13.8.1. File Locking

Try these first

1. 1.

   What is the purpose of file locking?

   Hint

   Think about data integrity.

2. 2.

   Which module is used for file locking in Python on Unix-like systems?

   Hint

   It starts with an 'f' and is used in Unix.

3. 3.

   What is file locking primarily used for?

   • To speed up file access
   • To prevent race conditions
   • To encrypt files

   Hint

   Think about what happens if two programs access the file at the same time.

4. 4.

   True or False: Exclusive locks allow more than one process to write to a file at the same time.

   • True
   • False

   Hint

   Consider what happens when two processes try to write to a file.

5. 5.

   Design a multi-threaded application that writes to a shared log file without causing race conditions. Implement file locking accordingly.

   Hint

   Think about how locks help in data integrity.

6. 6.

   Create a situation where file locking fails. Describe how your application could handle this gracefully.

   Hint

   Consider using exponential backoff for retries.
