Subject: Run the entire test suite under replicated SQLite on DBICTEST_VIA_REPLICATED
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=8b60b9211a;hp=7d6c28b70b4c37d6296ea4a17ac919799b3a8bc2;p=dbsrgits%2FDBIx-Class.git

Run the entire test suite under replicated SQLite on DBICTEST_VIA_REPLICATED

There isn't real replication, the reader and writer in fact talk to the same
on-disk file. Still this is effective enough to put into CI.
