[Tutor] file overwrite

Wed, 2 Jan 02:41:52 2002 -0500

OK, I found 2 ways of turning a big number into a string, and It is a
working program- except:

It stores the entire subject line in the pending file. OK, but it
OVERWRITES previous entries, so there is always only one, the
lastone! Everything else works fine.

Here is the program listing:

ns# list TLcommander.py

directory:/www/www.howlermonkey.net/cgi-bin

import os, sys, string, cgi, random, time, smtplib      # We will use
some functions from these
msg=""                                          #initiate msg as a
null string.
domainname='howlermonkey.net'                   # this is our domain
name, edit to suit

path2lists=path2bin+'lists/'                    # this is where the
lists live
CRLF="\r\n"                                     # this is used a lot
in the forming of headers later.
#10
form = cgi.FieldStorage()
nowNUMBER = time.time()                         # thie returns a 9
tuple numberic expression
timestamp=hex(int(nowNUMBER))                   # turn that time
number into a string!
command = form["command"].value                 # of the time this
script runs.
to_addr = form["email"].value
listname = form["listname"].value
print 'Content-Type: text/html'+CRLF            # HTML is following

print '</head><body bgcolor="FFFFFF" text="000000"

print 
if not (form.has_key("email") and form.has_key("listname") and
form.has_key("command")):
        print "<P><center><H1>Error</H1></center><P>"
        print 'Something is wrong with how you filled out your form
data; I am confused.'
        print 'POSSIBLY there was a transmission error, or a typo?'
        print "Please ensure that you fill in all 3 data fields.(one
is a radio button)."
        print "Nonsense or fraudulent information will result in"
        print "your request being discarded by a robot, unread."
        print "click [BACK] and try again. Thank you."
        print '-Tiny.<P><br></body></html>'     #30
        sys.exit()      
else:
        print '<P><br><center><h2>Submitted request
information</h2></center>'
        print '<P><br><hr width=60% align="center"><P>'
        print "Declared EMail:", to_addr,'<br>'
        print "Requested LIST:", listname,'<br>'
        print "Issued Command:", command,'<p>'
        print '<hr width=60% align="center"><P><br>'
        print "A email is being sent to you with these pieces of
information in the Subject."

        print "For most clients, simply replying to it is sufficent.
The body is ignored,"
        print "only the headers and subject line matter. The Letter
itself explains what"
        print "is happening, and what to do. IN breif, reply to the
message; just click"
        print "[REPLY] and then [SEND] (however your email client
names them)."
        print "<P>"
        print "If you change your mind before doing so, simply delete
the letter."
        print "<P><br>"
        print "Respectfully,"
        print "-Tiny the list robot.<P><br></body></html>"

# keep that above line blank!
subject = command + " " + listname + " " + timestamp
f1=open('./lists/pending','w')          # open the pending file

msg=msg + """
To whom it may concern;
Someone (could be you) recently tried to """ + command + """ this
email address to
the email list:""" + listname + """. If you want this to happen,
simply reply
to this letter; do not alter the subject line. Don't worry about your
EMail program sticking a "Re:" in front of the subject material, I
know
how to handle that. My training is FAIL-SAFE; if a message is invalid
or
makes no sense, I simply throw it away and do nothing.

If you do NOT want this to happen, just delete this letter and it's
over. I
clean up dead pendings once a day when they are more than 7 days old,
so a
week from now all record of this will vanish.

IF there is any problem, please feel free to contact the postmaster:
mailto:postmaster@"""+domainname+"""?Subject=List%20Service%20Inquiry
should
work nicely.

Respectfully,

welcome your
