Re #126: and why isn't there a way to have locking to prevent anything but
the process doing the scribbling from changing the item?

Right now it does
chmod(file, read-writable)
fp= fopen(file,"r+");
chmod(file, only-readable)
and then goes on to do it's reading and writing. The window of vulnerability
is between the two chmods, and it's a pretty short window. I can't lock it
until after I've opened it, but I suppose I could open it read-only, apply
an advisory lock, chmod it, open it read-write, chmod-it and close the
read-only file handle. Hardly seems worth the effort though. Not sure if
it would work with all the different locking libraries we support.

I voted to close the scribble log t everyone but staff. I would vote
against getting rid of the scribble command entirely.

Re #132: But you could call a suid program.

Re #129: I suspect that if you decide you care, the fix might be to have
item frozenness marked by something other than unix permissions.

I agree with the last, except that I have to maintain compatibility with
Picospan, which is essentially inalterable.

Is mdw lurking on this, or will/can he weigh in?

Even if Picospan is unalterable, couldn't one make whatever method
backtalk uses to expurgate/scribble frozen items available to telnet
and dialup users as well? Code it as a standalone suid program.

Something like this will probably happen.

chmod 600 /bbs/censored
Amazing how much it took to get 23 characters typed.

What does the passing of this motion do to Backtalk's function:
View hidden response.

Hi Joe.
Backtalk and Picospan have two degrees of erasure. Their names for them
differ:
PICOSPAN BACKTALK
expurgate hide Don't display the response by default
scribble erase Erase the response
Expurgate was originally called 'censor' but the command name was mostly
changed in the early days of Grex, though the old one leaks through here
and there.
The discussion here has been entirely about the scribble/erase commands.
They now remove text in such a way that nobody but staff can ever see
them again.
The expurgate/censor/hide command has always been just a way to flag the
response to say "you can see this if you want to, but you probably don't
want to". Backtalk even lets you post a response in a hidden state.
Backtalk's "view hidden response" link only appears for "hidden"
responses, not erased responses. It has never been possible to view
erased responses via Backtalk.
