Hi I have been looking at Poe for some time but now I believe I have an application for it. I would welcome some general feedback on my comments.
Currently we have (a number of) FTP scripts. They each work by sending files sequentially to a remote FTP servers via one of a number of methods. Net::FTP Net::SFTP Net::SFTP::Foreign::Compat I am trying to rationalise these scripts since they are rather in a mess! Each script is called by a different process so in theory we can have multiple copies of the same script running at the same time sending to the same or different FTP servers. I can't work out if Poe would be a suitable alternative. On the one hand, sending files sequentially to the same FTP server would seem to be limited by the throughput of the pipe to the server. Running Poe with multiple processes all trying to use the same pipe should be no faster since we are presumably limited by the pipe bandwidth. On the other hand, if one of the files had a problem and timed out, then other files may not be delayed and could in theory still be transferred (depending upon the reason for the problem). I can see that if I was sending files to different FTP servers then Poe would be of use since then I would be sending files down different pipes, but this is no better that having several processes, one for each server. I have also looked at the FTP components. Poe::Component::Net::FTP I understand that if I were to use the 'put' command then it would block other Poe components until the file was sent. For this reason I would have to use the lower level write command which adds complexity. Has anyone implemented a none-blocking put for this module? Poe::Component::Client::FTP I think this has the same problem, there is no high level put command. I am not yet convinced that for my application Poe is a suitable advantage, but I am willing to be convinced :-) Regards Ian This email is confidential and intended solely for the use of the individual to whom it is addressed.
