# βπ copyparty
* http file sharing hub (py2/py3) [(on PyPI)](https://pypi.org/project/copyparty/)
* 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 *any* web browser
* server only needs `py2.7` or `py3.3+`, all dependencies optional
* browse/upload with IE4 / netscape4.0 on win3.11 (heh)
* *resumable* uploads need `firefox 34+` / `chrome 41+` / `safari 7+` for full speed
* code standard: `black`

## quickstart
download **[copyparty-sfx.py](https://github.com/9001/copyparty/releases/latest/download/copyparty-sfx.py)** and you're all set!
running the sfx without arguments (for example doubleclicking it on Windows) will give everyone read/write access to the current folder; see `-h` for help if you want [accounts and volumes](#accounts-and-volumes) etc
some recommended options:
* `-e2dsa` enables general [file indexing](#file-indexing)
* `-e2ts` enables audio metadata indexing (needs either FFprobe or Mutagen), see [optional dependencies](#optional-dependencies)
* `-v /mnt/music:/music:r:rw,foo -a foo:bar` shares `/mnt/music` as `/music`, `r`eadable by anyone, and read-write for user `foo`, password `bar`
* replace `:r:rw,foo` with `:r,foo` to only make the folder readable by `foo` and nobody else
* see [accounts and volumes](#accounts-and-volumes) for the syntax and other permissions (`r`ead, `w`rite, `m`ove, `d`elete, `g`et)
* `--ls '**,*,ln,p,r'` to crash on startup if any of the volumes contain a symlink which point outside the volume, as that could give users unintended access
### on servers
you may also want these, especially on servers:
* [contrib/systemd/copyparty.service](contrib/systemd/copyparty.service) to run copyparty as a systemd service
* [contrib/systemd/prisonparty.service](contrib/systemd/prisonparty.service) to run it in a chroot (for extra security)
* [contrib/nginx/copyparty.conf](contrib/nginx/copyparty.conf) to reverse-proxy behind nginx (for better https)
### on debian
recommended additional steps on debian which enable audio metadata and thumbnails (from images and videos):
* as root, run the following:
`apt install python3 python3-pip python3-dev ffmpeg`
* then, as the user which will be running copyparty (so hopefully not root), run this:
`python3 -m pip install --user -U Pillow pillow-avif-plugin`
(skipped `pyheif-pillow-opener` because apparently debian is too old to build it)
## notes
general notes:
* 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
browser-specific:
* iPhone/iPad: use Firefox to download files
* Android-Chrome: increase "parallel uploads" for higher speed (android bug)
* Android-Firefox: takes a while to select files (their fix for βοΈ)
* Desktop-Firefox: ~~may use gigabytes of RAM if your files are massive~~ *seems to be OK now*
* Desktop-Firefox: may stop you from deleting files you've uploaded until you visit `about:memory` and click `Minimize memory usage`

## testimonials
small collection of user feedback
`good enough`, `surprisingly correct`, `certified good software`, `just works`, `why`
# motivations
project goals / philosophy
* inverse linux philosophy -- do all the things, and do an *okay* job
* quick drop-in service to get a lot of features in a pinch
* there are probably [better alternatives](https://github.com/awesome-selfhosted/awesome-selfhosted) if you have specific/long-term needs
* run anywhere, support everything
* as many web-browsers and python versions as possible
* every browser should at least be able to browse, download, upload files
* be a good emergency solution for transferring stuff between ancient boxes
* minimal dependencies
* but optional dependencies adding bonus-features are ok
* everything being plaintext makes it possible to proofread for malicious code
* no preparations / setup necessary, just run the sfx (which is also plaintext)
* adaptable, malleable, hackable
* no build steps; modify the js/python without needing node.js or anything like that
## future plans
some improvement ideas
* the JS is a mess -- a preact rewrite would be nice
* preferably without build dependencies like webpack/babel/node.js, maybe a python thing to assemble js files into main.js
* good excuse to look at using virtual lists (browsers start to struggle when folders contain over 5000 files)
* the UX is a mess -- a proper design would be nice
* very organic (much like the python/js), everything was an afterthought
* true for both the layout and the visual flair
* something like the tron board-room ui (or most other hollywood ones, like ironman) would be :100:
* some of the python files are way too big
* `up2k.py` ended up doing all the file indexing / db management
* `httpcli.py` should be separated into modules in general
# bugs
* Windows: python 3.7 and older cannot read tags with FFprobe, so use Mutagen or upgrade
* Windows: python 2.7 cannot index non-ascii filenames with `-e2d`
* Windows: python 2.7 cannot handle filenames with mojibake
* `--th-ff-jpg` may fix video thumbnails on some FFmpeg versions (macos, some linux)
* `--th-ff-swr` may fix audio thumbnails on some FFmpeg versions
## general bugs
* Windows: if the up2k db is on a samba-share or network disk, you'll get unpredictable behavior if the share is disconnected for a bit
* use `--hist` or the `hist` volflag (`-v [...]:c,hist=/tmp/foo`) to place the db on a local disk instead
* all volumes must exist / be available on startup; up2k (mtp especially) gets funky otherwise
* probably more, pls let me know
## not my bugs
* iPhones: the volume control doesn't work because [apple doesn't want it to](https://developer.apple.com/library/archive/documentation/AudioVideo/Conceptual/Using_HTML5_Audio_Video/Device-SpecificConsiderations/Device-SpecificConsiderations.html#//apple_ref/doc/uid/TP40009523-CH5-SW11)
* *future workaround:* enable the equalizer, make it all-zero, and set a negative boost to reduce the volume
* "future" because `AudioContext` is broken in the current iOS version (15.1), maybe one day...
* Windows: folders cannot be accessed if the name ends with `.`
* python or windows bug
* Windows: msys2-python 3.8.6 occasionally throws `RuntimeError: release unlocked lock` when leaving a scoped mutex in up2k
* this is an msys2 bug, the regular windows edition of python is fine
* VirtualBox: sqlite throws `Disk I/O Error` when running in a VM and the up2k database is in a vboxsf
* use `--hist` or the `hist` volflag (`-v [...]:c,hist=/tmp/foo`) to place the db inside the vm instead
# FAQ
"frequently" asked questions
* is it possible to block read-access to folders unless you know the exact URL for a particular file inside?
* yes, using the [`g` permission](#accounts-and-volumes), see the examples there
* you can also do this with linux filesystem permissions; `chmod 111 music` will make it possible to access files and folders inside the `music` folder but not list the immediate contents -- also works with other software, not just copyparty
* can I make copyparty download a file to my server if I give it a URL?
* not officially, but there is a [terrible hack](https://github.com/9001/copyparty/blob/hovudstraum/bin/mtag/wget.py) which makes it possible
# accounts and volumes
per-folder, per-user permissions - if your setup is getting complex, consider making a [config file](./docs/example.conf) instead of using arguments
* much easier to manage, and you can modify the config at runtime with `systemctl reload copyparty` or more conveniently using the `[reload cfg]` button in the control-panel (if logged in as admin)
configuring accounts/volumes with arguments:
* `-a usr:pwd` adds account `usr` with password `pwd`
* `-v .::r` adds current-folder `.` as the webroot, `r`eadable by anyone
* the syntax is `-v src:dst:perm:perm:...` so local-path, url-path, and one or more permissions to set
* granting the same permissions to multiple accounts:
`-v .::r,usr1,usr2:rw,usr3,usr4` = usr1/2 read-only, 3/4 read-write
permissions:
* `r` (read): browse folder contents, download files, download as zip/tar
* `w` (write): upload files, move files *into* this folder
* `m` (move): move files/folders *from* this folder
* `d` (delete): delete files/folders
* `g` (get): only download files, cannot see folder contents or zip/tar
examples:
* add accounts named u1, u2, u3 with passwords p1, p2, p3: `-a u1:p1 -a u2:p2 -a u3:p3`
* make folder `/srv` the root of the filesystem, read-only by anyone: `-v /srv::r`
* make folder `/mnt/music` available at `/music`, read-only for u1 and u2, read-write for u3: `-v /mnt/music:music:r,u1,u2:rw,u3`
* unauthorized users accessing the webroot can see that the `music` folder exists, but cannot open it
* make folder `/mnt/incoming` available at `/inc`, write-only for u1, read-move for u2: `-v /mnt/incoming:inc:w,u1:rm,u2`
* unauthorized users accessing the webroot can see that the `inc` folder exists, but cannot open it
* `u1` can open the `inc` folder, but cannot see the contents, only upload new files to it
* `u2` can browse it and move files *from* `/inc` into any folder where `u2` has write-access
* make folder `/mnt/ss` available at `/i`, read-write for u1, get-only for everyone else, and enable accesskeys: `-v /mnt/ss:i:rw,u1:g:c,fk=4`
* `c,fk=4` sets the `fk` volume-flag to 4, meaning each file gets a 4-character accesskey
* `u1` can upload files, browse the folder, and see the generated accesskeys
* other users cannot browse the folder, but can access the files if they have the full file URL with the accesskey
# the browser
accessing a copyparty server using a web-browser
## tabs
the main tabs in the ui
* `[π]` [search](#searching) by size, date, path/name, mp3-tags ...
* `[π§―]` [unpost](#unpost): undo/delete accidental uploads
* `[π]` and `[π]` are the [uploaders](#uploading)
* `[π]` mkdir: create directories
* `[π]` new-md: create a new markdown document
* `[π]` send-msg: either to server-log or into textfiles if `--urlform save`
* `[πΊ]` audio-player config options
* `[βοΈ]` general client config options
## hotkeys
the browser has the following hotkeys (always qwerty)
* `B` toggle breadcrumbs / [navpane](#navpane)
* `I/K` prev/next folder
* `M` parent folder (or unexpand current)
* `V` toggle folders / textfiles in the navpane
* `G` toggle list / [grid view](#thumbnails)
* `T` toggle thumbnails / icons
* `ESC` close various things
* `ctrl-X` cut selected files/folders
* `ctrl-V` paste

* when a file/folder is selected (in not-grid-view):
* `Up/Down` move cursor
* shift+`Up/Down` select and move cursor
* ctrl+`Up/Down` move cursor and scroll viewport
* `Space` toggle file selection
* `Ctrl-A` toggle select all
* when a textfile is open:
* `I/K` prev/next textfile
* `S` toggle selection of open file
* `M` close textfile
* when playing audio:
* `J/L` prev/next song
* `U/O` skip 10sec back/forward
* `0..9` jump to 0%..90%
* `P` play/pause (also starts playing the folder)
* when viewing images / playing videos:

* `F` fullscreen
* `C` continue playing next video
* `V` loop
* `M` mute
* when the navpane is open:
* `A/D` adjust tree width
* in the [grid view](#thumbnails):
* `S` toggle multiselect
* shift+`A/D` zoom
* in the markdown editor:
* `^s` save
* `^h` header
* `^k` autoformat table
* `^u` jump to next unicode character
* `^e` toggle editor / preview
* `^up, ^down` jump paragraphs
## navpane
switching between breadcrumbs or navpane
click the `π²` or pressing the `B` hotkey to toggle between breadcrumbs path (default), or a navpane (tree-browser sidebar thing)
* `[+]` and `[-]` (or hotkeys `A`/`D`) adjust the size
* `[π―]` jumps to the currently open folder
* `[π]` toggles between showing folders and textfiles
* `[π]` shows the name of all parent folders in a docked panel
* `[a]` toggles automatic widening as you go deeper
* `[β΅]` toggles wordwrap
* `[π]` show full name on hover (if wordwrap is off)
## thumbnails
press `g` to toggle grid-view instead of the file listing, and `t` toggles icons / thumbnails
it does static images with Pillow and uses FFmpeg for video files, so you may want to `--no-thumb` or maybe just `--no-vthumb` depending on how dangerous your users are
audio files are covnerted into spectrograms using FFmpeg unless you `--no-athumb` (and some FFmpeg builds may need `--th-ff-swr`)
images with the following names (see `--th-covers`) become the thumbnail of the folder they're in: `folder.png`, `folder.jpg`, `cover.png`, `cover.jpg`
in the grid/thumbnail view, if the audio player panel is open, songs will start playing when clicked
* indicated by the audio files having the βΆ icon instead of πΎ
## zip downloads
download folders (or file selections) as `zip` or `tar` files
select which type of archive you want in the `[βοΈ] config` tab:
| name | url-suffix | description |
|--|--|--|
| `tar` | `?tar` | plain gnutar, works great with `curl \| tar -xv` |
| `zip` | `?zip=utf8` | works everywhere, glitchy filenames on win7 and older |
| `zip_dos` | `?zip` | traditional cp437 (no unicode) to fix glitchy filenames |
| `zip_crc` | `?zip=crc` | cp437 with crc32 computed early for truly ancient software |
* hidden files (dotfiles) are excluded unless `-ed`
* `up2k.db` and `dir.txt` is always excluded
* `zip_crc` will take longer to download since the server has to read each file twice
* this is only to support MS-DOS PKZIP v2.04g (october 1993) and older
* how are you accessing copyparty actually
you can also zip a selection of files or folders by clicking them in the browser, that brings up a selection editor and zip button in the bottom right
## uploading
drag files/folders into the web-browser to upload
this initiates an upload using `up2k`; there are two uploaders available:
* `[π] bup`, the basic uploader, supports almost every browser since netscape 4.0
* `[π] up2k`, the fancy one
you can also undo/delete uploads by using `[π§―]` [unpost](#unpost)
up2k has several advantages:
* you can drop folders into the browser (files are added recursively)
* files are processed in chunks, and each chunk is checksummed
* uploads autoresume if they are interrupted by network issues
* uploads resume if you reboot your browser or pc, just upload the same files again
* server detects any corruption; the client reuploads affected chunks
* the client doesn't upload anything that already exists on the server
* much higher speeds than ftp/scp/tarpipe on some internet connections (mainly american ones) thanks to parallel connections
* the last-modified timestamp of the file is preserved
see [up2k](#up2k) for details on how it works
**protip:** you can avoid scaring away users with [contrib/plugins/minimal-up2k.html](contrib/plugins/minimal-up2k.html) which makes it look [much simpler](https://user-images.githubusercontent.com/241032/118311195-dd6ca380-b4ef-11eb-86f3-75a3ff2e1332.png)
**protip:** if you enable `favicon` in the `[βοΈ] settings` tab (by typing something into the textbox), the icon in the browser tab will indicate upload progress
the up2k UI is the epitome of polished inutitive experiences:
* "parallel uploads" specifies how many chunks to upload at the same time
* `[π]` analysis of other files should continue while one is uploading
* `[π]` ask for confirmation before files are added to the queue
* `[π€]` sync uploading between other copyparty browser-tabs so only one is active
* `[π]` switch between upload and [file-search](#file-search) mode
* ignore `[π]` if you add files by dragging them into the browser
and then theres the tabs below it,
* `[ok]` is the files which completed successfully
* `[ng]` is the ones that failed / got rejected (already exists, ...)
* `[done]` shows a combined list of `[ok]` and `[ng]`, chronological order
* `[busy]` files which are currently hashing, pending-upload, or uploading
* plus up to 3 entries each from `[done]` and `[que]` for context
* `[que]` is all the files that are still queued
note that since up2k has to read each file twice, `[π bup]` can *theoretically* be up to 2x faster in some extreme cases (files bigger than your ram, combined with an internet connection faster than the read-speed of your HDD, or if you're uploading from a cuo2duo)
if you are resuming a massive upload and want to skip hashing the files which already finished, you can enable `turbo` in the `[βοΈ] config` tab, but please read the tooltip on that button
### file-search
dropping files into the browser also lets you see if they exist on the server
when you drag/drop files into the browser, you will see two dropzones: `Upload` and `Search`
> on a phone? toggle the `[π]` switch green before tapping the big yellow Search button to select your files
the files will be hashed on the client-side, and each hash is sent to the server, which checks if that file exists somewhere
files go into `[ok]` if they exist (and you get a link to where it is), otherwise they land in `[ng]`
* the main reason filesearch is combined with the uploader is cause the code was too spaghetti to separate it out somewhere else, this is no longer the case but now i've warmed up to the idea too much
### unpost
undo/delete accidental uploads
you can unpost even if you don't have regular move/delete access, however only for files uploaded within the past `--unpost` seconds (default 12 hours) and the server must be running with `-e2d`
## file manager
cut/paste, rename, and delete files/folders (if you have permission)
file selection: click somewhere on the line (not the link itsef), then:
* `space` to toggle
* `up/down` to move
* `shift-up/down` to move-and-select
* `ctrl-shift-up/down` to also scroll
* cut: select some files and `ctrl-x`
* paste: `ctrl-v` in another folder
* rename: `F2`
you can move files across browser tabs (cut in one tab, paste in another)
## batch rename
select some files and press `F2` to bring up the rename UI
quick explanation of the buttons,
* `[β
apply rename]` confirms and begins renaming
* `[β cancel]` aborts and closes the rename window
* `[βΊ reset]` reverts any filename changes back to the original name
* `[decode]` does a URL-decode on the filename, fixing stuff like `&` and `%20`
* `[advanced]` toggles advanced mode
advanced mode: rename files based on rules to decide the new names, based on the original name (regex), or based on the tags collected from the file (artist/title/...), or a mix of both
in advanced mode,
* `[case]` toggles case-sensitive regex
* `regex` is the regex pattern to apply to the original filename; any files which don't match will be skipped
* `format` is the new filename, taking values from regex capturing groups and/or from file tags
* very loosely based on foobar2000 syntax
* `presets` lets you save rename rules for later
available functions:
* `$lpad(text, length, pad_char)`
* `$rpad(text, length, pad_char)`
so,
say you have a file named [`meganeko - Eclipse - 07 Sirius A.mp3`](https://www.youtube.com/watch?v=-dtb0vDPruI) (absolutely fantastic album btw) and the tags are: `Album:Eclipse`, `Artist:meganeko`, `Title:Sirius A`, `tn:7`
you could use just regex to rename it:
* `regex` = `(.*) - (.*) - ([0-9]{2}) (.*)`
* `format` = `(3). (1) - (4)`
* `output` = `07. meganeko - Sirius A.mp3`
or you could use just tags:
* `format` = `$lpad((tn),2,0). (artist) - (title).(ext)`
* `output` = `7. meganeko - Sirius A.mp3`
or a mix of both:
* `regex` = ` - ([0-9]{2}) `
* `format` = `(1). (artist) - (title).(ext)`
* `output` = `07. meganeko - Sirius A.mp3`
the metadata keys you can use in the format field are the ones in the file-browser table header (whatever is collected with `-mte` and `-mtp`)
## markdown viewer
and there are *two* editors
* the document preview has a max-width which is the same as an A4 paper when printed
## other tricks
* you can link a particular timestamp in an audio file by adding it to the URL, such as `&20` / `&20s` / `&1m20` / `&t=1:20` after the `.../#af-c8960dab`
* enabling the audio equalizer can help make gapless albums fully gapless in some browsers (chrome), so consider leaving it on with all the values at zero
* get a plaintext file listing by adding `?ls=t` to a URL, or a compact colored one with `?ls=v` (for unix terminals)
* if you are using media hotkeys to switch songs and are getting tired of seeing the OSD popup which Windows doesn't let you disable, consider https://ocv.me/dev/?media-osd-bgone.ps1
* click the bottom-left `Ο` to open a javascript prompt for debugging
* files named `.prologue.html` / `.epilogue.html` will be rendered before/after directory listings unless `--no-logues`
* files named `README.md` / `readme.md` will be rendered after directory listings unless `--no-readme` (but `.epilogue.html` takes precedence)

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, see [file-search](#file-search)
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](https://www.youtube.com/watch?v=zGh0g14ZJ8I&list=PL3A147BD151EE5218&index=9)
add the argument `-e2ts` to also scan/index tags from music files, which brings us over to:
# server config
using arguments or config files, or a mix of both:
* config files (`-c some.conf`) can set additional commandline arguments; see [./docs/example.conf](docs/example.conf)
* `kill -s USR1` (same as `systemctl reload copyparty`) to reload accounts and volumes from config files without restarting
* or click the `[reload cfg]` button in the control-panel when logged in as admin
## ftp-server
an FTP server can be started using `--ftp 3921`, and/or `--ftps` for explicit TLS (ftpes)
* based on [pyftpdlib](https://github.com/giampaolo/pyftpdlib)
* needs a dedicated port (cannot share with the HTTP/HTTPS API)
* uploads are not resumable -- delete and restart if necessary
* runs in active mode by default, you probably want `--ftp-pr 12000-13000`
* if you enable both `ftp` and `ftps`, the port-range will be divided in half
## file indexing
file indexing relies on two database tables, the up2k filetree (`-e2d`) and the metadata tags (`-e2t`), stored in `.hist/up2k.db`. Configuration can be done through arguments, volume flags, or a mix of both.
through arguments:
* `-e2d` enables file indexing on upload
* `-e2ds` also scans writable folders for new files on startup
* `-e2dsa` also scans all mounted volumes (including readonly ones)
* `-e2t` enables metadata indexing on upload
* `-e2ts` also scans for tags in all files that don't have tags yet
* `-e2tsr` also deletes all existing tags, doing a full reindex
the same arguments can be set as volume flags, in addition to `d2d`, `d2ds`, `d2t`, `d2ts` for disabling:
* `-v ~/music::r:c,e2dsa,e2tsr` does a full reindex of everything on startup
* `-v ~/music::r:c,d2d` disables **all** indexing, even if any `-e2*` are on
* `-v ~/music::r:c,d2t` disables all `-e2t*` (tags), does not affect `-e2d*`
* `-v ~/music::r:c,d2ds` disables on-boot scans; only index new uploads
* `-v ~/music::r:c,d2ts` same except only affecting tags
note:
* the parser can finally handle `c,e2dsa,e2tsr` so you no longer have to `c,e2dsa:c,e2tsr`
* `e2tsr` is probably always overkill, since `e2ds`/`e2dsa` would pick up any file modifications and `e2ts` would then reindex those, unless there is a new copyparty version with new parsers and the release note says otherwise
* the rescan button in the admin panel has no effect unless the volume has `-e2ds` or higher
to save some time, you can provide a regex pattern for filepaths to only index by filename/path/size/last-modified (and not the hash of the file contents) by setting `--no-hash \.iso$` or the volume-flag `:c,nohash=\.iso$`, this has the following consequences:
* initial indexing is way faster, especially when the volume is on a network disk
* makes it impossible to [file-search](#file-search)
* if someone uploads the same file contents, the upload will not be detected as a dupe, so it will not get symlinked or rejected
similarly, you can fully ignore files/folders using `--no-idx [...]` and `:c,noidx=\.iso$`
if you set `--no-hash [...]` globally, you can enable hashing for specific volumes using flag `:c,nohash=`
## upload rules
set upload rules using volume flags, some examples:
* `:c,sz=1k-3m` sets allowed filesize between 1 KiB and 3 MiB inclusive (suffixes: `b`, `k`, `m`, `g`)
* `:c,nosub` disallow uploading into subdirectories; goes well with `rotn` and `rotf`:
* `:c,rotn=1000,2` moves uploads into subfolders, up to 1000 files in each folder before making a new one, two levels deep (must be at least 1)
* `:c,rotf=%Y/%m/%d/%H` enforces files to be uploaded into a structure of subfolders according to that date format
* if someone uploads to `/foo/bar` the path would be rewritten to `/foo/bar/2021/08/06/23` for example
* but the actual value is not verified, just the structure, so the uploader can choose any values which conform to the format string
* just to avoid additional complexity in up2k which is enough of a mess already
* `:c,lifetime=300` delete uploaded files when they become 5 minutes old
you can also set transaction limits which apply per-IP and per-volume, but these assume `-j 1` (default) otherwise the limits will be off, for example `-j 4` would allow anywhere between 1x and 4x the limits you set depending on which processing node the client gets routed to
* `:c,maxn=250,3600` allows 250 files over 1 hour from each IP (tracked per-volume)
* `:c,maxb=1g,300` allows 1 GiB total over 5 minutes from each IP (tracked per-volume)
## compress uploads
files can be autocompressed on upload, either on user-request (if config allows) or forced by server-config
* volume flag `gz` allows gz compression
* volume flag `xz` allows lzma compression
* volume flag `pk` **forces** compression on all files
* url parameter `pk` requests compression with server-default algorithm
* url parameter `gz` or `xz` requests compression with a specific algorithm
* url parameter `xz` requests xz compression
things to note,
* the `gz` and `xz` arguments take a single optional argument, the compression level (range 0 to 9)
* the `pk` volume flag takes the optional argument `ALGORITHM,LEVEL` which will then be forced for all uploads, for example `gz,9` or `xz,0`
* default compression is gzip level 9
* all upload methods except up2k are supported
* the files will be indexed after compression, so dupe-detection and file-search will not work as expected
some examples,
* `-v inc:inc:w:c,pk=xz,0`
folder named inc, shared at inc, write-only for everyone, forces xz compression at level 0
* `-v inc:inc:w:c,pk`
same write-only inc, but forces gz compression (default) instead of xz
* `-v inc:inc:w:c,gz`
allows (but does not force) gz compression if client uploads to `/inc?pk` or `/inc?gz` or `/inc?gz=4`
## database location
in-volume (`.hist/up2k.db`, default) or somewhere else
copyparty creates a subfolder named `.hist` inside each volume where it stores the database, thumbnails, and some other stuff
this can instead be kept in a single place using the `--hist` argument, or the `hist=` volume flag, or a mix of both:
* `--hist ~/.cache/copyparty -v ~/music::r:c,hist=-` sets `~/.cache/copyparty` as the default place to put volume info, but `~/music` gets the regular `.hist` subfolder (`-` restores default behavior)
note:
* markdown edits are always stored in a local `.hist` subdirectory
* on windows the volflag path is cyglike, so `/c/temp` means `C:\temp` but use regular paths for `--hist`
* you can use cygpaths for volumes too, `-v C:\Users::r` and `-v /c/users::r` both work
## metadata from audio files
set `-e2t` to index tags on upload
`-mte` decides which tags to index and display in the browser (and also the display order), this can be changed per-volume:
* `-v ~/music::r:c,mte=title,artist` indexes and displays *title* followed by *artist*
if you add/remove a tag from `mte` you will need to run with `-e2tsr` once to rebuild the database, otherwise only new files will be affected
but instead of using `-mte`, `-mth` is a better way to hide tags in the browser: these tags will not be displayed by default, but they still get indexed and become searchable, and users can choose to unhide them in the `[βοΈ] config` pane
`-mtm` can be used to add or redefine a metadata mapping, say you have media files with `foo` and `bar` tags and you want them to display as `qux` in the browser (preferring `foo` if both are present), then do `-mtm qux=foo,bar` and now you can `-mte artist,title,qux`
tags that start with a `.` such as `.bpm` and `.dur`(ation) indicate numeric value
see the beautiful mess of a dictionary in [mtag.py](https://github.com/9001/copyparty/blob/hovudstraum/copyparty/mtag.py) for the default mappings (should cover mp3,opus,flac,m4a,wav,aif,)
`--no-mutagen` disables Mutagen and uses FFprobe instead, which...
* is about 20x slower than Mutagen
* catches a few tags that Mutagen doesn't
* melodic key, video resolution, framerate, pixfmt
* avoids pulling any GPL code into copyparty
* more importantly runs FFprobe on incoming files which is bad if your FFmpeg has a cve
## file parser plugins
provide custom parsers to index additional tags, also see [./bin/mtag/README.md](./bin/mtag/README.md)
copyparty can invoke external programs to collect additional metadata for files using `mtp` (either as argument or volume flag), there is a default timeout of 30sec
* `-mtp .bpm=~/bin/audio-bpm.py` will execute `~/bin/audio-bpm.py` with the audio file as argument 1 to provide the `.bpm` tag, if that does not exist in the audio metadata
* `-mtp key=f,t5,~/bin/audio-key.py` uses `~/bin/audio-key.py` to get the `key` tag, replacing any existing metadata tag (`f,`), aborting if it takes longer than 5sec (`t5,`)
* `-v ~/music::r:c,mtp=.bpm=~/bin/audio-bpm.py:c,mtp=key=f,t5,~/bin/audio-key.py` both as a per-volume config wow this is getting ugly
*but wait, there's more!* `-mtp` can be used for non-audio files as well using the `a` flag: `ay` only do audio files, `an` only do non-audio files, or `ad` do all files (d as in dontcare)
* `-mtp ext=an,~/bin/file-ext.py` runs `~/bin/file-ext.py` to get the `ext` tag only if file is not audio (`an`)
* `-mtp arch,built,ver,orig=an,eexe,edll,~/bin/exe.py` runs `~/bin/exe.py` to get properties about windows-binaries only if file is not audio (`an`) and file extension is exe or dll
## upload events
trigger a script/program on each upload like so:
```
-v /mnt/inc:inc:w:c,mte=+a1:c,mtp=a1=ad,/usr/bin/notify-send
```
so filesystem location `/mnt/inc` shared at `/inc`, write-only for everyone, appending `a1` to the list of tags to index, and using `/usr/bin/notify-send` to "provide" that tag
that'll run the command `notify-send` with the path to the uploaded file as the first and only argument (so on linux it'll show a notification on-screen)
note that it will only trigger on new unique files, not dupes
and it will occupy the parsing threads, so fork anything expensive, or if you want to intentionally queue/singlethread you can combine it with `--mtag-mt 1`
if this becomes popular maybe there should be a less janky way to do it actually
## complete examples
* read-only music server with bpm and key scanning
`python copyparty-sfx.py -v /mnt/nas/music:/music:r -e2dsa -e2ts -mtp .bpm=f,audio-bpm.py -mtp key=f,audio-key.py`

quick summary of more eccentric web-browsers trying to view a directory index:
| browser | will it blend |
| ------- | ------------- |
| **links** (2.21/macports) | can browse, login, upload/mkdir/msg |
| **lynx** (2.8.9/macports) | can browse, login, upload/mkdir/msg |
| **w3m** (0.5.3/macports) | can browse, login, upload at 100kB/s, mkdir/msg |
| **netsurf** (3.10/arch) | is basically ie6 with much better css (javascript has almost no effect) |
| **opera** (11.60/winxp) | OK: thumbnails, image-viewer, zip-selection, rename/cut/paste. NG: up2k, navpane, markdown, audio |
| **ie4** and **netscape** 4.0 | can browse, upload with `?b=u` |
| **SerenityOS** (7e98457) | hits a page fault, works with `?b=u`, file upload not-impl |
# client examples
interact with copyparty using non-browser clients
* javascript: dump some state into a file (two separate examples)
* `await fetch('//127.0.0.1:3923/', {method:"PUT", body: JSON.stringify(foo)});`
* `var xhr = new XMLHttpRequest(); xhr.open('POST', '//127.0.0.1:3923/msgs?raw'); xhr.send('foo');`
* curl/wget: upload some files (post=file, chunk=stdin)
* `post(){ curl -b cppwd=wark -F act=bput -F f=@"$1" http://127.0.0.1:3923/;}`
`post movie.mkv`
* `post(){ wget --header='Cookie: cppwd=wark' --post-file="$1" -O- http://127.0.0.1:3923/?raw;}`
`post movie.mkv`
* `chunk(){ curl -b cppwd=wark -T- http://127.0.0.1:3923/;}`
`chunk /dev/tcp/127.0.0.1/3923`
* python: [up2k.py](https://github.com/9001/copyparty/blob/hovudstraum/bin/up2k.py) is a command-line up2k client [(webm)](https://ocv.me/stuff/u2cli.webm)
* file uploads, file-search, autoresume of aborted/broken uploads
* see [./bin/README.md#up2kpy](bin/README.md#up2kpy)
* FUSE: mount a copyparty server as a local filesystem
* cross-platform python client available in [./bin/](bin/)
* [rclone](https://rclone.org/) as client can give ~5x performance, see [./docs/rclone.md](docs/rclone.md)
* sharex (screenshot utility): see [./contrib/sharex.sxcu](contrib/#sharexsxcu)
copyparty returns a truncated sha512sum of your PUT/POST as base64; you can generate the same checksum locally to verify uplaods:
b512(){ printf "$((sha512sum||shasum -a512)|sed -E 's/ .*//;s/(..)/\\x\1/g')"|base64|tr '+/' '-_'|head -c44;}
b512 = 32M
* client posts the list of hashes, filename, size, last-modified
* server creates the `wark`, an identifier for this upload
* `sha512( salt + filesize + chunk_hashes )`
* and a sparse file is created for the chunks to drop into
* client uploads each chunk
* header entries for the chunk-hash and wark
* server writes chunks into place based on the hash
* client does another handshake with the hashlist; server replies with OK or a list of chunks to reupload
up2k has saved a few uploads from becoming corrupted in-transfer already; caught an android phone on wifi redhanded in wireshark with a bitflip, however bup with https would *probably* have noticed as well (thanks to tls also functioning as an integrity check)
## why chunk-hashes
a single sha512 would be better, right?
this is due to `crypto.subtle` not providing a streaming api (or the option to seed the sha512 hasher with a starting hash)
as a result, the hashes are much less useful than they could have been (search the server by sha512, provide the sha512 in the response http headers, ...)
hashwasm would solve the streaming issue but reduces hashing speed for sha512 (xxh128 does 6 GiB/s), and it would make old browsers and [iphones](https://bugs.webkit.org/show_bug.cgi?id=228552) unsupported
# performance
defaults are usually fine - expect `8 GiB/s` download, `1 GiB/s` upload
below are some tweaks roughly ordered by usefulness:
* `-q` disables logging and can help a bunch, even when combined with `-lo` to redirect logs to file
* `--http-only` or `--https-only` (unless you want to support both protocols) will reduce the delay before a new connection is established
* `--hist` pointing to a fast location (ssd) will make directory listings and searches faster when `-e2d` or `-e2t` is set
* `--no-hash .` when indexing a network-disk if you don't care about the actual filehashes and only want the names/tags searchable
* `-j` enables multiprocessing (actual multithreading) and can make copyparty perform better in cpu-intensive workloads, for example:
* huge amount of short-lived connections
* really heavy traffic (downloads/uploads)
...however it adds an overhead to internal communication so it might be a net loss, see if it works 4 u
## client-side
when uploading files,
* chrome is recommended, at least compared to firefox:
* up to 90% faster when hashing, especially on SSDs
* up to 40% faster when uploading over extremely fast internets
* but [up2k.py](https://github.com/9001/copyparty/blob/hovudstraum/bin/up2k.py) can be 40% faster than chrome again
* if you're cpu-bottlenecked, or the browser is maxing a cpu core:
* up to 30% faster uploads if you hide the upload status list by switching away from the `[π]` up2k ui-tab (or closing it)
* switching to another browser-tab also works, the favicon will update every 10 seconds in that case
* unlikely to be a problem, but can happen when uploding many small files, or your internet is too fast, or PC too slow
# security
some notes on hardening
on public copyparty instances with anonymous upload enabled:
* users can upload html/css/js which will evaluate for other visitors in a few ways,
* unless `--no-readme` is set: by uploading/modifying a file named `readme.md`
* if `move` access is granted AND none of `--no-logues`, `--no-dot-mv`, `--no-dot-ren` is set: by uploading some .html file and renaming it to `.epilogue.html` (uploading it directly is blocked)
other misc:
* you can disable directory listings by giving permission `g` instead of `r`, only accepting direct URLs to files
* combine this with volume-flag `c,fk` to generate per-file accesskeys; users which have full read-access will then see URLs with `?k=...` appended to the end, and `g` users must provide that URL including the correct key to avoid a 404
## gotchas
behavior that might be unexpected
* users without read-access to a folder can still see the `.prologue.html` / `.epilogue.html` / `README.md` contents, for the purpose of showing a description on how to use the uploader for example
# recovering from crashes
## client crashes
### frefox wsod
firefox 87 can crash during uploads -- the entire browser goes, including all other browser tabs, everything turns white
however you can hit `F12` in the up2k tab and use the devtools to see how far you got in the uploads:
* get a complete list of all uploads, organized by statuts (ok / no-good / busy / queued):
`var tabs = { ok:[], ng:[], bz:[], q:[] }; for (var a of up2k.ui.tab) tabs[a.in].push(a); tabs`
* list of filenames which failed:
`βvar ng = []; for (var a of up2k.ui.tab) if (a.in != 'ok') ng.push(a.hn.split('')[0]); ng`
* send the list of filenames to copyparty for safekeeping:
`await fetch('/inc', {method:'PUT', body:JSON.stringify(ng,null,1)})`
# HTTP API
* table-column `params` = URL parameters; `?foo=bar&qux=...`
* table-column `body` = POST payload
* method `jPOST` = json post
* method `mPOST` = multipart post
* method `uPOST` = url-encoded post
* `FILE` = conventional HTTP file upload entry (rfc1867 et al, filename in `Content-Disposition`)
authenticate using header `Cookie: cppwd=foo` or url param `&pw=foo`

# dependencies
mandatory deps:
* `jinja2` (is built into the SFX)
## optional dependencies
install these to enable bonus features
enable music tags:
* either `mutagen` (fast, pure-python, skips a few tags, makes copyparty GPL? idk)
* or `ffprobe` (20x slower, more accurate, possibly dangerous depending on your distro and users)
enable [thumbnails](#thumbnails) of...
* **images:** `Pillow` (requires py2.7 or py3.5+)
* **videos/audio:** `ffmpeg` and `ffprobe` somewhere in `$PATH`
* **HEIF pictures:** `pyheif-pillow-opener` (requires Linux or a C compiler)
* **AVIF pictures:** `pillow-avif-plugin`
## install recommended deps
```
python -m pip install --user -U jinja2 mutagen Pillow
```
## optional gpl stuff
some bundled tools have copyleft dependencies, see [./bin/#mtag](bin/#mtag)
these are standalone programs and will never be imported / evaluated by copyparty, and must be enabled through `-mtp` configs
# sfx
there are two self-contained "binaries":
* [copyparty-sfx.py](https://github.com/9001/copyparty/releases/latest/download/copyparty-sfx.py) -- pure python, works everywhere, **recommended**
* [copyparty-sfx.sh](https://github.com/9001/copyparty/releases/latest/download/copyparty-sfx.sh) -- smaller, but only for linux and macos, kinda deprecated
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
reduce the size of an sfx by removing features
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 if you're on windows then you need msys2 or WSL)
* `393k` size of original sfx.py as of v1.1.3
* `310k` after `./scripts/make-sfx.sh re no-cm`
* `269k` after `./scripts/make-sfx.sh re no-cm no-hl`
the features you can opt to drop are
* `cm`/easymde, the "fancy" markdown editor, saves ~82k
* `hl`, prism, the syntax hilighter, saves ~41k
* `fnt`, source-code-pro, the monospace font, saves ~9k
* `dd`, the custom mouse cursor for the media player tray tab, saves ~2k
for the `re`pack 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](scripts/copyparty-repack.sh) -- this will grab the latest copyparty release from github and do a few repacks; works on linux/macos (and windows with msys2 or WSL)
# install on android
install [Termux](https://termux.com/) (see [ocv.me/termux](https://ocv.me/termux/)) and then copy-paste this into Termux (long-tap) all at once:
```sh
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
# reporting bugs
ideas for context to include in bug reports
if something broke during an upload (replacing FILENAME with a part of the filename that broke):
```
journalctl -aS '48 hour ago' -u copyparty | grep -C10 FILENAME | tee bug.log
```
# building
## dev env setup
mostly optional; if you need a working env for vscode or similar
```sh
python3 -m venv .venv
. .venv/bin/activate
pip install jinja2 # mandatory
pip install mutagen # audio metadata
pip install Pillow pyheif-pillow-opener pillow-avif-plugin # thumbnails
pip install black bandit pylint flake8 # vscode tooling
```
## just the sfx
first grab the web-dependencies from a previous sfx (assuming you don't need to modify something in those):
```sh
rm -rf copyparty/web/deps
curl -L https://github.com/9001/copyparty/releases/latest/download/copyparty-sfx.py >x.py
python3 x.py -h
rm x.py
mv /tmp/pe-copyparty/copyparty/web/deps/ copyparty/web/deps/
```
then build the sfx using any of the following examples:
```sh
./scripts/make-sfx.sh # both python and sh editions
./scripts/make-sfx.sh no-sh gz # just python with gzip
```
## complete release
also builds the sfx so skip the sfx section above
in the `scripts` folder:
* run `make -C deps-docker` to build all dependencies
* `git tag v1.2.3 && git push origin --tags`
* upload to pypi with `make-pypi-release.(sh|bat)`
* create github release with `make-tgz-release.sh`
* create sfx with `make-sfx.sh`
# todo
roughly sorted by priority
* nothing! currently
## discarded ideas
* reduce up2k roundtrips
* start from a chunk index and just go
* terminate client on bad data
* not worth the effort, just throw enough conncetions at it
* single sha512 across all up2k chunks?
* crypto.subtle cannot into streaming, would have to use hashwasm, expensive
* separate sqlite table per tag
* performance fixed by skipping some indexes (`+mt.k`)
* audio fingerprinting
* only makes sense if there can be a wasm client and that doesn't exist yet (except for olaf which is agpl hence counts as not existing)
* `os.copy_file_range` for up2k cloning
* almost never hit this path anyways
* up2k partials ui
* feels like there isn't much point
* cache sha512 chunks on client
* too dangerous
* comment field
* nah
* look into android thumbnail cache file format
* absolutely not
* indexedDB for hashes, cfg enable/clear/sz, 2gb avail, ~9k for 1g, ~4k for 100m, 500k items before autoeviction
* blank hashlist when up-ok to skip handshake
* too many confusing side-effects
* hls framework for Someone Else to drop code into :^)
* probably not, too much stuff to consider -- seeking, start at offset, task stitching (probably np-hard), conditional passthru, rate-control (especially multi-consumer), session keepalive, cache mgmt...
