[REBOL] ftp dowlnoad of large file and read-io ....

From: petr::krenzelok::trz::cz at: 12-Sep-2001 13:23

Hi, So I just rewrote core.pdf example of ftp download of large file, and it doesn't work, unless I clear the buffer each time. What am I doing wrong? buf-size: 20000 buffer: make string! buf-size source: open/direct ftp-site target: open/new/direct join target-path [trim fl/text ".tra"] total: 0 size: 0 start: now/time while [not zero? size: read-io source buffer buf-size][ write-io target buffer size clear buffer total: total + size p/text: to-string total t/text: to-string now/time - start show p show t ] The problem is, that if I don't "clear buffer", the download of each file stops at some 20479, and server probably closes the connection. It even doesn't matter, if I define buffer as binary type, of size buf-size + 2 (btw: what is that additional 2 good for?) Everything seems to work, once I add "clear buffer" line as above. The question is - what is going on? Thanks a lot, -pekr-
