[REBOL] Re: Rebol and FTP (recursive stuff in particular)

From: mat:eurogamer at: 14-Dec-2000 16:40

Heya Holger, HK> No, REBOL caches and reuses the FTP control connection across HK> subsequent accesses to the same host and directory. But doesn't actually close any. Is there a way of forcing them closed? How are you supposed to implement some sort of recursive system with high-level FTP when Rebol tries to open as many threads as their are directories? Clearly the concurrent user limit for the site will be hit, to say nothing of the fact this is not efficient to say the least. HK> A new data HK> connection has to be created for each file being transfered. That HK> is not a limitation of REBOL, but rather a requirement of the FTP HK> protocol. Indeed, but it's the control connection which is limited on servers. HK> The only situation when REBOL creates a new control HK> connection is when you change directories. That is necessary because HK> FTP provides no standard way to remotely navigate through the HK> directory tree (in particular up the tree) without side effects. What, other than cd .. ? I don't get it. Assuming for a second that I buy this argument, and I'm really not sure I do, then how would you recommend a recursive directory scan be implemented in Rebol? -- Mat Bettinson - EuroGamer's Gaming Evangelist with a Goatee http://www.eurogamer.net | http://www.eurogamer-network.com
