When we use plain 'perf buildid-list' we use only what is in the buildid table in the perf.data header. And those have absolute pathnames because at 'perf record' time we used __perf_session__process_events and that doesn't sets up the path shortening code in map__new() that happens if symbol_conf.full_paths is false, the default. On the other hand, when we use 'perf buildid-list --with-hits' we process all the events using perf_session__process_events, adding entries to the global DSO list _after_ removing the current directory from the DSO name, for presentation purposes. Because of that we end up having two entries in the DSO list when recording events for binaries using relative pathnames. Fix it minimally by setting symbol_conf.full_paths to true when marking the DSOs with hits in 'perf buildid-list --with-hits', as used by 'perf archive' Right fix longer term is to shorten the path only at presentation time. Will be done for 2.6.36. Reported-by: Stephane Eranian <eranian@google.com> Tested-by: Stephane Eranian <eranian@google.com> Cc: David S.
