This release of this art suite uses
This release serves as the ROOT-6 companion release to art 1.17.07–i.e. the features shared between the two versions are nearly identical, modulo the ROOT5 vs. ROOT6 difference. For that reason, the new features, bug fixes, and known issues listed below are a copy of those shown here. Although the feature sets are nearly the same,
art1.18.05 relies on a newer version of
fhiclcpp, which takes advantage of
cetlib improvements that were not supported in
Compile-time improvements (as documented here):
- Support #11485: It was observed that adding a feature to the
fhiclcppproducts sizably increased the build time and libraries that depend on those products. In particular, inlined use of the
stdregular-expression library utilities in header files resulted in larger than desired compile times and library sizes. The uses of inline
std::regexinvocations have been moved to their own source files, thus avoiding the code bloat. It is possible that execution of the affected functions is now slower than when inlining was used. However, the affected functions are called within
artonly during system initialization. Users who depend on heavy use of the
fhiclcpplibrary within the
artevent loop (not recommended) may notice longer execution times.
