You are a principal Python software engineer resolving a repository issue in `/workspace`. Your sole objective is to produce a minimal, root-cause source patch that passes every hidden fail-to-pass and pass-to-pass regression test on the first grading run. ## Critical Environment & Grader Rules 1. **Air-Gapped Sandbox & Available CLI Tools**: No network access. Never run `pip`, `uv`, `conda`, or `git fetch`. Note: `rg` (`ripgrep`) is NOT installed in the container — always use `grep -rn --include="*.py"` for fast exact searches so you never waste a tool call on `command not found`. 2. **Protected Grading Paths**: Before running official verification, the grading harness **strips and reverts all changes** to `tests/`, `test/`, `testing/`, `test_*.py`, `*_test.py`, `conftest.py`, `pyproject.toml`, `setup.cfg`, `pytest.ini`, and `tox.ini`. Every part of your fix MUST reside in non-test production source files. 3. **Untracked File Trap (`git add -N .`)**: `submit_patch` stages ALL untracked files inside `/workspace`! Never leave reproduction or scratch files inside `/workspace` — run reproductions inline via `python3 - <<'PY'` or inside `/tmp/repro.py` in a single `run_command`. 4. **Stdout Truncation Rule**: `run_command` truncates stdout after the first 5,000 characters from the TOP. Always run pytest quietly with short tracebacks: `pytest path/to/test_file.py -k pattern -q --tb=short --no-header` If a test file is large, redirect output to `/tmp/pytest.log` and inspect `tail -n 80 /tmp/pytest.log` so failure tracebacks at the bottom are never cut off. 5. **Strict Pacing Discipline**: `get_status` and `submit_patch` are free and do NOT count toward `max_tool_calls`. Target **16-22 counted tool calls total**, and **begin your first `edit_file` change no later than tool call 15**. Reserve at least 4 calls for verification, `git status --short && git diff`, and submission. ## Execution Protocol ### Phase 1 — Pinpoint Code & Tests Immediately (1-2 tool calls) - The user message already contains `Workspace Layout` — do NOT waste a turn running `ls` on top-level directories. - Run a single compound `run_command` with `grep -rn --include="*.py"` to locate: (a) the exact symbols, error strings, or functions from the problem description, (b) **all parallel or sibling implementations** (for example sync + async variants, `Client` + `AsyncClient`, serializer + deserializer, multiple backends/dialects, base + subclass methods, `__init__.py` / `__all__` exports), and (c) the closest existing unit test files under `tests/`. ### Phase 2 — Deep Read & Spec Anchor (2-5 tool calls) - Use `read_file` with generous `start_line` and `end_line` windows (180-300 lines per call so you read whole modules in fewer calls) on the target function/class, callers, type annotations, and neighboring tests. - Before editing, verify every explicit and implicit requirement from the issue: exact parameter names, defaults, boundary/domain edge cases, exception types/messages, `None` vs empty collection vs falsy (`0`, `False`, `""`) semantics, mutability/copying, and return types. ### Phase 3 — Reproduce Bug in One Call (1 tool call) - Run ONE concise command (`python3 - <<'PY' ... PY` or targeted `pytest ... -q --tb=short --no-header`) via `run_command` to observe the exact pre-fix failure. Do NOT spend multiple tool calls writing separate reproduction scripts. ### Phase 4 — Surgical Implementation Across All Parallel Paths (1-4 tool calls) - Begin editing by tool call 15! Use `edit_file` with 4-6 lines of exact surrounding context copied from `read_file`. - Update ALL parallel codepaths (sync/async, multiple classes/dialects, type hints) consistently so partial fixes do not fail sibling tests. - **2-Strike Edit Rule**: If `edit_file` fails twice on the same block due to whitespace or escaping, do not retry `edit_file` a third time — apply an atomic Python transformation via `run_command` and immediately verify `python3 -m py_compile path/to/file.py`. ### Phase 5 — Edge-Case Verification, Diff Hygiene & Clean Exit (2-4 tool calls) - Run a single compound `run_command` testing both your reproduction + boundary edge cases (`None`, empty input, leading/trailing delimiters, subdomain/prefix boundaries, subclass/async parity) AND the relevant existing `pytest` module(s) with `-q --tb=short --no-header`. - Run `git status --short && git diff` via `run_command`. Confirm: - ZERO untracked (`??`) files in `/workspace` (`rm -f` any untracked workspace files immediately), - ZERO modifications to `tests/` or protected config files (`git checkout -- tests/` if touched), - Minimal, clean diff with valid imports and indentation. - Call `submit_patch` once verification passes, then respond with a brief 2-sentence plain-text summary and make NO further tool calls.

## Task Budget (Session terminates when any budget is exhausted)
- Time allowance: 7.5 minutes
- Tool calls allowance: 30 calls
- Max loop iterations: 40 turns
## Execution Environment Rules
- Single command timeout: 90 seconds (commands exceeding this fail without ending the session)
- Command output limit: 5000 characters
- File view limit: 150 lines per read_file call
- File character limit: 10000 characters per read_file call
- Environment is offline (no network/PyPI access). All repository and test dependencies are ALREADY pre-installed. Do NOT attempt to run pip install or download packages.
## Instructions:
0. All source code is under `/workspace`. Do NOT search outside `/workspace` (e.g. `/usr/`, `/wheels/`, system site-packages). If imports fail, the issue is in the source code under `/workspace`, not in missing system packages.
1. Analyze the problem statement and any provided hints carefully to identify all requested script paths, CLI subcommands, or Python modules.
2. Inspect existing codebase conventions and test files before making edits.
3. Verify your implementation using targeted tests or inline assertions before submitting.
4. Call submit_patch only after your implementation is complete and verified.
5. As your final action, you must return a text-only response reporting your completion to terminate the session.
## Workspace Layout
The repository is located at `/workspace`. Here is the directory tree (up to 3 levels):

The user is reporting an issue where the `cassandra_port` configuration is not working for the Cassandra result backend.
Looking at the provided error:
`NoHostAvailable: ('Unable to connect to any servers', {'localhost': error(111, "Tried connecting to [('localhost', 9042)]. Last error: Connection refused")})`
The user configured `cassandra_port: '61003'`, but the client is trying to connect to port `9042` (the default Cassandra port).
This suggests that `cassandra_port` is either not being passed to the Cassandra driver cluster instantiation or is being ignored/overridden.
I need to check `celery/backends/cassandra.py` to see how `cassandra_port` is handled.

Looking at the code:
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=9042, bundle_path=None, **kwargs):
super().__init__(**kwargs)
if not cassandra:
raise ImproperlyConfigured(E_NO_CASSANDRA)
conf = self.app.conf
self.servers = servers or conf.get('cassandra_servers', None)
self.bundle_path = bundle_path or conf.get(
'cassandra_secure_bundle_path', None)
self.port = port or conf.get('cassandra_port', None)
self.keyspace = keyspace or conf.get('cassandra_keyspace', None)
self.table = table or conf.get('cassandra_table', None)
self.cassandra_options = conf.get('cassandra_options', {})
```
Wait, `port=9042` is a default argument for `__init__`.
If `self.app.conf.get('cassandra_port', None)` is used, and `port` is `9042` (the default), then `port or conf.get('cassandra_port', None)` will ALWAYS be `9042` if `port` is provided as `9042`.
Actually, if `__init__` is called with `port=9042` (which is the default), then `port or conf.get('cassandra_port', None)` will be `9042` unless `port` was passed as `None` or `0` or some other falsy value.
Typically, Celery backends are instantiated with defaults from the app config.
Let's see how `CassandraBackend` is instantiated. It's usually done via some factory or in the app initialization.
If the `CassandraBackend` is instantiated without specifying `port`, it uses the default `port=9042`.
Then `self.port = 9042 or conf.get('cassandra_port', None)` will always be `9042`.
This is exactly the bug. It should be:
```python
self.port = port if port != 9042 else conf.get('cassandra_port', 9042)
```
Or even better, the default value for `port` in `__init__` should be `None`.
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=None, bundle_path=None, **kwargs):
# ...
self.port = port or conf.get('cassandra_port', 9042)
```
Let's check if `port` is ever passed to `__init__` from outside.
In `celery/backends/cassandra.py`, `__reduce__` doesn't include `port`:
```python
def __reduce__(self, args=(), kwargs=None):
kwargs = {} if not kwargs else kwargs
kwargs.update(
{'servers': self.servers,
'keyspace': self.keyspace,
'table': self.table})
return super().__reduce__(args, kwargs)
```
Wait, it's missing `port` in `__reduce__` too! This means it won't be pickled/unpickled correctly if it was set.
But let's focus on the `__init__` first.
If I change `port=9042` to `port=None` in `__init__`, and then use `self.port = port or conf.get('cassandra_port', 9042)`, it should work.
Wait, the user said:
`cassandra_port: '61003'`
Wait, it's a string! The Cassandra driver expect an integer for the port.
If `conf.get('cassandra_port', None)` returns `'61003'`, `self.port` becomes `'61003'`.
Then it is passed to `cassandra.cluster.Cluster(self.servers, port=self.port, ...)`.
Does the `cassandra-driver` accept a string for `port`?
The error says:
`NoHostAvailable: ('Unable to connect to any servers', {'localhost': error(111, "Tried connecting to [('localhost', 9042)]. Last error: Connection refused")})`
It says it tried connecting to `9042`. If it had tried to connect to `'61003'` and the driver didn't like strings, it might have failed earlier or converted it. But it's clearly using `9042`.
Back to the `port=9042` default in `__init__`.
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=9042, bundle_path=None, **kwargs):
# ...
self.port = port or conf.get('cassandra_port', None)
```
If `port` is `9042` (default), and `conf.get('cassandra_port', None)` is `'61003'`, then `self.port` will be `9042` because `9042` is truthy.
So the fix is to make `port` default to `None` in `__init__`.
Let's try to reproduce this. I can't easily run a Cassandra cluster, but I can mock the `cassandra` module and the celery app configuration.

Ah, `self.app.conf` is expected to be an object that supports attribute access, not a dictionary. I should use a `MagicMock` for `app.conf` or a simple object. Also, I need to make sure `app.conf` has `result_serializer` because `BaseBackend.__init__` uses it.

The reproduction is successful. `backend.port` is `9042` because of the default argument in `__init__`.
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=9042, bundle_path=None, **kwargs):
# ...
self.port = port or conf.get('cassandra_port', None)
```
If `port` is `9042`, `self.port` becomes `9042`, regardless of `conf.get('cassandra_port', None)`.
To fix this, I should:
1. Change `port=9042` to `port=None` in `__init__`.
2. Change `self.port = port or conf.get('cassandra_port', None)` to `self.port = port or conf.get('cassandra_port', 9042)`.
Wait, if I change it to `port=None` in `__init__`, then `self.port = port or conf.get('cassandra_port', 9042)` will use the value from `conf` if `port` is `None`, and it will use `9042` if `conf` also doesn't have it. This is correct.
Also, as I noticed before, `__reduce__` is missing `port`. I should add it there too, so that when the backend is pickled, the port is preserved.
```python
def __reduce__(self, args=(), kwargs=None):
kwargs = {} if not kwargs else kwargs
kwargs.update(
{'servers': self.servers,
'keyspace': self.keyspace,
'table': self.table})
return super().__reduce__(args, kwargs)
```
It should be:
```python
def __reduce__(self, args=(), kwargs=None):
kwargs = {} if not kwargs else kwargs
kwargs.update(
{'servers': self.servers,
'port': self.port,
'keyspace': self.keyspace,
'table': self.table})
return super().__reduce__(args, kwargs)
```
Wait, if I add `port` to `__reduce__`, then when it's unpickled, `__init__` will be called with `port=self.port` (where `self.port` might be `61003`).
If I also changed `port=None` in `__init__`, then `self.port = 61003 or conf.get(...)` will be `61003`. Correct.
One more thing: should I also cast `self.port` to `int`? The user provided `'61003'` (a string).
```python
self.port = port or conf.get('cassandra_port', None)
```
If it's a string, it should be converted to `int` if possible.
Actually, let's check if `port` should be an `int`. The Cassandra driver's `Cluster` class expects `port` to be an integer.
If I change it to:
```python
self.port = port or conf.get('cassandra_port', 9042)
try:
self.port = int(self.port)
except (ValueError, TypeError):
pass
```
Or just:
```python
self.port = int(port or conf.get('cassandra_port', 9042))
```
But `conf.get` might return something that's already an int or None.
Let's see how other backends handle ports.
For example, `celery/backends/redis.py` or `celery/backends/mongodb.py`.
Wait, the user just complained that the config doesn't work. The most obvious problem is the `port=9042` default in `__init__`.
Let's verify if I should just change the default and let the user provide an int if they wanted, but they provided a string.
If they provided `'61003'`, and I do `self.port = int(port or conf.get('cassandra_port', 9042))`, it will work.
However, I should be careful not to change the behavior too much.
Actually, let's look at `__init__` again.
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=9042, bundle_path=None, **kwargs):
# ...
self.port = port or conf.get('cassandra_port', None)
```
If I change it to:
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=None, bundle_path=None, **kwargs):
# ...
self.port = port or conf.get('cassandra_port', 9042)
```
And the user has `cassandra_port = '61003'` in their config, `self.port` will be `'61003'`.
Then `cassandra.cluster.Cluster(self.servers, port=self.port, ...)` will be called.
If the `cassandra-driver` handles strings, it's fine. If not, it might be better to cast it.
Let's check if the `cassandra-driver` handles strings for port.
(I don't have the driver source code, but I can try to run a small script with a mock).
Actually, the issue is that the user is seeing a connection to `9042` despite having `61003` in the config. This is clearly due to `port=9042` being truthy in `port or conf.get(...)`.
I'll start by fixing the `__init__` and `__reduce__`.
Wait, if I change `port=9042` to `port=None` in `__init__`, I should also make sure I use a default if both `port` and `conf.get('cassandra_port')` are None.
```python
self.port = port or conf.get('cassandra_port', 9042)
```
This will set `self.port` to `9042` if neither is provided.
Let's double check the current `__init__` again.
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=9042, bundle_path=None, **kwargs):
# ...
self.port = port or conf.get('cassandra_port', None)
```
If `port` is `9042`, `self.port` becomes `9042`.
If `port` is passed as `None` explicitly, `self.port` becomes `conf.get('cassandra_port', None)`. If that's also `None`, then `self.port` is `None`.
And then `cassandra.cluster.Cluster(..., port=None, ...)` might use its own default (which is 9042).
So changing it to:
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=None, bundle_path=None, **kwargs):
# ...
self.port = port or conf.get('cassandra_port', 9042)
```
is a good fix.
Wait, should I cast to `int`? The user provided `'61003'`.
The error message says:
`NoHostAvailable: ('Unable to connect to any servers', {'localhost': error(111, "Tried connecting to [('localhost', 9042)]. Last error: Connection refused")})`
It says it tried `9042`.
If I change the code and the user still provides `'61003'`, and the driver doesn't like strings, it might fail with a different error, or it might work.
Let's update `__init__` and `__reduce__` and see if I can pass the reproduction test (with the fix).

The `ImproperlyConfigured` errors are because I didn't provide `cassandra_servers` or `cassandra_secure_bundle_path` and `cassandra_keyspace` and `cassandra_table` in the test cases. But the first test case passed (it’s the `.` in `E.E`).
So my proposed fix for `__init__` is correct.
Now let's apply it to `celery/backends/cassandra.py`.
I will also add `port` to `__reduce__`.
Wait, I should also cast `self.port` to `int` just in case the user provides a string, although the issue report showed `'61003'`.
Actually, I'll stick to the minimal fix first: change `port=9042` to `port=None` and `self.port = port or conf.get('cassandra_port', 9042)`. And add `port` to `__reduce__`.
Let's check `celery/backends/cassandra.py` again for the lines to be changed.
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=9042, bundle_path=None, **kwargs):
```
to
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=None, bundle_path=None, **kwargs):
```
And
```python
self.port = port or conf.get('cassandra_port', None)
```
to
```python
self.port = port or conf.get('cassandra_port', 9042)
```
And
```python
def __reduce__(self, args=(), kwargs=None):
kwargs = {} if not kwargs else kwargs
kwargs.update(
{'servers': self.servers,
'keyspace': self.keyspace,
'table': self.table})
return super().__reduce__(args, kwargs)
```
to
```python
def __reduce__(self, args=(), kwargs=None):
kwargs = {} if not kwargs else kwargs
kwargs.update(
{'servers': self.servers,
'port': self.port,
'keyspace': self.keyspace,
'table': self.table})
return super().__reduce__(args, kwargs)
```
Wait, if I add `port` to `__reduce__`, then during unpickling, `CassandraBackend`'s `__init__` will be called with `port=self.port`.
Now that I've changed the default `port` to `None`, it will correctly use the passed `port`.

Ah, it seems `reduced` is `(<function unpickle_backend...>, (<class 'celery.backends.cassandra.CassandraBackend'>, (), {'servers': ['localhost'], 'port': 7000, 'keyspace': 'test', 'table': 'test'}))`.
So the kwargs are in `reduced[1][2]`.
Let's just verify the output again.
`Reduced: (<function unpickle_backend at 0x7479f7d9c9d0>, (<class 'celery.backends.cassandra.CassandraBackend'>, (), {'servers': ['localhost'], 'port': 7000, 'keyspace': 'test', 'table': 'test'}))`
Yes, `reduced[1][2]` is the dict.
My `__reduce__` implementation in `celery/backends/cassandra.py` is:
```python
def __reduce__(self, args=(), kwargs=None):
kwargs = {} if not kwargs else kwargs
kwargs.update(
{'servers': self.servers,
'port': self.port,
'keyspace': self.keyspace,
'table': self.table})
return super().__reduce__(args, kwargs)
```
And the output confirms that `port` is now included in the state.
I'm confident with the fix.

The diff looks clean. I have:
1. Changed the default `port` in `__init__` from `9042` to `None`.
2. Changed how `self.port` is assigned to use `conf.get('cassandra_port', 9042)`.
3. Added `port` to `__reduce__`.
This correctly addresses the issue where `cassandra_port` in configuration was being ignored when `port` was not passed to the constructor.
Final check: if `port` is passed as an argument, it takes precedence. If not, `cassandra_port` from config takes precedence. If neither, `9042` is used. This is exactly the desired behavior.

All done.

The bug was caused by `CassandraBackend.__init__` having a default value of `9042` for the `port` argument, which was then used in a logical `or` expression `self.port = port or conf.get('cassandra_port', None)`, making the configuration value ignored. I changed the default `port` to `None` and updated the assignment to use `9042` as the fallback in `conf.get`. Additionally, I added the `port` attribute to the `__reduce__` method to ensure correct serialization and deserialization of the backend.

Looking at the code:
```python

port=9042, bundle_path=None, **kwargs):
super().__init__(**kwargs)
if not cassandra:

self.keyspace = keyspace or conf.get('cassandra_keyspace', None)
self.table = table or conf.get('cassandra_table', None)
self.cassandra_options = conf.get('cassandra_options', {})
```
Wait, `port=9042` is a default argument for `__init__`.
If `self.app.conf.get('cassandra_port', None)` is used, and `port` is `9042` (the default), then `port or conf.get('cassandra_port', None)` will ALWAYS be `9042` if `port` is provided as `9042`.
Actually, if `__init__` is called with `port=9042` (which is the default), then `port or conf.get('cassandra_port', None)` will be `9042` unless `port` was passed as `None` or `0` or some other falsy value.
Typically, Celery backends are instantiated with defaults from the app config.
Let's see how `CassandraBackend` is instantiated. It's usually done via some factory or in the app initialization.
If the `CassandraBackend` is instantiated without specifying `port`, it uses the default `port=9042`.
Then `self.port = 9042 or conf.get('cassandra_port', None)` will always be `9042`.
This is exactly the bug. It should be:
```python
self.port = port if port != 9042 else conf.get('cassandra_port', 9042)
```
Or even better, the default value for `port` in `__init__` should be `None`.
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=None, bundle_path=None, **kwargs):
# ...
self.port = port or conf.get('cassandra_port', 9042)
```
Let's check if `port` is ever passed to `__init__` from outside.
In `celery/backends/cassandra.py`, `__reduce__` doesn't include `port`:
```python
def __reduce__(self, args=(), kwargs=None):
kwargs = {} if not kwargs else kwargs
kwargs.update(
{'servers': self.servers,
'keyspace': self.keyspace,
'table': self.table})
return super().__reduce__(args, kwargs)
```
Wait, it's missing `port` in `__reduce__` too! This means it won't be pickled/unpickled correctly if it was set.
But let's focus on the `__init__` first.
If I change `port=9042` to `port=None` in `__init__`, and then use `self.port = port or conf.get('cassandra_port', 9042)`, it should work.
Wait, the user said:
`cassandra_port: '61003'`
Wait, it's a string! The Cassandra driver expect an integer for the port.
If `conf.get('cassandra_port', None)` returns `'61003'`, `self.port` becomes `'61003'`.
Then it is passed to `cassandra.cluster.Cluster(self.servers, port=self.port, ...)`.
Does the `cassandra-driver` accept a string for `port`?
The error says:
`NoHostAvailable: ('Unable to connect to any servers', {'localhost': error(111, "Tried connecting to [('localhost', 9042)]. Last error: Connection refused")})`
It says it tried connecting to `9042`. If it had tried to connect to `'61003'` and the driver didn't like strings, it might have failed earlier or converted it. But it's clearly using `9042`.
Back to the `port=9042` default in `__init__`.
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=9042, bundle_path=None, **kwargs):
# ...
self.port = port or conf.get('cassandra_port', None)
```
If `port` is `9042` (default), and `conf.get('cassandra_port', None)` is `'61003'`, then `self.port` will be `9042` because `9042` is truthy.
So the fix is to make `port` default to `None` in `__init__`.
Let's try to reproduce this. I can't easily run a Cassandra cluster, but I can mock the `cassandra` module and the celery app configuration.
Looking at the code:
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=9042, bundle_path=None, **kwargs):

The reproduction is successful. `backend.port` is `9042` because of the default argument in `__init__`.
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=9042, bundle_path=None, **kwargs):
# ...
self.port = port or conf.get('cassandra_port', None)
```
If `port` is `9042`, `self.port` becomes `9042`, regardless of `conf.get('cassandra_port', None)`.
To fix this, I should:
1. Change `port=9042` to `port=None` in `__init__`.
2. Change `self.port = port or conf.get('cassandra_port', None)` to `self.port = port or conf.get('cassandra_port', 9042)`.
Wait, if I change it to `port=None` in `__init__`, then `self.port = port or conf.get('cassandra_port', 9042)` will use the value from `conf` if `port` is `None`, and it will use `9042` if `conf` also doesn't have it. This is correct.
Also, as I noticed before, `__reduce__` is missing `port`. I should add it there too, so that when the backend is pickled, the port is preserved.
```python
def __reduce__(self, args=(), kwargs=None):
kwargs = {} if not kwargs else kwargs
kwargs.update(
{'servers': self.servers,
'keyspace': self.keyspace,
'table': self.table})
return super().__reduce__(args, kwargs)
```
It should be:
```python
def __reduce__(self, args=(), kwargs=None):
kwargs = {} if not kwargs else kwargs
kwargs.update(
{'servers': self.servers,
'port': self.port,
'keyspace': self.keyspace,
'table': self.table})
return super().__reduce__(args, kwargs)
```
Wait, if I add `port` to `__reduce__`, then when it's unpickled, `__init__` will be called with `port=self.port` (where `self.port` might be `61003`).
If I also changed `port=None` in `__init__`, then `self.port = 61003 or conf.get(...)` will be `61003`. Correct.
One more thing: should I also cast `self.port` to `int`? The user provided `'61003'` (a string).
```python
self.port = port or conf.get('cassandra_port', None)
```
If it's a string, it should be converted to `int` if possible.
Actually, let's check if `port` should be an `int`. The Cassandra driver's `Cluster` class expects `port` to be an integer.
If I change it to:
```python
self.port = port or conf.get('cassandra_port', 9042)
try:
self.port = int(self.port)
except (ValueError, TypeError):
pass
```
Or just:
```python
self.port = int(port or conf.get('cassandra_port', 9042))
```
But `conf.get` might return something that's already an int or None.
Let's see how other backends handle ports.
For example, `celery/backends/redis.py` or `celery/backends/mongodb.py`.
Wait, the user just complained that the config doesn't work. The most obvious problem is the `port=9042` default in `__init__`.
Let's verify if I should just change the default and let the user provide an int if they wanted, but they provided a string.
If they provided `'61003'`, and I do `self.port = int(port or conf.get('cassandra_port', 9042))`, it will work.
However, I should be careful not to change the behavior too much.
Actually, let's look at `__init__` again.
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=9042, bundle_path=None, **kwargs):
# ...
self.port = port or conf.get('cassandra_port', None)
```
If I change it to:
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=None, bundle_path=None, **kwargs):
# ...
self.port = port or conf.get('cassandra_port', 9042)
```
And the user has `cassandra_port = '61003'` in their config, `self.port` will be `'61003'`.
Then `cassandra.cluster.Cluster(self.servers, port=self.port, ...)` will be called.
If the `cassandra-driver` handles strings, it's fine. If not, it might be better to cast it.
Let's check if the `cassandra-driver` handles strings for port.
(I don't have the driver source code, but I can try to run a small script with a mock).
Actually, the issue is that the user is seeing a connection to `9042` despite having `61003` in the config. This is clearly due to `port=9042` being truthy in `port or conf.get(...)`.
I'll start by fixing the `__init__` and `__reduce__`.
Wait, if I change `port=9042` to `port=None` in `__init__`, I should also make sure I use a default if both `port` and `conf.get('cassandra_port')` are None.
```python
self.port = port or conf.get('cassandra_port', 9042)
```
This will set `self.port` to `9042` if neither is provided.
Let's double check the current `__init__` again.
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=9042, bundle_path=None, **kwargs):
# ...
self.port = port or conf.get('cassandra_port', None)
```
If `port` is `9042`, `self.port` becomes `9042`.
If `port` is passed as `None` explicitly, `self.port` becomes `conf.get('cassandra_port', None)`. If that's also `None`, then `self.port` is `None`.
And then `cassandra.cluster.Cluster(..., port=None, ...)` might use its own default (which is 9042).
So changing it to:
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=None, bundle_path=None, **kwargs):
# ...
self.port = port or conf.get('cassandra_port', 9042)
```
is a good fix.
Wait, should I cast to `int`? The user provided `'61003'`.
The error message says:
`NoHostAvailable: ('Unable to connect to any servers', {'localhost': error(111, "Tried connecting to [('localhost', 9042)]. Last error: Connection refused")})`
It says it tried `9042`.
If I change the code and the user still provides `'61003'`, and the driver doesn't like strings, it might fail with a different error, or it might work.
Let's update `__init__` and `__reduce__` and see if I can pass the reproduction test (with the fix).
The reproduction is successful. `backend.port` is `9042` because of the default argument in `__init__`.
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=9042, bundle_path=None, **kwargs):
# ...
self.port = port or conf.get('cassandra_port', None)
```
If `port` is `9042`, `self.port` becomes `9042`, regardless of `conf.get('cassandra_port', None)`.
To fix this, I should:
1. Change `port=9042` to `port=None` in `__init__`.
2. Change `self.port = port or conf.get('cassandra_port', None)` to `self.port = port or conf.get('cassandra_port', 9042)`.
Wait, if I change it to `port=None` in `__init__`, then `self.port = port or conf.get('cassandra_port', 9042)` will use the value from `conf` if `port` is `None`, and it will use `9042` if `conf` also doesn't have it. This is correct.
Also, as I noticed before, `__reduce__` is missing `port`. I should add it there too, so that when the backend is pickled, the port is preserved.
```python
def __reduce__(self, args=(), kwargs=None):
kwargs = {} if not kwargs else kwargs
kwargs.update(
{'servers': self.servers,
'keyspace': self.keyspace,
'table': self.table})
return super().__reduce__(args, kwargs)
```
It should be:
```python
def __reduce__(self, args=(), kwargs=None):
kwargs = {} if not kwargs else kwargs
kwargs.update(
{'servers': self.servers,
'port': self.port,
'keyspace': self.keyspace,
'table': self.table})
return super().__reduce__(args, kwargs)
```
Wait, if I add `port` to `__reduce__`, then when it's unpickled, `__init__` will be called with `port=self.port` (where `self.port` might be `61003`).
If I also changed `port=None` in `__init__`, then `self.port = 61003 or conf.get(...)` will be `61003`. Correct.
One more thing: should I also cast `self.port` to `int`? The user provided `'61003'` (a string).
```python
self.port = port or conf.get('cassandra_port', None)
```
If it's a string, it should be converted to `int` if possible.
Actually, let's check if `port` should be an `int`. The Cassandra driver's `Cluster` class expects `port` to be an integer.
If I change it to:
```python
self.port = port or conf.get('cassandra_port', 9042)
try:
self.port = int(self.port)
except (ValueError, TypeError):
pass
```
Or just:
```python
self.port = int(port or conf.get('cassandra_port', 9042))
```
But `conf.get` might return something that's already an int or None.
Let's see how other backends handle ports.
For example, `celery/backends/redis.py` or `celery/backends/mongodb.py`.
Wait, the user just complained that the config doesn't work. The most obvious problem is the `port=9042` default in `__init__`.
Let's verify if I should just change the default and let the user provide an int if they wanted, but they provided a string.
If they provided `'61003'`, and I do `self.port = int(port or conf.get('cassandra_port', 9042))`, it will work.
However, I should be careful not to change the behavior too much.
Actually, let's look at `__init__` again.
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=9042, bundle_path=None, **kwargs):
# ...
self.port = port or conf.get('cassandra_port', None)
```
If I change it to:
```python
def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
port=None, bundle_path=None, **kwargs):
# ...
self.port = port or conf.get('cassandra_port', 9042)
```
And the user has `cassandra_port = '61003'` in their config, `self.port` will be `'61003'`.
Then `cassandra.cluster.Cluster(self.servers, port=self.port, ...)` will be called.
If the `cassandra-driver` handles strings, it's fine. If not, it might be better to cast it.
Let's check if the `cassandra-driver` handles strings for port.

2. Changed how `self.port` is assigned to use `conf.get('cassandra_port', 9042)`.
3. Added `port` to `__reduce__`.
This correctly addresses the issue where `cassandra_port` in configuration was being ignored when `port` was not passed to the constructor.
Final check: if `port` is passed as an argument, it takes precedence. If not, `cassandra_port` from config takes precedence. If neither, `9042` is used. This is exactly the desired behavior.The diff looks clean. I have:
1. Changed the default `port` in `__init__` from `9042` to `None`.
2. Changed how `self.port` is assigned to use `conf.get('cassandra_port', 9042)`.
3. Added `port` to `__reduce__`.
