A basic example demonstrating how to use smmap to memory-map a file and read data from it.

import os from smmap import MemoryMap # Initialize a MemoryMap instance mm = MemoryMap('example.txt') # Read data from the memory-mapped file with mm as m: data = m.read(1024) print(data)

Known issues

breakingVersion 6.0.0 dropped support for Python 3.6 and 3.7, and declared support for Python 3.11 and 3.12.

fix

Upgrade to Python 3.11 or later.

affects: >=6.0.0

deprecatedVersion 5.0.0 dropped support for Python 3.5.

fix

Upgrade to Python 3.6 or later.

affects: >=5.0.0

gotchaEnsure that the smmap package is installed in the correct Python environment to avoid ImportError.

fix

Use pip to install smmap in the active environment.

affects: All

breakingThe 'MemoryMap' class was removed from the top-level 'smmap' module in version 5.0.0. For smmap versions 5.x, it was moved to 'smmap.mman'. In version 6.0.0 and later, 'MemoryMap' was entirely removed.

fix

If using smmap 5.x, update imports from `from smmap import MemoryMap` to `from smmap.mman import MemoryMap`. If using smmap 6.0.0 or later, 'MemoryMap' is no longer available, and an alternative implementation or library version is required.

affects: >=5.0.0

breakingThe 'MemoryMap' class/symbol was removed from the 'smmap' library in version 0.3.0. Applications attempting to import 'MemoryMap' directly from 'smmap' will fail.

fix

Downgrade smmap to a version older than 0.3.0 (e.g., `pip install smmap<0.3.0`) or update your application code to remove the dependency on 'smmap.MemoryMap'.

affects: >=0.3.0
