SQLite abilities to alter tables are very limited (please read

E. g. one can't drop a column or a constraint in SQLite. The
workaround for this is to recreate the original table omitting
the corresponding constraint (or column).
sqlalchemy-migrate library has recreate_table() method that
implements this workaround, but it does it wrong:
- information about unique constraints of a table
is not retrieved. So if you have a table with one
unique constraint and a migration adding another one
you will end up with a table that has only the
latter unique constraint, and the former will be lost
- dropping of unique constraints is not supported at all
The proper way to fix this is to provide a pull-request to
sqlalchemy-migrate, but the project seems to be dead. So we
can go on with monkey-patching of the lib at least for now.

session.set_defaults(
sql_connection="sqlite:///var/lib/gceapi/sqlite.db",
sqlite_db="/var/lib/gceapi/sqlite.db")
Recommended ways to use sessions within this framework:
* Don't use them explicitly; this is like running with AUTOCOMMIT=1.
model_query() will implicitly use a session when called without one
supplied. This is the ideal situation because it will allow queries
to be automatically retried if the database connection is interrupted.
Note: Automatic retry will be enabled in a future patch.
It is generally fine to issue several queries in a row like this. Even though
they may be run in separate transactions and/or separate sessions, each one
will see the data from the prior calls. If needed, undo- or rollback-like
functionality should be handled at a logical level. For an example, look at
the code around quotas and reservation_rollback().
Examples::
def get_foo(context, foo):
return (model_query(context, models.Foo).
filter_by(foo=foo).
first())
def update_foo(context, id, newfoo):
(model_query(context, models.Foo).
filter_by(id=id).
update({'foo': newfoo}))
def create_foo(context, values):
foo_ref = models.Foo()
foo_ref.update(values)
foo_ref.save()
return foo_ref
* Within the scope of a single method, keeping all the reads and writes within
the context managed by a single session. In this way, the session's __exit__
handler will take care of calling flush() and commit() for you.
If using this approach, you should not explicitly call flush() or commit().
Any error within the context of the session will cause the session to emit
a ROLLBACK. Database Errors like IntegrityError will be raised in
session's __exit__ handler, and any try/except within the context managed
by session will not be triggered. And catching other non-database errors in
the session will not trigger the ROLLBACK, so exception handlers should
always be outside the session, unless the developer wants to do a partial
commit on purpose. If the connection is dropped before this is possible,
the database will implicitly roll back the transaction.
Note: statements in the session scope will not be automatically retried.
If you create models within the session, they need to be added, but you
do not need to call model.save()
::
def create_many_foo(context, foos):
session = get_session()
with session.begin():
for foo in foos:
foo_ref = models.Foo()
foo_ref.update(foo)
session.add(foo_ref)
def update_bar(context, foo_id, newbar):
session = get_session()
with session.begin():
foo_ref = (model_query(context, models.Foo, session).
filter_by(id=foo_id).
first())
(model_query(context, models.Bar, session).
filter_by(id=foo_ref['bar_id']).
update({'bar': newbar}))
Note: update_bar is a trivially simple example of using "with session.begin".
Whereas create_many_foo is a good example of when a transaction is needed,
it is always best to use as few queries as possible. The two queries in
update_bar can be better expressed using a single query which avoids
the need for an explicit transaction. It can be expressed like so::
def update_bar(context, foo_id, newbar):
subq = (model_query(context, models.Foo.id).
filter_by(id=foo_id).
limit(1).
subquery())
(model_query(context, models.Bar).
filter_by(id=subq.as_scalar()).
update({'bar': newbar}))
For reference, this emits approximately the following SQL statement::
UPDATE bar SET bar = ${newbar}
WHERE id=(SELECT bar_id FROM foo WHERE id = ${foo_id} LIMIT 1);
Note: create_duplicate_foo is a trivially simple example of catching an
exception while using "with session.begin". Here create two duplicate
instances with same primary key, must catch the exception out of context
managed by a single session:
def create_duplicate_foo(context):
foo1 = models.Foo()
foo2 = models.Foo()
foo1.id = foo2.id = 1
session = get_session()
try:
with session.begin():
session.add(foo1)
session.add(foo2)
except exception.DBDuplicateEntry as e:
handle_error(e)
* Passing an active session between methods. Sessions should only be passed
to private methods. The private method must use a subtransaction; otherwise
SQLAlchemy will throw an error when you call session.begin() on an existing
transaction. Public methods should not accept a session parameter and should
not be involved in sessions within the caller's scope.
Note that this incurs more overhead in SQLAlchemy than the above means
due to nesting transactions, and it is not possible to implicitly retry
failed database operations when using this approach.
This also makes code somewhat more difficult to read and debug, because a
single database transaction spans more than one method. Error handling
becomes less clear in this situation. When this is needed for code clarity,
it should be clearly documented.
::
def myfunc(foo):
session = get_session()
with session.begin():
# do some database things
bar = _private_func(foo, session)
return bar
def _private_func(foo, session=None):
if not session:
session = get_session()
with session.begin(subtransaction=True):
# do some other database things
return bar
There are some things which it is best to avoid:
* Don't keep a transaction open any longer than necessary.
This means that your "with session.begin()" block should be as short
as possible, while still containing all the related calls for that
transaction.
* Avoid "with_lockmode('UPDATE')" when possible.
In MySQL/InnoDB, when a "SELECT ... FOR UPDATE" query does not match
any rows, it will take a gap-lock. This is a form of write-lock on the
"gap" where no rows exist, and prevents any other writes to that space.
This can effectively prevent any INSERT into a table by locking the gap
at the end of the index. Similar problems will occur if the SELECT FOR UPDATE
has an overly broad WHERE clause, or doesn't properly use an index.
One idea proposed at ODS Fall '12 was to use a normal SELECT to test the
number of rows matching a query, and if only one row is returned,
then issue the SELECT FOR UPDATE.
The better long-term solution is to use INSERT .. ON DUPLICATE KEY UPDATE.
However, this can not be done until the "deleted" columns are removed and
proper UNIQUE constraints are added to the tables.
Enabling soft deletes:
* To use/enable soft-deletes, the SoftDeleteMixin must be added
to your model class. For example::
class NovaBase(models.SoftDeleteMixin, models.ModelBase):
pass
Efficient use of soft deletes:
* There are two possible ways to mark a record as deleted::
model.soft_delete() and query.soft_delete().
model.soft_delete() method works with single already fetched entry.
query.soft_delete() makes only one db request for all entries that correspond
to query.
* In almost all cases you should use query.soft_delete(). Some examples::
def soft_delete_bar():
count = model_query(BarModel).find(some_condition).soft_delete()
if count == 0:
raise Exception("0 entries were soft deleted")
def complex_soft_delete_with_synchronization_bar(session=None):
if session is None:
session = get_session()
with session.begin(subtransactions=True):
count = (model_query(BarModel).
find(some_condition).
soft_delete(synchronize_session=True))
# Here synchronize_session is required, because we
# don't know what is going on in outer session.
if count == 0:
raise Exception("0 entries were soft deleted")
* There is only one situation where model.soft_delete() is appropriate: when
you fetch a single record, work with it, and mark it as deleted in the same
transaction.
::
def soft_delete_bar_model():
session = get_session()
with session.begin():
bar_ref = model_query(BarModel).find(some_condition).first()
# Work with bar_ref
bar_ref.soft_delete(session=session)
However, if you need to work with all entries that correspond to query and
then soft delete them you should use query.soft_delete() method::
def soft_delete_multi_models():
session = get_session()
with session.begin():
query = (model_query(BarModel, session=session).
find(some_condition))
model_refs = query.all()
# Work with model_refs
query.soft_delete(synchronize_session=False)
# synchronize_session=False should be set if there is no outer
# session and these entries are not used after this.
When working with many rows, it is very important to use query.soft_delete,
which issues a single query. Using model.soft_delete(), as in the following
example, is very inefficient.
::
for bar_ref in bar_refs:
bar_ref.soft_delete(session=session)
# This will produce count(bar_refs) db requests.

So we must return values that follow the passed marker in the order.
With a single-valued sort_key, this would be easy: sort_key > X.
With a compound-values sort_key, (k1, k2, k3) we must do this to repeat
the lexicographical ordering:

2) Wrappers around loads() and dumps(). The dumps() wrapper will
automatically use to_primitive() for you if needed.

"""Openstack logging handler.
This module adds to logging functionality by adding the option to specify
a context object when calling the various log methods. If the context object
is not specified, default formatting is used. Additionally, an instance uuid
may be passed as part of the log message, which is intended to make it easier
for admins to find messages related to a specific instance.
It also allows setting of formatting information through conf.
