db_export__deferred() deferred the export of comms if the comm string had
not been "set" (changed from :<pid>) however that problem was fixed a long
time ago by commit e803cf97a4f9 ("perf record: Synthesize COMM event for a
command line workload"), so get rid of db_export__deferred().Signed-off-by: Adrian Hunter <[email protected]> --- tools/perf/util/db-export.c | 61 +------------------ tools/perf/util/db-export.h | 2 - .../scripting-engines/trace-event-python.c | 4 +- 3 files changed, 2 insertions(+), 65 deletions(-) diff --git a/tools/perf/util/db-export.c b/tools/perf/util/db-export.c index 2182f552aac6..f36970018df3 100644 --- a/tools/perf/util/db-export.c +++ b/tools/perf/util/db-export.c @@ -19,70 +19,14 @@ #include "call-path.h" #include "db-export.h" -struct deferred_export { - struct list_head node; - struct comm *comm; -}; - -static int db_export__deferred(struct db_export *dbe) -{ - struct deferred_export *de; - int err; - - while (!list_empty(&dbe->deferred)) { - de = list_entry(dbe->deferred.next, struct deferred_export, - node); - err = dbe->export_comm(dbe, de->comm); - list_del(&de->node); - free(de); - if (err) - return err; - } - - return 0; -} - -static void db_export__free_deferred(struct db_export *dbe) -{ - struct deferred_export *de; - - while (!list_empty(&dbe->deferred)) { - de = list_entry(dbe->deferred.next, struct deferred_export, - node); - list_del(&de->node); - free(de); - } -} - -static int db_export__defer_comm(struct db_export *dbe, struct comm *comm) -{ - struct deferred_export *de; - - de = zalloc(sizeof(struct deferred_export)); - if (!de) - return -ENOMEM; - - de->comm = comm; - list_add_tail(&de->node, &dbe->deferred); - - return 0; -} - int db_export__init(struct db_export *dbe) { memset(dbe, 0, sizeof(struct db_export)); - INIT_LIST_HEAD(&dbe->deferred); return 0; } -int db_export__flush(struct db_export *dbe) -{ - return db_export__deferred(dbe); -} - void db_export__exit(struct db_export *dbe) { - db_export__free_deferred(dbe); call_return_processor__free(dbe->crp); dbe->crp = NULL; } @@ -171,10 +115,7 @@ int db_export__comm(struct db_export *dbe, struct comm *comm, comm->db_id = ++dbe->comm_last_db_id; if (dbe->export_comm) { - if (main_thread->comm_set) - err = dbe->export_comm(dbe, comm); - else - err = db_export__defer_comm(dbe, comm); + err = dbe->export_comm(dbe, comm); if (err) return err; } diff --git a/tools/perf/util/db-export.h b/tools/perf/util/db-export.h index e8a64028a386..261cfece8dee 100644 --- a/tools/perf/util/db-export.h +++ b/tools/perf/util/db-export.h @@ -68,11 +68,9 @@ struct db_export { u64 sample_last_db_id; u64 call_path_last_db_id; u64 call_return_last_db_id; - struct list_head deferred; }; int db_export__init(struct db_export *dbe); -int db_export__flush(struct db_export *dbe); void db_export__exit(struct db_export *dbe); int db_export__evsel(struct db_export *dbe, struct perf_evsel *evsel); int db_export__machine(struct db_export *dbe, struct machine *machine); diff --git a/tools/perf/util/scripting-engines/trace-event-python.c b/tools/perf/util/scripting-engines/trace-event-python.c index 112bed65232f..c9837f0f0fd6 100644 --- a/tools/perf/util/scripting-engines/trace-event-python.c +++ b/tools/perf/util/scripting-engines/trace-event-python.c @@ -1620,9 +1620,7 @@ static int python_start_script(const char *script, int argc, const char **argv) static int python_flush_script(void) { - struct tables *tables = &tables_global; - - return db_export__flush(&tables->dbe); + return 0; } /* -- 2.17.1
