74-74: Update function docstring to reflect the return type change.The return type has been changed from
Tuple[bool, str, str]toTuple[bool, Any, Any], but the docstring still implies string returns. Please update the docstring to accurately reflect that the second and third elements can be of any type.Returns: - tuple: True, out if command succeeded, False, err otherwise. + tuple: (success: bool, out: Any, err: Any) where 'success' indicates if command succeeded, + 'out' contains raw stdout, and 'err' contains raw stderr.webhook_server_container/libs/github_api.py (3)
2019-2021: Ensure consistent output handling with explicit type checks.The current implementation assumes that
_outand_errcan be either bytes or str. While this works, it could be more robust with explicit type checks and error handling.Consider this more defensive implementation:
- rc, _out, _err = run_command(command=command, log_prefix=self.log_prefix, pipe=pipe) - out = _out.decode() if isinstance(_out, bytes) else _out - err = _err.decode() if isinstance(_err, bytes) else _err + rc, _out, _err = run_command(command=command, log_prefix=self.log_prefix, pipe=pipe) + try: + out = _out.decode('utf-8') if isinstance(_out, bytes) else str(_out) + err = _err.decode('utf-8') if isinstance(_err, bytes) else str(_err) + except UnicodeDecodeError as e: + self.logger.error(f"{self.log_prefix} Failed to decode command output: {e}") + return False, str(_out), str(_err)This change:
- Explicitly specifies UTF-8 encoding for consistency
- Handles potential decode errors gracefully
- Ensures string type for outputs even if decode fails

2018-2031: Improve error handling and prevent potential infinite recursion.The method's error handling and bug fix logic could be enhanced for better reliability.
Consider these improvements:
def run_podman_command(self, command: str, pipe: bool = False) -> Tuple[bool, str, str]: + max_retries = 1 + attempt = 0 + + while attempt <= max_retries: + try: rc, _out, _err = run_command(command=command, log_prefix=self.log_prefix, pipe=pipe) out = _out.decode('utf-8') if isinstance(_out, bytes) else str(_out) err = _err.decode('utf-8') if isinstance(_err, bytes) else str(_err) if rc: return rc, out, err if self.is_podman_bug(err=err): + if attempt == max_retries: + self.logger.error(f"{self.log_prefix} Max retries reached for Podman bug fix") + return rc, out, err + self.fix_podman_bug() - return run_command(command=command, log_prefix=self.log_prefix, pipe=pipe) + attempt += 1 + continue return rc, out, err + except Exception as e: + self.logger.error(f"{self.log_prefix} Failed to run Podman command: {e}") + return False, "", str(e)This change:
- Adds a retry limit to prevent infinite recursion
- Wraps the command execution in a try-except block
- Improves error logging
- Returns meaningful error messages on exceptions

2014-2017: Enhance Podman bug fix safety and verification.The current bug fix implementation could be safer and more verifiable.
Consider these improvements:
def fix_podman_bug(self) -> None: self.logger.debug(f"{self.log_prefix} Fixing podman bug") - shutil.rmtree("/tmp/storage-run-1000/containers", ignore_errors=True) - shutil.rmtree("/tmp/storage-run-1000/libpod/tmp", ignore_errors=True) + paths = [ + "/tmp/storage-run-1000/containers", + "/tmp/storage-run-1000/libpod/tmp" + ] + + for path in paths: + try: + if os.path.exists(path): + # Create a backup with timestamp + backup_path = f"{path}.bak.{int(time.time())}" + shutil.move(path, backup_path) + self.logger.debug(f"{self.log_prefix} Created backup at {backup_path}") + + # Recreate empty directory + os.makedirs(path, exist_ok=True) + self.logger.debug(f"{self.log_prefix} Recreated directory {path}") + except OSError as e: + self.logger.error(f"{self.log_prefix} Failed to fix Podman bug for {path}: {e}")This change:
- Creates backups before deletion
- Handles each path separately
- Improves error logging
- Recreates directories after cleanup

114-115: Verify impact on downstream code.
The change to return raw subprocess output without decoding is good as it provides more flexibility and avoids potential encoding issues. However, we should verify that downstream code can handle non-decoded output.
✅ Verification successful
Let me analyze the code further to check how the output is being used.
Change is safe - output decoding is handled by callers
The change to return raw subprocess output is safe because:
- The main caller in
github_api.pyexplicitly handles decoding without = _out.decode() if isinstance(_out, bytes) else _out - All other usages only pass the output to logging functions or error handlers that can handle both decoded and raw output
- No direct string operations are performed on the raw output without proper decoding first
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Search for direct string operations on the command output
# that might break with non-decoded output
# Find usages of run_command where the output is used with string operations
rg -l 'run_command.*' | xargs rg '\b(out|err)_decoded\b.*\.(strip|split|replace|format|join|encode|decode)'
# Find all callers of run_command to manually verify their output handling
ast-grep --pattern 'run_command($$$)'
Length of output: 4035
Script:
#!/bin/bash
# Check how the output from run_command is used in github_api.py
rg -A 5 'rc, .*out.*, .*err.* = run_command' webhook_server_container/libs/github_api.py
# Also check the implementation of run_command to see if there's any output processing
rg -A 10 'def run_command' webhook_server_container/utils/helpers.py
