Bo 22-Jan-2007 [6905] | Volker, this definitely seems like it could be the issue. |
Volker 22-Jan-2007 [6906] | can you add some wait between files in your code, to give it time to relax? just guessing. |
Bo 22-Jan-2007 [6907x2] | Smooth-Copy has an adjustable wait mechanism built in, but it may make the overall length of the transfer too long. I'll have to put some debugging statements in prot-ftp.r to see if I can isolate the problem and figure out how to go around it. |
Thanks for the help you have given so far! | |
Volker 22-Jan-2007 [6909x2] | np |
Pleae tell when you find out where it hangs. Curious :) | |
Bo 22-Jan-2007 [6911x2] | If I find a solution, I'll post the fix and let you know. |
Yup, just verified that Rebol always hangs up when the FTP server logs a 425 response: "425 Can't open data connection" | |
Bo 23-Jan-2007 [6913x2] | I've found THE LINE that Rebol hangs up on when the FTP server returns a 425 response. It is the line with the ;<--- after it below: accept-connect: func [port type][ if not port/locals/passive [ either port/locals/listen-port [ if type <> 'new-dir [ port/sub-port: first port/locals/listen-port ;<--- ] close-listen port port/locals/listen-port: none ][ net-utils/accept-proxy port/sub-port ] ] ] |
Obviously, it is in an infinite wait for a listen port that will never come. Can you see any problems if the line were changed to: if port? lstn-prt: wait [any [system/schemes/ftp/timeout system/schemes/default/timeout 30] port/locals/listen-port][port/sub-port: lstn-prt] | |
Volker 23-Jan-2007 [6915] | there should be a timeout, yes. Would trigger an error too, how is that done in the right way with ports? Because i do not know what this code does without a port/subport. what confuses me, this code runs also in passive mode? an idea of mine is to listen on both ports, control and this one. if the server sends the 405, its never processed because we dont listen there. Should listen on both ports and still handle commands. But do not know what the right vars are. Waiting for the skilled ftp-patchers before examining^^ |
Bo 23-Jan-2007 [6916] | In limited testing, my patch above (slightly modified to remove typos) works. If the 425 occurs, after a timeout period the patched protocol picks up right where it left off. But yes, I would really like the skilled ftp-patchers to take a look at the problem and see if they can come up with a better fix. |
Volker 23-Jan-2007 [6917] | Grats :) |
sqlab 24-Jan-2007 [6918] | Are you sure that this happens in passive mode, despite " if not port/locals/passive [ " I found this line also to be the cause for infinite waiting when using ftp with active mode thru a firewall . But activating the passive mode eliminated the need for a patch on my side. |
Graham 24-Jan-2007 [6919x2] | Anyone got a quick script I can use to determine the ip address of a PC on the local network? |
I presume I need one server script and one client script | |
Rebolek 24-Jan-2007 [6921] | Graham: do you mean IP adress of your computer? >> read dns:// == "boleslavb967" >> read dns://boleslavb967 == 10.10.8.179 |
Graham 24-Jan-2007 [6922x3] | no |
I just get 127.0.0.1 when i do that. | |
it's a virtual nic ... | |
Rebolek 24-Jan-2007 [6925] | then I'm afraid I don't know :/ |
Graham 24-Jan-2007 [6926x3] | maybe there's some linux command that will tell me |
like windows ipconfig | |
ifconfig :) | |
Volker 24-Jan-2007 [6929x2] | there was a script which lists all the available interfaces. bBsed on 'get-modes IIRC. But forgot where i saw it. |
IIRC Robert and the author where chatting once, maybe he remembers? | |
Bo 24-Jan-2007 [6931] | sqlab: I'm double-checking my code... |
Anton 26-Jan-2007 [6932] | get-modes tcp:// 'interfaces |
Graham 26-Jan-2007 [6933] | works nicely |
Robert 26-Jan-2007 [6934] | Is it possible to get the MAC address as well? |
Anton 26-Jan-2007 [6935] | I don't think I've ever seen it directly in rebol. |
Henrik 26-Jan-2007 [6936] | I think that would be a security hole. |
Pekr 26-Jan-2007 [6937x2] | why? |
just run ipconfig /all via shell and parse it out ;-) | |
Volker 26-Jan-2007 [6939] | The ultimate cookie |
Henrik 29-Jan-2007 [6940] | ok, is this bad? Rebol/View under OSX: >> stats == -741616872 |
Graham 29-Jan-2007 [6941x2] | Has anyone got an overview of how the internet protocols work? |
Jeff wrote an article on custom protocol handler .... are there any other tutorials around? | |
Anton 29-Jan-2007 [6943] | Check Chris' stuff in the Sandbox group. |
PeterWood 29-Jan-2007 [6944] | This thread may help a little: http://www.rebol.org/cgi-bin/cgiwrap/rebol/ml-display-thread.r?m=rmlHBNQ |
Graham 29-Jan-2007 [6945] | Thanks. |
Gabriele 29-Jan-2007 [6946] | henrik, unless rebol is using more than 2gb, i guess there must be something wrong :) |
Oldes 29-Jan-2007 [6947] | Henrik: it seems to be very bad. But it looks that OSX will not be such a bad OS if it allows you work even with apps eating so much memory. |
Henrik 29-Jan-2007 [6948x2] | it took some time to swap things back into memory. the script was working just fine though. |
I had a rugby script running all night that would periodically download 1 MB of data from another machine. I guess there was a leak. :-) | |
Oldes 29-Jan-2007 [6950] | I don't think it's fine if your script need so much memory:) |
Henrik 29-Jan-2007 [6951] | but it still ran instead of crashing. I think that's good, but isn't stats in need of a fix if it can't display mem usage above 2 GB? |
Oldes 29-Jan-2007 [6952x2] | that's because rebol don't have unsigned integers |
and probably nobody was expecting, someone will need so much memory | |
Ladislav 29-Jan-2007 [6954] | BACK versus past-tail indices. Every index (except for 1) may become past-tail during the execution of a script (when its block/string "shrinks") and "legal" again (when its block/string grows sufficiently). Let me mention the SAME? function as an example of a consistent behaviour - no matter whether the index is past-tail or not, the SAME? function takes it into account when comparing series. The BACK function, however, handles past-tail indices differently than the "normal" ones. any wishes/notes/proposals? |
