NAME

EDG::WP4::CCM::Fetch::Download

DESCRIPTION

Module provides methods to handle the retrieval of the profiles.

Functions

  • retrieve

Stores $url into $cache if it’s newer than $time, or if $self->{FORCE} is set.

It returns undef in case of error, 0 if it there were no changes on the remote server since $time (the server returned a 304 code) and a CAF::FileWriter object with the downloaded contents if they had to be downloaded.

Should be called ony by download.

  • download

Downloads the files associated with $type (profile). In case of error it retries $self->{RETRIEVE_RETRIES} times, falling back to a failover URL if necessary (thus up to 2*$self->{RETRIEVE_RETRIES} may happen.

Returns undef (or dies) in case of error, or the result from retrieve method otherwise:

  • 0 if nothing had to be retrieved (files in the server were older than our local cache)

  • a CAF::FileWriter object with the downloaded contents, if something was actually downloaded
