+## 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
+* 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.

+  * if one or more files are selected for sharing, they are placed into a virtual folder
+  * more appropriate password UI for accessing protected shares
+  * human-readable timestamps in shares listing
+* u2c (commandline uploader): support multiple exclusion patterns f356faa2
+
+## bugfixes

+* remove confusing logmessage when downloading a zerobyte file 9f034d9c
+* shares: 7ff46966
+  * fix crash if the root volume is unmapped
+  * log-spam on config reload

+
+## new features
+
+* #92 users can change their own passwords 83fb569d 00da7440
+  * this feature is default-disabled; see [readme](https://github.com/9001/copyparty#user-changeable-passwords)
+* #84 share files/folders by creating a temporary url 7c2beba5
+  * inspired by other file servers; click the share-button to create a link like `example.com/share/enkz8g374o8g`
+    * primary usecase is to sneak past authentication services (see issue description)
+  * the create-share UI has options to accept uploads into the share, and/or set expiration time
+  * this feature is default-disabled; see [readme](https://github.com/9001/copyparty#shares)
+
+## bugfixes
+
+* #93 fixes for vproxy / location-based / not-vhost-based reverse-proxying 0b46b1a6
+  * using `--rp-loc` to reverse-proxy from a subfolder made some UI stuff break
+* listening on unix-sockets: 687df2fa
+  * fix `x-forwarded-for` support, and avoid a possible container-specific collision
+  * new syntax which allows setting unix-permissions and unix-group

+# 2024-0813-0008  `v1.13.8`  hook into place
+
+## new features
+
+* #86 intentional side-effects from hooks 6c94a63f
+  * use hooks (plugins) to conditionally move uploads into another folder depending on filename, extension, uploader ip/name, file contents, ...
+  * hooks can create additional files and tell copyparty to index them immediately, or delete an existing file based on some condition
+  * only one example so far though, [reloc-by-ext](https://github.com/9001/copyparty/tree/hovudstraum/bin/hooks#before-upload) which was a feature-request to dodge [sharex#3992](https://github.com/ShareX/ShareX/issues/3992)
+* listen on unix-sockets ee9aad82
+  * `-i unix:/tmp/party.sock` stops listening on TCP ports entirely, and only listens on that unix-socket
+  * can be combined with regular sockets, `-i 127.0.0.1,unix:/tmp/a.sock`
+  * kinda buggy for now (need to `--xff-src=any` and doesn't let you set socket-perms yet), will be fixed in next ver
+  * makes it 10% faster, but more importantly offers tighter access control behind reverse-proxies
+    * inspired by https://www.oligo.security/blog/0-0-0-0-day-exploiting-localhost-apis-from-the-browser
+* up2k stitching:
+  * more optimal stitch sizes for max throughput across connections c862ec1b
+  * improve fat32 compatibility 373194c3
+* new option `--js-other` to load custom javascript dbd42bc6
+  * `--js-browser` affects the filebrowser page, `--js-other` does all the others
+  * endless possibilities, such as [adding a login-banner](https://github.com/9001/copyparty/blob/hovudstraum/contrib/plugins/banner.js) which [looks like this](https://github.com/user-attachments/assets/8ae8e087-b209-449c-b08d-74e040f0284b)
+* list detected optional dependencies on startup 3db117d8
+  * hopefully reduces the guesswork / jank factor by a tiny bit
+
+## bugfixes
+
+* up2k stitching:
+  * put the request headers on a diet so they fit through more reverse-proxies 0da719f4
+* fix deadlock on s390x (IBM mainframes) 250c8c56
+
+## other changes
+
+* add flags to disengage [features](https://github.com/9001/copyparty/tree/hovudstraum#feature-chickenbits) and [dependencies](https://github.com/9001/copyparty/tree/hovudstraum#dependency-chickenbits) in case they cause trouble 72361c99
+* optimizations
+  * 6% faster on average d5c9c8eb
+  * docker: reduce ram usage 98ffaadf
+  * python2: reduce ram usage ebb19818
+* docker: add [portainer howto](https://github.com/9001/copyparty/blob/hovudstraum/docs/examples/docker/portainer.md) e136231c
+* update deps ca001c85
+  * pyftpdlib 1.5.10

+# 2024-0729-2028  `v1.13.6`  not that big
+
+## new features
+
+* up2k.js: set clientside timeouts on http connections during upload 85e54980
+  * some reverse-proxy setups could cause uploads to hang indefinitely by eating requests; should recover nicely now
+* audio-player shows statustext while loading 662541c6
+* [bsod theme](https://github.com/9001/copyparty/tree/hovudstraum/contrib/themes) [(live demo)](https://cd.ocv.me/c/) 15ddcf53
+
+## bugfixes
+
+* fix bugs in the [long-distance upload optimizations](https://github.com/9001/copyparty/releases/tag/v1.13.5) in the previous version:
+  * up2k.js didn't necessarily use the expected chunksize when stitching 225bd80e
+  * u2c (commandline uploader): 8916bce3
+    * use the correct chunksize instead of overshooting like crazy
+    * could crash on exit if `-z` was enabled (so basically harmless)
+    * the "time spent uploading" statustext that was printed on exit could multiply by `-j` and exceed walltime
+* misc ux 9bb6e0dc
+  * don't accept hotkeys until it's safe to do so
+  * improve messages regarding the [firefox crash](https://bugzilla.mozilla.org/show_bug.cgi?id=1790500)
+  * keep more console logs in memory (easier to debug)
+  * fix wordwrap in messageboxes on firefox a19a0fa9
+
+## other changes
+
+* changed the `xm` / "on message" [hook examples](https://github.com/9001/copyparty/tree/hovudstraum/bin/hooks#on-message) to reject users without write-access 99edba4f
+* docker images were rebuilt on 2024-08-02, 23:30 UTC with new optimizations: 98ffaadf
+  * 😃 RAM usage decreased by `5-6 MiB` for most flavors; `10 MiB` for dj/iv
+  * 😕 image size grew by `4 MiB` (min), `6 MiB` (ac/im/iv), `9 MiB` (dj)
+  * 😃 startup time reduced to about half
+  * and avoids a deadlock on IBM mainframes
+* updated comparison to other software 6b54972e
+  * `hfs2` is dead, `hfs3` and `filebrowser` improved

+
+## 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)
