⇆🎉 copyparty

• http file sharing hub (py2/py3) (on PyPI)
• MIT-Licensed, 2019-05-26, ed @ irc.rizon.net

summary

turn your phone or raspi into a portable file server with resumable uploads/downloads using IE6 or any other browser

• server runs on anything with py2.7 or py3.2+
• resumable uploads need firefox 12+ / chrome 6+ / safari 6+ / IE 10+
• code standard: black

quickstart

download copyparty-sfx.py and you're all set!

running the sfx without arguments (for example doubleclicking it on Windows) will let anyone access the current folder; see -h for help if you want accounts and volumes etc

you may also want these, especially on servers:

• contrib/systemd/copyparty.service to run copyparty as a systemd service
• contrib/nginx/copyparty.conf to reverse-proxy behind nginx (for legit https)

notes

• iPhone/iPad: use Firefox to download files
• Android-Chrome: set max "parallel uploads" for 200% upload speed (android bug)
• Android-Firefox: takes a while to select files (in order to avoid the above android-chrome issue)
• Desktop-Firefox: may use gigabytes of RAM if your connection is great and your files are massive
• paper-printing is affected by dark/light-mode! use lightmode for color, darkmode for grayscale
  • because no browsers currently implement the media-query to do this properly orz

status

• sanic multipart parser
• load balancer (multiprocessing)
• upload (plain multipart, ie6 support)
• upload (js, resumable, multithreaded)
• download
• browser
• media player
• thumbnails
• download as zip
• volumes
• accounts
• markdown viewer
• markdown editor
• FUSE client (read-only)

summary: it works! you can use it! (but technically not even close to beta)

client examples

• javascript: dump some state into a file (two separate examples)

  • await fetch('https://127.0.0.1:3923/', {method:"PUT", body: JSON.stringify(foo)});
  • var xhr = new XMLHttpRequest(); xhr.open('POST', 'https://127.0.0.1:3923/msgs?raw'); xhr.send('foo');

• FUSE: mount a copyparty server as a local filesystem

  • cross-platform python client available in ./bin/
  • rclone as client can give ~5x performance, see ./docs/rclone.md

dependencies

• jinja2
  • pulls in markupsafe as of v2.7; use jinja 2.6 on py3.2

optional, enables thumbnails:

• Pillow (requires py2.7 or py3.5+)

sfx

currently there are two self-contained binaries:

• copyparty-sfx.sh for unix (linux and osx) -- smaller, more robust
• copyparty-sfx.py for windows (unix too) -- crossplatform, beta

launch either of them (use sfx.py on systemd) and it'll unpack and run copyparty, assuming you have python installed of course

pls note that copyparty-sfx.sh will fail if you rename copyparty-sfx.py to copyparty.py and keep it in the same folder because sys.path is funky

sfx repack

if you don't need all the features you can repack the sfx and save a bunch of space; all you need is an sfx and a copy of this repo (nothing else to download or build, except for either msys2 or WSL if you're on windows)

• 724K original size as of v0.4.0
• 256K after ./scripts/make-sfx.sh re no-ogv
• 164K after ./scripts/make-sfx.sh re no-ogv no-cm

the features you can opt to drop are

• ogv.js, the opus/vorbis decoder which is needed by apple devices to play foss audio files
• cm/easymde, the "fancy" markdown editor

for the repack to work, first run one of the sfx'es once to unpack it

note: you can also just download and run scripts/copyparty-repack.sh -- this will grab the latest copyparty release from github and do a no-ogv no-cm repack; works on linux/macos (and windows with msys2 or WSL)

install on android

install Termux (see ocv.me/termux) and then copy-paste this into Termux (long-tap) all at once:

apt update && apt -y full-upgrade && termux-setup-storage && apt -y install python && python -m ensurepip && python -m pip install -U copyparty
echo $?

after the initial setup, you can launch copyparty at any time by running copyparty anywhere in Termux

dev env setup

python3 -m venv .venv
. .venv/bin/activate
pip install jinja2  # mandatory deps
pip install Pillow  # thumbnail deps
pip install black bandit pylint flake8  # vscode tooling

how to release

in the scripts folder:

• run make -C deps-docker to build all dependencies
• create github release with make-tgz-release.sh
• upload to pypi with make-pypi-release.(sh|bat)
• create sfx with make-sfx.sh

todo

roughly sorted by priority

• reduce up2k roundtrips
  • start from a chunk index and just go
  • terminate client on bad data
• drop onto folders
• os.copy_file_range for up2k cloning
• up2k partials ui
• support pillow-simd
• cache sha512 chunks on client
• comment field
• look into android thumbnail cache file format bad idea
• figure out the deal with pixel3a not being connectable as hotspot
  • pixel3a having unpredictable 3sec latency in general :||||
