Comments on: Subversion Versions http://www.donniepinkston.net/2006-05-15/subversion-versions.html (there are many more like it, but this one is mine) Tue, 06 Jan 2009 06:18:26 +0000 http://wordpress.org/?v=2.5.1 By: donnie http://www.donniepinkston.net/2006-05-15/subversion-versions.html#comment-675 donnie Tue, 20 Jun 2006 17:47:47 +0000 http://www.donniepinkston.net/?p=71#comment-675 I clarified my explanation above, about the default contents of a repository-dump. As Ben points out, YES, you definitely want every version of every file to be represented in the dump, so that you get your history too! My complaint is simply that the dump contains (by default) the full contents of each version of each file, which can definitely get BIG!! This behavior can be changed with the <code>--deltas</code> switch. I clarified my explanation above, about the default contents of a repository-dump.

(Go to the <a href="http://svnbook.red-bean.com/nightly/en/svn.reposadmin.maint.html#svn.reposadmin.maint.migrate" rel="nofollow">Migrating a Repository</a> section, and start reading after the third command-line inset.) It says that full versions of each update is dumped, but that deltas can be turned on if desired. I don't know if this behavior has changed from Subversion 1.2 to 1.3; the 1.2 command-line documentation agrees with the book, and I don't have 1.3 installed so I can't see what it says.

SVN and the CS admins has a long, grueling history. Ask me about it in email later. 2. You rarely need to do a dump and load with svn anymore. Newer clients are backward-compatible with older repositories, and new features fail gracefully against older ones. 3. The dump doesn't actually dump every version, it dumps the *deltas* for each version... at least, where the deltas are smaller than just dumping the whole thing. (Heuristic approach to guess at that, I believe.) You do want the entire version history preserved, right? Hey Donnie,
