xAODRootAccess: thread-safety fixes (!59005) · Merge requests · atlas / athena · GitLab

Frank Winklmeier requested to merge fwinkl/athena:xaodroot into master Dec 05, 2022

Move towards making xAORRootAccess thread-safe:

Split the const-violating TVirtualManager::isSet interface into a const isSet and non-const create interface. (cc @akraszna)
Use ConcurrentStrMap in TStore for cache. (cc @ssnyder)
