The hash was checked when there was one and skipped when there was not,
which is the wrong way round: everything fetched here is either run or
parsed by something written in C++, and the case with no hash is the one
where that matters most and says least.
Not hypothetical. GitHub publishes a digest for whisper.cpp v1.9.1 and for
llama.cpp today, and publishes none for whisper.cpp v1.8.0 and older, so
anything reaching for an older tag would have installed an executable
nobody checked.
_wait_ready can raise rather than return, and the process it was waiting on
is ours with nothing else holding a reference to it. Leaving it running
leaks a loaded model with nobody left to ask it anything, which is the
whole failure this class is careful about everywhere else. Found by two
stand-in servers still running after a test run.
Two programs, one treatment: ask GitHub what was released, take the build
this machine can run, check it against the sha256 the index published, then
fetch a model from Hugging Face the same way and keep one server up on a
port of its own.
Neither list is written into the source. A model catalogue in here means a
release of Dikte for every model somebody else publishes, and a pinned
version means one for every whisper.cpp release; both are somebody else's
news. The lists are read at the moment the settings window is opened and
cached for a few hours, and a cache that has gone stale still answers when
the network does not.
Nothing that lands on disk is trusted for having arrived, which matters
more here than usual because half of what is fetched is a program Dikte
then runs.
