Re: [ZODB-Dev] Can I use RelStorage with ZODB3.9.0

Now I want to use RelStorage, can I use RelStorage with ZODB3.9.0? Yes and no. I've tested it and it works, but you still need a patched version of ZODB. I haven't posted a patched version of ZODB 3.9 because I expect ZODB 3.9 to eventually include the patch or some variation of it. It would be easy for me to post a patched version of ZODB 3.9.0a12, though. Should I?

Re: [ZODB-Dev] Can I use RelStorage with ZODB3.9.0
Sorry, my mistook, I referred to Zope2.11.2-final. It works ok with Plone3.1.7. best regards eastxing 2009/3/6 Wichert Akkerman wich...@wiggy.net On 3/6/09 6:27 AM, eastxing wrote: Hi all, About one month ago, I asked a question about 'ZODB pack' and got suggestions to update to new ZODB version.

Zope 2.11.2 is indeed not officially supported for Plone 3.x but we have nightly test runs passing for months now. So there's a good chance it'll work. If you want to use RelStorage I suggest using ZODB 3.8 with the appropriate patches. This combination is used in production by a number of people and has been tested. ZODB 3.9 introduces a number of API incompatible changes and will not work with Zope 2.11 in general. I had to change the Zope 2 code for 2.12 in quite a number of places to make it work with ZODB 3.9. I'd be surprised if you get this combination working in a reliable way. Hanno Yes, I backport some codes from Zope2.12 to make Plone3.1.7 work with ZODB3.9.0a12. I really want to use ZODB3.9 cause zc.async1.5.1 needs it. I'll continue test it to ensure all works ok. Now I am so exciting to prepare convert my large site to use RelStorage, hope there is a big performance improvement ahead.

Re: [ZODB-Dev] How to turn off 'GC' when packing on ZODB3.6.2
hi, Laurence Thanks for your reply. But the export/import mechanism is not suit for my situation. My site is now a very complicated system and 'huge'. Zope's export/import mechanism is fragile, I never export a so large site successfully. Now maybe I have three choices: 1. Understand all codes in fspack.py and implement the 'turn off gc when packing' function on ZODB3.6.2; 2. Update my ZODB version from 3.6.2 to 3.8 or later to try use 'zc.FileStorage' ; 3. Convert my site to use 'RelStorage', and use its 'turn off gc' option to pack my site. Yesterday I tried choice 1, but I am not familiar with 'FileStorage' format and can not implement the function myself in a short time( I have done 'Plone' development for years, but I am not so familiar with the underlayer knowledge about 'Zope' ). For choice 2, I have one question: Is high verstion ZODB(3.8 or later) compatable with low version ZODB(3.6.2)? I googled but not find those compatability information. For choice 3, 'RelStorage' provide a 'ZODBConverter', but I do not to know if it can used with ZODB3.6.2?

As an alternative to backporting the changes to pack, you could try doing a zexp export of the site, and then reimport the zexp into a blank Data.fs.
