Please forgive me if this e-mail is long winded. I do not know if there is
a separate 'user support' mailing list, so hopefully posting it to the dev
mailing list is appropriate. Here goes:
I have been trying to understand the permissions for Subversion. I can't
seem to understand if and why SVN is switching permission bits on me, or if
I'm doing something incorrect with my initial 'svnadmin create' set up to
create the problem in the first place.
I have read the Subversion book at http://svnbook.reb-bean.com/ but it
fails to mention the circumstances under which one creates a repository
(under root, under the svn user, or a possible unix user account which will
have repository committer access).
I am running Subversion 0.25 dev build with debugging turned on; FreeBSD
5.1 with Apache2 2.0.47 (FreeBSD port). Subversion was built with the
following command line:
/usr/local/subversion/bin/svn up ; make distclean ; sh ./autogen.sh ;
./configure --prefix=/usr/local/subversion --enable-maintainer-mode
--with-apr=/usr/local/lib/apache2/apr-config
--with-apr-util=/usr/local/lib/apache2/apu-config --with-neon=/usr/local
--with-apxs=/usr/local/sbin/apxs ; make
I am the only one using this Subversion installation; it is my personal
development sandbox.
I attempted to browse my repository through a web browser this morning and
received the following message back:
Berkeley DB error while checkpointing after Berkeley DB transaction for
filesystem /usr/local/svn/repos/doublespeak/db: DB_RUNRECOVERY: Fatal error,
run database recovery
So I ran /usr/local/subversion/bin/svnadmin recover
/usr/local/svn/repos/doublespeak
It ran without any problems. When I attempted to browse the repository
through the web browser again, I received a permission denied error. I had
done nothing except run the recover facility, so I assumed that it reset the
permission bits on my repository's physical filesystem directory. This is
what the listing looked like:

As soon as I ran 'chmod 644 *' and reloaded by web browser, everything
worked 'as it should' as before.
Now as I understand it, the svn group (of which the Apache2 'www' user is a
member) did not have write access to a few files; when I granted the svn
group write access to the rest of it, it operated as before.
Would someone kindly explain to me what svnadmin does to reassign
permissions, or what I should have done when I initially created the
repository (should I have run svnadmin create as a certain user, certain
group, in a certain directory?) so as to prevent this conflict?
Thanks,
Wesley
