[Zope-Checkins] CVS: Zope2 - FileStorage.py:1.37.12.8

[Jim Fulton]

Update of /cvs-repository/Zope2/lib/python/ZODB
In directory korak.digicool.com:/tmp/cvs-serv10625

Modified Files:
      Tag: Zope-2_2-branch
	FileStorage.py 
Log Message:
- Removed optimization in commitVersion that caused versions to be
  committed incorrectly when there were multiple stores for an object
  in a transaction.

- Changed pack to (re)open the database in read-only mode. This
  enables packing a database off-line via a symlink.

- Added read_only option to read_index so that it doesn't try to
  truncate a database opened read_only.  This could happen when
  opening a database that is open and being actively written by
  another process.

- Log an error rather than panic when we find a bad previous record
  pointer.
