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

Never tried it on Etch yet... I am still running Sarge.

Not sure if 1.4.2 will do... I am running 1.4.3 and I remember something
not working in 1.4.2 altho I think it was the verification process
(pushmi verify). You may have to backport 1.4.3 (should be easy tho...
Tell me if you need help).

Here is a list of packages my pushmi package depends on. You probably
don't need the ones related to Apache.

Install these and see if it helps.

Depends: libapp-cli-perl, liblocale-maketext-simple-perl,
libsvn-core-perl, libsvn-perl, libsvn-simple-perl,
libdata-hierarchy-perl, libclass-data-inheritable-perl,
libclass-autouse-perl, libperlio-eol-perl, libterm-readkey-perl,
libcache-memcached-perl, memcached, libsys-syscall-perl,
libdanga-socket-perl, python-subversion, libuniversal-require-perl,
libyaml-syck-perl, librunapp-perl, libsvn-mirror-perl,
libpath-class-perl, libsvn-mirror-perl, libclass-accessor-perl,
libperlio-via-symlink-perl, libperlio-via-dynamic-perl,
libapache2-mod-perl2,libstring-crc32-perl, liblog-log4perl-perl,
liblog-dispatch-perl, libversion-perl, libpod-simple-perl,
libapache2-svn, libalgorithm-diff-perl, libipc-run3-perl, svk



If it still fails, the author of pushmi will be back shortly. You should
have an answer pretty quickly. 

Im interested in knowing what kind of requirements you have for this
software ? What will you use it for ? :-)

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!
