+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:
+
+```bash
+dnf install https://ocv.me/copyparty/fedora/37/python3-copyparty.fc37.noarch.rpm
+dnf install https://ocv.me/copyparty/fedora/38/python3-copyparty.fc38.noarch.rpm

+# 2023-1208-0136  `v1.9.26`  dont break symlinks
+
+## 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:
+    ```json
+    {"name": "04. GHOST.opus", "purl": "/mu/vt/suisei/still-still-stellar/", "size": 4520986, "lmod": 1697091772, "sprs": true, "hash": [], "wark": "SJMASMtWOa0UZnc002nn5unO5iCBMa-krt2CDcq8eJe9"}
+    ```
+
+* the server would throw an error if you tried to delete a broken symlink
+* prevent warnings about duplicate file entries in the database by preventing that from happening in the first place
+* `u2c.py` (commandline uploader) would fail to delete files from the server if there's more than ~10'000 files to be deleted
+  * and forgot to bump the version number... `1.11 (2nd season)`
+
+## other changes
+* `--help` was slightly improved
+* docker images are now based on alpine v3.19
+* `copyparty.exe` is now based on python v3.11.7

+  * only authentication so far; no authorization yet, and users must exist in the copyparty config with bogus passwords
+* new option `--ipa` rejects connections from clients outside of a given allowlist of IP prefixes
+* environment variables can be used almost everywhere that takes a filesystem path; should make it way more comfy to write configs for docker / systemd
+* #59 added a basic [docker-compose yaml](https://github.com/9001/copyparty/blob/hovudstraum/docs/examples/docker/basic-docker-compose) and an example config
+  * probably much room for improvement on everything docker still
+
+## bugfixes
+* the nftables-based port-forwarding in the [systemd example](https://github.com/9001/copyparty/tree/hovudstraum/contrib/systemd) was buggy; replaced with CAP_NET_BIND_SERVICE
+* palemoon-specific js crash if a text selection was dragged
+* text selection in messageboxes was jank
+
+## other changes
+* improved [systemd example](https://github.com/9001/copyparty/tree/hovudstraum/contrib/systemd) with hardening and a better example config
+* logfiles are flushed for every line written; can be disabled with `--no-logflush` for ~3% more performance best-case
+* iphones probably won't broadcast cover-art to car stereos over bluetooth anymore since the thingamajig in iOS that's in charge of that doesn't have cookie-access, and strapping in the auth is too funky so let's stop doing that b7723ac245b8b3e38d6410891ef1aa92d4772114
+  * can be remedied by enabling filekeys and granting unauthenticated people access that way, but that's too much effort for anyone to bother with I'm sure

+* browser: the mkdir feature now accepts `foo/bar/qux` and `../foo` and `/bar`
+* add 14 more prometheus metrics; see [readme](https://github.com/9001/copyparty#prometheus) for details
+  * connections, requests, malicious requests, volume state, file hashing/analyzation queues
+* catch some more malicious requests in the autoban filters
+  * some malicious requests are now answered with HTTP 422, so that they count against `--ban-422`
+
+## bugfixes
+* windows: fix symlink-based upload deduplication
+  * MS decided to make symlinks relative to working-directory rather than destination-path...
+* `--stats` would produce invalid metrics if a volume was offline
+* minor improvements to password hashing ux:
+  * properly warn if `--ah-cli` or `--ah-gen` is used without `--ah-alg`
+  * support `^D` during `--ah-cli`
+* browser-ux / cosmetics:
+  * fix toast/tooltip colors on splashpage
+  * easier to do partial text selection inside links (search results, breadcrumbs, uploads)
+  * more rclone-related hints on the connect-page
+
+## other changes
+* malformed http headers from clients are no longer included in the client error-message
+  * just in case there are deployments with a reverse-proxy inserting interesting stuff on the way in
+  * the serverlog still contains all the necessary info to debug your own clients
+* updated [example nginx config](https://github.com/9001/copyparty/blob/hovudstraum/contrib/nginx/copyparty.conf) to recover faster from brief server outages
+  * the default value of `fail_timeout` (10sec) makes nginx cache the outage for longer than necessary

+this example is also available as a podman-compatible [docker-compose yaml](https://github.com/9001/copyparty/blob/hovudstraum/docs/examples/docker/basic-docker-compose); example usage: `docker-compose up` (you may need to `systemctl enable --now podman.socket` or similar)

 ## configuration

+> this section basically explains how the [docker-compose yaml](https://github.com/9001/copyparty/blob/hovudstraum/docs/examples/docker/basic-docker-compose) works, so you may look there instead
+
 the container has the same default config as the sfx and the pypi module, meaning it will listen on port 3923 and share the "current folder" (`/w` inside the container) as read-write for anyone

 the recommended way to configure copyparty inside a container is to mount a folder which has one or more [config files](https://github.com/9001/copyparty/blob/hovudstraum/docs/example.conf) inside; `-v /your/config/folder:/cfg`

+* `self.` are grabbed from copyparty's internal state; anything in `httpcli.py` is fair game
+* `cfg.` are the global server settings
+* `vf.` are the volflags of the current volume
+* `hdr.` are grabbed from the client headers; any header is supported, just add it (in lowercase) to the allowlist
+* `srv.` are processed inside the `_expand` function in httpcli
+
+for example (bad example), `hdr_cf_ipcountry` maps to the header `CF-IPCountry` (which is generated by cloudflare before the request is passed on to your server / copyparty)

ed	0c50ea1757	list dotfiles only for specific volumes or users (#66 ): * permission `.` grants dotfile visibility if user has `r` too * `-ed` will grant dotfiles to all `r` accounts (same as before) * volflag `dots` likewise also drops compatibility for pre-0.12.0 `-v` syntax (`-v .::red` will no longer translate to `-v .::r,ed`)	2023-12-16 15:38:48 +00:00

ed	9672b8c9b3	ensure nested symlinks are not broken during deletes; when moving/deleting a file, all symlinked dupes are verified to ensure this action does not break any symlinks, however it did this by checking the realpath of each link. This was not good enough, since the deleted file may be a part of a series of nested symlinks this situation occurs because the deduper tries to keep relative symlinks as close as possible, only traversing into parent/sibling folders as required, which can lead to several levels of nested links	2023-12-08 01:11:03 +00:00
