+
+* new option `--bauth-last` for when you're hosting other [basic-auth](https://developer.mozilla.org/en-US/docs/Web/HTTP/Authentication) services on the same domain 7b94e4ed
+  * makes it possible to log into copyparty as intended, but it still sees the passwords from the other service until you do
+  * alternatively, the other new option `--no-bauth` entirely disables basic-auth support, but that also kills [the android app](https://github.com/9001/party-up)
+
+## bugfixes
+
+* internet explorer isn't working?! FIX IT!!! 9e5253ef
+* audio transcoding was buggy with filekeys enabled b8733653
+* on windows, theoretical chance that antivirus could interrupt renaming files, so preemptively guard against that c8e3ed3a
+
+## other changes
+
+* add a "password" placeholder on the login page since you might think it's asking for a username da26ec36
+* config buttons were jank on iOS b772a4f8
+* readme: [making your homeserver accessible from the internet](https://github.com/9001/copyparty#at-home)

+
+## new features
+
+* while viewing pictures/videos, the scrollwheel can be used to view the prev/next file 844d16b9
+
+## bugfixes
+
+* #81 (scrolling suddenly getting disabled) properly fixed after @icxes found another way to reproduce it (thx) 4f0cad54
+* and fixed at least one javascript glitch introduced in v1.12.0 while adding dirkeys 989cc613
+  * directory tree sidebar could fail to render when popping browser history into the lightbox
+
+## other changes
+
+* music preloader is slightly less hyper f89de6b3

 # recipe for building an exe with nuitka (extreme jank edition)
-#
-# NOTE: win7 and win10 builds both work on win10 but
-#   on win7 they immediately c0000005 in kernelbase.dll
-#
-# first install python-3.6.8-amd64.exe
-#   [x] add to path
-#
+
+NOTE: copyparty runs SLOWER when compiled with nuitka;
+  just use copyparty-sfx.py and/or pyinstaller instead
+
+  ( the sfx and the pyinstaller EXEs are equally fast if you
+  have the latest jinja2 installed, but the older jinja that
+  comes bundled with the sfx is slightly faster yet )
+
+  roughly, copyparty-sfx.py is 6% faster than copyparty.exe
+  (win10-pyinstaller), and copyparty.exe is 10% faster than
+  nuitka, making copyparty-sfx.py 17% faster than nuitka
+
+NOTE: every time a nuitka-compiled copyparty.exe is launched,
+  it will show the windows firewall prompt since nuitka will
+  pick a new unique location in %TEMP% to unpack an exe into,
+  unlike pyinstaller which doesn't fork itself on startup...
+  might be fixable by configuring nuitka differently, idk
+
+NOTE: nuitka EXEs are larger than pyinstaller ones;
+  a minimal nuitka build of just the sfx (with its bundled
+  dependencies) was already the same size as the pyinstaller
+  copyparty.exe which also includes Mutagen and Pillow
+
+NOTE: nuitka takes a lot longer to build than pyinstaller
+  (due to actual compilation of course, but still)
+
+NOTE: binaries built with nuitka cannot run on windows7,
+  even when compiled with python 3.6 on windows 7 itself
+
+NOTE: `--python-flags=-m` is the magic sauce to
+  correctly compile `from .util import Daemon`
+  (which otherwise only explodes at runtime)
+
+NOTE: `--deployment` doesn't seem to affect performance

ed	7b94e4edf3	configurable basic-auth preference; adds options `--bauth-last` to lower the preference for taking the basic-auth password in case of conflict, and `--no-bauth` to entirely disable basic-authentication if a client is providing multiple passwords, for example when "logged in" with one password (the `cppwd` cookie) and switching to another account by also sending a PW header/url-param, then the default evaluation order to determine which password to use is: url-param `pw`, header `pw`, basic-auth header, cookie (cppwd/cppws) so if a client supplies a basic-auth header, it will ignore the cookie and use the basic-auth password instead, which usually makes sense but this can become a problem if you have other webservers running on the same domain which also support basic-authentication --bauth-last is a good choice for cooperating with such services, as --no-bauth currently breaks support for the android app...	2024-04-11 20:15:49 +00:00
