+really tho, send a PR or an issue or whatever, all appreciated, anything goes, just behave aight 👍👍
+
+but to be more specific,
+
+
+# contribution ideas
+
+
+## documentation
+
+I think we can agree that the documentation leaves a LOT to be desired. I've realized I'm not exactly qualified for this 😅 but maybe the [soon-to-come setup GUI](https://github.com/9001/copyparty/issues/57) will make this more manageable. The best documentation is the one that never had to be written, right? :> so I suppose we can give this a wait-and-see approach for a bit longer.
+
+
+## crazy ideas & features
+
+assuming they won't cause too much problems or side-effects :> 
+
+i think someone was working on a way to list directories over DNS for example...
+
+if you wanna have a go at coding it up yourself then maybe mention the idea on discord before you get too far, otherwise just go nuts 👍
+
+
+## others
+
+aside from documentation and ideas, some other things that would be cool to have some help with is:
+
+* **translations** -- the copyparty web-UI has translations for english and norwegian at the top of [browser.js](https://github.com/9001/copyparty/blob/hovudstraum/copyparty/web/browser.js); if you'd like to add a translation for another language then that'd be welcome! and if that language has a grammar that doesn't fit into the way the strings are assembled, then we'll fix that as we go :>
+
+* **UI ideas** -- at some point I was thinking of rewriting the UI in react/preact/something-not-vanilla-javascript, but I'll admit the comfiness of not having any build stage combined with raw performance has kinda convinced me otherwise :p but I'd be very open to ideas on how the UI could be improved, or be more intuitive.
+
+* **docker improvements** -- I don't really know what I'm doing when it comes to containers, so I'm sure there's a *huge* room for improvement here, mainly regarding how you're supposed to use the container with kubernetes / docker-compose / any of the other popular ways to do things. At some point I swear I'll start learning about docker so I can pick up clach04's [docker-compose draft](https://github.com/9001/copyparty/issues/38) and learn how that stuff ticks, unless someone beats me to it!
+
+* **packaging** for various linux distributions -- this could either be as simple as just plopping the sfx.py in the right place and calling that from systemd (the archlinux package [originally did this](https://github.com/9001/copyparty/pull/18)); maybe with a small config-file which would cause copyparty to load settings from `/etc/copyparty.d` (like the [archlinux package](https://github.com/9001/copyparty/tree/hovudstraum/contrib/package/arch) does with `copyparty.conf`), or it could be a proper installation of the copyparty python package into /usr/lib or similar (the archlinux package [eventually went for this approach](https://github.com/9001/copyparty/pull/26))
+
+  * [fpm](https://github.com/jordansissel/fpm) can probably help with the technical part of it, but someone needs to handle distro relations :-)
+
+* **software integration** -- I'm sure there's a lot of usecases where copyparty could complement something else, or the other way around, so any ideas or any work in this regard would be dope. This doesn't necessarily have to be code inside copyparty itself;
+
+  * [hooks](https://github.com/9001/copyparty/tree/hovudstraum/bin/hooks) -- these are small programs which are called by copyparty when certain things happen (files are uploaded, someone hits a 404, etc.), and could be a fun way to add support for more usecases
+
+  * [parser plugins](https://github.com/9001/copyparty/tree/hovudstraum/bin/mtag) -- if you want to have copyparty analyze and index metadata for some oddball file-formats, then additional plugins would be neat :>

+# 2023-1208-2133  `v1.9.27`  another dedup bug
+
+so [v1.9.26](https://github.com/9001/copyparty/releases/tag/v1.9.26) fixed how moving a symlink could break other related symlinks, and then it turns out symlinks themselves could also die when moving them to another location, and somehow nobody encountered any of these until now... surely there are no more deduplication-related issues left at this point, yeah?
+
+## bugfixes
+
+* #65 moving deduplicated copies of files (symlinks) from one location to another could make them disappear (break the symlinks)
+
+  * don't worry, we are **not** talking about data loss! but see the [release notes for v1.9.26](https://github.com/9001/copyparty/releases/tag/v1.9.26) which explain how to deal with this issue (how to find, diagnose, and repair broken symlinks)
+
+----
+
+## regarding fedora packages
+
+[copr-pypi](https://copr.fedorainfracloud.org/coprs/g/copr/PyPI/) (fedora's build service) is not building at the moment; ***if you installed copyparty from copr-pypi,*** you can upgrade to this release by running one of the following:

+
+## new features
+* *tumbleweed*
+
+## bugfixes
+
+* deleting files from the server could make some duplicates of that file unavailable (by breaking nested symlinks)
+
+  * don't worry, we are **not** talking about data loss! but such broken links would disappear from the directory listing and would need to be remedied by replacing the broken links manually, either by using a file explorer or commandline
+
+  * **only** affected linux/macos, did **not** affect servers with `--hardlink` or `--never-symlink` or `--no-dedup`, and **mainly** affected servers with lots of duplicate files (with some dupes in the same folder and some elsewhere)
+
+  * if you want to check for such broken symlinks, the following unix command will find all of them: `find -L -type l`
+
+  * to repair a broken link, first remove it and then replace it: `rm thelink.opus; ln -s /mnt/music/realfile.opus thelink.opus`
+
+  * if you are left with a mystery file and want to know where its duplicates are, you can grep for the filename in the logs and you'll find something like the following line, where the `wark` is the file identifier; grep for that to find all the other copies of that file -- `purl` is the folder/URL which that copy of the file was uploaded to:

+* button `full` in the gridview decides if thumbnails should be center-cropped or not
+  * `--no-crop` and the `nocrop` volflag now sets the default value of this instead of forcing the setting
+  * thumbnail cleanup is now more granular, cleaning full-jpg separately from cropped-webp for example
+* set default sort order with `--sort` or volflag `sort`
+  * one or more comma-separated values; `tags/Cirle,tags/.tn,tags/Artist,tags/Title,href`
+    * see the column header tooltips in the browser to know what names (`id`) to use
+  * prefix a column name with `-` for descending sort
+  * specifying a sort order in the client will override all server-defined ones
+* when visiting a read-only folder, the upload-or-filesearch toggle will remember its previous state and restore it when leaving the folder
+  * much more intuitive, if anything about this UI can be called that...

+  * the serverlog will now explain how to trust the reverse-proxy to provide client IPs, but basically,

+  * `--xff-src` is an allowlist of IP-addresses to trust that header from
+* a62f744a187bc9f821b540e8bb4e0b9a67bd01c8 if copyparty was started while an external HDD was not connected, and that volume's index was stored elsewhere, then the index would get wiped (since all the files are gone)

+* some url parameters were double-decoded, causing the unpost filtering and file renaming to fail if the values contained `%`
+* clients could cause the server to return an invalid cache-control header, but newlines and control-characters got rejected correctly
+* minor cosmetics / qol fixes:
+  * reduced flickering on page load in chrome
+  * fixed some console spam in search results
+  * markdown documents now have the same line-height in directory listings and the editor

+# 2023-0826-2116  `v1.9.2`  bigger hammer
+
+## new features
+* more ways to automatically ban users! three new sensors, all default-enabled, giving a 1 day ban after 9 hits in 2 minutes:
+  * `--ban-403`: trying to access volumes that dont exist or require authentication
+  * `--ban-422`: invalid POST messages (from brutefocing POST parameters and such)
+  * `--ban-url`: URLs which 404 and also match `--sus-urls` (scanners/crawlers)
+  * if you want to run a vulnerability scan on copyparty, please just [download the server](https://github.com/9001/copyparty/releases/latest/download/copyparty-sfx.py) and do it locally! takes less than 30 seconds to set up, you get lower latency, and you won't be filling up the logfiles on the demo server with junk, thank you 🙏
+* more ban-related stuff,
+  * new global option `--nonsus-urls` specifies regex of URLs which are OK to 404 and shouldn't ban people
+  * `--turbo` now accepts the value `-1` which makes it impossible for clients to enable it, making `--ban-404` safe to use
+* range-selecting files in the list-view by shift-pgup/pgdn
+* volumes which are currently unavailable (dead nfs share, external HDD which is off, ...) are marked with a ❌ in the directory tree sidebar
+* the toggle-button to see dotfiles is now persisted as a cookie so it also applies on the initial page load
+* more effort is made to prevent `<script>`s inside markdown documents from running in the markdown editor and the fullpage viewer
+  * anyone who wanted to use markdown files for malicious stuff can still just upload an html file instead, so this doesn't make anything more secure, just less confusing
+  * the safest approach is still the `nohtml` volflag which disables markdown rendering outside sandboxes entirely, or only giving out write-access to trustworthy people
+  * enabling markdown plugins with `-emp` now has the side-effect of cancelling this band-aid too
+
+## bugfixes
+* textfile navigation hotkeys broke in the previous version
+
+## other changes
+* example [nginx config](https://github.com/9001/copyparty/blob/hovudstraum/contrib/nginx/copyparty.conf) was not compatible with cloudflare (suggest `$http_cf_connecting_ip` instead of `$proxy_add_x_forwarded_for`)
+* `copyparty.exe` is now built with python 3.11.5 which fixes [CVE-2023-40217](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-40217)
+  * `copyparty32.exe` is not, because python understandably ended win7 support 
+* [similar software](https://github.com/9001/copyparty/blob/hovudstraum/docs/versus.md):
+  * copyparty appears to be 30x faster than nextcloud and seafile at receiving uploads of many small files
+  * seafile has a size limit when zip-downloading folders

+# 2023-0820-2338  `v1.9.1`  prometheable
+
+## new features
+* #49 prometheus / grafana / openmetrics integration ([see readme](https://github.com/9001/copyparty#prometheus))
+  * read metrics from http://127.0.0.1:3923/.cpr/metrics after enabling with `--stats`
+* download a folder with all music transcoded to opus by adding `?tar=opus` or `?zip&opus` to the URL
+  * can also be used to download thumbnails instead of full images; `?tar=w` for webp, `?tar=j` for jpg
+    * so i guess the long-time requested feature of pre-generating thumbnails kind of happened after all, if you schedule a `curl http://127.0.0.1:3923/?tar=w >/dev/null` after server startup
+* u2c (commandline uploader): argument `-x` to exclude files by regex (compares absolute filesystem paths)
+* `--zm-spam 30` can be used to improve zeroconf / mDNS reliability on crazy networks
+  * only necessary if there are clients with multiple IPs and some of the IPs are outside the subnets that copyparty are in -- not spec-compliant, not really recommended, but shouldn't cause any issues either
+  * and `--mc-hop` wasn't actually implemented until now
+* dragging an image from another browser window onto the upload button is now possible
+  * only works on chrome, and only on windows or linux (not macos)
+* server hostname is prefixed in all window titles
+  * can be adjusted with `--bname` (the file explorer) and `--doctitle` (all other documents)
+  * can be disabled with `--nth` (just window title) or `--nih` (title + header)
+
+## bugfixes
+* docker: the autogenerated seeds for filekeys and account passwords now get persisted to the config volume (thx noktuas)
+* uploading files with fancy filenames could fail if the copyparty server is running on android
+* improve workarounds for some apple/iphone/ios jank (thx noktuas and spiky)
+  * some ui elements had their font-size selected by fair dice roll
+  * the volume control does nothing because [apple disabled it](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), so add a warning
+  * the image gallery cannot be fullscreened [as apple intended](https://developer.mozilla.org/en-US/docs/Web/API/Element/requestFullscreen#browser_compatibility) so add a warning
+
+## other changes
+* file table columns are now limited to browser window width
+* readme: mention that nginx-QUIC is currently very slow (thx noktuas)
+* #50 add a safeguard to the wget plugin in case wget at some point adds support for `file://` or similar

+
+## new features
+* #47 file selection by shift-clicking
+  * in list-view: click a table row to select it, then shift-click another to select all files in-between
+  * in grid-view: either enable the `multiselect` button (mainly for phones/tablets), or the new `sel` button in the `[⚙️] settings` tab (better for mouse+keyboard), then shift-click two files
+* volflag `fat32` avoids a bug in android's sdcardfs causing excessive reindexing on startup if any files were modified on the sdcard since last reboot
+
+## bugfixes
+* minor corrections to the new features from #45
+  * uploader IPs are now visible for `a`dmin accounts in `d2t` volumes as well
+
+## other changes
+* the admin-panel is only accessible for accounts which have the `a` (admin) permission-level in one or more volumes; so instead of giving your user `rwmd` access, you'll want `rwmda` instead:
+  ```bash
+  python3 copyparty-sfx.py -a joe:hunter2 -v /mnt/nas/pub:pub:rwmda,joe
+  ```
+  or in a settings file,
+  ```yaml
+  [/pub]
+    /mnt/nas/pub
+    accs:
+      rwmda: joe
+  ```
+  * until now, `rw` was enough, however most readwrite users don't need access to those features
+  * grabbing a stacktrace with `?stack` is permitted for both `rw` and `a`

+# 2023-0714-1558  `v1.8.2`  URGENT: fix path traversal vulnerability
+
+* read-only demo server at https://a.ocv.me/pub/demo/
+* [docker image](https://github.com/9001/copyparty/tree/hovudstraum/scripts/docker) ╱ [similar software](https://github.com/9001/copyparty/blob/hovudstraum/docs/versus.md) ╱ [client testbed](https://cd.ocv.me/b/)
+
+Starting with the bad and important news; this release fixes https://github.com/9001/copyparty/security/advisories/GHSA-pxfv-7rr3-2qjg / [CVE-2023-37474](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-37474) -- so please upgrade!
+
+Every version until now had a [path traversal vulnerability](https://owasp.org/www-community/attacks/Path_Traversal) which allowed read-access to any file on the server's filesystem. To summarize,
+* Every file that the copyparty process had the OS-level permissions to read, could be retrieved over HTTP without password authentication
+* However, an attacker would need to know the full (or copyparty-module-relative) path to the file; it was luckily impossible to list directory contents to discover files on the server
+* You may have been running copyparty with some mitigations against this:
+  * [prisonparty](https://github.com/9001/copyparty/tree/hovudstraum/bin#prisonpartysh) limited the scope of access to files which were intentionally given to copyparty for sharing; meaning all volumes, as well as the following read-only filesystem locations: `/bin`, `/lib`, `/lib32`, `/lib64`, `/sbin`, `/usr`, `/etc/alternatives`
+  * the [nix package](https://github.com/9001/copyparty#nix-package) has a similar mitigation implemented using systemd concepts
+  * [docker containers](https://github.com/9001/copyparty/tree/hovudstraum/scripts/docker) would only expose the files which were intentionally mounted into the container, so even better
+* More conventional setups, such as just running the sfx (python or exe editions), would unfortunately expose all files readable by the current user
+* The following configurations would have made the impact much worse:
+  * running copyparty as root
+
+So, three years, and finally a CVE -- which has been there since day one... Not great huh. There is a list of all the copyparty alternatives that I know of in the `similar software` link above.
+
+Thanks for flying copyparty! And especially if you decide to continue doing so :-)
+
+## new features
+* #43 volflags to specify thumbnailer behavior per-volume;
+  * `--th-no-crop` / volflag `nocrop` to specify whether autocrop should be disabled
+  * `--th-size` / volflag `thsize` to set a custom thumbnail resolution
+  * `--th-convt` / volflag `convt` to specify conversion timeout
+* #45 resulted in a handful of opportunities to tighten security in intentionally-dangerous setups (public folders with anonymous uploads enabled):
+  * a new permission, `a` (in addition to the existing `rwmdgG`), to show the uploader-IP and upload-time for each file in the file listing
+    * accidentally incompatible with the `d2t` volflag (will be fixed in the next ver)
+  * volflag `nohtml` is a good defense against (un)intentional XSS; it returns HTML-files and markdown-files as plaintext instead of rendering them, meaning any malicious `<script>` won't run -- bad idea for regular use since it breaks fundamental functionality, but good when you really need it
+    * the README-previews below the file-listing still renders as usual, as this is fine thanks to the sandbox
+  * a new eventhook `--xban` to run a plugin when copyparty decides to ban someone (for password bruteforcing or excessive 404's), for example to blackhole the IP using fail2ban or similar
+
+## bugfixes
+* **fixes a path traversal vulnerability,** https://github.com/9001/copyparty/security/advisories/GHSA-pxfv-7rr3-2qjg / [CVE-2023-37474](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-37474)
+  * HUGE thanks to @TheHackyDog for reporting this !!
+  * if you use a reverse proxy, you can check if you have been exploited like so:
+    * nginx: grep your logs for URLs containing both `.cpr/` and `%2[^0]`, for example using the following command:
+      ```bash
+      (gzip -dc access.log.*.gz; cat access.log) | sed -r 's/" [0-9]+ .*//' | grep -E 'cpr/.*%2[^0]' | grep -vF data:image/svg
+      ```
+* 77f1e5144455eb946db7368792ea11c934f0f6da fixes an extremely unlikely race-condition (see the commit for details)
+* 8f59afb1593a75b8ce8c91ceee304097a07aea6e fixes another race-condition which is a bit worse:
+  * the unpost feature could collide with other database activity, with the worst-case outcome being aborted batch operations, for example a directory move or a batch-rename which stops halfways

+
+News: if you use rclone as a copyparty webdav client, upgrading to [rclone v1.63](https://github.com/rclone/rclone/releases/tag/v1.63.0) (just released) will give you [a huge speed boost](https://github.com/rclone/rclone/pull/6897) for small files
+
+## new features
+* #39 hashed passwords
+  * instead of keeping plaintext account passwords in config files, you can now store hashed ones instead
+  * `--ah-alg` specifies algorithm; best to worst: `argon2`, `scrypt`, `sha2`, or the default `none`
+  * the default settings of each algorithm takes `0.4 sec` to hash a password, and argon2 eats `256 MiB` RAM
+    * can be adjusted with optional comma-separated args after the algorithm name; see `--help-pwhash`
+  * `--ah-salt` is the [static salt](https://github.com/9001/copyparty/blob/hovudstraum/docs/devnotes.md#hashed-passwords) for all passwords, and is autogenerated-and-persisted if not specified
+  * `--ah-cli` switches copyparty into a shell where you can hash passwords interactively
+    * but copyparty will also autoconvert any unhashed passwords on startup and give you the values to insert into the config anyways
+* #40 volume size limit
+  * volflag `vmaxb` specifies max size of a volume
+  * volflag `vmaxn` specifies max number of files in a volume
+  * example: `-v [...]:c,vmaxb=900g:c,vmaxn=20k` blocks uploads if the volume reaches 900 GiB or a total of 20480 files
+  * good alternative to `--df` since it works per-volume

+* the default `--fk-salt` is now much stronger
+  * all existing installations will keep the previously selected seed -- you can choose to upgrade by deleting `~/.config/copyparty/cert.pem` but this will change all filekeys / per-file passwords
+* the `NO_COLOR` environment-variable is now supported, removing colors from stdout
+  * see https://no-color.org/ and more importantly https://youtu.be/biW5UVGkPMA?t=150

+* #33 disable colors when stdout is redirected to a pipe/file -- by @clach04 
+* #32 simplify building sfx from source
+* upgraded [copyparty.exe](https://github.com/9001/copyparty/releases/latest/download/copyparty.exe) to [python 3.11.4](https://pythoninsider.blogspot.com/2023/06/python-3114-31012-3917-3817-3717-and.html)

 I didn't know about [tus](https://tus.io/)  when I made this, but:
 * up2k has the advantage that it supports parallel uploading of non-contiguous chunks straight into the final file -- [tus does a merge at the end](https://tus.io/protocols/resumable-upload.html#concatenation) which is slow and taxing on the server HDD / filesystem (unless i'm misunderstanding)
 * up2k has the slight disadvantage of requiring the client to hash the entire file before an upload can begin, but this has the benefit of immediately skipping duplicate files
   * and the hashing happens in a separate thread anyways so it's usually not a bottleneck

+regarding the curious decisions
+
+there is a static salt for all passwords;
+* because most copyparty APIs allow users to authenticate using only their password, making the username unknown, so impossible to do per-account salts
+* the drawback of this is that an attacker can bruteforce all accounts in parallel, however most copyparty instances only have a handful of accounts in the first place, and it can be compensated by increasing the hashing cost anyways
