Development information

#######################
6+
7+
8+
The test suite demonstrates the use of the "relaxed" variants of SQLAlchemy's
9+
builtin PostgreSQL support by connecting to databases which are protocol
10+
compatible with PostgreSQL.
11+
12+
Currently, `CrateDB`_ is used. The easiest way to provide an instance to the
13+
test suite, is::
14+
15+
docker run --rm -it --publish=4200:4200 --publish=5432:5432 crate/crate:nightly
16+
17+
18+
For installing the package inside a development sandbox (virtualenv), run::
19+
20+
git clone https://github.com/daq-tools/sqlalchemy-postgresql-relaxed
21+
cd sqlalchemy-postgresql-relaxed
22+
python3 -m venv .venv
23+
source .venv/bin/activate
24+
pip install --editable=.[develop,test]
25+
26+
To run all validation steps (linter, software tests), invoke::
27+
28+
poe check
29+
30+
31+
32+
.. _CrateDB: https://github.com/crate/crate

##########################################
26+
Relaxed PostgreSQL dialects for SQLAlchemy
27+
##########################################
28+
29+
30+
*****
31+
About
32+
*****
33+
34+
The vanilla dialects for connecting to PostgreSQL with SQLAlchemy will employ
35+
a few behaviors that strictly expect a PostgreSQL server on the other end.
36+
However, some operations may croak on databases which only offer
37+
wire-compatibility with PostgreSQL.
38+
39+
The dialects provided by ``sqlalchemy-postgresql-relaxed`` are building upon
40+
the vanilla SQLAlchemy dialects, but will disable a few PostgreSQL specifics.
41+
42+
- ``postgresql+psycopg``: Accept non-conforming server version responses.
43+
- ``postgresql+psycopg``: Don't issue ``SHOW STANDARD_CONFORMING_STRINGS`` inquiry.
44+
- ``postgresql+asyncpg``: Don't strictly expect JSON and JSONB codecs.
45+
46+
47+
*****
48+
Usage
49+
*****
50+
51+
The corresponding dialect identifiers are:
52+
53+
- ``postgresql+psycopg_relaxed``
54+
- ``postgresql+asyncpg_relaxed``
55+
56+
They can be used within SQLAlchemy database URL identifiers as usual.
57+
58+
.. code-block:: python
59+
60+
# psycopg synchronous
61+
create_engine(
62+
url="postgresql+psycopg_relaxed://crate@localhost/acme",
63+
isolation_level="AUTOCOMMIT",
64+
use_native_hstore=False)
65+
66+
# psycopg asynchronous
67+

68+

69+

70+

Development
102+
===========
103+
104+
In order to setup a development environment on your workstation, please head over
105+
to the `development sandbox`_ documentation. When you see the software tests succeed,
106+
you should be ready to start hacking.
