System instructions 4,822 characters
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 prompt 5,435 characters
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.

The user is reporting an issue where `botocore` is using HTTPS instead of HTTP when the region is set to 'local' for DynamoDB, despite `endpoints.json` specifying `http` as the protocol.

The issue seems to be in how the endpoint is resolved or how the client is created.

Let's start by exploring the codebase to find where endpoints are handled and how the protocol is determined.

I'll search for "protocols" or "endpoint" in `botocore` files.

The search for `protocols` didn't give a clear lead to where the protocol (http/https) of the endpoint is determined. The `protocols` in `endpoints.json` usually refers to the communication protocol (like `http`, `https`).

Let's look at how the client handles the endpoint and the protocol. I'll search for where `endpoints.json` might be used and how `hostname` is processed.

I'll search for where the endpoint is constructed. `botocore/endpoint.py` seems like a good place.

`botocore/endpoint.py` defines the `Endpoint` class. The `create_endpoint` method takes `endpoint_url`.

Wait, the issue says the `endpoints.json` has:
```json
            "local": {
              "hostname": "localhost:8000",

`botocore/client.py` has `_make_url(self, hostname, is_secure)`. This looks promising.
Also `botocore/regions.py` seems involved in endpoint resolution.

`botocore/client.py` has `_make_url(self, hostname, is_secure)`. This looks promising. Also `botocore/regions.py` seems involved in endpoint resolution. Let's examine `botocore/client.py` around `_make_url`. <channel|><|tool_call>call:read_file{filepath:<|"|>botocore/client.py<|"|>,start_line:280,end_line:350}<tool_call|><|tool_response>

In `_create_endpoint` and `_assume_endpoint`, `is_secure` is used in `_make_url(hostname, is_secure)`.

`_make_url` is simple:
```python
    def _make_url(self, hostname, is_secure):
        endpoint_url = 'https://' if is_secure else 'http://'
        return endpoint_url + hostname
```

So the question is: where does `is_secure` come from?
Looking at `_create_endpoint(self, resolved, service_name, region_name, endpoint_url, is_secure)`, it's passed as an argument.

I need to find where `_create_endpoint` is called.

In `_get_client_args`:
```python
        endpoint_bridge = ClientEndpointBridge(
            self._endpoint_resolver, scoped_config, client_config,
            service_model.metadata.get('signingName'))
        endpoint_config = endpoint_bridge.resolve(
            service_name, region_name, endpoint_url, is_secure)
```

And `is_secure` is passed into `_get_client_args`. Let's see where `_get_client_args` is called.

Actually, the problem is that `is_secure` defaults to `True` in `ClientEndpointBridge.resolve`, and it seems it's not being updated based on the `protocols` defined in `endpoints.json`.

Look at `ClientEndpointBridge.resolve`:
```python
    def resolve(self, service_name, region_name=None, endpoint_url=None,
                is_secure=True):
        region_name = self._check_default_region(service_name, region_name)
        resolved = self.endpoint_resolver.construct_endpoint(
            service_name, region_name)
        if resolved:
            return self._create_endpoint(
                resolved, service_name, region_name, endpoint_url, is_secure)
        else:
            return self._assume_endpoint(service_name, region_name,
                                         endpoint_url, is_secure)
```

`resolved` is the result of `self.endpoint_resolver.construct_endpoint(service_name, region_name)`.
`resolved` is what comes from `endpoints.json` (via the resolver).
If `resolved` contains information about the protocol, it should be used to determine if the request is secure.

In `_create_endpoint`:
```python
    def _create_endpoint(self, resolved, service_name, region_name,
                         endpoint_url, is_secure):
        region_name, signing_region = self._pick_region_values(
            resolved, region_name, endpoint_url)
        if endpoint_url is None:
            # Use the sslCommonName over the hostname for Python 2.6 compat.
            hostname = resolved.get('sslCommonName', resolved.get('hostname'))
            endpoint_url = self._make_url(hostname, is_secure)
        # ...
```

Here `is_secure` is used to create the `endpoint_url` via `_make_url(hostname, is_secure)`.
But `is_secure` is just passed from `resolve`.

If `resolved` (which corresponds to the entry in `endpoints.json`) has a `protocols` key, we should use it to determine `is_secure`.

Let's see `botocore/regions.py` to see how `construct_endpoint` works, because `self.endpoint_resolver` is likely an instance of something from `regions.py`.

But `is_secure` is just passed from `resolve`. If `resolved` (which corresponds to the entry in `endpoints.json`) has a `protocols` key, we should use it to determine `is_secure`. Let's see `botocore/regions.py` to see how `construct_endpoint` works, because `self.endpoint_resolver` is likely an instance of something from `regions.py`. <channel|><|tool_call>call:run_command{command:<|"|>grep -rn "construct_endpoint" botocore/regions.py<|"|>}<tool_call|><|tool_response>

So `_resolve` returns the endpoint data from `endpoints.json`, merged with defaults.
If `protocols` is in the endpoint data, it will be in the `result`.

Now let's go back to `botocore/client.py` and `ClientEndpointBridge.resolve`.

```python
    def resolve(self, service_name, region_name=None, endpoint_url=None,
                is_secure=True):
        region_name = self._check_default_region(service_name, region_name)
        resolved = self.endpoint_resolver.construct_endpoint(
            service_name, region_name)
        if resolved:
            return self._create_endpoint(
                resolved, service_name, region_name, endpoint_url, is_secure)
        else:
            return self._assume_endpoint(service_name, region_name,
                                         endpoint_url, is_secure)
```

And `_create_endpoint`:

```python
    def _create_endpoint(self, resolved, service_name, region_name,
                         endpoint_url, is_secure):
        region_name, signing_region = self._pick_region_values(
            resolved, region_name, endpoint_url)
        if endpoint_url is None:
            # Use the sslCommonName over the hostname for Python 2.6 compat.
            hostname = resolved.get('sslCommonName', resolved.get('hostname'))
            endpoint_url = self._make_url(hostname, is_secure)
```

If `resolved` contains `protocols`, we should probably use it to override `is_secure`.
The `protocols` in `endpoints.json` is a list of strings.

For example:
```json
            "local": {
              "hostname": "localhost:8000",
              "protocols": [
                "http"
              ],
              ...
            }
```

So if `protocols` is present in `resolved`, we should check if `https` is in it.
Wait, if 'http' is the only protocol, then `is_secure` should be `False`.
If 'https' is present, then `is_secure` should be `True`.
Usually, the first element of `protocols` might be the preferred one, or any entry.

Let's see what other endpoints have `protocols`.
The problem statement says `protocols` is a list.

If we have `protocols`, and `https` is not in it, then it must be `http` (or something else, but usually it's http/https).
Actually, if `protocols` is specified, we should probably prefer it over the default `is_secure` value.

If `protocols` is present:
- if 'https' in protocols, then `is_secure = True` (unless we want to prefer http if both are present? usually https is preferred).
- if 'https' not in protocols and 'http' in protocols, then `is_secure = False`.

Actually, a simpler way: if `protocols` is present, the protocol to use should be determined by it.

Wait, if `is_secure` is passed as `True` (the default), but `protocols` only contains `['http']`, then it should be `False`.
If `is_secure` is passed as `False`, but `protocols` only contains `['https']`, then it should be `True`.

Actually, if `protocols` is present in `resolved`, it should probably dictate whether `is_secure` is True or False.

Let's check how this is handled in other AWS SDKs if possible, or just implement it logically.
If `protocols` is provided in the endpoint metadata, it should be honored.

Let's see if there are other places where `protocols` is used in `botocore`.

I'll search for `protocols` again, but this time looking for `['http']` or `['https']`.

Okay, many endpoints have `protocols`.

Now let's see how `ClientEndpointBridge.resolve` and `_create_endpoint` should change.

If `resolved` contains `protocols`, we should use it to determine `is_secure`.

```python
    def _create_endpoint(self, resolved, service_name, region_name,
                         endpoint_url, is_secure):
        region_name, signing_region = self._pick_region_values(
            resolved, region_name, endpoint_url)
        if endpoint_url is None:
            # Use the sslCommonName over the hostname for Python 2.6 compat.
            hostname = resolved.get('sslCommonName', resolved.get('hostname'))
            
            # Check if protocols are specified in the resolved endpoint
            protocols = resolved.get('protocols')
            if protocols:
                # If 'https' is in protocols, we can use it. 
                # If not, and 'http' is in protocols, we MUST use 'http'.
                is_secure = 'https' in protocols
            
            endpoint_url = self._make_url(hostname, is_secure)
```

Wait, what if `is_secure` was passed as `False` by the user?
If the user explicitly sets `is_secure=False`, should we still use `https` if it's in `protocols`?
Usually, user preference should win, OR the endpoint constraints should win.

Looking at `resolve`:
```python
    def resolve(self, service_name, region_name=None, endpoint_url=None,
                is_secure=True):
```
`is_secure` defaults to `True`.

If the user calls it with `is_secure=False`, they probably want HTTP.
If the endpoint only supports HTTPS, then HTTPS should be used.

Wait, if `protocols` is specified in `endpoints.json`, it describes what the server supports.

If `protocols` is `['http']`, then `is_secure` should be `False`.
If `protocols` is `['https']`, then `is_secure` should be `True`.
If `protocols` is `['http', 'https']`, then we can use either, but we should probably prefer `https` if `is_secure` is `True`, and `http` if `is_secure` is `False`.

So:
If `protocols` is present:
  - if `is_secure` is `True` and 'https' in `protocols`: `is_secure = True`
  - else if 'http' in `protocols`: `is_secure = False`
  - else if 'https' in `protocols`: `is_secure = True`
  - else: (keep `is_secure` as is)

Actually, if `protocols` is present and `is_secure` is `True`, we only set it to `False` if 'https' is NOT in `protocols`.
If `is_secure` is `False`, we only set it to `True` if 'http' is NOT in `protocols`.

Let's try to reproduce the bug first.

The problem description says:
```python
>>> 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)
```

I can write a reproduction script. Since I don't have a running DynamoDB local, it will probably fail with a connection error, but the key is whether it tries to use `https` or `http`.

If it tries to use `https` on `localhost:8000` and there's nothing there or it's HTTP, it might fail with `SSLError` or `ConnectionError`.

Wait, the error `botocore.vendored.requests.exceptions.SSLError: [SSL: UNKNOWN_PROTOCOL] unknown protocol` happens when you try to do an HTTPS handshake with an HTTP server. This confirms it's using HTTPS.

Let's write a reproduction script that mocks the actual network call or just checks the constructed endpoint URL.

I can mock `botocore.vendored.requests.Session.request` or similar.
But better, I can just use a mock `endpoint_resolver` or just inspect the client's endpoint.

Wait, `create_client` returns a client. The client's endpoint is stored in `client.meta.endpoint`.

Let's try:
```python
import botocore.session
session = botocore.session.get_session()
client = session.create_client('dynamodb', 'local')
print(client.meta.endpoint.url)
```

If the bug exists, this should print `https://localhost:8000/`.
If fixed, it should print `http://localhost:8000/`.

Let's try this.

Ah, it seems I got a different error. `_send_request() takes 5 positional arguments but 6 were given`. This might be because I'm using `create_client` from `botocore.session`, which is not exactly how it's usually used. Usually people use `boto3`.

Wait, the problem says:
```python
>>> import botocore.session
>>> botocore.session.get_session().create_client('dynamodb', 'local').list_tables()
```

Let me check how `botocore.session.Session.create_client` is implemented.

Okay, `create_client` calls `client_creator.create_client`.
`client_creator` is `botocore.client.ClientCreator`.

Let's look at `botocore/client.py`.

I already saw `ClientEndpointBridge.resolve` and `_create_endpoint`.

Wait, I suspect that `botocore.session.get_session().create_client('dynamodb', 'local').list_tables()` failed because `list_tables()` actually tries to send a request, and the `_send_request` in the client might be failing.

If I just want to check the endpoint URL, I can do:

```python
import botocore.session
session = botocore.session.get_session()
client = session.create_client('dynamodb', 'local')
print(client.meta.endpoint.url)
```

Wait, why did it fail with `_send_request() takes 5 positional arguments but 6 were given` when I ran it earlier?

Ah! I see. I ran it as a script. Maybe I should just use `pytest` on a new test file? No, I can't write to `tests/`.

Let's see what `client.meta.endpoint` is.

Wait, I think I know why it failed. I might be using a version of botocore where `Client` is not exactly as I'm calling it.

Let's try this instead:
```python
import botocore.session
session = botocore.session.get_session()
client = session.create_client('dynamodb', 'local')
print(f"Endpoint: {client.meta.endpoint.url}")
```

Let me try to run this again, but I'll be more careful.

Wow, it seems like there's some deep issue with `http/client.py` in the environment, or something. `TypeError: _send_request() takes 5 positional arguments but 6 were given` in `/usr/local/lib/python3.7/http/client.py`. This is very strange.

Wait, I see. `self._send_request(method, url, body, headers, encode_chunked)`. That's 5 arguments. Plus `self`, it's 6.
In Python 3.7, `HTTPConnection._send_request` signature is:
`def _send_request(self, method, url, body, headers, encode_chunked)`

Wait, maybe the environment has some monkey patching going on?

Anyway, I don't need to actually *run* the client if I can just test the `resolve` method of `ClientEndpointBridge`.

Let's try to call `ClientEndpointBridge.resolve` directly.

Wow, it seems like there's some deep issue with `http/client.py` in the environment, or something. `TypeError: _send_request() takes 5 positional arguments but 6 were given` in `/usr/local/lib/python3.7/http/client.py`. This is very strange. Wait, I see. `self._send_request(method, url, body, headers, encode_chunked)`. That's 5 arguments. Plus `self`, it's 6. In Python 3.7, `HTTPConnection._send_request` signature is: `def _send_request(self, method, url, body, headers, encode_chunked)` Wait, maybe the environment has some monkey patching going on? Anyway, I don't need to actually *run* the client if I can just test the `resolve` method of `ClientEndpointBridge`. Let's try to call `ClientEndpointBridge.resolve` directly. <channel|><|tool_call>call:run_command{command:<|"|>python3 - <<'PY' from botocore.client import ClientEndpointBridge from botocore.utils import Registry import json import os # We need to mock the registry to avoid loading all the data class MockRegistry: def __init__(self): self.data = { 'service': { 'dynamodb': { 'endpoint': { 'local': { 'hostname': 'localhost:8000', 'protocols': ['http'] } } } } } def get_endpoint_data(self, service_name, region_name): return self.data['service'][service_name]['endpoint'][region_name] endpoint_bridge = ClientEndpointBridge(MockRegistry()) resolved = endpoint_bridge.resolve('dynamodb', 'local') # resolved is actually a dictionary (the endpoint data) in some versions, # or it might return the result of _create_endpoint # Let's look at resolve() again.
