- chdir isn't unique to each thread. If you chdir in one thread they all change.
- changing to fork would allow chdir per fork because the memory is copied when forked
- This is an excellent point. You can't pass the full path to put but, you can pass a file handle.
Here is the updated code:
sub worker {
my $tid = threads->tid;
my( $Qwork, $Qresults ) = @_;
my $ftp = Net::FTP->new($gFtpServer, Debug => 0);
$ftp->login($gFtpUser, $gFtpPass) or print "unable to loging to $gF
+tpServer: $ftp->message\n";
while(my $work = $Qwork->dequeue) {
my ($result, $localFile);
my (@workItem);
@workItem = split (",", $work);
chomp($workItem[0]);
chomp($workItem[1]);
chomp($workItem[2]);
print "ftp dir: $workItem[0]\n";
print "local dir: $workItem[1]\n";
print "file: $workItem[2]\n";
$localFile = sprintf("%s%s",$workItem[1],$workItem[2]);
open (my $fh, "<", $localFile) or print "unable to open file";
$ftp->cwd($workItem[0]) or print "unable to FTP change dir $work
+Item[0]: $ftp->message\n";
$ftp->put($fh, $workItem[2]) or print "unable to FTP $workItem[2
+]: $ftp->message\n";
## Process $work to produce $result ##
$result = "$tid : result for workitem ";
$Qresults->enqueue( $result );
}
$Qresults->enqueue( undef ); ## Signal this thread is finished
$ftp->quit;
}
