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.

You are evaluating a software engineering task for repository boto/botocore.
Problem Statement:
Dynamodb local uses HTTPS instead of HTTP
In our endpoints.json we have:
```
"local": {
"hostname": "localhost:8000",
"protocols": [
"http"
],
"credentialScope": {
"region": "us-east-1"
}
}
```
However, creating a client with this region will use HTTPS:
```
>>> import botocore.session
>>> botocore.session.get_session().create_client('dynamodb', 'local').list_tables()
...
botocore.vendored.requests.exceptions.SSLError: [SSL: UNKNOWN_PROTOCOL] unknown protocol (_ssl.c:581)
```
My best guess is that we're not honoring the `protocol` key from endpoints.json when creating clients.
## 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 `botocore` does not honor the `protocols` key in `endpoints.json` when creating a client for `dynamodb` with the `local` region/endpoint. Specifically, it's using HTTPS instead of HTTP.
The `endpoints.json` entry for `local` in `dynamodb` (probably, or global) should be used to determine the protocol.
Let's start by finding where `endpoints.json` is used and how the endpoint URL is constructed.
The problem statement mentions `botocore.session.get_session().create_client('dynamodb', 'local')`.
First, I'll look for where the endpoint URL is constructed and where the protocol is handled.
I suspect `botocore/endpoint.py` or `botocore/client.py`.
Let's search for "protocols" in `botocore/` to see how it's used.

Wait, the `grep` for "protocols" didn't seem to find anything related to HTTP/HTTPS protocols in the way I expected (like endpoint protocol). It found things related to "rest protocols" (serialization). Let's search for "protocol" instead, or search for where `endpoints.json` is loaded. `botocore/endpoint.py` seems like a good place to start. Let's see if `botocore/endpoint.py` uses the `protocols` key from the endpoint data.

In `_create_endpoint`:
```python
def _create_endpoint(self, resolved, service_name, region_name,\n endpoint_url, is_secure):\n region_name, signing_region = self._pick_region_values(\n resolved, region_name, endpoint_url)\n if endpoint_url is None:\n # Use the sslCommonName over the hostname for Python 2.6 compat.\n hostname = resolved.get('sslCommonName', resolved.get('hostname'))\n endpoint_url = self._make_url(hostname, is_secure)\n```
And `_make_url`:
```python
def _make_url(self, hostname, is_secure):\n endpoint_url = 'https://' if is_secure else 'http://'\n return endpoint_url + hostname
```
It seems `is_secure` is used to decide whether to use `https://` or `http://`.
`is_secure` is passed from `ClientCreator._get_client_args`, which gets it from `session.create_client(..., use_ssl=True)`.
The `resolved` object contains the data from `endpoints.json` for the given service and region.
The user said:
```json
"local": {
"hostname": "localhost:8000",
"protocols": [
"http"
],
"credentialScope": {
"region": "us-east-1"
}
}
```
So `resolved` should have `"protocols": ["http"]`.
Currently, `_create_endpoint` doesn't look at `resolved['protocols']`. It just uses `is_secure`.
If `resolved['protocols']` is present and contains 'http', but not 'https', we should probably set `is_secure` to `False` if it was `True`.
Actually, if `resolved['protocols']` is provided, it should probably be the source of truth for whether HTTPS is supported/required.
Wait, `is_secure` is a user preference (via `create_client(use_ssl=...)`). But if the endpoint data says it only supports `http`, then `is_secure=True` should be overridden, or at least we should check if `https` is in the supported protocols.
If `resolved` has `protocols`, we should check if `is_secure` is compatible with it.
If `is_secure` is `True` (default), but `protocols` only contains `http`, we should use `http`.
Let's see how `_make_url` could be changed, or how `_create_endpoint` can adjust `is_secure`.
In `_create_endpoint`:
```python
def _create_endpoint(self, resolved, service_name, region_name,\n endpoint_url, is_secure):\n region_name, signing_region = self._pick_region_values(\n resolved, region_name, endpoint_url)\n if endpoint_url is None:\n # Use the sslCommonName over the hostname for Python 2.6 compat.\n hostname = resolved.get('sslCommonName', resolved.get('hostname'))\n endpoint_url = self._make_url(hostname, is_secure)\n```
We should check `resolved.get('protocols')`.
If `resolved.get('protocols')` is present:
- If `is_secure` is `True` and `'https'` is NOT in `protocols`, then `is_secure` should be `False`.
- If `is_secure` is `False` and `'http'` is NOT in `protocols`, then `is_secure` should be `True` (or maybe raise an error, but typically botocore tries to be flexible).
Wait, if `resolved['protocols']` is `['http']`, it means the endpoint ONLY supports HTTP. So if the user requested HTTPS (`is_secure=True`), it should probably be downgraded to HTTP.
Let's check what `resolved` exactly contains. It comes from `self.endpoint_resolver.construct_endpoint(service_name, region_name)`.
I'll create a reproduction script to confirm the behavior.

Wait, why am I getting this `TypeError` just by calling `create_client`?
```python
client = botocore.session.get_session().create_client('dynamodb', 'local')
```
Let's look at `create_client` again.
```python
client = client_creator.create_client(
service_name=service_name, region_name=region_name,
is_secure=use_ssl, endpoint_url=endpoint_url, verify=verify,
credentials=credentials, scoped_config=self.get_scoped_config(),
client_config=config, api_version=api_version)
return client
```
And `ClientCreator.create_client`:
```python
def create_client(self, service_name, region_name, is_secure=True,
endpoint_url=None, verify=None,
credentials=None, scoped_config=None,
api_version=None,
client_config=None):
service_model = self._load_service_model(service_name, api_version)
cls = self._create_client_class(service_name, service_model)
client_args = self._get_client_args(
service_model, region_name, is_secure, endpoint_url,
verify, credentials, scoped_config, client_config)
return cls(**client_args)
```
The `cls` is a `BaseClient` subclass.
Wait, if I'm seeing `_send_request() takes 5 positional arguments but 6 were given`, it might be happening during the `cls(**client_args)` call if something is triggering a request? No, `create_client` should not make a request.
Let me try a simpler reproduction.

Yes, `_make_url` just uses `is_secure`.
So in `_create_endpoint`, we need to adjust `is_secure` based on `resolved.get('protocols')`.
If `protocols` is present in `resolved`:
1. If `is_secure` is `True` (default) and `https` is in `protocols`, then keep `is_secure = True`.
2. If `is_secure` is `True` and `https` is NOT in `protocols`, but `http` is, then set `is_secure = False`.
3. If `is_secure` is `False` and `http` is in `protocols`, then keep `is_secure = False`.
4. If `is_secure` is `False` and `http` is NOT in `protocols`, but `https` is, then set `is_secure = True`.
5. If `protocols` is empty or none of the above match, maybe fallback to `is_secure` or raise an error? But `endpoints.json` usually has it.
Wait, simpler logic:
If `protocols` is present:
- If `is_secure` is `True`:
- Use `https` if it's in `protocols`.
- Otherwise use `http` if it's in `protocols`.
- Otherwise, keep `is_secure` as is (or maybe this is an invalid state).
- If `is_secure` is `False`:
- Use `http` if it's in `protocols`.
- Otherwise use `https` if it's in `protocols`.
- Otherwise, keep `is_secure` as is.
Actually, it's even simpler:
If `protocols` is present, we should only allow protocols that are in that list.
If `is_secure` is `True` and `https` is in `protocols`, then it's `https`.
If `is_secure` is `False` and `http` is in `protocols`, then it's `http`.
What if `is_secure` is `True` but `https` is NOT in `protocols`? Then we should check if `http` is.
Let's see:
```python
protocols = resolved.get('protocols')
if protocols:
if is_secure and 'https' in protocols:
pass
elif not is_secure and 'http' in protocols:
pass
elif 'https' in protocols:
is_secure = True
elif 'http' in protocols:
is_secure = False
```
Wait, let's refine:
```python
protocols = resolved.get('protocols')
if protocols:
if is_secure:
if 'https' not in protocols:
is_secure = 'http' in protocols
else:
if 'http' not in protocols:
is_secure = 'https' in protocols
```
If `is_secure` is `True` and `https` is NOT in `protocols`, we check if `http` is in `protocols`. If so, `is_secure` becomes `True` if `http` is in `protocols`? No, `is_secure` should be `False` if we use `http`.
Correct logic:
```python
protocols = resolved.get('protocols')
if protocols:
if is_secure:
if 'https' not in protocols:
is_secure = False if 'http' in protocols else is_secure
else:
if 'http' not in protocols:
is_secure = True if 'https' in protocols else is_secure
```
Actually, if `protocols` only contains `['http']` and `is_secure` is `True`, we MUST use `http`.
If `protocols` only contains `['https']` and `is_secure` is `False`, we MUST use `https`.
If `protocols` contains both, we use `is_secure` as a preference.
If `protocols` contains neither, we use `is_secure` as is.
So:
```python
protocols = resolved.get('protocols')
if protocols:
if 'https' in protocols and 'http' in protocols:
pass # keep is_secure as is
elif 'https' in protocols:
is_secure = True
elif 'http' in protocols:
is_secure = False
```
This seems correct and cleaner.
Wait, what if `protocols` is `[]` (empty list)? Then it keeps `is_secure` as is.
Let's check if `resolved` can have `protocols` as `None` or something else. `endpoints.json` typically has it as a list of strings.
Let's apply this to `_create_endpoint` and `_assume_endpoint`?
Wait, `_assume_endpoint` is called when `resolved` is `None` or not found. In `_assume_endpoint`, we don't have `resolved` (the `metadata` passed to `_create_result` is `{}`). So we can't check `protocols` there. That's expected since we're "assuming" the endpoint.
Let's verify this logic with the DynamoDB local case:
`resolved` has `protocols: ['http']`. `is_secure` is `True`.
`'https' in protocols` is `False`.
`'http' in protocols` is `True`.
So `is_secure` becomes `False`.
`_make_url(hostname, False)` returns `http://localhost:8000`. Correct!
What if `is_secure` was `False`?
`'https' in protocols` is `False`.
`'http' in protocols` is `True`.
`is_secure` becomes `False`. Correct!
What if `protocols` was `['https']` and `is_secure` was `False`?
`'https' in protocols` is `True`.
`is_secure` becomes `True`. Correct!
What if `protocols` was `['http', 'https']` and `is_secure` was `True`?
`'https' in protocols` and `'http' in protocols` is `True`.
`is_secure` remains `True`. Correct!
One more thing: `_create_endpoint` is also used in other places?
Let's see if there are other places that use `protocols`.
I'll search for `protocols` in `botocore`.

4. If `is_secure` is `False` and `http` is NOT in `protocols`, but `https` is, then set `is_secure = True`.
5. If `protocols` is empty or none of the above match, maybe fallback to `is_secure` or raise an error? But `endpoints.json` usually has it.
Wait, simpler logic:
If `protocols` is present:
- If `is_secure` is `True`:
- Use `https` if it's in `protocols`.
- Otherwise use `http` if it's in `protocols`.
- Otherwise, keep `is_secure` as is (or maybe this is an invalid state).
- If `is_secure` is `False`:
- Use `http` if it's in `protocols`.
- Otherwise use `https` if it's in `protocols`.
- Otherwise, keep `is_secure` as is.
Actually, it's even simpler:
If `protocols` is present, we should only allow protocols that are in that list.
If `is_secure` is `True` and `https` is in `protocols`, then it's `https`.
If `is_secure` is `False` and `http` is in `protocols`, then it's `http`.
What if `is_secure` is `True` but `https` is NOT in `protocols`? Then we should check if `http` is.
Let's see:
```python
protocols = resolved.get('protocols')
if protocols:
if is_secure and 'https' in protocols:
pass
elif not is_secure and 'http' in protocols:
pass
elif 'https' in protocols:
is_secure = True
elif 'http' in protocols:
is_secure = False
```
Wait, let's refine:
```python
protocols = resolved.get('protocols')
if protocols:
if is_secure:
if 'https' not in protocols:
is_secure = 'http' in protocols
else:
if 'http' not in protocols:
is_secure = 'https' in protocols
```
If `is_secure` is `True` and `https` is NOT in `protocols`, we check if `http` is in `protocols`. If so, `is_secure` becomes `True` if `http` is in `protocols`? No, `is_secure` should be `False` if we use `http`.
Correct logic:
```python
protocols = resolved.get('protocols')
if protocols:
if is_secure:
if 'https' not in protocols:
is_secure = False if 'http' in protocols else is_secure
else:
if 'http' not in protocols:
is_secure = True if 'https' in protocols else is_secure
```
Actually, if `protocols` only contains `['http']` and `is_secure` is `True`, we MUST use `http`.
If `protocols` only contains `['https']` and `is_secure` is `False`, we MUST use `https`.
If `protocols` contains both, we use `is_secure` as a preference.
If `protocols` contains neither, we use `is_secure` as is.
So:
```python
protocols = resolved.get('protocols')
if protocols:
if 'https' in protocols and 'http' in protocols:
pass # keep is_secure as is
elif 'https' in protocols:
is_secure = True
elif 'http' in protocols:
is_secure = False
```
This seems correct and cleaner.
Wait, what if `protocols` is `[]` (empty list)? Then it keeps `is_secure` as is.
Let's check if `resolved` can have `protocols` as `None` or something else. `endpoints.json` typically has it as a list of strings.
Let's apply this to `_create_endpoint` and `_assume_endpoint`?
Wait, `_assume_endpoint` is called when `resolved` is `None` or not found. In `_assume_endpoint`, we don't have `resolved` (the `metadata` passed to `_create_result` is `{}`). So we can't check `protocols` there. That's expected since we're "assuming" the endpoint.
Let's verify this logic with the DynamoDB local case:
`resolved` has `protocols: ['http']`. `is_secure` is `True`.
`'https' in protocols` is `False`.
`'http' in protocols` is `True`.
So `is_secure` becomes `False`.
`_make_url(hostname, False)` returns `http://localhost:8000`. Correct!
What if `is_secure` was `False`?
`'https' in protocols` is `False`.
`'http' in protocols` is `True`.
`is_secure` becomes `False`. Correct!
What if `protocols` was `['https']` and `is_secure` was `False`?
`'https' in protocols` is `True`.
`is_secure` becomes `True`. Correct!
What if `protocols` was `['http', 'https']` and `is_secure` was `True`?
`'https' in protocols` and `'http' in protocols` is `True`.
`is_secure` remains `True`. Correct!
One more thing: `_create_endpoint` is also used in other places?
Let's see if there are other places that use `protocols`.
I'll search for `protocols` in `botocore`.

It seems `protocols` in the context of `endpoints.json` is only handled here in `botocore/client.py` when constructing the URL. Wait, does `botocore` have an `AsyncClient`? The prompt mentioned "parallel or sibling implementations (for example sync + async variants)". Let's check for `AsyncClient`.

No `AsyncClient` in `botocore`. It's likely in `aioboto3` or similar, but not in the `botocore` repository itself. So I just need to fix `_create_endpoint` in `botocore/client.py`. Let's implement the fix.
