Add keyword-argument description to Cmd.__init__(), and default it to help. Also, add a property .description returning it, and add it to add_parser() so that it shows up in the usage message.
pgit.sh get is not invoked with --create-remote-user-repos by default. For the janware Git servers, this makes CI fail over new repos: Repos from the maintainers are pulled, but before pkg-rebuild-reinstall, repos that the devops user has no remote repo for are purged again and are subseqently missing during build.
Passing --create-remote-user-repos to all pgit.sh get invocations should fix the problem, so do that.
Add a CopyContext class. At this point it mostly acts as a context manager for two FileContext instances, and copying data is the canonical case to use it, hence the name.
- Add optional in_pipe and out_pipe parameters to __init__()
- Add a add_proc_filter() method
Add possibilites to attach input / output pipes to a FileContext instance. Data will be passed through the input pipe between ._get() and .get(), and through the output pipe between .put() and _put().
Add an async open() method which should allow to do what __init__() couldn't, because it's not async, and to match the already existing .close(). It's called by __aenter__() __aexit__() if the FileContext is instantiated as context manager, or at will when the user finds it a good idea.
Cosmetics: The "packages" parameter to some DistroContext's methods has a confusing name in same contexts, notably when mixed with a list of Package instances, so rename it to "pkg_names".
Add an optional "filter: PackageFilter|None" parameter to .select(), and if it's not None, call a new version of ._select() with it.
._select() is not abstract anylonger. Its default implementation filters the results of ._select_by_name(), can be reimplemented by deriving classes for better performance, but doesn't have to.
Rename ._select() to _select_by_name() in Distro and its subclasses. Don't rename .select() itself, because it's going to be a broader interface supporting more select criteria than just package names.
Add global --pkg-filter argument, defaulting to JW_DEFAULT_PKG_FILTER. If it's specified, instantiate a PackageFilterString from it, and initialize App's Distro instance with it.
Add a default_pkg_filter parameter to Distro's constructor defaulting to None, and expose it via the .default_pkg_filter property. As of this commit, no code in jw-pkg does anything meaningful with it.
Commit a19679fec reverted the first attempt to make AsyncSSH reuse one connection during an instance lifetime. That failed because a lot of distribution-specific properties were filled in a new event loop thread started by AsyncRunner, and AsyncSSH didn't like that.
The last commit provided the needed properties as members of the Distro class. This commit is the second part of the solution: Keep one connection around as a class member and reuse it on every _run() invocation.

This commit is the first part of the solution: Move those properties from the App class to the Distro class, and load the Distro class in an async loader. As soon as it's instantiated, it can provide all its properties without cluttering the code with async keywords.
