How to solve newly created directories not visible on another process in Python
If you have created a new directory in Python but it is not immediately visible to another process, it could be due to caching or delayed synchronization of the file system. To address this issue, you can try the following solutions:
Flush the file system cache: In Python, you can use the
os.fsync()
function to flush the file system cache and ensure that the directory creation is immediately visible to other processes. Here's an example:pythonimport os
# Create a new directory
os.mkdir("path/to/new_directory")
# Flush the file system cache
os.fsync(os.open("path/to/new_directory", os.O_RDONLY))
This code creates a new directory and then uses
os.fsync()
to flush the file system cache for that directory. This can help ensure that other processes can immediately see the newly created directory.Sleep for a short duration: If flushing the file system cache doesn't work, you can introduce a short delay using the
time.sleep()
function to allow the file system to synchronize. Here's an example:pythonimport os
import time
# Create a new directory
os.mkdir("path/to/new_directory")
# Sleep for a short duration
time.sleep(0.1) # Adjust the sleep duration as needed
By sleeping for a short duration, you give the file system time to synchronize and make the newly created directory visible to other processes.
Try implementing one of these solutions after creating a new directory in Python. However, keep in mind that file system behavior can vary across different platforms and operating systems.
