asynctempfile

asynctempfile

Async interface for the standard tempfile module. Implements the following 4 classes:

• TemporaryFile
• NamedTemporaryFile
• SpooledTemporaryFile
• TemporaryDirectory

Blocking methods are delegated to threadpools using loop.run_in_executor(). Non-blocking methods and properties retain a sync interface. SpooledTemporaryFile only delegates if the in-memory stream is rolled to disk. New instances of the above classes return wrapped with a context manager allowing use with async with and async for.

Installation

pip install asynctempfile

    async for line in f:
        print(line)

Release Notes

0.5.0

• Adjusted TemporaryDirectory to return its path as opposed to the object when used with a context manager, aligning behaviour with the sync library (thank you to hellocoldworld).
• Fixed name attribute for TemporaryFile as this property is now included in the aiofiles wrapper.
