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.

The `convert_entity` function is inside `replace_entities` (although the `replace_entities` definition is before line 50). The `convert_entity` function handles decimal, hex, and named entities. It converts them to a codepoint `number`. Then it uses `chr(number)` to convert the codepoint to a character. If `number` is too large, `chr(number)` can raise `ValueError` (Python 3) or `OverflowError` on some platforms/versions if it's really huge, although in Python 3 `chr()` usually raises `ValueError` for codepoints outside the Unicode range (0 to 0x10FFFF). Wait, the issue report says `OverflowError: Python int too large to convert to C int`. This often happens when passing a very large integer to a C function. `chr()` in Python 3 raises `ValueError` if the integer is outside the range `0 <= x <= 0x10FFFF`. Let's check what `chr()` does with a very large number in Python 3.8.

Aha! On this environment (Python 3.8.13), `chr(10**20)` indeed raises `OverflowError`.
The current code has:
```python
try:
if 0x80 <= number <= 0x9F:
return bytes((number,)).decode("cp1252")
else:
return chr(number)
except ValueError:
pass
```
It only catches `ValueError`. It needs to catch `OverflowError` as well.
Let's double check the `replace_entities` function to see if it's used as suspected.

Reproduction successful. Now I need to fix it by adding `OverflowError` to the `except` block. I should check if there are other places where `convert_entity` or similar logic is used in `w3lib/html.py`. Looking at `w3lib/html.py`: I see `replace_entities` which uses `convert_entity`.

Only used once in `replace_entities`.
Wait, the `convert_entity` function is defined *inside* `replace_entities`.
Let's review the code again.
```python
def convert_entity(m: Match) -> str:
# ...
if number is not None:
# ...
try:
if 0x80 <= number <= 0x9F:
return bytes((number,)).decode("cp1252")
else:

except ValueError:

return "" if remove_illegal and groups.get("semicolon") else m.group(0)
```
I will change `except ValueError:` to `except (ValueError, OverflowError):`.
Wait, I should check if `bytes((number,))` can also raise `OverflowError`.

`bytes((number,))` raises `ValueError` if the number is not in `range(0, 256)`. But `number` is already checked with `if 0x80 <= number <= 0x9F:`, so it will always be in `range(0, 256)`. However, it's better to be safe. The main issue is `chr(number)`. Let's apply the fix.

Existing tests passed.
I'll just do one more check on `w3lib/html.py` to see if there are any other symbols that might be affected. The `convert_entity` is nested inside `replace_entities`, so it's reasonably isolated.
Let's double check the code again.
```python
def convert_entity(m: Match) -> str:
groups = m.groupdict()
number = None
if groups.get("dec"):
number = int(groups["dec"], 10)
elif groups.get("hex"):
number = int(groups["hex"], 16)
elif groups.get("named"):
# ...
if number is not None:
try:
if 0x80 <= number <= 0x9F:
return bytes((number,)).decode("cp1252")
else:
return chr(number)
except (ValueError, OverflowError):
pass
return "" if remove_illegal and groups.get("semicolon") else m.group(0)
```
If `number` is too large and `chr(number)` raises `OverflowError`, it now catches it and falls through to `return "" if remove_illegal and groups.get("semicolon") else m.group(0)`. This is the correct behavior for an "illegal" entity.
One more check: what if `int(groups["dec"], 10)` itself raises an `OverflowError`?
In Python 3, `int()` with a string does not raise `OverflowError` as integers have arbitrary precision. It will only raise `ValueError` if the string is not a valid integer.
Example:
TOOL CALL · run_command
{
"command": "python3 - <<'PY'\ntry:\n int(\"1\" * 1000000, 10)\n print(\"Success\")\nexcept Exception as e:\n print(type(e), e)\nPY\n"

}Turn 13at 168 s258 tokens out6,750 prompt tokens
It raises `ValueError` because of the `sys.set_int_max_str_digits` limit introduced in recent Python versions to prevent DoS attacks. This `ValueError` would not be caught because it happens before the `try...except` block.
However, the issue report specifically mentioned `OverflowError: Python int too large to convert to C int` which happens in `chr()`.
Let's check if any other part of the `convert_entity` function can raise `OverflowError`.
`bytes((number,)).decode("cp1252")`: `number` is already checked to be between 0x80 and 0x9F.
`name2codepoint.get(entity_name)`: just a dictionary lookup.
Wait, let's check if `int(groups["hex"], 16)` can raise `OverflowError`.

Actually, `int()` for hex doesn't seem to have the same limit as decimal in some Python versions, or it just worked. Wait, the output says "Success". Actually, `sys.set_int_max_str_digits` applies to all bases except 0. Let me check the Python version again. It's 3.8.13. `sys.set_int_max_str_digits` was added in 3.10.7, 3.9.14, 3.8.14, and 3.7.14. The environment is 3.8.13, so it might not have that limit. Regardless, the issue was specifically about `OverflowError` coming from `chr()`. I have reproduced the bug, fixed it, and verified it both with a script and existing tests. Final check of the diff:

The `convert_entity` inner function in `w3lib.html.replace_entities` was catching `ValueError` when calling `chr()`, but on some Python versions (like 3.8.13), passing an extremely large integer to `chr()` can raise an `OverflowError` ("Python int too large to convert to C int"). I updated the `except` block to catch both `ValueError` and `OverflowError`, ensuring that oversized numeric entities are handled gracefully according to the `remove_illegal` flag.

It converts them to a codepoint `number`. Then it uses `chr(number)` to convert the codepoint to a character. If `number` is too large, `chr(number)` can raise `ValueError` (Python 3) or `OverflowError` on some platforms/versions if it's really huge, although in Python 3 `chr()` usually raises `ValueError` for codepoints outside the Unicode range (0 to 0x10FFFF). Wait, the issue report says `OverflowError: Python int too large to convert to C int`. This often happens when passing a very large integer to a C function. `chr()` in Python 3 raises `ValueError` if the integer is outside the range `0 <= x <= 0x10FFFF`. Let's check what `chr()` does with a very large number in Python 3.8.

Aha! On this environment (Python 3.8.13), `chr(10**20)` indeed raises `OverflowError`.
The current code has:
```python
try:
if 0x80 <= number <= 0x9F:
return bytes((number,)).decode("cp1252")
else:
return chr(number)
except ValueError:
pass
```
It only catches `ValueError`. It needs to catch `OverflowError` as well.
Let's double check the `replace_entities` function to see if it's used as suspected.

Reproduction successful. Now I need to fix it by adding `OverflowError` to the `except` block. I should check if there are other places where `convert_entity` or similar logic is used in `w3lib/html.py`. Looking at `w3lib/html.py`: I see `replace_entities` which uses `convert_entity`. Let's see if there are other functions that might use this logic.

`bytes((number,))` raises `ValueError` if the number is not in `range(0, 256)`. But `number` is already checked with `if 0x80 <= number <= 0x9F:`, so it will always be in `range(0, 256)`. However, it's better to be safe. The main issue is `chr(number)`. Let's apply the fix.

Existing tests passed.
I'll just do one more check on `w3lib/html.py` to see if there are any other symbols that might be affected. The `convert_entity` is nested inside `replace_entities`, so it's reasonably isolated.
Let's double check the code again.
```python
def convert_entity(m: Match) -> str:
groups = m.groupdict()
number = None
if groups.get("dec"):
number = int(groups["dec"], 10)
elif groups.get("hex"):
number = int(groups["hex"], 16)
elif groups.get("named"):
# ...
if number is not None:
try:
if 0x80 <= number <= 0x9F:
return bytes((number,)).decode("cp1252")
else:
return chr(number)
except (ValueError, OverflowError):
pass
return "" if remove_illegal and groups.get("semicolon") else m.group(0)
```
If `number` is too large and `chr(number)` raises `OverflowError`, it now catches it and falls through to `return "" if remove_illegal and groups.get("semicolon") else m.group(0)`. This is the correct behavior for an "illegal" entity.
One more check: what if `int(groups["dec"], 10)` itself raises an `OverflowError`?
In Python 3, `int()` with a string does not raise `OverflowError` as integers have arbitrary precision. It will only raise `ValueError` if the string is not a valid integer.

It raises `ValueError` because of the `sys.set_int_max_str_digits` limit introduced in recent Python versions to prevent DoS attacks. This `ValueError` would not be caught because it happens before the `try...except` block.

Actually, `int()` for hex doesn't seem to have the same limit as decimal in some Python versions, or it just worked. Wait, the output says "Success". Actually, `sys.set_int_max_str_digits` applies to all bases except 0. Let me check the Python version again. It's 3.8.13. `sys.set_int_max_str_digits` was added in 3.10.7, 3.9.14, 3.8.14, and 3.7.14. The environment is 3.8.13, so it might not have that limit. Regardless, the issue was specifically about `OverflowError` coming from `chr()`.
