[Python-checkins] python/dist/src/Lib/bsddb init.py,1.9,1.10

Sat Sep 27 19:00:25 EDT 2003

Update of /cvsroot/python/python/dist/src/Lib/bsddb
In directory sc8-pr-cvs1:/tmp/cvs-serv11621/bsddb
Modified Files:
	__init__.py 
Log Message:
Use a threadsafe private DBEnv for each bsddb compatibility interface
db that is opened. DB_THREAD and DB_INIT_LOCK allow for multithreaded
access. DB_PRIVATE prevents the DBEnv from using the filesystem
(making it only usable by this process; and in this implementation
using one DBEnv per bsddb database)
