Bug Report
Description
When an exception is raised during a file operation, the file handle may not be properly closed, leading to a resource leak.
Steps to Reproduce
- Open a file without using a context manager
- Raise an exception before closing the file
- The file handle remains open
Expected Behavior
File handles should always be closed, even when exceptions occur.
Suggested Fix
Use a with statement (context manager) to ensure the file is always closed:
# Instead of:
f = open('file.txt', 'r')
data = f.read()
f.close()
# Use:
with open('file.txt', 'r') as f:
data = f.read()
Environment
- Python 3.x
- Any OS
This is a common Python pitfall that can cause issues in long-running applications.

Research direction
No repository file or failing test is identified. Start by locating the affected file operation in the Sentry codebase and reproduce the exception path described. Done means the handle is closed when the operation raises and a regression test covers it.
