On python 3.8 the query for 'between' in a table CANCEL TASK.... #222
Description
Describe the bug
In a table with extra INDEXES, I have a DT_GEN and COUNT (date and int), tested.
The between query as shows on documentation:
On (https://gitlab.com/pineiden/datadbs-rethinkdb/-/blob/master/data_rdb/rdb.py) line 316 and so on
table_manager = self.r.db(dbname).table(table_name)
task_coro = await table_manager.between(
lower, upper, **filter_opt).order_by(order_by).run(
self.session, **options)
result = await task_coro
Task was destroyed but it is pending!
task: <Task pending name='Task-4' coro=<ConnectionInstance._reader() running at /home/david/.virtualenvs/datawork/lib/python3.8/site-packages/rethinkdb-2.4.7-py3.8.egg/rethinkdb/asyncio_net/net_asyncio.py:313> wait_for=<Future pending cb=[<TaskWakeupMethWrapper object at 0x7f7d5a713df0>()]>>
To Reproduce
Mount Rethinkdb 2.4.1
Install Python 3.8
Create a virtualenv
To install dependences and then install from repo:
pip install data-rdb
pip uninstall data-rdbNow clone from:
https://gitlab.com/pineiden/datadbs-rethinkdb
and
python setup.py develop
On folder tests
run
python load_data.py
And
python read_data.py
Those scripts load with dummy data on a table and read that on real time.
Expected behavior
Get the data from the table

Additional context
Add any other context about the problem here.
Well, the core of the query (only with the Rethinkdb module) and Python 3.6.9:
from pytz import timezone
from datetime import datetime, timedelta
import asyncio
from rethinkdb import r as rdb
host = 'localhost'
port = 28015
loop = asyncio.get_event_loop()
rdb.set_loop_type('asyncio')
conn = loop.run_until_complete(rdb.connect(db='test', host=host, port=port))
first = datetime.now() - timedelta(seconds=200)
tz = timezone("America/Santiago")
firsttz = tz.localize(first)
firstrdb = rdb.iso8601(firsttz.isoformat())
post = datetime.now()
posttz = tz.localize(post)
postrdb = rdb.iso8601(posttz.isoformat())
table = "STATION"
filter_opt = {'left_bound': 'open', 'index': "DT_GEN"}
print(f"Desde {firstrdb}, hasta {postrdb}")
query = rdb.db("test").table(table).between(firstrdb, postrdb,
**filter_opt).run(conn)
result = loop.run_until_complete(query)
print(result)
