GINO 1.0

Migrating to GINO 1.0

GINO 1.0 moved the built-in Web framework extensions into separate PyPI packages. If you're using one of them, you should install GINO 1.0 with extras:

Extension Module	Installation in GINO 1.0
`gino.ext.starlette`	`pip install gino[starlette]`
`gino.ext.aiohttp`	`pip install gino[aiohttp]`
`gino.ext.sanic`	`pip install gino[sanic]`
`gino.ext.tornado`	`pip install gino[tornado]`
`gino.ext.quart`	`pip install gino[quart]`

The new extension packages are backward-compatible, so there's no need to update the import statements. For example, this will still work in GINO 1.0 if you installed gino[starlette]:

from gino.ext.starlette import Gino

GINO 1.0 switched to Poetry for package and dependency management and started to use the src layout. This shouldn't cause any problem using GINO as a dependency, but it does introduce some changes to the GINO development process:

Source files are now located under src directory.
The src dist on PyPI does not include tests, docs and some other files due to a limitation of Poetry.

1.0.1 (2020-06-08)

Fixed dependency version range (SQLAlchemy >=1.2.16, <1.4)
Updated docs (Including contribution by Galden in #660, and Iuliia Volkova in #672)
Multiple JSON property fixes (#661 #662 #695)
Fixed extension typing issue (#673 #674)
Fixed model override behavior (#694)
Fixed multiple JSON profiles issue (Contributed by Roman Averchenkov in #693 #696)

1.0.0 (2020-04-26)

Switched to Poetry for package and dependency management.
[Breaking] Moved built-in extension modules to separate PyPI packages.
Switched to src layout.
Switched to black code style.
Better documentation.
[Breaking] none_as_none() is now always enabled.
Added representation method for engine.
Protected the URL instance fed to set_bind() from manipulation.
Replaced some assert with AssertionError (#258 #655)

GINO 0.8

This is also version 1.0 release candidate.

Migrating to GINO 0.8

1. contextvars

We introduced aiocontextvars 0.2.0 which is revamped to be compatible with PEP-567 without manual interference by a few simple implicit patches. To upgrade to GINO 0.8, please remove the enable_inherit() or disable_inherit() calls, because they are the default behavior now thus no longer exist. However, you'll need to confirm that the event loop in use is always created after importing gino or aiocontextvars, or the patch won't work correctly.

There is nothing to worry about in Python 3.7.

2. none_as_none

When GINO tries to load a row with all NULL values into an instance, it will now by default return None instead of an instance with all None attributes. To recover the default behavior of 0.7, please specify none_as_none(False) in affected model loader.

This is especially applicable to relationship sub-loaders - if the sub-loader found it all NULL, no instance will be set to parent instance. For example:

child = await Child.load(parent=Parent).query.gino.first()

If child.parent_id is NULL in database, then the child instance won't be called with any setattr(child, 'parent', ...) at all. (If you need child.parent == None in this case, consider setting default value parent = None in child model.)

Please note, it is deprecated to disable none_as_none, and disabling will be removed in GINO 1.0.

GINO 0.6

This is also version 1.0 beta 2.

Migrating to GINO 0.6

1. Task Local

We created a new Python package aiocontextvars from previous local.py. If you made use of the task local features, you should install this package.

Previous gino.enable_task_local() and gino.disable_task_local() are replaced by aiocontextvars.enable_inherit() and aiocontextvars.disable_inherit(). However in GINO 0.5 they controls the whole task local feature switch, while aiocontextvars by default offers task local even without enable_inherit(), which controls whether the local storage should be passed between chained tasks. When enabled, it behaves the same as enabled in 0.5, but you cannot completely turn off the task local feature while aiocontextvars is installed.

There is no gino.get_local() and gino.reset_local() relevant in aiocontextvars. The similar thing is aiocontextvars.ContextVar instance through its get(), set() and delete() methods.

Previous gino.is_local_root() is now not aiocontextvars.Context.current().inherited.

2. Engine

GINO 0.6 hides asyncpg.Pool behind the new SQLAlchemy-alike gino.GinoEngine. Instead of doing this in 0.5:

async with db.create_pool('postgresql://...') as pool:
    # your code here

You should change it to this in 0.6:

async with db.with_bind('postgresql://...') as engine:
    # your code here

This equals to:

engine = await gino.create_engine('postgresql://...')
db.bind = engine
try:
    # your code here
finally:
    db.bind = None
    await engine.close()

Or:

engine = await db.set_bind('postgresql://...')
try:
    # your code here
finally:
    await db.pop_bind().close()

Or even this:

db = await gino.Gino('postgresql://...')
try:
    # your code here
finally:
    await db.pop_bind().close()

Choose whichever suits you the best.

Obviously GinoEngine doesn't provide asyncpg.Pool methods directly any longer, but you can get the underlying asyncpg.Pool object through engine.raw_pool property.

GinoPool.get_current_connection() is now changed to current_connection property on GinoEngine instances to support multiple engines.

GinoPool.execution_option is gone, instead update_execution_options() on GinoEngine instance is available.

GinoPool().metadata is gone, dialect is still available.

GinoPool.release() is removed in GinoEngine and Gino, the release() method on GinoConnection object should be used instead.

These methods exist both in 0.5 GinoPool and 0.6 GinoEngine: close(), acquire(), all(), first(), scalar(), status().

3. GinoConnection

Similarly, GinoConnection in 0.6 is no longer a subclass of asyncpg.Connection, instead it has a asyncpg.Connection instance, accessable through GinoConnection.raw_connection property.

GinoConnection.metadata is deleted in 0.6, while dialect remained.

GinoConnection.execution_options() is changed from a mutable dict in 0.5 to a method returning a copy of current connection with the new options, the same as SQLAlchemy behavior.

GinoConnection.release() is still present, but its default behavior has been changed to permanently release this connection. You should add argument permanent=False to remain its previous behavior.

And all(), first(), scalar(), status(), iterate(), transaction() remained in 0.6.

4. Query API

All five query APIs all(), first(), scalar(), status(), iterate() now accept the same parameters as SQLAlchemy execute(), meaning they accept raw SQL text, or multiple sets of parameters for "executemany". Please note, if the parameters are recognized as "executemany", none of the methods will return anything. Meanwhile, they no longer accept the parameter bind if they did. Just use the API on the GinoEngine or GinoConnection object instead.

5. Transaction

Transaction interface is rewritten. Now in 0.6, a GinoTransaction object is provided consistently from all 3 methods:

async with db.transaction() as tx:
    # within transaction

async with engine.transaction() as tx:
    # within transaction

async with engine.acquire() as conn:
    async with conn.transaction() as tx:
        # within transaction

And different usage with await:

tx = await db.transaction()
try:
    # within transaction
    await tx.commit()
except:
    await tx.rollback()
    raise

The GinoConnection object is available at tx.connection, while underlying transaction object from database driver is available at tx.transaction - for asyncpg it is an asyncpg.transaction.Transaction object.
