[Samba] Execute on file access

[sp...@itserv.de]

Hi Samba-Folks,

it might be a feature request, it might the the proof that I'm too stupid
to find it in the documentation:

I'd like to execute a binary program on each file which gets stored or
modified on the samba server. Is that possible?

I'd like to store images on a samba server, and from each image stored a
thumbnail should be calculated. Thus, after a file is created/modified, I
need to call a program passing the path name of the stored/modified file
as a parameter.

You might as well think about calling a virus scanner on the file just
stored.

I know that this might be a performance issue, but that will be my problem
- not yours :-)

Thank you for your replies,

Peter

Write a VFS module that connects to the close operation.

Simple enough! Yes, give me two or three minutes, and I'll be done. ;-)

Open Source makes everybody a brilliant programmer, true?

However, thank you for your answer, which reads to a non-programmer like
me as: "no, that feature is missing".

Yep. Feel free to look at http://samba.org/samba/support/ to
find someone do it for you :-)

You always have the option to purchase programmer time to implement
a feature like that. On closed source systems "no, that feature is missing"
would be your only answer until enough people complained or the
company providing the software went out of business.
