# Readers / writers file lock Python helper class

[![Test PyPI Deployment](https://github.com/inab/RWFileLock/actions/workflows/build_n_deploy.yml/badge.svg)](https://github.com/inab/RWFileLock/actions/workflows/build_n_deploy.yml)

This library was created in order to ease the synchronization of several processes

using shared resources, like a caching directory or a SQLite database. All of them

can use the resources, but only one should update them.

The library is being used in several INB projects.

## Example of a shared lock using context:

```python

import datetime

import os

import time

from RWFileLock import RWFileLock

lock = RWFileLock("/tmp/rwfilelock.lock")

with lock.shared_lock():

    print(

        f"[{datetime.datetime.now().isoformat()}] Got shlock {os.getpid()}"

    )

	

    time.sleep(7)

    print(

        f"[{datetime.datetime.now().isoformat()}] Releasing shlock {os.getpid()}"

    )

```
