[16608] Fix total_unread_ consistent with reader's history upon get_first_untaken_info() by Mario-DL · Pull Request #3203 · eProsima/Fast-DDS

Mario-DL · 2023-01-11T12:01:58Z

Description

mp_reader->nextUntakenCache() in get_first_untaken_info() is removing the change (it->remove_change()) if matched_writer_lookup() returns false. This, in turn calls change_removed_by_history() but get_last_notified() returns always false in that case because no writerGUID is found, hence a sequence number of 0.0 is returned.

This situation causes that total_unread_ is not decremented despite removing the change, so the history size and total_unread_ variable are inconsistent and the issue arises.

When user calls take_next_sample(), Ret::NO_DATA is returned despite reader->get_unread_count() is different from 0.

Proposed solution

get_first_untaken_info() should be a read-only API and mp_reader->nextUntakenCache() should not be called from inside because it modifies the history in certain cases.

@Mergifyio backport 2.8.x 2.7.x 2.6.x
