One of the first things I did when I used Subversion was to tackle this very issue. Most version control systems allow users to create tags and lock them to prevent their accidental changing. Since Subversion doesn't have real tags, it was missing what I considered a vital feature. I wrote what I called a "kitchen sink" hook. It does (to me) several vital tasks. 1). It allows you to define groups, so you can set permission by group instead of individual. 2). It allows you to set files as "read-write", "read-only", and "add-only". That last permission was specifically for tags. If a directory like "tags" is set to "add-only", users can create tags by an "svn copy", but they're not allowed to modify a tag once created. My hook also has a few other functions too: 3). It allows you to force files to have certain attributes and you can optionally specify the values of these attributes. For example, you might want all files that end in "*.ksh" or "*.sh" to have the attribute "svn:eol-style" set to "LF". 4). The script can ban certain file names. For example, I don't like it when *.java files have spaces in them. I can set the hook up to prohibit new "*.java" files from having spaces in the name. And, finally, it can also verify revision properties. Pre-1.5, it can only verify svn:log (which is the commit message). Recent versions of Subversion can verify other revision attributes on commit too. My script is written in Object Oriented Perl. (There's an older version that's much more of a hack, but I rewrote the hook from scratch from scratch to make it more readable and more robust.) It doesn't require anything but the standard Perl modules (the older one required the installation of an optional module which is difficult to do at some sites). You can download it from here: http://db.tt/jnPdsRV. A sample control file is here: http://db.tt/IUarZ0J. There is a new standard pre-commit access control hook written in Python that is available directly from Subversion. I believe it also allows you to specify that your tags directory is "add-only". You may want to look at that. -- David Weintraub qazw...@gmail.com
