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.

AttributeError: 'NoneType' object has no attribute 'group'
```
The crash happens in `azurelinuxagent/common/version.py` in `set_current_agent` function.
Specifically, `AGENT_NAME_PATTERN.match(agent)` is returning `None`, and calling `.group(1)` on it causes the `AttributeError`.
The problem occurs when running `waagent` inside `/var/lib/waagent`. This suggests that `set_current_agent()` might be trying to find the agent executable or version by looking at the current working directory or something similar, and it fails when it's inside `/var/lib/waagent`.
Let's examine `azurelinuxagent/common/version.py` and the `set_current_agent` function.

The problematic code is in `set_current_agent`:
```python
def set_current_agent():
path = os.getcwd()
lib_dir = conf.get_lib_dir()
if lib_dir[-1] != os.path.sep:

return agent, FlexibleVersion(version)
```
`conf.get_lib_dir()` probably returns `/usr/lib/python2.7/site-packages` (based on the traceback).
Wait, look at the traceback again:
`File "/usr/lib/python2.7/site-packages/azurelinuxagent/common/version.py", line 85, in set_current_agent`
The user says: "Cannot run any waagent command ... inside the any folder under /var/lib/waagent (such as: /var/lib/waagent/events)".
If `conf.get_lib_dir()` returns something like `/var/lib/waagent`, then `path[:len(lib_dir)] == lib_dir` would be true when `os.getcwd()` is `/var/lib/waagent/events`.
Let's check `azurelinuxagent/common/conf.py` to see what `get_lib_dir()` returns.

Yes, `get_lib_dir` returns `conf.get("Lib.Dir", "/var/lib/waagent")`. So by default it is `/var/lib/waagent`.
Now let's look at `set_current_agent` again:
```python
def set_current_agent():
path = os.getcwd()
lib_dir = conf.get_lib_dir()
if lib_dir[-1] != os.path.sep:
lib_dir += os.path.sep
if path[:len(lib_dir)] != lib_dir:
agent = AGENT_LONG_VERSION
version = AGENT_VERSION
else:
agent = path[len(lib_dir):].split(os.path.sep)[0]
version = AGENT_NAME_PATTERN.match(agent).group(1)
return agent, FlexibleVersion(version)
```
If `os.getcwd()` is `/var/lib/waagent/events`, and `lib_dir` is `/var/lib/waagent/`.
`path[:len(lib_dir)]` will be `/var/lib/waagent/`, which matches `lib_dir`.
Then `agent = path[len(lib_dir):].split(os.path.sep)[0]`.
`path[len(lib_dir):]` is `events`.
`split(os.path.sep)[0]` is `events`.
`AGENT_NAME_PATTERN` is `re.compile("WALinuxAgent-(.*)")`.
`AGENT_NAME_PATTERN.match("events")` returns `None`.
And then `.group(1)` raises the `AttributeError`.
The intention of this code seems to be that if the agent is running from its own installation directory (which might be a subdirectory of `lib_dir` during some update or installation process), it should use the version from the directory name.
Wait, if it's running as a package installed in site-packages, `/var/lib/waagent` is just its data directory, not its code directory.
The logic `if path[:len(lib_dir)] != lib_dir` is trying to detect if we are inside the agent's "lib" directory. But ` Lib.Dir` is typically the data directory, not where the python code lives.
If the user is just `cd`-ing into `/var/lib/waagent/events` and then running `waagent`, they are not running the agent *from* that directory in terms of the python package location, but `os.getcwd()` will indeed be within `/var/lib/waagent`.
The fix should be to ensure that `AGENT_NAME_PATTERN.match(agent)` is not None before calling `.group(1)`. If it's None, it means we are in a subdirectory of `lib_dir` that is not a versioned agent directory, so we should probably fall back to the default `AGENT_LONG_VERSION` and `AGENT_VERSION`.
Let's try to reproduce this.

The reproduction shows that the current code in `/workspace/azurelinuxagent/common/version.py` would crash in Case 2 because it doesn't have the `if match` check.
Wait, if I just add the `if match` check, what should `agent` and `version` be in Case 2?
In the original code, if `path[:len(lib_dir)] != lib_dir`, it uses `AGENT_LONG_VERSION` and `AGENT_VERSION`.
So if `path[:len(lib_dir)] == lib_dir` but the directory name doesn't match the pattern, it should also use `AGENT_LONG_VERSION` and `AGENT_VERSION`.
Let's look at the code again:
```python
if path[:len(lib_dir)] != lib_dir:
agent = AGENT_LONG_VERSION
version = AGENT_VERSION
else:
agent = path[len(lib_dir):].split(os.path.sep)[0]
version = AGENT_NAME_PATTERN.match(agent).group(1)
```
If `path` is `/var/lib/waagent/events` and `lib_dir` is `/var/lib/waagent/`.
`agent` becomes `events`.
`AGENT_NAME_PATTERN.match(agent)` is `None`.
`None.group(1)` crashes.
If we change it to:
```python
if path[:len(lib_dir)] != lib_dir:
agent = AGENT_LONG_VERSION
version = AGENT_VERSION
else:
agent_dir = path[len(lib_dir):].split(os.path.sep)[0]
match = AGENT_NAME_PATTERN.match(agent_dir)
if match:
agent = agent_dir
version = match.group(1)
else:
agent = AGENT_LONG_VERSION
version = AGENT_VERSION
```
Wait, if `agent` is `events`, we should probably just use the defaults.
Actually, if `agent_dir` is not a `WALinuxAgent-*` directory, then we are just in some subdirectory of `/var/lib/waagent`, so we should use the agent version that is actually running (which is `AGENT_VERSION`).
Let's double check if there are other places where this pattern is used.
`AGENT_DIR_PATTERN` is also defined: `AGENT_DIR_PATTERN = re.compile(".*/{0}".format(AGENT_PATTERN))`. But it's not used in `set_current_agent`.
Let's see if there are other occurrences of `set_current_agent` or `AGENT_NAME_PATTERN`.

The tests `TestCurrentAgentName` check for:
1. `test_extract_name_finds_installed`: `os.getcwd()` is outside `lib_dir`.
2. `test_extract_name_finds_latest_agent`: `os.getcwd()` is a `WALinuxAgent-1.2.3` directory inside `lib_dir`.
It doesn't test the case where `os.getcwd()` is a non-versioned directory inside `lib_dir`.
I will implement the fix in `azurelinuxagent/common/version.py`.
```python
def set_current_agent():
path = os.getcwd()
lib_dir = conf.get_lib_dir()
if lib_dir[-1] != os.path.sep:
lib_dir += os.path.sep
if path[:len(lib_dir)] != lib_dir:
agent = AGENT_LONG_VERSION
version = AGENT_VERSION
else:
agent = path[len(lib_dir):].split(os.path.sep)[0]
match = AGENT_NAME_PATTERN.match(agent)
if match:
version = match.group(1)
else:
agent = AGENT_LONG_VERSION
version = AGENT_VERSION
return agent, FlexibleVersion(version)
```
Wait, let's look at the original code again:
```python
else:
agent = path[len(lib_dir):].split(os.path.sep)[0]
version = AGENT_NAME_PATTERN.match(agent).group(1)
```
If `match` is not None, `agent` is already the directory name (e.g., `WALinuxAgent-2.3.0`), and `version` is the extracted version (e.g., `2.3.0`). This is what's returned: `return agent, FlexibleVersion(version)`.
So if `match` is None, we should set `agent = AGENT_LONG_VERSION` and `version = AGENT_VERSION`.
Let's make sure I don't break the "Case 3" from my reproduction.
In Case 3: `path = /var/lib/waagent/WALinuxAgent-2.3.0`, `lib_dir = /var/lib/waagent/`.
`agent` becomes `WALinuxAgent-2.3.0`.
`match = AGENT_NAME_PATTERN.match("WALinuxAgent-2.3.0")` which is not None.
`version` becomes `2.3.0`.
Returns `("WALinuxAgent-2.3.0", FlexibleVersion("2.3.0"))`. Correct.
In Case 2: `path = /var/lib/waagent/events`, `lib_dir = /var/lib/waagent/`.
`agent` becomes `events`.
`match = AGENT_NAME_PATTERN.match("events")` which is None.
We set `agent = AGENT_LONG_VERSION` (`WALinuxAgent-2.2.2`) and `version = AGENT_VERSION` (`2.2.2`).
Returns `("WALinuxAgent-2.2.2", FlexibleVersion("2.2.2"))`. Correct.
One detail: `FlexibleVersion` is used. I should make sure it's imported. It is imported in `version.py`.
Let's refine the `else` block to be concise.
```python
else:
agent = path[len(lib_dir):].split(os.path.sep)[0]
match = AGENT_NAME_PATTERN.match(agent)
if match:
version = match.group(1)
else:
agent = AGENT_LONG_VERSION
version = AGENT_VERSION
```
Wait, what if `path == lib_dir`?
If `path` is `/var/lib/waagent` and `lib_dir` is `/var/lib/waagent/`.
Actually `lib_dir` gets a trailing slash.
`path` is `/var/lib/waagent`. `lib_dir` is `/var/lib/waagent/`.
`path[:len(lib_dir)]` is `/var/lib/waagent`.
Wait, `len(lib_dir)` is 17. `path[:17]` is `/var/lib/waagent`.
`/var/lib/waagent` != `/var/lib/waagent/`.
So it goes to the first `if` block:
`agent = AGENT_LONG_VERSION`
`version = AGENT_VERSION`. Correct.
What if `path` is `/var/lib/waagent/` (with trailing slash) and `lib_dir` is `/var/lib/waagent/`?
Then `path[:len(lib_dir)] == lib_dir`.
`agent = path[len(lib_dir):].split(os.path.sep)[0]`.
`path[len(lib_dir):]` is `""`.
`"".split(os.path.sep)[0]` is `""`.
`AGENT_NAME_PATTERN.match("")` is None.
Our proposed fix would handle this and use defaults.
Let's apply the fix.

The crash happens in `azurelinuxagent/common/version.py` in `set_current_agent` function.
Specifically, `AGENT_NAME_PATTERN.match(agent)` is returning `None`, and calling `.group(1)` on it causes the `AttributeError`.
The problem occurs when running `waagent` inside `/var/lib/waagent`. This suggests that `set_current_agent()` might be trying to find the agent executable or version by looking at the current working directory or something similar, and it fails when it's inside `/var/lib/waagent`.
Let's examine `azurelinuxagent/common/version.py` and the `set_current_agent` function.<|channel>thought

The crash happens in `azurelinuxagent/common/version.py` in `set_current_agent` function.
Specifically, `AGENT_NAME_PATTERN.match(agent)` is returning `None`, and calling `.group(1)` on it causes the `AttributeError`.
The problem occurs when running `waagent` inside `/var/lib/waagent`. This suggests that `set_current_agent()` might be trying to find the agent executable or version by looking at the current working directory or something similar, and it fails when it's inside `/var/lib/waagent`.
Let's examine `azurelinuxagent/common/version.py` and the `set_current_agent` function.<channel|><|tool_call>call:read_file{filepath:<|"|>azurelinuxagent/common/version.py<|"|>,start_line:60}<tool_call|><|tool_response>

Yes, `get_lib_dir` returns `conf.get("Lib.Dir", "/var/lib/waagent")`. So by default it is `/var/lib/waagent`.
Now let's look at `set_current_agent` again:
```python
def set_current_agent():
path = os.getcwd()
lib_dir = conf.get_lib_dir()
if lib_dir[-1] != os.path.sep:
lib_dir += os.path.sep
if path[:len(lib_dir)] != lib_dir:
agent = AGENT_LONG_VERSION
version = AGENT_VERSION
else:
agent = path[len(lib_dir):].split(os.path.sep)[0]
version = AGENT_NAME_PATTERN.match(agent).group(1)
return agent, FlexibleVersion(version)
```
If `os.getcwd()` is `/var/lib/waagent/events`, and `lib_dir` is `/var/lib/waagent/`.
`path[:len(lib_dir)]` will be `/var/lib/waagent/`, which matches `lib_dir`.
Then `agent = path[len(lib_dir):].split(os.path.sep)[0]`.
`path[len(lib_dir):]` is `events`.
`split(os.path.sep)[0]` is `events`.
`AGENT_NAME_PATTERN` is `re.compile("WALinuxAgent-(.*)")`.
`AGENT_NAME_PATTERN.match("events")` returns `None`.
And then `.group(1)` raises the `AttributeError`.
The intention of this code seems to be that if the agent is running from its own installation directory (which might be a subdirectory of `lib_dir` during some update or installation process), it should use the version from the directory name.
Wait, if it's running as a package installed in site-packages, `/var/lib/waagent` is just its data directory, not its code directory.
The logic `if path[:len(lib_dir)] != lib_dir` is trying to detect if we are inside the agent's "lib" directory. But ` Lib.Dir` is typically the data directory, not where the python code lives.
If the user is just `cd`-ing into `/var/lib/waagent/events` and then running `waagent`, they are not running the agent *from* that directory in terms of the python package location, but `os.getcwd()` will indeed be within `/var/lib/waagent`.
The fix should be to ensure that `AGENT_NAME_PATTERN.match(agent)` is not None before calling `.group(1)`. If it's None, it means we are in a subdirectory of `lib_dir` that is not a versioned agent directory, so we should probably fall back to the default `AGENT_LONG_VERSION` and `AGENT_VERSION`.
Let's try to reproduce this.Yes, `get_lib_dir` returns `conf.get("Lib.Dir", "/var/lib/waagent")`. So by default it is `/var/lib/waagent`.
Now let's look at `set_current_agent` again:
```python
def set_current_agent():
path = os.getcwd()
lib_dir = conf.get_lib_dir()
if lib_dir[-1] != os.path.sep:
lib_dir += os.path.sep
if path[:len(lib_dir)] != lib_dir:
agent = AGENT_LONG_VERSION
version = AGENT_VERSION
else:
agent = path[len(lib_dir):].split(os.path.sep)[0]
version = AGENT_NAME_PATTERN.match(agent).group(1)
return agent, FlexibleVersion(version)
```
If `os.getcwd()` is `/var/lib/waagent/events`, and `lib_dir` is `/var/lib/waagent/`.
`path[:len(lib_dir)]` will be `/var/lib/waagent/`, which matches `lib_dir`.
Then `agent = path[len(lib_dir):].split(os.path.sep)[0]`.
`path[len(lib_dir):]` is `events`.
`split(os.path.sep)[0]` is `events`.
`AGENT_NAME_PATTERN` is `re.compile("WALinuxAgent-(.*)")`.
`AGENT_NAME_PATTERN.match("events")` returns `None`.

The reproduction shows that the current code in `/workspace/azurelinuxagent/common/version.py` would crash in Case 2 because it doesn't have the `if match` check.
Wait, if I just add the `if match` check, what should `agent` and `version` be in Case 2?
In the original code, if `path[:len(lib_dir)] != lib_dir`, it uses `AGENT_LONG_VERSION` and `AGENT_VERSION`.
So if `path[:len(lib_dir)] == lib_dir` but the directory name doesn't match the pattern, it should also use `AGENT_LONG_VERSION` and `AGENT_VERSION`.
Let's look at the code again:
```python
if path[:len(lib_dir)] != lib_dir:
agent = AGENT_LONG_VERSION
version = AGENT_VERSION
else:
agent = path[len(lib_dir):].split(os.path.sep)[0]
version = AGENT_NAME_PATTERN.match(agent).group(1)
```
If `path` is `/var/lib/waagent/events` and `lib_dir` is `/var/lib/waagent/`.
`agent` becomes `events`.
`AGENT_NAME_PATTERN.match(agent)` is `None`.

Wait, if `agent` is `events`, we should probably just use the defaults.
Actually, if `agent_dir` is not a `WALinuxAgent-*` directory, then we are just in some subdirectory of `/var/lib/waagent`, so we should use the agent version that is actually running (which is `AGENT_VERSION`).
Let's double check if there are other places where this pattern is used.
`AGENT_DIR_PATTERN` is also defined: `AGENT_DIR_PATTERN = re.compile(".*/{0}".format(AGENT_PATTERN))`. But it's not used in `set_current_agent`.

2. `test_extract_name_finds_latest_agent`: `os.getcwd()` is a `WALinuxAgent-1.2.3` directory inside `lib_dir`.
It doesn't test the case where `os.getcwd()` is a non-versioned directory inside `lib_dir`.
I will implement the fix in `azurelinuxagent/common/version.py`.
```python
def set_current_agent():

If `match` is not None, `agent` is already the directory name (e.g., `WALinuxAgent-2.3.0`), and `version` is the extracted version (e.g., `2.3.0`). This is what's returned: `return agent, FlexibleVersion(version)`.
So if `match` is None, we should set `agent = AGENT_LONG_VERSION` and `version = AGENT_VERSION`.
Let's make sure I don't break the "Case 3" from my reproduction.
In Case 3: `path = /var/lib/waagent/WALinuxAgent-2.3.0`, `lib_dir = /var/lib/waagent/`.
`agent` becomes `WALinuxAgent-2.3.0`.
`match = AGENT_NAME_PATTERN.match("WALinuxAgent-2.3.0")` which is not None.
`version` becomes `2.3.0`.
Returns `("WALinuxAgent-2.3.0", FlexibleVersion("2.3.0"))`. Correct.
In Case 2: `path = /var/lib/waagent/events`, `lib_dir = /var/lib/waagent/`.
`agent` becomes `events`.
`match = AGENT_NAME_PATTERN.match("events")` which is None.
We set `agent = AGENT_LONG_VERSION` (`WALinuxAgent-2.2.2`) and `version = AGENT_VERSION` (`2.2.2`).
Returns `("WALinuxAgent-2.2.2", FlexibleVersion("2.2.2"))`. Correct.
One detail: `FlexibleVersion` is used. I should make sure it's imported. It is imported in `version.py`.
Let's refine the `else` block to be concise.
```python

Actually `lib_dir` gets a trailing slash.
`path` is `/var/lib/waagent`. `lib_dir` is `/var/lib/waagent/`.
`path[:len(lib_dir)]` is `/var/lib/waagent`.
Wait, `len(lib_dir)` is 17. `path[:17]` is `/var/lib/waagent`.
`/var/lib/waagent` != `/var/lib/waagent/`.
So it goes to the first `if` block:
`agent = AGENT_LONG_VERSION`
`version = AGENT_VERSION`. Correct.
