+## 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.

+
+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

+
+## recent important news
+
+* [v1.15.0 (2024-09-08)](https://github.com/9001/copyparty/releases/tag/v1.15.0) changed upload deduplication to be default-disabled
+* [v1.14.3 (2024-08-30)](https://github.com/9001/copyparty/releases/tag/v1.14.3) fixed a bug that was introduced in v1.13.8 (2024-08-13); this bug could lead to **data loss** -- see the v1.14.3 release-notes for details
+
+# upload deduplication now disabled by default
+
+because many people found the behavior surprising. This also makes it easier to use copyparty together with other software, since there is no risk of damage to symlinks if there are no symlinks to damage
+
+to enable deduplication, use either `--dedup` (old-default, symlink-based), or `--hardlink` (will use hardlinks when possible), or `--hardlink-only` (disallow symlinks). To choose the approach that fits your usecase, see [file deduplication](https://github.com/9001/copyparty#file-deduplication) in the readme
+
+verification of local file consistency was also added; this happens when someone uploads a dupe, to ensure that no other software has modified the local file since last reindex. This unfortunately makes uploading of duplicate files much slower, and can be disabled with `--safe-dedup 1` if you know that only copyparty will be modifying the filesystem
+
+## new features
+
+* dedup improvements:
+  * verify consistency of local files before using them as dedup source 6e671c52
+    * if a local file has been altered by other software since the last reindexing, then this will now be detected
+* u2c (commandline uploader): add mode to print hashes of local files 08848be7
+  * if you've lost a file but you know its `wark` (file identifier), you can now use u2c.exe to scan your whole filesystem for it: `u2c - .`
+* #96 use local timezone in log messages b599fbae
+
+## bugfixes
+
+* dedup fixes:
+  * symlinks could break if moved/renamed inside a volume where deduplication was disabled after some files within had already been deduplicated 4401de04
+  * when moving/renaming, only consider symlinks between volumes if `xlink` volflag is set b5ad9369
+* database consistency verifier (`-e2vp`):

+
+# important bugfix ☢️
+
+this version fixes a file deduplication bug which was introduced in [v1.13.8](https://github.com/9001/copyparty/releases/tag/v1.13.8), released 2024-08-13
+
+its worst-case outcome is **loss of data** in the following scenario:
+* someone uploads a file into a folder where that filename is already taken, but the file contents are different, and the server already has a copy of that new file elsewhere under a different name
+
+specific example:
+* the server has two existing files, `logo.png` and `logo-v2.png`, in the same volume but not necessarily in the same folder, and those files contain different data
+* you have a local copy of `logo-v2.png` on your laptop, but your local filename is `logo.png`
+* you upload your local `logo.png` onto the server, into the same folder as the server's `logo.png`
+* because the files contain different data, the server accidentally replaces the contents of `logo.png` with your version
+
+if you have been using the database feature (globally with `-e2dsa` or volflag `e2ds`), and you suspect you may have hit this bug, then it is a good idea to make a backup of the up2k databases for all your volumes (the files with names starting with `up2k.db`) before restarting copyparty and before you do anything else, especially if you do not have serverlogs from far back in time -- if you have either the databases and/or the serverlogs, then it is possible to identify replaced files with some manual work
+
+you can check if you hit the bug using one of the following two approaches:
+* if your OS has the [gnu find](https://linux.die.net/man/1/find) command, do a search for empty files with `find -type f -size 0`
+* using copyparty (any OS), do the following steps:
+  * make sure that reindex-on-startup is enabled; either globally with `-e2dsa` or volflag `e2ds`
+  * then install this new copyparty version
+  * click the search tab `[🔎]` and type the number `0` into the `maximum MiB` textbox
+
+if you find any empty files with a filename that indicates it was autogenerated to avoid a name collision, for example `logo.png-1725040569.239207-kbt0xteO.png`, and the value of the number after `logo.png` is larger than `1723507200` (unixtime for 2024-08-13), then this indicates that `logo.png` may have been replaced by another upload
+
+if you have the serverlogs from when the original upload of `logo.png` was made, then this can be used to identify the original contents of the file that was replaced, and to look for other copies. Please get in touch on the discord for assistance if necessary

+
+* #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

+  * u2c (commandline uploader): 8916bce3
+    * use the correct chunksize instead of overshooting like crazy
+    * could crash on exit if `-z` was enabled (so basically harmless)

+* "medialinks"; instead of the usual hotlink, the basic-uploader (as used by sharex and such) can return a link that opens the file in the media viewer c9281f89
+  * enable for all uploads with volflag `medialinks`, or just for one upload by adding `?media` to the post url
+* thumbnails are now fully compatible with dirkeys/filekeys 52e06226
+* `--th-covers` will respect filename order, selecting the first matching filename as the folder thumbnail 1cdb1702
+* new hook: [bittorrent downloader](https://github.com/9001/copyparty/tree/hovudstraum/bin/hooks#on-message) bd3b3863 803e1565
+* hooks: d749683d
+  * can be restricted to only run when user has specific permissions

+
+* race-the-beam (downloading an unfinished upload) could get interrupted near the end, requiring a manual resume in the browser's download manager to finish f37187a0
+* ftp-server: when accessing the root folder of servers without a root folder, it could mention inaccessible folders 84e8e1dd
+* ftp-server: uploads will automatically replace existing files if user has delete perms 0a9f4c60
+  * windows 2000 expects this behavior, otherwise it'll freak out and delete stuff and then not actually upload it, nice
+  * new option `--ftp-no-ow` restores old default behavior of rejecting upload if target filename exists
+* music player:
+  * stop trying to recover from a corrupted file if the user already fixed it manually 55a011b9

+
+* optimization for large amounts (700+) of tcp connections / clients 07b2bf11

+* fix mimetype detection for uppercase file extensions 565daee9
+* when clicking a `.ts` file in the gridview, don't open it as text 925c7f0a
+  * ...as it's probably an mpeg transport-stream, not a typescript file
+* be less aggressive in dropping volume caches e396c5c2
+  * very minor performance gain, only really relevant if you're doing something like burning a copyparty volume onto a CD
+  * previously, adding or removing any volume at all was enough to drop covers cache for all volumes; now this only happens if an intersecting volume is added/removed

+## other changes

+* opengraph: add the full filename as url suffix 5c1e2390

+
+## 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

 # recipe for building an exe with nuitka (extreme jank edition)
-#
-# NOTE: win7 and win10 builds both work on win10 but
-#   on win7 they immediately c0000005 in kernelbase.dll
-#
-# first install python-3.6.8-amd64.exe
-#   [x] add to path
-#
+
+NOTE: copyparty runs SLOWER when compiled with nuitka;
+  just use copyparty-sfx.py and/or pyinstaller instead
+
+  ( the sfx and the pyinstaller EXEs are equally fast if you
+  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

@@ -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

 * [pydio](https://github.com/pydio/cells): python/agpl3, looks great, fantastic ux -- but needs mariadb, systemwide install
