Bug fix for mcChannelNumber AODFix (!22411) · Merge requests · atlas / athena

Matthew Gignac requested to merge matthewgignac/athena:21.2-mcChannelNumBugFix into 21.2 Apr 04, 2019

Hi,

This merge request fixes a bug in the xAODEventInfoCnv::EventInfoRunNumberFixAlg algorithm used during the mcChannelNumber AODFix for buggy samples produced in the EVNT-to-EVNT workflow. The issue with the mentioned algorithm was found that the original EventInfo was copied before setting the store, and therefore the output EventInfo lacked the aux variables of the original EventInfo that we copied. The fix simply rearranges the the code to set the store before copying the original EventInfo.

This issue is currently a blocker for derivation requests in 21.2.55.0 and beyond.

The bug was discussed here: https://its.cern.ch/jira/browse/ATLASG-1493

Cheers, Matthew
