Hello e people.
I think i got a memory leak using e_connman. Everytime i plug/unplug a network cable on one of my network cards, dbus sends messages about it. But everytime its done, it seems to leak some bytes. How to reproduce : - go to trunk/e_dbus/src/bin/ - run e_dbus_connman0_7x_test - Plug/Unplug multiple times your network card Here is what valgrind tells me : kuri[@]Jetdail(15:41:02)[~/Apps/e17/e_dbus/src/bin] $ valgrind --leak-check=full --trace-children=yes ./e_dbus_connman0_7x_test ---------------------- Cutted useless info ---------------------- ^CDBG: clean exit. ==14947== ==14947== HEAP SUMMARY: ==14947== in use at exit: 25,641 bytes in 159 blocks ==14947== total heap usage: 7,095 allocs, 6,201 frees, 2,282,863 bytes allocated ==14947== ==14947== 144 bytes in 1 blocks are definitely lost in loss record 38 of 61 ==14947== at 0x4C27024: calloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==14947== by 0x5267BE4: _ecore_signal_call (ecore_signal.c:325) ==14947== by 0x5268134: _ecore_signal_received_process (ecore_signal.c:127) ==14947== by 0x5261916: _ecore_main_loop_iterate_internal (ecore_main.c:1842) ==14947== by 0x5261D9E: ecore_main_loop_begin (ecore_main.c:887) ==14947== by 0x402F41: main (e_dbus_connman0_7x_test.c:1714) ==14947== ==14947== 2,304 (864 direct, 1,440 indirect) bytes in 12 blocks are definitely lost in loss record 56 of 61 ==14947== at 0x4C27024: calloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==14947== by 0x5B69956: _dbus_pending_call_new_unlocked (dbus-pending-call.c:109) ==14947== by 0x5B5A4EE: dbus_connection_send_with_reply (dbus-connection.c:3379) ==14947== by 0x4E34A1B: e_dbus_message_send (e_dbus_message.c:67) ==14947== by 0x5042C13: e_connman_element_message_send (e_connman_element.c:1159) ==14947== by 0x5042EE0: e_connman_element_call_full (e_connman_element.c:1189) ==14947== by 0x5042FF1: e_connman_element_sync_properties_full (e_connman_element.c:1396) ==14947== by 0x504571E: _e_connman_element_item_register (e_connman_element.c:469) ==14947== by 0x5045954: _e_connman_element_iter_get_array (e_connman_element.c:1261) ==14947== by 0x5046879: _e_connman_element_property_changed_callback (e_connman_element.c:2318) ==14947== by 0x4E3762D: cb_signal_dispatcher (e_dbus_signal.c:272) ==14947== by 0x4E33593: e_dbus_filter (e_dbus.c:419) ==14947== ==14947== LEAK SUMMARY: ==14947== definitely lost: 1,008 bytes in 13 blocks ==14947== indirectly lost: 1,440 bytes in 48 blocks ==14947== possibly lost: 0 bytes in 0 blocks ==14947== still reachable: 23,193 bytes in 98 blocks ==14947== suppressed: 0 bytes in 0 blocks ==14947== Reachable blocks (those to which a pointer was found) are not shown. ==14947== To see them, rerun with: --leak-check=full --show-reachable=yes ==14947== ==14947== For counts of detected and suppressed errors, rerun with: -v ==14947== Use --track-origins=yes to see where uninitialised values come from ==14947== ERROR SUMMARY: 57 errors from 27 contexts (suppressed: 4 from 4) So the problem seems to be that in “e_dbus_message_send()”, “pending” gets allocated, and ends up getting queued in element->_pending.properties_get by “e_connman_element_sync_properties_full” in “e_connman_element.c” and then it is never freed. I don't know if the problem is e_connman, or the test program because i lack knowledge to understand the situation.
