rmw_get_gid_for_publisher reports wrong GID #446

Open noelex opened 1 year ago

Bug report

Operating System:
- Ubuntu 22.04
Installation type:
- binaries
Version or commit hash:
- humble
- rolling
DDS implementation:
- CycloneDDS
Client library (if applicable):
- rcl

Steps to reproduce issue

Create a pulisher and get its GID by calling rmw_get_gid_for_publisher.
Also get GID of the same publisher by using rcl_get_publishers_info_by_topic.

Expected behavior

The GID of the publisher retrieved using either rmw_get_gid_for_publisher or rcl_get_publishers_info_by_topic should be identical.

Actual behavior

rmw_get_gid_for_publisher reports a wrong GID.

Additional information

rmw_get_gid_for_client works as expected. Also no issue with FastRTPS.

Looks like rmw_get_gid_for_publisher is returning pubiid instead of gid, is this expected?
