This pull request improves file handling in the download_file
function to ensure better resource management.
The download_file
function in himatpy/tools/snow_download_by_tile.py
was updated to use a with
statement when opening files. This change ensures that files are automatically closed after the block of code within the with
statement is executed, reducing the risk of file descriptor leaks.
Specifically, the line f = open(filepath, 'wb')
was replaced with with open(filepath, 'wb') as f:
. Additionally, the file writing operation f.write(data.read())
was moved inside the with
block to maintain the functionality of writing data to the file while it is open.
I'm confident in this change, but I'm not a maintainer of this project. Do you see any reason not to merge it?
If this change was not helpful, or you have suggestions for improvements, please let me know!
Just a friendly ping to remind you about this change. If there are concerns about it, we'd love to hear about them!
This change may not be a priority right now, so I'll close it. If there was something I could have done better, please let me know!
You can also customize me to make sure I'm working with you in the way you want.
This codemod wraps assignments of
open
calls in a with statement. Without explicit closing, these resources will be "leaked" and won't be re-claimed until garbage collection. In situations where these resources are leaked rapidly (either through malicious repetitive action or unusually spiky usage), connection pool or file handle exhaustion will occur. These types of failures tend to be catastrophic, resulting in downtime and many times affect downstream applications.Our changes look something like this:
