Ken Giusti commented on PROTON-2546:
------------------------------------
I've been debugging this a bit and think that the pn_raw_connection is being
leaked.
-----------------------------------------------------
Suppressions used:
count bytes template
*2 3072 ^pn_raw_connection$*
6 384 sys_mutex
390 408014 /libpython3.*.so
-----------------------------------------------------
SUMMARY: AddressSanitizer: 896 byte(s) leaked in 18 allocation(s).
I can reproduce these leaks by shutting down the skupper-router while there is
at least one active pn_raw_connection. I shut down the router by sending a
SIGTERM to it via kill. In this case the router does not attempt to call
pn_raw_connection_close() and wait for the disconnect. Instead the shutdown
code calls pn_proactor_free() and expects any outstanding raw connection memory
to be freed by that.
Is this assumption correct?
If no raw connections are present at shutdown these leaks do not occur.
