RE: Howto: user-level permissions on Windows?

It depends what sort of access restrictions you want. I don't believe
you can limit the read access on a folder by folder basis, but you can
limit the ability to commit to certain folders.
What you need to do is create a pre-commit hook for the repository in
question. This will then check the user performing the commit, check the
files being committed, and only allow the process to continue if the
user has access to all the relevant folders. There is mention of this in
the documentation, and an example Perl script that does exactly what you
want in the SVN repository.
Unfortunately, all the examples are based on Unix/Linux, which can
actually run Perl properly - unlike Windows. So for the benefit of and
Windows users out there....
Firstly, you need to install a Perl interpreter on the SVN server
machine, such as http://www.activestate.com/Products/ActivePerl/
You then need to place the attached batch file into the hook
sub-directory of the repository to be controlled, changing the
references to drives and the script location accordingly. You'll notice
that a number of files get created to the root of G: in my case. This is
necessary because Perl on Windows cannot fork the look process
correctly. So I got round the problem getting the batch file to create
these temporary files, which the Perl script can then read.
You then need to place the attached Perl script into the directly that
matches the call from the batch file. This is basically the same script
provided as an example with the SVN source code, but with changes to
read the temporary file and work under Windows
Last step. You now need to create the file that holds the security
information. Unfortunately, I've removed all the comments from my file,
but it's fairly straight forward to work out the format. Create a file
in the root of the repository to be protected called
commit-access-control.cfg. In this file, you can create a number of ini
sections with the following format
   [unique name]
   match = sed_style_matching_string
   users = user1
   users = user2
   access = read-write or read-only
Here's a few entries from my cfg file
[Global Read-Only]
match = .*
access = read-only
[Give administrators global access]
match = .*
users = jbutlin
access = read-write
[Allow writing to the Installation Trunk]
match = ^Installation/Trunk
access = read-write
Hope that helps

Subject: Howto: user-level permissions on Windows?



        I see that Subversion's stand-alone server allows for
repository-level permissions, but is there a way to do user-level
permissions on Windows without running Apache? I want to restrict access
to certain project folders within the same repository.
