RingerSelectorTools: thread-checker fixes
A first round of thread-checker fixes for RingerSelectorTools
. See the individual commit messages for details. The only user-visible change is the removal of the ROOT error suppression via gErrorIgnoreLevel
in the write
methods. If it were absolutely needed to
suppress errors, the entire method and all callers would need to be marked as ATLAS_NOT_THREAD_SAFE
. But they only seem to be used in some testing applications.
