# 2023-0831-2211  `v1.9.3`  iOS and http fixes

## new features
* iPhones and iPads are now able to...
  * 9986136dfb2364edb35aa9fbb87410641c6d6af3 play entire albums while the screen is off without the music randomly stopping
    * apple keeps breaking AudioContext in new and interesting ways; time to give up (no more equalizer)
  * 1c0d978979a703edeb792e552b18d3b7695b2d90 perform search queries and execude js code
    * by translating [smart-quotes](https://stackoverflow.com/questions/48678359/ios-11-safari-html-disable-smart-punctuation) into regular `'` and `"` characters
* python 3.12 support
  * technically a bugfix since it was added [a year ago](https://github.com/9001/copyparty/commit/32e22dfe84d5e0b13914b4d0e15c1b8c9725a76d) way before the first py3.12 alpha was released but turns out i botched it, oh well
* filter error messages so they never include the filesystem path where copyparty's python files reside
* print more context in server logs if someone hits an unexpected permission-denied

# bugfixes
found some iffy stuff combing over the code but, as far as I can tell, luckily none of these were dangerous:
* URL normalization was a bit funky, but it appears everything access-control-related was unaffected
* 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
* show a suggestion on startup to enable the database

# 2023-0725-1550  `v1.8.8`  just boring bugfixes

final release until late august unless something bad happens and i end up building this thing on a shinkansen

## recent security / vulnerability fixes
* there is a [discord server](https://discord.gg/25J8CdTT6G) with an `@everyone` in case of future important updates
* [v1.8.7](https://github.com/9001/copyparty/releases/tag/v1.8.7) (2023-07-23) - [CVE-2023-38501](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-38501) - reflected XSS
* [v1.8.2](https://github.com/9001/copyparty/releases/tag/v1.8.2) (2023-07-14) - [CVE-2023-37474](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-37474) - path traversal (first CVE)
  * all serverlogs reviewed so far (5 public servers) showed no signs of exploitation

## bugfixes
* range-select with shiftclick:
  * don't crash when entering another folder and shift-clicking some more
  * remember selection origin when lazy-loading more stuff into the viewport
* markdown editor:
  * fix confusing warnings when the browser cache decides it *really* wants to cache
  * and when a document starts with a newline
* remember intended actions such as `?edit` on login prompts
* Windows: TLS-cert generation (triggered by network changes) could occasionally fail

# 2023-0723-1543  `v1.8.7`  XSS for days

at the lack of better ideas, there is now a [discord server](https://discord.gg/25J8CdTT6G) with an `@everyone` for all future important updates such as this one

## bugfixes
* reflected XSS through `/?k304` and `/?setck`
  * if someone tricked you into clicking a URL containing a chain of `%0d` and `%0a` they could potentially have moved/deleted existing files on the server, or uploaded new files, using your account
  * if you use a reverse proxy, you can check if you have been exploited like so:
    * nginx: grep your logs for URLs containing `%0d%0a%0d%0a`, for example using the following command:
      ```bash
      (gzip -dc access.log*.gz; cat access.log) | sed -r 's/" [0-9]+ .*//' | grep -iE '%0[da]%0[da]%0[da]%0[da]'
      ```
  * if you find any traces of exploitation (or just want to be on the safe side) it's recommended to change the passwords of your copyparty accounts
  * huge thanks *again* to @TheHackyDog !
* the original fix for CVE-2023-37474 broke the download links for u2c.py and partyfuse.py
* fix mediaplayer spinlock if the server only has a single audio file

  * if someone tricked you into clicking `http://127.0.0.1:3923/?hc=<script>alert(1)</script>` they could potentially have moved/deleted existing files on the server, or uploaded new files, using your account
  * if you use a reverse proxy, you can check if you have been exploited like so:
    * nginx: grep your logs for URLs containing `?hc=` with `<` somewhere in its value, for example using the following command:

# 2023-0718-0746  `v1.8.4`  range-select v2

**IMPORTANT:** `v1.8.2` (previous release) fixed [CVE-2023-37474](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-37474) ; please see the [1.8.2 release notes](https://github.com/9001/copyparty/releases/tag/v1.8.2) (all serverlogs reviewed so far showed no signs of exploitation)

* 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/)

## 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

# 2023-0626-0005  `v1.8.0`  argon

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

## bugfixes
* autogenerated TLS certs didn't include the mDNS name

## other changes
* improved cloudflare challenge detection
* markdown edits will now trigger upload hooks

# 2023-0611-0814  `v1.7.6`  NO_COLOR

## new features
* #31 `--grid` shows thumbnails instead of file-list by default
* #28 `--unlist` regex-exclude files from browser listings
  * for example `--unlist '\.(js|css)$'` hides all `.js` and `.css` files
  * **purely cosmetic!** the files are still fully accessible, and still appear in API calls
* auto-generate TLS certificates on startup / network-change
  * mostly good for LAN, requires [cfssl](https://github.com/cloudflare/cfssl/releases/latest), can be disabled with `--no-crt`
  * creates a self-signed CA and certs with SANs of all detected server IPs
    * so it's still recommended to use a reverse-proxy / letsencrypt for WAN servers
* 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
  * `--ansi` and `--no-ansi` can also be used to force-enable/disable colored output
* #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)

## bugfixes

# 2023-0507-1834  `v1.7.1`  CräzY;PWDs

## new features
* webdav:
  * support write-only folders
  * option `--dav-auth` / volflag `davauth` forces clients to always auth
    * helps clients such as `davfs2` see all folders if the root is anon-readable but some subfolders are not
    * alternatively you could configure your client to always send the password in the `PW` header
* include usernames in http request logs
* audio player:
  * consumes less power on phones when the screen is off
  * smoother playback cursor on short songs

## bugfixes
* the characters `;` and `%` can now be used in passwords
  * but non-ascii characters (such as the ä in the release title) can, in fact, not
* verify that all accounts have unique passwords on startup (#25)

## other changes
* ftpd: log incorrect passwords only, not correct ones
* `up2k.py` (the upload, folder-sync, and file-search client) has been renamed to [u2c.py](https://github.com/9001/copyparty/tree/hovudstraum/bin#u2cpy)
  * `u2c` as in `up2k client`, or `up2k CLI`, or `upload-to-copyparty` -- good name
  * now the only things named "up2k" are the web-ui and the server backend which is way less confusing
* upgrade packaging from [setup.py](https://github.com/9001/copyparty/blob/hovudstraum/setup.py) to [pyproject.toml](https://github.com/9001/copyparty/blob/hovudstraum/pyproject.toml)
  * no practical consequences aside from a warm fuzzy feeling of being in the future
* the docker images ~~will be~~ got rebuilt 2023-05-11 ~~in a few days (when [alpine](https://alpinelinux.org/) 3.18 is released)~~ enabling [the chiptune player](https://a.ocv.me/pub/demo/music/chiptunes/#af-f6fb2e5f)

# 2023-0429-2114  `v1.7.0`  unlinked

don't get excited! nothing new and revolutionary, but `xvol` and `xdev` changed behavior so there's an above-average chance of fresh bugs

## new features
* (#24): `xvol` and `xdev`, previously just hints to the filesystem indexer, now actively block access as well:
  * `xvol` stops users following symlinks leaving the volumes they have access to
    * so if you symlink `/home/ed/music` into `/srv/www/music` it'll get blocked
    * ...unless both folders are accessible through volumes, and the user has read-access to both
  * `xdev` stops users crossing the filesystem boundary of the volumes they have access to
    * so if you symlink another HDD into a volume it'll get blocked, but you can still symlink from other places on the same FS
  * enabling these will add a slight performance hit; the unlikely worst-case is `14%` slower directory listings, `35%` slower download-as-tar
* file selection summary (num files, size, audio duration) in the bottom right
* [u2cli](https://github.com/9001/copyparty/blob/hovudstraum/bin/up2k.py): more aggressive resolving with `--rh`
* [add a warning](https://github.com/9001/copyparty#fix-unreliable-playback-on-android) that the default powersave settings in android may stop playing music during album changes
  * also appears [in the media player](https://user-images.githubusercontent.com/241032/235327191-7aaefff9-5d41-4e42-b71f-042a8247f29d.png) if the issue is detected at runtime (playback halts for 30sec while screen is off)

## bugfixes
* (#23): stop autodeleting empty folders when moving or deleting files
  * but files which expire / [self-destruct](https://github.com/9001/copyparty#self-destruct) still clean up parent directories like before
* ftp-server: some clients could fail to `mkdir` at first attempt (and also complain during rmdir)

## other changes
* new version of [cpp-winpe64.exe](https://github.com/9001/copyparty/releases/download/v1.7.0/copyparty-winpe64.exe) since the ftp-server fix might be relevant

# 2023-0426-2300  `v1.6.15`  unexpected boost

## new features
* 30% faster folder listings due to [the very last thing](https://github.com/9001/copyparty/commit/55c74ad164633a0a64dceb51f7f534da0422cbb5) i'd ever expect to be a bottleneck, [thx perf](https://docs.python.org/3.12/howto/perf_profiling.html)
* option to see the lastmod timestamps of symlinks instead of the target files
  * makes the turbo mode of [u2cli, the commandline uploader and folder-sync tool](https://github.com/9001/copyparty/blob/hovudstraum/bin/up2k.py) more turbo since copyparty dedupes uploads by symlinking to an existing copy and the symlink is stamped with the deduped file's lastmod
  * **webdav:** enabled by default (because rclone will want this), can be disabled with arg `--dav-rt` or volflag `davrt`
  * **http:** disabled by default, can be enabled per-request with urlparam `lt`
* [u2cli](https://github.com/9001/copyparty/blob/hovudstraum/bin/up2k.py): option `--rh` to resolve server hostname only once at start of upload
  * fantastic for buggy networks, but it'll break TLS

## bugfixes
* new arg `--s-tbody` specifies the network timeout before a dead connection gets dropped (default 3min)
  * before there was no timeout at all, which could hang uploads or possibly consume all server resources
  * ...but this is only relevant if your copyparty is directly exposed to the internet with no reverse proxy
    * with nginx/caddy/etc you can disable the timeout with `--s-tbody 0` for a 3% performance boost (*wow!*)
* iPhone audio transcoder could turn bad and stop transcoding
* ~~maybe android phones no longer pause playback at the end of an album~~
  * nope, that was due to [android's powersaver](https://github.com/9001/copyparty#fix-unreliable-playback-on-android), oh well
  * ***bonus unintended feature:*** navigate into other folders while a song is plaing
* [installing from the source tarball](https://github.com/9001/copyparty/blob/hovudstraum/docs/devnotes.md#build-from-release-tarball) should be ok now
  * good base for making distro packages probably

## other changes
* since the network timeout fix is relevant for the single usecase that [cpp-winpe64.exe](https://github.com/9001/copyparty/releases/download/v1.6.15/copyparty-winpe64.exe) covers, there is now a new version of that

# 2023-0424-0609  `v1.6.14`  unsettable flags

## new features
* unset a volflag (override a global option) by negating it (setting volflag `-flagname`)
* new argument `--cert` to specify TLS certificate location
  * defaults to `~/.config/copyparty/cert.pem` like before

## bugfixes
* in zip/tar downloads, always use the parent-folder name as the archive root
* more reliable ftp authentication when providing password as username
* connect-page: fix rclone ftps example

## other changes
* stop suggesting `--http-only` and `--https-only` for performance since the difference is negligible
* mention how some antivirus (avast, avg, mcafee) thinks that pillow's webp encoder is a virus, affecting `copyparty.exe`

# 2023-0420-2141  `v1.6.12`  as seen on nixos

## new features
* @chinponya [made](https://github.com/9001/copyparty/pull/22) a copyparty [Nix package](https://github.com/9001/copyparty#nix-package) and a [NixOS module](https://github.com/9001/copyparty#nixos-module)! nice 🎉
  * with [systemd-based hardening](https://github.com/9001/copyparty/blob/hovudstraum/contrib/nixos/modules/copyparty.nix#L230-L270) instead of [prisonparty](https://github.com/9001/copyparty/blob/hovudstraum/bin/prisonparty.sh)
  * complements the [arch package](https://github.com/9001/copyparty/tree/hovudstraum/contrib/package/arch) very well w

## bugfixes
* fix an sqlite fd leak
  * with enough simultaneous traffic, copyparty could run out of file descriptors since it relied on the gc to close sqlite cursors
  * now there's a pool of cursors shared between the tcp connections instead, limited to the number of CPU cores
  * performance mostly unaffected (or slightly improved) compared to before, except for a 20% reduction only during max server load caused by directory-listings or searches
  * ~~somehow explicitly closing the cursors didn't always work... maybe this was actually a python bug :\\/~~
    * yes, it does incomplete cleanup if opening a WAL database fails
* multirange requests would fail with an error; now they get a 200 as expected (since they're kinda useless and not worth the overhead)
  * [the only software i've ever seen do that](https://apps.kde.org/discover/) now works as intended
* expand `~/` filesystem paths in all remaining args: `-c`, `-lo`, `--hist`, `--ssl-log`, and the `hist` volflag
* never use IPv6-format IPv4 (`::ffff:127.0.0.1`) in responses
* [u2cli](https://github.com/9001/copyparty/blob/hovudstraum/bin/up2k.py): don't enter delete stage if some of the uploads failed
* audio player in safari on touchbar macbooks
  * songs would play backwards because the touchbar keeps spamming play/pause
  * playback would stop when the preloader kicks in because safari sees the new audio object and freaks out

## other changes
* added [windows quickstart / service example](https://github.com/9001/copyparty/blob/hovudstraum/docs/examples/windows.md)
* updated pyinstaller (it makes smaller exe files now)

## bugfixes
* more sqlite query-planner twiddling
  * deleting files is MUCH faster now, and uploads / bootup might be a bit better too
* webdav optimizations / compliance
  * should make some webdav clients run faster than before
  * in very related news, the webdav-client in [rclone](https://github.com/rclone/rclone/) v1.63 ([currently beta](https://beta.rclone.org/?filter=latest)) will be ***FAST!***
    * does cool stuff such as [bidirectional sync](https://github.com/9001/copyparty#folder-sync) between copyparty and a local folder
* [bpm detector](https://github.com/9001/copyparty/blob/hovudstraum/bin/mtag/audio-bpm.py) is a bit more accurate
* [u2cli](https://github.com/9001/copyparty/blob/hovudstraum/bin/up2k.py) / commandline uploader: better error messages if something goes wrong
* readme rendering could fail in firefox if certain addons were installed (not sure which)
* event-hooks: more accurate usage examples

## other changes
* @chinponya automated the prismjs build step (thx!)
* updated some js deps (markedjs, codemirror)

* support `rclone sync` to [sync folders](https://github.com/9001/copyparty#folder-sync) to/from copyparty
  * let webdav clients set lastmodified times during upload
  * let webdav clients replace files during upload

## bugfixes
* [prisonparty](https://github.com/9001/copyparty/blob/hovudstraum/bin/prisonparty.sh): FFmpeg transcoding was slow because there was no `/dev/urandom`
* iphones would fail to play *some* songs (low-bitrate and/or shorter than ~7 seconds)
  * due to either an iOS bug or an FFmpeg bug in the caf remuxing idk
  * fixed by mixing in white noise into songs if an iPhone asks for them

# 2023-0305-2018  `v1.6.7`  fix no-dedup + add up2k.exe

## new features
* controlpanel-connect: add example for webdav automount

## bugfixes
* fix a race which, in worst case (but unlikely on linux), **could cause data loss**
  * could only happen if `--no-dedup` or volflag `copydupes` was set (**not** default)
  * if two identical files were uploaded at the same time, there was a small chance that one of the files would become empty
  * check if you were affected by doing a search for zero-byte files using either of the following:

* *no https support* (saves space + the python3.7 openssl is getting old)
* built from b39ff92f34e3fca389c78109d20d5454af761f8e so it can do long filepaths and mojibake

  * pls let me know if you actually run copyparty on an IBM mainframe 👍
* new [event hook](https://github.com/9001/copyparty/tree/hovudstraum/bin/hooks) type `xiu` runs just once for all recent uploads
  * example hook [xiu-sha.py](https://github.com/9001/copyparty/blob/hovudstraum/bin/hooks/xiu-sha.py) generates sha512 checksum files
* new arg `--rsp-jtr` simulates connection jitter
* copyparty.exe integrity selftest

## bugfixes
* permit replacing empty files only during a `--blank-wt` grace period
* lifetimes: keep upload-time when a size/mtime change triggers a reindex
* during cleanup after an unlink, never rmdir the entire volume
* rescan button in the controlpanel required volumes to be e2ds
* dupes could get indexed with the wrong mtime

# 2023-0212-1411  `v1.6.5`  windows smb fix + win10.exe

## bugfixes
* **windows-only:** smb locations (network drives) could not be accessed
  * appeared in [v1.6.4](https://github.com/9001/copyparty/releases/tag/v1.6.4) while adding support for long filepaths (260chars+)

## other changes
* removed tentative support for compressed chiptunes (xmgz, xmz, xmj, ...) since FFmpeg usually doesn't

----

# introducing [copyparty640.exe](https://github.com/9001/copyparty/releases/download/v1.6.5/copyparty640.exe)
* built for win10, comes with the latest python and deps (supports win8 with [vc redist 2015](https://www.microsoft.com/en-us/download/details.aspx?id=48145))
* __*much* safer__ than the old win7-compatible `copyparty.exe` and `copyparty64.exe`
  * but only `copyparty-sfx.py` takes advantage of the operating system security patches
* includes pillow for thumbnails and mutagen for media indexing
* around 10% slower (trying to figure out what's up with that)

starting from the next release,
* `copyparty.exe` (win7 x32) will become `copyparty32.exe`
* `copyparty640.exe` (win10) will be the new `copyparty.exe`
* `copyparty64.exe` (win7 x64) will graduate

so the [copyparty64.exe](https://github.com/9001/copyparty/releases/download/v1.6.5/copyparty64.exe) in this release will be the "final" version able to run inside a [64bit Win7-era winPE](https://user-images.githubusercontent.com/241032/205454984-e6b550df-3c49-486d-9267-1614078dd0dd.png) (all regular 32/64-bit win7 editions can just use `copyparty32.exe` instead)

    * `--vc` prints the autoconverted config which you can copy back into the config file to upgrade
  * `--vc` will also [annotate and explain](https://user-images.githubusercontent.com/241032/217356028-eb3e141f-80a6-4bc6-8d04-d8d1d874c3e9.png) the config files
  * new argument `--cgen` to generate config from commandline arguments
    * kinda buggy, especially the `[global]` section, so give it a lookover before saving it
* 🎲 randomize filenames on upload
  * either optionally, using the 🎲 button in the up2k ui
  * or force-enabled; globally with `--rand` or per-volume with volflag `rand`
  * specify filename length with `nrand` (globally or volflag), default 9
* 🔗 export a list of links to your recent uploads
  * `copy links` in the up2k tab (🚀) will copy links to all uploads since last page refresh,
  * `copy` in the unpost tab (🧯) will copy links to all your recent uploads (max 2000 files / 12 hours by default)
  * filekeys are included if that's enabled and you have access to view those (permissions `G` or `r`)
* 🇦 [arch package](https://github.com/9001/copyparty/tree/hovudstraum/contrib/package/arch) -- added in #18, thx @icxes 
  * maybe in aur soon!
* 🐳 [docker containers](https://github.com/9001/copyparty/tree/hovudstraum/scripts/docker) -- 5 editions,
  * [min](https://hub.docker.com/r/copyparty/min) (57 MiB), just copyparty without thumbnails or audio transcoding
  * [im](https://hub.docker.com/r/copyparty/im) (70 MiB), thumbnails of popular image formats + media tags with mutagen
  * [ac (163 MiB)](https://hub.docker.com/r/copyparty/ac) 🥇 adds audio/video thumbnails + audio transcoding + better tags
  * [iv](https://hub.docker.com/r/copyparty/iv) (211 MiB), makes heif/avic/jxl faster to thumbnail
  * [dj](https://hub.docker.com/r/copyparty/dj) (309 MiB), adds optional detection of musical key / bpm
* 🎶 [chiptune player](https://a.ocv.me/pub/demo/music/chiptunes/#af-f6fb2e5f)
  * transcodes mod/xm/s3m/it/mo3/mptm/mt2/okt to opus
  * uses FFmpeg (libopenmpt) so the accuracy is not perfect, but most files play OK enough
  * not **yet** supported in the docker container since Alpine's FFmpeg was built without libopenmpt
* windows: support long filepaths (over 260 chars)
  * uses the `//?/` winapi syntax to also support windows 7
* `--ver` shows the server version on the control panel

## bugfixes
* markdown files didn't scale properly in the document browser
* detect and refuse multiple volume definitions sharing the same filesystem path
* don't return incomplete transcodes if multiple clients try to play the same flac file
* [prisonparty](https://github.com/9001/copyparty/blob/hovudstraum/bin/prisonparty.sh): more reliable chroot cleanup, sigusr1 for config reload
* pypi packaging: compress web resources, include webdav.bat

# 2023-0131-2103  `v1.6.3`  sandbox k

* read-only demo server at https://a.ocv.me/pub/demo/
* and since [1.6.0](https://github.com/9001/copyparty/releases/tag/v1.6.2) only got 2 days of prime time,
  * [1.6 theme song](https://a.ocv.me/pub/demo/music/.bonus/#af-134e597c) (hosted on the demo server)
  * [similar software](https://github.com/9001/copyparty/blob/hovudstraum/docs/versus.md) / feature comparison

## new features
* dotfiles are hidden from search results by default
  * use `--dotsrch` or volflags `dotsrch` / `nodotsrch` to specify otherwise
  * they were already being excluded from tar/zip-files if `-ed` is not set, so this makes more sense -- dotfiles *should* now be undiscoverable unless `-ed` or `--smb` is set, but please use [volumes](https://github.com/9001/copyparty#accounts-and-volumes) for isolation / access-control instead, much safer

## bugfixes
* lots of cosmetic fixes for the new readme/prologue/epilogue sandbox
  * rushed it into the previous release when someone suggested it, bad idea
  * still flickers a bit (especially prologues), and hotkeys are blocked while the sandboxed document has focus
  * can be disabled with `--no-sb-md --no-sb-lg` (not recommended)
* support webdav uploads from davfs2 (fix LOCK response)
* always unlink files before overwriting them, in case they are hardlinks
  * was primarily an issue with `--daw` and webdav clients
* on windows, replace characters in PUT filenames as necessary
* [prisonparty](https://github.com/9001/copyparty/blob/hovudstraum/bin/prisonparty.sh): support opus transcoding on debian
  * `rm -rf .hist/ac` to clear the transcode cache if the old version broke some songs

## other changes
* add `rel="nofollow"` to zip download links, basic-browser link

# 2023-0129-1842  `v1.6.2`  cors k

[Ellie Goulding - Stay Awake (kors k Hardcore Bootleg).mp3](https://a.ocv.me/pub/demo/music/.bonus/#af-134e597c)
* 👆 the read-only demo server at https://a.ocv.me/pub/demo/

## breaking changes
but nothing is affected (that i know of):
* all requests must pass [cors validation](https://github.com/9001/copyparty#cors)
  * but they almost definitely did already
  * sharex and others are OK since they don't supply an `Origin` header
* [API calls](https://github.com/9001/copyparty/blob/hovudstraum/docs/devnotes.md#http-api) `?delete` and `?move` are now POST instead of GET
  * not aware of any clients using these

## known issues
* the document sandbox is a bit laggy and sometimes eats hotkeys
  * disable it with `--no-sb-md --no-sb-lg` if you trust everyone who has write and/or move access

## new features
* [event hooks](https://github.com/9001/copyparty/tree/hovudstraum/bin/hooks) -- run programs on new [uploads](https://user-images.githubusercontent.com/241032/215304439-1c1cb3c8-ec6f-4c17-9f27-81f969b1811a.png), renames, deletes
* [configurable cors](https://github.com/9001/copyparty#cors) (cross-origin resource sharing) behavior; defaults are mostly same as before
  * `--allow-csrf` disables all csrf protections and makes it intentionally trivial to send authenticated requests from other domains
* sandboxed readme.md / prologues / epilogues
  * documents can still run scripts like before, but can no longer tamper with the web-ui / read the login session, so the old advice of `--no-readme` and `--no-logues` is mostly deprecated
  * unfortunately disables hotkeys while the text has focus + blocks dragdropping files onto that area, oh well
* password can be provided through http header `PW:` (instead of cookie `cppwd` or or url-param `?pw`)
* detect network changes (new NICs, IPs) and reconfigure / reannoucne zeroconf
  * fixes mdns when running as a systemd service and copyparty is started before networking is up
* add `--freebind` to start listening on IPs before the NIC is up yet (linux-only)
* per-volume deduplication-control with volflags `hardlink`, `neversymlink`, `copydupes`
* detect curl and return a [colorful, sortable plaintext](https://user-images.githubusercontent.com/241032/215322619-ea5fd606-3654-40ad-94ee-2bc058647bb2.png) directory listing instead
* add optional [powered-by-copyparty](https://user-images.githubusercontent.com/241032/215322626-11d1f02b-25f4-45df-a3d9-f8c51354a8eb.png) footnode on the controlpanel
  * can be disabled with `-nb` or redirected with `--pb-url`

## bugfixes
* change some API calls (`?delete`, `?move`) from `GET` to `POST`
  * don't panic! this was safe against authenticated csrf thanks to [SameSite=Lax](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie/SameSite#lax)
  * `--getmod` restores the GETs if you need the convenience and accept the risks
* [u2cli](https://github.com/9001/copyparty/blob/hovudstraum/bin/up2k.py) (command-line uploader):
  * recover from network hiccups
  * add `-ns` for slow uefi TTYs
* separate login cookies for http / https
  * avoids an https login from getting accidentally sent over plaintext
  * sadly no longer possible to login with internet explorer 4.0 / windows 3.11
* tar/zip-download of hidden folders
* unpost filtering was buggy for non-ascii characters
* moving a deduplicated file on a volume where deduplication was since disabled
* improved the [linux 6.0.16](https://utcc.utoronto.ca/~cks/space/blog/linux/KernelBindBugIn6016) kernel bug [workaround](https://github.com/9001/copyparty/commit/9065226c3d634a9fc15b14a768116158bc1761ad) because there is similar funk in 5.x
* add custom text selection colors because chrome is currently broken on fedora
* blockdevs (`/dev/nvme0n1`) couldn't be downloaded as files
* misc fixes for location-based reverse-proxying
* macos dualstack thing

## other changes
* added a collection of [cursed usecases](https://github.com/9001/copyparty/tree/hovudstraum/docs/cursed-usecases)
* and [comparisons to similar software](https://github.com/9001/copyparty/blob/hovudstraum/docs/versus.md) in case you ever wanna jump ship

# 2023-0112-0515  `v1.5.6`  many hands

hello from warsaw airport (goodbye japan ;_;)
* read-only demo server at https://a.ocv.me/pub/demo/

## new features
* multiple upload handshakes in parallel
  * around **5x faster** when uploading small files
  * or **50x faster** if the server is on the other side of the planet
    * just crank up the `parallel uploads` like crazy (max is 64)
* upload ui: total time and average speed is shown on completion

## bugfixes
* browser ui didn't allow specifying number of threads for file search
* dont panic if a digit key is pressed while viewing an image
* workaround [linux kernel bug](https://utcc.utoronto.ca/~cks/space/blog/linux/KernelBindBugIn6016) causing log spam on dualstack
  * ~~related issue (also mostly harmless) will be fixed next relese 010770684db95bece206943768621f2c7c27bace~~

## new features
* image viewer now supports heif, avif, apng, svg
* [partyfuse and up2k.py](https://github.com/9001/copyparty/tree/hovudstraum/bin): option to read password from textfile

## bugfixes
* thumbnailing could fail if a primitive build of libvips is installed
* ssdp was wonky on dualstack ipv6
* mdns could crash on networks with invalid routes
* support fat32 timestamp precisions
  * fixes spurious file reindexing in volumes located on SD cards on android tablets which lie about timestamps until the next device reboot or filesystem remount

# 2022-1213-1956  `v1.5.3`  folder-sync + turbo-rust

* read-only demo server at https://a.ocv.me/pub/demo/

## new features
* one-way folder sync (client to server) using [up2k.py](https://github.com/9001/copyparty/blob/hovudstraum/bin/README.md#up2kpy) `-z --dr`
  * great rsync alternative when combined with `-e2ds --hardlink` deduplication on the server
* **50x faster** when uploading small files to HDD, especially SMR
  * by switching sqlite to WAL which carries a small chance of temporarily forgetting the ~200 most recent uploads if you have a power outage or your OS crashes; see `--help-dbd` if you have `-mtp` plugins which produces metadata you can't afford to lose
* location-based [reverse-proxying](https://github.com/9001/copyparty/#reverse-proxy) (but it's still recommended to use a dedicated domain/subdomain instead)
* IPv6 link-local automatically enabled for TCP and zeroconf on NICs without a routable IPv6
* zeroconf network filters now accept subnets too, for example `--z-on 192.168.0.0/16`
* `.hist` folders are hidden on windows
* ux:
  * more accurate total ETA on upload
  * sorting of batch-unpost links was unintuitive / dangerous
  * hotkey `Y` turns files into download links if nothing's selected
  * option to replace or disable the mediaplayer-toggle mouse cursor with `--mpmc`

## bugfixes
* WAL probably/hopefully fixes #10 (we'll know in 6 months roughly)
* repair db inconsistencies (which can happen if terminated during startup)
* [davfs2](https://wiki.archlinux.org/title/Davfs2) did not approve of the authentication prompt
* the `connect` button on the control-panel didn't work on phones
* couldn't specify windows NICs in arguments `--z-on` / `--z-off` and friends
* ssdp xml escaping for `--zsl` URL
* no longer possible to accidentally launch multiple copyparty instances on the same port on windows

named after [that other thing](https://en.wikipedia.org/wiki/Tower_of_Babel), not [the song](https://soundcloud.com/kanaze/babel-dimension-0-remix)
* read-only demo server at https://a.ocv.me/pub/demo/

## new features
* new protocols!
  * native IPv6 support, no longer requiring a reverse-proxy for that
  * [webdav server](https://github.com/9001/copyparty#webdav-server) -- read/write-access to copyparty straight from windows explorer, macos finder, kde/gnome
  * [smb/cifs server](https://github.com/9001/copyparty#smb-server) -- extremely buggy and unsafe, for when there is no other choice
  * [zeroconf](https://github.com/9001/copyparty#zeroconf) -- copyparty announces itself on the LAN, showing up in various file managers
    * [mdns](https://github.com/9001/copyparty#mdns) -- macos/kde/gnome + makes copyparty available at http://hostname.local/
    * [ssdp](https://github.com/9001/copyparty#ssdp) -- windows
  * commands to mount copyparty as a local disk are in the web-UI at control-panel --> `connect`
* detect buggy / malicious clients spamming the server with idle connections
  * first tries to be nice with `Connection: close` (enough to fix windows-webdav)
  * eventually bans the IP for `--loris` minutes (default: 1 hour)
* new arg `--xlink` for cross-volume detection of duplicate files on upload
* new arg `--no-snap` to disable upload tracking on restart
  * will not create `.hist` folders unless required for thumbnails or markdown backups
* [config includes](https://github.com/9001/copyparty/blob/hovudstraum/docs/example2.conf) -- split your config across multiple config files
* ux improvements
  * hotkey `?` shows a summary of all the hotkeys
  * hotkey `Y` to download selected files
  * position indicator when hovering over the audio scrubber
  * textlabel on the volume slider
  * placeholder values in textboxes
  * options to hide scrollbars, compact media player, follow playing song
  * phone-specific
    * buttons for prev/next folder
    * much better ui for hiding folder columns

## bugfixes
* now possible to upload files larger than 697 GiB
  * technically a [breaking change](https://github.com/9001/copyparty#breaking-changes) if you wrote your own up2k client
    * please let me know if you did because that's awesome
* several macos issues due to hardcoded syscall numbers
* sfx: fix python 3.12 support (forbids nullbytes in source code)
* use ctypes to discover network config -- fixes grapheneos, non-english windows
* detect firefox showing stale markdown documents in the editor
* detect+ban password bruteforcing on ftp too
* http 206 failing on empty files
* incorrect header timestamps on non-english locales
* remind ftp clients that you cannot cd into an image file -- fixes kde dolphin
* ux fixes
  * uploader survives running into inaccessible folders
  * middleclick documents in the textviewer sidebar to open in a new tab
  * playing really long audio files (1 week or more) would spinlock the browser

## other changes
* autodetect max number of clients based on OS limits
  * `-nc` is probably no longer necessary when running behind a reverse-proxy
* allow/try playing mkv files in chrome
* markdown documents returned as plaintext unless `?v`
* only compress `-lo` logfiles if filename ends with `.xz`
* changed sfx compression from bz2 to gz
  * startup is slightly faster
  * better compatibility with embedded linux
* copyparty64.exe -- 64bit edition for [running inside WinPE](https://user-images.githubusercontent.com/241032/205454984-e6b550df-3c49-486d-9267-1614078dd0dd.png)
  * which was an actual feature request, believe it or not!
* more attempts at avoiding the [firefox fd leak](https://bugzilla.mozilla.org/show_bug.cgi?id=1790500)
  * if you are uploading many small files and the browser keeps crashing, use chrome instead
    * or the commandline client, which is now available for download straight from copyparty
      * control-panel --> `connect` --> `up2k.py`

  * primarily for running copyparty on a phone and accessing it from another
  * optionally specify a path or password with `--qrl lootbox/?pw=hunter2`
  * uses the server's exteral ip (default route) unless `--qri` specifies a domain / ip-prefix
  * classic cp437 `▄` `▀` for space efficiency; some misbehaving terminals / fonts need `--qrz 2`
* new permission `G` returns the filekey of uploaded files for users without read-access
  * when combined with permission `w` and volflag `fk`, uploaded files will not be accessible unless the filekey is provided in the url, and `G` provides the filekey to the uploader unlike `g`
* filekeys are added to the unpost listing

## bugfixes
* renaming / moving folders is now **at least 120x faster**
  * and that's on nvme drives, so probably like 2000x on HDDs
* uploads to volumes with lifetimes could get instapurged depending on browser and browser settings
* ux fixes
  * FINALLY fixed messageboxes appearing offscreen on phones (and some other layout issues)
  * stop asking about folder-uploads on phones because they dont support it
  * on android-firefox, default to truncating huge folders with the load-more button due to ff onscroll being buggy
  * audioplayer looking funky if ffmpeg unavailable
* waveform-seekbar cache expiration (the thumbcleaner complaining about png files)
* ie11 panic when opening a folder which contains a file named `up2k`
  * turns out `<a name=foo>` becomes `window.foo` unless that's already declared somewhere in js -- luckily other browsers "only" do that with IDs

## bugfixes
* zfs on ubuntu 20.04 would reject files with big unicode names such as `148. Профессор Лебединский, Виктор Бондарюк, Дмитрий Нагиев - Я её хой (Я танцую пьяный на столе) (feat. Виктор Бондарюк & Дмитрий Нагиев).mp3`
  * usually not a problem since copyparty truncates names to fit filesystem limits, except zfs uses a nonstandard errorcode
* in the "print-message-to-serverlog" feature, a unicode message larger than one tcp-frame could decode incorrectly

* latest gzip edition of the sfx: [v1.0.14](https://github.com/9001/copyparty/releases/tag/v1.0.14#:~:text=release-specific%20notes)

## new features
* huge folders are lazily rendered for a massive speedup, #11
  * also reduces the number of `?tree` requests; helps a tiny bit on server load
* [selfdestruct timer](https://github.com/9001/copyparty#self-destruct) on uploaded files -- see link for howto and side-effects
* ban clients trying to bruteforce passwords
  * arg `--ban-pw`, default `9,60,1440`, bans for 1440min after 9 wrong passwords in 60min
  * clients repeatedly trying the same password (due to a bug or whatever) are not counted
  * does a `/64` range-ban for IPv6 offenders
  * arg `--ban-404`, disabled by default, bans for excessive 404s / directory-scanning
    * but that breaks up2k turbo-mode and probably some other eccentric usecases
* waveform seekbar [(screenshot)](https://user-images.githubusercontent.com/241032/192042695-522b3ec7-6845-494a-abdb-d1c0d0e23801.png)
* the up2k upload button can do folders recursively now
  * but only a single folder can be selected at a time, making drag-drop the obvious choice still
* gridview is now less jank, #12
* togglebuttons for desktop-notifications and audio-jingle when upload completes
* stop exposing uploader IPs when avoiding filename collisions
  * IPs are now HMAC'ed with urandom stored at `~/.config/copyparty/iphash`
* stop crashing chrome; generate PNGs rather than SVGs for filetype icons
* terminate connections with SHUT_WR and flush with siocoutq
  * makes buggy enterprise proxies behave less buggy
  * do a read-spin on windows for almost the same effect
* improved upload scheduling
  * unfortunately removes the `0.0%, NaN:aN, N.aN MB/s` easteregg
* arg `--magic` enables filetype detection on nameless uploads based on libmagic
* mtp modifiers to let tagparsers keep their stdout/stderr instead of capturing
  * `c0` disables all capturing, `c1` captures stdout only, `c2` only stderr, and `c3` (default) captures both
* arg `--write-uplog` enables the old default of writing upload reports on POSTs
  * kinda pointless and was causing issues in prisonparty
* [upload modifiers](https://github.com/9001/copyparty#write) for terse replies and to randomize filenames
* other optimizations
  * 30% faster tag collection on directory listings
  * 8x faster rendering of huge tagsets
* new mtps [guestbook](https://github.com/9001/copyparty/blob/hovudstraum/bin/mtag/guestbook.py) and [guestbook-read](https://github.com/9001/copyparty/blob/hovudstraum/bin/mtag/guestbook-read.py), for example for comment-fields on uploads
* arg `--stackmon` now takes dateformat filenames to produce multiple files
* arg `--mtag-vv` to debug tagparser configs
* arg `--version` shows copyparty version and exits
* arg `--license` shows a list of embedded dependencies + their licenses
* arg `--no-forget` and volflag `:c,noforget` keeps deleted files in the up2k db/index

  * delay starting the audiocontext until necessary
    * reduces cpu-load by 0.2% and fixes chrome claiming the tab is playing audio

# copyparty.exe

now introducing [copyparty.exe](https://github.com/9001/copyparty/releases/download/v1.4.0/copyparty.exe)!   only suitable for the rainiest of days ™

[first thing you'll see](https://user-images.githubusercontent.com/241032/192070274-bfe0bfef-2293-40fc-8852-fcf4f7a90043.png) when you run it is a warning to **«please use the [python-sfx](https://github.com/9001/copyparty/releases/latest/download/copyparty-sfx.py) instead»**,
* `copyparty.exe` was compiled using 32bit python3.7 to support windows7, meaning it won't receive any security patches
* `copyparty-sfx.py` uses your system libraries instead so it'll stay safe for much longer while also having better performance

so the exe might be super useful in a pinch on a secluded LAN but otherwise *Absolutely Not Recommended*

you can download [ffmpeg](https://ocv.me/stuff/bin/ffmpeg.exe) and [ffprobe](https://ocv.me/stuff/bin/ffprobe.exe) into the same folder if you want multimedia-info, audio-transcoding or thumbnails/spectrograms/waveforms -- those binaries were [built](https://github.com/9001/copyparty/tree/hovudstraum/scripts/pyinstaller#ffmpeg) with just enough features to cover what copyparty wants, but much like copyparty.exe itself (so due to security reasons) it is strongly recommended to instead grab a [recent official build](https://github.com/BtbN/FFmpeg-Builds/releases/download/latest/ffmpeg-master-latest-win64-gpl.zip) every once in a while

## and finally some good news

* the chrome memory leak will be [fixed in v107](https://bugs.chromium.org/p/chromium/issues/detail?id=1354816)
* and firefox may fix the crash in [v106 or so](https://bugzilla.mozilla.org/show_bug.cgi?id=1790500)
* and the release title / this season's codename stems from a cpp instance recently being slammed with terabytes of uploads running on a struggling server mostly without breaking a sweat 👍

# 2022-0818-1724  `v1.3.16`  gc kiting

* read-only demo server at https://a.ocv.me/pub/demo/
* latest gzip edition of the sfx: [v1.0.14](https://github.com/9001/copyparty/releases/tag/v1.0.14#:~:text=release-specific%20notes)

## bugfixes
* found a janky workaround for [the remaining chrome wasm gc bug](https://bugs.chromium.org/p/chromium/issues/detail?id=1354816)
  * worker-global typedarray holding on to the first and last byte of the filereader output while wasm chews on it
  * overhead is small enough, slows down firefox by 2~3%
  * seems to work on many chrome versions but no guarantees
    * still OOM's some 93 and 97 betas, probably way more 

## other changes
* disable `mt` by default on https-desktop-chrome
  * avoids the gc bug entirely (except for plaintext-http and phones)
  * chrome [doesn't parallelize](https://bugs.chromium.org/p/chromium/issues/detail?id=1352210) `crypto.subtle.digest` anyways

two browser-bugs in two hours, man i just wanna play horizon
* read-only demo server at https://a.ocv.me/pub/demo/
* latest gzip edition of the sfx: [v1.0.14](https://github.com/9001/copyparty/releases/tag/v1.0.14#:~:text=release-specific%20notes)

## bugfixes
* chrome randomly running out of memory while hashing files and `mt` is enabled
  * the gc suddenly gives up collecting the filereaders
  * fixed by reusing a pool of readers instead
* chrome failing to gc Any Buffers At All while hashing files and `mt` is enabled on plaintext http
  * this one's funkier, they've repeatedly fixed and broke it like 6 times between chrome 84 and 106
  * looks like it just forgets about everything that's passed into wasm
  * no way around it, just show a popup explaining how to disable multithreaded hashing

## new features
* upload-info (ip and timestamp) is provided to `mtp` tagparser plugins as json
* tagscanner will index `fmt` (file-format / container type) by default
  * and `description` can be enabled in `-mte`

## bugfixes
* [v1.3.12](https://github.com/9001/copyparty/releases/tag/v1.3.12) broke file-indexing on windows if an entire HDD was mounted as a volume

* latest gzip edition of the sfx: [v1.0.14](https://github.com/9001/copyparty/releases/tag/v1.0.14#:~:text=release-specific%20notes)

## new features
*but wait, there's more!*   not only do you get the [multithreaded file hashing](https://github.com/9001/copyparty/releases/tag/v1.3.11) but also --
* faster bootup and volume reindexing when `-e2ds` (file indexing) is enabled
  * `3x` faster is probably the average on most instances; more files per folder = faster
  * `9x` faster on a 36 TiB zfs music/media nas with `-e2ts` (metadata indexing), dropping from 46sec to 5sec
  * and `34x` on another zfs box, 63sec -> 1.8sec
  * new arg `--no-dhash` disables the speedhax in case it's buggy (skipping files or audio tags)
* add option `--exit idx` to abort and shutdown after volume indexing has finished

## bugfixes
* [u2cli](https://github.com/9001/copyparty/tree/hovudstraum/bin#up2kpy): detect and skip uploading from recursive symlinks
* stop reindexing empty files on startup
* support fips-compliant cpython builds
  * replaces md5 with sha1, changing the filetype-associated colors in the gallery view

* latest gzip edition of the sfx: [v1.0.14](https://github.com/9001/copyparty/releases/tag/v1.0.14#:~:text=release-specific%20notes)

## new features
* multithreaded file hashing! **300%** average speed increase
  * when uploading files through the browser client, based on web-workers
    * `4.5x` faster on http from a laptop -- `146` -> `670` MiB/s
    * ` 30%` faster on https from a laptop -- `552` -> `716` MiB/s
    * `4.2x` faster on http from android -- `13.5` -> `57.1` MiB/s
    * `5.3x` faster on https from android -- `13.8` -> `73.3` MiB/s
    * can be disabled using the `mt` togglebtn in the settings pane, for example if your phone runs out of memory (it eats ~250 MiB extra RAM)
  * `2.3x` faster [u2cli](https://github.com/9001/copyparty/tree/hovudstraum/bin#up2kpy) (cmd-line client) -- `398` -> `930` MiB/s
  * `2.4x` faster filesystem indexing on the server
  * thx to @kipukun for the webworker suggestion!

## bugfixes
* ux: reset scroll when navigating into a new folder
* u2cli: better errormsg if the server's tls certificate got rejected
* js: more futureproof cloudflare-challenge detection (they got a new one recently)

## other changes
* print warning if the python interpreter was built with an unsafe sqlite
* u2cli: add helpful messages on how to make it run on python 2.6

**trivia:** due to a [chrome bug](https://bugs.chromium.org/p/chromium/issues/detail?id=1352210), http can sometimes be faster than https now ¯\\\_(ツ)\_/¯

  * tag scanner
  * on windows: uploading to fat32 or smb
* toggle-button to sort folders before files (default-on)
  * almost the same as before, but now also when sorting by size / date
* repeatedly hit `ctrl-c` to force-quit if everything dies
* new file-indexing guards
  * `--xdev` / volflag `:c,xdev` stops if it hits another filesystem (bindmount/symlink)
  * `--xvol` / volflag `:c,xvol` does not follow symlinks pointing outside the volume
  * only affects file indexing -- does NOT prevent access!

## bugfixes

* latest gzip edition of the sfx: [v1.0.14](https://github.com/9001/copyparty/releases/tag/v1.0.14#:~:text=release-specific%20notes)

## new features

* some features no longer block new uploads while they're processing
  * `-e2v` file integrity checker
  * `-e2ts` initial tag scanner
  * hopefully fixes a [deadlock](https://www.youtube.com/watch?v=DkKoMveT_jo&t=3s) someone ran into (but probably doesn't)
    * (the "deadlock" link is an addictive demoscene banger -- the actual issue is #10)
* reduced the impact of some features which still do
  * defer `--re-maxage` reindexing if there was a write (upload/rename/...) recently
    * `--db-act` sets minimum idle period before reindex can start (default 10sec)
* bbox / image-viewer: add video hotkeys 0..9 to seek 0%..90%
* audio-player: add audio crossfeed (left-right channel mixer / vocal isolation)
* splashpage (`/?h`) shows time since the most recent write

## bugfixes
* a11y:
  * enter-key should always trigger onclick
  * only focus password box if in-bounds
  * improve skip-to-files
* prisonparty: volume labeling in root folders
* other minor stuff
  * forget deleted shadowed files from the db
  * be less noisy if a client disconnects mid-reply
  * up2k.js less eager to thrash slow server HDDs

## other changes
* show client's upload ETA in server log
* dump stacks and issue `lsof` on the db if a transaction is stuck
  * will hopefully help if there's any more deadlocks
* [up2k-hook-ytid](https://github.com/9001/copyparty/blob/hovudstraum/contrib/plugins/up2k-hook-ytid.js) (the overengineered up2k.js plugin example) now has an mp4/webm/mkv metadata parser

* latest gzip edition of the sfx: [v1.0.14](https://github.com/9001/copyparty/releases/tag/v1.0.14#:~:text=release-specific%20notes)

## new features
* `up2k.js`: **improved upload speeds!**
  * **...when there's many small files** (or the browser is slow)
    * add [potato mode](https://user-images.githubusercontent.com/241032/179336639-8ecc01ea-2662-4cb6-8048-5be3ad599f33.png) -- lightweight UI for faster uploads from slow boxes
    * enables automatically if it detects a cpu bottleneck (not very accurate)
  * **...on really fast connections (LAN / fiber)**
    * batch progress updates to reduce repaints
  * **...when there is a mix of big and small files**
    * sort the uploads by size, smallest first, for optimal cpu/network usage
      * can be overridden to alphabetical order in the settings tab
      * new arg `--u2sort` changes the default + overrides the override button
    * improve upload pacing when alphabetical order is enabled
      * mainly affecting single files that are 300 GiB + 
* `up2k.js`: add [up2k hooks](https://github.com/9001/copyparty/blob/hovudstraum/contrib/plugins/up2k-hooks.js)
  * specify *client-side* rules to reject files as they are dropped into the browser
  * not a hard-reject since people can use [up2k.py](https://github.com/9001/copyparty/blob/hovudstraum/bin/up2k.py) and whatnot, more like a hint
* `up2k.py`: add file integrity checker
  * new arg `-e2v` to scan volumes and verify file checksums on startup
  * `-e2vu` updates the db on mismatch, `-e2vp` panics
  * uploads are blocked while the scan is running -- might get fixed at some point
    * for now it prints a warning
* bbox / image-viewer: doubletap a picture to enter fullscreen mode
* md-editor: `ctrl-c/x` affects current line if no selection, and `ctrl-e` is fullscreen
* tag-parser plugins:
  * add support for passing metadata from one mtp to another (parser dependencies)
    * the `p` flag in [vidchk](https://github.com/9001/copyparty/blob/hovudstraum/bin/mtag/vidchk.py) usage makes it run after the base parser, eating its output
  * add [rclone uploader](https://github.com/9001/copyparty/blob/hovudstraum/bin/mtag/rclone-upload.py) which optionally and by default depends on vidchk

## bugfixes
* sfx would crash if it got the same PID as recently (for example across two reboots)

  * still can't figure out why chrome sometimes drops the mediasession
* bbox: don't attach click events to videos

  * shows a toast while loading huge filedrops to indicate it's still alive
* sfx: disable guru meditation unless running on windows
  * avoids hanging systemd on certain crashes
* logs the state of all threads if sqlite hits a timeout

* latest gzip edition of the sfx: [v1.0.14](https://github.com/9001/copyparty/releases/tag/v1.0.14#:~:text=release-specific%20notes)

## new features
* detect + recover from cloudflare ddos-protection memes during upload
  * while carefully avoiding any mention of "DDoS" in the JS because enterprise firewalls do not enjoy that
* new option `--favico` to specify a default favicon
  * set to `🎉` by default, which also enables the fancy upload progress donut 👌
* baguettebox (image/video viewer):
  * toolbar button `⛶` to enter fullscreen mode (same as hotkey `F`)
  * tap middle of screen to show/hide toolbar
  * tap left/right-side of pics to navigate prev/next
  * hotkeys `[` and `]` to set A-B loop in videos
    * and [URL parameters](https://a.ocv.me/pub/demo/pics-vids/#gf-e2e482ae&t=4.2-6) for that + [initial seekpoint](https://a.ocv.me/pub/demo/pics-vids/#gf-c04bb0f6&t=26s) (same as the audio player)

## bugfixes
* when a tag-parser hits the timeout, `pkill` all its descendants too
  * and a [new mtp flag](https://github.com/9001/copyparty/#file-parser-plugins) to override that; `kt` (kill tree, default), `km` (kill main, old default), `kn` (kill none)
* cpu-wasting spin while waiting for the final handful of files to finish tag-scraping
* detection of sparse-files support inside [prisonparty](https://github.com/9001/copyparty/tree/hovudstraum/bin#prisonpartysh) and other strict jails
* baguettebox (image/video viewer):
  * crash on swipe during close
* didn't reset terminal color at the end of `?ls=v`
* don't try to thumbnail empty files (harmless but dumb)

## other changes
* ux improvements
  * hide the uploads table until something happens
* bump codemirror to 5.65.6

  * **android fix:** external sdcard seems to be UCS-2 which can't into emojis
* **upload:** accurate detection of support for sparse files

* detect and warn if filesystem was expected to support sparse files yet doesn't

## bugfixes

* latest gzip edition of the sfx: [v1.0.14](https://github.com/9001/copyparty/releases/tag/v1.0.14#:~:text=release-specific%20notes)

## new features
* improved support for filesystems without sparse files (fat32, exfat, hpfs)
  * the server no longer preallocates the whole file with zeroes before upload can start
  * so you can now finally run copyparty on your android phone or tablet and upload to the sd-card instead of the internal storage
  * however upload speed will suffer a bit (limited to a single tcp connection doing one chunk at a time)
* safety profiles; arguments `-s`, `-ss`, and `-sss` are aliases/presets for other safety-related arguments
  * `-s` reduces attack surface from potentially dangerous software by disabling thumbnails, audio transcoding, ffmpeg, pillow, vips
  * `-ss` also prevents js-injection, accidental move/deletes, broken symlinks, and enables enterprise-grade security (return 404 on 403)
  * `-sss` also enables logging to disk and does a scan for dangerous symlinks at startup (possibly expensive)
* ux improvements
  * a11y jumpers -- hit tab + enter to jump straight to files/folders
  * hotkey `Y` to download currently playing song / vid / pic
  * button to reset the hidden columns
  * new themes "hacker" and "hi-con"

## bugfixes
* spinlock if a client disconnects in the middle of an up2k handshake
* ftp server couldn't persist metadata when multiprocessing was enabled (`-j 0`)
* cut/paste (move) files between filesystems
* allow `Connection: keep-alive` on HTTP/1.0
* stray `[` appeared at the start of logfiles in the textviewer
* misleading log message when a completed upload expires from registry and `-e2d` was not set

## other changes
* the basic uploader adds the `.PARTIAL` suffix while uploading (like up2k)
* added type hints / mypy checking
* upgrade deps (markedjs, codemirror)
* ux improvements
  * delay spinners a bit
  * instant feedback when switching folders
  * a11y outlines in up2k ui

* `search:` button to load more search results, starting at 125 instead of 1000, now much better on slow PCs
* `search:` immediately perform a search when the enter key is pressed
* `uploader:` optimal column sizing in the uploader depending on which tab is selected (done/busy/queued)
* `uploader:` new option `--turbo` to change the default settings of the turbo-mode in the uploader
  * `0` (default) is the old behavior, `1` disables the warning when enabling turbo, `2` enables turbo, `3` also disables the datecheck
  * see the tooltip in the settings tab for more info; basically it skips the file contents verification and instead relies on filesize and timestamp to guess if a file was uploaded already, useful for massive upload batches that got interrupted

## bugfixes
* `httpd:` a theoretical XSS opening -- copyparty would echo bad requests as html
  * it still does that, but now with plaintext content-type
  * was mostly-harmless -- can't really think of a way to exploit it since it'd only happen on invalid HTTP requests
* `httpd:` better errorhandling on invalid requests in general
* **windows-only:** `httpd:` deadlocks when trying to access files with illegal filenames on windows
  * files containing characters `:*<|>"/?\` or names starting with `con.`, `prn.`, `aux.`, `nul.`
  * for example `aux.c` when unpacking the linux source code on a flashdrive and plugging it into a windows rig
* **windows-only:** `database:` deadlock if a search was done during the initial filesystem scan
* `database:` deadlock if an upload was done during a filesystem scan (either initial or periodic rescan)
* `client:` javascript crash when linking someone an audio URL and they'd never visited before
* `client:` ignore bugs in the developer console (in future versions of chrome)
* `uploader:` timestamps of zero-byte uploads were not set
* `database:` skip busy files during a filesystem rescan
* `media player:` sending artist / title info to the OS broke at some point

## other changes
* changed the themes to use css variables for colors, making it way easier (hopefully) to make your own themes
* mention [chrome issue 1317069](https://bugs.chromium.org/p/chromium/issues/detail?id=1317069) in the readme
* improved the `--help` text

* latest gzip edition of the sfx: [v1.0.14](https://github.com/9001/copyparty/releases/tag/v1.0.14#:~:text=release-specific%20notes)

# new features
* quoted searches, for stuff like "[more more more](https://www.youtube.com/watch?v=bgVRGmOK4SM)"
* upload ETA in the browser window title
* audio-player stays open on navigation
* thumbnails indicating whether clicking an audio file will start playing it (when the audio-player is open) or not
* mtp plugin [image-noexif](https://github.com/9001/copyparty/blob/hovudstraum/bin/mtag/image-noexif.py) removes EXIF from uploaded images
* when running on windows; disable quickedit so cmd.exe doesn't pause the server if you accidentally click the console window
  * option `--keep-qem` disables disabling it

# bugfixes
* forcing specific compression levels using volume-flag `pk`
* mtp plugins [audio-bpm](https://github.com/9001/copyparty/blob/hovudstraum/bin/mtag/audio-bpm.py) and [audio-key](https://github.com/9001/copyparty/blob/hovudstraum/bin/mtag/audio-key.py) couldn't open files with mojibake / corrupt filenames

# other changes
* uploading files by dragging them into the browser using a computer from before 2009 should have zero delay now
* workaround for a chrome bug (appeared in chrome 96, fixed in 98) where dragging a link would activate the uploader
* mention in the readme that enabling the audio equalizer, with all values at zero, makes gapless albums fully gapless
* better error messages in the [standalone up2k upload client](https://github.com/9001/copyparty/blob/hovudstraum/bin/up2k.py)
* mirror at [gitlab](https://gitlab.com/9001/copyparty/-/releases) since github has been down a lot lately

# 2021-1120-0127  `v1.1.3`  CoreAudioFormat aight yeah okay

not super important but recommended
* latest gzip edition of the sfx: [v1.0.14](https://github.com/9001/copyparty/releases/tag/v1.0.14#:~:text=release-specific%20notes)

# known problems
* **streaming compression of uploads:** optional arguments to volume-flag `pk` don't work, so you can only force-enable compression without specifying an exact algorithm (gz/xz) and level (0-9), instead letting the client choose a preference -- default is `gz,9`

# new features
* automatically enable transcoding for unsupported audio codecs (aac/m4a in some chromium builds)
* audio-player: gapless albums are even closer to gapless now
  * especially on iOS devices as they generally ignore preload hints
  * on all other browsers, opus appears to perform better than other codecs (noice)
* added a tooltip delay, and a hint next to the mouse-cursor for instant feedback
* new button in the control-panel, `enable k304` which kills the http connection on every `304 Not Modified` response
  * avoids a bug in some browsers (ie11) and webproxies (squid maybe?) which *sometimes* get stuck, expecting data after the header
* enable up2k-registry serialization when running without `-e2d` / sqlite, so incomplete uploads can be resumed after a server restart
* include both the hex and base64 sha512 representations in upload responses
* [standalone up2k upload client](https://github.com/9001/copyparty/blob/hovudstraum/bin/up2k.py): option `--ok` ignores any inaccessible files/folders and starts the upload anyways
* option `--rsp-slp` adds a synthetic delay to client responses

# bugfixes
* up2k-webclient: could crash if two browser-tabs uploaded the same chunk simultaneously
  * mostly harmless but you'd have to reload the tab to fix it + manually resume the upload
* buggy behavior when python was compiled without sqlite3 (default on freebsd)
  * memory usage would grow infinitely as more files were uploaded
  * exceptions sent to the client when trying to search
* add timeouts to FFmpeg operations, preventing invalid files from eating the `--th-mt` threads
  * 10 seconds for filetype / metadata parsing
  * 60 seconds (`--th-convt`) for thumbnails and audio transcoding
* up2k-webclient: fix an inconvenient priority inversion when turbo/yolo was enabled

# 2021-1112-2208  `v1.1.2`  mind the gap

* latest important update: **this one**? kind of
* latest gzip edition of the sfx: [v1.0.14](https://github.com/9001/copyparty/releases/tag/v1.0.14#:~:text=release-specific%20notes)

# new features
* navigate into textfiles using hotkeys (`v, k`)
* close various UI elements by repeatedly hitting the Escape key
* doubleclick files/folders to open them (in the grid view, when multiselect is enabled)
* `--s-wr-slp` sets a delay between socket writes, simulates a slow network during downloads
* `--s-wr-sz` sets socket write size, default 256 KiB (was hardcoded 32 KiB until now)
  * this increase download speed by ~50% (to around 3 GiB/s) when running on windows / where sendfile is unavailable

# bugfixes
* when uploading two files with the same name and size, only the first file got uploaded
  * so now it's also possible to upload the same files you just searched for without the refresh jank
  * discovered thanks to rockylinux serving the same package in multiple pools, nice
* when full-preload is enabled, also do regular preloading so the decoder has a chance to prepare (fixes gapless playback)
  * and kill the preloaders if they don't finish in time so free up network
* additional preloading fixes for ogv.js, only affecting **apple devices** when playing ogg/vorbis/opus audio:
  * disable full-preload since ogv skips the browser cache somehow
  * swap between the ogv instances to preserve cached audio
  * still a bit of silence left between tracks as the decoder boots up but that is the price you have to pay for using proprietary garbage
* `ctrl-a` now only selects the text within the focused codeblock in text documents
* minor correctness fix regarding chunked uploads
* avoid crc32 collisions in filenames
  * affected the media player and file selection, but [was unlikely to happen](https://i.stack.imgur.com/u4DeG.png)

# other changes
* prefer fpool on linux as well, since btrfs and zfs (and probably others) perform better with it

# 2021-1108-2139  `v1.1.1`  firefox v92 broke the clipboard

* latest important update: [v1.0.8](https://github.com/9001/copyparty/releases/tag/v1.0.8)
* latest gzip edition of the sfx: [v1.0.14](https://github.com/9001/copyparty/releases/tag/v1.0.14#:~:text=release-specific%20notes)

## upgrade notes
* clipboard protocol changed -- `F5` your browser-tabs before moving any files with `ctrl-x` + `ctrl-v`

# new features
* option to preload the entire next song when approaching end-of-track
  * new button in the audioplayer options panel
  * should help with spotty but fast connections
  * *(probably does more harm than good on slow ones)*

# bugfixes
* [firefox v92 broke clipboard sync](https://bugzilla.mozilla.org/show_bug.cgi?id=1740144), so moving files between browser-tabs didn't work too well

# other changes
* adjusted the fallback spectrogram generator to better match the preferred one

* latest gzip edition of the sfx: [v1.0.14](https://github.com/9001/copyparty/releases/tag/v1.0.14#:~:text=release-specific%20notes)

## upgrade notes
* you can use `--no-reload`, `--no-acode`, `--no-athumb` to disable the new features described below

# new features
* **audio transcoder**
  * hipster audio formats are transcoded to opus on-demand
    * `aac` `m4a` `flac` `alac` `mp2` `ac3` `dts` `wma` `ra` `wav` `aif` `aiff` `au` `alaw` `ulaw` `mulaw` `amr` `gsm` `ape` `tak` `tta` `wv`
  * because kipu wanted to play his `.au` bangers from 1993
  * needs FFmpeg and FFprobe, can be disabled with `--no-acode`
* **audio spectrograms**
  * are shown as thumbnails for audio files
  * supported formats: same as transcoder + `mp3` `ogg` `opus`
  * needs FFmpeg and FFprobe, can be disabled with `--no-athumb`
* **textfile viewer**
  * with syntax hilighting
    * can be disabled by deleting `web/deps/prism.js.gz` or building the sfx with `no-hl`
  * and list of textfiles in the navpane; toggle with hotkey `v`
* **navpane context dock**
  * snap parent folders into a panel to keep track in huge folders
  * toggle-button to disable it in the navpane toolbar
* **config reload**
  * SIGUSR1 reloads the config files
    * the [systemd example](https://github.com/9001/copyparty/blob/hovudstraum/contrib/systemd/copyparty.service) has been updated with `ExecReload`
  * only does accounts, volumes, and volflags -- so any changes to args still require a full restart
  * also available as a button in the control panel
    * can be disabled with `--no-reload`
* option to specify args (command-line arguments) in the config file
* url parameter `?txt` to return file as utf-8 text
  * or `?txt=iso-8859-1` to set a specific encoding
* url parameter `?mime=text/html;charset=shift_jis` to request a specific response mimetype
* [service script for freebsd](https://github.com/9001/copyparty/blob/hovudstraum/contrib/rc/copyparty), thx @kipukun 

# bugfixes
* [standalone up2k upload client](https://github.com/9001/copyparty/blob/hovudstraum/bin/up2k.py) was showing https warnings with `-td`
* trailing newline missing in `?ls=t` and `?ls=v`
* add a bunch of known mimetypes to help ms-windows a bit
* lowercase all content-type charsets (firefox became case-sensitive at some point)
* example for giving multiple users the same permission-set using config files did not actually work

# other changes
* navpane is enabled by default on sufficiently large displays
* audio-player preload increased from 10 to 20 sec, giving the opus transcoder some time
* finally removed the deprecated `-e2s` option after 9 months (replaced by `-e2ds`)

# 2021-1029-2237  `v1.0.14`  party donuts

* latest important update: [v1.0.8](https://github.com/9001/copyparty/releases/tag/v1.0.8)
* latest gzip edition of the sfx: **this ver!**

## argv changes
* `--th-mt 0` no longer means «*use all CPU cores*», however using all cores is (and was) the default when leaving it unset
* `--re-int` no longer serves a purpose and was removed (it is automatically inferred)
* `--no-mtag-mt` was replaced by `--mtag-mt 1` to allow setting exact core counts

## new features
![copyparty-donut](https://user-images.githubusercontent.com/241032/139513444-c22fc17a-6f44-4308-9cb0-ab191e40660b.png)
* up2k tab (and favicon) become a donut / progress-ring while uploading / searching
  * favicon becomes ETA when less than 99sec remains and ETA is sufficiently stable
* tag scanning is now multithreaded for recent uploads as well, like the initial scan is/was
* url parameter `?ls=t` returns a plaintext directory listing, and `?ls=v` adds terminal colors
* less cpu wakeups! *conserve electricity and be power smart :^)*
* add refresh and logout buttons to the control-panel
* try to catch and warn about some common config mistakes
* when launched without arguments: try to use port 80 and 443 by default on windows (and when running as root)

## bugfixes
* couldn't delete empty folders
* spacebar now triggers the OK/Cancel buttons in modal popups
* navpane didn't have locale-aware sorting like the file listing does
* uploading a blank file would glitch the browser tab until the next page refresh
* the [standalone up2k client](https://github.com/9001/copyparty/blob/hovudstraum/bin/up2k.py) tried to mimic rsync behavior for source folder selection but had it the other way around
* if files were deleted while scanning for tags, the file hash was permanently marked as not having tags
* if some endpoints fail to bind, don't print them as "available" during startup
* navpane scroll glitch when loading new folders
* toast-positioning in ie11

## other changes
* truncate file "extensions" longer than 16 characters
* remove the multiprocessing warning on startup since it's mostly confusing
* mention selinux (fedora/centos/rhel-specific) setup steps in the systemd example
* new cheatcode in the javascript repl (bottom-left pi symbol) which turns all file links into download links

## release-specific notes
this release includes two additional sfx builds:
* [copyparty-enterprise.py](https://github.com/9001/copyparty/releases/download/v1.0.14/copyparty-enterprise.py) was built with `./scripts/make-sfx.sh re no-sh no-dd no-ogv`, removing `ogv` (the iOS ogg/opus/vorbis audio decoder) and `dd` (the audio-tray mouse cursor) to save some space
* [copyparty-sfx-gz.py](https://github.com/9001/copyparty/releases/download/v1.0.14/copyparty-sfx-gz.py) was built with `./scripts/make-sfx.sh re no-sh no-dd no-ogv no-cm gz`, also removing `cm` (the codemirror-based markdown editor), but more importantly using gzip compression rather than the usual bzip2, mostly useful for smoketests on feature-reduced python builds and embedded platforms

for future releases, you can use a script to automatically grab the latest sfx and create the two additional builds:
* download and run [copyparty-repack.sh](https://github.com/9001/copyparty/blob/hovudstraum/scripts/copyparty-repack.sh) on either linux, macos, or windows-msys2
* the two additional builds in this release are `sfx-ent/copyparty-sfx.py` and `sfx-lite/copyparty-sfx-gz.py` -- see [sfx-repack](https://github.com/9001/copyparty#sfx-repack) for more info

* latest gzip edition of the sfx: [v0.11.18](https://github.com/9001/copyparty/releases/tag/v0.11.18)

## new features
* search results are now shareable URLs
* optionally provide a filename when uploading with PUT or `?raw` POST
  * add a trailing slash to the URL to autogenerate a filename like before
  * and `?raw` POST without content-type is now allowed
* file-listing is refreshed when all up2k uploads complete
* new option `--ign-ebind` to continue startup even if one of the IPs / ports couldn't be listened on
* new option `--ign-ebind-all` to run even if copyparty can't receieve any connections at all
  * maybe useful for monitoring folders and hashing new files on a timer or something

## bugfixes
* unpost in jumpvols (inside `/foo/bar/` if `/foo/` and `/foo/bar/qux/` are volumes)
* u2cli: aggressive flushing to show uploaded files in realtime

## other changes

* latest gzip edition of the sfx: [v0.11.18](https://github.com/9001/copyparty/releases/tag/v0.11.18)

## breaking changes
* the argument `--no-hash` and volume-flags `dhash`, `ehash` (booleans) have been replaced with regex patterns; continue reading below

## new features
* optional favicon! configurable client-side in the `[⚙️]` config tab
  * the selected favicon is remembered per-server (good for keeping track of tabs)
* new argument `--no-idx '\.iso$'`, also available as volume-flag `[...]:c,noidx=\.iso$`
  * every filepath matching the given regex (`iso$`) will be ignored/skipped during indexing
  * uses OS-defined separators, so use `\\` as path-separator on windows
* "new" argument `--no-hash foo` and volume-flag `[...]:c,nohash=foo`
  * like `--no-idx`, but it only skips the file-contents indexing, so filename/path/size is still searchable
  * this replaces the boolean `--no-hash` and volume-flags `dhash`, `ehash`

## bugfixes
* fix ui race-condition (mkdir with navpane closed)
* mkdir was broken on python 2.7 since [v0.12.1 (july 28)](https://github.com/9001/copyparty/releases/tag/v0.12.1)
* try to support some buggy python builds (invalid ffi symbols)

* up2k: fully parallelized handshakes and uploads
  * uploading smol files is way faster now
  * some files may temporarily display as "failed" until all uploads complete
* browser: `mkdir` and `msg` can be used during uploads (no longer does a full page reload)
* up2k: option to keep destination files open during uploads (fd pool)
  * on windows: default-ON, due to Microsoft Defender "real-time protection" being hella expensive
  * on linux/macos: default-OFF, but can be enabled with `--use-fpool` for things like nfs
* up2k: new option `--no-symlink` to fully dupe files instead of adding symlinks
* add minimal support for some more eccentric browsers (including Hv3)

## bugfixes
* up2k: check all dupes for a matching filesystem path
  * prevents duplicate symlinks if the same dupe is repeatedly uploaded to the same place
* don't crash the tag collector thread if there are invalid tags
* up2k-client: don't DDoS the server if the http response is invalid
* when running without `-e2d`, recently uploaded files could not be deleted
* on windows, absolute filesystem-paths could appear in exceptions sent to the client
* misc url escaping fixes, mostly regarding files/folders where name contains `?`
* sort-order being reset if you visit an empty folder

## other changes
* moved the up2k fence-toggle into the settings pane since probably nobody uses it
* readme: add a section on recovering from [client crashes](https://github.com/9001/copyparty#client-crashes)
  * firefox (the whole browser and all its tabs) can crash during upload

# 2021-0918-2241  `v1.0.4`  early bird gets the bugs

* latest important update: [v1.0.3](https://github.com/9001/copyparty/releases/tag/v1.0.3)
* latest gzip edition of the sfx: [v0.11.18](https://github.com/9001/copyparty/releases/tag/v0.11.18)
* if upgrading from v0.11.x or before, see [v0.12.4](https://github.com/9001/copyparty/releases/tag/v0.12.4)

## bugfixes
* folders and volumes being out-of-order in the initial listing
* it was possible to shrink the navpane so much that the shrink/grow buttons disappeared

## other changes

# 2021-0918-1550  `v1.0.3`  unlisted

* latest important update: **this one**
* latest gzip edition of the sfx: [v0.11.18](https://github.com/9001/copyparty/releases/tag/v0.11.18)
* if upgrading from v0.11.x or before, see [v0.12.4](https://github.com/9001/copyparty/releases/tag/v0.12.4)

## known bugs
* on phones, it is *possible* to make the navpane so small that the resize buttons disappear
  * happens if you navigate into a folder 7+ levels deep, reduce the navpane size so the `a` button is barely visible, then disable `a`
  * **fix:** open the js prompt (click the bottom-left `π`) then execute `,.` (comma dot) and click `reset settings`

## new features
* new permission `g`: read-access only if you know the full URL to a file; folder contents are hidden, cannot download zip/tar
* new volume flag `fk`: generate per-file accesskeys, which are then required by `g` users to access files, making it harder to bruteforce URLs
  * users with full read-access can see the accesskeys appended to the URLs when browsing folders
* [wget.py](https://github.com/9001/copyparty/blob/hovudstraum/bin/mtag/wget.py): download files to the copyparty server by POSTing file URLs in the web-UI
* show a login prompt on 404/403 pages
* option to disable wordwrap in the navpane

## bugfixes
* loss of access to anon-read/write folders after logging in
  * affected filesearch, regular searching, and volume listings
* more aggressively `no-cache`, preventing cloudflare from eating api calls
* after deleteing all files inside a folder, don't delete the folder itself
  * was intended behavior but fairly confusing
* don't reshow tooltips when alt-tabbing
* accessibility: always hilight focused things
* markdown-editor modification poller doesn't cause performance issues after having a document open for several months
* mtp plugins [audio-bpm.py](https://github.com/9001/copyparty/blob/hovudstraum/bin/mtag/audio-bpm.py) and [audio-key.py](https://github.com/9001/copyparty/blob/hovudstraum/bin/mtag/audio-key.py) explicitly asks for just the first audio stream, which prevents ffmpeg from transcoding video (nice)

## other changes
* updated some web-deps
  * marked: `v1.1.0` -> `v3.0.4` (with modifications)
  * easymde: `v2.14.0` -> `v2.15.0` (with modifications)
  * codemirror: `v5.59.3` -> `v5.62.3` (with modifications)
  * hashwasm: `v4.7.0` -> `v4.9.0`
* easymde uses the external `marked.js` to save some space
* README.md has the same maxwidth as in the viewer/editor
* show a toast if there's an unhandled promise reject
* markdown-editor shows the current line number
* cfssl.sh (certificate generator) asks for fqdn instead of inventing something
* sfx binaries try to use python3 explicitly since a lot of distros don't have a /usr/bin/python at all

* if upgrading from v0.11.x or before, see [v0.12.4](https://github.com/9001/copyparty/releases/tag/v0.12.4)

## new features
* click an open tab to close it (thx daniiooo)

## bugfixes
* multipart POSTs could get incorrectly rejected with `protocol error after field value`
  * had a `0.14%` chance of happening (worst-case; 1400 mtu, 2 offsets)
  * affected stuff like saving markdown documents, renaming files, ...
  * did **not** affect file uploads, and reverseproxy probably helped prevent it
* filedrop UI could let you try to upload/search without the necessary permissions
  * purely cosmetic, would immediately fail with a slightly cryptic error message
* apply a different equalizer tuning for some browsers
  * some permutations of chrome and win10, and also some phones, have incorrect Q scaling at higher frequencies, causing treble to be massively boosted
  * now tries to detect this by sampling the frequency response at 15khz and setting different gains (less dangerous than touching Q)

## other changes
* search ui does not initiate searches as eagerly if the textbox has a very short value
  * helps prevent overloading slow browsers with accidental wildcard searches

see [v0.12.1](https://github.com/9001/copyparty/releases/tag/v0.12.1) upgrade-notes regarding new opt-out features

## upgrade notes
* new argument `--unpost 0` (and/or `--no-del`) disables the new unpost feature
* your up2k databases will upgrade from v4 to v5; backups are made automatically
  * v5 DBs require copyparty v0.12.3 or newer, so use the backups for older versions

  * can be disabled by setting `--unpost 0` or with `--no-del`

## bugfixes
* deleting single files (metadata could persist in db)
* `--ls` broke in v0.12.1
* toasts with `<pre>` tags had massive margins
* hopefully fix a bug where malicious POSTs through an nginx reverse-proxy could put the connection in a bad state, causing the next legit request to fail with bad headers

## other changes
* uploader-ip and upload-time is stored in the database
  * but only viewable through an sqlite3 shell;
    `sqlite3 .hist/up2k.db 'select ip, rd, fn from up where ip'`

# 2021-0718-2122  `v0.11.42`  in case of tags

* latest important update: [v0.11.20](https://github.com/9001/copyparty/releases/tag/v0.11.20) (but skip right to this version)
* recent maybe-important updates:
  * [v0.11.42](https://github.com/9001/copyparty/releases/tag/v0.11.42) (this ver) if you have `-mtp` parsers *and* use Mutagen to read tags
  * [v0.11.41](https://github.com/9001/copyparty/releases/tag/v0.11.41) if running as a service with `-lo`
  * [v0.11.33](https://github.com/9001/copyparty/releases/tag/v0.11.33) fixes stability in the uploader client
  * [v0.11.32](https://github.com/9001/copyparty/releases/tag/v0.11.32) fixes a case of filesystem paths being unmasked
  * [v0.11.28](https://github.com/9001/copyparty/releases/tag/v0.11.28) fixes crash if no accounts are defined
* latest gzip edition of the sfx is [v0.11.18](https://github.com/9001/copyparty/releases/tag/v0.11.18)

## new features
* if Mutagen fails to read a file, it retries with FFprobe
* `--no-mtag-ff` bans all use of FFprobe to read tags
* hotkeys `i/k` now ensure the active folder stays in-view

## bugfixes
* tag search was case-sensitive in some cases (most importantly `key>=1a` did not work as intended)
* advanced-search would break if search terms were double-space separated
* the preferred key-notation did not apply to search results (did rekobo-alnum instead)
* tooltips for column headers didn't work for newly-hidden columns
* no more surprise tooltips when switching tabs

all these changelogs are sorted by importance btw so here's the least important bugfix (since it doesn't affect anyone i know)
* codec/format info was not collected from Mutagen when scanning audio files
  * this broke `mtp` (external metadata parsers)
  * you avoided this issue by not having Mutagen installed, and/or by using `--no-mutagen`
  * if you *were* using Mutagen to collect tags, you can do a single run with `-e2tsr` for a full rescan if you care

* combine the mkdir/newdoc/msg tabs on narrow screens
* sd-notify support to properly use copyparty as a systemd service
  * other units which `After=copyparty` will be delayed until copyparty is ready to accept connections
  * updated the [unit example](https://github.com/9001/copyparty/blob/master/contrib/systemd/copyparty.service) with the changes (`Type=notify` and `SyslogIdentifier=copyparty`)
* markdown editor hotkeys now work properly on dvorak keyboards
  * the hotkeys use the qwerty layout which seems to be preferred according to stackoverflow

## bugfixes
* clean shutdown on SIGINT and SIGTERM
  * previously, when running as a sysv/systemd service, a `service stop` would lose:
    * lots of log messages when using `-lo`
    * information about incomplete uploads for the past 30 seconds

## other changes
* lots of new tooltips with hotkeys info
  * also explains the cryptic codec/bitrate columns
  * and iphones can now hide tooltips by tapping them since safari is safari
* increased up2k snapshot interval from 30sec to 5min now that SIGTERM is a clean shutdown
* finally found something the `zip_crc` mode is good for: supporting PKZIP v2.04g from october 1993 (absolutely worth)

* latest gzip edition of the sfx is [v0.11.18](https://github.com/9001/copyparty/releases/tag/v0.11.18)

## new features
* faster http replies! reduced the time to establish new connections, so:
  * up to 25% faster round-trip time on short http requests with `-j1` (server-default), but more importantly...
  * up to 3.3x faster with `-j4` (now almost equal to `-j1`) and a single client doing stuff, but wait it gets better:
  * up to 6.6x faster with `-j4` and multiple clients hammering the server
  * but note that higher `-j` values adds more connection latency in exchange for processing power, https://en.wikipedia.org/wiki/Thundering_herd_problem
* discard log messages early when `-q` is set without `-lo`, giving better multiprocessing performance

## bugfixes
* fix general loss of centos7 support (TLnote: early 2.7 versions) introduced in [v0.11.30](https://github.com/9001/copyparty/releases/tag/v0.11.30)
  * also fixed downloading folders as zip-files which centos7 never could

## other changes
* `-j1` will be forced for python 2.7 because it cannot pickle tcp servers
* accessing `?stack` works on any url as long as you're admin *somewhere*
* the `-j` loadbalancer messages are gone because the loadbalancer is gone
  * should give a teeny-tiny performance boost to multiprocessing on uploads

* latest gzip edition of the sfx is [v0.11.18](https://github.com/9001/copyparty/releases/tag/v0.11.18)

## new features
* `turbo button` in the settings panel for superfast resume of massive uploads 
  * good for when you were in the middle of uploading 100'000 files and had to restart for some reason
  * comes at a serious cost: files will be skipped as long as they exist on the server with the right filesize, even if they could be incomplete uploads or are otherwise different from your local files, so you should do a "verification pass" by disabling turbo + refreshing + redoing the upload once you make it through
  * when combined with the new `date-chk` button it *should* notice and resume incomplete uploads but please do the verification pass anyways
  * all of this is explained in the tooltip for the button so idk why im putting it here too
* `-lo` enables xz-compressed logging to file in addition to printing to the console
  * with logrotate if the filename contains date-format-strings (like `%Y-%m-%d`)
  * when combined with `-q` it disables console-logging and only logs to file, gives a tiny speed boost depending on OS
  * also cleans up a few places with plain prints instead of the threadsafe pretty ones
* the volume-flags summary on startup now also print *which* volume they're talking about

## bugfixes
* `dir.txt` inside the thumbnails folder could be downloaded; possibly bad since it contains absolute-paths from the host filesystem
* [v0.11.31](https://github.com/9001/copyparty/releases/tag/v0.11.31) added parallel handshakes which could cause files to checksum and upload out-of-order, fixed
  * this also uncovered another UI-crash in the up2k client (nice) which is now also fixed separately
* a few more cases of recursive symlinks are detected and defused
  * symlink pointing to its own folder when creating a tar/zip
  * initial directory scanning (`-e2ds`)
    * initial directory scanning is now a tiny bit slower, sorry
* `-nw` didn't apply to PUT uploads
* more invalid requests get a sensible-ish reply stating what the client did wrong

## bugfixes

  * fixes one of the v0.11.30 known-bugs but still no idea what that other thing was, something about "bad file descriptor" right before a power outage so the logs are lost, shoganai
* race conditions in the up2k-server which couldn't be hit before parallel handshakes was added

* latest gzip edition of the sfx is [v0.11.18](https://github.com/9001/copyparty/releases/tag/v0.11.18)

## known bugs
* if an upload is paused by setting `parallel uploads` to `0` in the UI...
  * ...for "about an hour", it *might* be unable to resume
  * ...for 6 hours or more, it is **definitely** unable to resume

unless the upload was paused for 6 hours or more, it can probably be resumed by refreshing the website and restarting the upload ("probably" because haven't been able to reproduce)

## new features
* up2k-client: 100x faster initialization when adding lots of files
* cachebuster to force chrome to use the correct js/css files since it ignores the no-cache header
* make `-nw` apply to more stuff (up2k skips creating files)

## bugfixes
* up2k-client:
  * fix crash caused by parallel uploads running far ahead, ui trying to update stuff it already purged
    * mostly problematic when uploading lots of small files mixed with slightly-larger files
  * general robustness
    * recover from tcp/dns issues during chunk-uploads
    * recover from antivirus yanking files mid-read
    * ignore server complaining about duplicate chunks, it's fine
  * help chrome not get stuck when it sees a file named `aux.h` on windows
  * notice and panic on more errors
    * and stop trying to do things after something died to an unhandled exception
  * less confusing debug messages regarding sha512 library selection

* latest gzip edition of the sfx is [v0.11.18](https://github.com/9001/copyparty/releases/tag/v0.11.18)

## new features suggested by kipu
* pause uploads by setting `parallel uploads` to `0`
* increase max `parallel uploads` to 16 (using +/- buttons) and 64 (by manual text entry) to accomodate sad american internet connections
* also look for `cover.jpg` and `cover.png` as folder thumbnails by default, adjustable with `--th-covers`
* change the description in the sfx so the corruption warning is the first plaintext you see

## other new features
* search ui could be visibly confusing if the final text entry event happened in the middle of a search
* adjustable `tint` on the audio-player progressbar to make buffering updates less visually distracting
* per-http-connection request counter appended to the transfer speed summary

## bugfixes
* ctrl-clicking folders in the directory tree didn't open them in a new tab
* javascript panic-screen could display the wrong stack in some cases

* if upgrading from [v0.11.20](https://github.com/9001/copyparty/releases/tag/v0.11.20) or later and you use `-e2ts` to index audio tags:

  * if you have expensive `-mtp` parsers (bpm/key) and a huge database (or a slow server), then make a backup of the db before `-e2tsr` and use https://github.com/9001/copyparty/tree/master/bin#dbtoolpy to transfer your tags to the new db
* however if upgrading from something before that, then your database will be wiped anyways so forget the `-e2tsr` stuff above, check the [v0.11.20](https://github.com/9001/copyparty/releases/tag/v0.11.20) notes instead

* icon-generator: realize it's not a file extension when a whitespace appears
* discard and regenerate corrupted databases instead of giving up

# 2021-0620-1732  `v0.11.20`  database.rmvb

**this release will discard and rebuild your database** (`.hist/up2k.db`)
* no actions necessary, it just takes a while
* no additional steps to consider since [v0.11.1](https://github.com/9001/copyparty/releases/tag/v0.11.1) actually
* the old database will be backed up automatically just in case
* if you have expensive `-mtp` parsers (bpm/key) and a huge database (or a slow server), you can transfer your tags to the new db using https://github.com/9001/copyparty/tree/master/bin#dbtoolpy

reason: [v0.11.12](https://github.com/9001/copyparty/releases/tag/v0.11.12) changed the file checksum algorithm slightly, causing a mismatch between the server and client, and as a result:
* upload deduplication has been unpredictable
* filesearch could return false-negatives

## new features
* much faster filesearch in chrome
* skip hidden colums in the /np text
* support cygpaths when pointing to mtag tools

## bugfixes
* uploading folders through the up2k client would fail if the folder already existed on the server; now they merge
* change up2k hashlen to 33 bytes / 44 chars (mod24 bits) to fit base64 better, avoiding any padding bugs
* prefer client IP rater than proxy IP as fallback value when `--rproxy` is configured out of bounds
* correct indexing of files with names containing backslash on linux/macos

## other notes
* the latest gzip edition of the sfx is [v0.11.18](https://github.com/9001/copyparty/releases/tag/v0.11.18)

  * [v0.11.16](https://github.com/9001/copyparty/releases/tag/v0.11.16): more accurate audio equalizer
* the latest gzip edition of the sfx is [v0.11.18](https://github.com/9001/copyparty/releases/tag/v0.11.18)

## new features

# 2021-0617-2230  `v0.11.18`  seamless

* drop-in upgrade; no additional steps to consider since [v0.11.1](https://github.com/9001/copyparty/releases/tag/v0.11.1)
* no important fixes, mostly new features
* recent important updates:
  * [v0.11.14](https://github.com/9001/copyparty/releases/tag/v0.11.14) fixed a deadlock in the thumbnails feature which was added in [v0.11.0](https://github.com/9001/copyparty/releases/tag/v0.11.0)

## notes
this release includes [copyparty-sfx-gz.py](https://github.com/9001/copyparty/releases/download/v0.11.18/copyparty-sfx-gz.py), an additional sfx build which uses gzip compression rather than the usual bzip2; only useful for smoketests on minimal python builds. Note that both past and future releases can be converted from bzip2 to gzip by running [copyparty-repack.sh](https://github.com/9001/copyparty/blob/master/scripts/copyparty-repack.sh) on linux/macos/windows-msys2; this will produce the additional sfx in this release, `copyparty-extras/sfx-full/copyparty-sfx-gz.py` (see [sfx-repack](https://github.com/9001/copyparty#sfx-repack) for more info)

## new features
* **(almost) gapless audio playback!** partially powered by:
  * url suffix `?cache` to get a response without any `Cache-Control` directives
  * and using events for end-of-track instead of polling
* hotkey `b` to toggle breadcrumbs / directory tree sidebar
  * hotkey `p` is now play/pause
  * hotkey `m` is now parent-directory
* hilight the playing track in gallery mode too
* toggle to disable the now-playing clipboard buttons
* added lots of tooltips
  * threw aray the competing tooltip implementations and did a single ok one
* more accurate error-messages on upload failures due to filesystem permissions
* add another output to the sfx repacker (gzip-compressed python sfx)

## bugfixes
* file selection after switching from grid to list
* playback into next folder if the tree sidebar is closed
* show the link to exit search results even if columns are hidden
* make an effort to terminate clients cleanly on shutdown
* py2 volume listing with `-e2d`

## new features
* hotkey `m` for play/pause
* make audio gain adjustable
  * cranking it way up behaves differently depending on browser; firefox adds a compressor, chrome just ***goes***
  * funfact, the base gain is `0.94` to avoid clipping due to imperfections in the equalizer curve
* responsive settings layout
* other minor ux tweaks
  * brightmode contrast and player widget
  * add gridlines to the files table
* print summary when thumbcache cleanup finishes

## bugfixes
* the audio-eq ui didn't handle leading/trailing decimals too well
* thumbcache-eviction mostly broke in [v0.11.12](https://github.com/9001/copyparty/releases/tag/v0.11.12) (and somehow nothing else so far)

big changes, **bugs likely**, keep [v0.11.11](https://github.com/9001/copyparty/releases/tag/v0.11.11) as a fallback and go whine in the irc
* otherwise a drop-in upgrade; no additional steps to consider since [v0.11.1](https://github.com/9001/copyparty/releases/tag/v0.11.1)

nothing really important happened since [v0.11.6](https://github.com/9001/copyparty/releases/tag/v0.11.6); quick summary:
* [v0.11.9](https://github.com/9001/copyparty/releases/tag/v0.11.9): fix zip/tar of recursive symlinks
* [v0.11.10](https://github.com/9001/copyparty/releases/tag/v0.11.10): fix direct tls connections
* [v0.11.11](https://github.com/9001/copyparty/releases/tag/v0.11.11): fix live-rescan without a root folder
* this ver only fixes unlikely edge-cases

## new features:
* folder thumbnails if they contain `folder.jpg` or `folder.png`, good for music servers
* `--hist` stores the per-volume databases and thumbnails all in one place, instead of the `.hist` subfolders in each volume
* `--no-hash` disables file hashing, good for a simple searchable index, but keep in mind it disables file-search and dupe detection
  * both this and `--hist` can be adjusted per-volume with volflags, see readme
* thumbnails keep transparency
* `--th-ff-jpg` fixes video thumbnails if your FFmpeg is bad (macos)
* more info in the [admin panel](https://user-images.githubusercontent.com/241032/121763646-15422780-cb3e-11eb-8932-130af39acb48.png) (num.files queued for hashing or tags)
* `--css-browser` to set [custom CSS](https://user-images.githubusercontent.com/241032/121763647-15dabe00-cb3e-11eb-90a4-1628a072545c.png)
  * use `.prologue.html` or `.epilogue.html` to do this per-folder; that allows for javascript too
* cygpaths for windows, `-v c:\users::r` and `-v /c/users::r` both work now
* extremely minor (i think) performance improvements which probably drown in the new bloat

## bugfixes:
* mounting a volume deep inside another volume will no longer create additional databases, avoiding rescan of files in intermediate folders
  * backwards-compat so it will continue to use any intermediate databases made by v0.11.11 or older
* better error message on basic-upload into a folder that doesn't exist / without permission
* minor race introduced in 0.11.1 which could be triggered by an upload really early after starting the server

## new features
* add [hash-wasm](https://github.com/Daninet/hash-wasm) as preferred fallback up2k hasher, does 250 MiB/s so like 7x faster

  * technically this allows for a single sha512 over the whole file rather than chunks...
* in gallery mode, open files in a new tab if there's a selection active
* `--ls`, which can be used to look for dangerous symlinks
  * `--ls '**,*,ln,p,r'` does a full scan of all volumes (as all users) and refuses to start if there are links leaving the vols (see `--help`)
* other minor optimizations

## bugfixes
* metadata indexing with single-threaded backends
* loader animation appears over thumbnails too
* restore support for firefox 12
