+            \033[0m
+            commands specified as --args are appended to volflags;
+            each --arg and volflag can be specified multiple times,
+            each command will execute in order unless one returns non-zero
+
+            optionally prefix the command with comma-sep. flags similar to -mtp:
+
+             \033[36mf\033[35m forks the process, doesn't wait for completion
+             \033[36mc\033[35m checks return code, blocks the action if non-zero
+             \033[36mj\033[35m provides json with info as 1st arg instead of filepath
+             \033[36mwN\033[35m waits N sec after command has been started before continuing
+             \033[36mtN\033[35m sets an N sec timeout before the command is abandoned
+
+             \033[36mkt\033[35m kills the entire process tree on timeout (default),
+             \033[36mkm\033[35m kills just the main process
+             \033[36mkn\033[35m lets it continue running until copyparty is terminated
+
+             \033[36mc0\033[35m show all process output (default)

+             \033[36mc3\033[35m mute all process otput
+            \033[0m
+            except for \033[36mxm\033[0m, only one hook / one action can run at a time,
+            so it's recommended to use the \033[36mf\033[0m flag unless you really need
+            to wait for the hook to finish before continuing (without \033[36mf\033[0m

+# 2023-0129-1842  `v1.6.2`  cors k
+
+[Ellie Goulding - Stay Awake (kors k Hardcore Bootleg).mp3](https://a.ocv.me/pub/demo/music/.bonus/#af-134e597c)
+* 👆 the read-only demo server at https://a.ocv.me/pub/demo/
+
+## breaking changes
+but nothing is affected (that i know of):
+* all requests must pass [cors validation](https://github.com/9001/copyparty#cors)
+  * but they almost definitely did already
+  * sharex and others are OK since they don't supply an `Origin` header
+* [API calls](https://github.com/9001/copyparty/blob/hovudstraum/docs/devnotes.md#http-api) `?delete` and `?move` are now POST instead of GET
+  * not aware of any clients using these
+
+## known issues
+* the document sandbox is a bit laggy and sometimes eats hotkeys
+  * disable it with `--no-sb-md --no-sb-lg` if you trust everyone who has write and/or move access
+
+## new features
+* [event hooks](https://github.com/9001/copyparty/tree/hovudstraum/bin/hooks) -- run programs on new [uploads](https://user-images.githubusercontent.com/241032/215304439-1c1cb3c8-ec6f-4c17-9f27-81f969b1811a.png), renames, deletes
+* [configurable cors](https://github.com/9001/copyparty#cors) (cross-origin resource sharing) behavior; defaults are mostly same as before
+  * `--allow-csrf` disables all csrf protections and makes it intentionally trivial to send authenticated requests from other domains
+* sandboxed readme.md / prologues / epilogues
+  * documents can still run scripts like before, but can no longer tamper with the web-ui / read the login session, so the old advice of `--no-readme` and `--no-logues` is mostly deprecated
+  * unfortunately disables hotkeys while the text has focus + blocks dragdropping files onto that area, oh well
+* password can be provided through http header `PW:` (instead of cookie `cppwd` or or url-param `?pw`)
+* detect network changes (new NICs, IPs) and reconfigure / reannoucne zeroconf
+  * fixes mdns when running as a systemd service and copyparty is started before networking is up
+* add `--freebind` to start listening on IPs before the NIC is up yet (linux-only)
+* per-volume deduplication-control with volflags `hardlink`, `neversymlink`, `copydupes`
+* detect curl and return a [colorful, sortable plaintext](https://user-images.githubusercontent.com/241032/215322619-ea5fd606-3654-40ad-94ee-2bc058647bb2.png) directory listing instead
+* add optional [powered-by-copyparty](https://user-images.githubusercontent.com/241032/215322626-11d1f02b-25f4-45df-a3d9-f8c51354a8eb.png) footnode on the controlpanel
+  * can be disabled with `-nb` or redirected with `--pb-url`
+
+## bugfixes
+* change some API calls (`?delete`, `?move`) from `GET` to `POST`
+  * don't panic! this was safe against authenticated csrf thanks to [SameSite=Lax](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie/SameSite#lax)
+  * `--getmod` restores the GETs if you need the convenience and accept the risks
+* [u2cli](https://github.com/9001/copyparty/blob/hovudstraum/bin/up2k.py) (command-line uploader):
+  * recover from network hiccups
+  * add `-ns` for slow uefi TTYs
+* separate login cookies for http / https
+  * avoids an https login from getting accidentally sent over plaintext
+  * sadly no longer possible to login with internet explorer 4.0 / windows 3.11
+* tar/zip-download of hidden folders
+* unpost filtering was buggy for non-ascii characters
+* moving a deduplicated file on a volume where deduplication was since disabled
+* improved the [linux 6.0.16](https://utcc.utoronto.ca/~cks/space/blog/linux/KernelBindBugIn6016) kernel bug [workaround](https://github.com/9001/copyparty/commit/9065226c3d634a9fc15b14a768116158bc1761ad) because there is similar funk in 5.x

+* macos dualstack thing
+
+## other changes

+# 2023-0112-0515  `v1.5.6`  many hands
+
+hello from warsaw airport (goodbye japan ;_;)
+* read-only demo server at https://a.ocv.me/pub/demo/
+
+## new features
+* multiple upload handshakes in parallel
+  * around **5x faster** when uploading small files
+  * or **50x faster** if the server is on the other side of the planet
+    * just crank up the `parallel uploads` like crazy (max is 64)
+* upload ui: total time and average speed is shown on completion
+
+## bugfixes
+* browser ui didn't allow specifying number of threads for file search
+* dont panic if a digit key is pressed while viewing an image
+* workaround [linux kernel bug](https://utcc.utoronto.ca/~cks/space/blog/linux/KernelBindBugIn6016) causing log spam on dualstack
+  * ~~related issue (also mostly harmless) will be fixed next relese 010770684db95bece206943768621f2c7c27bace~~ 
+    * they fixed it in linux 6.1 so these workarounds will be gone too

+
+## bugfixes
+* thumbnailing could fail if a primitive build of libvips is installed
+* ssdp was wonky on dualstack ipv6
+* mdns could crash on networks with invalid routes

+# 2022-1213-1956  `v1.5.3`  folder-sync + turbo-rust
+
+* read-only demo server at https://a.ocv.me/pub/demo/
+
+## new features
+* one-way folder sync (client to server) using [up2k.py](https://github.com/9001/copyparty/blob/hovudstraum/bin/README.md#up2kpy) `-z --dr`
+  * great rsync alternative when combined with `-e2ds --hardlink` deduplication on the server
+* **50x faster** when uploading small files to HDD, especially SMR
+  * by switching sqlite to WAL which carries a small chance of temporarily forgetting the ~200 most recent uploads if you have a power outage or your OS crashes; see `--help-dbd` if you have `-mtp` plugins which produces metadata you can't afford to lose
+* location-based [reverse-proxying](https://github.com/9001/copyparty/#reverse-proxy) (but it's still recommended to use a dedicated domain/subdomain instead)
+* IPv6 link-local automatically enabled for TCP and zeroconf on NICs without a routable IPv6
+* zeroconf network filters now accept subnets too, for example `--z-on 192.168.0.0/16`
+* `.hist` folders are hidden on windows
+* ux:
+  * more accurate total ETA on upload
+  * sorting of batch-unpost links was unintuitive / dangerous
+  * hotkey `Y` turns files into download links if nothing's selected
+  * option to replace or disable the mediaplayer-toggle mouse cursor with `--mpmc`
+
+## bugfixes
+* WAL probably/hopefully fixes #10 (we'll know in 6 months roughly)
+* repair db inconsistencies (which can happen if terminated during startup)
+* [davfs2](https://wiki.archlinux.org/title/Davfs2) did not approve of the authentication prompt
+* the `connect` button on the control-panel didn't work on phones
+* couldn't specify windows NICs in arguments `--z-on` / `--z-off` and friends
+* ssdp xml escaping for `--zsl` URL
+* no longer possible to accidentally launch multiple copyparty instances on the same port on windows
+
+

+insane ways to use copyparty
+
+
+## wireless keyboard
+
+problem: you wanna control mpv or whatever software from the couch but you don't have a wireless keyboard
+
+"solution": load some custom javascript which renders a virtual keyboard on the upload UI and each keystroke is actually an upload which gets picked up by a dummy metadata parser which forwards the keystrokes into xdotool
+
+[no joke, this actually exists and it wasn't even my idea or handiwork (thx steen)](https://github.com/9001/copyparty/blob/hovudstraum/contrib/plugins/meadup.js)
+
+
+## appxsvc tarpit
+
+problem: `svchost.exe` is using 100% of a cpu core, and upon further inspection (`procmon`) it is `wsappx` desperately trying to install something, repeatedly reading a file named `AppxManifest.xml` and messing with an sqlite3 database
+
+"solution": create a virtual filesystem which is intentionally slow and trick windows into reading it from there instead
+
+* create a file called `AppxManifest.xml` and put something dumb in it
+* serve the file from a copyparty instance with `--rsp-slp=9` so every request will hang for 9 sec
+* `net use m: http://127.0.0.1:3993/`  (mount copyparty using the windows-native webdav client)
+* `mklink /d c:\windows\systemapps\microsoftwindows.client.cbs_cw5n1h2txyewy\AppxManifest.xml m:\AppxManifest.xml`

+# recommendations
+
+* [kodbox](https://github.com/kalcaddle/kodbox) ([review](#kodbox)) appears to be a fantastic alternative if you're not worried about running chinese software, with several advantages over copyparty
+  * but anything you want to share must be moved into the kodbox filesystem
+* [seafile](https://github.com/haiwen/seafile) ([review](#seafile)) and [nextcloud](https://github.com/nextcloud/server) ([review](#nextcloud)) could be decent alternatives if you need something heavier than copyparty
+  * but their [license](https://snyk.io/learn/agpl-license/) is [problematic](https://opensource.google/documentation/reference/using/agpl-policy)
+  * and copyparty is way better at uploads in particular (resumable, accelerated)
+  * and anything you want to share must be moved into the respective filesystems
+* [filebrowser](https://github.com/filebrowser/filebrowser) ([review](#filebrowser)) and [dufs](https://github.com/sigoden/dufs) ([review](#dufs)) are simpler copyparties but with a settings gui
+  * has some of the same strengths of copyparty, being portable and able to work with an existing folder structure
+  * ...but copyparty is better at uploads + some other things

+* `b`/hfs2 runs on linux through wine

+
+* `upload segmenting` = files are sliced into chunks, making it possible to upload files larger than 100 MiB on cloudflare for example
+
+* `upload acceleration` = each file can be uploaded using several TCP connections, which can offer a huge speed boost over huge distances / on flaky connections -- like the good old [download accelerators](https://en.wikipedia.org/wiki/GetRight) except in reverse
+
+* `upload verification` = uploads are checksummed or otherwise confirmed to have been transferred correctly
+
+* `checksums provided` = when downloading a file from the server, the file's checksum is provided for verification client-side
+
+* `cloud storage backend` = able to serve files from (and write to) s3 or similar cloud services; `╱` means the software can do this with some help from `rclone mount` as a bridge
+
+* `a`/copyparty can reject uploaded files (based on complex conditions), for example [by extension](https://github.com/9001/copyparty/blob/hovudstraum/bin/hooks/reject-extension.py) or [mimetype](https://github.com/9001/copyparty/blob/hovudstraum/bin/hooks/reject-mimetype.py)
+* `j`/filebrowser remarks:
+  * can provide checksums for single files on request
+  * can probably do extension/mimetype rejection similar to copyparty
+* `k`/filegator download-as-zip is not streaming; it creates the full zipfile before download can start

+
+* `unmap subfolders` = "shadowing"; mounting a local folder in the middle of an existing filesystem tree in order to disable access below that path
+* `files stored as-is` = uploaded files are trivially readable from the server HDD, not sliced into chunks or in weird folder structures or anything like that
+* `db stored in folder` = filesystem index can be written to a database file inside the folder itself
+* `db stored out-of-tree` = filesystem index can be stored some place else, not necessarily inside the shared folders
+* `existing file tree` = will index any existing files it finds
+* `file action event hooks` = run script before/after upload, move, rename, ...
+* `one-way folder sync` = like rsync, optionally deleting unexpected files at target
+* `full sync` = stateful, dropbox-like sync
+* `curl-friendly ls` = returns a [sortable plaintext folder listing](https://user-images.githubusercontent.com/241032/215322619-ea5fd606-3654-40ad-94ee-2bc058647bb2.png) when curled
+* `curl-friendly upload` = uploading with curl is just `curl -T some.bin http://.../`
+* `a`/copyparty remarks:
+  * one-way folder sync from local to server can be done efficiently with [up2k.py](https://github.com/9001/copyparty/blob/hovudstraum/bin/up2k.py), or with webdav and conventional rsync
+  * can hot-reload config files (with just a few exceptions)
+  * can set per-folder permissions if that folder is made into a separate volume, so there is configuration overhead
+  * [event hooks](https://github.com/9001/copyparty/tree/hovudstraum/bin/hooks) ([discord](https://user-images.githubusercontent.com/241032/215304439-1c1cb3c8-ec6f-4c17-9f27-81f969b1811a.png), [desktop](https://user-images.githubusercontent.com/241032/215335767-9c91ed24-d36e-4b6b-9766-fb95d12d163f.png)) inspired by filebrowser, as well as the more complex [media parser](https://github.com/9001/copyparty/tree/hovudstraum/bin/mtag) alternative
+  * upload history can be visualized using [partyjournal](https://github.com/9001/copyparty/blob/hovudstraum/bin/partyjournal.py)
+* `k`/filegator remarks:
+  * `per-* permissions` -- can limit a user to one folder and its subfolders
+  * `unmap subfolders` -- can globally filter a list of paths

+
+# reviews
+
+* ✅ are advantages over copyparty
+* ⚠️ are disadvantages
+
+## [copyparty](https://github.com/9001/copyparty)
+* resumable uploads which are verified server-side
+* upload segmenting allows for potentially much faster uploads on some connections, and terabyte-sized files even on cloudflare
+  * both of the above are surprisingly uncommon features
+* very cross-platform (python, no dependencies)
+
+## [hfs2](https://github.com/rejetto/hfs2)
+* the OG, the legend
+* ⚠️ uploads not resumable / accelerated / integrity-checked
+  * ⚠️ on cloudflare: max upload size 100 MiB
+* ⚠️ windows-only
+* ✅ config GUI
+* vfs with gui config, per-volume permissions
+* starting to show its age, hence the rewrite:
+
+## [hfs3](https://www.rejetto.com/hfs/)
+* nodejs; cross-platform
+* vfs with gui config, per-volume permissions
+* still early development, let's revisit later
+
+## [nextcloud](https://github.com/nextcloud/server)
+* php, mariadb
+* ⚠️ [isolated on-disk file hierarchy] in per-user folders
+  * not that bad, can probably be remedied with bindmounts or maybe symlinks
+* ⚠️ uploads not resumable / accelerated / integrity-checked
+  * ⚠️ on cloudflare: max upload size 100 MiB
+* ⚠️ no write-only / upload-only folders
+* ⚠️ http/webdav only; no ftp, zeroconf
+* ⚠️ less awesome music player
+* ⚠️ doesn't run on android or ipads
+* ✅ great ui/ux
+* ✅ config gui
+* ✅ apps (android / iphone)
+  * copyparty: android upload-only app
+* ✅ more granular permissions (per-file)
+* ✅ search: fulltext indexing of file contents
+* ✅ webauthn passwordless authentication
+
+## [seafile](https://github.com/haiwen/seafile)
+* c, mariadb
+* ⚠️ [isolated on-disk file hierarchy](https://manual.seafile.com/maintain/seafile_fsck/), incompatible with other software
+  * *much worse than nextcloud* in that regard
+* ⚠️ uploads not resumable / accelerated / integrity-checked
+  * ⚠️ on cloudflare: max upload size 100 MiB
+* ⚠️ no write-only / upload-only folders
+* ⚠️ http/webdav only; no ftp, zeroconf
+* ⚠️ less awesome music player
+* ⚠️ doesn't run on android or ipads
+* ✅ great ui/ux
+* ✅ config gui
+* ✅ apps (android / iphone)
+  * copyparty: android upload-only app
+* ✅ more granular permissions (per-file)
+* ✅ search: fulltext indexing of file contents
+
+## [rclone](https://github.com/rclone/rclone)
+* nice standalone c program
+* ⚠️ uploads not resumable / accelerated / integrity-checked
+  * ⚠️ on cloudflare: max upload size 100 MiB
+* ⚠️ no web-ui, just a server / downloader / uploader utility
+* ✅ works with almost any protocol, cloud provider
+  * ⚠️ copyparty's webdav server is slightly faster
+
+## [dufs](https://github.com/sigoden/dufs)
+* rust; cross-platform (windows, linux, macos)
+* ⚠️ uploads not resumable / accelerated / integrity-checked
+  * ⚠️ on cloudflare: max upload size 100 MiB
+* ⚠️ doesn't support crazy filenames
+* ✅ per-url access control (copyparty is per-volume)
+* basic but really snappy ui
+* upload, rename, delete, ... see feature matrix
+
+## [chibisafe](https://github.com/chibisafe/chibisafe)
+* nodejs; recommends docker
+* *it has upload segmenting!*
+  * ⚠️ but uploads are still not resumable / accelerated / integrity-checked
+* ⚠️ not portable
+* ⚠️ isolated on-disk file hierarchy, incompatible with other software
+* ⚠️ http/webdav only; no ftp or zeroconf
+* ✅ pretty ui
+* ✅ control panel for server settings and user management
+* ✅ user registration
+* ✅ searchable image tags; delete by tag
+* ✅ browser extension to upload files to the server
+* ✅ reject uploads by file extension
+  * copyparty: can reject uploads [by extension](https://github.com/9001/copyparty/blob/hovudstraum/bin/hooks/reject-extension.py) or [mimetype](https://github.com/9001/copyparty/blob/hovudstraum/bin/hooks/reject-mimetype.py) using plugins
+* ✅ token auth (api keys)
+

+  * copyparty: can reject uploads [by extension](https://github.com/9001/copyparty/blob/hovudstraum/bin/hooks/reject-extension.py) or [mimetype](https://github.com/9001/copyparty/blob/hovudstraum/bin/hooks/reject-mimetype.py) using plugins
+* ✅ can use S3 as storage backend; copyparty relies on rclone-mount for that
+* ✅ custom 404 pages
+
+## [linx](https://github.com/ZizzyDizzyMC/linx-server/)
+* originally [andreimarcu/linx-server](https://github.com/andreimarcu/linx-server) but development has ended
+* ⚠️ uploads not resumable / accelerated / integrity-checked
+  * ⚠️ on cloudflare: max upload size 100 MiB
+* some of its unique features have been added to copyparty as former linx users have migrated
+  * file expiration timers, filename randomization
+* ✅ password-protected files
+  * copyparty: password-protected folders + filekeys to skip the folder password seem to cover most usecases
+* ✅ file deletion keys
+* ✅ download files as torrents
+* ✅ remote uploads (send a link to the server and it downloads it)
+  * copyparty: available as [a plugin](https://github.com/9001/copyparty/blob/hovudstraum/bin/hooks/wget.py)
+* ✅ can use S3 as storage backend; copyparty relies on rclone-mount for that
+
+
+# briefly considered
+* [pydio](https://github.com/pydio/cells): python/agpl3, looks great, fantastic ux -- but needs mariadb, systemwide install
+* [gossa](https://github.com/pldubouilh/gossa): go/mit, minimalistic, basic file upload, text editor, mkdir and rename (no delete/move)
+* [h5ai](https://larsjung.de/h5ai/): php/mit, slick ui, image viewer, directory tree, no upload feature
