+try to avoid race conditions in caching proxies
+(primarily cloudflare, but probably others too)
+by means of the most obvious solution possible:
+
+just as each file has finished uploading, use
+the server's external URL to download the file
+so that it ends up in the cache, warm and snug
+
+this intentionally delays the upload response
+as it waits for the file to finish downloading
+before copyparty is allowed to return the URL
+
+NOTE: you must edit this script before use,
+  replacing https://example.com with your URL
+
+NOTE: if the files are only accessible with a
+  password and/or filekey, you must also add
+  a cromulent password in the PASSWORD field
+
+NOTE: needs either wget, curl, or "requests":
+  python3 -m pip install --user -U requests
+
+
+example usage as global config:
+    --xau j,t10,bin/hooks/into-the-cache-it-goes.py
+
+parameters explained,
+    xau = execute after upload
+    j   = this hook needs upload information as json (not just the filename)
+    t10 = abort download and continue if it takes longer than 10sec
+
+example usage as a volflag (per-volume config):
+    -v srv/inc:inc:r:rw,ed:xau=j,t10,bin/hooks/into-the-cache-it-goes.py
+                           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+    (share filesystem-path srv/inc as volume /inc,
+     readable by everyone, read-write for user 'ed',
+     running this plugin on all uploads with params explained above)
+
+example usage as a volflag in a copyparty config file:
+    [/inc]
+      srv/inc
+      accs:

+# 2024-0716-0457  `v1.13.4`  descript.ion
+
+## new features
+
+* "medialinks"; instead of the usual hotlink, the basic-uploader (as used by sharex and such) can return a link that opens the file in the media viewer c9281f89
+  * enable for all uploads with volflag `medialinks`, or just for one upload by adding `?media` to the post url
+* thumbnails are now fully compatible with dirkeys/filekeys 52e06226
+* `--th-covers` will respect filename order, selecting the first matching filename as the folder thumbnail 1cdb1702
+* new hook: [bittorrent downloader](https://github.com/9001/copyparty/tree/hovudstraum/bin/hooks#on-message) bd3b3863 803e1565
+* hooks: d749683d
+  * can be restricted to only run when user has specific permissions
+  * user permissions are also included in the json message to the hook
+  * new syntax to prepend args to the hook's command
+  * (all this will be better documented after some additional upcoming hook-related features, see `--help-hooks` for now)
+* support `descript.ion` usenet metadata; will parse and render into directory listings when possible 927c3bce
+  * directory listings are now 2% slower, eh who's keeping count anyways
+* tftp-server: 45259251
+  * improved support for buggy clients
+  * improved ipv6 support, especially on macos
+  * improved robustness on unreliable networks
+* #85 new option `--gsel` to default-enable the client setting to select files by ctrl-clicking them in the grid 9a87ee2f
+* music player: set audio volume by scrollwheel 36d6d29a
+
+## bugfixes
+
+* race-the-beam (downloading an unfinished upload) could get interrupted near the end, requiring a manual resume in the browser's download manager to finish f37187a0
+* ftp-server: when accessing the root folder of servers without a root folder, it could mention inaccessible folders 84e8e1dd
+* ftp-server: uploads will automatically replace existing files if user has delete perms 0a9f4c60
+  * windows 2000 expects this behavior, otherwise it'll freak out and delete stuff and then not actually upload it, nice
+  * new option `--ftp-no-ow` restores old default behavior of rejecting upload if target filename exists
+* music player:
+  * stop trying to recover from a corrupted file if the user already fixed it manually 55a011b9
+  * support downloading the currently playing song regardless of current folder c06aa683
+* music player preloader: db6059e1
+  * stop searching after 5 folders of nothing
+  * don't crash playback by walking into error-pages
+* `--og` (rich discord embeds) was incompatible with viewing markdown docs d75a2c77
+* `--cgen` (configfile generator) much less jank d5de3f2f
+
+## other changes
+
+* mention that HTTP/2 is still usually slower than HTTP/1.1 dfe7f1d9
+* give up much sooner if a client is supposed to send a request body but isn't c549f367
+* support running copyparty as a server on windows 2000 and winXP 8c73e0cb 2fd12a83
+* updated deps 6e58514b
+  * copyparty.exe: python 3.12, pillow 10.4, pyinstaller 6.9
+  * dompurify 3.1.6

ed	132a83501e	add chunk stitching; twice as fast long-distance uploads: rather than sending each file chunk as a separate HTTP request, sibling chunks will now be fused together into larger HTTP POSTs which results in unreasonably huge speed boosts on some routes ( `2.6x` from Norway to US-East, `1.6x` from US-West to Finland ) the `x-up2k-hash` request header now takes a comma-separated list of chunk hashes, which must all be sibling chunks, resulting in one large consecutive range of file data as the post body a new global-option `--u2sz`, default `1,64,96`, sets the target request size as 64 MiB, allowing the settings ui to specify any value between 1 and 96 MiB, which is cloudflare's max value this does not cause any issues for resumable uploads; thanks to the streaming HTTP POST parser, each chunk will be verified and written to disk as they arrive, meaning only the untransmitted chunks will have to be resent in the event of a connection drop -- of course assuming there are no misconfigured WAFs or caching-proxies the previous up2k approach of uploading each chunk in a separate HTTP POST was inefficient in many real-world scenarios, mainly due to TCP window-scaling behaving erratically in some IXPs / along some routes a particular link from Norway to Virginia,US is unusably slow for the first 4 MiB, only reaching optimal speeds after 100 MiB, and then immediately resets the scale when the request has been sent; connection reuse does not help in this case on this route, the basic-uploader was somehow faster than up2k with 6 parallel uploads; only time i've seen this	2024-07-21 23:35:37 +00:00
