A build carries the OpenSSL of the machine it was built on, and that
OpenSSL has one directory compiled into it as the only place it looks for
certificates. For an AppImage built on Ubuntu that is /usr/lib/ssl, which
Arch, Fedora and openSUSE do not have, so on any of them every HTTPS
request fails with CERTIFICATE_VERIFY_FAILED: transcription and cleanup
report it as a rejected key, and the model downloads fail too.
Ask the machine instead, from the list curl and Go use, and only when the
build's own answer turns out not to exist. The store on the machine
rather than a copy carried along, because a copy goes stale as roots are
rotated and would ignore a certificate somebody added themselves. Anybody
who has already set SSL_CERT_FILE is left alone.
A Mac keeps temporary directories under /var, which is a symlink to
/private/var, and target() resolves what it is handed because a bundle
reached through a symlink is still that bundle. So the login item named
/private/var/... while the test held /var/..., and the two spellings of
one path did not match.
Installing meant cloning the repository and running a shell script, which
is a fair ask of somebody who already has a terminal open and no ask at
all of anybody else. The releases page now carries an AppImage and a disk
image per Mac architecture: a push to master rebuilds a rolling "latest",
a v* tag publishes a version and leaves it there, and the Run button in
the Actions tab raises the number by running scripts/release.sh, which is
the same script and not a second copy of what it does.
Two things in the application had to give for that. A build has no
__main__.py on disk, and an AppImage is mounted somewhere new every run,
so the command a shortcut is registered with cannot go on being this
interpreter and this file; ipc.launcher() answers with the AppImage or
the bundle instead. And a build carries its own libstdc++, which every
process it starts inherits through LD_LIBRARY_PATH and none of them can
live with: ffmpeg, ydotool and wl-copy are the distribution's binaries
built against the distribution's libraries, and AppImageLauncher, which
is what starting the AppImage again goes through, refuses outright.
integrate.py puts that variable back before anything else runs.
Nothing installs itself over an installation that is already there.
install.sh's menu entry, install-mac.sh's login item and the desktop file
AppImageLauncher writes are each recognised and left alone, so trying a
download once does not quietly move the machine onto it. `dikte
integrate` is how you ask for it outright, and --remove takes it back.
The disk image carries an ffmpeg, pinned and checksummed, because macOS
records through one and ships nothing like it. It is signed ad-hoc and
not with an Apple certificate, so a first launch is refused until Open
Anyway and the permissions are asked for again after each update; both
READMEs and the release notes say so.
