingo Molnar <mingo@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/1378693159-8747-5-git-send-email-davidlohr@hp.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
