Subject: [OSSTEST PATCH 1/2] Executive database: set isolation level in Perl
Date: Wed, 30 Nov 2016 14:30:08 +0000	[thread overview]
Message-ID: <1480516209-26048-1-git-send-email-ian.jackson@eu.citrix.com> (raw)

The Perl was lacking SET TRANSACTION ISOLATION LEVEL SERIALIZABLE,
which is sadly not the default.  Currently that does not matter
because of all the table locking, but we are about to abolish that.
