Temporary files and directories.
Contains replacement for tempfile.NamedTemporaryFile that does not delete
the file on close(), but still unlinks it after the context manager ends,
as well as a mkdtemp-based temporary directory implementation.
- Mostly reuses the stdlib implementations, supporting the same signatures.
- Due to that, uses the OS's built-in temporary file facilities, no custom schemes.
- Tested on Python 2.6 and 3.3
A typical use-case that is not possible with the regular
NamedTemporaryFile:
import volatile
with volatile.file() as tmp:
# tmp behaves like a regular NamedTemporaryFile here, except for that
# it gets unlinked at the end of the context manager, instead of when
# close() is called.
tmp.close()
# run the users $EDITOR
run_editor(tmp.name)
buf = open(tmp.name).read()
# ...Temporary directories:
import volatile
with volatile.dir(): as dtmp:
pass # ... can use directory here
# a missing dtmp will not throw an exception!Unix domain sockets:
import volatile
with volatile.unix_socket(): as (sock, addr):
# sock is the bound socket, addr its address on the filesystem
pass # ... can use directory hereThe source is fairly short and contains API docs in the comments.
