[Clamav-devel] SCANBUFF

2005-02-22 Thread Christian Hilgers 
Hi,

I'm working on an http anti virus scanner. The main goal are continuous and
non-blocking downloads.
Therefore I need libclamav to start scanning even with a small amount of
received data.
I figured out that changing SCANBUFF will work for me. Is there a
disadvantage decreasing this buffer to 25000? I guess it is only a
performance and not a safety issue.

Christian

PS: Is it possible to put my proxy in your Third party software section in
your documentation?
My proxy is called havp http://www.server-side.de/

PSS: I hope this was not too much advertising.

Please do not use cl_scanbuff at all, it's to be removed in 0.90. This
function only supports old type signature scanning and will miss many
viruses (just try to scan test/clam.exe). You should definitely use
cl_scanfile/cl_scandesc instead. Due to performance reasons you can
suggest your users to use a memory based filesystem for proxy file
operations (then also add some option to havp that will allow to set
that directory in libclamav with cl_settempdir())

Yes, of course!

Too bad scanbuff is being retired. I really enjoy
the idea of mem buffer scanning.
Is there any plan to improve and keep it or removal
of it *is* a fact?

I haven't been following clamav development very close
lately, so I don't understand why it only supports old type signature.
Is there an easy answer to that?

 I don't use the scanbuff funktion. I'm using cl_scandesc. I think I
 have to explain thefunctionality of my proxy.   

Sorry, before coffee I was reading mails between lines. You were correct
in your guess, changing the value of SCANBUFF can only affect
performance and not functionality.

Ahh, of course. Maybe I shouldn't have booted windows last night...
