[Pushmi-users] svm locking issue, potentially related revision number problem

[Aaron Dulles-Coelho]

Sure...

All machines are Debian Etch (4.0)
All machines run Perl 5.8.8

The systems share passwd and shadow info from a central cfengine
service, and they accept passwordless ssh between them. I say this
because that's how svn+ssh:// works on this set-up... it's a
passwordless ssh that starts an svnserve process started on the
server.

I'll note the modules that are specified as required by Pushmi's Makefile.PL

Pushmi is 0.994.0

version.pm version 0.7203

SVN::Core is 1.4.2. I think. Only one copy of Core.pm exists on the
system, and it's provided by a Debian package libsvn-perl. The file
itself has no version info, but the libsvn-perl deb package is
1.4.2dfsg1-2

SVK 2.0.1

App::CLI 0.07

Cache::Memcached 1.34

YAML::Syck 0.71

Log::Log4perl 1.07

Here's a question I've been researching but can't find any answers to:
what's the specification of SVN::Repos::replay2() ? I can't find
source for this anywhere!
