DBIx::Admin::DSNManager manages a file of DSNs, for both testing and production.
|
|
|
|
The INI-style format was selected, rather than, say, using an SQLite database,
|
|
so that casual users could edit the file without needing to know SQL and without
|
|
having to install the command line program sqlite3.
|
|
|
|
Each DSN is normally for something requiring manual preparation, such as
|
|
creating the database named in the DSN.
|
|
|
|
In the case of SQLite, etc, where manual intervention is not required, you can
|
|
still put the DSN in dsn.ini.
|
|
|
|
One major use of this module is to avoid environment variable overload, since it
|
|
is common to test Perl modules by setting the env vars $DBI_DSN, $DBI_USER and
|
|
$DBI_PASS.
|
|
|
|
But then the problem becomes: What do you do when you want to run tests against
|
|
a set of databases servers? Some modules define sets of env vars, one set per
|
|
database server, with awkward and hard-to-guess names. This is messy and
|
|
obscure.
|
|
|
|
DBIx::Admin::DSNManager is a solution to this problem.
