# Combo Lock

The combo-lock is a combination of a process lock and a thread lock. Usable in cases both multiple threads and multiple processes are sharing the same resource such as a file in the file system.

The module utilizes the FileLock from [filelock](https://pypi.org/project/filelock/) and the standard *Lock* from threading.

The FileLock uses a filesystem lock so the initialization of the class requires a path for the lock file.

## Example

```python
from combo_lock import ComboLock

lock = ComboLock('/tmp/my.lock')

with lock:
    write_my_shared_resource()


```

A `NamedLock` will save the lock file to shared memory using [memory-tempfile](https://github.com/mbello/memory-tempfile)

```python
from combo_lock import NamedLock

lock = NamedLock('some_name')

with lock:
    write_my_shared_resource()
```

### History

The combo-lock was originally created for [Mycroft-core](https://github.com/mycroftai/mycroft-core) but as it's been useful in other projects a separate release seemed appropriate.

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.
