Cleaning up a ZODB storage from 'versions'

[Andreas Jung-5]

Hi there,

we are in the situation that we are running Zope 2.11 with heavily
patched ZODB 3.8 with this extension:

https://blueprints.launchpad.net/zodb/+spec/dm-pack-optimization

While packing a storage we figured out that this extension is
not compatible with the ZODB "versions" feature - means: we can
not pack a particular storage.

Is there a way for cleaning up a storage and removing the related
versions in some way?

Andreas

Yes. Use the ZODB 3.8 strip_versions script.

I used this buildout to get this script available in isolation:

[buildout]
parts =
   fixer
versions = versions

[versions]
ZODB3 = 3.8.3b1

[fixer]
recipe = zc.recipe.egg
eggs = ZODB3

...it doesn't need an instance home or any such, as it just copies a
source .fs file (which can be in use) to a new .fs fiel but minus the
versions.

cheers,

Chris

PS: Andreas, I could have taken your usual approach and just shouted at
you to use Google since Jim already helped me through this about a month
ago ;-)

The usual approach is: looking at the sources..but this script does not
seem to be part of the standard Zope2 distro :-)
