v1.18.4

togglebutton in the ui switches between 2 (off/default) and
1 (on/quick) confirmations; global-option `--qdel` sets the default

setting `--qdel=0` changes the togglebutton to switch
between 1 (off/default) confirmations and 0 (on)

in other words, when the ui-button is enabled, it
always reduces the number of confirmations by one

+# 2025-0527-1939  `v1.17.2`  pushing chrome to the limits (and then some)
+
+## 🧪 new features
+
+* not this time
+
+## 🩹 bugfixes
+
+* up2k: improve file-hashing speed on recent versions of google chrome e3e51fb8
+  * speed increased from 319 to 513 MiB/s by default (but older chrome versions did 748...)
+  * read the commit message for the full story, but basically chrome has gotten gradually slower over the past couple versions (starting from v133) and this makes it slightly less bad again
+  * hashing speed can be further improved from `0.5` to `1.1` GiB/s by enabling the `[wasm]` option in the `[⚙️] settings` tab
+    * this option can be made default-enabled with `--nosubtle 137` but beware that this increases the chances of running into browser-bugs (foreshadowing...)
+* up2k: fix errorhandler for browser-bugs (oom and such) 49c71247
+  * because [chrome-bug 383568268](https://issues.chromium.org/issues/383568268) is about to make a [surprise return?!](https://issues.chromium.org/issues/383568268#comment14)
+* #168 fix uploading into shares if path-based proxying is used 9cb93ae1
+* #165 unconditionally heed `--rp-loc` 84f5f417
+  * the config-option for [path-based proxying](https://github.com/9001/copyparty/#reverse-proxy) was ignored if the reverse-proxy was untrusted; this was confusing and not strictly necessary
+
+## 🔧 other changes
+
+* #166 the nixos module was improved once more (thx @msfjarvis!) 48470f6b 60fb1207
+* added usage instructions to [minimal-up2k.js](https://github.com/9001/copyparty/tree/hovudstraum/contrib/plugins#example-browser-js), the up2k-ui [simplifier](https://user-images.githubusercontent.com/241032/118311195-dd6ca380-b4ef-11eb-86f3-75a3ff2e1332.png) 1d308eeb

+
+## 🌠 fun facts
+
+* this release was tested using an [unreliable rdp connection](https://a.ocv.me/pub/g/nerd-stuff/PXL_20250526_021207825.jpg) through two ssh-jumphosts to a qemu win10 vm back home from the bergen-oslo night train wifi

+## build from scratch
+
+how the sausage is made:
+
+to get started, first `cd` into the `scripts` folder
+
+* the first step is the webdeps; they end up in `../copyparty/web/deps/` for example `../copyparty/web/deps/marked.js.gz` -- if you need to build the webdeps, run `make -C deps-docker`
+  * this needs rootless podman and the `podman-docker` compat-layer to pretend it's docker, although it *should* be possible to use rootful/rootless docker too
+  * if you don't have rootless podman/docker then `sudo make -C deps-docker` is fine too
+  * alternatively, you can entirely skip building the webdeps and instead extract the compiled webdeps from the latest github release with `./make-sfx.sh fast dl-wd`
+
+* next, build `copyparty-sfx.py` by running `./make-sfx.sh gz fast`
+  * this is a dependency for most of the remaining steps, since they take the sfx as input
+  * removing `fast` makes it compress better
+  * removing `gz` too compresses even better, but startup gets slower
+
+* if you want to build the `.pyz` standalone "binary", now run `./make-pyz.sh`
+
+* if you want to build a pypi package, now run `./make-pypi-release.sh d`
+
+* if you want to build a docker-image, you have two options:
+  * if you want to use podman to build all docker-images for all supported architectures, now run `(cd docker; ./make.sh hclean; ./make.sh hclean pull img)`
+  * if you want to use docker to build all docker-images for your native architecture, now run `sudo make -C docker`
+  * if you want to do something else, please take a look at `docker/make.sh` or `docker/Makefile` for inspiration
+
+* if you want to build the windows exe, first grab some snacks and a beer, [you'll need it](https://github.com/9001/copyparty/tree/hovudstraum/scripts/pyinstaller)
+
+the complete list of buildtime dependencies to do a build from scratch is as follows:
+
+* on ubuntu-server, install podman or [docker](https://get.docker.com/), and then `sudo apt install make zip bzip2`
+  * because ubuntu is specifically what someone asked about :-p
