Describe the bug
In version 1.9.0, this project has added support for Redis-7.
But when I try to use the new expire command feature. It raises the following error:

>>> import fakeredis
>>> r = fakeredis.FakeRedis()
>>> r.expire("KEY", 10, nx=True)

redis.exceptions.ResponseError: wrong number of arguments for 'expire' command

To Reproduce
Steps to reproduce the behavior:

1. Install fakeredis 1.9.0
2. exec python
3. exec following instructions:

>>> import fakeredis
>>> r = fakeredis.FakeRedis()
>>> r.expire("KEY", 10, nx=True)

4. See error

redis.exceptions.ResponseError: wrong number of arguments for 'expire' command

Expected behavior
A clear and concise description of what you expected to happen.
Set expiry (10) only when the key ("KEY") has no expiry

Describe the bug
Using fakeredis 1.7.6 on unit tests automated by tox gives a ModuleNotFoundError: No module named 'sortedcontainers'. This error does not happen on 1.7.5. Maybe sortedcontainers should be added as a dependency?

To Reproduce
Steps to reproduce the behavior:

1. Create a unit test that uses fakeredis 1.7.6
2. Run unit test on a clean virtualenv created by tox
3. See error

Expected behavior
sortedcontainers should be installed together with fakeredis as a dependency

zrangebyscore is deprecated in redis and replace by zrange with a byscore=True argument. This isn't handled in fakeredis, and I needed to change _zrange in _fakesocket to the following to handle this case:

    def _zrange(self, key, start, stop, reverse, *args):
        zset = key.value
        withscores = False
        byscore = False
        for arg in args:
            if casematch(arg, b'withscores'):
                withscores = True
            elif casematch(arg, b'byscore'):
                byscore = True
            else:
                raise SimpleError(msgs.SYNTAX_ERROR_MSG)
        if byscore:
            items = zset.irange_score(ScoreTest(start).lower_bound, ScoreTest(stop).upper_bound, reverse=reverse)
        else:
            start, stop = self._fix_range(start, stop, len(zset))
            if reverse:
                start, stop = len(zset) - stop, len(zset) - start
            items = zset.islice_score(start, stop, reverse)

        items = self._apply_withscores(items, withscores)
        return items

Describe the bug
When the REDIS_URL environment variable is set and it contains username and password this exception is raised:

To Reproduce

1. set REDIS_URL environment variable with a such value which includes username and password e.g. redis://user:password@host:11234
2. queue any action/function, e.g. queue a function decorated with @rq.job()
3. See error mentioned above

Expected behavior
The function should be run without any failure as it works with using REDIS_URL connection string without username or password.

Desktop:

Describe the bug

In 1.8.1, if you try to create an instance of FakeRedis and pass in the the host & port args positionally, rather than by keyword - which is a perfectly valid and functional way of instantiating Redis - it will fail:

• FakeRedisMixin.__init__() sets any keyword argument which you don't give it to the default value extracted from the signature of Redis.__init__() in **kwds
• However, it doesn't check if any of those arguments have been passed positionally in *args
• Thus, when it calls the Redis constructor as super().__init__(*args, **kwds), the host argument is set twice - once positionally and once by keyword - which is not legal in Python

To Reproduce

This is the code under test:

connection: redis.Redis = redis.Redis(redis_host, redis_port)

Patch it to this:

connection: redis.Redis = fakeredis.FakeRedis(redis_host, redis_port)

Expected behavior

FakeRedis should be a drop-in replacement for Redis

Actual behaviour

/usr/local/lib/python3.7/site-packages/fakeredis/_server.py:145: TypeError: __init__() got multiple values for argument 'host'

Desktop (please complete the following information):

• OS: Alpine Linux v3.13
• Python version: 3.7.10
• redis-py version: 3.2.1
• fakeredis version: 1.8.1

I was using version 1.7.1 and this code worked

import redis
import arrow
import fakeredis

from datetime import date


def test_state(monkeypatch):
    monkeypatch.setattr(redis,'Redis',fakeredis.FakeRedis )

    from ..src.status import SystemState
    state = SystemState()

    print(state.serial)
    assert state.version == '2.0'
    assert state.timezone == 'America/New_York'
    state.lights = 'off'
    value, when = state.lights
    assert value == 'off'
 

However in 1.8 I get a connection pool error

I cannot find the most recent fakeredis version 1.8.1 in pypi. Is there anything holding the release back?

Is your feature request related to a problem? Please describe.
Currently, supported commands are triggered based on _fakeredis_sig (which @command decorator creates).

Describe the solution you'd like
A dictionary of command name to singature, to ensure module commands are supported easily.

See discussion in this commit.

• Test should be added for python3.7 on github action
• Should be added to tox.ini
• Handle importlib.metadata error

Is your feature request related to a problem? Please describe.
At the moment, there is a lot of duplicate code on the test files (for skipping tests, etc.)

Describe the solution you'd like
Move all common methods (e.g., lupa_required_for_test, redis_below_v3) to conftest.py and use them appropriately.

Is your feature request related to a problem? Please describe.
Aioredis is now in redis-py 4.2.0rc1+ as described here

Describe the solution you'd like
Default should be not requiring aioredis.

Describe the bug
Am I right that python-six dependency could be removed?

See discussion on #13. lupa and aioredis should be optional dependencies.

• Make lupa and aioredis optional in pyproject.toml
• Create a test scheme where lupa is not installed.

I see that in #12 you migrated to poetry, where before you did have lupa and aioredis as optional in your setup.cfg:

[options.extras_require]
lua =
    lupa
aioredis =
    aioredis

but it doesn't seem to be the case in the pyproject.toml today with Poetry, unless there is some different way that I'm not aware of to mark them as optional. As per the poetry documentation that's how extras are 'expected' to be defined at least - if there's a different way it's specified in this project then I'd love to learn about that.

Separate all commands to mixin classes:

• string_mixin.py
• server_mixin.py
• bitmap_mixin.py
• list_mixin.py
• sortedset_mixin.py
• generic_mixin.py
• transactions_mixin.py
• connection_mixin.py

Describe the bug
pottery.RedisDict requires host as part of connection_pool.connection_kwargs.
https://github.com/brainix/pottery/blob/c7be6f1f25c5404a460b676cc60d4e6a931f8ee7/pottery/base.py#L90

To Reproduce
Create a pottery.RedisDict using an instance of fakeredis.

Solution
The solution already tested is to add host to this list

I could make the change and create the PR if that helps in any way

Thanks!

Is your feature request related to a problem? Please describe.
Enable support for redis 4.4 - currently in RC status.

Describe the bug
Current version of fakeredis constrains redis version to be <4.4, however a security vulnerability was identified and fixed in versions 6.2.7 and 7.0.0.

To Reproduce
N/A

Expected behavior
fakeredis should upgrade its dependency on redis to include vulnerability fix.

Describe the bug
Signature in fakeredis dont match normal redis client for set commands, srem in particular.

from fakeredis import FakeRedis
r = FakeRedis()
r.srem(name='somekey', values='one')

This crash with values does not exist, and I check the signature and members is there instead for fakeredis that is.

Workaround is to use r.srem('somekey', 'one') which I really dont like.

To Reproduce
Steps to reproduce the behavior:
just run the codesample above

In fakeredis the values field is called members, this needs to be updated.

Expected behavior
I expect the codesample above to work.

Implement support for command BITFIELD (documentation). Perform arbitrary bitfield integer operations on strings

Describe the bug
fakeredis does not work out-of-the-box with redis-py versions earlier than 4.1.0 since 62133d2 as importlib-metadata was not a redis-py dependency before this point.

redis-py introduced importlib-metadata in 4.1.0. You can see this here redis/redis-py@v4.0.2...v4.1.0 (click "Files changes" and scroll to setup.py)

To Reproduce
Using Python 3.7

pip install redis==3.5.3
pip install fakeredis
python -c "import fakeredis"

Expected behavior
fakeredis should require importlib-metadata itself as it is required as a direct dependency of the fakeredis code.

Describe the bug
When using Django cache with a Redis backend, the get() call returns an int if the value stored is an integer. FakeRedis returns a byte string for the same get() call.

Expected behavior
If the value stored is an integer (as can be confirmed with .incr()) the returned value should be an int rather than a byte string.

Implement support for command (documentation). Clears all values from an array or an object and sets numeric values to

@cunla First, huge thanks for maintaining the repo to begin with.

Second, can I ask for a little guidance on the "correct" way to add an implementation for a currently unimplemented command? The application whose test suite we're using fakeredis-py in uses zmscore in a few critical places, so I've had to implement a functional standin for it and sort of monkey-patch it into fakeredis-py as part of the test setup. It's not a huge deal at all, but it seems silly to not contribute the implementation to the fakeredis-py repo.

I did take a look at the repo itself, but very quickly got confused as to where exactly a given COMMAND is "fulfilled" by a given callable / function. I'd be more than happy to make a PR if you'd give me the quick and dirty how-to on adding a new command.

For reference, this is the implementation of zmscore I worked out:

from __functools__ import annotations
from typing import Any, Iterable
import fakeredis


def zmscore(self: fakeredis.FakeRedis, key: str | bytes, members: Iterable[Any]) -> tuple[float, ...]:
    """A functional stand-in for Redis's `zmscore` function."""
    pipe = self.pipeline()

    for member in members:
        member = member if isinstance(member, bytes) else str(member).encode()
        pipe.zscore(name=str(key), key=member)

    return tuple(pipe.execute())

Is your feature request related to a problem? Please describe.
Implement JSON.MGET

Currently handling of optional redis command arguments is implemented on each command separately.
(examples: sort, restore, _zrangebyscore, zadd, set_)

The logic should be extracted to a common method handling these:

def _handle_optional_args(args:list[bytes], allowed_args:set[bytes]) -> set[bytes], list[bytes]:
"""Returning a set of allowed arguments in args and a list of the remaining args
"""

Implement support for RedisJSON using the new mixin pattern.

Implement support for command BITPOS (documentation). Find first bit set or clear in a string

Hi, any estimates when we'll get support for the GETDEL command? Thanks!

Describe the bug
A recent upgrade of our libraries upgraded the redis library from 3.5.3 to 4.2.2 - All tests that were using fakeredis now fail with a KeyError: 'connection_pool' error.

Upon producing the reproduction steps I noticed that there is a compatibility issue between fakeredis 1.7.4 and the current latest version of redis which is redis 4.3.1 so reverted to redis 4.2.2 for the purposes of this replication to avoid this incompatibility where the issue still occurs.

I've tried to look back through fakeredis.FakeStrictRedis -> FakeRedisMixin which references this key in this bit of code: https://github.com/dsoftwareinc/fakeredis-py/blob/master/fakeredis/_server.py#L2804 which is where the test traceback also references.

To Reproduce
I am working in pipenv, so as follows:
Install environment and required packages

pipenv --python 3.8.12 install "fakeredis[lua]~=1.7.4" "redis~=4.2.2" "pytest"

I am using the lua extra to be closer to the application

Create a sample test file with the following contents:

import fakeredis
import pytest


def test_example():

    redis = fakeredis.FakeStrictRedis(decode_responses=True)

    expected = True
    output = True
    assert expected == output

Run the test:

pipenv run pytest test_example.py

Review the output:

lmove operation is a new feature in redis version 6.2.0
It is similar to RPOPLPUSH, but instead it always poping and pushing from both side of the list independently
I am happy to implement it myself, I already have started a branch for this if you give me permission to do so

Describe the bug
The latest (at the time of this writing) release fakeredis-1.7.4 is completely broken on CPython 3.8.

To Reproduce
Assuming docker is available, simply run

docker run --rm -it python:3.8 /bin/bash -c "pip install fakeredis; python -c 'import fakeredis; fakeredis.FakeRedis()'"

<...>
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/local/lib/python3.8/site-packages/fakeredis/_server.py", line 2804, in __init__
    if not bound.arguments['connection_pool']:
KeyError: 'connection_pool'

Interestingly, CPython 3.9 works fine.

Expected behavior
Expected to be able to initialize an instance of fakeredis.FakeRedis.

Hiya and thanks for this library.

The issue is that it doesn't play nice with type checkers - because its missing a py.typed file. The fx is simple - add a py.typed file (its an empty file) into the source folder of the lib, and bundle it as part of the wheel. You can find instructions in the mypy docs.

Cheers.

lupa = { version = "^1.13", optional = true }
redis = "<=4.3.1"
aioredis = { version = "^2.0.1", optional = true }

[tool.poetry.extras]
lua = ["lupa"]
aioredis = ["aioredis"]

I'm getting an error when I try to import using the latest version:
