reconnecting-ftp 1.0.8

Reconnecting FTP client

reonnecting_ftp

reconnecting_ftp provides a FTP client which wraps ftplib.FTP. It reconnects automatically to the server if it was disconnected, and remembers the last recorded working directory.

We found reconnection to be particularly important in scripts which run for a long time, and need to repeatedly iterate over the files on the FTP server.

Additionally, we provide an implementation of mlst FTP command which is missing in the original ftplib.FTP client.

Usage

import reconnecting_ftp

with reconnecting_ftp.Client(hostname="some-host.com", port=21, user="some-user", password="some-password") as ftp:
    # change working directory
    ftp.cwd(dirname='/some-dir/some-subdir')

    # you can execute here all the commands as provided in ftplib.FTP. If the connection failed, the command will
    # be retried while it succeeds or the maximum number of retries haven been exhausted..

    # MLST the file
    pth, entry = ftp.mlst(filename='some-file.txt')

Installation

• Create a virtual environment:

python3 -m venv venv3

• Activate it:

source venv3/bin/activate

• Install reconnecting_ftp with pip:

pip3 install reconnecting_ftp

Development

• Check out the repository.

• In the repository root, create the virtual environment:

python3 -m venv venv3

• Activate the virtual environment:

source venv3/bin/activate

• Install the development dependencies:

pip3 install -e .[dev]

• We provide a set of pre-commit checks that lint and check code for formatting and runs unit tests. Run them locally from an activated virtual environment with development dependencies:

./precommit.py

• The pre-commit script can also automatically format the code:

./precommit.py  --overwrite
