semidbm 0.4.0

Overview

SemiDBM is an attempt at improving the dumbdbm in the python standard library. It’s a slight improvement in both performance and in durability. It can be used anywhere dumbdbm would be appropriate to use, which is basically when you have no other options available. It uses a similar design to dumbdbm which means that it does inherit some of the same problems as dumbdbm, but it also attempts to fix problems in dumbdbm, which makes it only a semi-dumb dbm :) It supports a “dbm like” interface:

import semidbm
db = semidbm.open('testdb', 'c')
db['foo'] = 'bar'
print db['foo']

db.close()
# Then at a later time:
db = semidbm.open('testdb', 'r')
# prints "bar"
print db['foo']

A design goal of semidbm is to remain a pure python dbm. This makes installation easy and allows semidbm to be used on any platform that supports python.

Improvements

Below are a list of some of the improvements semidbm makes over dumbdbm.

Limitations

• Not thread safe; can’t be accessed by multiple processes.

• The entire index must fit in memory. This essentially means that all of the keys must fit in memory.
