Bumps peewee from 3.14.10 to 4.0.2.

Release notes

Sourced from peewee's releases.

4.0.2

• Remove all Python 2.x compatibility code.
• Add streaming result cursors to pwasyncio module via db.iterate(query).
• Better serialization and deserialization of datetimes and binary data in the DataSet module. Previously binary data was encoded as base64, going forward hex is the new default. For base64 specify base64_bytes=True.
• Improvements to Postgres BinaryJSONField, support atomic removal of sub-elements, as well as alternate helper for extracting sub-elements and querying array length.
• Pydantic integration

4.0.1

• Ensure gr_context is set on greenlet in greenlet_spawn so that contextvars will be operable in sync handlers.
• Removed SqliteExtDatabase (it basically served no purpose in 4.0). Use SqliteDatabase instead.
• Moved driver and extension-specific pooled implementations into the corresponding extension module rather than putting all into playhouse.pool.
• Restore custom dumps option for postgres JSON fields.
• Major docs rewrite / reorganization.

View commits

4.0.0

• Adds preliminary support for asyncio via a new playhouse extension. See the documentation for details.
• PostgresqlDatabase can use psycopg (psycopg3) if it is installed. If both psycopg2 and psycopg3 are installed, Peewee will prefer psycopg2, but this can be controlled by specifying prefer_psycopg3=True in the constructor. Same applies to PostgresqlExtDatabase.
• Psycopg3Database class has been moved to playhouse.postgres_ext and is now just a thin wrapper around PostgresqlExtDatabase.
• Postgres JSON operations no longer dump and try to do minimal casts, instead relying on the driver-provided Json() wrapper(s).
• Adds new ISODateTimeField for Sqlite that encodes datetimes in ISO format (more friendly when db is shared with other tools), and also properly reads back UTC offset info.
• Remove playhouse.sqlite_ext.ClosureTable implementation.
• Add a Model.dirty_field_names attribute that is safe for membership testing, since testing x in dirty_fields returns True if one or more field exists due to operator overloads returning a truthy Expression object. Refs #3028.
• Removal of Cython _sqlite_ext extension. The C implementations of the FTS rank functions are moved to sqlite_udf. Most of the remaining functionality is moved to playhouse.cysqlite_ext which supports it natively.

Migrating CSqliteExtDatabase usage:

You can either use sqlite_ext.SqliteExtDatabase or try the new cysqlite_ext.CySqliteDatabase if you want all the old functionality and are willing to try a new driver.

3.19.0

• Move to new build system using pyproject and github actions.
• No longer build and ship the Sqlite C extensions by default. Users who prefer to use those can install via the sdist pip install peewee --no-binary :all:.

Rationale about the Sqlite C extensions -- I've started shipping pysqlite3 as a statically-linked, self-contained binary wheel. This means that when using Peewee with the statically-linked pysqlite3, you can end up in a funny situation where the peewee Sqlite extensions are linked against the system libsqlite3, and the pysqlite driver has it's own Sqlite embedded, which does not work.

If you are using the system/standard-lib sqlite3 module then the extension works properly, because everything is talking to the same libsqlite3.
