How to reproduce:
Build skupper-router from the main branch in Debug mode
(-DCMAKE_BUILD_TYPE=Debug) with -DRUNTIME_CHECK=asan
Set env vars to filter out known leak suppressions (use the correct path to the
tests/*.supp files, and the lsan.supp is in BUILD directory!) :
export ASAN_OPTIONS="disable_coredump=0 detect_odr_violation=0
strict_string_checks=1 detect_stack_use_after_return=1
check_initialization_order=1 strict_init_order=1 detect_invalid_pointer_pairs=2
suppressions={*}/home/kgiusti/work/skupper/skupper-router/tests/asan.supp{*}"
export LSAN_OPTIONS="disable_coredump=0
suppressions={*}/home/kgiusti/work/skupper/skupper-router/BUILD/tests/lsan.supp{*}"
Run the skupper router against the attached config file:
skrouterd -c proton-2546.conf &
In a separate window, run curl against the router "curl
[http://127.0.0.1:8000|http://127.0.0.1:8000/];
while curl is running, kill the router: $ kill
That should trigger a leak of the pn_raw_connection.

[jira] [Commented] (PROTON-2546) Leak of raw connection pn_event
[ https://issues.apache.org/jira/browse/PROTON-2546?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=17540999#comment-17540999 ] 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. > Leak of raw connection pn_event > --- > > Key: PROTON-2546 > URL: https://issues.apache.org/jira/browse/PROTON-2546 > Project: Qpid Proton > Issue Type: Bug > Components: proton-c >Affects Versions: proton-c-0.38.0 >Reporter: Ken Giusti >Assignee: Andrew Stitcher >Priority: Major > > See: > [https://github.com/skupperproject/skupper-router/issues/469|https://github.com/skupperproject/skupper-router/issues/469?] > This leak appeared on main about five days ago: > https://github.com/skupperproject/skupper-router/runs/6489086985?check_suite_focus=true#step:26:1757 > > -- This message was sent by Atlassian Jira (v8.20.7#820007) - To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
