From bb49c4af2e973bf785d3c30f843ec13929f65688 Mon Sep 17 00:00:00 2001 From: Josh Brobst Date: Thu, 4 Jul 2024 23:39:44 -0400 Subject: [PATCH] tracemalloc: Fix tracebacks memory leak The tracemalloc_tracebacks hash table has traceback keys and NULL values, but its destructors do not reflect this -- key_destroy_func is NULL while value_destroy_func is raw_free. Swap these to free the traceback keys instead. --- Python/tracemalloc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/Python/tracemalloc.c b/Python/tracemalloc.c index fee7dd0e56d96d..e58b60ddd5e484 100644 --- a/Python/tracemalloc.c +++ b/Python/tracemalloc.c @@ -838,7 +838,7 @@ _PyTraceMalloc_Init(void) tracemalloc_tracebacks = hashtable_new(hashtable_hash_traceback, hashtable_compare_traceback, - NULL, raw_free); + raw_free, NULL); tracemalloc_traces = tracemalloc_create_traces_table(); tracemalloc_domains = tracemalloc_create_domains_table();
