 **protip:** you can avoid scaring away users with [docs/minimal-up2k.html](docs/minimal-up2k.html) which makes it look [much simpler](https://user-images.githubusercontent.com/241032/118311195-dd6ca380-b4ef-11eb-86f3-75a3ff2e1332.png)

 the up2k UI is the epitome of polished inutitive experiences:
 * "parallel uploads" specifies how many chunks to upload at the same time
 * `[🏃]` analysis of other files should continue while one is uploading
-* `[💭]` ask for confirmation before files are added to the list
-* `[💤]` sync uploading between other copyparty tabs so only one is active
-* `[🔎]` switch between upload and file-search mode
+* `[💭]` ask for confirmation before files are added to the queue
+* `[💤]` sync uploading between other copyparty browser-tabs so only one is active
+* `[🔎]` switch between upload and [file-search](#file-search) mode
+  * ignore `[🔎]` if you add files by dragging them into the browser

 and then theres the tabs below it,
-* `[ok]` is uploads which completed successfully
-* `[ng]` is the uploads which failed / got rejected (already exists, ...)
+* `[ok]` is the files which completed successfully
+* `[ng]` is the ones that failed / got rejected (already exists, ...)
 * `[done]` shows a combined list of `[ok]` and `[ng]`, chronological order
 * `[busy]` files which are currently hashing, pending-upload, or uploading
  * plus up to 3 entries each from `[done]` and `[que]` for context
 * `[que]` is all the files that are still queued

+note that since up2k has to read each file twice, `[🎈 bup]` can *theoretically* be up to 2x faster in some extreme cases (files bigger than your ram, combined with an internet connection faster than the read-speed of your HDD)
+
+if you are resuming a massive upload and want to skip hashing the files which already finished, you can enable `turbo` in the `[⚙️] config` tab, but please read the tooltip on that button

 ### file-search

+dropping files into the browser also lets you see if they exist on the server

-in the `[🚀 up2k]` tab, after toggling the `[🔎]` switch green, any files/folders you drop onto the dropzone will be hashed on the client-side. Each hash is sent to the server which checks if that file exists somewhere already

+
+when you drag/drop files into the browser, you will see two dropzones: `Upload` and `Search`
+
+> on a phone? toggle the `[🔎]` switch green before tapping the big yellow Search button to select your files
+
+the files will be hashed on the client-side, and each hash is sent to the server, which checks if that file exists somewhere

 files go into `[ok]` if they exist (and you get a link to where it is), otherwise they land in `[ng]`
 * the main reason filesearch is combined with the uploader is cause the code was too spaghetti to separate it out somewhere else, this is no longer the case but now i've warmed up to the idea too much

 adding the same file multiple times is blocked, so if you first search for a file and then decide to upload it, you have to click the `[cleanup]` button to discard `[done]` files (or just refresh the page)

-note that since up2k has to read the file twice, `[🎈 bup]` can be up to 2x faster in extreme cases (if your internet connection is faster than the read-speed of your HDD)

+
+quick explanation of the buttons,  
+* `[✅ apply rename]` confirms and begins renaming
+* `[❌ cancel]` aborts and closes the rename window
+* `[↺ reset]` reverts any filename changes back to the original name
+* `[decode]` does a URL-decode on the filename, fixing stuff like `&amp;` and `%20`
+* `[advanced]` toggles advanced mode
+
+advanced mode: rename files based on rules to decide the new names, based on the original name (regex), or based on the tags collected from the file (artist/title/...), or a mix of both
+
+in advanced mode,  
+* `[case]` toggles case-sensitive regex
+* `regex` is the regex pattern to apply to the original filename; any files which don't match will be skipped
+* `format` is the new filename, taking values from regex capturing groups and/or from file tags
+  * very loosely based on foobar2000 syntax
+* `presets` lets you save rename rules for later

+available functions:
+* `$lpad(text, length, pad_char)`

+so,
+
+say you have a file named [`meganeko - Eclipse - 07 Sirius A.mp3`](https://www.youtube.com/watch?v=-dtb0vDPruI) (absolutely fantastic album btw) and the tags are: `Album:Eclipse`, `Artist:meganeko`, `Title:Sirius A`, `tn:7`
+
+you could use just regex to rename it:
+* `regex` = `(.*) - (.*) - ([0-9]{2}) (.*)`
+* `format` = `(3). (1) - (4)`
+* `output` = `07. meganeko - Sirius A.mp3`
+
+or you could use just tags:
+* `format` = `$lpad((tn),2,0). (artist) - (title).(ext)`
+* `output` = `7. meganeko - Sirius A.mp3`
+
+or a mix of both:
+* `regex` = ` - ([0-9]{2}) `
+* `format` = `(1). (artist) - (title).(ext)`
+* `output` = `07. meganeko - Sirius A.mp3`
+
+the metadata keys you can use in the format field are the ones in the file-browser table header (whatever is collected with `-mte` and `-mtp`)

+## file indexing
+
+file indexing relies on two database tables, the up2k filetree (`-e2d`) and the metadata tags (`-e2t`), stored in `.hist/up2k.db`. Configuration can be done through arguments, volume flags, or a mix of both.

 through arguments:
 * `-e2d` enables file indexing on upload
-* `-e2ds` scans writable folders for new files on startup
-* `-e2dsa` scans all mounted volumes (including readonly ones)
+* `-e2ds` also scans writable folders for new files on startup
+* `-e2dsa` also scans all mounted volumes (including readonly ones)
 * `-e2t` enables metadata indexing on upload
-* `-e2ts` scans for tags in all files that don't have tags yet

+* `-e2ts` also scans for tags in all files that don't have tags yet
+* `-e2tsr` also deletes all existing tags, doing a full reindex

 the same arguments can be set as volume flags, in addition to `d2d` and `d2t` for disabling:
-* `-v ~/music::r:ce2dsa:ce2tsr` does a full reindex of everything on startup
-* `-v ~/music::r:cd2d` disables **all** indexing, even if any `-e2*` are on
-* `-v ~/music::r:cd2t` disables all `-e2t*` (tags), does not affect `-e2d*`
+* `-v ~/music::r:c,e2dsa:c,e2tsr` does a full reindex of everything on startup
+* `-v ~/music::r:c,d2d` disables **all** indexing, even if any `-e2*` are on
+* `-v ~/music::r:c,d2t` disables all `-e2t*` (tags), does not affect `-e2d*`

 note:
+* the parser currently can't handle `c,e2dsa,e2tsr` so you have to `c,e2dsa:c,e2tsr`
 * `e2tsr` is probably always overkill, since `e2ds`/`e2dsa` would pick up any file modifications and `e2ts` would then reindex those, unless there is a new copyparty version with new parsers and the release note says otherwise
 * the rescan button in the admin panel has no effect unless the volume has `-e2ds` or higher

+to save some time, you can choose to only index filename/path/size/last-modified (and not the hash of the file contents) by setting `--no-hash` or the volume-flag `:c,dhash`, this has the following consequences:
 * initial indexing is way faster, especially when the volume is on a network disk
 * makes it impossible to [file-search](#file-search)

+if you set `--no-hash`, you can enable hashing for specific volumes using flag `:c,ehash`
+
+
+## upload rules
+
+set upload rules using volume flags,  some examples:
+
+* `:c,sz=1k-3m` sets allowed filesize between 1 KiB and 3 MiB inclusive (suffixes: b, k, m, g)
+* `:c,nosub` disallow uploading into subdirectories; goes well with `rotn` and `rotf`:
+* `:c,rotn=1000,2` moves uploads into subfolders, up to 1000 files in each folder before making a new one, two levels deep (must be at least 1)
+* `:c,rotf=%Y/%m/%d/%H` enforces files to be uploaded into a structure of subfolders according to that date format
+  * if someone uploads to `/foo/bar` the path would be rewritten to `/foo/bar/2021/08/06/23` for example
+  * but the actual value is not verified, just the structure, so the uploader can choose any values which conform to the format string
+    * just to avoid additional complexity in up2k which is enough of a mess already
+* `:c,lifetime=300` delete uploaded files when they become 5 minutes old
+
+you can also set transaction limits which apply per-IP and per-volume, but these assume `-j 1` (default) otherwise the limits will be off, for example `-j 4` would allow anywhere between 1x and 4x the limits you set depending on which processing node the client gets routed to
+
+* `:c,maxn=250,3600` allows 250 files over 1 hour from each IP (tracked per-volume)
+* `:c,maxb=1g,300` allows 1 GiB total over 5 minutes from each IP (tracked per-volume)
+
+
+## compress uploads
+
+files can be autocompressed on upload,  either on user-request (if config allows) or forced by server-config
+
+* volume flag `gz` allows gz compression
+* volume flag `xz` allows lzma compression
+* volume flag `pk` **forces** compression on all files
+* url parameter `pk` requests compression with server-default algorithm
+* url parameter `gz` or `xz` requests compression with a specific algorithm
+* url parameter `xz` requests xz compression
+
+things to note,
+* the `gz` and `xz` arguments take a single optional argument, the compression level (range 0 to 9)
+* the `pk` volume flag takes the optional argument `ALGORITHM,LEVEL` which will then be forced for all uploads, for example `gz,9` or `xz,0`
+* default compression is gzip level 9
+* all upload methods except up2k are supported
+* the files will be indexed after compression, so dupe-detection and file-search will not work as expected
+

 ## database location

+in-volume (`.hist/up2k.db`, default) or somewhere else
+
 copyparty creates a subfolder named `.hist` inside each volume where it stores the database, thumbnails, and some other stuff

 this can instead be kept in a single place using the `--hist` argument, or the `hist=` volume flag, or a mix of both:
-* `--hist ~/.cache/copyparty -v ~/music::r:chist=-` sets `~/.cache/copyparty` as the default place to put volume info, but `~/music` gets the regular `.hist` subfolder (`-` restores default behavior)
+* `--hist ~/.cache/copyparty -v ~/music::r:c,hist=-` sets `~/.cache/copyparty` as the default place to put volume info, but `~/music` gets the regular `.hist` subfolder (`-` restores default behavior)

 * markdown edits are always stored in a local `.hist` subdirectory

 ## metadata from audio files

+set `-e2t` to index tags on upload

 `-mte` decides which tags to index and display in the browser (and also the display order), this can be changed per-volume:
-* `-v ~/music::r:cmte=title,artist` indexes and displays *title* followed by *artist*
+* `-v ~/music::r:c,mte=title,artist` indexes and displays *title* followed by *artist*

 if you add/remove a tag from `mte` you will need to run with `-e2tsr` once to rebuild the database, otherwise only new files will be affected

 `-mtm` can be used to add or redefine a metadata mapping, say you have media files with `foo` and `bar` tags and you want them to display as `qux` in the browser (preferring `foo` if both are present), then do `-mtm qux=foo,bar` and now you can `-mte artist,title,qux`

  * server writes chunks into place based on the hash
 * client does another handshake with the hashlist; server replies with OK or a list of chunks to reupload

+up2k has saved a few uploads from becoming corrupted in-transfer already; caught an android phone on wifi redhanded in wireshark with a bitflip, however bup with https would *probably* have noticed as well (thanks to tls also functioning as an integrity check)

+
+## why chunk-hashes
+
+a single sha512 would be better, right?
+
+this is due to `crypto.subtle` not providing a streaming api (or the option to seed the sha512 hasher with a starting hash)
+
+as a result, the hashes are much less useful than they could have been (search the server by sha512, provide the sha512 in the response http headers, ...)
+
+hashwasm would solve the streaming issue but reduces hashing speed for sha512 (xxh128 does 6 GiB/s), and it would make old browsers and [iphones](https://bugs.webkit.org/show_bug.cgi?id=228552) unsupported
