server=192.168.0.101;port=10308;database=dbic_test;driver=FreeTDS;tds_ve rsion=8.0. So this one longs right, yes? Show quoted text

This one also looks right, yes? Show quoted text

server=192.168.0.101;port=10308;database=dbic_test;driver=FreeTDS;tds_ve rsion=8.0. I imagine you find this one strange because no "Use of uninitialized value $x" and yet you do get "Issuing rollback" - yes? Martin -- Martin J. Evans Wetherby, UK

Apparently the DBD::ODBC connection was a red herring: rabbit@Thesaurus:~$ perl -MDBI -e '$SIG{__WARN__} = sub { print "warning\n" }; { my $sth = DBI->connect("dbi:SQLite::memory:", undef, undef, { AutoCommit => 0})->do ("SELECT 1") }' warning rabbit@Thesaurus:~$ perl -MDBI -e 'local $SIG{__WARN__} = sub { print "warning\n" }; { my $sth = DBI->connect("dbi:SQLite::memory:", undef, undef, { AutoCommit => 0})->do ("SELECT 1") }' Issuing rollback() due to DESTROY without explicit disconnect() of DBD::SQLite::db handle :memory:. rabbit@Thesaurus:~$ perl -MDBI -e 'local $SIG{__WARN__} = sub { print "warning\n" }; { my $sth = DBI->connect("dbi:SQLite::memory:", undef, undef, { AutoCommit => 0})->do ("SELECT 1") } delete $SIG{__WARN__}' warning

My bad, the reason not everyone saw the problem was because of RT#62371. With that out of the way however the problem persists: rabbit@Imladris:~$ perl -MDBI -e '$SIG{__WARN__} = sub { print "warning\n" }; { my $sth = DBI->connect("dbi:SQLite::memory:", undef, undef, { AutoCommit => 0, PrintWarn => 1 })->do ("SELECT 1") }' warning rabbit@Imladris:~$ perl -MDBI -e 'local $SIG{__WARN__} = sub { print "warning\n" }; { my $sth = DBI->connect("dbi:SQLite::memory:", undef, undef, { AutoCommit => 0, PrintWarn => 1 })->do ("SELECT 1") }' Issuing rollback() for database handle being DESTROY'd without explicit disconnect(). rabbit@Imladris:~$ perl -MDBI -e 'local $SIG{__WARN__} = sub { print "warning\n" }; { my $sth = DBI->connect("dbi:SQLite::memory:", undef, undef, { AutoCommit => 0, PrintWarn => 1 })->do ("SELECT 1") } delete $SIG{__WARN__}' warning

This is not really a DBI problem, it is a perl idiosyncrasy. Closing this ticket, further explanation can be found here: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?p=dbsrgits/DBIx-Class.git;a=commitdiff;h=8e9b9ce5f997bb8f90a56ecfee9b96b0f5b6ff9d#patch2

Interesting. Note that perl 5.13.<mumble> has a new optimization that'll remove the "1;" at compile time. So you may need a different dummy statement. Tim.

Re-closing. Got reopened accidentally.
