Summary: Support selecion session/otk data store. Add redis as data store.
Allow admin to select the backend data store. Compatibility matrix:
main\/ session>| anydbm | sqlite | redis | mysql | postgresql |
anydbm | D | | X | | |
sqlite | X | D | X | | |
mysql | | | | D | |
postgresql | | | | | D |
--------------------------------------------------------------+
D - default if unconfigured, X - compatible choice
DETAILS
roundup/configuration.py:
add config.ini section sessiondb with settings: backend and redis_url.
CHANGES.txt, doc/admin_guide.txt, doc/installation.txt, doc/upgrading.txt:
doc on config of session db and redis. Plus some other fixes:
admin - clarified why we do not drop __words and __testids
table in native-fts conversion. TYpo fix.
upgrading - doc how you can keep using anydbm for session data with
sqlite. Fix dupe sentence in an upgrading config.ini
section.
roundup/backends/back_anydbm.py, roundup/backends/back_sqlite.py:
code to support redis, redis/anydbm backends respectively.
roundup/backends/sessions_redis.py
new storage backend for redis.
roundup/rest.py, roundup/cgi/actions.py, roundup/cgi/templating.py
redis uses a different way of calculating lifetime/timestamp.
Since expiration of an item occurred if its timestamp was more
than 1 week old, code would calculate:
now - 1 week + lifetime.
But this results in faster expiration in redis if used for
lifetime/timestamp.
Convert code to use the lifetime() method in BasicDatabase
that generates the right timestamp for each backend.
test/session_common.py:
added tests for more cases, get without default, getall non-existing
key etc. timestamp test changed to use new self.get_ts which is
overridden in other tests. Test that datatypes survive storage.
test/test_redis_session.py:
test redis session store with sqlite and anydbm primary databases
test/test_anydbm.py, test/test_sqlite.py
add test to make sure the databases are properly set up
sqlite - add test cases where anydbm is used as datastore
anydbm - remove updateTimestamp override add get_ts().
test/test_config.py
tests on redis_url and compatibility on choice of sessiondb backend
.travis.yml:
add redis db and redis-py
