svn dump format

[Baruch Burstein <bm...@gmail.com>]

Hi all,

Are the node records in a single revision in a svn dump file
guaranteed/required to be in a sorted lexicographical order? If not, is
that at least the case when using the official dump tools
(svnadmin/svnrdump)?

Please CC me on replys

Thanks,
Baruch

The hash ordering of nodes in dump files was considered a bug:

http://subversion.tigris.org/issues/show_bug.cgi?id=4134

and is fixed in recent versions.

As far as I can see we do not document the order in:

http://svn.apache.org/repos/asf/subversion/trunk/notes/dump-load-format.txt

Not guaranteed or required. The most informative results on this come up with the "apr hash order" keywords in mailing list and CHANGES.

Well there is only official source, and it depends on the apr hash order. I believe that current releases do sort to circumvent the hash order unpredictability. Dumps and revision files.
