NAME ^

MogileFS::Client::CallbackFile

SYNOPSIS ^

    my $mogfs = MogileFS::Client::Callback->new( ... )

    open(my $read_fh, "<", "...") or die ...
    my $eventual_length = -s $read_fh;
    my $f = $mogfs->store_file_from_fh($key, $class, $read_fh, $eventual_length, \%opts);

    $f->($eventual_length, 0); # upload entire file

    $f->($eventual_length, 1); # indicate EOF

DESCRIPTION ^

This package inherits from MogileFS::Client::Async and provides an additional blocking API in which the data you wish to upload is read from a file when commanded by a callback function. This allows other processing to take place on data as you read it from disc or elsewhere.

The trackers, and storage backends, are tried repeatedly until the file is successfully stored, or an error is thrown.

The $key parameter may be a closure. In this case, it is called every time before create_open is called, allowing a different key to be used if an upload fails, allowing for additional paranoia.
