⇆🎉 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 py3.3+
• 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

• backend stuff
  • ☑ sanic multipart parser
  • ☑ load balancer (multiprocessing)
  • ☑ volumes (mountpoints)
  • ☑ accounts
• upload
  • ☑ basic: plain multipart, ie6 support
  • ☑ up2k: js, resumable, multithreaded
  • ☑ stash: simple PUT filedropper
  • ☑ symlink/discard existing files (content-matching)
• download
  • ☑ single files in browser
  • ✖ folders as zip files
  • ☑ FUSE client (read-only)
• browser
  • ☑ tree-view
  • ☑ media player
  • ✖ thumbnails
  • ✖ SPA (browse while uploading)
    • currently safe using the file-tree on the left only, not folders in the file list
• server indexing
  • ☑ locate files by contents
  • ☑ search by name/path/date/size
  • ✖ search by ID3-tags etc.
• markdown
  • ☑ viewer
  • ☑ editor (sure why not)

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

bugs

• probably, pls let me know

searching

when started with -e2dsa copyparty will scan/index all your files. This avoids duplicates on upload, and also makes the volumes searchable through the web-ui:

• make search queries by size/date/directory-path/filename, or...
• drag/drop a local file to see if the same contents exist somewhere on the server (you get the URL if it does)

path/name queries are space-separated, AND'ed together, and words are negated with a - prefix, so for example:

• path: shibayan -bossa finds all files where one of the folders contain shibayan but filters out any results where bossa exists somewhere in the path
• name: demetori styx gives you good stuff

other metadata (like song tags etc) are not yet indexed for searching

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');

• curl/wget: upload some files (post=file, chunk=stdin)

  • post(){ curl -b cppwd=wark http://127.0.0.1:3923/ -F act=bput -F f=@"$1";}
post movie.mkv
  • post(){ wget --header='Cookie: cppwd=wark' http://127.0.0.1:3923/?raw --post-file="$1" -O-;}
post movie.mkv
  • chunk(){ curl -b cppwd=wark http://127.0.0.1:3923/ -T-;}
chunk <movie.mkv

• 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

copyparty returns a truncated sha512sum of your PUT/POST as base64; you can generate the same checksum locally to verify uplaods:

b512(){ printf "$((sha512sum||shasum -a512)|sed -E 's/ .*//;s/(..)/\\x\1/g')"|base64|head -c43;}
b512 <movie.mkv

dependencies

• jinja2

optional, will eventually enable thumbnails:

• Pillow (requires py2.7 or py3.5+)

sfx

currently there are two self-contained binaries:

• copyparty-sfx.py -- pure python, works everywhere
• copyparty-sfx.sh -- smaller, but only for linux and macos

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 :||||
