Thanks for your reply. But the export/import mechanism is not suit for my
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
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
For choice 3, 'RelStorage' provide a 'ZODBConverter', but I do not to know
if it can used with ZODB3.6.2?
