Re: delete/wipe out repositories (from the database)?
Hi KM,
yeah, that's really easy and I did that before myself (deleting the
directories, no prob). But: when I imported the projects from eclipse
lately there was no directory created, I spent a while to find something
named even similar to an expected directory name but could not find
anything.
I asked my provider (I run the svnserve on a managed box) and the answer
was that all repositories are stored in a database - that's why I asked
how I can completely delete the DB without destorying the installation.
Leads me to another question: maybe eclipse/subclipse only created
folders and not real repositories?
Seems the situation is a bit weird or - more likely - I am missing some
information.
Any more ideas?
Thanks,
Henning

I use that plugin, and that option is for create a 'conection' to a
repository that already exits, could be in local, could be in another
machine, and always using svn or svn+ssh (doesn't work with file:///).
That location let you see the projects and their contents, make a
checkout,...

I missunderstood the share project wizard in Eclipse (subclipse plugin),
in step 2 it offers to 'create a new repository location'. Now this
practically only seems to create folders in the exisiting repository, I
will use the command line create syntax to create my repositories in the
future.

I finally found out what's up when I discovered svnlook tree. Now I can
create the 'real' new repositories as described in my other mail.

Wait: what are you expecting? 'import' doesn't create a repository, at least
not as far as SVN is concerned. If Eclipse make something different of it you
would have to ask some Eclipse people or rather those that make the Eclipse
plugin, which is a separate project from subversion.

If you are using svnserve, the repositories also reside on the machine it is
running on. Deleting them remains a simple recursive delete of the path you
gave to 'svnadmin create'. I assume that you didn't create any repository, so
you need to ask your admin - there is no way to obliterate information from a
Subversion repository via svnadmin, and that's good so.
Now, what could also be the case is that you are mistaking the difference
between a working copy and a repository. Read about the difference in the
Subversion book.

Andreas wasn't quite right here. BDB is the default repository type
through the end of the Subversion 1.1.x series. FSFS became available
in 1.1.0 and became the default in 1.2.0. So if you did not specify
otherwise, your repositories that you created with 1.1.3 are BDB.

no, maybe I was wrong when I said BDB. SVN version is 1.1.3 and it fits
for my needs (at the moment), this might change later. I did not create
repositories with BDB manually and so I don't think it's actually in
use, the default was used for the creation.

there are two main reasons, the most important is that I might share
some projects with other freelancers and some not, so rights management
was important to me and at my point of knowledge it was the easiest way
to have seperate confs with own passwd files which means seperate
repositories.
Last night I spent a while with
http://svnbook.red-bean.com/en/1.1/ch05s04.html#svn-ch-5-sect-6.1
and so think the above setup is the best solution for me, might not be
for you or others.

yep, I knew that before. But anyway I don't like the thought of mixing
up revision numbers across all my projects, even from a general
structural point of view I don't like this behaviour; it simply doesn't
seem logic to me. In addition I discussed that with a freelancer friend
and he had the direct opposite experience you had: he started with a
single repository in the beginning and it really gets on his nerves now.
When you combine this with the argument above I guess for me it was the
right way to have multiple repositories, I am not such a poweruser
anyway and will have a little number of files in the repositories; the
projects are almost completely seperate from each other. But mankind
always learns by experience and so I might change my structure later.
Anyway: thanks for sharing your thoughs, it's always good to have an
additional perspective.
Cheers,
Henning

Why do you use Berkeley DB? This can be because your provider installed
a really old Subversion version (<=1.1). For newer versions FSFS will be
the default database format. Your provider probably took Subversion from
the Linux distribution which is very out-dated in many cases.
Or do you have a specific reason why you need to create a BDB
repository?
> which will for me be multiple repositories because I don't like global

But you know that you will never be able to perform operations across
Subversion repositories, e.g. merging, copying, etc.?
When I started using Subversion I also created tons (i.e. <10) distinct
repositories, but finally I set up a new repository structure which
consolidates all repositories into one big repository. Only my private
photo collection resides in its own repository.
When using Subversion you totally have to forget the meaning of a
revision number. Nearly all repository operations increase the number,
and the only information Rn > Rm contains is that Rn is newer than Rm.
Nothing more.
You should never rely on a specific revision number in the long term
view ("R1234 contains the release for customer X."). For releases you
have to copy a revision (in most cases HEAD) to a release or tags
branch.

Ha! Yes, some information was missing: subclipse did not create a real
repository as we would do with svnadmin create /... etc., it really
only created new folders for the projects in the Berkeley DB. To get rid
of my testdata I simply moved that folder and created the root
repository again, problem solved. Missleading was the term root
repository, I got it from the installation mail of my provider - there
is nor root repository, the root repository is just one among other
repositories.
Now that is clear the questions come more to the point of
http://svnbook.red-bean.com/en/1.1/ch05s04.html#svn-ch-5-sect-6.1
which will for me be multiple repositories because I don't like global
revision numbers.
Thanks to all,
Henning
