NAME

Net::Download::Queue - Download files with one or more workers.

SYNOPSIS

# *** In the app which needs to download files
use Net::Download::Queue;
my $oQueue = Net::Download::Queue->new() or die;
my $oDownload = $oQueue->oDownloadAdd(
    "http://www.darserman.com/Perl/TexQL/texql.pl",
    "./downloads",
    "texql.pl.txt",
    $urlReferer,      #Optional
) or die;
#The url is now queued


# *** Or using the command line
download_queue --url=http://www.darserman.com/Perl/TexQL/texql.pl \
    --dir=./downloads --file=texql.pl.txt --
#The url is now queued



# *** On another command line (you can have many of these)
download_queue --process
#Urls are downloaded as they appear in the queue

DESCRIPTION

Download files asynchronously in a queued fashion.

Your application (or a CLI script) can add files to the queue, and other workes will process the queue and actually download the files.

METHODS

new()

Create new queue.

oDownloadAdd($url, $dirDownload, $file, [$urlReferer = ""])

Add $url to the queue, to be downloaded in $dirDownload/$file.

Return the new Download object on success, else die.

oDownloadDequeue()

If there is any pending download in the queue, return a Download object, or return undef if there are no pending downloads.

The Download object is now in "downloading" state.

Die on errors.

requeueDownloading()

Set any downloads in status "downloading" back into status "queued".

Die on errors.

percentComplete()

Return the percent 0..100 how complete the download of all current downloads are.

If none is current, that's 100% complete.

Die on errors.

CLASS METHODS

rebuildDatabase()

Empty and rebuild the SQLite database.

Return 1 on success, else die on errors.

ensureDatabase()

Rebuild the SQLite database if it's not present.

Return 1 on success, else die on errors.

SEE ALSO

I haven't found any modules that perform the downloads asynchronously.

KNOWN BUGS

Ther is a race condition when dequeueing a Download from the queue. Should run in a transaction.
