===============================
This program is copyrighted to Patrik Nilsson. Everybody may use this
program as long as:
* Sending me an email at "patrik.nilsson@mbox3.swipnet.se" telling
that you are using this program, when you find it useful.
(I do not promise to reply...)
* You are using it at your own risk.
SHORT:
=====
tcpdl is a program to download files from http hosts. Files to be
downloaded is listed in a file called "tcpdldir:urllist". There are
an example coming with this package.
LONG:
=====
TO START:
========
1. You have to assign "tcpdldir:" anywhere.
(i.e. "assign tcpdldir: work:tcpdldir"
2. Make sure that tcpdldir:urllist exists.
3. Run "startnet" (amitcp)
4. run "tcpdl" from a shell
see also: "testtcpdl", a script coming with this package.
WINDOW:
======
The window is updated every 3rd second (downloading has got a higher
priority).
--cut--
Status Time CPS CSize FSize Request (2685/2927)
--cut--
WINDOW/Status:
==============
What is going on?
"Connecting" Trying to connect a host.
"ERROR" An error detected.
"Sending" Sending request.
"Header" Receiving header.
"Updating" Requesting using "If-Modified-Since" from a host or
loading data from tcpdldir:data/.
"OK" Okej.
"Receiving" Receiving data.
"Wait. html" A limit of 512k html-data to process. Will continue
when below limit.
"Proc. html" Processing html.
"Copying" Copying html-file from t: to tcpdldir:http/
WINDOW/Time:
============
Time since trying to connect.
WINDOW/CPS:
===========
CPS
WINDOW/CSize:
=============
Size of data received.
WINDOW/FSize:
=============
Size of data, if available in header.
WINDOW/Request:
===============
Request string.
WINDOW/(2685/2927):
===================
example: 2685 is number of request done.
2927 is number of requests in memory.
OTHER NOTES:
===========
It uses "t:" for temporary files. (When processing html-files.)
The program requires about one megabyte to run and 500-1000 bytes for
each request.
You can always break the program using CTRL+C. The program exits as fast
as possible, breaking all downloadings. (It can be a while if processing
large htmlfiles - those processes are not broken.)
Filenames that is not a valid amigados-name is replaced with a crc-checksum.
i.e.: http://www.cs.uit.no/~kjelli/thor.html would be
tcpdldir:http/www.cs.uit.no/_kjelli_CRC_BDF5F321/thor.html
The program reties every request 5 times, each of them have a timeout of
about 20 seconds until connected and then 60 seconds. If the download fail
the request is not repeated.
THE "TCPDLDIR:URLLIST"-FILE:
===========================
The file contains: a request-string (url) at left, one (or more) space(s)
and then flags for the download.
http://host/path/ D2 H3 IMG TEXT
http://www.sds.se D5 H0 IMG
the flags can be:
D1, D2, ..., D19 downloading n levels of text/html
H0, H1, ..., H5 If an other host is refered by a HREF
max number of levels is set to n.
DEFAULT H0; current host only.
P0, P1, ..., P5 If path is other than given in your urllist
max number of levels is set to n.
DEFAULT <number of Dn levels>
IMG download IMG-files (pictures at html)
TEXT download text-files (accept: text/*)
ALL download all types of files (accept: */*)
UPDATE If this flag does not exists, the program
does not request this file if at harddisk.
If "UPDATE" exists and file is at harddisk
the request contains "If-Modified-Since".
(Date sent, when using this, is the same
coming with header.
see "tcpdldir:data/http/" )
example:
=======
You have found kjelli's homepage (thor). You would download everything he
has got at his page.
http://www.cs.uit.no/~kjelli/thor.html D19 P0 IMG ALL
This will download his html-file for two levels and get his fiends homepages.
http://www.cs.uit.no/~kjelli/thor.html D2 P1 IMG
OFFLINE-READING (MOSAIC):
========================
run "amitcp:amitcp" as command
double click at mosaic icon and then open menu "local host". Get a file
from i.e. "tcpdldir:http/www.cs.uit.no/_kjelli_CRC_01234567/thor.html
Thanks:
======
This will be edit as soon as possible.
HISTORY:
=======
v1.00
First public release.
---
v1.01
Bugs:
* TAB-problem, fixed.
* Enforcer hits fixed.
New:
* Didn't know about "port" in "http://host:port/path"
* The program reties every request 4 times, each of them have a timeout of
about 10 seconds until connected and then 30 seconds. If the download fail
the request is not repeated.
---
v1.02
* Now using xen.font 8 if available at disk, else using default font
meaning the text wouldn't fit in its window.
Bug:
* "Port" v1.01 didn't work. I hope this will. I didn't test it:(
* More TAB-problems, fixed.
New:
* For safe: if a host fails more than 10 times this host is not
called any more. This task has a priority of -2, which means that
everything that is more important is done before this.
changed:
The program reties every request 5 times, each of them have a timeout of
about 10 seconds until connected and then 60 seconds. If the download fail
the request is not repeated.
---
v1.03
Rewrote loop "Infotoprocess".
changed:
The program retries every request 5 times, each of them have a timeout of
about 20 seconds until connected and then 60 seconds. If the download fails
the request is not repeated.
The program requires about one megabyte to run and 500-1000 bytes for
each request.
---
v1.04
Now to check about "HTTP/1.0 200 " in the header. (If the request is not
alright the "tcpdldir:data/http/" is not written.)
