 ### at home
 make it accessible over the internet  by starting a [cloudflare quicktunnel](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/do-more-with-tunnels/trycloudflare/) like so:
 first download [cloudflared](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/downloads/) and then start the tunnel with `cloudflared tunnel --url http://127.0.0.1:3923`
 as the tunnel starts, it will show a URL which you can share to let anyone browse your stash or upload files to you

 ## shares
 share a file or folder by creating a temporary link
 when enabled in the server settings (`--shr`), click the bottom-right `share` button to share the folder you're currently in, or alternatively:
 * select a folder first to share that folder instead
 * select one or more files to share only those files
 this feature was made with [identity providers](#identity-providers) in mind -- configure your reverseproxy to skip the IdP's access-control for a given URL prefix and use that to safely share specific files/folders sans the usual auth checks
 when creating a share, the creator can choose any of the following options:
 * password-protection
 * expire after a certain time; `0` or blank means infinite
 * allow visitors to upload (if the user who creates the share has write-access)
 semi-intentional limitations:
 * cleanup of expired shares only works when global option `e2d` is set, and/or at least one volume on the server has volflag `e2d`
 * only folders from the same volume are shared; if you are sharing a folder which contains other volumes, then the contents of those volumes will not be available
 * related to [IdP volumes being forgotten on shutdown](https://github.com/9001/copyparty/blob/hovudstraum/docs/idp.md#idp-volumes-are-forgotten-on-shutdown), any shares pointing into a user's IdP volume will be unavailable until that user makes their first request after a restart
 * no option to "delete after first access" because tricky
  * when linking something to discord (for example) it'll get accessed by their scraper and that would count as a hit
  * browsers wouldn't be able to resume a broken download unless the requester's IP gets allowlisted for X minutes (ref. tricky)
 specify `--shr /foobar` to enable this feature; a toplevel virtual folder named `foobar` is then created, and that's where all the shares will be served from
 * you can name it whatever, `foobar` is just an example
 * if you're using config files, put `shr: /foobar` inside the `[global]` section instead
 users can delete their own shares in the controlpanel, and a list of privileged users (`--shr-adm`) are allowed to see and/or delet any share on the server
 after a share has expired, it remains visible in the controlpanel for `--shr-rt` minutes (default is 1 day), and the owner can revive it by extending the expiration time there
 **security note:** using this feature does not mean that you can skip the [accounts and volumes](#accounts-and-volumes) section -- you still need to restrict access to volumes that you do not intend to share with unauthenticated users! it is not sufficient to use rules in the reverseproxy to restrict access to just the `/share` folder.

 ## file deduplication
 enable symlink-based upload deduplication  globally with `--dedup` or per-volume with volflag `dedup`
 by default, when someone tries to upload a file that already exists on the server, the upload will be politely declined, and the server will copy the existing file over to where the upload would have gone
 if you enable deduplication with `--dedup` then it'll create a symlink instead of a full copy, thus reducing disk space usage
 * on the contrary, if your server is hooked up to s3-glacier or similar storage where reading is expensive, and you cannot use `--safe-dedup=1` because you have other software tampering with your files, so you want to entirely disable detection of duplicate data instead, then you can specify `--no-clone` globally or `noclone` as a volflag
 **warning:** when enabling dedup, you should also:
 * enable indexing with `-e2dsa` or volflag `e2dsa` (see [file indexing](#file-indexing) section below); strongly recommended
 * ...and/or `--hardlink-only` to use hardlink-based deduplication instead of symlinks; see explanation below
 it will not be safe to rename/delete files if you only enable dedup and none of the above; if you enable indexing then it is not *necessary* to also do hardlinks (but you may still want to)
 by default, deduplication is done based on symlinks (symbolic links); these are tiny files which are pointers to the nearest full copy of the file
 you can choose to use hardlinks instead of softlinks, globally with `--hardlink-only` or volflag `hardlinkonly`;
 advantages of using hardlinks:
 * hardlinks are more compatible with other software; they behave entirely like regular files
 * you can safely move and rename files using other file managers
  * symlinks need to be managed by copyparty to ensure the destinations remain correct
 advantages of using symlinks (default):
 * each symlink can have its own last-modified timestamp, but a single timestamp is shared by all hardlinks
 * symlinks make it more obvious to other software that the file is not a regular file, so this can be less dangerous
  * hardlinks look like regular files, so other software may assume they are safe to edit without affecting the other copies
 **warning:** if you edit the contents of a deduplicated file, then you will also edit all other copies of that file! This is especially surprising with hardlinks, because they look like regular files, but that same file exists in multiple locations
 global-option `--xlink` / volflag `xlink` additionally enables deduplication across volumes, but this is probably buggy and not recommended

 ### dirkeys
 share specific folders in a volume  without giving away full read-access to the rest -- the visitor only needs the `g` (get) permission to view the link
 volflag `dk` generates dirkeys (per-directory accesskeys) for all folders, granting read-access to that folder; by default only that folder itself, no subfolders
 volflag `dky` disables the actual key-check, meaning anyone can see the contents of a folder where they have `g` access, but not its subdirectories
 * `dk` + `dky` gives the same behavior as if all users with `g` access have full read-access, but subfolders are hidden files (as if their names start with a dot), so `dky` is an alternative to renaming all the folders for that purpose, maybe just for some users
 volflag `dks` lets people enter subfolders as well, and also enables download-as-zip/tar
 if you enable dirkeys, it is probably a good idea to enable filekeys too, otherwise it will be impossible to hotlink files from a folder which was accessed using a dirkey
 dirkeys are generated based on another salt (`--dk-salt`) + filesystem-path and have a few limitations:
 * the key does not change if the contents of the folder is modified
  * if you need a new dirkey, either change the salt or rename the folder

 you can optionally specify another location by adding a whitespace

 # event hooks
 on writing your own [hooks](../README.md#event-hooks)
 ## hook effects
 hooks can cause intentional side-effects,  such as redirecting an upload into another location, or creating+indexing additional files, or deleting existing files, by returning json on stdout
 * `reloc` can redirect uploads before/after uploading has finished, based on filename, extension, file contents, uploader ip/name etc.
 * `idx` informs copyparty about a new file to index as a consequence of this upload
 * `del` tells copyparty to delete an unrelated file by vpath
 for these to take effect, the hook must be defined with the `c1` flag; see example [reloc-by-ext](https://github.com/9001/copyparty/blob/hovudstraum/bin/hooks/reloc-by-ext.py)
 a subset of effect types are available for a subset of hook types,
 * most hook types (xbu/xau/xbr/xar/xbd/xad/xm) support `idx` and `del` for all http protocols (up2k / basic-uploader / webdav), but not ftp/tftp/smb
 * most hook types will abort/reject the action if the hook returns nonzero, assuming flag `c` is given, see examples [reject-extension](https://github.com/9001/copyparty/blob/hovudstraum/bin/hooks/reject-extension.py) and [reject-mimetype](https://github.com/9001/copyparty/blob/hovudstraum/bin/hooks/reject-mimetype.py)
 * `xbu` supports `reloc` for all http protocols (up2k / basic-uploader / webdav), but not ftp/tftp/smb
 * `xau` supports `reloc` for basic-uploader / webdav only, not up2k or ftp/tftp/smb
  * so clients like sharex are supported, but not dragdrop into browser
 to trigger indexing of files `/foo/1.txt` and `/foo/bar/2.txt`, a hook can `print(json.dumps({"idx":{"vp":["/foo/1.txt","/foo/bar/2.txt"]}}))` (and replace "idx" with "del" to delete instead)
 * note: paths starting with `/` are absolute URLs, but you can also do `../3.txt` relative to the destination folder of each uploaded file

 the following setup appears to work (copyparty starts, accepts uploads, is able to persist config)
 tested on debian 12 using [portainer-ce](https://docs.portainer.io/start/install-ce/server/docker/linux) with [docker-ce](https://docs.docker.com/engine/install/debian/) as root (not rootless)
 before making the container, first `mkdir /etc/copyparty /srv/pub` which will be bind-mounts into the container
 > both `/etc/copyparty` and `/srv/pub` are examples; you can change them if you'd like
 put your copyparty config files directly into `/etc/copyparty` and the files to share inside `/srv/pub`
 on first startup, copyparty will create a subfolder inside `/etc/copyparty` called `copyparty` where it puts some runtime state; for example replacing `/etc/copyparty/copyparty/cert.pem` with another TLS certificate is a quick and dirty way to get valid HTTPS (if you really want copyparty to handle that and not a reverse-proxy)
 ## in portainer:
 ```
 environments -> local -> containers -> add container:
       name = copyparty-ac
   registry = docker hub
      image = copyparty/ac
 always pull = no
 manual network port publishing:
  3923 to 3923 [TCP]
 advanced -> command & logging:
  console = interactive & tty
 advanced -> volumes -> map additional volume:
  container = /cfg  [Bind]
  host = /etc/copyparty  [Writable]
 advanced -> volumes -> map additional volume:
  container = /w  [Bind]
  host = /srv/pub  [Writable]
 ```
 notes:
 * `/cfg` is where copyparty expects to find its config files; `/etc/copyparty` is just an example mapping to that
 * `/w` is where copyparty expects to find the folder to share; `/srv/pub` is just an example mapping to that
 * the volumes must be bind-mounts to avoid permission issues (or so the theory goes)

 # recipe for building an exe with nuitka (extreme jank edition)
-#
+
-# NOTE: win7 and win10 builds both work on win10 but
+NOTE: copyparty runs SLOWER when compiled with nuitka;
-#   on win7 they immediately c0000005 in kernelbase.dll
+  just use copyparty-sfx.py and/or pyinstaller instead
-#
+
-# first install python-3.6.8-amd64.exe
+  ( the sfx and the pyinstaller EXEs are equally fast if you
-#   [x] add to path
+  have the latest jinja2 installed, but the older jinja that
-#
+  comes bundled with the sfx is slightly faster yet )
  roughly, copyparty-sfx.py is 6% faster than copyparty.exe
  (win10-pyinstaller), and copyparty.exe is 10% faster than
  nuitka, making copyparty-sfx.py 17% faster than nuitka
 NOTE: every time a nuitka-compiled copyparty.exe is launched,
  it will show the windows firewall prompt since nuitka will
  pick a new unique location in %TEMP% to unpack an exe into,
  unlike pyinstaller which doesn't fork itself on startup...
  might be fixable by configuring nuitka differently, idk
 NOTE: nuitka EXEs are larger than pyinstaller ones;
  a minimal nuitka build of just the sfx (with its bundled
  dependencies) was already the same size as the pyinstaller
  copyparty.exe which also includes Mutagen and Pillow
 NOTE: nuitka takes a lot longer to build than pyinstaller
  (due to actual compilation of course, but still)
 NOTE: binaries built with nuitka cannot run on windows7,
  even when compiled with python 3.6 on windows 7 itself
 NOTE: `--python-flags=-m` is the magic sauce to
  correctly compile `from .util import Daemon`
  (which otherwise only explodes at runtime)
 NOTE: `--deployment` doesn't seem to affect performance

 none of this is version-specific but doing absolute links just in case

@@ -47,3 +47,44 @@ and if you want to have a monospace font in the fancy markdown editor, do this:
 NB: `<textarea id="mt">` and `<div id="mtr">` in the regular markdown editor must have the same font; none of the suggestions above will cause any issues but keep it in mind if you're getting creative
 # `<head>`
 to add stuff to the html `<head>`, for example a css `<link>` or `<meta>` tags, use either the global-option `--html-head` or the volflag `html_head`
 if you give it the value `@ASDF` it will try to open a file named ASDF and send the text within
 if the value starts with `%` it will assume a jinja2 template and expand it; the template has access to the `HttpCli` object through a property named `this` as well as everything in `j2a` and the stuff added by `self.j2s`; see [browser.html](https://github.com/9001/copyparty/blob/hovudstraum/copyparty/web/browser.html) for inspiration or look under the hood in [httpcli.py](https://github.com/9001/copyparty/blob/hovudstraum/copyparty/httpcli.py)
 # translations
 add your own translations by using the english or norwegian one from `browser.js` as a template
 the easy way is to open up and modify `browser.js` in your own installation; depending on how you installed copyparty it might be named `browser.js.gz` instead, in which case just decompress it, restart copyparty, and start editing it anyways
 you will be delighted to see inline html in the translation strings; to help prevent syntax errors, there is [a very jank linux script](https://github.com/9001/copyparty/blob/hovudstraum/scripts/tlcheck.sh) which is slightly better than nothing -- just beware the false-positives, so even if it complains it's not necessarily wrong/bad
 if you're running `copyparty-sfx.py` then you'll find it at `/tmp/pe-copyparty.1000/copyparty/web` (on linux) or `%TEMP%\pe-copyparty\copyparty\web` (on windows)
 * make sure to keep backups of your work religiously! since that location is volatile af
 ## translations (docker-friendly)
 if editing `browser.js` is inconvenient in your setup, for example if you're running in docker, then you can instead do this:
 * if you have python, go to the `scripts` folder and run `./tl.py fra Français` to generate a `tl.js` which is perfect for translating to French, using the three-letter language code `fra`
  * if you do not have python, you can also just grab `tl.js` from the scripts folder, but I'll probably forget to keep that up to date... and then you'll have to find/replace all `"eng"` and `Ls.eng` to your three-letter language code
 * put your `tl.js` inside a folder that is being shared by your copyparty, preferably the webroot
 * run copyparty with the argument `--html-head='<script src="/tl.js"></script>'`
  * if you placed `tl.js` in the webroot then you're all good, but if you put it somewhere else then change `/tl.js` accordingly
  * if you are running copyparty with config files, you can do this:
    ```yaml
 	[global]
 	  html-head: <script src="/tl.js"></script>
 	```
 you can now edit `tl.js` and press CTRL-SHIFT-R in the browser to see your changes take effect as you go
 if you want to contribute your translation back to the project (please do!) then you'll want to...
 * grab all of the text inside your `var tl_cpanel = {` and add it to the translations inside `copyparty/web/splash.js` in the repo
 * and the text inside your `var tl_browser = {` and add that to the translations inside `copyparty/web/browser.js` in the repo
