If the event loop is stopped while something holds the exclusive output, the
"log" singleton is now reset so the main thread can print a few more messages
before exiting.
Previously, it ran in the event loop's default executor, which would block until
all its workers were done working.
If Ctrl+C was pressed while input or a password were being read, the
asyncio.run() call in the main thread would be interrupted however, not the
input thread. This meant that multiple key presses (either enter or a second
Ctrl+C) were necessary to stop a running PFERD in some circumstances.
This change instead runs the input functions in daemon threads so they exit as
soon as the main thread exits.
This patch removes quite a few retries and now only retries the ilias
element method. Every other HTTP-interacting method (except for the root
requests) is called from there and should be covered.
In the future we also want to retry the root a few times, but that
will be done after the download sink API is adjusted.
- Renamed module and class because "conductor" didn't make a lot of sense
- Used singleton approach (there's only one stdout after all)
- Redesigned progress bars (now with download speed!)
This allows us to crawl links and represent them in the file system.
Users can choose between an ILIAS-imitation (that optionally
auto-redirects) and a plain text variant.
This doesn't seem to fix the case where an exception bubbles up to the top of
the event loop. It also doesn't seem to fix the case when a KeyboardInterrupt is
thrown, since that never makes its way into the event loop in the first place.
Both of these cases lead to the event loop stopping, which means that the tmp
file cleanup doesn't get executed even though it's inside a "with" or "finally".
