Valgrind was complaining about a memory leak in this function. From looking at similar code in libosinfo itself, it appears we ought to be unrefing a lot more references here. This error started happening after the new 'test-phony-win2k25.sh' was added, but it seems to be unrelated to the test itself and must have been a pre-existing problem that was exposed by the test. ==2959521== ==2959521== HEAP SUMMARY: ==2959521== in use at exit: 43,662,865 bytes in 1,194,159 blocks ==2959521== total heap usage: 3,898,497 allocs, 2,704,338 frees, 2,609,865,939 bytes allocated ==2959521== ==2959521== 353 (40 direct, 313 indirect) bytes in 1 blocks are definitely lost in loss record 2,661 of 3,422 ==2959521== at 0x52BFAEC: g_type_create_instance (gtype.c:1929) ==2959521== by 0x52A48B3: g_object_new_internal.part.0 (gobject.c:2606) ==2959521== by 0x52A5EFD: g_object_new_with_properties (gobject.c:2603) ==2959521== by 0x52A6F30: g_object_new (gobject.c:2415) ==2959521== by 0x121A52: v2v_osinfo_os_find_os_by_short_id (libosinfo-c.c:166) ==2959521== by 0x2DEE12: caml_c_call (in /home/rjones/d/virt-v2v/v2v/virt-v2v) ==2959521== by 0x6F4D7BF: ??? ==2959521== by 0x6F5543F: ??? ==2959521== ==2959521== LEAK SUMMARY: ==2959521== definitely lost: 40 bytes in 1 blocks ==2959521== indirectly lost: 87 bytes in 5 blocks ==2959521== possibly lost: 0 bytes in 0 blocks ==2959521== still reachable: 1,976,140 bytes in 98 blocks ==2959521== suppressed: 35,544,294 bytes in 1,133,259 blocks ==2959521== Reachable blocks (those to which a pointer was found) are not shown. ==2959521== To see them, rerun with: --leak-check=full --show-leak-kinds=all ==2959521== ==2959521== For lists of detected and suppressed errors, rerun with: -s ==2959521== ERROR SUMMARY: 1 errors from 1 contexts (suppressed: 10 from 10) --- mltools/libosinfo-c.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/mltools/libosinfo-c.c b/mltools/libosinfo-c.c index 11df1fe..00d74c1 100644 --- a/mltools/libosinfo-c.c +++ b/mltools/libosinfo-c.c @@ -164,17 +164,22 @@ v2v_osinfo_os_find_os_by_short_id (value dbv, value osv) os_list = osinfo_db_get_os_list (OsinfoDb_t_val (dbv)); filter = osinfo_filter_new (); - osinfo_filter_add_constraint (filter, OSINFO_PRODUCT_PROP_SHORT_ID, String_val (osv)); + osinfo_filter_add_constraint (filter, OSINFO_PRODUCT_PROP_SHORT_ID, + String_val (osv)); list = osinfo_list_new_filtered (OSINFO_LIST(os_list), filter); if (osinfo_list_get_length (list) == 0) { g_object_unref (list); + g_object_unref (filter); + g_object_unref (os_list); caml_raise_not_found (); } os = OSINFO_OS(osinfo_list_get_nth (list, 0)); rv = Val_OsinfoOs_t (dbv, os); g_object_unref (list); + g_object_unref (filter); + g_object_unref (os_list); CAMLreturn (rv); } -- 2.49.0
