NAME DBIx::AutoReconnect - restart DBI calls after reconnecting on failure DESCRIPTION The module wraps "DBI->connect" call with "DBIx::AutoReconnect->connect" call so that any operation with DB connection handle that fails due to connection break ( server shutdown, tcp reset etc etc), is automatically reconnected. The module is useful when a little more robustness is desired for a cheap price; the proper DB failure resistance should of course be inherent to the program logic. SYNOPSIS use DBIx::AutoReconnect; my $dbh = DBIx::AutoReconnect-> connect( "dbi:Pg:dbname=template1", "postgres", "password", { PrintError => 0, ReconnectTimeout => 5, ReconnectFailure => sub { warn "oops!" }, }, ); USAGE "DBIx::AutoReconnect" contains a single method "get_handle" that returns underlying DBI handle, returned from "DBI->connect()". The module-specific knobs that can be directly assigned to the object handle, are described below ReconnectFailure &SUB Called when "DBI->connect" call fails. ReconnectTimeout $SECONDS Seconds to sleep after reconnection attempt fails. Default: 60 ReconnectMaxTries $INTEGER Max number of tries before giving up. The connections are tried indefinitely if "undef". Default: 5 NOTES Transactions are not restarted if connection breaks, moreover, "begin_work", "rollback", and "commit" die when called, to protect from unintentional use. To use transactions, operate with the original DBI handle returned by "get_handle". "AutoCommit" is allowed though. "RaiseError" is mostly useless with this module, because the DBI errors that may raise the exception, are all wrapped in eval by the connection detector code. The only place where it is useful, is when "ReconnectMaxTries" tries are exhausted, and depending on "RaiseError", the code dies or returns "undef" from the call. SEE ALSO DBI, DBIx::Abstract.
