I have a problem that phabricator doesnt map user to svn commit in Diffusion, if the commits are commited before the user is created in phabricator. So the user will not receipt any notification related to that commit. Is there a way to map those commits to the user too. Thanks.
You can request a reparse of the commits from the command line.
bin/repository reparse --all REPO --message
The reparsing will happen in background, so don't expect instant results after the command is run.
