feat: Add support for SQLAlchemy 1.4 #177

jimfulton · 2021-05-17T20:19:36Z

Thank you for opening a Pull Request! Before submitting your PR, there are a few things you can do to make sure it goes smoothly:

Make sure to open an issue as a bug/issue before writing your code! That way we can discuss the change, evaluate designs, and agree on the general idea
Ensure the tests and linter pass
Code coverage does not decrease (if any source code was changed)
Appropriate docs were updated (if necessary)

Fixes #83 🦕

The source of the dependency bug is in old versions of google-cloud-core that depend on too-old versions of google-api-core.

Some tests are still failing, but we're far enough along that we have the right shape, I think.

@bar

The moral equivalent of "where foo in (@bar)", where bar is an array which actually need to be "where foo in unnest (@bar)".

Doh!

Other fixes: - Handle BIGINT - Fix string leteral formatting (and start type-specific adaptations).

…ures

The SQLAlchemy like convenience functions (e.g. ) escape incorrectly for BigQuery, so re-escape.

We could make that work, if we want to. :)

…nt_digits

…ry keys, etc., that BigQuery doesn't have.

#78

…xpect

The source of the dependency bug is in old versions of google-cloud-core that depend on too-old versions of google-api-core.

So we don't have t mock at the api level.

#78

- Run tests in temporary directory rather than sharing memory connections. Because simpler. :) - Introduce cross-connection state and record queries in it, so tests can make assertions bout generated queries.

…laceholder The BigQuery Python Client supports an extended placeholder syntax that includes type information, as in `%(foo:INT64)s` (named) or `%(:INT64)s` (unnamed). When we know the type, include it in the placeholder.

The numeric tests now tun since we started passing type info from sqla to bigquery. The CTE tests test features that don't exist in bigquery.

Although the test isn't actually testing dialect code. Maybe it should be skipped instead. Also set the profile test pasth to a more reasonable value, although it doesn't seem to be used. <shrug>

Also inlined colspecs code, because there wasn't much and it facilitated separating literal processing into a function.

redundant comment

No. This makes it easy for me to test with 1.3. :) I want to make sure I don't break 1.3 but the compliance tests are too expensive to tun twice, so I just run them manually.

On second thought, let's run the compliance test for both in CI.

When i worked on this change, i was a bit worried about the consequences of users passing "inline" as a named parameter.

AFAIR - it was removed from SQLA right?

I wasn't thinking about users passing inline. :)

Yes, SQLA removed it in 1.4. I want this code to work with earlier versions and since we're only using statement, I'm just passing the later arguments along.

+sqlalchemy==1.3.24


why Is that different than 3.9 constraint on SQLA?

To make sure we run with 1.3 in some of the unit tests.

There are code paths needed for 1.3 that aren't exercised with 1.4. Without this, we wouldn't have the required 100% test coverage (and wouldn't be testing with 1.3).

@alonme Thanks for taking a look!

plamut

Generally looks fine, although I know far too few details about SQLALchemy dialects to give a definite verdict.

The version check is something that would be nice to fix, the rest are just trivial remarks.

pybigquery/sqlalchemy_bigquery.py

pybigquery/_helpers.py

noxfile.py

Also be a little DRYer.
