-# MASSIVE FIXME
-# we can't really lock based on DSN, as we do not yet have a way to tell that e.g.
-# DBICTEST_MSSQL_DSN=dbi:Sybase:server=192.168.0.11:1433;database=dbtst
-# and
-# DBICTEST_MSSQL_ODBC_DSN=dbi:ODBC:server=192.168.0.11;port=1433;database=dbtst;driver=FreeTDS;tds_version=8.0
-# are the same server
-# hence we lock everything based on sqlt_type or just globally if not available
-# just pretend we are python you know? :)
-
-
- # when we get a proper DSN resolution sanitize to produce a portable lockfile name
- # this may look weird and unnecessary, but consider running tests from
- # windows over a samba share >.>
- #utf8::encode($dsn);
- #$dsn =~ s/([^A-Za-z0-9_\-\.\=])/ sprintf '~%02X', ord($1) /ge;

-
- # provide locking for physical (non-memory) DSNs, so that tests can
- # safely run in parallel. While the harness (make -jN test) does set
- # an envvar, we can not detect when a user invokes prove -jN. Hence
- # perform the locking at all times, it shouldn't hurt.
- # the lock fh *should* inherit across forks/subprocesses
- #
- # File locking is hard. Really hard. By far the best lock implementation
- # I've seen is part of the guts of File::Temp. However it is sadly not
- # reusable. Since I am not aware of folks doing NFS parallel testing,
- # nor are we known to work on VMS, I am just going to punt this and
- # use the portable-ish flock() provided by perl itself. If this does
- # not work for you - patches more than welcome.
