Hi,

I'm trying to make an existing DBI::Proxy-using GUI-app. more robust by trying to make it recover from a network failure. Right now I'm puzzled by a 'broken pipe' message I get on the client-side when I break the network connection between client and server. After this message the app. stops, I can't seem to catch this with an 'eval'. The code is something like: 

  my $retval = eval {
      $sth->execute(@values);
  };
  unless ($retval) {
      _db_recover();
  }

  ...
sub _db_recover {
   eval {
      $dbh->disconnect();
   };
   warn("reconnecting to database in 20 seconds\n");
   sleep 20;
   eval {
      $dbh->connect(@somevalues);
   };
}

Note this is still in development, I don't want to reconnect everytime the execute fails.

I've also tried to change the signal-hash locally to 'IGNORE' the $SIG{PIPE} and $SIG{DIE} signals (in fact I've even tried to set the values of the whole %SIG to 'IGNORE') but the app. still stops executing.

While debugging I found DBD::Proxy holds an IO::Socket that gets disconnected when I disconnect the network connection (duh), this most probably causes the 'broken pipe' message, but I can't bend my mind around how to access this Socket or how to recreate it after a network failure.

Any idea's on how I can keep my app. (at least) running in these situations?

Update: fixed $dbh->execute to $sth->execute

In reply to script dies with 'broken pipe'-message, even in eval by eXile
