get_local_libraries unpacked "line.rsplit(maxsplit=3)" into three names, but
maxsplit=3 yields up to four fields. seaf-cli prints "name id path" separated
by whitespace, so any library whose name contains a space produced a fourth
field and raised ValueError, which nothing caught.
The failure only appeared after the first run: the list is empty until a
library has been synced, so a container would work when it was set up and then
crash on every restart.
seaf-cli list --json returns name, id and path as structured fields, which
display output cannot represent unambiguously for names or paths containing
whitespace. Its exit code is now checked and unreadable output is reported as
a daemon error instead of a traceback.
The image smoke check asserts that the installed seaf-cli offers --json and
--token, so a future version bump that drops either fails the build rather
than the container.
Neither LD_LIBRARY_PATH nor PYTHONPATH is set in the base image, so
appending them unconditionally left a trailing ':'. An empty entry in a
colon-separated search path means the working directory, and Python
resolved it to /dsc on sys.path. Append the separator only when the
variable is already non-empty.
Reported by the automated review on #11.
Seafile discontinued linux-clients.seafile.com: it resolves but accepts
no connections on 80 or 443, and the official docs no longer mention APT
at all. Every `docker build` has failed since. Upstream now ships the CLI
as an AppImage, so install 9.0.19 from the download site.
The AppImage is unpacked rather than executed. Running one needs FUSE and
so a privileged container, and its self-extraction also fails when the
build host cannot execute the payload's architecture. Unpacking the
appended squashfs directly avoids both.
Also add the bundled seafile/pysearpc bindings to the venv path. The APT
package installed them system-wide, where `venv --system-site-packages`
picked them up; dsc imports seafile directly for RPC, not only through
seaf-cli, so it broke when that implicit dependency went away.
Drops apt-key, pins the version, and verifies a SHA256 before unpacking.
Build-time smoke checks assert the seaf-cli subcommands and the app's own
imports.
Note: the AppImage is x86_64-only, and upstream publishes no digest or
signature, so the pinned checksum is trust-on-first-use.
